Abstract: Abstract： For the characteristics of full electric propulsion on electric vehicle, a novel brakebywire unit， called directdrive electrohydraulic brake unit， was designed to improve the braking performance of electric vehicles based on an electromagnetic linear actuator. A prototype was modified and completed based on a certain type of hydraulic brake unit after the structure and principle of this novel brake unit was described in detail. Then, a braking force controller and a power driver were established based on the digital signal processor TMS320F2812, and a doubleloop antidisturb algorithm was designed to regulate the braking force. The experiment results show that the response time of this brake unit is very short and the brake force is able to be accurately regulated, showing that this brake unit has a good application prospect.
