Guide Vehicle Blind-Spot Sensing Before Autonomous Leading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicles face challenges in ensuring comprehensive safety around the vehicle due to blind spots created by sensor arrangements, leading to insufficient safety confirmation in regions behind, on the sides, and under the vehicle.
Innovation Solution
A moving body equipped with sensors such as LiDAR, cameras, and radars senses the region around the vehicle before leading it, ensuring complete coverage and using different types of sensors to enhance accuracy and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are arranged on the vehicle to detect obstacles, then obstacle detection capability is improved, but blind spots remain in regions behind, on sides, and under the vehicle
Solution Approach 1:
The patent introduces a moving body as an intermediary that carries sensors to detect obstacles in blind spot regions. The moving body positions itself strategically (behind, beside, or under the vehicle) to capture areas that fixed vehicle-mounted sensors cannot reach, thereby eliminating blind spots and improving overall safety confirmation.
Solution Approach 2:
The patent adds a spatial dimension to obstacle detection by deploying a mobile sensing platform rather than relying solely on fixed sensors on the vehicle. This dimensional change allows coverage of previously inaccessible regions around the vehicle, particularly blind spots behind and under the vehicle.
2Adaptability or versatility
If a moving body leads the vehicle autonomously, then vehicles without complete autonomy can be guided safely, but additional sensing and control systems are required
Solution Approach 1:
The moving body is designed with multi-functionality, serving both as an autonomous guide vehicle and as a mobile sensor platform for detecting blind spots. This universal design allows the same system to support vehicles with varying levels of autonomy while simultaneously performing safety confirmation functions.
Solution Approach 2:
The moving body performs self-positioning and self-navigation to reach optimal sensing locations around the vehicle. By autonomously determining its own position and movement, the system reduces the complexity of external control mechanisms while maintaining the ability to guide non-autonomous vehicles safely.

AI summary
A moving body capable of autonomously traveling and having a function of leading a first vehicle that travels while following the moving body, the moving body comprises a first sensor that detects an obstacle; and a controller configured to execute sensing of a region around the first vehicle by the first sensor before the moving body starts leading the first vehicle.
