Cabin Illumination Cues for Low Emission Zone EV Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles do not effectively sensorily notify drivers of entering a low emission zone, relying solely on text messages which may be overlooked.
Innovation Solution
Equipping vehicles with an illumination device in the cabin that changes luminescence patterns to signal entry into a low emission zone, using LEDs on the instrument panel, doors, and ceiling, with controlled color and brightness changes to alert the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If text message display is used to notify driver of LEZ entrance, then information can be transmitted to driver, but driver awareness and sensory recognition are insufficient
Solution Approach 1:
The illumination device changes color (from first color to second color) to provide visual notification of LEZ entrance. This color change creates a noticeable sensory cue that captures driver attention and effectively communicates the zone entry without requiring complex display systems or multiple notification components.
Solution Approach 2:
The illumination device performs blinking or flashing operations to create dynamic visual notification. This temporal variation in illumination intensity enhances driver perception and ensures the notification is noticed, transforming a static text message into an active sensory alert without adding mechanical vibration components.
2Loss of information
If illumination device luminescence is changed to notify driver, then driver sensory recognition is improved, but energy consumption increases
Solution Approach 1:
The illumination device uses periodic blinking or flashing actions rather than continuous illumination. This periodic action maintains effective driver notification while significantly reducing overall energy consumption compared to sustained high-intensity lighting, as the illumination is activated only during critical notification moments.
Solution Approach 2:
The system changes illumination parameters (color temperature, intensity, blinking frequency) based on the notification requirement. By adjusting these parameters dynamically rather than maintaining constant high-level illumination, the system achieves effective driver alertness with optimized energy utilization.

AI summary
A vehicle is a vehicle that is equipped with an illumination device in a vehicle cabin and that is capable of traveling in an EV mode, the vehicle being configured to change a manner of luminescence of the illumination device when the vehicle enters a low emission zone (LEZ) where the vehicle needs to travel in the EV mode, and to cause a driver to perceive the entrance. For the change in the manner of the luminescence, for example, the color of the luminescence of the illumination device may be changed from a regular color to a specific color. By the change in the manner of the luminescence of the illumination device, it is possible to cause the driver to sensorily recognize the entrance to the low emission zone.
