Abstract

The invention discloses an electric auxiliary brake system of an electric automobile, through which sufficient power can be provided to the electric automobile, the brake performance of the electric automobile is improved, the safety performance of the electric automobile is improved and the defects in the prior art are overcome. The electric auxiliary brake system of the electric automobile comprises a brake main cylinder, a brake pedal, a vacuum booster, a vacuum pump and a vacuum boosting controller, wherein the vacuum booster is respectively connected with the brake pedal and the brake main cylinder; a vacuum tank is arranged between the vacuum booster and the vacuum pump; the vacuum booster is connected with the vacuum tank through a vacuum pipeline; the vacuum tank is connected with the vacuum pump through a vacuum pipeline; a vacuum check valve is arranged on the vacuum pipeline which connects the vacuum booster with the vacuum tank; a vacuum pressure detection device is arranged on the vacuum tank; and the vacuum pressure detection device and the vacuum pump are respectively connected with the vacuum boosting controller.

Description

technical field [0001] The invention relates to the technical field of electric vehicle braking, in particular to an electric auxiliary braking system for electric vehicles. Background technique [0002] The booster is a related device for the vehicle to control the vehicle with the help of compressed air, high-pressure oil, etc., in order to achieve the purpose of lightness of use. In the automotive braking system, it is used to reduce the driver's work intensity. The booster is installed between the brake pedal and the brake master cylinder. The booster is divided into a vacuum booster and a hydraulic booster. The vacuum booster relies on the negative pressure generated by the engine intake as the power source, so that the front , The air pressure difference in the rear chamber increases, so that the force acting on the brake master cylinder is greatly increased compared with the force of the driver stepping on the brake pedal, and the purpose of vacuum boosting is achieve...
