A lubricating oil relief valve 6 is connected to the lubricating oil supply path. The relief valve 6 is urged to the right closing side by a spring 6a, and is pressed to the left opening side by the hydraulic pressure input to the right end oil chamber 6b. Thus, if the oil pressure in the oil chamber 6b is increased, the amount of leakage from the relief valve 6 increases, the amount of lubricating oil supplied to the lubrication point decreases, and if the oil pressure in the oil chamber 6b is reduced, The amount of leak from the relief valve 6 decreases, and the amount of lubricating oil supplied to the lubrication point increases. An electromagnetic valve 7 controlled by the controller 5 is provided in a hydraulic input oil passage for the oil chamber 6b, and when the electromagnetic valve 7 is opened to increase the oil pressure in the oil chamber 6b, the oil amount of the lubricating oil is reduced to a normal value. When the solenoid valve 7 is closed, the oil pressure in the oil chamber 6b is reduced and the amount of lubricating oil is increased from a normal value.

潤滑不足が回避される。The details of the control of the solenoid valve 7 by the controller 5 are as shown in FIG. 2. First, it is determined whether or not the vehicle speed is zero in step S1, and if the vehicle speed is zero, that is, if the vehicle is stopped, In step S2, the solenoid valve 7 is opened to set the lubricating oil amount to a normal value. If the vehicle is traveling, it is determined in step S3 whether or not the currently traveling road surface gradient Rθ is an upward gradient that is equal to or greater than a predetermined value YRθ. The road surface gradient Rθ
Calculates the wheel driving force from the engine torque obtained from the engine rotation speed and the intake negative pressure and the transmission ratio,
It can be obtained from the correlation between the wheel driving force and the vehicle acceleration. Further, the road surface gradient Rθ can be detected by a sensor such as an inclinometer. If Rθ <YRθ, S
In step 2, the solenoid valve 7 is opened.
If Rθ, the solenoid valve 7 is closed in step S4,
Increase the amount of lubricating oil from the normal value. Thus, even when the load on each part of the transmission increases when climbing a hill, insufficient lubrication can be avoided by increasing the amount of lubricating oil.
