CONTROL DEVICE FOR FOUR-WHEEL STEERING VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240278829 titled 'CONTROL DEVICE FOR FOUR-WHEEL STEERING VEHICLE

Simplified Explanation: The patent application describes a control device for a four-wheel steering vehicle that operates the front and rear wheel steering devices in response to steering inputs, with specific restrictions when the rear wheels are steered in the opposite direction to the front wheels.

The control device manages the steering of both front and rear wheels in a four-wheel steering vehicle.
It ensures that the steered angle velocity of the front wheels meets specific thresholds when the rear wheels are steered in the opposite direction.
Restrictions are placed on the steering of the rear wheels in certain conditions to optimize vehicle performance.

Potential Applications: This technology could be applied in advanced automotive systems, particularly in vehicles with four-wheel steering capabilities. It may enhance vehicle maneuverability and stability in various driving conditions.

Problems Solved: The technology addresses the challenge of coordinating front and rear wheel steering in a four-wheel steering vehicle to optimize performance and ensure safe operation.

Benefits: - Improved vehicle handling and maneuverability - Enhanced stability and control during steering maneuvers - Optimal coordination between front and rear wheel steering systems

Commercial Applications: The technology could be utilized in high-end automotive models, sports cars, and off-road vehicles to enhance driving dynamics and overall performance.

Prior Art: Prior art related to this technology may include patents or research on four-wheel steering systems, vehicle dynamics control, and steering coordination in automotive applications.

Frequently Updated Research: Researchers may be exploring advancements in four-wheel steering technology, vehicle control algorithms, and integration of steering systems for improved performance.

Questions about Four-Wheel Steering Technology: 1. How does the control device optimize steering coordination between front and rear wheels in a four-wheel steering vehicle? 2. What are the key factors influencing the restrictions placed on rear wheel steering in response to specific steering inputs?

Original Abstract Submitted

a control device for a four-wheel steering vehicle including a steering wheel, a front wheel steering device, and a rear wheel steering device, and operating the front wheel steering device and the rear wheel steering device, wherein first steering and second steering are continuously performed, and when the rear wheels are steered in the direction opposite to the steering direction of the front wheels, the absolute value of the steered angle velocity of the front wheels to be steered is higher than the first threshold, and the absolute value of the steered angle velocity of the front wheels to be steered in response to the second steering is higher than the second threshold, the steering of the rear wheels corresponding to the second steering is restricted.
