Abstract: A method for an accelerator pedal safety in a vehicle with an internal combustion engine having an Electronic Control Unit, (ECU), said method comprising: starting the engine; determining whether the engine is running; determining whether there is a request for additional torque; determining whether an inhibit is enabled; determining whether the vehicle speed is above a preset threshold; enabling the accelerator pedal torque request; and, logging a fault in the ECU and enabling the appropriate lamps or visual fault indicators.

Abstract: A real-time maintenance alert system for use in a heavy duty truck having an engine including an engine controller having a communications data link is provided. The system includes an engine item sensor and a non-engine item sensor. Control logic at the engine controller produces an output signal at the data link in response to the presence of an engine item real-time fault condition. A display device transmits and receives information over the data link, and processes the control logic output signal. The display device generates an output signal indicative of the engine item status. Further, the display device directly receives and processes the non-engine item sensor output signal, and generates an output signal indicative of the non-engine item status.

Abstract: A method for controlling a vehicle including an internal combustion engine having an idle speed includes controlling the idle speed based on system voltage, and increasing the idle speed when system voltage is low and the vehicle speed status indicates that the vehicle is stationary. In some embodiments, idle speed may ramp up with current demanded engine speed while the vehicle is moving.

Abstract: A method of controlling a turbocharger in an internal combustion engine includes monitoring a turbocharger parameter such as turbine speed or turbo boost pressure, and establishing a turbocharger parameter limit value for the turbocharger parameter. A dynamic engine torque limit value is determined based on the current value of the turbocharger parameter and the turbocharger parameter limit value. A provisional engine torque is based on engine conditions, and an applied or desired engine torque is limited to the lesser of the dynamic engine torque limit value and the provisional engine torque.

Abstract: A real-time maintenance alert system and method for use in a heavy-duty truck having an engine controller with memory are provided. The system includes a sensor operative to indicate an engine condition from the group consisting of: oil filter restriction, air filter restriction, fuel filter restriction, oil level, and coolant reserve tank fluid level. Control logic at the engine controller processes the sensor signal to determine a real-time fault condition, when appropriate.
