Embodiment Construction

[0028] The invention utilizes a humidity sensor and a pressure sensor to detect whether the car is wading, the brake pedal position sensor judges whether the brake is being applied, and transmits the detection result to the body controller, which controls whether the direct-acting solenoid valve is applying the brake. , and use the reminder device to remind the driver when braking automatically.

[0029] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited.

[0030] The brake performance quick recovery system after the automobile wading provided by the present invention has the following structure: Figure 1-Figure 2 As shown, it includes a humidity sensor 1, a pressure sensor 2, a vehicle body controller 3, an in-car reminder device 4, a brake pedal position sensor 6 and a direct-acting solenoid valve 8, wherein: the humidity sensor 1 and the pressure sensor 2 are all moun...

Abstract

The invention discloses a braking efficiency rapid recovery system after an automobile wades. The braking efficiency rapid recovery system comprises a humidity sensor (1), a pressure sensor (2), an automobile body controller (3), an intra-automobile reminding device (4), a brake pedal position sensor (6) and a direct acting electromagnetic valve (8). The humidity sensor and the pressure sensor are both installed on the inner side of a wheel. The intra-automobile reminding device is installed on a dashboard. The brake pedal position sensor is installed on a connecting rod at the bottom of a brake pedal. The direct acting electromagnetic valve is installed below the brake pedal and connected with the brake pedal through the connecting rod. According to the braking efficiency rapid recovery system after the automobile wades, the braking safety problem after the automobile wades is solved, the braking efficiency can be automatically recovered when the automobile braking safety application is improved, the operating quantity for a driver is decreased, and the high reliability and feasibility are achieved.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a system for quickly recovering braking performance of an automobile after wading through water. Background technique [0002] Car braking is to use external force to press the brake pads and brake drums (discs) of the car together, and use the friction between the two to convert the kinetic energy of the car into heat energy and consume it, thereby realizing the braking of the car. Since there is a certain gap between the brake pad and the brake drum (disc), if the car is wading, water and sediment will enter the gap, causing the brake pad and the brake drum (disc) The friction coefficient between the disc brakes decreases, which in turn reduces the braking performance of the car. Although the disc brakes have better water resistance and can recover the braking performance after several braking, there is a problem before the braking performance is restored. When emergency braking ...
