Abstract
The engine control system of the present invention comprises an engine output changing device for controlling an engine output of at least one of engine power, engine, engine torque and engine speed. At least two controls for controlling the engine output changing device are selected from a direct control device for directing detecting an actual value to which the engine output changing device is operated. A target value for the engine output changing device is set based on an amount an accelerator is operated to thereby adjust the engine output changing device to eliminate a difference between the actual value and the target value. A vehicle speed control device for detecting an actual vehicle speed, setting a target value of vehicle speed based on the amount the accelerator is operated, and for controlling the engine output changing device, and an acceleration control device for detecting a change in an actual vehicle speed, setting a target value of vehicle acceleration based on the amount the accelerator is operated, and for controlling the engine output changing device, are also provided. A selecting device is used to select one of the direct control, vehicle speed control and…
