PURPOSE:To detect the start of torque phase automatically in an accurate manner by installing a torque phase start detecting means which sets a moment when a differential value has came to a negative third setting value larger than the minimum value finally during the while up to a first moment, to a torque phase start. CONSTITUTION:A differential operating means finds the differential value of transmission output torque detected by an output torque detecting means. A minimal differential value detecting means finds the minimum value of the differential value at time of up to a second moment when the differential value has come to a second setting value larger than the first setting value, before the first moment when this differential value becomes less than the first setting value. A torque phase start detecting means sets a torque phase start with a time when the said differential value comes down to one half or one third or so of the said minimum value finally during the while of up to the first moment, detecting it. Accordingly, this torque phase start is made accurately and automatically detectable without resting on man power each. |
