Abstract

The invention provides a vacuum pump control system for an electric automobile. The vacuum pump control system comprises a vacuum pump controller, and a vacuum pump, a pressure sensor, a brake switch, an instrument display and a vehicle control unit which are electrically connected with the vacuum pump controller respectively, wherein the pressure sensor is arranged at an air outlet of a vacuum air tank and is used for detecting air pressure in the vacuum air tank; the brake switch is connected with a brake pedal, and is switched on to transmit a brake signal to the vacuum pump controller; the instrument display is used for outputting a fault signal transmitted by the vacuum pump controller; the vehicle control unit is used for regulating the running condition of the electric automobile according to the pressure condition of the vacuum pump under the control of the vacuum pump controller. The invention also provides a vacuum pump control method for an electric automobile.

Description

Technical field [0001] The invention relates to an automobile control system and a control method, in particular to an electric automobile vacuum pump control system and control method. Background technique [0002] With the increasing awareness of environmental protection, traditional fuel vehicles are now gradually being replaced by new electric vehicles. The traditional electric vehicle vacuum brake booster system is composed of a pressure switch, a vacuum pump controller and a vacuum pump. This system does not have real-time control and related fault diagnosis functions, such as: air leakage, broken motor, broken sensor and other faults, which cause the car to be on the trip Drivers cannot monitor the conditions of the vacuum brake control system in real time, and unfavorable things occur, which is not conducive to the development and promotion of electric vehicles. So in order to achieve this goal, we have developed an electric vehicle vacuum brake booster control system an...
