Vehicle safety method using steering angle feedback
The granted patent US12071172B2 outlines a method and system designed to enhance vehicle safety by monitoring and guiding the driver's steering behavior. The method involves determining the current steering angle of the vehicle and displaying it alongside a recommended steering angle. If the current steering angle deviates from the recommended angle, a visual warning is issued. The system continuously monitors the driver's adjustments to the steering angle, providing haptic feedback through the steering wheel until the current angle aligns with the recommended one. Additionally, the method includes the dynamic adjustment of the steering angle scale based on the vehicle's speed and the establishment of a safety envelope, which defines acceptable steering boundaries.
The patent further details the implementation of torque application to the steering wheel when the current angle is within a predetermined range of the recommended angle or the edges of the safety envelope. The system comprises various modules, including a steering angle detection module, a vehicle display for visual feedback, and a steering angle correction module that applies haptic feedback. This comprehensive approach aims to assist drivers in maintaining safe steering practices, thereby potentially reducing the risk of accidents related to steering misalignment.
