Automatic Takeoff Headlight Signaling for Crossing Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems that perform automatic takeoff place a burden on drivers by requiring them to convey the vehicle's behavior to surroundings through lighting operations, which can be inappropriate or unnecessary.
Innovation Solution
A vehicle control device that includes an object body determination unit to detect crossing objects, a vehicle control unit to execute headlight-flashing and suspend takeoff, and a traffic signal recognition unit to prevent unnecessary headlight-flashing based on traffic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driver manually performs headlight-flashing to convey vehicle behavior, then the communication with surrounding vehicles and pedestrians is achieved, but the driver burden increases
Solution Approach 1:
The system enables the vehicle to automatically perform headlight-flashing without driver intervention. The control unit detects crossing objects and automatically activates the headlight-flashing function, allowing the vehicle to serve itself in communicating its intentions to surrounding vehicles and pedestrians.
2Productivity
If automatic takeoff control is executed without detection, then the takeoff process is efficient, but inappropriate headlight-flashing may occur in certain traffic conditions
Solution Approach 1:
The control unit continuously monitors traffic conditions including traffic signal states and preceding vehicle status. Based on this feedback, the system intelligently determines whether to execute headlight-flashing, suppressing the function when traffic signals indicate no-passage or when a preceding vehicle is stopped, thereby avoiding inappropriate lighting while maintaining takeoff efficiency.

AI summary
A vehicle control device capable of executing automatic takeoff control for automatically starting a own vehicle, the vehicle control device comprising: an object body determination unit that determines whether or not an object body that is to cross a front side of the own vehicle has been detected while the own vehicle is stopped; and a vehicle control unit that executes headlight-flashing of the own vehicle and suspends automatic takeoff of the own vehicle when the object body is detected.
