Document Type and Number:
Japanese Patent JP5018871
Kind Code:
B2
Abstract:
To provide a control device for a driving device of vehicle, for suppressing excessive rotation of the rotating member or second motor of the input system of a mechanical transmission part, or the like, even if the transmission torque capacity of an engagement device is deteriorated due to any failure while a vehicle is traveling.
Since the output torque of an engine 8 becomes restricted, according to a rotating speed difference ΔNINbetween the actual rotating speed NIN1 of the input member of an automatic transmission part 20 and an actual vehicle speed V(rotating speed NOUTof an output shaft 22) and a theoretical input member rotating speed NIN2(=γ×NOUT) calculated based on a shift ratio γ of the automatic transmission 20; and even if the transmission torque capacity of an input clutch C1 and/or C2 is deteriorated due to any failure, while the vehicle is traveling, the excessive rotation of a rotating member at an engine 8 side of the input clutch C1 and/or C2 and a bearing rotating relevantly with this and a second motor or the like is suppressed in the input system of the automatic transmission 20, it is possible to secure durability of the rotating member and the bearing which rotating, in relation to this and the second motor, or the like.
