Title:
CONTROL DEVICE OF COAST STOP VEHICLE
Document Type and Number:
Japanese Patent JP2015010710
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a coast stop vehicle having a clutch to be brought into a coupling state by the hydraulic pressure of a mechanical oil pump and an electrically-driven oil pump, in which a torque shock of the vehicle after the start of a coast stop is suppressed.SOLUTION: A coast stop vehicle comprises: a clutch 33 which is interposed between an engine 1 and drive wheels, and can connect and disconnect power; a hydraulic pressure source having a mechanical oil pump and an electrically-driven oil pump for driving the engine; clutch pressure control means 12g which controls the hydraulic pressure of a hydraulic oil to be supplied to the clutch 33 from the hydraulic pressure source on the basis of command pressure; and inversion determination means 12f which determines the inversion of the engine 1. When the inversion of the engine 1 during a coast stop is detected, the clutch pressure control means 12g lowers the command pressure to low command pressure lower than coupling hydraulic pressure until the inversion ends, then raises the low command pressure to a filling command pressure higher than the coupling hydraulic pressure for a filling time, and lowers the filling command pressure to standby command pressure lower than the coupling hydraulic pressure and higher than the low command pressure, and fills the hydraulic oil to an oil chamber on the basis of the filling command pressure and the standby command pressure.
