Embodiment Construction

[0033] A method for controlling an electronic parking brake system for a vehicle provided by the present invention includes an electronic parking control unit 1, an inclination sensor 3, and a parking actuator 2. In the first step, the electronic parking control unit 1 detects the ignition Signal 5, parking switch signal 6, gear position signal 7; the second step, the electronic parking control unit 1 detects the signal of the inclination sensor 3; the third step, the electronic parking control unit 1 according to the signal of the inclination sensor 3, Calculate the clamping force corresponding to the parking actuator 2; in the fourth step, the electronic parking control unit 1 sends an instruction to the parking actuator 2; in the fifth step, the parking actuator 2 To start the action, the corresponding calculated clamping force is applied to the brake disc. In the sixth step, when the corresponding clamping force is reached, the parking actuator 2 maintains the clamping for...

Abstract

The invention discloses an EPB for vehicles and a control method. The EPB comprises an electrical park control unit and a park actuating mechanism which are communicated, wherein the electrical park control unit comprises a tilt sensor and a current detection device and is connected with an ignition signal, a park switching signal and a gear signal respectively; and the current detection device comprises a current sensor, and the electrical park control unit calculates the park clamping force through the detected current. According to the technical scheme, the mechanical life of the park actuating mechanism can be prolonged, noise in a parking process of a vehicle can be reduced, and fuel consumption can be reduced; and simultaneously, the production cost is low, the safety, stability and reliability are high, and the like.

Description

technical field [0001] The invention belongs to the technical field of manufacturing electronic parking brake systems for vehicles, and in particular relates to an electronic parking brake system for vehicles and a control method. Vehicles in this patent include but are not limited to automobiles, hybrid vehicles, pure electric vehicles, etc. Background technique [0002] At present, in the field of vehicle brake system manufacturing technology, the application of mechanical control electronics has become more and more extensive, and more and more electronic parking brake systems are appearing in the eyes of consumers. Electronic parking brake system (EPB: Electrical Park Brake) refers to a technology that integrates temporary braking during driving and long-term braking after parking, and realizes parking braking by electronic control. [0003] The electronic parking brake system can calculate the sliding force of the vehicle due to gravity on the slope through its control...
