Vehicle oil pump motor control system

Abstract

The invention relates to the technical field of vehicle oil pump motors, and discloses a vehicle oil pump motor control system. The system involves a direct current power battery which is independentof a vehicle power battery platform, a full bridge inverter circuit, a current sampling sensor, an oil pump motor, a rotation speed detection sensor and a controller, wherein the direct current powerbattery is electrically connected with the oil pump motor through the full bridge inverter circuit, the current sampling sensor is arranged on the part, between the full bridge inverter circuit and the oil pump motor, of a wire, the rotation speed detection sensor is arranged on the oil pump motor, the current sampling sensor and the rotation speed detection sensor are electrically connected withthe controller, and the controller is electrically connected with the full bridge inverter circuit. The vehicle oil pump motor control system is independent of the vehicle power battery platform, andcan still control a vehicle steering wheel when the vehicle power battery platform fails, so it is guaranteed that a vehicle does not lose control.
