    摘要: A system for detecting contamination of an air filter for an internal combustion engine includes an air pressure sensor disposed downstream of the air filter, an air flow sensor disposed in an air intake system of the engine, and a control module in communication with the air pressure sensor and the air flow sensor. The control module is configured to estimate an atmospheric pressure based on a signal received from the air pressure sensor. The control module is further configured to determine a contamination level of the air filter based on an air flow rate provided by the air flow sensor and a pressure drop across the air filter based on a pressure difference between the estimated atmospheric pressure and a second pressure measurement from the air pressure sensor that corresponds to the provided air flow rate.

    摘要: An engine control module comprises a torque control module, an engine speed (RPM) control module, and an actuator module. The torque control module determines a first desired torque based on a requested torque. The RPM control module selectively determines a second desired torque based on a desired RPM. The torque control module determines the first desired torque further based on the second desired torque when the engine control module is transitioning from an RPM control mode to a torque control mode. The RPM control module determines the second desired torque further based on the first desired torque when the engine control module is transitioning from the torque control mode to the RPM control mode. The actuator module controls an actuator of an engine based on the first and second desired torques.
