摘要： A method of achieving a desired torque output of an internal combustion engine includes determining a first air-per-cylinder (APC) value based on a first APC relationship and determining a second APC value based on a second APC relationship. An APC error is determined based on the second APC value. Operation of the engine is regulated based on the first APC value when the APC error is greater than a threshold error. Operation of the engine based on the second APC value when the APC error is not greater than the threshold error.

摘要： A method and apparatus for determining the mass air flow into an internal combustion engine without the use of a mass air flow sensor. Speed density and throttle position methods of estimating mass air flow are combined using a first Kalman filter. In one aspect of the invention, the input throttle position into the throttle position mass air flow estimate is the measured throttle position obtained from the throttle position sensor. In another aspect of the invention, the input throttle position into the throttle position mass air flow estimate is the output of a second Kalman filter, which uses as its inputs the measured throttle position obtained from the throttle position sensor and the desired throttle position obtained from the pedal position sensor.

摘要： A control system includes a shift detection module, a request generation module, and a request setting module. The shift detection module detects when a transmission is executing a shift. The request generation module generates a transmission torque request to cause an engine to increase a transmission input shaft speed to a desired speed at a desired gear ratio when the transmission is executing the shift. The request setting module selectively sets the transmission torque request equal to a default torque request when the transmission torque request is greater than a first torque and the engine is coupled to a drive wheel.

摘要： A diesel oxidation catalyst (DOC) testing system includes a DOC that is located in an exhaust system of a vehicle. A control module verifies proper operation of the DOC during a post-fuel injection process in an engine of the vehicle. The control module computes a predicted temperature of exhaust gases at an output of the DOC that corresponds with proper operation of the DOC during the post-fuel injection process, determines an actual temperature of the exhaust gases during the post-fuel injection process, and activates an alarm indicator when a difference between the predicted temperature and the actual temperature is greater than a first predetermined value. A first temperature sensor is located downstream from the DOC in the exhaust system. The first temperature sensor communicates with the control module, generates the actual temperature, and transmits the actual temperature to the control module.

摘要： A method of controlling torque on a vehicle wheel axle includes comparing a torque intervention request to a predetermined minimum axle torque for a current vehicle speed and a current direction of motion of the vehicle. The predetermined minimum axle torque decreases as vehicle speed in an operator-selected direction of motion increases. An arbitrated axle torque is calculated based on an operator-requested torque, the current vehicle speed, the current direction of motion, and the greater of the torque intervention request and the predetermined minimum torque. Axle torque is applied to the vehicle's wheel axle based at least partially on the arbitrated axle torque.

摘要： A hybrid powertrain and a method of controlling a throttle in an engine of the hybrid powertrain are provided. A throttle system has a throttle at an optimal position for the engine to power a first motor/generator when an electric throttle motor is de-energized to minimize current consumption by the throttle motor. The electric throttle motor is energizable to adjust the position of the throttle. A biasing member biases the throttle to a default position when the electric throttle motor is not energized. The hybrid powertrain has a first motor/generator operatively connected to the engine, and a second motor/generator operatively connected to the generator and operable for providing output power. The engine is operable in a predetermined optimal state to provide power to the generator for powering the first motor/generator. The throttle is at a predetermined position when the engine is in the predetermined optimal state.

摘要： An engine control system comprises a torque request module, an immediate torque control module, an actuation module, and an expected torque control module. The torque request module generates an expected torque request and an immediate torque request. The immediate torque control module controls a spark advance of an engine based on the immediate torque request. The actuation module selectively reduces the expected torque request based on the immediate torque request and a spark capacity. The spark capacity is based on a difference between a first engine torque and a second engine torque, determined at a current airflow. The first engine torque is determined at a first spark advance and the second engine torque is determined at a second spark advance that is less than the first spark advance. The expected torque control module that controls a throttle valve area based on the expected torque request.

摘要： An engine system includes a throttle actuator module and a torque control module. The throttle actuator module controls a throttle actuator based on a desired throttle area. The torque control module determines an actuator torque. The torque control module determines a rate limited torque, a maximum torque, and a minimum torque based on the actuator torque and a predetermined rate of change. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is greater than the maximum torque. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is less than the minimum torque.
