摘要： A controller for a vehicle continuously variable transmission is disclosed. When a target gear ratio is set as the maximum gear ratio and a vehicle speed is decreased to less than a first reference vehicle speed, the controller suspends varying of the gear ratio by the transmission control and starts a gear ratio hold control that releases operational oil from a first oil pressure chamber and holds the gear ratio at the maximum gear ratio. Further, the controller ends the gear ratio hold control and delivers operational oil to the first oil pressure chamber when the vehicle speed increases to a second reference vehicle speed or greater, which is lower than the first reference vehicle speed, and restarts the varying of the gear ratio by the transmission control when the vehicle speed subsequently increases to the first reference speed or greater.

摘要： In a controller for a belt-type continuously variable transmission including a hydraulic actuator that changes a groove width of a primary pulley, a hydraulic actuator that changes a groove width of a secondary pulley, and a belt clamping pressure control solenoid that controls the hydraulic pressure supplied to the hydraulic actuator of the secondary pulley, a mechanism calculates a transmission ratio between the primary pulley and the secondary pulley and determines whether or not there is belt slippage based on that calculated transmission ratio, and a mechanism determines normalcy of the belt clamping pressure control solenoid. The input torque when belt slippage has actually occurred, i.e., when a failure has been determined, is used as a condition when performing the normalcy determination. By setting such a condition, it is possible for a normalcy determination threshold value (input torque value α) used for the normalcy determination to be a small value, and thus it is possible to suppress erroneous normalcy determination.

摘要： In an embodiment of the continuously variable transmission control apparatus of the present invention, even if an actual gear change ratio RATIO overshoots a target gear change ratio RATIO T and an upshift gear change instruction (DS1 gear change duty output) is switched to a downshift gear change instruction (DS2 gear change duty output) during gear change due to the upshift gear change instruction, in the case where the upshift gear change speed is fast, specifically, in the case where a maximum actual sheave position change ratio DWDRmax is not less than a determination threshold g, it is determined that the transmission is capable of performing an upshift gear change, and the upshift gear change state is determined to be normal. In this manner, a normalcy determination is performed more frequently.

摘要： A diagnostic apparatus and a diagnostic method are provided for a belt squeezing force adjusting mechanism of a continuously variable transmission in which a belt is wound around a primary sheave that receives driving force and a secondary sheave that outputs force to a drive line, and which continuously changes the output rotation speed by adjusting the width of the groove the primary sheave and the secondary sheave by shift control. This diagnostic determines, as a precondition, whether a target control value calculated in shift control is in a low region, and performs a diagnostic on the belt squeezing force adjusting mechanism based on the relationship between an actual control value and the target control value during control to reduce a control value when it is determined that the precondition is satisfied. According to this diagnostic apparatus and diagnostic method, an erroneous diagnosis can be prevented so the diagnostic can be performed accurately.
