Automotive engine control method
An engine control method for an automotive vehicle includes the steps of gathering and analyzing vehicle condition parameters from a vehicle condition detecting means, determining whether a signal from a TCU is a shift signal or not, converting a throttle opening versus vehicle speed shift line into a engine torque versus vehicle speed shift line, and if the signal from the TCU is a shift signal, determining if a present acceleration pedal displacement value relative to the engine torque is less than a predetermined value, and synchronizing the engine torque to a predetermined value if the acceleration pedal displacement value indicates the engine torque is less than the predetermined value.
