A branching device for a transmission line, including a main transmission line including at least two signal lines and having respective connectors provided at either end; a first branch transmission line which branches from the signal lines and which has a branch-use connector at an end; a second branch transmission line which branches from the signal lines and which has a branch-use terminal block at an end; a terminating resistor having one end connected to one of the signal lines; and a selection switch that switches the other end of the terminating resistor between connecting with an other one of the signal lines, and forming an open circuit.

During an upshift in a full-throttle state, the output of a shift command (Us ) from a control unit is followed by a delay in initiation of an actual shift, due to a delay in increase in oil pressure, a rise in the clutch torque load, etc. A shift initiation (Uj) is determined by comparing the input rotational speed (Ni) with the product of multiplication of the output rotational speed (vehicle speed) (No) by the pre-shift gear ratio. The shift point (Mp ) is learning-corrected based on the shift initiation-time engine rotational speed (NeI). Therefore, false learning is avoided even if the engine races during a shift.
