STEERING DEVICE AND METHOD FOR CONTROLLING STEERING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18261061 titled 'STEERING DEVICE AND METHOD FOR CONTROLLING STEERING DEVICE

Simplified Explanation

The steering device and method described in the abstract aim to control a steer-by-wire steering device by adjusting the turning angle command value to prevent the yaw rate gain of the vehicle from becoming too sensitive during steering operations.

• The innovation involves a steer-by-wire steering device with a steering operation input member and a turning actuator that adjusts the turning force applied to a road wheel based on a driving signal.
• When the turning frequency of the road wheel reaches a predetermined frequency, the turning angle command value is reduced to an angle less than the original angle to prevent the vehicle's yaw rate gain from increasing too much in response to the steering operation speed.

Potential Applications

The technology can be applied in the automotive industry for vehicles equipped with steer-by-wire systems to enhance steering control and stability.

Problems Solved

1. Preventing the yaw rate gain of the vehicle from becoming overly sensitive during steering operations. 2. Enhancing the overall safety and stability of the vehicle during steering maneuvers.

Benefits

1. Improved control and stability during steering operations. 2. Enhanced safety for drivers and passengers. 3. Optimal performance of the steer-by-wire steering system.

Potential Commercial Applications

Enhancing the steering control and safety features of vehicles equipped with steer-by-wire systems for various automotive manufacturers.

Original Abstract Submitted

A steering device and a method for controlling the steering device according to the present invention are capable of suppressing, in a steer-by-wire steering device including a steering operation input member and a turning actuator that applies a turning force to a road wheel based on a driving signal, a change in which a yaw rate gain of a vehicle rises with respect to the operation speed of the steering operation input member by changing a turning angle command value to an angle less than the angle before the change when a turning frequency of the road wheel is a predetermined frequency. As a result, it becomes possible to suppress a case in which the yaw rate gain of the vehicle becomes too sensitive with respect to a steering operation by a driver.
