Emergency Steering Handoff Alerts to Prevent Driver Wheel Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to prevent drivers from interfering with autonomous emergency avoidance steering when the driver touches the steering wheel during execution.
Innovation Solution
A vehicle control system that outputs a first notification command to urge the driver to avoid touching the steering wheel before transitioning to autonomous emergency avoidance steering mode, using a combination of visual, auditory, and vibratory notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system executes autonomous emergency avoidance steering when the driver touches the steering wheel, then the emergency avoidance maneuver can be performed, but the driver's contact with the steering wheel interferes with and hinders the execution of the autonomous emergency avoidance steering
Solution Approach 1:
The notification unit provides advance notification to the driver before autonomous emergency avoidance steering is executed, urging the driver to release the steering wheel. This preliminary action prevents the driver's contact from interfering with the upcoming autonomous maneuver, thereby ensuring reliable execution while maintaining the driver's natural ability to operate the vehicle.
Solution Approach 2:
The system performs preliminary notification and preparation before executing the autonomous emergency avoidance steering. By notifying the driver in advance and providing a brief preparation period, the system ensures that the driver releases the steering wheel before the autonomous maneuver begins, preventing interference while maintaining operational ease.
2Loss of information
If the system notifies the driver in advance of autonomous emergency avoidance steering execution, then the driver is aware of the upcoming maneuver, but the autonomous emergency avoidance steering may still be hindered if the driver touches the steering wheel during execution
Solution Approach 1:
The notification unit not only informs the driver of the upcoming autonomous emergency avoidance steering but also specifically urges the driver to release the steering wheel. This dual-purpose notification prevents both information loss and execution interference by addressing the steering wheel contact issue proactively before the maneuver begins.
Solution Approach 2:
The notification system provides feedback to the driver about the system's intent to execute autonomous emergency avoidance steering and the desired driver response (releasing the steering wheel). This feedback loop ensures the driver understands both what will happen and what action they should take, maintaining both awareness and execution reliability.
3Adaptability or versatility
If the system allows the driver to touch the steering wheel during autonomous emergency avoidance steering, then the driver maintains control capability, but the autonomous emergency avoidance steering execution is hindered and cannot be performed smoothly
Solution Approach 1:
By notifying the driver in advance to release the steering wheel, the system prevents the driver's contact from hindering the autonomous maneuver. This preliminary action maintains the driver's control capability (adaptability) while ensuring smooth, uninterrupted execution (productivity) of the emergency avoidance steering.
Solution Approach 2:
The system dynamically adjusts the driver-vehicle interaction by temporarily modifying the steering wheel's responsiveness or providing haptic feedback to guide the driver to release it. This dynamic adjustment maintains driver control capability while ensuring efficient autonomous execution during the critical emergency avoidance maneuver.

AI summary
A vehicle control controller is configured to acquire information on an obstacle in front of a vehicle acquired by an external world recognition device, and to output, based on the acquired obstacle position and own vehicle position, a first notification command for controlling a notification unit so as to give to a driver a notification for urging the driver to avoid touching a steering wheel when transitioning to an autonomous emergency avoidance steering mode for avoiding the obstacle based on control by an electric power steering device.
