Embodiment Construction

[0020] Such as figure 1 shown. An electronic parking brake system with AUTOHOLD function, comprising EPB switch 10, EPB controller 14, instrument panel display module 12, AUTOHOLD switch 15, EPB left rear brake caliper 7 and EPB right rear brake caliper composition 8.

[0021] The EPB switch integrates two switches, the parking switch 2 and the release switch 1, and is directly connected to the EPB controller 14 through a wire. The driver can control the parking or release of the electronic parking brake system through the parking switch 2.

[0022] The EPB controller 14 has an interface 11 connected to the CAN bus of the motor vehicle and an acceleration sensor 13 inside. It is used to communicate with other modules of the motor vehicle to obtain the required data.

[0023] The AUTOHOLD switch 15 is directly connected to the EPB controller 14 through wires, and when the driver presses the switch, the EPB controller 14 turns on / off the AUTOHOLD function.

Abstract

The invention discloses an electronic parking brake system with AUTOHOLD function, which comprises an EPB switch, an EPB controller, an instrument panel display module, an AUTOHOLD switch, an EPB left rear brake caliper and an EPB right rear brake caliper. The invention also discloses a brake method corresponding to the system. The system and the method effectively solve the problem that when a driver drives an automobile on a road in a city, the driver needs manually controlling the parking / release frequently, and the problem that the automobile easy slides from a slope due to temperature reduction of a brake disc and reduction of parking brake force.

Description

technical field [0001] The invention relates to the technical field of motor vehicle braking, in particular to an electronic parking braking system with an AUTOHOLD function and a braking method thereof. Background technique [0002] When the vehicle is running on urban roads, it will often encounter situations such as traffic jams and traffic lights, and it is necessary to frequently operate the parking brake lever to park. This brings certain difficulty to the less powerful driver. Increased driver fatigue after long urban driving. Even the new electronic parking brake system requires frequent manipulation of the parking brake switch, which is extremely cumbersome. [0003] In the traditional Pangu type parking brake system, the parking brake system and the service brake system are separated, and the long-term service brake has little effect on the parking brake. For the braking system integrated with parking and driving, after the motor vehicle is braked for a long tim...
