Abstract

The invention discloses a vehicle anti-lock control method and system based on driver intention recognition, and the method comprises the steps: obtaining the hydraulic information of a vehicle braking system in real time, and calculating the hydraulic pressurization rate of the vehicle braking system within a preset time period according to the hydraulic information; if the hydraulic pressurization rate exceeds a first preset threshold value, judging that a driver needs emergency braking, and then performing additional pressurization on a wheel brake cylinder; and when it is detected that the vehicle slip rate exceeds the preset slip rate threshold value, triggering the vehicle anti-lock function. By implementing the method, the problem that the anti-lock function cannot be triggered in emergency due to insufficient strength of a driver can be solved, and the vehicle use safety is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle anti-lock braking systems, in particular to a vehicle anti-lock braking control method and system based on driver intention recognition. Background technique [0002] At present, the brake system uses the principle of pedal lever and the form of air pressure difference or motor assist. After the driver's brake pedal force is amplified several times, the input is converted into hydraulic pressure by the brake master cylinder, and then the brake is controlled by the brake cylinder. The dynamic hydraulic pressure is converted into braking force and acts on the wheels. Between the brake master cylinder and the brake cylinder, a hydraulic control unit is connected in series through the brake pipeline. The hydraulic control unit realizes the anti-lock braking control function through an algorithm by monitoring the changes in the wheel speeds of the four wheels. This technology requires the driver to st...
