Abstract:
1. A control system for a drive unit of a vehicle, in which a prime mover is arranged on a power transmission route from a continuously variable transmission to a wheel, in which a clutch mechanism is arranged on a route from the prime mover to the wheel, and in which a shift range or shift position of a shifting device can be shifted selectively between a drive range or drive position where a motive power can be transmitted through the route from the prime mover to the wheel and a non-drive range or non-drive position where a motive power cannot be transmitted through the route from the prime mover to the wheel, comprising: a vehicle speed control demand judging means for judging a vehicle speed control demand in case of shifting the shift range or shift position of the shifting device from the non-drive range or non-drive position to the drive range or drive position; and a prime mover control means for controlling a torque of the prime mover on the basis of a judgment of the vehicle speed control demand judging means, wherein the vehicle speed control demand judging means includes a means for judging a braking demand, the prime mover control means includes a means for increasing a torque of the prime mover, and a means for changing a timing of increasing the torque of the prime mover depending on an existence of the braking demand, and the prime mover control means includes a means for accelerating the timing of increasing the torque of the prime mover in case the braking demand is not being outputted, in comparison with the timing of the case in which the braking demand is being outputted.
