Title:
CLUTCH CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/111457
Kind Code:
A1
Abstract:
Sleeves (22, 32H, 32L) and engagement gears (16d, 11d, 15d) are provided to positive clutches (20, 30H, 30L) positioned between first shafts (11, 13), to which power is transmitted by rotating in synch with rotating electric machines (3, 4), and second shafts (15, 16), to which the power from the first shafts (11, 13) is transmitted. A control device (5) comprises: a rotation control unit (5A) which, while a vehicle is travelling with the clutches (20, 30H, 30L) disengaged, controls the rotating electric machines (3, 4) so as to match the rotation of the sleeves with the rotation of the engagement gears; a sleeve control unit (5B) which, during the control performed by the rotation control unit (5A), moves the sleeves in a first direction to engage the sleeves with the engagement gears; movement detection units (45a-45c) which detect the movement amount D of the sleeves; and a determination unit (5C) which, if the movement amount D is below a pre-set prescribed amount Dp, determines that gear blocking, wherein the sleeves and the engagement gears collide without meshing together, has occurred.
