Abstract: The electronic control brake technology for unmanned driving is researched based on a 4×4 manned light tactical wheeled vehicle. An electropneumatic brake system is designed according to the structure and characteristics of the original vehicle air brake, which realizes an electronic control brake function in unmanned driving mode, and reserves the manual brake function in manual driving mode. The two modes can be switched freely. The control characteristics of solenoid valve, vehicle rolling resistance coefficient on different roads, and the relationship among vehicle deceleration, speed and control input of electronic control brake are identified through vehicle test. The test results show that the electropneumatic brake system can rapidly and accurately respond to the braking request, and the user can flexibly switch between manual braking and electronic-controlled braking. The electropneumatic brake system can be used for the commercial vehicles.
