Abstract
A method is provided for controlling engine torque during a closed to open throttle transition in order to eliminate undesirable accelerations and oscillations from the powertrain.
Claims4
A method of controlling torque during a closed throttle to open throttle transition for an internal combustion engine, comprising the steps:
- determining a proportional error term by monitoring an amount of torque the engine will produce and is presently producing during a closed to open throttle transition;
- determining a derivative error term by monitoring a rate of change of the engine speed during a closed to open throttle transition;
- determining a torque error term as the greater of said proportional error term and said derivative error term;
- converting said torque error term to a spark compensation amount;
- and
- delivering said spark compensation amount to an engine control scheme.
