Abstract

The invention relates to the technical field of automobile braking, in particular to an electronic parking system, a vehicle comprising the same and a control method. The invention aims to solve the problem that an existing electronic parking system is low in safety. In order to achieve the purpose, the electronic parking system comprises a primary parking controller and a secondary parking controller, wherein the primary parking controller is at least connected to a first wheel brake for receiving a braking command and controlling the first wheel brake to act based on the braking command; andthe secondary parking controller is at least connected to a second wheel brake for receiving the braking command and controlling the second wheel brake to act based on the braking command and a stateinformation of the primary parking controller. By arranging two electronic controllers redundantly, the electronic parking system can improve the safety performance of the vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to an electronic parking system, a vehicle including the electronic parking system and a control method. Background technique [0002] Electrical Parking Brake (EPB for short) is a technology that realizes parking brake through electronic control. In the current traditional cars, the electronic parking system has gradually become the mainstream due to its advantages of convenient operation, reliability, and small space occupation of the car. Generally, the electronic parking main system adopts two structural forms: cable-type electronic parking system and caliper-integrated electronic parking system. Both structural forms of electronic parking systems realize vehicle parking by braking the rear wheels separately. rear braking. [0003] With the continuous development of automatic driving technology, driving safety is always an inevitable topic. In order to realize the h...
