Navigation System Route Selection Based on Driving Preference Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems in vehicles do not effectively allow drivers to select routes based on their preference for automated versus manual driving, which can lead to suboptimal route choices that do not align with their desired balance between comfort and control.
Innovation Solution
A navigation system with a human-machine interface and electronic controller that calculates multiple travel routes and allows users to select a route based on an automatic-manual driving preference ratio, determining which portions will be automated and which will require manual operation, enabling drivers to choose routes with varying levels of autonomous and manual driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the navigation system provides multiple route options with varying automated-manual driving ratios, then the driver's ability to select routes matching their preference is improved, but the system complexity increases due to additional calculation and selection criteria
Solution Approach 1:
The navigation system segments the route evaluation process into distinct components: calculating automated driving portions for each route segment, determining manual driving portions, computing the automatic-manual driving preference ratio, and finally selecting the optimal route. This segmentation allows the system to handle complex route selection by breaking it down into manageable computational steps, resolving the contradiction between providing versatile route options and maintaining system simplicity.
2Ease of operation
If the system calculates and presents multiple route options with different automated-manual driving ratios, then the driver's control and preference matching is improved, but the time required for route calculation and selection increases
Solution Approach 1:
The navigation system performs preliminary calculations of automated driving portions and manual driving portions for each potential route before the driver needs to make a selection. By pre-computing these values and the automatic-manual driving preference ratios, the system reduces the time required at the moment of route selection, allowing the driver to review multiple pre-analyzed options and make an informed decision without experiencing delays during the actual selection process.

AI summary
A navigation system is described for a vehicle equipped with an autonomous driving system. The navigation system includes a human-machine interface with a display and a user control, and an electronic controller. The controller is configured to calculate a plurality of travel routes from a determined starting point to a defined destination point. The controller determines which portions of each travel route will utilized automated driving operation and which portions will utilized manual driving operation. Based on an input received from the user control, the controller defines an automatic-manual driving preference ratio indicating a driver preference for an amount of manual driving operation relative to an amount of automatic driving operation. The controller automatically selects a route from the plurality of travel routes that most closely matches the defined automatic-manual driving preference ratio and outputs the selected route on the display.
