摘要: Internal combustion engine control is generally in accordance with RPM and torque modes. Transition from RPM to torque control is accomplished by employing a mass airflow term accounting for any nonequivalence between RPM mode and torque mode mass airflows corresponding respectively to an RPM mode mass airflow and a closed-throttle mass airflow contribution to a total torque mode mass airflow.

摘要: An engine control module comprises a base reserve module, a power steering reserve module, a reserve torque module, first and second engine actuator modules, and an engine speed control module. The base reserve module determines a base reserve torque. The power steering reserve module determines a power steering reserve torque. The reserve torque module determines a first reserve torque based on the base reserve torque, the power steering reserve torque, and at least one of an oil temperature of an engine and a barometric pressure. The first and second engine actuator modules control first and second actuators of the engine, respectively. The engine speed control module instructs the first engine actuator module to produce a first torque output from the engine and instructs the second engine actuator module to produce a second torque output from the engine.

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.
