Abstract
A control system for a vehicle engine comprises a first detector for detecting a controlled variable on an accelerator, a setting device for determining a fundamental control variable on an engine output adjusting device, such as a throttle valve, based on an output of the first detector, a driving device for actuating the engine output adjusting device in accordance with the fundamental control variable, a second detector for detecting a demand for acceleration of a vehicle, a compensating device for revising the fundamental control variable to produce a compensated control variable on the engine output adjusting device so that the engine output adjusting device is actuated in accordance with the compensated control variable when the demand for acceleration of the vehicle is detected by the second detector, a restoring device for restoring the engine output adjusting device at a predetermined restoration speed to be actuated in accordance with the fundamental control variable after the engine output adjusting device is actuated in accordance with the compensated control variable, a third detector for detecting a travelling condition of the vehicle, and a restoration speed setting device for varying the predetermined restoration speed in response to the travelling condition of the vehicle detected by the third detector.
