Driver Assistance System Route Recalculation Based on Driver Eagerness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving vehicles often deviate from planned routes due to traffic congestion, construction, or other environmental factors, leading to inefficient route recalculations and prolonged travel times, especially when drivers are in a hurry.
Innovation Solution
A driver-assisting system that includes an autonomous drive apparatus, navigation apparatus, detector, eagerness determiner, and controller to switch between autonomous and manual drive modes based on the driver's eagerness to arrive at the destination, suggesting alternative or fastest routes and mode changes accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the navigation apparatus recalculates a new route when the vehicle deviates from the original route during autonomous drive mode, then the vehicle can reach the destination through an alternative route, but the recalculated route may be inappropriate for the driver in certain conditions such as too close, congested traffic, construction work, and the vehicle may miss it again
Solution Approach 1:
The system determines driver eagerness in advance before route recalculation occurs. By assessing the driver's state beforehand, the system can prepare appropriate route suggestions that match the driver's current condition, preventing inappropriate recalculation decisions and reducing the need for multiple recalculations
Solution Approach 2:
The system continuously monitors driver eagerness level and uses this feedback to dynamically adjust route recalculation behavior. When driver eagerness is high, the system prioritizes faster routes; when low, it considers alternative routes, creating a closed-loop control system that adapts to driver state changes
2Productivity
If the navigation apparatus generates an alternative route when the vehicle deviates from the original route, then the vehicle can continue autonomous drive mode, but the alternative route may be inappropriate for the driver who is in a hurry, consuming much more time
Solution Approach 1:
The system dynamically adjusts route selection based on the driver's eagerness level. When driver eagerness is high, the system selects faster routes even if they require manual drive mode; when driver eagerness is low, it selects alternative routes suitable for autonomous drive mode. This dynamic adaptation resolves the contradiction between travel efficiency and route selection flexibility
Solution Approach 2:
The system changes the route selection parameters based on driver eagerness. By adjusting which parameters are prioritized (arrival time vs. route suitability) according to driver state, the system can optimize travel efficiency for different driver conditions without sacrificing adaptability
3Reliability
If the vehicle keeps missing exits on a freeway during autonomous drive mode, then the navigation apparatus continuously recalculates routes, but much more time is consumed compared to when the driver drives the vehicle
Solution Approach 1:
The system determines driver eagerness in advance to prevent continuous inappropriate route recalculations. By knowing the driver's state beforehand, the system can make more accurate exit detection decisions and avoid unnecessary recalculations that would consume time
Solution Approach 2:
The system uses driver eagerness feedback to control route recalculation frequency and timing. When driver eagerness is high, the system minimizes recalculation interruptions; when low, it allows more flexible recalculation. This feedback mechanism prevents time-consuming continuous recalculations while maintaining reliable exit detection

AI summary
A driver assisting system for a vehicle that is capable of operating in an autonomous drive mode and a manual drive mode is provided. The driver assisting system includes: an autonomous drive apparatus that controls the vehicle during the autonomous drive mode; a navigation apparatus; a detector that obtains information associated with an eagerness of the driver; an eagerness determiner that determines; and a controller that switches between the autonomous drive mode and the manual drive mode. The navigation apparatus is configured to initially suggest an original route, suggest an alternative route, and suggest a fastest route when the vehicle deviates from the original route and the eagerness determiner determines that the driver is in the high eagerness state. The controller is configured to set the autonomous drive mode, maintain the autonomous drive mode, and switch to the manual drive mode.
