Control device for applying torque to a steering member
Assist torque or reaction force torque with little unnatural feeling to a driver is applied. An ECU includes: a control amount calculation section that calculates a control amount for controlling magnitude of the assist torque or the reaction force torque with reference to steering torque applied to a steering member; and a control amount correction section that corrects the control amount calculated by the control amount calculation section with reference to a lateral G of a vehicle body, a steering angle of the steering member, and a steering angle speed of the steering member.
1. A control device comprising:
a control amount calculation section configured to calculate a control amount for controlling a magnitude of a reaction force torque with reference to a steering torque applied to a steering member; and
a control amount correction section configured to correct the control amount calculated by the control amount calculation section with reference to acceleration in a lateral direction of a vehicle body, a steering angle of the steering member, and a steering angle speed of the steering member, wherein
the control device is configured to apply the reaction force torque to the steering member, and
the control amount correction section is configured to correct the control amount calculated by the control amount calculation section such that the reaction force torque applied to the steering member becomes larger when the steering member is in a switch-back state, the steering angle speed of the steering member or an absolute value thereof is equal to or greater than a predetermined value, and the acceleration in the lateral direction of the vehicle body or an absolute value thereof is less than a predetermined value.
2. A control device comprising:
a control amount calculation section configured to calculate a control amount for controlling a magnitude of a reaction force torque with reference to a steering torque applied to a steering member; and
a control amount correction section configured to correct the control amount calculated by the control amount calculation section with reference to a yaw rate of a vehicle body, a steering angle of the steering member, and a steering angle speed of the steering member, wherein
the control device is configured to apply the reaction force torque to the steering member, and
the control amount correction section is configured to correct the control amount calculated by the control amount calculation section such that the reaction force torque applied to the steering member becomes larger when the steering member is in a switch-back state, the steering angle speed of the steering member or an absolute value thereof is equal to or greater than a predetermined value, and acceleration in a lateral direction of the vehicle body calculated by using the yaw rate or an absolute value thereof is less than a predetermined value.
