Abstract:
1. A vehicle body drifting suppression device configured to perform a vehicle body drifting suppression control that suppresses a vehicle body drifting toward a lower portion of a road surface on which the vehicle body is traveling, the lower portion being lower with respect to a horizontal direction of the road surface due to an inclination of the road surface crosswise to a direction of travel of the vehicle body comprising: a steering torque detection unit which detects a steering torque of a vehicle; a yaw rate detection unit which detects a yaw rate of the vehicle, a steering angle detection unit which detects a steering angle, a vehicle body drifting assertion part which asserts that the vehicle is in a drifting status when: wherein when the steering torque is maintained at a value equal to or larger than a first predetermined value for longer than a first predetermined amount of time, the vehicle body drifting suppression control-amount is increased over the previous value, and when the previous value of the vehicle body drifting suppression control-amount is set equal to or greater than a predetermined amount larger than 0 and the steering torque is maintained at an absolute value equal to or smaller than a second predetermined value for longer than a second predetermined amount of time, the vehicle body drifting suppression control-amount is decreased smaller than the previous value, wherein the second predetermined value is smaller than the first predetermined value.
