An ECU executes steering control in a vehicle including an electronic control power steering apparatus. In the steering control, it is determined that an assist motor is in a power generating state when a motor rotation speed ω which is the rotation speed of the assist motor is greater than an upper limit rotation speed ω1 set according to a motor command voltage Vq that is the driving voltage of the assist motor. When the assist motor is in the power generating state, the ECU interrupts the supply of current to the assist motor by controlling a relay portion of a drive apparatus that drives the assist motor so that it is open, thereby reducing the amount of power that is generated to zero. Also, when returning to an assist possible state, assist torque Tm is changed gradually with zero as the initial value in order to prevent it from changing suddenly.

The invention discloses a method and a system for controlling the operation of a car sunroof. The method comprises the following steps of: dividing the operating parameter of the movement of the sunroof into at least two sections according to a preset rule, and obtaining a target voltage value corresponding to each section and expected to be outputted to a motor; obtaining the power voltage value of a current section, calculating the duty ratio corresponding to the current section according to the power voltage value of the current section and the target voltage value of the current section, wherein the target voltage value of the current section is expected to be outputted to the motor; and controlling the soft starting and the soft stopping of the motor according to the duty ratio of the current section. According to the invention, the voltage inputted to the motor is slowly increased or reduced, so that the operation of the sunroof is controlled, and the condition that because of the noise and vibration brought by the sudden starting and stopping of the motor, the comfort reduction of a customer is reduced when the customer takes a car is reduced. Otherwise, during the process of the soft stopping, the target voltage in stopping is reduced because of the multi-time soft stopping method, so that the inertial forward-rushing distance when the motor commands the stopping under various working conditions is effectively controlled, and the position control precision of the stopping of the sunroof is improved.
