AI Technical Summary
Existing technologies struggle to accurately capture information about road irregularities, especially when using inexpensive forward-looking sensors. This results in inaccurate responses from the suspension control system in preemptive states, making it difficult to effectively control the adaptive dampers.
By combining unsprung mass accelerometers and GPS with forward-looking sensors, and through preemptive road event classification and threshold-based pre-triggering mechanisms, the damping settings of the suspension system are monitored and adjusted in real time. Accurate road event prediction and response are achieved using unsprung mass acceleration data and vehicle position data.
It improves ride comfort and road safety of the suspension system without increasing hardware costs, and optimizes the performance of the suspension control system through fast response time and accurate road event detection.
