ABSTRACT
The computer is the central control component in the vehicle. It performs some of the control algorithms, monitors all subsystems for failure, and determines the overall operating strategy for the vehicle, which in large part with the component efficiency determines the efficiency of the vehicle
Table 4 summarizes the channel inputs, items read, and types of signals. As controller algorithms change, it may be necessary to adjust what is being monitored. For example, if an open loop engine controller is developed to the point where the confidence level is high, the engine speed would not be necessary. In addition, the engine temperature, once the vehicle configuration and cooling system is tested, would not be needed. The gauges mounted on the dashboard could monitor these items, along with the engine control module (ECM).
