Abstract: A control apparatus according to the present disclosure is configured to perform a process of calculating a command torque that is given to a steering mechanism, an adjustment gain calculation process in which an adjustment gain for the command torque is calculated based on a steering torque, a process of calculating an adjusted command torque obtained by applying the adjustment gain to the command torque, and a process of controlling the steering mechanism in accordance with the adjusted command torque. It should be noted herein that the adjustment gain calculation process includes a process of calculating an adjusted steering torque having predetermined hysteresis characteristics with respect to changes in the steering torque, based on the steering torque, and a process of converting the adjusted steering torque into the adjustment gain.

Abstract: A steering control device that controls steering of a vehicle in which automatic driving or driving assistance is performed includes a reference steering angle calculation unit that calculates a reference steering angle of the vehicle based on a target steering angle and a vehicle speed of the vehicle, and a compensation unit that determines whether a deviation between the calculated reference steering angle and the target steering angle is equal to or greater than a predetermined value, and when determination is made that the deviation is equal to or greater than the predetermined value, compensates for the calculated reference steering angle such that the calculated reference steering angle follows the target steering angle.

Abstract: A steering system (100) includes: a variable transmission ratio mechanism (19); a limiting mechanism (20) and control means (30). The variable transmission ratio mechanism (19) varies a transmission ratio between a steering angle and a steered angle. The limiting mechanism (20) suppresses a variation in the transmission ratio of the variable transmission ratio mechanism (19). The control means (30) controls the variable transmission ratio mechanism (19). For example, the variable transmission ratio mechanism (19) uses a motor (40) to vary the transmission ratio, and the control means (30) controls a magnitude of current supplied to the motor to control the variable transmission ratio mechanism (19). The control means decreases a rate of contribution of I operation in feedback control over the variable transmission ratio mechanism (19) when the limiting mechanism (20) is operated as compared with a rate of contribution of I operation when the limiting mechanism (20) is not operated.

The applied friction torque changing unit changes the applied friction torque based on a load condition of the vehicle.

Abstract: A steering apparatus that by effecting a predetermined relationship between a steering wheel angle and a yaw angular velocity generated for a vehicle makes a direction ?gaze ?, seen from the view point of the driver, of a target destination point on a target course for vehicle travel after a predetermined forward gaze time, and a direction ?SW of a steering wheel reference position, seen from the view point of the driver, coincide with each other. The steering apparatus can accordingly enhance the sensation of driver-vehicle togetherness, thereby enabling steering to be performed that matches driver sensation and does not cause discomfort.

Abstract: A power steering device sets an applied friction torque applied to a steering wheel based on a real steering angle and a target steering angle, and performs a control of applying the applied friction torque to the steering wheel. An applied friction torque changing unit changes the applied friction torque, which is calculated from the real steering angle and the target steering angle, when the vehicle reverses. Concretely, the unit changes the applied friction torque to a smaller value when the vehicle reverses than that when the vehicle advances. Thereby, it is possible to decrease the applied friction torque properly when the vehicle reverses, and it become possible to improve the maneuverability of the steering wheel.
