STEERING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240246601 titled 'STEERING SYSTEM

Simplified Explanation:

This patent application describes a steer-by-wire steering system for a vehicle that includes a reaction force actuator, a steering actuator, and a controller. The system is capable of setting a neutral position and holding a motion position at that neutral position.

• The system includes a reaction force actuator that applies an operation reaction force to an operation member.
• A steering actuator is connected to a wheel and steers it using a power source.
• The controller is responsible for controlling both actuators and can set a neutral position and hold a motion position at that neutral position.

Key Features and Innovation:

• Integration of a reaction force actuator and a steering actuator in a steer-by-wire system.
• Ability to set a neutral position and hold a motion position at that neutral position.
• Controller capable of controlling both actuators for optimal steering performance.

Potential Applications:

This technology can be applied in autonomous vehicles, electric vehicles, and advanced driver assistance systems.

Problems Solved:

• Enhances steering precision and control.
• Improves overall vehicle handling and safety.
• Enables smoother and more efficient steering operations.

Benefits:

• Increased safety on the road.
• Enhanced driving experience.
• Potential for improved fuel efficiency in vehicles.

Commercial Applications:

Potential commercial applications include automotive industry suppliers, vehicle manufacturers, and companies developing autonomous driving technologies.

Questions about Steer-by-Wire Steering System:

1. How does the integration of a reaction force actuator and a steering actuator improve vehicle steering performance? 2. What are the potential safety benefits of implementing a steer-by-wire steering system in vehicles?

Original Abstract Submitted

a steer-by-wire steering system for a vehicle includes: a reaction force actuator to which an operation member is connected such that the reaction force actuator is moved by the operation member, the reaction force actuator including a power source by which the reaction force actuator applies an operation reaction force to the operation member; a steering actuator to which a wheel is connected, the steering actuator including a power source by which the steering actuator steers the wheel; and a controller configured to control the reaction force actuator and the steering actuator. the controller is configured to execute, for the reaction force actuator, the steering actuator, or both the reaction force actuator and the steering actuator, a neutral position setting processing of setting a neutral position in a motion range and a motion position hold processing of holding a motion position at the neutral position by the power source.
