Vehicle Driving Assist Restart Logic for Driver Intent Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle driving assist systems lack the ability to discern and execute the specific driving assist controls desired by the driver upon restart, potentially continuing unwanted controls even after the driver has indicated a change in preference.
Innovation Solution
A vehicle driving assist apparatus equipped with an electronic control unit and a driving assist restart switch that allows the driver to explicitly stop or restart acceleration/deceleration and steering controls based on their intentions, using distinct operations to indicate rejection or stop of these controls, ensuring that only desired assist functions are reactivated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the driving assist control is restarted without considering driver intention, then the driving assist control can be quickly reactivated, but the driver may not receive the specific assist control they desire to execute
Solution Approach 1:
The restart function is segmented into two distinct operations: a first operation (e.g., brief press) that restarts acceleration/deceleration control, and a second operation (e.g., prolonged press) that restarts steering control. This segmentation allows the system to quickly reactivate the specific assist control the driver desires without requiring complex intention detection algorithms.
2Adaptability or versatility
If the system executes both acceleration/deceleration control and steering control simultaneously, then comprehensive driving assist is provided, but the system complexity increases
Solution Approach 1:
The system dynamically adjusts the restart behavior based on the current execution state of different assist controls. When both acceleration/deceleration control and steering control are executing, the restart operation selectively reactivates only the appropriate control, avoiding the need for complex simultaneous management while maintaining comprehensive assist capability.
3Ease of operation
If the driving assist restart switch operates without distinction between control types, then the operation is simple, but the system cannot determine which specific assist control the driver wants to restart
Solution Approach 1:
The system performs preliminary actions by detecting the specific operation pattern (first or second operation) before restarting the assist control. This preliminary detection of operation type allows the system to infer driver intent and restart the appropriate control, maintaining operational simplicity while preserving driver intent information.

AI summary
The vehicle driving assist apparatus can execute at least one of an acceleration/deceleration control as a driving assist control to automatically accelerate and decelerate an own vehicle and a steering control as the driving assist control to automatically steer the own vehicle. The vehicle driving assist apparatus includes a driving assist restart switch operated by a driver of the own vehicle to restart the driving assist control. The vehicle driving assist apparatus does not restart the acceleration/deceleration control even when the driving assist restart switch is operated after stopping the acceleration/deceleration control in response to the driver performing an automatic acceleration/deceleration rejection operation. The vehicle driving assist apparatus does not restart the steering control even when the driving assist restart switch is operated after stopping the steering control in response to the driver performing an automatic steering rejection operation.
