Title:
CONTROL DEVICE OF HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2015143050
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress fastening shock of a clutch and prolongation of a fastening time even when a rotation speed difference between the input and output of the clutch is great when switching from an EV mode to a HEV mode.SOLUTION: When switching from an EV mode to a HEV mode, control means restarts an engine 1 and determines whether or not an absolute value of a subtraction value between rotation speeds of the input and output of a clutch CL is greater than a predetermined rotation speed difference. If the absolute value of the subtraction value is determined to be greater than the predetermined rotation speed difference, the control means performs synchronization control of the rotation speed of the engine 1 and a transmission ratio of a non-stage transmission in accordance with the subtraction value so that the rotation speeds of the input and output of the clutch CL are synchronized. Once Synchronized, the control means fastens the clutch CL. If the absolute value of the subtraction value is within the predetermined rotation speed difference, the control means fastens the clutch after a predetermined time from a command of switching without performing the synchronization control in accordance with the subtraction value.
