Title:
VEHICLE CONTROL UNIT
Document Type and Number:
Japanese Patent JP2015232390
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress the occurrence of up-lock to an engagement clutch even if a vehicle is stopped.SOLUTION: In a case of actuating a synchronization mechanism S1, an engine revolving speed Ne is set relatively high and a rotation speed (turbine rotation speed Nt) of a rotation member of a friction clutch (that is, a brake B1 for reverse drive and a clutch C1 for forward drive) near an engine 12 is set relatively high. Owing to this, a drag torque of the friction clutch facilitates rotating a rotation member of the friction clutch near an engagement clutch D1. If the rotation member of the friction clutch near the engagement clutch D1 rotates, a predetermined rotation member of the engagement clutch D1 (synchronization mechanism S1) near the friction clutch can be rotated. It is, therefore, possible to suppress the occurrence of up-lock of the engagement clutch D1 even if a vehicle is stopped.
