<p>PURPOSE:To detect the torque of a wide range with a simple structure by determining the torque transmitted on the basis of an input current when the input current is controlled to make the rotating speed between output shafts equal. CONSTITUTION:A control device 40 reads a vehicle speed from a vehicle speed detecting sensor 57, connects a motor 54 to a gear 52 with an electromagnetic clutch 53 when the vehicle speed is lower than a fixed value, and reads the rotating speeds thetaa, thetab of output shafts 13, 14 from sensors 28, 29. When the speeds thetaa, thetab are not equal to each other, the input current of a torque generating device 15 is changed by a preset unit quantity so that they are equal to each other, and this is repeated until they become equal to each other. When they are equal to each other, the torque transmitted from an input shaft 12 to the output shaft 14 is calculated. This torque and the motor driving current according to the read vehicle speed are operated, and the current to be carried from the motor driving circuit 55 to the motor 54 is controlled according to the calculated value. The deviation from a motor driving current calculated by reading the actual motor driving current from a current detecting circuit 56 is determined, and the control of the current to be sent to the motor 54 is repeated until the deviation, if present, is eliminated.</p> |
