Driver Involvement Light Emitter Layout for Autonomous Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively inform drivers about their level of involvement in surroundings monitoring during vehicle operation, particularly in self-driving modes.
Innovation Solution
A light emission device is positioned in the gaze stable or peripheral field of view of the driver, emitting light based on the driver's involvement level, with varying light patterns or colors to intuitively convey the required level of attention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the light emitter is positioned in the effective field of view of the driver, then the driver can easily see the light emission, but the light emission may distract the driver from the information display device
Solution Approach 1:
The patent positions the light emitter in the peripheral field of view rather than the central effective field of view, utilizing the spatial dimension of peripheral vision to provide visibility without causing central attention distraction. This dimensional relocation allows the light to be perceived without competing for the driver's primary focus on the information display.
2Object-affected harmful factors
If the light emitter is positioned in the peripheral field of view of the driver, then the light emission does not distract the driver from the information display, but the driver may not intuitively grasp the degree of involvement
Solution Approach 1:
The patent utilizes different light emission colors to encode different degrees of driver involvement in surroundings monitoring. By assigning specific colors to different involvement levels, the system conveys critical information through color perception in the peripheral field of view, compensating for the reduced attentional focus while maintaining intuitive information transmission.
3Duration of action of stationary object
If the light emitter emits continuous light, then the information is always visible, but the driver may not notice changes in the degree of involvement
Solution Approach 1:
The patent employs periodic blinking or pulsing light emission patterns to indicate changes in the degree of driver involvement. This temporal modulation creates noticeable variations that draw the driver's attention to changes in involvement level, while maintaining overall continuous presence through repeated emission cycles, thus balancing persistence with detectability of changes.

Data Source
AI summary
A light emission device is installed in a vehicle capable of changing a degree of involvement of a driver in surroundings monitoring during driving. A light emitter is configured to be located in a gaze stable field of view of the driver when an information display device is located in an effective field of view of the driver. The information display device is disposed on a side of a steering device in the mobile entity. The light emitter is configured to emit light in a manner according to the degree of involvement of the driver in the surroundings monitoring during driving.
