    摘要: A control system for an engine includes an engine torque request module, an engine torque response module, a torque command limit module, and an actuation module. The engine torque request module determines an engine torque request based on (i) an engine power request and (ii) a desired engine speed (DRPM). The engine torque response module determines first and second torque values based on (i) an engine torque response model and (ii) first and second torque boundaries, wherein the first and second torque boundaries are based on the DRPM and a measured engine speed (RPM). The torque command limit module generates a secured engine torque request based on (i) the engine torque request and (ii) the first and second torque values. The actuation module controls at least one actuator of the engine based on the secured engine torque request.

    摘要: A system for a vehicle includes a desired mass air flowrate (MAF) module and a desired effective area module. The desired MAF module generates a desired MAF through a throttle valve of an engine based on an engine torque request. The desired effective area module generates a desired effective area of the throttle valve based on a throttle inlet air pressure (TIAP) and the desired MAF. A throttle actuator module adjusts opening of the throttle valve based on the desired effective area.

    摘要: A control system for a vehicle includes a communication module and a vehicle stop module. The communication module receives a command from a vehicle services provider (VSP) to decrease a speed of the vehicle to a desired speed, wherein the VSP is located remotely with respect to the vehicle. In response to the received command, the vehicle stop module decreases the speed of the vehicle to the desired speed by controlling at least one of a transmission, an electronic parking brake, and electronically assisted brakes.

    摘要: A fault clearing system and method for an engine control system includes a plurality of processor modules to control and monitor the engine and set a plurality of faults. The plurality of processor modules includes an electronic throttle control (ETC) module to control and monitor a throttle of the engine, and a plurality of engine sensors and ETC sensors. An ETC diagnostic module monitors the ETC sensors and engine sensors, with the ETC diagnostic module setting a low voltage induced fault. The ETC diagnostic module will also enter one of a plurality of low voltage states in response to the low voltage induced fault. The ETC diagnostic module selectively controls the ETC module and selectively clears the faults in the ETC module and plurality of processor modules upon entry into one of the low voltage states.
