Abstract

The invention discloses a vehicle braking sensitivity regulating and controlling system which comprises a man-machine interaction device, a brake pedal travel sensor and an electronic brake control module (EBCM). The man-machine interaction device is used for receiving an external input instruction; the brake pedal travel sensor is used for detecting the magnitude and speed of input of a brake pedal; the EBCM comprises an electronic control unit (ECU) and a braking force adjusting unit, and the ECU receives a braking sensitivity adjusting instruction input by the man-computer interaction device, receives input of the brake pedal travel sensor, and then sends a braking sensitivity regulating and controlling instruction; the braking force adjusting unit is used for carrying out delayed pressure building or rapid pressurization operation on a brake pipeline according to the regulating and controlling instruction of the ECU, so that the braking force borne by a brake wheel cylinder is correspondingly changed corresponding to the pressure change of the brake pipeline.

Description

technical field [0001] The invention relates to a brake sensitivity control system of a vehicle, which can dynamically adjust the pressure of the brake system of the vehicle and the rate of change within a certain range according to the input command, so that the same vehicle has different brake sensitivities . Background technique [0002] The brake control systems of road vehicles currently used in the industry mainly include the following three categories: [0003] 1. The brake control system represented by anti-lock braking (ABS) / electronic stability control (ESC) and other functions, such systems generally collect wheel speed signals and body attitude signals (yaw rate signals, lateral Acceleration signal, steering wheel angle signal, etc.), process the wheel speed and body posture, and then compare with the results calculated by the built-in vehicle dynamics model, and adjust the braking force and intervene in the possible wheel lock or vehicle instability. [0004] ...
