Controls and Steering

By independently controlling the steering angle of the vehicle steering wheel and correcting the steering command value with the electronic control unit, it is possible to reduce the side deviation resistance while maintaining the speed and turning radius when the vehicle passes through the curve, and improve fuel efficiency and driving stability.

AI Technical Summary

Technical Problem

The prior art is difficult to maintain the turning radius and speed simultaneously when a vehicle passes through a curve, resulting in poor fuel efficiency and driving stability.

Method used

By independently controlling the steering angles of the right steering wheel and the left steering wheel, the electronic control unit is used to correct the steering command value based on the steering direction, target path and slip angle information of the vehicle, so that the slip angle allocation ratio of the right steering wheel and the left steering wheel reaches the target allocation ratio.

Benefits of technology

While maintaining the speed and turning radius of the vehicle through the curve, the side deviation resistance is reduced, thereby improving fuel efficiency and enhancing driving stability.

Abstract

The invention relates to a control device and a steering device. The control device (140) includes an electronic control unit. The electronic control unit determines a right steering command value and a left steering command value. The electronic control unit obtains path information indicating a target path of a vehicle (101). The electronic control unit corrects the steering command value so that the vehicle (101) travels along the target path. The electronic control unit corrects the right steering command value and the left steering command value so that the distribution ratio between the slip angle of the right steering wheel (120) and the slip angle of the left steering wheel (110) becomes a target distribution ratio.
