AI Technical Summary
Traditional methods for detecting vehicle body pitch angle cannot adapt to different vehicle wheelbases, resulting in large detection errors and failing to provide accurate vehicle body pitch angle data, which affects vehicle handling, stability, and ride comfort.
A detection device comprising a main frame, guide beam, load-bearing carriage, fixing components, and detection components was designed. Through adjustable fixing components and a non-contact laser probe, the wheel can be precisely fixed according to the wheelbase of different vehicles and flexibly adjusted to adapt to different vehicle models and detection scenarios.
It enables precise detection of vehicle body pitch angle, reduces detection errors, provides a reliable basis for optimizing vehicle handling, stability and ride comfort, and improves the flexibility and versatility of the detection.
