Autonomous Vehicle Sensor Measurement for Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face an increased risk of collision when attempting to convey larger objects in limited spaces due to their smaller size, particularly when navigating around obstacles.
Innovation Solution
The autonomous vehicle is equipped with a docking mechanism, sensors such as a ToF camera for object position data acquisition, and a controller to manage conveyance, ensuring safe navigation and collision avoidance by adjusting its path based on sensor data, including an area above the vehicle in its measurement range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the autonomous vehicle reduces its size to navigate limited spaces, then it can move in confined areas such as living rooms, but the possibility of collision between the conveyance target and obstacles increases
Solution Approach 1:
The patent extends the sensor measurement range to include the area above the autonomous vehicle (vertical dimension), not just the horizontal plane. This dimensional expansion allows the vehicle to detect obstacles that may be overhead or approaching from above, thereby reducing collision risk while maintaining its compact size for navigating limited spaces
2Device complexity
If the autonomous vehicle uses a small sensor measurement range, then the device complexity is reduced, but the ability to detect obstacles in the conveyance path is insufficient
Solution Approach 1:
The patent expands the sensor measurement range to include the vertical dimension (area above the vehicle), providing comprehensive obstacle detection without requiring multiple separate sensing systems. This dimensional approach improves detection capability while maintaining relatively simple device architecture

AI summary
An autonomous vehicle with a reduced risk of collision during conveyance is provided. The autonomous vehicle docks with a conveyance target and conveys the conveyance target. The autonomous vehicle includes a docking mechanism configured to dock with the conveyance target, a sensor configured to acquire object position data related to a position of an object within a measurement range, and a controller configured to control, based on the object position data acquired from the sensor, the conveyance performed by the autonomous vehicle docked with the conveyance target. The measurement range of the sensor includes at least an area above the autonomous vehicle.
