Title:
CONTROLLER FOR VEHICULAR DRIVE UNIT
Document Type and Number:
Japanese Patent JP2008162537
Kind Code:
A
Abstract:

To provide a controller for vehicular drive unit capable of restraining the first electric motor from becoming a high rotational speed state, even when a rotational direction of a driving shaft is brought into a rotational direction opposite to the rotating direction in a travel position.

Rotation is restrained from being driven along a direction that is opposite to the rotation in the travel position set with a transmission member 18, because a reverse driving force input, from an output side of an automatic transmission part 20, such as an output shaft 22 and driving wheels into a differential part 11, is restrained by an opposite driving force restraining means 86, when the driving wheels are brought into the rotational direction reverse to the rotational direction in the travel position selected by a shift operation device 50, and the first electric motor rotation speed NM1 determined by an engine speed NE and a transmission member rotation speed N18 is thereby restrained from becoming the high rotation speed, based on a relation between mutual relative rotation speeds in the differential part 11. As a result, durability of the first electric motor M1 is improved.
