Abstract
A vehicle turn control apparatus includes an electronic control unit, which computes a required control valve for yaw moment control in accordance with the operating condition and/or behavior of a vehicle, actuates a pump when a first predetermined value is reached by the required control valve, and starts operation control for hydraulic pressure control valves when a request for turn control is made after a second predetermined value is reached by the required control valve. Since the pump is already actuated at the start of the control, the turn control can be quickly started without a delay in response to the turn control request. A hydraulic pressure, generated by the pump and adjusted by the hydraulic pressure control valves, is supplied to wheel brakes during the turn control. Thereupon, braking force differences are caused between the wheels of the vehicle, whereby the yaw moment of the vehicle is controlled.
