PURPOSE:To suitably perform speed change control and reverse impeding control by selecting a forward position operational signal, when forward/reverse position operational signals are simultaneously generated, in a condition that a wrong output of the forward position operational signal is not detected, and actuating a reverse impeding device based on a selected reverse position operational signal in a condition that the wrong output is detected. CONSTITUTION:In a signal selecting means, in a condition that a forward position operational signal is not detected wrong output from a forward position operational signal wrong output detecting means, when forward and reverse position operation signals are simultaneously generated, the forward position operational signal is selected. On the other hand, in a condition that the forward position operational signal is detected wrong output, when the forward/reverse position operational signals are simultaneously generated, the reverse position operational signal is selected. Speed change ratio is controlled by a speed change control means while actuating a reverse impeding device by a reverse impeding device control means based on the selected signal by a signal selecting means. |
