The invention discloses an electronic parking braking system for an electric vehicle, which comprises a first parking braking mechanism, a second parking braking mechanism and a control module, and the control module controls the first parking braking mechanism and the second parking braking mechanism to execute parking braking action through division of work of a first control unit and a second control unit. By arranging the first parking braking mechanism and the second parking braking mechanism, two parking braking mechanisms based on the EPB can be achieved, one parking braking mechanism can play a role of the EPB, and the other parking braking mechanism can replace a P-gear parking function to form redundancy with the parking braking mechanism playing the EPB function. Therefore, sufficient guarantee is provided for parking braking of the electric automobile, and the electric automobile has good safety performance. According to the invention, the manufacturing cost and the maintenance cost of the motor assembly used by the electric automobile can be reduced. The invention is widely applied to the technical field of automobiles.
本发明公开了一种用于电动汽车的电子驻车制动系统,包括第一驻车制动机构、第二驻车制动机构和控制模块,控制模块通过第一控制单元和第二控制单元的分工,控制第一驻车制动机构和第二驻车制动机构执行驻车制动动作。本发明通过设置第一驻车制动机构和第二驻车制动机构,可以实现两个基于EPB的驻车制动机构,其中一个驻车制动机构可以起到EPB本身的作用,另一个驻车制动机构可以代替P档驻车功能而与起到EPB功能的驻车制动机构形成冗余,从而为电动汽车的驻车制动提供充分的保障,使得电动汽车具有良好的安全性能;本发明可以降低电动汽车所使用的电机总成的制造成本和维护成本。本发明广泛应用于汽车技术领域。
