Abstract
A system includes a tire pressure monitoring system (TPMS) module coupled with a wheel on a vehicle and a vehicle navigation system of the vehicle. A method entails determining a movement signal at the TPMS module and receiving the movement signal at the vehicle navigation system. The vehicle navigation system includes an inertial sensor system configured to supply motion signals indicative of motion of the vehicle and the vehicle navigation system determines output data in response to the motion signals. The vehicle navigation system output data is calibrated at the vehicle navigation system by utilizing movement signals from the TPMS module to remove an error component from the vehicle navigation system output data. Thus, calibration can be performed in lieu of or in addition to utilizing signals from satellites, which may not be available at all times.
