Title:
HYBRID VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2018086974
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To detect abnormality of a power transmission state of an automatic transmission, and to prevent sudden generation of large drive force associated with sudden engagement of a hydraulic pressure type engagement device to generate shock when engine is started-up and a mechanical oil pump is operated.SOLUTION: A linear solenoid valve SL1 is controlled so that engagement of a clutch C1 is released when blowing occurs at the time of start in a motor travel mode and an engine is started up in S4 (S3); the linear solenoid valve SL1 is controlled so that the clutch C1 is re-engaged, after start-up of the engine, in other words, after start-up of a hydraulic pressure of a mechanical oil pump (S5); and accordingly sudden engagement of the clutch C1 associated with supply of hydraulic oil from the mechanical oil pump can be prevented, and shock caused by fluctuation of drive force at the time of engagement of the clutch C1 can be prevented.SELECTED DRAWING: Figure 6
