Abstract
An engine control apparatus which performs torque-down control during shifting is structured so as to determine a retard rate from an MBT ignition timing which will achieve a target torque-down rate, and determine a target ignition timing based on that retard rate. The retard rate that achieves a given torque-down rate changes substantially linearly with respect to the MBT ignition timing, so that change is easy to predict. Accordingly, the structure and configuring and the like of the engine control apparatus are simplified.
