PURPOSE:To control a variation of a gain of the whole of a constant running system, by correcting a varying vehicle gain by detecting a running state of a vehicle such as high and low load running by a pressure switch detecting suction manifold pressure. CONSTITUTION:In case of running on a flat road at a common speed region, pressure switches 104, 108 are turned OFF and, for example, when a speed-up signal 1a is given from a controll circuit 1, the signal 1a is applied to a D.C. motor 2, a resistor 103, a diode 106 and the control circuit 1 in order of the foregoing and a sector 5 is revolved by a revolution of the D.C. motor 2 through a speed reduction mechanism 3, through which a speed-up operation of a throttle valve 8 is performed. On the other hand, at the time of high (low) load running on an acclivity (declivity) the pressure switch 104 (108) is turned ON through a decrease (increase) of suction negative pressure. With this construction, an acceleration side gain of a vehicle is corrected by applying the speed-up signal 1a to the D.C. motor 2, the high opening switch 104, the diode 106 and the control circuit 1 in order of the foregoing at the time of the high load running. |
