Abstract :
Modern telematics devices use MEMS sensors to provide new features such as characterization of driving events and crashes. Accurate reporting requires information on device to vehicle frame misalignment. Paper provides a simple method for in-motion azimuth alignment of a consumer grade inertial measurement unit. Testing is done using real vehicle in regular urban driving conditions. Presented methods estimate azimuth angle with standard deviation better than 1°.
