AI Technical Summary
In existing autonomous driving engineering vehicle steering systems, there is a lack of effective real-time monitoring methods when the steering pump or hydraulic accessories fail, leading to potential fatal dangers. Furthermore, redundant backup systems increase system complexity and waste resources.
Pressure and flow sensors are installed at the oil inlet and outlet of the steering gear mechanical body. The controller monitors the pressure and flow data of the steering system in real time, and uses interpolation tables and comparison algorithms to determine the working status of the steering system, detect abnormalities in a timely manner, and take protective measures.
It enables real-time monitoring of the steering system, timely detection of anomalies and implementation of parking protection measures, avoiding the risk of steering failure and reducing system complexity and resource waste.
