ABSTRACT:
An engine control system for suppressing vibration of a car body, primarily at acceleration thereof, by varying engine output torque. The system for suppression of the car body vibration takes into consideration car vibration detection delay time created by the intermittent detection of vibration data. The system includes a detector for intermittently detecting data relating to car body vibration, a period setting device for setting a period of car body vibration, a delay time setting device for setting a delay time corresponding to a detection delay time due to the intermittent detection of the vibration data detector, and a torque controller for controlling engine output torque by advancing a phase of engine output torque control timing by the delay time corresponding to the detection delay time, which is set by the delay time setting device, in each period of car body vibration set by the period setting device.
