Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific examples, and the purpose and effect of the present invention will become more obvious.

[0019] figure 1 It is a braking system block diagram of an example of the braking method of the present invention that can recognize the driver's braking intention. The system includes: a sensor unit 10, an electric control unit 20 and an EHB actuator. The sensor unit 10 includes an accelerator pedal position sensor 101 and a brake pedal position sensor 102 . The electronic control unit 20 is responsible for processing the collected signals and generating braking intention signals according to the fuzzy reasoning algorithm.

[0020] Among them, the accelerator pedal position sensor 101 and the brake pedal position sensor 102 can adopt the TBQ-9 product of Nanjing Aolian Automotive Electronics Co., Ltd., and the electronic control unit 20 and EHB actuator can adopt the ...

Abstract

The invention discloses a brake method capable of distinguishing the brake intention of a driver, comprising: an electric control unit receives information input by a brake pedal position sensor, an accelerator pedal position sensor and the like, then fuzzy reasoning algorithm is used for distinguishing the brake intention of the driver, finally, a corresponding brake intention control signal can be generated; the brake intention control signal can be used for controlling the action of an EHB executing mechanism, thus fully exerting the advantages of the EHB system, accurately reflecting the intention of the driver in time in case of emergency, reducing brake reaction time, shortening braking length and optimizing the stability of vehicle.

Description

technical field [0001] The present invention relates to a braking method used in an EHB (Electronic Hydraulic Brake, electronic hydraulic braking) system, in particular to a braking method capable of identifying a driver's braking intention. Background technique [0002] At present, almost all automobile braking systems use hydraulic or pneumatic braking, and the liquid or gas pressure is transmitted to the wheels through the brake master cylinder and a series of pipeline components. When the brake pedal is stepped on, the pedal pushes the piston in the brake master cylinder through the push rod, so that the brake fluid generates pressure and is transmitted to the wheel brake through the pipeline. Its essence is to amplify the force applied by the driver on the brake pedal by a certain multiple, and act on the wheel cylinder to generate braking force. Therefore, for weaker drivers, the problem of insufficient braking force may occur, and in an emergency, accidents may also ...
