Autonomous Driving Mode Switching Based on Driver Interest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving systems fail to balance consideration for the driver's preference with the potential performance of the vehicle, often prioritizing one over the other, leading to suboptimal vehicle performance.
Innovation Solution
An autonomous driving system that switches between a driver-oriented mode and a performance-oriented mode based on the driver's interest level, with the driver-oriented mode prioritizing driver settings and ride quality and the performance-oriented mode focusing on safety margin, time to destination, fuel economy, motion performance, and reduced driver notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If autonomous driving control prioritizes driver's preference and ride quality, then driver comfort and acceptance are improved, but vehicle's potential performance is not fully exercised
Solution Approach 1:
The system dynamically switches between driver-oriented mode and performance-oriented mode based on the driver's interest level. When the driver shows high interest in autonomous driving, the system operates in performance-oriented mode to maximize vehicle capabilities. When interest is low, it switches to driver-oriented mode to prioritize comfort and acceptance, thus resolving the contradiction between driver comfort and vehicle performance.
Solution Approach 2:
The system changes operational parameters based on driver interest level. In performance-oriented mode, parameters such as safety margins, notification frequencies, and driving behavior are adjusted to maximize vehicle performance. In driver-oriented mode, parameters are adjusted to prioritize driver comfort and preference, effectively resolving the contradiction through parameter adaptation.
2Reliability
If autonomous driving control prioritizes safety margin, then driving safety is improved, but ride quality and driver preference consideration deteriorate
Solution Approach 1:
The system dynamically adjusts safety margin levels based on driver interest and operational mode. In performance-oriented mode with high driver interest, larger safety margins are maintained to ensure safety while maximizing performance. In driver-oriented mode with low interest, safety margins are adjusted to balance safety with ride quality, resolving the contradiction between safety and comfort.
3Productivity
If autonomous driving control reduces notification frequency to driver, then system efficiency is improved, but driver awareness and control deteriorate
Solution Approach 1:
The system dynamically adjusts notification frequency based on driver interest level and operational mode. In performance-oriented mode with high driver interest, notification frequency is reduced to improve system efficiency and reduce distractions. In driver-oriented mode with low interest, notification frequency is increased to maintain driver awareness and control, effectively resolving the contradiction between efficiency and awareness.

AI summary
An autonomous driving system controls autonomous driving of a vehicle and calculates an interest level of a driver of the vehicle for the autonomous driving. In a driver-oriented mode, the autonomous driving system gives priority to at least one of setting by the driver, will of the driver, and ride quality. In a performance-oriented mode, the autonomous driving system gives priority to at least one of increase in a safety margin, reduction in a time to arrive at a destination, improvement in fuel economy, improvement in motion performance, and reduction in a frequency of notification to the driver. The autonomous driving system controls the autonomous driving in the driver-oriented mode in a case of a normal state, and controls the autonomous driving in the performance-oriented mode in a case of a low interest state where the interest level is lower than the normal state.
