Abstract: PROBLEM TO BE SOLVED: To improve the durability of an automatic transmission by controlling an excessive inertia torque working on the automatic transmission on sudden braking. SOLUTION: If a driver operates a brake pedal (YES at S106) while an actual vehicle speed is lower than a threshold value (YES at S100) and driving wheels are idling on a low-μ road (YES at S102, S104), an ECU controlling a belt-type continuously variable transmission executes upshift control for decreasing a transmission ratio by a predetermined value (S108), and also executes clamping-force increasing control for increasing a belt clamping pressure by a predetermined value (S110).

Abstract: PROBLEM TO BE SOLVED: To improve a mileage while ensuring driving force on an uphill road at the start of a vehicle.SOLUTION: Since a target gear ratio (target input rotation speed Nint) at the stop of the vehicle is set to a larger ratio as a road gradient becomes larger, speed change timing (L/U-off vehicle speed Vs0, Vs1) can be delayed when the road gradient is small such as on a flat road or a gradual uphill road. Thus, a range in which a gear ratio can be maintained at a Hi side can be widened and the mileage can be improved. In addition, when the road gradient is large, such as a steep uphill road, the driving force at the start of the vehicle can be ensured by setting the gear ratio at the stop of the vehicle to a maximum gear ratio γmax and therefore the mileage can be improved while ensuring the driving force on the uphill road at the start of the vehicle.

Abstract translation: 要解决的问题：在车辆启动时确保上坡道路上的驱动力的同时提高里程。 解决方案：由于随着道路坡度变大，车辆停止时的目标齿轮比（目标输入转速Nint）被设定为较大的比例，因此，变速时刻（L / U关车速度Vs0，Vs1 ）可以在道路坡度小的情况下延迟，例如在平坦的道路上或逐渐上坡的道路上。 因此，能够使在Hi侧保持齿轮比的范围变宽，能够提高里程。 此外，当道路坡度大的情况下，例如陡峭的上坡道路时，通过将车辆停止时的齿轮比设定为最大变速比γmax，可以确保车辆起动时的驱动力， 可以在确保车辆起点处的上坡道路上的驱动力的同时进行改进。 版权所有（C）2012，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a device for controlling a lubricating oil passage of a belt type continuously variable transmission for a vehicle capable of achieving effective lubrication. SOLUTION: This device for controlling the lubricating oil passage supplies lubricating oil discharged from a drain oil passage to an input side variable pulley 42 and/or an output side variable pulley 46 not through an oil cooler 124 when lubricating temperature is equal to or lower than previously fixed specified temperature. Consequently, efficient lubrication is achieved at the time of low oil temperature in starting a vehicle, etc. by supplying the lubricating oil of comparatively high temperature discharged from the drain oil passage not through the oil cooler 124 for lubrication of pulley bearing parts 134, 136 especially easy to cause loss when lubricating oil temperature is comparatively low.

Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic control device for a vehicular power transmission device capable of increasing the flow amount of operating oil flowing from a relief type pressure regulating valve to the upstream side of an oil pump. SOLUTION: A first orifice 128 is formed on the upstream side of a first oil passage 122 beyond a cooler 124, and a second orifice 130 is formed in a second oil passage 118. The orifices 128, 130 regulate the flow amount of operating oil flowing in the oil passages 122, 118 to suppress an excessive flow amount. The second oil passage 118 is connected at its downstream side between the first orifice 128 in the first oil passage 122 and the cooler 124, and a lubricating pathway 132 is connected to the downstream side beyond the cooler 124. Therefore, the lubricating pathway is formed in one line and the cooler 124 is connected in series to the lubricating pathway 132 to make the flow amount in the cooler same as a lubricating flow amount. This increases the flow amount of the operating oil flowing from a secondary regulator valve 112 to the upstream side of the oil pump 28. COPYRIGHT: (C)2008,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a control device of a continuously variable transmission which can surely prevent slippage with respect to pulleys of a transmission belt when the transmission belt is in an easily slidable state, and can reduce a friction loss and a pump load within a range that the transmission belt does not slide when the transmission belt is not in the easily slidable state, and a control program. SOLUTION: When the secondary pulley is stopped (YES in a step S12), the hydraulic pressure of the secondary pulley is increased (step S15) when it is detected that torque inputted into the primary pulley is decreased (YES in a step 14). Then, when it is detected that the secondary pulley is not in a stopped state (NO in steps S12, S17), the hydraulic pressure is changed to that of the secondary pulley (step S18).
