If Steer-by-Wire system (SBW) is adopted in electric vehicles, which provide good solutions for environmental and energy crisis, both energy efficiency and automobile handling and stabilities will be higher. SBW adopts a road feel motor to feedback road feel to the driver hands and a steering motor to steer actively according to different driving status and driver's desire thus cuts off the traditional mechanical connection between steering wheel and steered wheels. Motor choice involving motor type and motor parameters match and motors layout in SBW are discussed. First motor control system hardware and software are presented. PID algorithm is adopted in lower control strategy. Finally hardware-in-loop bench test, which can simulate steering resistance that car meets when steering on actual road, is conducted to evaluate motor control validity of the two motors. Results show that presented motor motion control methods are valid.
