·Unmanned driving is not far from the development of local smart cars in Chongqing

2021-04-25

A car accident occurs a few kilometers away. The vehicle will prompt you to pay attention to safety. If you are tired and thirsty, the vehicle will automatically select a rest point, plan the route, and reserve the seat in advance. If you drive long distance, you will automatically drive to the destination without operating the vehicle... With the development of the automobile industry, people's demands for automobiles are no longer limited to travel. Many foreign top automobile brands have already launched intelligent new concept cars.
In Chongqing, local smart car research has started two or three years ago. The Chongqing Evening News reporter recently learned from the Automobile Office of the Municipal Economic and Information Commission that the relevant departments intend to submit detailed smart car development planning proposals to the municipal government, and local auto manufacturers have developed intelligent assistance such as automatic parking for no people and mobile APP control. It is expected to be installed on Chongqing's own brand vehicles within next year.
The ultimate goal of a smart car – no driver, how far is it from Chongqing? What is the development status of local smart cars in Chongqing? In the past few days, the Chongqing Evening News reporter conducted a survey of research and development institutions and car companies in many universities in the city.
"At present, the closest to the ordinary people in the function of smart cars is the intelligent application based on the Internet of Vehicles." Talking about smart cars, Yi Gang, director of the Institute of Intelligence and Software Research Institute of Changan Automobile Engineering Research Institute, said.
Yi Gang introduced that Changan’s own mobile app (mobile app) has entered the final stage of the experiment. Facing a vehicle equipped with the APP control module, Yi Gang used the mobile phone APP to complete the unlocking, ignition, and air conditioning operations a few meters away from the car. He stressed that it is impossible to drive without locking the key after ignition. At this time, the vehicle will be forced to stop and the vehicle will turn off and alarm.
At the same time, the app also provides a remote car search function. If the vehicle that is bound to the APP is registered and stolen, it can be remotely located through the mobile phone.
Yi Gang said that this mobile phone APP can be seen in a few joint venture brands, such as General Anji Star, but in its own brand, Changan is in the forefront. Soon after, the APP control function will be installed in the latest models of Changan, and some of the recently shipped models have already reserved the installation interface of the system, which is convenient for future upgrades.
"In the Car Multimedia control, we will also have new actions." Yi Gang said that due to the development of smart phones, car multimedia control has become very tasteless, such as navigation systems, car navigation can not be updated online, low practical value, Car entertainment such as DVDs and CDs are also largely out of date.
How to make the mobile phone and car system perfectly linked? Apple and Google have recently launched a car-based multimedia system interface. At present, Changan Automobile has developed a set of vehicle-based multimedia mapping interface based on mobile phone Android system through technology introduction and cooperation.
Yi Gang demonstrated that the mobile phone is connected to the car multimedia through a USB cable, and the HD display in the car can display all the contents of the mobile phone, and use the mobile phone network and the mobile phone APP to realize functions such as playing video, music, navigation and the like.
Compared with smart applications to improve the driving experience, Yi Gang said that the assisted driving function is another important part of the car's intelligence, except for the functions of the lane-assisted, parking assist, 360-degree panoramic scanning and other components that have been assembled on the production models. Advanced functions such as automatic parking and short-range interconnection have also been achieved.
Yi Gang said that Changan Automobile General Engineering Institute will launch an automatic parking system in the near future. The driver can remotely park the car outside the car. This is extremely rare in the production car of the self-owned brand.
He introduced that through the system, after the driver scans the selected parking space, he can leave the vehicle and use the remote control key to control the vehicle to enter the parking space. "If there is someone behind, the car will stop actively." Changan's automatic parking technology is It has been jointly developed with famous domestic universities such as Repost, Tsinghua, Tongji, etc., using international big brands such as Bosch hardware for improved integration design, and its functions have been relatively complete. It is expected that it will be assembled on Changan production models within next year.
“We are also stepping up research and development of DSRC (Special Short-Range Communication Technology) technology.” Yi Gang said that this technology is an efficient wireless communication technology that enables short-range network connection between the vehicle and the vehicle. The running state of the vehicle outside the field of view plays a role in prompting the safety distance of the vehicle, warning traffic accidents ahead, and avoiding congested road sections.
According to Yi Gang, there are media reports that the US Highway Traffic Safety Administration announced last year that it will formulate measures to force the newly-built vehicles in the United States to force the installation of DSRC-based vehicle-to-vehicle communication systems to reduce the incidence of traffic accidents. According to the requirements of the National 863 Program, Changan Automobile R&D Department began to undertake research and development of DSRC technology in 2012, and has achieved good results. “It is expected that vehicle-to-vehicle interconnection within 500 to 1000 meters can be achieved.”
Who is responsible for the driverless accident?
Yi Gang believes that the complex road environment is the most difficult problem for smart cars at present, and the development of car networking will become the source of unmanned auxiliary information. At the same time, in addition to technological innovation, the improvement of relevant laws and regulations is also an important part of automotive intelligence. For example, if an unmanned car has an accident, is the responsibility of the owner or the manufacturer of the intelligent system? From the ethics and regulations, there is a need for new norms and interpretations.
Smart cars may be cheaper "Compared to traditional cars, the sales and profit models of smart cars will also undergo subversive changes." Chen Jiangtao, head of the network car maintenance platform, believes that the sales and maintenance of intelligent cars will be more intelligent. Based on the integrated network environment, it is very likely that the car will save a lot of intermediate links and use the Internet or even the car network to complete sales. At the same time, sellers are likely to purchase smart cars at very low prices, while car companies are mass-harvesting car-connected end users, providing intelligent experiences and services, and linking with more nearby service providers to generate profits.
Unmanned driving in the ultimate stage “Unmanned driving control is not the moon in the water, the flowers in the mirror.” Professor Wang Jin, deputy director of the Chongqing Key Laboratory of Computational Intelligence of Chongqing University of Posts and Telecommunications, said. Intelligent driving technology started earlier in foreign countries, and domestic universities such as Beijing Institute of Technology and Tsinghua University have also formed comparative research results.
"At this stage, driverless, accurately speaking, is still assisted driving." Wang Jin believes that the first stage of assisted driving is, for example, lane offset reminder, automatic parking, adaptive cruise control, etc. This is currently a lot of car companies. Technology that has been implemented. The second stage is fixed-point automatic driving, which enables unmanned driving from point A to point B on a road with simple road conditions such as highways.
In actual operation, this technology can not be completely separated from manual operation. Taking Chongqing to Chengdu as an example, when the vehicle is driving, the vehicle selection road is wrong, or the emergency system cannot be identified, and the driver still needs to brake and correct the direction. Wait for manual intervention.
Wang Jin said that the current highest technical level in the country is expected to require no less than 10 manual interventions in Chengdu to complete in Chongqing. In any road condition, the unmanned technology in any area cannot be realized in a short time.
Wang Jin said that the National Natural Science Foundation of China will organize the China Smart Car Future Challenge every year, which basically represents the most advanced research results of domestic smart cars. At present, no unmanned vehicles developed by local universities and research institutions in Chongqing can participate in this. Event.
However, up to now, Chongqing University of Posts and Telecommunications has invested more than 5 million yuan in research and development funds for the development of new technologies for smart cars. The 1:12 model car produced by Wang Jin’s team can realize multi-vehicle driverless driving on the model road and won the first place in the national mini-sports competition.
Wang Jin also revealed that Chongqing University of Posts and Telecommunications and Changan Automobile have begun to cooperate in the development of a driverless real car. A real car model based on Changan Yidong Automobile has been able to drive unmanned on campus for a short distance.
"It is too early to say that no one is driving, and the automobile industry generally believes that it will be in 2025." Yi Gang said.
Status of smart cars abroad At the North American International Auto Show, which was unveiled last week, and the International Consumer Electronics Show (CES), which ended recently, many automakers launched smart car related products.
GM CEO Mary Bora said that next year, the new Cadillac model will provide users with semi-automatic driving technology, namely the super cruise system.
The super-cruise system brings a new driving experience, such as the vehicle automatically driving according to the lane after the steering wheel is released, controlling the speed or braking in certain road conditions. The system uses radar, ultrasonic sensors, GPS map data and cameras to collect information to help the vehicle turn and maintain the vehicle in a straight line in the lane. The radar data is also used to maintain a safe distance from the vehicle in front, and if necessary the vehicle will start braking until it is fully braked.
According to Cai Che, chairman of Daimler and president of Mercedes-Benz Automotive Group, the Mercedes-Benz autopilot prototype is equipped with a touch screen and a floating center console that allows any passenger to control the car. This driverless car features a subversive cockpit design with a 2+2 seat. The front two seats can be rotated 180 degrees backwards in the unmanned mode, allowing front and rear passengers to communicate face-to-face with zero obstacles.
Another highlight of this driverless car is the continuous information interaction between the car, the passengers inside the car and the environment outside the car. Six display screens are perfectly integrated into the in-vehicle dashboard, rear panel and door trim, so that every passenger can keep track of the vehicle information and interact with the vehicle. There is no control button up and down the car. Passengers can intuitively interact with connected cars through gestures, eye tracking or touch screens, just by simply waving or turning the eye to control the car's every move.
Rush Nair, Ford's chief technology officer and global product director, said at CES that he expects some automakers to launch fully-automated models within five years without any manual intervention while driving. Nair said that Ford's early autopilots will focus on specific areas, those that already have HD maps and are good for sensor work.
According to media reports, global self-driving cars will reach 11.8 million in 2035. By 2050, almost all cars will become autonomous.
“The current industry consensus is that smart cars are almost equivalent to assisted driving and driverless cars.” Wang Jin, deputy director of Chongqing Key Laboratory of Intelligent Computing in Posts and Telecommunications, said that using various technological means to replace the driver’s control of the car is the car. Intelligent.
"Smart cars should be a broad concept, including various technologies such as car networking to enhance the driving experience." Chen Jiangtao, the head of the network car maintenance platform, believes that the car enters the ECU to control the throttle from the carburetor era, which is actually a kind of The embodiment of intelligence is the first stage. At present, the constant speed cruise, reversing assistance, ESP and other functions commonly used in vehicles should be regarded as the second stage of intelligence. Then the more popular assisted driving technologies, such as automatic parking, adaptive cruise control, and networked and intelligent car control, should belong to the third stage, and the final completely unmanned driver should belong to the smart car. The ultimate stage.
