STEERING SYSTEM AND CONTROL METHOD FOR STEERING SYSTEM
First Claim
1. A steering system comprisingan electronic control unit configured to:
- set a ratio of a turning angle change amount with respect to a steering angle change amount in a first steering angle area to be larger than the ratio of the turning angle change amount with respect to the steering angle change amount in a second steering angle area, a steering angle of the second steering angle area being smaller than the steering angle of the first steering angle area; and
perform a first process of setting a delay degree of a change in turning angle with respect to a change in steering angle in the first steering angle area to be larger than the delay degree of the change in turning angle with respect to the change in steering angle in the second steering angle area regardless of a turning-over operation or a turning-back operation.

Abstract
A steering system is configured such that a ratio of a turning angle change amount with respect to a steering angle change amount in a first steering angle area is larger than the ratio of the turning angle change amount with respect to the steering angle change amount in a second steering angle area, and a steering angle in the second steering angle is smaller than the steering angle of the first steering angle area. An electronic control unit of the steering system sets a delay degree of a change in turning angle with respect to a change in steering angle in the first steering angle area to be larger than the delay degree of the change in turning angle with respect to the change in steering angle in the second steering angle area regardless of a turning-over operation or a turning-back operation.

11. A control method for a steering system comprising:
-
setting a ratio of a turning angle change amount with respect to a steering angle change amount in a first steering angle area to be larger than the ratio of the turning angle change amount with respect to the steering angle change amount in a second steering angle area by an electronic control unit, a steering angle in the second steering angle area being smaller than the steering angle in the first steering angle area; and setting a delay degree of a change in turning angle with respect to a change in steering angle in the first steering angle area to be larger than a delay degree of a change in turning angle with respect to a change in steering angle in the second steering angle area by the electronic control unit regardless of a turning-over operation or a turning-back operation.
