Steering Wheel Angular Orientation for Evasive Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current advanced driver assist systems often fail to provide sufficient steering guidance to drivers in imminent collision situations, leading to panic braking instead of evasive maneuvers, which can increase the risk of accidents.
Innovation Solution
A method and system that detect a target vehicle and provide a steering guidance by altering the steering wheel angular orientation to indicate an evasive steering action towards road markers, ensuring the driver is aware of the necessary direction to avoid a collision, while ensuring vehicle stability and safety conditions are met.

Engineering Contradiction Analysis
1Reliability
If a haptic signal in the steering wheel is used to indicate suggested steering direction, then the system causes no or insignificant change in driving direction, but the driver may not receive sufficient directional indication in high-stress situations
Solution Approach 1:
The system dynamically adjusts the steering wheel angular orientation based on the detected collision risk and target position. The steering wheel is altered to a specific angular orientation that points toward the free space, providing dynamic directional guidance that adapts to the changing situation rather than using a fixed haptic signal approach
Solution Approach 2:
The system changes the angular orientation parameter of the steering wheel to provide directional indication. By altering the steering wheel angle to point toward the safe direction, the system transforms a static steering component into an active communication device that conveys escape route information to the driver
2Ease of operation
If the driver is allowed to manually steer to avoid collision, then the driver has full control, but the driver may experience panic and brake instead of steering away
Solution Approach 1:
The altered steering wheel angular orientation serves as an intermediary between the collision detection system and the driver. It translates complex collision risk information into an intuitive directional indication that guides the driver's steering action toward the free space, bridging the gap between system detection and driver response
Solution Approach 2:
The system performs preliminary action by altering the steering wheel orientation before the driver needs to respond. The steering wheel is pre-positioned to indicate the correct steering direction, preparing the driver's motor response in advance and reducing reaction time during the critical escape maneuver

AI summary
A method for assisting a driver of a host vehicle in avoiding a collision, the method including: detecting a target in the vicinity of the vehicle; determining that the host vehicle is travelling on a collision course with the target; detecting a set of road markers on a side of the target; detecting a free space on the side of the road markers opposite the target side of the road markers, and when a collision with the target is predicted to occur within a predetermined time period and no driver initiated steering action for avoiding the collision course has been detected, providing a steering guidance to the driver of the host vehicle including altering of a steering wheel angular orientation for momentarily steering the host vehicle towards the road markers to indicate an evasive steering action to the driver.
