Heavy-Duty Vehicle Hazard Light Control for Speed and Angle Risks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers of heavy-duty vehicles face challenges in determining when to activate and deactivate hazard lights, which can lead to increased accident risk due to the non-standardized location of hazard light switches and difficulty in assessing the need for warnings.
Innovation Solution
A computer-implemented method that automatically controls vehicle hazard lights based on speed limit intervals and traveling angles, activating them when the vehicle's speed and angle are outside predetermined ranges, and deactivating them when conditions improve.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hazard light switch location is not standardized, then driver flexibility is improved, but driver response time worsens
Solution Approach 1:
The system automatically detects hazardous conditions and controls hazard lights without driver intervention. The processor monitors vehicle speed, compares it to speed limit data, determines when hazard lights should be activated, and controls them automatically, eliminating the need for the driver to locate and operate the switch.
2Loss of time
If automatic control of hazard lights is implemented, then warning timeliness is improved, but system complexity worsens
Solution Approach 1:
The system leverages existing multi-functional components already present in modern vehicles. The processor utilizes existing sensor data (speed sensors, GPS, cameras) and integrates with the vehicle's existing hazard light control system, rather than creating entirely new dedicated components. This approach adds automatic hazard light control functionality while minimizing additional system complexity.

AI summary
A computer-implemented method for warning road users of a hazardous operating condition of a heavy-duty vehicle. The method comprises obtaining, by a processor device of a computer system, a speed limit interval associated with a road on which a heavy-duty vehicle is travelling, and wherein the speed limit interval is based on a speed limit of the road; determining, by the processor device, that a travelling speed of the heavy-duty vehicle is outside the speed limit interval; determining, by the processor device, that a travelling angle of the heavy-duty vehicle and/or of the road on which the heavy-duty vehicle is travelling is outside a predetermined travelling angle range; and automatically controlling, by the processor device, the vehicle hazard lights of the heavy-duty vehicle based on the travelling speed and the travelling angle.
