Vehicle Sensor Tester Mounting for Full Field-of-View Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sensor testing systems do not allow for efficient field of view testing without additional fix points, leading to inefficiencies in verifying the correct functioning of vehicle sensors, especially in advanced driver assistance systems or autonomous vehicles.
Innovation Solution
A system comprising a tester and a holding arrangement, where the holding arrangement is mounted on the vehicle to hold the tester at a certain distance in front of the sensor, allowing for enhanced field of view testing through movable or repeatable azimuth movement, and can be directly attached to the vehicle's wheels or frame, with a rigid design to simplify installation and reduce complexity.

Engineering Contradiction Analysis
1Area of stationary object
If a traditional vehicle sensor testing system is used, then the testing can be performed, but the field of view coverage is limited and additional fix points are required
Solution Approach 1:
The patent combines the tester positioning function with the vehicle's existing wheel structure. The holding arrangement is mounted on the wheel, merging the testing apparatus with a component that naturally provides both support and rotational movement capability, thereby achieving full field of view coverage without additional fix points
Solution Approach 2:
The wheel serves multiple functions: it supports the holding arrangement, provides rotational movement for azimuth coverage, and acts as a mounting base. This multi-functional use of the wheel eliminates the need for separate fix points while achieving complete field of view testing
2Device complexity
If the holding arrangement is made rigid and directly mounted to the vehicle, then the device complexity is reduced, but the ability to cover full field of view may be limited
Solution Approach 1:
The holding arrangement is mounted on the wheel, which provides dynamic rotational capability. This allows the tester to move azimuthally as the wheel rotates, enabling full field of view coverage while maintaining a simple rigid structure that is directly mounted to the vehicle

AI summary
A system for testing an emitting sensor of a vehicle is provided. Said system comprises a tester for testing the sensor, e.g. by simulating a target for the sensor's emission, and a holding arrangement, especially a holder, for holding the tester. In this context, the holding arrangement is adapted to be mounted on the vehicle and to hold the tester at a certain distance in front of the sensor.
