Problems solved by technology

[0004] However, as described in Patent Document 1, regardless of the vehicle speed, if the toe angles of the left and right rear wheels are controlled based on the steering angle (of the steering wheel), the responsiveness of the vehicle when turning is reduced.
[0005] For example, when snaking driving is considered, there will be a lag in the responsiveness of the turning in the control according to the steering angle. If you do not want the responsiveness to lag, it may damage the stability.

Abstract

The present invention improves response characteristics in turning traveling of a vehicle while traveling stability at the time of turning is kept. The present invention provides a system in which toe angles of left and right rear wheels are controlled based on a steering angular velocity, not a steering angle of a steering. In a steering system 100 in which toe angles of left and right rear wheels are controlled independently, a steering angular velocity omega H is calculated from a steering angle theta H , and toe angle changers 120L, 120R are controlled to tilt the toe angle of the right rear wheel to the left when the steering angular velocity omega H is on the left side, and is controlled to tilt the toe angle of the left rear wheel to the left when the steering angular velocity omega H is on the right side.

Description

technical field [0001] The present invention relates to, for example, a steering system for a vehicle that independently controls the toe angles of the left and right rear wheels of a four-wheeled vehicle. Background technique [0002] Conventionally, various proposals have been made for a four-wheel steering system that controls the toe angle of the rear wheels for the purpose of improving the turning performance of the vehicle. For example, Patent Document 1 discloses a technology for independently controlling the toe angles of the left and right rear wheels based on the steering angle of the steering wheel (steering wheel) and the running speed (vehicle speed) of the vehicle. [0003] Patent Document 1: Japanese Patent Application Publication No. 6-47388 (Claim 1, etc.) [0004] However, as described in Patent Document 1, regardless of the vehicle speed, if the toe angles of the left and right rear wheels are controlled based on the steering angle (of the steering wheel)...
