Abstract

The invention provides an electronic parking system and an electronic parking redundancy brake control method, which comprises the following steps: a controller is integrated with an electronic parking control unit and an automatic driving control unit which work independently; Two electronic parking brakes respectively arranged on two front wheels of the whole vehicle; Four wheel speed sensors ontwo front wheels and two rear wheels of the vehicle; the electronic parking control unit is connected with an electronic parking switch through a communication line, and the electronic parking brakeand the wheel speed sensor are connected with each other. The automatic driving control unit is connected with the radar controller and the camera controller signals on the whole vehicle. In autopilotmode, the autopilot control unit operates and the electronic parking control unit, electronic parking brake and wheel speed sensor are used as redundant backup braking systems. The electronic parkingcontrol system fully meets the requirement of automatic driving redundant braking backup, and can realize redundant braking in automatic driving mode.

Description

technical field [0001] The invention relates to the technical field of automatic driving of automobiles, in particular to an electronic parking system and an electronic parking redundant braking control method. Background technique [0002] Electronic Parking EPB (Electrical Parking Brake) is a technology that realizes parking brake through electronic control. In the current use of traditional cars, the electronic parking system mainly adopts two structural forms: cable electronic parking and caliper integrated electronic parking. The electronic parking systems of the two structural forms realize parking through independent braking of the rear wheels. Electronic parking only works when parking, and does not actively participate in service braking. [0003] Electronic parking replaces the traditional mechanical hand brake, simplifies the driver's operation, saves the layout space of the center console, and has many advantages and additional functions such as automatic relea...
