Abstract

In a motor control method and apparatus for an internal combustion engine, a point for the beginning of injection moment and injection period for each cylinder are determined in a load-controlled way in a motor controller and supplied to the actuators for execution of the injection. To improve the response characteristic of the internal combustion engine, control information for injection of the cylinder currently to be addressed is transmitted as reserve information for the subsequent cylinder in every transmission cycle. In the event of a load increase, reserve information from the previous transmission cycle is used to control injection in the subsequent cylinder.
