Controller of vehicle driving device

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;
• a transmission is arranged on an output side of the power distribution mechanism;
• the power distribution mechanism comprises an input element connected with the prime mover, a reaction element connected with a reaction force establishing device and an output element connected with an input side of the transmission;
• and a speed change ratio of the power distribution mechanism is controlled by controlling an output of the reaction force establishing device establishing a reaction force against the prime mover, wherein:
• a control content for controlling a revolution frequency of the reaction force establishing device is changed in case of carrying out a shifting operation of the transmission, from the control content for controlling a revolution frequency of the reaction force establishing device of a case in which a shifting operation of the transmission is not carried out.

• the power distribution mechanism comprises an input element connected with the prime mover, a reaction element connected with a reaction force establishing device and an output element connected with an input side of the transmission;
• and a speed change ratio of the power distribution mechanism is controlled by controlling an output of the reaction force establishing device establishing a reaction force against the prime mover, wherein:
• a variation in a revolution frequency of the reaction force establishing device resulting from an execution of a revolution control in case of carrying out a shifting operation of the transmission is restrained smaller than that of a case in which the shifting operation of the transmission is not carried out.

A control method for a drive unit of a vehicle, in which:

• a transmission is arranged on an output side of the power distribution mechanism;
• the power distribution mechanism comprises an input element connected with the prime mover, a reaction element connected with a reaction force establishing device and an output element connected with an input side of the transmission;
• and a speed change ratio of the power distribution mechanism is controlled by controlling an output of the reaction force establishing device establishing a reaction force against the prime mover, comprising:
• a revolution frequency control restraining a variation in a revolution frequency of the prime mover by controlling a revolution frequency of the reaction force establishing device within a predetermined time from a commencement of a shifting operation of the transmission.
