PROBLEM TO BE SOLVED: To reduce a torque shock which can be generated in the output shaft and the driving shaft of a prime mover by smoothly changing over a motor to the output shaft and the driving shaft of the prime mover, in a motive-force output device which can be attached so as to change over the motor to the output shaft and the driving shaft of the prime mover. SOLUTION: On the basis of the present engine revolutions Ne and the past engine revolutions Nd and on the basis of the present revolutions of driving-shaft Nd and the past revolutions of driving-shaft Nd, the engine revolutions Nen and the revolutions of driving-shaft Ndn after the time corresponding to a control delay has elapsed are estimated (S104, S106), and a changeover point in an operating mode is judged on the basis of their estimated values (S108). Since the changeover point is judged by using the estimated values, the deviation of the changeover point due to the control delay can be reduced. As a result, an output shaft and a driving shaft can be changed over smoothly, and a torque shock which can be generated in the driving shaft can be reduced. |
