Electric parking and braking device

Abstract

The electric brake apparatus includes one executing mechanism for braking or brake off; one control module includes one signal acquiring circuit to acquire at least signals of brake switch, engine rotation speed, automobile speed, gear box setting and ignition lock setting, and one control circuit to judge based on the acquired signals and to send command for controlling the executing mechanism; and one emergency release assembly to release the braking state of the brake apparatus in case of self abnormality and incapability of braking. The electric brake apparatus is superior to available manual brake apparatus.

Description

technical field The invention relates to an electric parking brake device, in particular to an automobile electric parking brake device. Background technique At present, the vast majority of automobile parking brake devices are manual parking brake devices. The manual parking brake device has the following shortcomings: 1. The driver needs to manually operate each work, which is cumbersome to operate. 2. When parking on a slope with a large angle, the operation is laborious, parking is difficult, and it is often difficult to obtain a large enough braking force To ensure that the car parks reliably, there are potential safety hazards; 3. Regardless of whether it is flat or slope, the driver is used to pulling the parking brake lever to a larger stroke to ensure that the car can be parked reliably. Under normal circumstances, that is to say, under most conditions of use, the wear and deformation of automobile brake mechanical parts such as brakes and brake cables are increase...
