Vehicle Lighting Control for Start Intention Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle notification systems for indicating the start of a vehicle are costly and complex, requiring additional devices to be mounted on the vehicle for optical notifications on the road surface.
Innovation Solution
A notification apparatus mounted on a vehicle that includes a detector to sense the driver's intention to start the vehicle and a lighting controller to activate the vehicle's lighting in a specific mode, such as blinking, to notify the surroundings without additional road-mounted devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device that draws an optical start notification display on the road surface is mounted on the vehicle, then the notification effectiveness is improved, but the vehicle cost increases
Solution Approach 1:
The patent applies multi-functionality by making the existing lighting device serve dual purposes: its original function (illumination) and a new function (start notification). The lighting controller enables the lighting device to operate in different modes - normal illumination mode and notification mode with predetermined patterns - thereby eliminating the need for separate notification devices and reducing vehicle cost while maintaining notification effectiveness
Solution Approach 2:
The patent merges the notification function with the existing lighting device by integrating a lighting controller that coordinates both functions. The control unit combines the illumination control and notification pattern control into a single system, allowing the lighting device to simultaneously or alternatively perform both illumination and start notification tasks, thus avoiding additional hardware costs
2Illumination intensity
If a device that draws an optical start notification display on the road surface is mounted on the vehicle, then the visibility of vehicle start is improved, but the device complexity increases
Solution Approach 1:
The lighting controller enables the existing lighting device to perform multiple functions - normal illumination and start notification with predetermined patterns. By making the single lighting device multi-functional, the patent avoids adding separate notification devices, thereby maintaining high visibility of vehicle start while preventing an increase in device complexity
Solution Approach 2:
The control unit merges the control of illumination and notification patterns into a single integrated system. The lighting controller coordinates the lighting device to switch between normal illumination mode and notification mode with predetermined patterns, combining multiple functions into one control mechanism and avoiding the complexity of separate control systems
