    摘要： A system and method for controlling a multi-cylinder internal combustion engine include determining a currently available maximum torque, determining a driver demanded torque based on a current accelerator pedal position and reference ambient conditions, and controlling the engine to deliver the lesser of the driver demanded torque corresponding to the reference ambient conditions and a calibratable percentage of the currently available maximum torque corresponding to the current ambient conditions. A similar torque is provided at high altitudes as that provided at sea level for a given low pedal position while smoothly blending into the currently available peak torque.

    摘要： A speed control method for vehicles having an internal combustion engine smoothly controls engine torque to control vehicle speed. Torque is controlled via airflow in a first torque control range. Torque is controlled via a coordination of air/fuel ratio, ignition timing, and cylinder deactivation is a second torque control range. The torque range is selected based on the required airflow to deliver the required torque. If the required airflow is less than a lower allowable value, then the airflow is fixed at this lower allowable value and the second range is selected. Otherwise, the first range is selected.
