In-Vehicle Control Device Electric Traveling Area Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle control devices do not provide a notification to drivers when it is not possible to complete an electric traveling area by electric traveling due to the remaining battery amount, leading to potential misconceptions about the feasibility of electric traveling.
Innovation Solution
An in-vehicle control device that displays an electric traveling setting area and an electric traveling possible area on a map using different display methods, allowing drivers to determine if the electric traveling area can be completed by electric traveling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the system displays only the electric traveling setting area without indicating the electric traveling possible area, then the display is simple and easy to understand, but the driver cannot determine whether the electric traveling area can be completed by electric traveling
Solution Approach 1:
The display is segmented into two distinct visual representations: the electric traveling setting area (target area) and the electric traveling possible area (achievable area). By dividing the information into separate visual elements with different display methods, the system provides complete information about electric traveling feasibility without creating a confusing unified display.
Solution Approach 2:
The system uses different display methods (such as different colors or visual styles) to represent the electric traveling setting area and the electric traveling possible area. This visual differentiation allows drivers to immediately understand the relationship between the target area and the achievable area, clearly indicating whether the setting area can be completed by electric traveling.
2Adaptability or versatility
If the system allows setting an electric traveling setting area wider than the electric traveling possible area, then the user has flexibility in setting, but the driver may mistakenly believe that the electric traveling area can be completed
Solution Approach 1:
The system performs preliminary calculation of the electric traveling possible area based on the current battery state before the driver finalizes the setting. By displaying both the setting area and the possible area in advance, the system allows drivers to adjust their settings to match realistic capabilities, preventing misconceptions about electric traveling feasibility.
Solution Approach 2:
The system provides visual feedback by displaying both the electric traveling setting area and the electric traveling possible area simultaneously. This feedback mechanism allows drivers to understand the relationship between their desired setting and the actual achievable area, enabling them to make informed adjustments to ensure the setting area can be completed by electric traveling.

AI summary
An in-vehicle control device is mounted on a vehicle that includes an engine, a motor for traveling, a battery configured to supply electric power to the motor, and map information, and that is configured to perform electric traveling. The in-vehicle control device includes a processor. The processor is configured to display an electric traveling setting area, in which the vehicle performs electric traveling, on the map information using a first display method. The processor is configured to display an electric traveling possible area, in which the vehicle is able to perform electric traveling, on the map information using a second display method different from the first display method.
