The invention relates to a control system and a control method based on a motor resolver sensor and a wheel speed sensor. An anti-lock braking control module of the control system is integrated in a motor controller, and a wheel speed sensor is used for collecting a wheel speed signal of an electric wheel and sending the wheel speed signal to a vehicle control unit; the vehicle control unit is used for carrying out driving anti-skid control according to the wheel speed signal; the motor resolver sensor is used for collecting a motor rotating speed signal and sending the motor rotating speed signal to the motor controller; and the motor controller is used for carrying out driving motor control according to the motor rotating speed signal and carrying out anti-lock braking control accordingto a target conversion wheel speed signal corresponding to the motor rotating speed signal, wherein the target conversion wheel speed signal comprises a signal obtained after the motor rotating speedsignal is input into a preset torsional vibration equation. By adopting the system, the control precision and the response speed of vehicle control can be improved.
