My car anti-lock system independent research breakthrough

This newspaper (intern Chen Shiyan) was written by the doctoral student of Tsinghua University, Yu Liangyao, and the article "Evaluation and Test of Hydraulic System Performance in Anti-lock Braking System". Through simulation and test data, the hydraulic actuator was discussed. The key factors affecting the control effect of the anti-lock braking system (ABS) are presented. The key evaluation parameters of the hydraulic system are put forward, and the quantitative parameter values ​​are given. It provides an important basis for the matching of the ABS system and the vehicle braking system. . The study was published in the recently published Journal of Mechanical Engineering.

According to relevant sources, China's auto industry is developing rapidly, but it is slow to develop in the supply of key automotive electronic control systems. As an important component of vehicle dynamics control, ABS can provide higher braking strength and maintain good steering capability during emergency braking through mechatronic design. It has become a passenger car and large commercial vehicle. Essential safety device.

According to reports, the National Natural Science Foundation of China funded a project on the active safety of automobiles for the first time in 2002. “Research on the control method of anti-lock braking system based on brake dissipated power”, the project has now obtained the second of the fund. Round funding. From January 2002 to December 2004, under the auspices of the Natural Science Foundation, the research team successfully completed the development of ABS with independent intellectual property rights, including the most important electronic controllers and hydraulic actuators, thus breaking foreign countries. The company's monopoly. The project successfully achieved large-scale industrialization in the second half of 2004. This is the first time in the domestic key automotive electronic control system. The project also won the highest honor in the automotive field in 2005—the Automotive Industry Science and Technology Progress Award And Other awards.

Since January 2006, the Natural Science Foundation has re-funded the project “Research on Vehicle Dynamics Control Method Based on Driver's Driving Intention Recognition”. Based on the results of the original ABS research, we continue to study the vehicle dynamics control more extensively. The field, including Traction Control System (TCS), Active Yaw Control (AYC), is finally integrated into the Dynamic Stability Control System (DSC, also known as ESP).
