Problems solved by technology
Generally, the brake calipers and brake discs are directly exposed to the outside. When encountering sudden changes in temperature, rain or snow, or when the car passes through deep water on the road, the brake disc will be wet and form a water film on the friction surface. Thereby reducing the friction coefficient between the brake disc and the shoe in the brake caliper, weakening the braking response speed and braking strength of the vehicle, and impairing the braking safety of the vehicle

The invention discloses an automatic water removal device and method of automobile disc brakes based on an electronic stability control system. The device comprises an ESC hydraulic control unit (1), an ESC controller (2), a rainfall sensor (3), a windscreen wiper switch (4), an outside temperature sensor (5) and brake cylinders (6) which are characterized in that the ESC hydraulic control unit (1) is used for controlling the pressure of the brake cylinders (6); the ESC controller (2) is used for controlling the ESC hydraulic control unit (1); the rainfall sensor (3) is used for sensing the rainfall of the external environment; the windscreen wiper switch (4) is used for controlling automobile windscreen wipers to work; the outside temperature sensor (5) is used for sensing the outside temperature and the change rate of the temperature for correcting the estimation value of the brake disc water film thickness; the brake cylinders (6) are used for providing braking force for automobiles and used as an execution device for removing water from the brake disc at the same time. The device utilizes a certain algorithm to operate the actuator mechanism of the electronic stability system to finish the water removal of the automobile disc brake and improve the safety of driving in the rain and snow weather of the automobile.
Description
technical field [0001] The invention relates to a method for controlling an automobile hydraulic disc brake system, in particular to a method for removing water from an automobile disc brake based on an electronic stability control system. Background technique [0002] A large number of hydraulic disc brakes are used in today's automobiles. The disc brakes use high-pressure brake fluid to actuate the brake calipers fixed on the chassis of the car and the brake shoes fixed in the calipers, so that the brake shoes and the wheels The rotating brake disc clamps to generate braking force. Generally, the brake calipers and brake discs are directly exposed to the outside. When encountering sudden changes in temperature, rain or snow, or when the car passes through deep water on the road, the brake disc will be wet and form a water film on the friction surface. Thereby reducing the friction coefficient between the brake disc and the shoe in the brake caliper, weakening the braking ...
