The eighth generation iDrive system of BMW is built in the car. This system is based on Linux. The UI design is more modern and the operation is more intuitive. At the same time, it is more convenient for the owner to interact with the car by adding a voice assistant that can talk in natural language. For China users, services provided by Tencent and Alibaba will also be added to the system.

In addition, BMW iX also has a brand-new intelligent personal assistant built in. The driver can give the intelligent personal assistant a name he likes and use it as a wake-up word. BMW’s intelligent personal assistant has the ability of natural dialogue and context understanding, and can learn the driving habits of users. Can make better suggestions when performing multiple tasks at the same time.

Through multiple microphones, BMW Intelligent Personal Assistant can also pick up the sound in different areas in the car to distinguish the objects of conversation, and can communicate and operate according to the situation considering the situation of the vehicle and its surrounding environment.

In addition to the built-in BMW’s eighth generation iDrive system, BMW iX can also use mobile phone mapping systems such as Apple CarPlay and Android Auto in the car.

In 2020, 5G technology has been widely popularized in the field of consumer electronics, and many self-owned brand models are also equipped with 5G modules.

Imported/joint venture car companies seem to be relatively conservative about 5G technology, but BMW is still at the forefront. The BMW iX model will be equipped with 5G communication module, which will bring more improvements to people’s travel experience in the fields of entertainment, information, autonomous driving and road safety in the future.

5G will also promote the further application of cloud technology. BMW has transferred a lot of computing power and functions to the BMW cloud, and processed a lot of data and complex tasks through the BMW cloud computing center.

The BMW i4 model released in advance includes two versions, i4 eDrive40 and i4 M50.

▲ Comparison of important parameters of typical luxury brand pure electric coupe

In terms of appearance, BMW i4 is a coupe with short front and rear suspension, thin side beams, frameless doors and streamlined roof.

The front of the car adopts narrow headlights and BMW’s classic "kidney" shape, which has become one of the appearance standards of BMW I series. The i4 M50 can also be equipped with optional M kit, which includes more flamboyant aerodynamic components, larger rims, etc. to make the vehicle look more combative.

▲ BMW i4

As for the power system, i4 adopts BMW’s latest fifth-generation eDrive electric drive system, which integrates the motor, inverter and gearbox, and has the advantages of simple layout and light weight, with an energy density of 2.14kW/kg.

▲ BMW i4 electric drive system

It is worth pointing out that the motor used in the electric drive system is an electrically excited synchronous motor, which has the advantage of maintaining constant torque output in a fairly wide speed range.

The efficient and compact electric drive system gives BMW the opportunity to give excellent power performance to the i4 model. Among them, i4 eDrive40 adopts the rear wheel drive mode, and the peak power of the electric drive system on the rear axle is 250kW (about 340 HP) and the peak torque is 430N?m. It takes only 5.7s to propel this vehicle with a curb weight of 2125kg to accelerate from 0 to 100 km/h.

▲ BMW i4

The i4 M50 adopts four-wheel drive mode, and the front and rear electric drive systems work together. The peak power of the electric four-wheel drive system is 400kW (about 544 HP), and the peak torque reaches an astonishing 795N?m. With such abundant power, it takes only 3.9 seconds for this vehicle with a curb weight of 2290kg to complete the 0~100km/h acceleration.

In terms of batteries, BMW said that the high-voltage lithium battery used in i4 has a higher technical content than the battery of i3 model, so the energy density has increased by about 20%. At present, both i4 eDrive40 and i4 M50 models are equipped with a lithium battery with a capacity of 83.9kWh (usable capacity is 80.7kWh).

▲ BMW i4 battery pack

In order to keep the battery in its best working condition as much as possible, BMW designed an efficient temperature control system for i4. This system is integrated with the battery pack, which can be heated when it is cold and cooled when it is hot, so that the temperature of each position of the battery pack is as stable and consistent as possible.

With the help of the temperature control system, the battery of i4 can not only support the powerful power output of the electric drive system, but also give the i4 model considerable cruising range.

Under the working condition of WLTP, the energy consumption of i4 eDrive40 is 16~20kWh/100km, and its comprehensive cruising range is 590km；. The energy consumption of i4 M50 is 19~24kWh/100km, and its comprehensive cruising range is 510km.

▲ Charging BMW i4

On this basis, BMW also designed a "Combined Charging Unit" for the i4 model, which gave the i4 the ability to charge quickly.

For example, when using fast-filling piles, i4 supports charging power up to 200kW. Assuming that only 10% of the battery energy is available when the vehicle starts charging, people can get about 164km(i4 eDrive40) or 140km(i4 M50) cruising range in just 10 minutes at this power.

If people are not in such a hurry, it’s ok to wait for a while, because the charging speed of i4 in fast charging mode is very fast, and the charging time from 10% to 80% is only 31 minutes (the same is true for i4 eDrive40 and i4 M50).

In terms of intelligent cockpit, BMW i4 adopts a dual screen design with a 12.3-inch display and a 14.9-inch central control screen, which, like BMW iX, can provide quite a lot of information and a quite shocking sensory experience. Moreover, the double screen adopts the design of curved screen and inclines to the driver’s seat at a certain angle, which is the implementation of BMW’s consistent concept of "driver first".

▲ BMW i4 interior

On this basis, i4 is also equipped with a head-up display system to further enhance the visual experience of drivers and passengers. For example, during driving, the display screen will display information such as map, current position, route planning, etc., while the head-up display system will display tips such as vehicle speed, steering tips, lane change recommendations, etc., so that drivers can see intuitive and concise route guidance information without taking their eyes off the road.

On the center console, the i4 model did not keep too many physical buttons, but integrated the functions corresponding to the buttons into the touch screen. The car also adopts BMW’s eighth generation iDrive system, and its interface and functions are basically the same as BMW iX.

At the same time, i4′ s car system integrates Apple CarPlay and Android Auto mapping system, which has a high tolerance for smart devices such as mobile phones and tablets, and can truly realize end-to-end ecological integration. Users can also customize the car system of i4 through the My BMW App application. In the future, i4′ s car system will also support OTA upgrade. With the blessing of 5G communication technology, OTA upgrade will be very fast.

▲ BMW i4 seat

In terms of intelligent driving, the i4 model has SAE L2-class automatic driving capability, with up to about 40 driving assistance functions. Among them, the functions of forward collision warning, speed limit warning and lane departure warning are standard in the whole department, and the optional functions include adaptive cruise with automatic (adjustable) speed limit assistance, road monitoring, steering and lane keeping assistance, traffic light recognition (only available in Germany) and so on.

It is worth pointing out that the adaptive cruise function of i4 can not only adjust the vehicle speed according to the speed of the preceding vehicle and the set distance, but also adjust the vehicle speed according to the road speed limit. The system will call the road speed limit information provided by the navigation system to ensure that the vehicle will not exceed the speed limit, and at the same time let the vehicle drive safely in the lane through the lane departure warning/avoidance function.

The forward collision warning/avoidance function of BMW i4 has also been upgraded. BMW said that i4′ s sensing system can accurately identify vehicles in static or moving state, as well as pedestrians and cyclists. With a more efficient sensing system, i4 can better avoid collisions.

In addition, parking distance assistance and reversing camera are also standard in the whole system, and optional functions include reversing collision warning and panoramic 3D image display.

Among traditional car companies, BMW’s intelligent process can not be underestimated. In the fields of autonomous driving and intelligent cockpit, BMW already has a large number of core technologies, which is pressing for new forces to build cars step by step.

At the same time, BMW’s electrification transformation is also the fastest in the industry. As early as 2014, BMW has mass-produced two models, i3 and i8, laying the foundation for future models. Nowadays, a large wave of pure electric products are put on the market, which shows BMW’s determination in the field of intelligence and electrification.

　　Su Zhi is known as the "gas pass" in Guijie. During the National Day, he and his colleagues conducted daily gas safety inspections.

　　Su Zhi, the vice captain of Beixinqiao Street Comprehensive Administrative Law Enforcement Team, was called "Gas Pass" in Guijie. Yesterday evening, he and his team members came to several catering units in Guijie that needed to be "looked back" according to the analysis of the big data platform of urban management comprehensive law enforcement, and re-examined the gas safety, domestic waste classification and three bags in front of the door. He said: "The introduction of big data platform has improved the efficiency of law enforcement, and the law enforcement team has also carried out co-governance work, which has improved the gas safety awareness of merchants and implemented the responsibility in place."

　　In order to create a good national day holiday and travel environment for the broad masses of the people, the Municipal Urban Management Law Enforcement Bureau deployed the city’s urban management law enforcement departments to strengthen law enforcement inspection during the holiday season, focusing on ensuring the core area and surrounding areas, tourist attractions, bustling commercial areas and characteristic blocks, major transportation hubs and other places, and focusing on solving outstanding environmental problems to ensure the safe operation and stability of the capital and a clean and orderly environmental order. According to the statistics of the Command Center of the Municipal Urban Management Law Enforcement Bureau, on October 1st, the urban management law enforcement departments of the whole city investigated and dealt with 673 illegal acts, and the city’s environmental order was good.

　　Eliminate hidden dangers at the beginning

　　Prevent problems from not "burning"

　　The festive Guijie Street is busy and orderly, full of "urban fireworks". Over the years, there have been no gas safety accidents in Guijie Street, which has brought a safe and peaceful business and dining environment to merchants and diners. Su Zhi said: "Holiday protection is very important, and more efforts have been made in peacetime to eliminate hidden dangers at the beginning and prevent problems before they happen ‘ Burn ’ , is the motto of my colleagues and me. "

　　"To do a good job in gas law enforcement, all parties need to work together, think in one place and make efforts in one place. In particular, we must let merchants understand that strict requirements and strict law enforcement are for the common interests of everyone on this street." Su Zhi introduced that the comprehensive administrative law enforcement team of Beixinqiao Street has carried out "co-governance" with the merchants in its jurisdiction, helping all units to ensure "self-governance", assigning responsibilities for regular self-examination and self-correction, and establishing the awareness that all employees are safety officers. He said: "Merchants themselves have also selected and recommended excellent models of gas use, and everyone has learned from each other. Some merchants have begun to ignore them, and neighboring merchants will give them pressure, because as we all know, this has destroyed everyone’s common business.

　　"In the inspection, we now use the comprehensive big data platform for urban management law enforcement. Every time, with the inspection and input, we form data analysis of the area, which street and which area have high incidence of which key problems, and which gas users have high incidence of which problems. It is clear at a glance and improves the efficiency of law enforcement." Su Zhi introduced that big data analysis can enable law enforcement teams to better combine carpet surveys with key law enforcement.

　　"Doing instead of training"

　　Bring the learning classroom into the law enforcement scene.

　　In order to implement the principle of "whoever enforces the law will popularize the law", Su Zhi also cooperated with the Guijie Management Committee and the gas company to take "online anytime+offline regularly" training for all gas users. He himself became a "gas expert" and answered all kinds of gas safety regulations and policies, especially the common sense, tips and emergency handling in the face of accidents.

　　Su Zhi said: "The Municipal Bureau and Dongcheng District Bureau regularly organize us to conduct on-the-spot training at the law enforcement site every year. The law enforcement site is a learning classroom, and the immersive improvement is rapid."

　　It is understood that, in view of the strong professionalism of gas safety special law enforcement, the Municipal Urban Management Law Enforcement Bureau brought the learning class to the law enforcement site according to the actual needs of the grassroots, sent the backbone of gas safety special law enforcement business to the law enforcement point, and jointly carried out law enforcement inspections with grassroots comprehensive administrative law enforcement team members, on-site guidance and exchange of experience, and taught gas safety special law enforcement skills. Through experiential and interactive teaching, improve the knowledge reserve of gas safety special law enforcement of grassroots law enforcement team members.

　　In order to facilitate learning, the Municipal Urban Management and Law Enforcement Bureau has also produced a short online course and teaching video on gas law enforcement standards for non-resident users. First-line players can watch it in real time through the network and mobile phones, and quickly grasp the key points of gas law enforcement. At present, the cumulative number of clicks on the course has reached more than 50,000.

　　Shi Yue, the captain of the Fifth Team of the Second Brigade of the Law Enforcement Corps of Beijing Urban Management Law Enforcement Bureau, is one of the main teachers of "training by doing". The Law Enforcement Team 5, where he belongs, is responsible for the overall guidance of the special business in the fields of gas safety and underground pipeline protection in the city’s urban management law enforcement system and the law enforcement work of the corresponding municipal urban management authority. As the captain of the Fifth Team, Shi Yue is proficient in gas safety law enforcement, with rich experience and strong sense of responsibility. No matter whether it is holidays, bad weather or late at night in winter, once there is an emergency in gas safety, he always takes the lead and rushes to the scene to investigate and collect evidence at the first time. He always keeps a set of urban management uniforms at home, so that even if there is an emergency at rest, he can put on his uniform and rush to the scene.

　　On the National Day this year, he led the whole team to prepare the law enforcement inspection plan during the festival early. Relying on the comprehensive law enforcement big data platform, he selected key units found to have hidden dangers of gas safety problems in previous inspections for review to ensure that the problems were rectified in place.

　　"Gas safety law enforcement inspection is one of the key law enforcement projects of our urban management law enforcement department on holidays. Every year, I have to spend a few days at work during long holidays. Through repeated inspections, I have been prompted again and again to see that these users in restaurants are using gas. The process is becoming more and more standardized, and I feel that my work is not in vain. It is very gratifying." Shi Yue said.

　　Catch up with others.

　　The whole chain cracked down on gas safety violations.

　　While intensifying law enforcement on gas safety and strictly investigating hidden dangers, urban management law enforcement departments "catch up" with illegal gas clues such as the gas source of illegal liquefied petroleum gas stations found in the inspection, and improve the connection mechanism of case transfer with urban management, public security, market supervision, emergency management, fire rescue and other departments to jointly punish illegal acts.

　　Since the launch of the "100-day Action" for urban operation safety in the whole city, the Law Enforcement Corps of the Municipal Urban Management Law Enforcement Bureau and the Chaoyang District Urban Management Law Enforcement Bureau have inspected the clues of "black gas cylinders" in the previous period and found that there are suspected illegal liquefied gas tanks in a waste express truck, and 14 illegal liquefied gas tanks were seized on the spot; Changping District Urban Management Law Enforcement Bureau and the Public Security Detachment of the Public Security Bureau of the Joint District seized a place where zombie car was used as a mobile selling place for illegal gas cylinders, and 16 illegal gas cylinders and 1 set of inflating device were seized on the spot.

　　On the first day of National Day, the whole city

　　Good environmental order

　　According to the relevant person in charge of the Municipal Urban Management Law Enforcement Bureau, during the National Day, the urban management law enforcement department combined with the "100-day action" of urban operation safety, "cool summer breeze" and "side by side action" and other special law enforcement work, focusing on investigating and dealing with illegal acts such as gas safety, street environmental order, city appearance and landscape, and air pollution prevention and control. Among them, the urban management law enforcement department went deep into various gas-using places such as catering enterprises to comprehensively investigate and eliminate hidden dangers. The urban management law enforcement department will continue to strictly grasp the normalization inspection and law enforcement of epidemic prevention and control in "three types of places" to ensure the safe operation of the city.

　　At the same time, during the National Day, urban management and law enforcement departments strengthened the control of street environmental order, and comprehensively controlled illegal activities such as unlicensed operation, illegal small advertisements, out-of-store operation, open-air barbecue, and open-air burning; Intensify the inspection of outdoor advertisements, plaque signs and night lighting, and promptly urge those responsible to dismantle, clean, repair or replace when problems are found; Require the responsible units of "three guarantees in front of the door" to strictly implement the responsibility system for city appearance and environmental sanitation and improve the level of street environmental order.

　　It is understood that on the eve of the National Day, the urban management law enforcement department has conducted a comprehensive investigation of the jurisdiction in advance in comparison with key areas and law enforcement inspections, concentrated on rectification actions, and charged off the high-risk points one by one to eliminate all kinds of hidden dangers.
