STEERING CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18543558 titled 'STEERING CONTROL DEVICE
Simplified Explanation:
This patent application describes a steering control device that can control the reaction force given to the steering wheel and the turning wheel in a situation where the dynamic force transmission between them is not performed.
- The processor controls the reaction force given to the steering wheel by adjusting the torque of the reaction force motor based on a command variable.
- It reflects a predetermined component of a frequency signal given to the turning wheel in the value of the reaction force command variable.
- It restricts the contribution of the predetermined component to the reaction force command variable to a smaller degree in unstable steering system situations.
Key Features and Innovation:
- Control of reaction force between steering wheel and turning wheel without dynamic force transmission.
- Adjustment of reaction force torque based on command variable.
- Reflection of frequency signal component in reaction force command variable.
- Restriction of contribution of frequency signal component in unstable steering system situations.
Potential Applications:
This technology can be applied in various steering control systems for vehicles, especially in situations where stability is crucial.
Problems Solved:
- Control of reaction force in steering systems without dynamic force transmission.

Original Abstract Submitted
A steering control device includes a processor. The processor is configured to execute a process in a state where dynamic force transmission between a steering wheel and a turning wheel is not performed. The process includes: a process of controlling a reaction force that is given to the steering wheel, by operating torque of the reaction force motor depending on the value of a reaction force command variable; a process of reflecting a predetermined component of a frequency signal that is given to the turning wheel in the value of the reaction force command variable; and a process of restricting the degree of contribution of the predetermined component to the value of the reaction force command variable, to a smaller degree, in a situation where a steering system including the steering wheel is unstable.
