一种无大气压力传感器时的电动真空泵控制系统
摘要：
本发明公开了一种无大气压力传感器时的电动真空泵控制系统，所述电动真空泵根据大气压力值确定工作区间，还包括大气压力即时修正单元；所述大气压力即时修正单元根据车辆当前所在的经度信息、和/或纬度信息、和/或海拔高度信息、和/或当前时间信息而获得大气压力修正系数；所述电动真空泵根据标准大气压力值和大气压力修正系数而确定工作区间。本发明所述的无大气压力传感器时的电动真空泵控制系统中，通过获取电动汽车所处地点的经度、纬度、海拔、时间等信息，进而确定大气压力修正系数，所述电动真空泵参考该大气修正系数而调整工作区间，可以在确保整车的制动性能正常，还能避免电动真空泵过工作而引起的耗电增加。
摘要（英）：

The invention discloses an electric vacuum pump control system without a barometric pressure sensor. An electric vacuum pump determines a workspace according to barometric pressure values, the systemcomprises a barometric pressure real-time correction unit for acquiring barometric pressure correction coefficient according to current longitude information, and/or latitude information, and/or altitude information and/or current time information of a vehicle, and the electric vacuum pump determines the workspace according to standard barometric pressure values and the barometric pressure correction coefficient. According to the electric vacuum pump control system without the barometric pressure sensor, the information such as longitude, latitude, altitude and time of a place with an electricvehicle is acquired to determine the barometric pressure correction coefficient, the electric vacuum pump adjusts the workspace by referring to the barometric pressure correction coefficient, normalbrake performance of the whole vehicle can be ensured, and power consumption increase caused by over-work of the electric vacuum pump can be avoided.
