US Patent 7162339 automated vehicle calibration and testing system via telematics

Methods and apparatus are provided for automatically updating the calibration parameters of a vehicle from a remote location. The apparatus typically comprises an onboard computing platform connected to electronic control units in the vehicle. The computing platform is typically pre-programmed with initial vehicle calibration parameters for downloading to the electronic control units. A remote calibration data system is generally configured to acquire vehicle performance data via a wireless communication link, and to update the vehicle calibration parameters based on statistical analysis of the acquired data. The updated calibration parameters are then typically transmitted by the remote calibration data system to the computing platform via the communication link. The computing platform can then download the updated calibration parameters to the electronic control units. The automatic updating process described herein is generally applicable to a population of appropriately equipped vehicles in communication with a centralized remote calibration data system.
