Driver-Vehicle Function Sharing for Safe Driving Skill Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems for autonomous driving fail to maintain or improve a driver's driving ability when their ability is insufficient, leading to reliance on the vehicle and inability to extend safe driving life.
Innovation Solution
A vehicle control apparatus that distributes driving functions between the driver and the vehicle, automatically compensating for low driving performance by performing necessary operations and providing training through assistance processing to maintain or improve driving ability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle substitutes for the driver's insufficient driving function, then safety of vehicle travel is ensured, but the driver's driving ability cannot be maintained or improved
Solution Approach 1:
The system provides feedback to the driver about their insufficient driving functions through notifications and suggestions. The ECU notifies the driver of the identified insufficient function and provides suggestions for improvement, enabling the driver to learn and improve their driving ability while maintaining safety through automated substitution when needed.
Solution Approach 2:
The system acts as an intermediary between the driver and the driving task. It identifies insufficient functions, substitutes for them when necessary to ensure safety, and simultaneously provides training feedback to help the driver improve. This intermediary role allows the system to balance safety requirements with driver development.
2Reliability
If the driver relies on the vehicle for insufficient driving ability, then safety is enhanced, but the driver cannot extend their safe driving life
Solution Approach 1:
The system provides continuous feedback to the driver about their driving performance and identifies specific insufficient functions. By notifying the driver and providing suggestions for improvement, the system enables progressive skill development that extends the driver's safe driving life while maintaining current safety levels through automated assistance.
Solution Approach 2:
The system performs preliminary identification of insufficient driving functions before they lead to safety incidents. By proactively detecting and notifying drivers of their weaknesses, the system allows for preventive training and improvement, extending the driver's safe driving capability over time.
3Reliability
If the vehicle performs all driving functions automatically, then safety is ensured, but the driver loses opportunity to maintain or improve driving skills
Solution Approach 1:
The system applies automated driving substitution selectively only for specific insufficient functions rather than all driving functions. This localized approach ensures safety for critical functions while leaving other functions to the driver, maintaining their skills and providing opportunities for improvement in non-critical areas.
Solution Approach 2:
The system performs partial automation - substituting only for the identified insufficient driving function rather than complete automation. This partial action is sufficient to ensure safety for the specific weakness while allowing the driver to maintain and improve other driving functions through continued practice.

AI summary
A vehicle control apparatus (100) executes: human-machine performance request setting processing to set a driving performance request in the given environments; driving performance determination processing to determine whether driving performance of each of plural driving functions of a driver satisfies the driving performance request; insufficient function identification processing to identify the driver's driving function that does not satisfy the driving performance request; driving function substitution processing to control the vehicle such that the vehicle performs the identified insufficient function instead; and driving performance assistance processing to provide the driver with an appropriate information so that the identified insufficient function close to a level of the driving performance request. The vehicle control apparatus (100) executes the driving function substitution processing and/or the driving performance assistance processing to make the driver and the vehicle (1) to exert the driving performance request.
