An electric vehicle electronic parking brake system and vehicle

Abstract

The application relates to an electric vehicle electronic parking system and a vehicle, wherein the electric vehicle electronic parking system comprises a low-voltage storage battery, a DC-DC 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 a parking function, and after receiving a brake request signal sent by the main controller, the first area controller and the second area controller can drive the first caliper motor and the second caliper motor to work to provide kinetic energy for parking brake, so that the vehicle parking and low-speed parking requirements can be realized. The low-voltage storage battery and the DC-DC controller can both supply power to the first area controller and the second area controller, when the low-voltage storage battery fails, the first area controller and the second area controller can be supplied with power through the DC-DC controller, so that the first caliper motor and the second caliper motor can normally work, the reliability of the brake function is ensured, and safety problems in the parking process are prevented.
