Title:
HYDRAULIC CIRCUIT DEVICE AND LINE PRESSURE RAISING METHOD OF HYDRAULIC CIRCUIT
Document Type and Number:
Japanese Patent JP2018168907
Kind Code:
A
Abstract:
To provide a hydraulic circuit device and a line pressure raising method of a hydraulic circuit which can supply oil pressure to the maximum after recovery from idling stop by raising a line pressure to completely accumulate the pressure in an accumulator before execution of idling stop, and which can avoid deterioration of fuel economy due to pressure rising of the line pressure higher than required for preparation of idling stop when idling stop is not performed.SOLUTION: A hydraulic circuit device includes a transmission condition determination step, a system condition determination step, and a first specified vehicle speed condition determination step. Pressure rising of a line pressure is performed to accumulate the pressure in an accumulator when the condition is satisfied in the transmission condition determination step, the condition is satisfied in the system condition determination step, and the condition is satisfied in the first specified vehicle speed condition determination step.SELECTED DRAWING: Figure 2
