Abstract:
A control system for controlling a diesel engine powering a motor vehicle comprising:a processor programmed to provide a preset value of maximum allowable engine torque data that is processed for control of the engine during non-occurrence of a vehicle event that would otherwise call for changing the preset value to a different value; a first data source providing data defining a current maximum limit for fueling the engine; a second data source providing data defining a torque request for the engine; a third data source providing data distinguishing between the occurrence and non-occurrence of a vehicle event calling for change in the value of the maximum allowable engine torque data from the preset value to a different value; wherein when the third data source data indicates occurrence of a vehicle event calling for change in the value of the maximum allowable engine torque data from the preset value to a different value, the processor processes the data from the first data source and the data from the second data source to develop data that is then processed by the processor as the value of the maximum allowable engine torque data instead of the preset value.
