The Research of Automobile Automatic Stabilizer Bar Control System and Test Platform

In connection with the problems that the automobile passive stabilizer bar can't reflect the road conditions in real time and it is difficult to simultaneously meet the requirements of ride comfort and manipulation stability, this paper describes a kind of control system and test platform of the automobile automatic stabilizer bar. The control system uses speed sensor, steering angle sensor, roll angle sensor, lateral acceleration sensor and displacement sensor to simulate a variety of vehicle's real driving conditions in the laboratory environment. According to the formulated control strategy, the microcontroller will send different instructions to make the executive mechanism act reasonably and in time. Then the test platform is established in the laboratory environment by the method of semi-physical simulation. The system can be designed according to the different needs of the vehicle and ensures the vehicle's safety and comfort to the maximum
