Abstract

A system for monitoring and adjustment of control unit parameter settings of vehicle electronic control units. The monitoring system may be implemented in a vehicle in which are incorporated one or more electronic control units for regulating one more operational parameters of the vehicle in accordance with corresponding control unit parameter settings. In an exemplary implementation the vehicle is equipped with a mobile communications terminal (MCT), which receives from a base station a list of operational parameters to be monitored. Each of the electronic control units, as well as a memory unit, are connected to an internal data link of the vehicle. When a parameter value within the memory unit corresponding to a given control unit is changed, a message is provided to the base station specifying the value currently registered by the control unit. The currently registered value is then compared to an expected parameter value, and an error message is generated if disagreement exists therebetween. The system also allows vehicle control unit parameter settings to be adjusted from a remote location such as a base station. The MCT of each vehicle is disposed to generate message packets containing updated control unit parameter information received from the base station. The message packets are then sent to a selected electronic control unit over the data link, thereby allowing the updated control unit parameter information to be loaded therein.
