Abstract

A system for monitoring and the adjustment of control unit parameter settings of vehicle electronic control units (44, 45).
The monitoring system may be implemented in a vehicle (12, 14) in which are incorporated one or more electronic control units (44, 45) for regulating one or more operational parameters of the vehicle (12, 14) in accordance with corresponding control unit parameter settings. In an exemplary implementation the vehicle (12, 14) is equipped with a mobile communications terminal, MCT (38), which receives from a base station (18) a list of operational parameters to be monitored. Each of the electronic control units (44, 45), as well as a memory unit (62), are connected to an internal data link (40) of the vehicle. When a parameter value within the memory unit (62) corresponding to a given electronic control unit (44, 45) is changed, a message is provided to the base station (18) specifying the value currently registered by the particular electronic control unit (44, 45). 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 electronic control unit parameter settings to be adjusted from a remote location such as a base station (18).
