VEHICLE ENGINE CONTROL SYSTEM.

摘要

When a step-on detection signal is outputted from the accelerator pedal operation state (81), a first controlled variable setting unit (82) sets the controlled variable of engine output regulator (7) in accordance with a manipulated variable detection signal. When a step-on release detection signal is outputted from the accelerator pedal operation state detector (81), a second controlled variable setting unit (86) receives the output of a constant speed driving speed designation signal from driving state designation device (83) and sets the controlled variable of the engine output regulator necessary for making the driving speed of a vehicle equal to a target speed on the basis of the driving speed detection signal from driving speed detector. When an acceleration driving designation signal is outputted from the driving state designation device, the second controlled variable setting unit sets the controlled variable of the engine output regulator necessary for the vehicle to accelerate. Because the second controlled variable setting unit (86) sets a controlled variable which serves to vary vehicle in accordance with the time and the vehicle speed, the speed change of the vehicle can be made smoothly through the engine output regulator (7) operating on the basis of this controlled variable.
