Off-Road Periphery Recognition for Collision Warning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicles face challenges in periphery recognition due to the ability to approach objects from any direction and the obstruction of visual observation by uneven terrain, leading to potential collisions.
Innovation Solution
A periphery recognition support system that utilizes processing circuitry to acquire position data, determine warning conditions, and output signals to prevent collisions by recognizing peripheral objects and regulating vehicle movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If off-road vehicle travels freely off-road from any direction, then mobility and versatility are improved, but periphery recognition and collision avoidance capability deteriorate
Solution Approach 1:
The system performs preliminary detection of peripheral objects using sensors (ultrasonic, infrared, radar) before the vehicle approaches them. The processing circuitry continuously monitors position data and predicts potential collision paths in advance, allowing the driver to take preventive action before visual observation becomes necessary.
Solution Approach 2:
The patent introduces an intermediary detection system between the driver and peripheral objects. Sensors and processing circuitry act as mediators that detect objects the driver cannot see directly, converting physical presence into electrical signals and processed information that the driver can perceive through warnings and displays.
2Illumination intensity
If uneven terrain blocks visual observation, then driver's direct line of sight is improved for certain angles, but periphery recognition capability deteriorates
Solution Approach 1:
The patent replaces the mechanical visual observation system with an electronic detection system. Instead of relying on the driver's eyes and line of sight, the system uses ultrasonic sensors, infrared sensors, and radar to detect peripheral objects, processing circuitry to analyze data, and electronic warnings to convey information to the driver.
Solution Approach 2:
The detection system serves as an intermediary that bridges the gap created by terrain obstructions. Sensors positioned on the vehicle body detect objects around corners and over obstacles, transferring this information through the processing circuitry to the driver via audio or visual warnings.
3Device complexity
If driver relies on visual observation only, then system complexity is reduced, but safety and collision avoidance deteriorate
Solution Approach 1:
The patent segments the detection function into multiple independent sensor units (ultrasonic sensors at front/rear, infrared sensors, radar) rather than relying on a single complex visual system. Each sensor type detects different aspects of the periphery, and the processing circuitry integrates their outputs to provide comprehensive safety monitoring.

AI summary
A periphery recognition support system for an off-road vehicle includes processing circuitry. The processing circuitry is configured to: acquire position data indicating a position of a peripheral object around an off-road vehicle; determine based on the position data whether or not a predetermined warning condition is satisfied; and output a predetermined warning signal when it is determined that the warning condition is satisfied.
