Save Your Drive : Vehicle Health Monitoring System

A vehicle health monitoring system based on analytical redundancy is developed for automated passenger vehicles. A residual generator and a residual processor are designed together to detect and identify actuator and sensor faults of the Buick LeSabre rapidly. The residual generator includes fault detection filters and parity equations. It uses the control commands and sensor measurements to generate the residuals, which have a unique static pattern in response to each fault. Then, the residual processor interrogates the residuals by matching them to one of several known patterns. It computes the probability of each hypothesis conditioned on the history of residuals. The vehicle health monitoring system is evaluated in real-time on a Buick LeSabre. The vehicle sensor and actuator faults are simulated artificially by the computer or created manually by the driver. In one experiment, a real intermittent sensor fault occurred and was immediately detected and identified. The real-time evaluation demonstrates that the vehicle health monitoring system can detect and identify actuator and sensor faults under various disturbances and uncertainties with almost minimal detection latency.

Save time and use the Vehicle Health Monitoring System to monitor and translate your vehicle issues. Simply plug the sensor into your car’s OBD-II port, download the free app to your iPhone or Samsung Galaxy/Android smartphone then connect the sensor via Bluetooth. The app will diagnose and translate your car problems into simple non-technical terms you can understand. It can also clear your check engine light and give maintenance price estimates. Connect multiple smartphones to the device to monitor multiple vehicles simultaneously.
