Abstract

The invention provides an electric vacuum pump control circuit of an electric vehicle, which belongs to the technical field of vehicles and solves the problem of huge energy consumption due to continuous work of an electric vacuum pump in the traditional vehicle. The electric vacuum pump control circuit of the electric vehicle comprises a storage battery, an ignition switch and an electric vacuumpump which are sequentially connected in series and form a loop, wherein a relay is also connected in series between the ignition switch and the electric vacuum pump; the control circuit is also provided with a vehicle speed sensor; the vehicle speed sensor and the relay are both connected with a vehicle controller of the vehicle; and the vehicle speed sensor transmits a collected vehicle speed signal to the vehicle controller and controls the closing or the opening of the relay after the signal is processed by the vehicle controller. The electric vacuum pump control circuit of the electric vehicle can control the electric vacuum pump to stop working if unnecessary and has the advantages of low energy consumption, long service life and high safety and effectiveness during use.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to an electric vacuum pump control circuit of an electric automobile. Background technique [0002] At present, with the continuous consumption of various energy sources, the problem of energy crisis is becoming more and more serious. All technical fields need to develop new energy sources to replace the current main energy consumption. In the field of automobiles, pure electric vehicles are a representative of new energy use. In order to meet the braking requirements of electric vehicles, compared with the traditional internal combustion engine vehicle braking system vacuum booster, the engine intake manifold is used as a vacuum source. Most electric vehicles use electric vacuum pumps to work continuously to draw a vacuum. In this way, the driver can easily control the brake pedal of the car to achieve braking by relying on the help of the electric vacuum pump. [0003] Most of ...
