<p>PURPOSE:To ensure control stability relating to changing a car speed by providing a motor drive control means by which outputting a motor control current to an electric motor is started by satisfying a control start condition and stopped by satisfying a control end condition CONSTITUTION:When a vehicle is in running, in a rear wheel steering angle control start condition judging means (c), a car speed detection value from a car speed detecting means (b) is judged for whether or not the value is the first preset car speed or more, and in a motor drive control means (e), outputting a motor control current to an electric motor (a) is started by satisfying a control start condition for starting control of a rear wheel steering angle. In a rear wheel steering angle control end condition judging means (d), the car speed detection value from the car speed detecting means (b) is judged for whether or not the value is lower than the first preset car speed and a car speed just before stopping the vehicle is the second preset car speed or less.</p> |
