[en] With the continuous improvement of world science and technology, vehicle technology has also been greatly developed. Cars bring convenience to people’s travel, and occupy an increasingly high proportion in social life. Automobile plays an important role in the continuous progress of contemporary society and the change of human travel conditions. At the same time, the increasing number of cars also brings many problems: energy consumption and environmental pollution are worsening, traffic accidents are increasing year by year. According to the who survey, the number of casualties caused by traffic accidents in China is gradually increasing. High traffic accidents have caused irreversible losses to social development, people’s lives and property. It has become the development goal to improve the vehicle active safety, control the vehicle to automatically identify the road, drive according to the planned route and reduce the frequency of traffic accidents. In the traditional driving environment, people occupy a dominant position. In the face of complex and changeable traffic environment and a large number of traffic information, it is easy to make mistakes in driving and cause serious traffic accidents. Therefore, it is very important to extricate the driver from the complex and changeable traffic environment and make driving safer. The intelligent vehicle collects the information about the road and the vehicle itself through the sensor, and sends it to the central controller which controls the transverse and longitudinal movement of the electric vehicle. The central controller sends out corresponding instructions to control the horizontal and longitudinal operation of the vehicle according to the control strategy, so as to realize the control of the driving behavior of the vehicle, so that the vehicle can drive safely on the desired track at the expected speed, It can avoid driver fatigue driving behavior and traffic accidents caused by driving technology. Various sensors in the intelligent vehicle can obtain more vehicle information at the same time, and control the vehicle through the controller processing. (paper)

[en] The reform of the mechanism and performance of the internal combustion engine in the traditional automobile industry has always been the main goal in the environmental protection strategy. In recent years, people have proposed experimental technologies for new energy vehicles^[1]. Facts have proved that new energy vehicles have great advantages in energy consumption and environmental pollution prevention. Because of this factor, the space for new energy vehicles to play in the automotive industry is constantly growing. Some emerging automobile-related companies are also working hard to find research and development methods for new energy vehicles. This phenomenon has also led to a sharp increase in the demand for talents after the launch of new energy vehicles. Therefore, the current obsolete automobile research and development profession must undergo transformational development to be able to adapt to the needs of society. The construction of the new energy vehicle test technology specialty is imminent. (paper)

[en] With the increasingly serious problem of energy shortage, new EV (hereinafter referred to as EV) research has become an important research field, which can help alleviate the energy crisis and environmental pollution. New EV is a way based on electric energy as the power source, which is a kind of vehicle with motor as the core. Therefore, the performance of the motor is directly related to the operating efficiency, which requires us to test the motor. Therefore, this paper designs an automatic test method, which can simulate the running time and load of new EVs, which can better ensure the stability under different working conditions. With the development of computer, can bus technology has been applied to various industries, especially in the automotive field. Firstly, this paper analyzes the CAN bus technology of new EVs. Then, this paper analyzes the motor model and file ion battery model. Finally, this paper puts forward the motor test scheme. (paper)
