<P>PROBLEM TO BE SOLVED: To provide a running control structure capable of effectively preventing a multi-speed transmission device from coming into a power interruption state although a multi-speed gear shift actuator performs operation corresponding to the operation from one side to the other side of high speed stage position or low speed stage position of a multi-speed shift operating member. <P>SOLUTION: A control device 800 performs operation control of an auxiliary gear shift actuator 81 so that an auxiliary transmission device 200 performs the corresponding shift operation based on a signal from an auxiliary gear shift detection sensor 890 corresponding to the operation from one side to the other side of the high speed stage position or the low speed stage position of the auxiliary shift operating member 840. Afterwards, the control device 800 determines whether shift operation of the auxiliary transmission device 200 is successfully done or not based on the signal from an auxiliary gear shift detection sensor 850. When the auxiliary transmission device 200 fails to shift to the other speed gear, the operation control of the auxiliary gear shift actuator 81 is performed so that the auxiliary transmission device 200 is returned to the speed gear before the operation of the auxiliary shift operating member 840. <P>COPYRIGHT: (C)2009,JPO&INPIT |
