Title:
DRIVE TRANSMISSION DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2017067161
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a drive transmission device for vehicle capable of improving accuracy of hydraulic control by preventing a detection value of an oil temperature from being deviated by heat occurring from a solenoid device.SOLUTION: A first solenoid valve arranged in a valve body of an automatic transmission is energized in an engine stop state. A control unit (TCU) starts energization to the first solenoid valve in the engine stop state, interrupts energization in a case where a predetermined time elapses from start of energization, and then resumes energization when a predetermined restoration condition is established. Consequently, heat generated from the first solenoid valve is prevented from being propagated to an oil temperature sensor arranged in the valve body, and thereby the oil temperature can detect an oil temperature with high accuracy.SELECTED DRAWING: Figure 3
