ABSTRACT:
A method for controlling an engine having at least one cylinder, the engine coupled to a vehicle, the engine also having an intake manifold and an outlet control device for controlling flow from the intake manifold into the cylinder, the engine further having an inlet control device for controlling flow into the intake manifold, the outlet control device including an electronic throttle, the engine also having an exhaust gas oxygen sensor, the method comprising of generating a signal representing a request from a driver, determining a desired torque based on said request in response to said signal and to improve drive feel, adjusting the outlet control device based on said desired torque, adjusting throttle position based on an operating parameter and injecting fuel into the engine based on a signal from the sensor to maintain average air/fuel at stoichiometry.
