The invention relates to an electronic parking system of an electric automobile and the automobile. The electronic parking system of the electric automobile comprises a low-voltage storage battery, a direct-current-to-direct-current controller, a main controller, a first area controller, a second area controller, a first caliper motor and a second caliper motor. The first area controller and the second area controller both have the parking function, after a braking request signal sent by the main controller is received, the first caliper motor and the second caliper motor can be driven to work, kinetic energy is provided for parking braking, and the requirements for automobile parking and low-speed parking are met. The low-voltage storage battery and the DC-to-DC controller can supply power to the first area controller and the second area controller, and when the low-voltage storage battery breaks down, the DC-to-DC controller can supply power to the first area controller and the second area controller, so that the first caliper motor and the second caliper motor can work normally. The reliability of the braking function is guaranteed, and the safety problem in the parking process is prevented.
本发明涉及一种电动汽车电子驻车系统及汽车,电动汽车电子驻车系统包括低压蓄电池、直流转直流控制器、主控制器、第一区域控制器、第二区域控制器、第一卡钳电机与第二卡钳电机。第一区域控制器与第二区域控制器都具有驻车功能,在接收到主控制器发送的制动请求信号后,能够驱动第一卡钳电机工作与第二卡钳电机工作,以为驻车制动提供动能,实现汽车驻车、低速泊车需求。低压蓄电池与直流转直流控制器均可以为第一区域控制器与第二区域控制器供电,当低压蓄电池出现故障时,可通过直流转直流控制器为第一区域控制器与第二区域控制器供电,使第一卡钳电机与第二卡钳电机可以正常工作,以保证形成制动功能的可靠性,防止驻车过程中出现安全性问题。
