PURPOSE:To facilitate engine control test, by providing a mode switching means which can stop speed change control and carry out engine control, and switching the mode when specific external operating conditions are satisfied. CONSTITUTION:A gear change control circuit 13 is connected through switching circuits 14, 15, 16 to a clutch drive 6, a speed changer drive 7 and a switching circuit 17 one contact (a) of which is connected to an engine control circuit 18 while the other contact (b) is connected to an engine control circuit 19 during gear change and the output section thereof is connected to a fuel controller 5. Consequently, even when the speed change control is related to engine control, the engine control test can be carried out easily without the influence of speed change control. |
