Navigation Display System for Driver Burden Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems do not effectively account for driver and road burden conditions, leading to potential stress and safety issues during vehicle navigation.
Innovation Solution
A vehicle navigation system equipped with a user input interface, electronic display device, and processor that acquires burden conditions from the user, real-time information from a satellite navigation device, and crowdsourced data to display optimized route selections based on driver and road conditions.

Engineering Contradiction Analysis
1Measurement precision
If traditional navigation systems provide detailed route information and multiple route options, then navigation accuracy and route selection capability are improved, but driver cognitive burden and stress increase
Solution Approach 1:
The system applies different information presentation strategies based on the specific road segment and driver state. Complex route information is provided only when necessary, while simpler presentations are used on straightforward sections, optimizing the balance between navigation accuracy and driver burden.
Solution Approach 2:
The navigation system dynamically adjusts the amount and type of information displayed based on real-time driver state monitoring. When driver fatigue or stress is detected, the system reduces information complexity and provides more guidance, thereby maintaining navigation accuracy while adapting to driver capabilities.
2Adaptability or versatility
If the navigation system provides comprehensive real-time information and multiple route options, then route selection quality is improved, but information processing time and driver attention requirements increase
Solution Approach 1:
The system pre-calculates multiple route options and prepares information about upcoming maneuvers before the driver needs to make decisions. This allows the driver to receive processed, ready-to-act information rather than raw data requiring additional processing time.
Solution Approach 2:
The system monitors driver response times and attention levels, using this feedback to adjust the pace and detail of information presentation. When the driver appears overwhelmed, the system slows down information delivery and provides more lead time for processing.
3Ease of operation
If the navigation system monitors driver state continuously to personalize route recommendations, then driver burden reduction is improved, but system complexity and data processing requirements increase
Solution Approach 1:
The system uses a multi-functional monitoring apparatus that simultaneously tracks multiple driver parameters (eye movement, steering patterns, response time) using a single integrated device rather than separate sensors for each parameter, reducing overall system complexity.
Solution Approach 2:
The driver contributes to the monitoring process by providing explicit feedback through the interface (e.g., indicating when they feel overwhelmed), which complements automatic sensing and reduces the need for complex interpretation algorithms.

AI summary
A vehicle includes a user input interface, an electronic display device and a processor. The user input interface is configured to allow a user to input one or more burden conditions of the user. The electronic display device is positioned in an interior compartment of the vehicle. The processor is programmed to control the electronic display device to display one or more route selections, the one or more route selections being based on the burden conditions.
