PURPOSE:To properly judge the variation time point of the load acting on an engine independently of the temperature of the working oil when range is selected between the traveling range and the nontraveling range. CONSTITUTION:A sensor 32 for detecting the input number of revolution of a shift mechanism 13 and a sensor 33 for detecting the temperature of working oil are provided, and a control unit 30 which judges the change time point of the load acting on an engine 20 on the basis of the lapse of time from the range selection time point when the temperature of the working oil is high, while on the basis of the variation of the input number of revolution of the shift mechanism 13 when the temperature of the working oil is low is provided. |
