Abstract

The invention discloses an electrical park brake system, a vehicle and an electrical park brake method. The electrical park brake system comprises a first hard wire interface, a bus interface, a controller and an executor, wherein the first hard wire interface is connected with a parking switch of the vehicle through a first hard wire, and used for acquiring a parking hard wire signal for indicating whether the parking switch is triggered or not; the bus interface is connected with a controller area network of the vehicle, and used for acquiring a bus signal of the controller area network; the controller is used for controlling the executor to execute the operation of electrical park brake operation according to the park hard wire signal and the bus signal; and the executor is used for executing the operation of electrical park brake operation under the control of the controller. According to the electrical park brake system, the vehicle and the electrical park brake method disclosed by the invention, the operation complexity of the vehicle can be reduced.

Description

technical field [0001] The present invention relates to the field of vehicles, and more particularly, to an electronic parking brake system, a vehicle and a method for electronic parking brake. Background technique [0002] Electronic parking brake (Electrical Park Brake, EPB) refers to a technology that integrates temporary braking during driving and long-term braking after parking, and realizes parking braking by electronic control. The EPB system can automatically apply the parking brake after the engine is turned off; it is convenient and reliable to park, and can prevent accidental release; for EPB, the braking force is fixed and will not vary from person to person, and there will be deviation; it can be used in emergency State as a service brake. [0003] In the vehicle, in addition to EPB, there is also a P file (parking file). When the position of the shift control handle is in the P position, the parking lock mechanism will lock the output shaft of the transmissio...
