Abstract: In order to reduce exhaust emissions and environmental pollution,to solve excessive consumption of energy,using motor and engine to drive vehicle is a better choice at present. Electric driving system is a key component of HEV, deciding its- performance.Vector control and direct torque control strategy of Halbach permanent magnet synchronous motor based on HEV were studied.Results show that drive system based on vector control strategy can improve the performance of HEV better.
