Angled Vehicle Sensor Assemblies for Close-Range Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle sensor assemblies oriented parallel to the longitudinal axis impede close-range detection of external objects.
Innovation Solution
Sensor assemblies are angled relative to the vehicle's longitudinal axis, typically between 15° to 45°, to improve object detection, with multiple sensors spaced equidistantly around the vehicle body for enhanced coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor assemblies are oriented parallel to the vehicle's longitudinal axis, then the mounting structure is simple, but the close-range detection capability is impeded
Solution Approach 1:
The patent changes the orientation angle parameter of the sensor assembly from parallel (0°) to angled (15°-45°) relative to the vehicle's longitudinal axis. This parameter change allows the sensor to detect close-range objects by directing the sensing axis downward toward the ground surface, resolving the contradiction between simple mounting and improved detection capability.
2Measurement precision
If sensor assemblies are angled relative to the vehicle's longitudinal axis, then close-range object detection is improved, but the mounting structure becomes more complex
Solution Approach 1:
The patent introduces a vertical dimension to the sensor orientation by angling the sensing axis downward from the horizontal plane. This dimensional change enables the sensor to detect objects close to the ground while maintaining a relatively simple mounting structure that accommodates the angled orientation through the defined range of 15°-45°.

AI summary
A vehicle is disclosed that includes a vehicle body and at least one sensor assembly that is supported on the vehicle body. The at least one sensor assembly is configured to detect an external object and includes a housing portion and a sensor that is supported within the housing portion such that the sensor is oriented at a fixed (e.g., downward) angle.
