Document Type and Number:
Japanese Patent JP2020082915
Kind Code:
A
Abstract:
To provide a steering device that can perform lane keep control and automatic parking control and that can prevent vibration from being generated during the automatic parking control.SOLUTION: A steering device includes a control unit 40 configured to change a steering angle by controlling an electric motor 18 that can steer and turn driving wheels. The control unit 40 includes: an angle feedback control part 44 capable of executing lane keep control to perform feed back control such that an actual steering angle coincides with a first target steering angle calculated so that a vehicle travels along a target route set in a traveling course, and an automatic parking control to perform feedback control such that an actual steering angle coincides with a second target steering angle calculated so that the vehicle moves from a current position to a parking position; and a gain setting part 51 configured to set a feedback gain in the automatic parking control to be a value smaller than a feedback gain in the lane keep control.SELECTED DRAWING: Figure 2
