Vehicle Radar Mount Adjustment for Body Tilt Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-mounted radar systems fail to adaptively adjust their horizontal angle in response to changes in the vehicle body's tilt, leading to reduced accuracy due to fixed mechanical angles and limited software compensation.
Innovation Solution
A vehicle-mounted radar adjusting device with a first and second mounting plate, where the second plate is adjustable via an adjusting assembly and a controller to rotate in a horizontal direction, allowing for automatic angle adjustments based on detected changes in the radar's angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the mechanical angle of vehicle-mounted radar is fixed after being loaded, then the installation structure is simple and stable, but the radar cannot adaptively adjust the horizontal angle when the vehicle body tilts, reducing measurement precision
Solution Approach 1:
The patent transforms the fixed mechanical angle structure into a dynamic adjustable one by introducing an adjusting assembly with a rotating mechanism. The second mounting plate can rotate relative to the first mounting plate around a horizontal axis, allowing the radar's mechanical angle to change dynamically in response to vehicle body tilt, thereby improving measurement precision while maintaining manageable device complexity through modular design
Solution Approach 2:
The patent implements a feedback control system where the controller receives signals about the vehicle body tilt state and automatically controls the adjusting assembly to rotate the second mounting plate, compensating for the tilt angle. This closed-loop feedback mechanism ensures the radar maintains accurate horizontal angle measurement despite vehicle body changes, resolving the contradiction between precision and complexity
2Reliability
If the compensated angle range of the software is reduced, then the processing complexity is lowered, but the radar cannot adaptively adjust when the vehicle body is fully loaded, worsening reliability
Solution Approach 1:
The patent enables the radar system to self-adjust by integrating the adjusting assembly directly into the mounting structure. The controller automatically activates the rotating mechanism based on detected vehicle body tilt, allowing the system to compensate for load-induced tilts without external intervention. This self-service capability improves reliability under varying load conditions while keeping the control system relatively simple through automated operation
