Redundant Control System and Method for Autonomous Steering - A simplified explanation of the abstract
This abstract first appeared for US patent application 18045996 titled 'Redundant Control System and Method for Autonomous Steering
Simplified Explanation
The abstract describes a redundant control system for autonomous steering in vehicles. The system includes a sensor for autonomous driving, a main steerer with a steering motor, a first autonomous controller for real-time lane recognition and controlling the main steerer, an auxiliary steerer with a brake module, and a second autonomous controller for supplementary steering and backup braking.
- The system includes a sensor that gathers information for autonomous driving.
- A main steerer is responsible for steering the vehicle and is controlled by a first autonomous controller.
- The first autonomous controller uses data from the sensor to determine the target steering angle through real-time lane recognition.
- An auxiliary steerer is equipped with a brake module, consisting of a main brake and an auxiliary brake, for performing steering.
- A second autonomous controller controls the auxiliary steerer to provide supplementary steering through partial braking and additional actuation in case of abnormal operation of the automatic steering function.
- The second autonomous controller also controls backup braking through the auxiliary brake when the main brake fails.
Potential Applications
- Autonomous vehicles: The system can be applied to autonomous vehicles to enhance their steering capabilities and provide redundancy in case of failures.
- Automotive safety: The redundant control system can improve the safety of autonomous vehicles by ensuring reliable steering and backup braking.
Problems Solved
- Redundancy: The system solves the problem of relying solely on a single steering mechanism by providing an auxiliary steerer with backup braking capabilities.
- Abnormal operation: The second autonomous controller addresses the issue of abnormal operation of the automatic steering function by providing supplementary steering through partial braking and additional actuation.
Benefits
- Enhanced safety: The redundant control system improves the safety of autonomous vehicles by providing backup steering and braking capabilities.
- Reliability: The system ensures reliable steering even in the event of failures or abnormal operation of the main steering mechanism.
- Real-time lane recognition: The first autonomous controller utilizes real-time lane recognition to determine the target steering angle, improving the accuracy of autonomous steering.
Original Abstract Submitted
An embodiment is a redundant control system for autonomous steering including a sensor in a vehicle configured to sense information for autonomous driving, a main steerer configured to actuate a steering motor to perform steering, first autonomous controller configured to use data provided from the sensor to determine a target steering angle through real-time lane recognition and to control the main steerer, an auxiliary steerer configured to use a brake module composed of a main brake and an auxiliary brake to perform steering, and a second autonomous controller configured to control the auxiliary steerer to perform supplementary steering through partial braking and application of additional actuation in the event of abnormal operation of an automatic steering function using the first autonomous controller and to control backup braking through the auxiliary brake when the main brake fails.
