Vehicle Sensor Layout for Wide-Area Peripheral Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detecting apparatuses for vehicles, such as those used in commercial trucks, require multiple sensors to cover a wide detection range, leading to inefficiencies and potential obstructions in design and performance.
Innovation Solution
A detecting apparatus with a front-side detection section and a side detection section, both inclined to optimize detection ranges, covering the vehicle's periphery without obstructing the truck bed, and a calculating section to determine object positions.

Engineering Contradiction Analysis
1Area of stationary object
If multiple detecting apparatuses are disposed to cover a wide detection range, then the detection coverage is improved, but the device complexity increases
Solution Approach 1:
The detection system is divided into multiple detection sections (front-side detection section and side detection section), each with specific detection ranges. By segmenting the detection coverage into distinct zones handled by different sensors, the system achieves wide-area monitoring while using a minimal number of detecting apparatuses.
Solution Approach 2:
The detecting apparatuses are disposed in different spatial locations (front portion and side portions of the vehicle) with different orientation angles. This spatial and angular arrangement allows a small number of sensors to cover a wide three-dimensional detection range, effectively using dimensional positioning to expand coverage without increasing sensor quantity.
2Reliability
If detecting apparatuses are disposed on the vehicle, then object detection capability is improved, but obstruction to the truck bed design occurs
Solution Approach 1:
The detecting apparatuses are disposed at specific locations (front portion and side portions of the vehicle body) rather than uniformly distributed. This localized placement ensures detection coverage while avoiding interference with the truck bed structure and design, allowing the truck bed to be configured independently without obstruction.

AI summary
Disclosed are: a detecting device that efficiently detects objects present around a vehicle; and a detection position calculating device. The detecting device includes: a forward detecting unit that is disposed in the proximity of a front portion of one side portion of a pair of side portions of a cab disposed at a front portion of a vehicle, and that detects an object present in a detection range spreading to the front of a detecting face facing forward from the vehicle; and a side detecting unit that is disposed in the proximity of a rear portion of one side portion of the cab, and that detects an object present in a detection range spreading to the front of a detecting face facing sideways from the vehicle. The forward detecting unit is disposed with the detecting face inclined toward one side portion side as to an orthogonal line orthogonal to a center axis of the vehicle, and the side detecting unit is disposed with the detecting face inclined toward a rear of the vehicle as to the center axis.
