Abstract

The invention relates to an electrical parking system capable of meeting automatic driving requirement. The electrical parking system is characterized by comprising an automatic driving control module, an electrical parking controller, an electrical parking actuator, an electrical parking switch, a brake controller and a brake actuator, wherein a CAN signal communication terminal of the automatic driving control module is connected with a CAN signal communication terminal of the electrical parking controller and a CAN signal communication terminal of the brake controller through a CAN bus; a parking actuating hardwire interface of the electrical parking controller is connected with a hardwire interface of the electrical parking actuator through a hardwire; a parking switch hardwire interface of the electrical parking controller is connected with a hardwire interface of the electrical parking switch through a hardwire; and a brake actuating hardwire interface of the brake controller is connected with a hardwire interface of the brake actuator through a hardwire. Through the adoption of the electrical parking system disclosed by the invention, reliable parking and release functions of an EPB on an automatic driving vehicle are achieved.

Description

technical field [0001] The invention relates to the technical field of automobile automatic driving, in particular to an electronic parking system and a parking method that meet the requirements of automatic driving. Background technique [0002] Autopilot technology has gone through decades of development from its inception to the present. Many parts of self-driving vehicles follow traditional vehicles, and the electronic parking system is one of them. [0003] The parking and release functions of traditional automotive electronic parking systems require the driver's manual operation to be realized. Its control principle is as figure 1 Shown: [0004] The driver toggles the electronic parking switch, and then transmits parking and release signals to the electronic parking controller through the first hard line, and the electronic parking controller realizes the control of the electronic parking actuator to complete the parking and release actions. [0005] At present, s...
