Abstract
A control system for a drive unit of a vehicle, in which a power distribution mechanism is arranged on a route from a prime mover to a wheel, and a transmission is arranged on an output side of the power distribution mechanism. The control system includes a revolution frequency controller that restrains a variation in a revolution frequency of the prime mover by controlling a revolution frequency of the reaction force establishing device until a predetermined time elapses since a commencement of a shifting operation of the transmission. The control system is capable of restraining a variation in an output torque, in case of carrying out a shifting operation of a transmission arranged on an output side of a prime mover.
