Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a novel braking device and method for an electric automobile. Background technique [0002] The braking of the traditional braking system is realized by the driver applying force on the brake pedal, which is amplified and converted into hydraulic pressure by the vacuum booster system, and acts on the brake to achieve braking. The vacuum booster system currently used in automobiles is composed of a vacuum booster with a brake master cylinder, a vacuum tank, a vacuum pump, and a vacuum tube. The vacuum booster with a brake master cylinder uses the pressure difference between the vacuum and the atmosphere to apply pressure on the driver The braking force on the plate is amplified, and this force is transmitted to the brake master cylinder to establish hydraulic pressure to realize the transformation from pedal force to hydraulic pressure, and the brake f...
