Zusammenfassung:	PURPOSE: To make smooth shift possible by deciding transmission relative speed as a function of transmission output speed and transmission input speed, and controlling to engage and disengage an input clutch according to it. CONSTITUTION: An electronic hydraulic control device 76 for operating a drive train including an engine and a transmission of a vehicle 12 such as a grading wheel loader, is provided with a first actuator mechanism 80 for controlling the transmission. This mechanism 80 comprise a vertical control rod 82 provided with a speed selector device 84 for shift operation and a directional selector device 88 for changeover of forward/backward, and electric signals corresponding to the operation of the respective selector devices 84, 88 are output to an electronic control module 78. This electronic control module 78 inputs the input/ output speed signals of the transmission, and decides clutch relative speed as the function of input - output speed to control to engage or disengage the input clutch.
