Navigation System Power Consumption Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicles require a separate display device to optimize fuel consumption, which can distract the driver and is not integrated with navigation systems, making it difficult to achieve the lowest possible power consumption during travel routes suggested by navigation systems.
Innovation Solution
Displaying current power consumption on the navigation system's map image, allowing drivers to adjust their driving mode by showing fuel or electrical power consumption via numeric representation or color-coding the route based on consumption levels, eliminating the need for an additional display device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a separate display device is provided to show power consumption, then power consumption information can be displayed, but device complexity increases and driver distraction risk increases
Solution Approach 1:
The patent combines the power consumption display function with the existing navigation system display. The control unit integrates power consumption data from the drive motor with the map image displayed on the navigation system, eliminating the need for a separate display device. This merging approach maintains information completeness while reducing device complexity.
Solution Approach 2:
The navigation system display is made multi-functional by enabling it to show both navigation information (map image) and power consumption information simultaneously. This allows the existing display device to serve multiple purposes, reducing the need for additional specialized displays and controlling overall device complexity.
2Loss of information
If a separate display device is provided to show power consumption, then power consumption information can be displayed, but driver distraction increases
Solution Approach 1:
By merging the power consumption display with the navigation system that the driver already monitors for routing information, the patent ensures that power consumption data is viewed in the driver's existing visual attention zone. This integration allows drivers to obtain power consumption information without shifting attention to a separate device, reducing distraction.
3Ease of operation
If power consumption is displayed on the navigation system, then driver distraction is reduced, but the navigation system hardware and software complexity increases
Solution Approach 1:
The navigation system is enhanced with multi-functionality by adding power consumption display capability to its existing map image display function. The control unit processes and overlays power consumption data on the navigation display, allowing the system to serve multiple purposes without requiring separate dedicated hardware for each function.
Solution Approach 2:
The control unit acts as an intermediary that collects power consumption data from the drive motor and integrates it with the navigation system's display output. This mediator component handles the data processing and presentation layer, adding the power consumption display function without directly modifying the core navigation hardware architecture.
