Abstract
An electronic throttle control apparatus includes a powertrain control module having at least two microprocessors. The powertrain control module is coupled to controls an internal combustion engine and an electronic throttle. A main microprocessor is located in the powertrain control module that includes control logic operative to monitor and control the internal combustion engine. A secondary microprocessor is also located in the powertrain control module and is in communication with the main microprocessor. The secondary microprocessor control throttle plate position, while interrogating the main microprocessor to verify correct execution of throttle control software in the main microprocessor. If a malfunction is detected, then the secondary microprocessor disables the internal combustion engine.
