1. The development process of driverless cars in China

China’s self-developed unmanned vehicle-the Hongqi HQ3 self-driving vehicle independently developed by the National University of Defense Technology. On July 14, 2011, it completed the first high-speed full-range unmanned driving experiment from Changsha to Wuhan for the first time, creating China’s independent research and development. The new record of autonomous driving of unmanned vehicles in general traffic conditions indicates that China’s unmanned vehicles have achieved new technological breakthroughs in environmental recognition, intelligent behavior decision-making and control.

The Hongqi HQ3 unmanned vehicle was independently developed by the National University of Defense Technology. In mid-July 2011, it departed from the Changsha Yangzichong toll gate of the Beijing-Zhuhai Expressway and arrived in Wuhan in 3 hours and 22 minutes, with a total distance of 286 kilometers. In the experiment, unmanned vehicles overtook 67 times, encountering complicated weather, foggy parts of the road, and rain in Xianning.

The computer system controls the speed and direction of the vehicle during the entire Hongqi HQ3. The maximum speed set by the system is 110 kilometers per hour. During the experiment, the measured average speed of the entire autonomous driving was 87 kilometers per hour. According to the National University of Defense Technology, the distance for the vehicle to conduct manual intervention under special circumstances is only 2.24 kilometers, which is only 0.78% of the total autonomous driving mileage.

Starting in the late 1980s, under the leadership of Professor He Hangen, an unmanned vehicle with a speed of 76 kilometers per hour was successfully developed in 2001. In 2003, China’s first high-speed driverless car with a maximum speed of 170 kilometers per hour was successfully developed; developed in 2006 The new generation of unmanned Hongqi HQ3 has achieved breakthroughs in reliability and miniaturization. The Hongqi HQ3 unmanned vehicle experiment has successfully created a new record for autonomous driving of China’s self-developed unmanned vehicles under complex traffic conditions, which indicates that China has reached the world’s advanced level in this field.

By 2020, drivers will no longer have to worry about rear-end collisions. “The driverless car will detect the distance to the vehicle in front through its own radar system. If it is too close to the vehicle in front, the car will automatically brake.”

By 2030, drivers can basically control only the steering wheel or only step on the accelerator and brakes under more complicated road conditions, because semi-autonomous driving technology will be applied to most vehicles. At that time, the car will automatically set the route or automatically perform the accelerator and brake. Brake coordination.

According to the National Natural Science Foundation of China, China’s self-developed self-driving cars will be tested from Beijing to Tianjin in 2013 and from Beijing to Shenzhen in 2015.

2. How to manage unmanned driving operation data

The United States has stipulated a “reporting system” in the “Federal Autonomous Vehicle Policy” to monitor the performance of autonomous driving technology during the testing process and to help NHTSA perform its safety oversight duties. The purpose of the system is more to “supervise” the production and production of driverless cars. However, the editor believes that driverless cars with artificial intelligence as the core are new to drivers, manufacturers and government regulators. Regulators should not only supervise the safety of driverless cars, but also need to strengthen communication and cooperation with manufacturers to help them continuously improve the manufacturing technology of driverless cars. Therefore, my country’s driverless car operation report system not only needs to report vehicle information to ensure the realization of supervision, but also needs to report vehicle faults and problems.

In short, the self-driving car reporting system should include three types of content. The first is the regular reporting system. According to the law, car owners will report the status of driverless cars at specific times each year, such as the convenience and responsiveness of driverless cars to switch freely, the ability of autonomous driving under special road conditions, and their satisfaction with autonomous driving. Its problems. The second is the vehicle breakdown report. It is not yet known what failures will happen to driverless cars in the future and how to improve them. Through the car breakdown report system, car problems can be reported in time, providing certain guidance for driverless technology. The third type is accident reports. In fact, the road traffic department has statistics on the incidence of vehicle accidents every year, but the more important purpose of counting the number of unmanned vehicle accidents is to judge the safety of autonomous driving when the driver is not involved in driving. Therefore, after a traffic accident occurs in an unmanned vehicle, the driving object (automatic driving or manual driving), the cause of the accident, and the consequences of the accident should be reported within a certain period of time.
