Abstract

The invention discloses an electric vacuum pump controlling method and device. The electric vacuum pump controlling device comprises a vehicle control unit, a vehicle speed sensor, a brake light, a trouble light, a vacuum tank, a vacuum pump, a vacuum booster, a vacuum sensor arranged inside the vacuum tank, a brake switch connected with a brake pedal, a key switch, and a wheel speed sensor used for detecting the rotating speed of a vehicle tire. The vehicle control unit is electrically connected with the vehicle speed sensor, the brake light, the trouble light, the vacuum pump, the vacuum sensor, the brake switch, the key switch and the wheel speed sensor. The vacuum tank communicates with the vacuum pump and the vacuum booster through vacuum pipelines. The electric vacuum pump controlling device and method have the characteristics that power can be accurately controlled, braking force is high, electric power is saved and cost is low.

Description

technical field [0001] The invention relates to the technical field of electric vacuum pump control strategies, in particular to an electric vacuum pump control method and control device that can be precisely controlled, have strong braking force, save power, and have low cost. Background technique [0002] The electric vacuum pump is a part of the vacuum boosting system of the car. The vacuum boosting system includes: electric vacuum pump, vacuum tank, vacuum booster, vacuum pipeline and other parts. Among them, the electric vacuum pump is responsible for extracting vacuum; the vacuum tank is responsible for storing the vacuum drawn by the electric vacuum pump and collecting The vacuum degree signal controls the direction of the vacuum; the vacuum booster is responsible for providing boost to the driver, so that the driver can provide sufficient braking strength with a small pedal force, and this process consumes vacuum. [0003] Therefore, whether the control strategy of t...
