    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: Disclosed is an electronic controller which calculates the variable amounts of the thrust in a primary pulley based on the thrusts of the pulleys, the lower limit thrust and the upper limit thrust in the steps of a target change gear ratio limit routine. The electronic controller calculates the limit transmission speeds based on the variable amounts in the steps, and calculates the guard values for limiting the target change gear ratio based on the limit transmission speeds in the steps. An electronic controller limits the target change gear ratio by the guard values thus calculated, and controls the thrusts of the pulleys by feedback control based on the size of discrepancy of the limited target change gear ratio and the current change gear ratio γ.
