Mining Transporter Vehicle Collision Control via Dynamic Deceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision prevention systems for transporter vehicles in mining sites excessively limit traveling operations, potentially degrading work efficiency while attempting to prevent collisions, which can lead to increased damage risks.
Innovation Solution
A transporter vehicle equipped with a state detection system, object detection system, and a collision determination unit that adjusts deceleration based on the vehicle's loading state, calculating required stop distances and times to minimize collision risks while maintaining operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the traveling operation of the transporter vehicle is excessively limited to prevent collision with detected objects, then collision damage is reduced, but work efficiency is degraded
Solution Approach 1:
The system dynamically changes the deceleration parameter based on the loading state of the vehicle. When the vehicle is loaded, a smaller deceleration is applied to maintain work efficiency, while when empty, a larger deceleration is applied to prevent collisions. This parameter adaptation resolves the contradiction by adjusting the prevention intensity according to the actual risk level.
2Reliability
If the deceleration is increased to prevent collision, then collision damage is reduced, but the vehicle stops more frequently affecting productivity
Solution Approach 1:
The deceleration parameter is changed based on the loading state detection. When the vehicle is in a loaded state, the system applies a smaller deceleration value, allowing the vehicle to maintain motion longer and reduce unnecessary stops. When empty, a larger deceleration is applied. This dynamic parameter adjustment reduces unnecessary stopping time while maintaining adequate collision prevention.

AI summary
A transporter vehicle includes: a vehicle; a vessel that is provided in the vehicle; a traveling state detection device that detects a traveling state of the vehicle; an object detection device that detects an object in front of the vehicle; and a collision determination unit that determines a possibility of collision with the object based on a loading state of a load of the vessel, a detection result of the traveling state detection device, and a detection result of the object detection device.
