Abstract

The invention discloses a pure electric vehicle intelligent vacuum pump control system and method based on a whole vehicle CAN framework. The system comprises a vacuum pump controller module which isused for providing the working time of a vacuum pump motor, the vacuum degree of a vacuum tank and the character prompts and indicating lamp prompt signals of a vacuum pump system and controlling thework and stop of a vacuum pump, an instrument module which is used for informing a driver of the information sent by the vacuum pump controller module and a vehicle-mounted remote information processing controller module in the form of characters and indicating lamps, a vehicle control unit module which is used for providing vehicle speed, wheel speed, gears, driving motor torque, vehicle brakingdeceleration signals, vehicle ambient atmospheric pressure and vehicle service time, and the vehicle-mounted remote information processing controller module which is used for recording the vehicle state and the state of the vacuum pump system in real time, carrying out detection and feeding back a detection result to the vacuum pump controller module and a background. The characteristics of a VCU,an instrument and a T-BOX are combined, more comprehensive input is provided for work of the vacuum pump, and the vehicle driving safety is effectively improved.

Description

technical field [0001] The invention relates to a pure electric vehicle vacuum pump control system based on a complete vehicle CAN framework, in particular to a pure electric vehicle intelligent vacuum pump control system and method based on a complete vehicle CAN framework. Background technique [0002] With the rapid development of electric vehicles in the automotive industry, since pure electric vehicles have no engines or hybrid vehicle engines cannot work full-time, the vacuum source of the vehicle braking system needs to be provided by an electronic vacuum pump. Therefore, the vacuum pump system has become an important part of the vehicle electrical system, in which the vacuum pump is directly controlled by the vacuum pump controller. At present, the vacuum pump control system on the market can obtain limited signals and interactive controllers, and its control logic is relatively simple. Only limited signals can be used to start, close and alarm the vacuum pump. Con...
