Abstract

PURPOSE: To prevent the drop of driving force and the deterioration of the specific consumption of fuel, by constituting a speed control mechanism so as to set a lower gear change speed as an engine wears.
CONSTITUTION: When the integral number of revolutions of an engine 7, the integral used time of the engine or the integral covered distance of a car is large, the gear change speed is set low. The wear of the engine 7 also increases in proportion to the increases of the integral number of revolutions of the engine 7, the integral used time of the engine or the integral covered distance of the car. On the contrary, when the integral number of revolutions of the engine 7, the integral used time of the engine of the integral covered distance of the car is small, the gear change speed is set high. That is, an electronic controller 40 calculates the fuel injection quantity by means of an input signal from each sensor acting as a parameter and sends an electric pulse of the width corresponding to the calculated fuel injection quantity to an injection valve 41. The electronic controller 40 further controls a bypass flow control valve 22, an EGR control valve 24, a solenoid valve 44 of an oil pressure control circuit of an automatic speed change gear and an ignition coil 45.
