Vehicle Display Device Anticipating Traveling Mode Switches
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers of hybrid vehicles are not informed about future changes in vehicle traveling modes, which hinders their ability to optimize fuel economy and energy conservation.
Innovation Solution
A display device and method for hybrid vehicles that provides drivers with information on future traveling mode switches by dividing routes into segments and associating each segment with a specific traveling mode, allowing the driver to anticipate and adjust for energy-efficient driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the vehicle automatically switches between traveling modes (normal/economical or HV/EV) based on power availability and route analysis, then fuel economy and energy efficiency are improved, but the driver loses awareness of future mode changes and cannot optimize driving behavior accordingly
Solution Approach 1:
The system performs preliminary analysis of the travel route to identify mode switching points before the driver reaches them. The display device shows future mode change information in advance, allowing the driver to prepare for upcoming transitions between EV and HV modes, thereby optimizing driving behavior and energy consumption.
Solution Approach 2:
The system provides continuous feedback to the driver about current and future traveling modes through the display device. By showing mode switching points and upcoming mode changes, the system creates a feedback loop that keeps the driver informed, enabling them to adjust driving behavior to match the vehicle's energy management strategy.
2Loss of information
If the system provides detailed information about future mode switches and route segments, then driver awareness and energy conservation improve, but the device complexity and information processing requirements increase
Solution Approach 1:
The travel route is divided into segments with distinct mode switching points. The display device presents information in a segmented format, showing only the relevant mode change information for upcoming segments rather than overwhelming the driver with complete route details. This segmentation simplifies the information presentation while maintaining comprehensive analysis capabilities.

AI summary
A vehicle has a plurality of traveling modes. A display device for the vehicle comprises: a display unit (48) displaying map information; and a control unit (14) causing the display unit (48) to display recognizably, at a portion of roads in the map information, traveling modes that correspond to the roads. Preferably, the control unit (14) sets a destination in response to an instruction received from an operator, searches for a traveling route extending from a starting point to the destination, divides the traveling route into segments, and associates one of the traveling modes with each of the segments. More preferably, the control unit (14) causes the display unit (48) to display the plurality of candidate traveling routes, each with the traveling mode overlaid thereon, and selects in response to an instruction of the operator one traveling route planned to be taken among the plurality of candidate traveling routes.
