<P>PROBLEM TO BE SOLVED: To contribute to reduction in manufacturing cost of a traveling vehicle, by dispensing with an expensive control means superior in operation capacity, by surely performing releasing processing from an actuator abnormality determining state even by a control means of a low hardware specification, in the traveling vehicle having the return function of an actuator for operating a clutch of a reverser. <P>SOLUTION: A checking signal is sent out toward the actuator, only when a reverser lever is displaceably operated to a neutral range from an advance or retreat range by an operator. The release processing of an abnormality determining state is performed by comparing a signal valve of a feedback signal from the actuator with a threshold value. Thus, since processing capacity required for the control means can be reduced more than the return function of a conventional form for capturing a change with the lapse of time of the signal value, there is no need to adopt the expensive control means superior in the operation capacity, to thereby contribute to reduction in the manufacturing cost of the traveling vehicle. <P>COPYRIGHT: (C)2007,JPO&INPIT |
