Steering control apparatus and a steering apparatus using the same

摘要

A steering control apparatus includes: a friction torque setting mechanism setting a friction torque value to be applied to a steering based on information representing a status of a vehicle; a target steering angle setting mechanism setting a target steering angle based on the set friction torque value; an adding friction torque setting mechanism setting an adding friction torque based on a deviation between the set target steering angle and a steering angle; and a steering friction torque controller controlling a friction torque applied to the steering by an actuator based on the set adding friction torque.

1. A steering control apparatus comprising:
a friction torque setting means for setting a friction torque value (Tt) based on information representing a status of a vehicle; a target steering angle setting means for setting a target steering angle (θt); an adding friction torque setting means for setting an adding friction torque (Tc) at least at a time when the target steering angle (θt) is not zero, based on a deviation between the set target steering angle (θt) and a steering angle (θ); and a steering friction torque controlling means for controlling a friction torque applied to a steering element by an actuator based on the set adding friction torque (Tc) wherein the target steering angle setting means is configured to set the target steering angle (Θt) based on the friction torque value (Tt); and wherein
the information representing the status of the vehicle includes information representing the steering angle (Θ), andin the friction torque setting means, the friction torque value (Tt) set when the steering angle (η) is a first steering angle is greater than the friction torque value (Tt) set when the steering angle (η) is a second vehicle steering angle, said second steering angle being smaller than the first steering angle.
