    摘要: A hydraulic control device for an automatic transmission that can ensure power transmission when a failure occurs to the solenoid valve of the hydraulic control device, the hydraulic control device having a plurality of hydraulic servos for engaging and disengaging a plurality of friction engagement elements in accordance with the supply and discharge of a hydraulic pressure so as to prevent interlock from occurring to the transmission, a solenoid valve for generating a predetermined hydraulic pressure and supplying the predetermined hydraulic pressure to a hydraulic servo selected in correspondence with a target gear ratio and fail-safe means for supplying fail-safe hydraulic pressure to at least two hydraulic servos selected to attain an arbitrary gear ratio when a failure occurs to the solenoid valve and power transmission thereby becomes impossible. Further, the hydraulic control device has a plurality of solenoid valves for supplying the predetermined hydraulic pressure to the plurality of hydraulic servos and a shutoff valve, disposed between a hydraulic pressure source and one of the solenoid valves, for shutting off supply of hydraulic pressure to that one solenoid valve when hydraulic pressure to be supplied to the hydraulic servos selected in correspondence with the target gear ratio and hydraulic pressure to be supplied to the other hydraulic servos are generated.

    摘要: A vehicle including an internal combustion engine and a stepped transmission including an input shaft and an output shaft, wherein the stepped transmission speed-changes power input to the input shaft while changing a shift speed and outputs the speed-changed power to the stepped transmission output shaft; a control unit that controls the engine and the stepped transmission in accordance with an output request from an operator. The vehicle also including input and output shaft rotation speed detecting units and an output limiting unit that limits the output of the engine by comparing the deviation of the input and output shaft rotation speed to a predetermined rotation speed relationship range. The vehicle also including an abnormality determining unit to determine that an abnormality has occurred in the stepped transmission when the rotation speed relationship exceeds the range of the predetermined rotation speed relationship for at least a first predetermined time period.
