Abstract

A vehicle body drifting suppression device including a steering torque detection unit which detects a steering torque of a vehicle, wherein a vehicle body drifting suppression is performed according to a vehicle body drifting suppression control-amount, and the vehicle body drifting suppression control-amount is adjusted according to a temporal sustention status of the steering torque.

Claims

1. A vehicle body drifting suppression device comprising a steering torque detection unit which detects a steering torque of a vehicle, wherein

a vehicle body drifting suppression is performed according to a vehicle body drifting suppression control-amount, and

the vehicle body drifting suppression control-amount is adjusted according to a temporal sustention status of the steering torque.

2. The vehicle body drifting suppression device according to claim 1, wherein

when the steering torque is maintained at a value equal to or larger than a predetermined value for longer than a predetermined amount of time, the vehicle body drifting suppression control-amount is increased.

3. The vehicle body drifting suppression device according to claim 1, wherein

when the steering torque is maintained at a value equal to or smaller than a predetermined value for longer than a predetermined amount of time, the vehicle body drifting suppression control-amount is decreased.

4. The vehicle body drifting suppression device according to claim 1, wherein

the vehicle body drifting suppression includes a steering assisting control of an electronic power steering device,

the steering assisting control uses a target steering assisting torque as a base control amount, and

the vehicle body drifting suppression control-amount is calculated by adjusting the base control amount according to the steering torque.

5. The vehicle body drifting suppression device according to claim 1, wherein

the vehicle body drifting suppression includes a rear-steering angle control of a four-wheel steering device,

the steering assisting control uses a target rear-steering angle as a base control amount, and

the vehicle body drifting suppression control-amount is calculated by adjusting the base control amount according to the steering torque.

6. The vehicle body drifting suppression device according to claim 1, wherein

the vehicle body drifting suppression includes a driving torque control of a four-wheel driving device,

the steering assisting control uses a target left/right driving torque as a base control amount, and

the vehicle body drifting suppression control-amount is calculated by adjusting the base control amount according to the steering torque.

7. The vehicle body drifting suppression device according to claim 1, further comprising a vehicle body drifting assertion part, a yaw rate sensor, a steering angle sensor, and a steering torque sensor, wherein

the vehicle body drifting assertion part asserts whether a vehicle body is in a vehicle body drifting suppression steering status, based on output-signals from the yaw rate sensor, the steering angle sensor, and the steering torque sensor, and

the vehicle body drifting suppression is performed when the vehicle body is in the vehicle body drifting suppression steering status.
