摘要： In a case of an electric failure caused to a traveling vehicle and when any of forward gears is held at a step S5, a comparison is made between: 1) a supposedly-engaged friction element of friction elements which is supposed to be engaged at the any of the forward gears and 2) an actually-engaged friction element of the friction elements which is sensed to be actually engaged, the sensing being based on a switch signal from a first hydraulic pressure switch 11, a second hydraulic pressure switch 12, a third hydraulic pressure switch 13, a fourth hydraulic pressure switch 14 and a fifth hydraulic pressure switch 15. When the supposedly-engaged friction element is not in accordance with the actually-engaged friction element, an electric system is determined to be in failure. In the case of the electric failure, a routine moves to a step S6 and subsequent steps for sticking the gear of an automatic transmission to a given gear. As described above, a shift control system of the automatic transmission is thus provided that can eliminate a sleeping failure thereby securely preventing an interlock and that can secure a high shift controllability which is not, in a period of shift, restricted in terms of hydraulic pressure control range of each of the friction elements.

摘要： A method and apparatus for operating an automatic transmission as a function of the engine rotational speed of a variable speed internal combustion engine. Upon a failure of the electronic control system, a return home of a motor vehicle under its own power is enabled. A delivery system delivers a working medium with which a transmission ratio adjusting device is actuated by a first control device that, in turn, is controlled by a pilot pressure that can be accurately changed by a second control device to actuate the transmission ratio adjusting device. The pilot pressure for controlling the first control device is changed by a third control device as a function of the rotational speed of the internal combustion engine when an adjusting device is switched out of a normal operation position into an emergency operation position.

摘要： A shift-by-wire shifter assembly is provided. The shift-by-wire shifter assembly includes a shift lever, a sensor, a cable bracket, and a lever lock. The shift lever is movable between shift position locations. The sensor is operative to detect the shift position of the shift lever and generate an electrical signal corresponding to the shift position location of the shift lever. The cable bracket has a transmission shift cable mount. The lever lock is operative in a first condition to releasably interlock the shift lever to the cable bracket for movement of the cable bracket with the shift lever between shift position locations, and has a second condition in which the shift lever is movable between shift position locations independently of the cable bracket.

摘要： The device for controlling a CVT transmission which is connected with a pendulous drive, especially an internal combustion engine for a motor vehicle having front-transverse drive, has a hydromotor simultaneously used as sensor and actuator, the output signal of which is a function of the size and of the dynamics of the engine torque, the same as an electrohydraulic control unit which controls the actuating areas of the primary and secondary pulleys of the CVT via electromagnetic actuating elements and hydraulic valves. In addition to pressure-regulating valves, pressure-reducing valves and at least one emergency valve, the device has a coupling of the hydromotor with the second pressure-reducing valve via a line which coupling is used for torque modulated control of the second pressure-reducing valve in an emergency operating mode.

摘要： A powertrain has an electro-hydraulic control mechanism that provides for the establishment of six forward speeds, a neutral condition and a reverse speed. The control system also permits operation in the fifth forward range if electrical power is discontinued when the transmission is operating in the third range or higher, and permits operation in the third range if the transmission is operating in the second range or lower when an electrical power discontinuance occurs. If an electric disconnect occurs, the reverse drive is available, neutral is available, and third forward drive is available from the reverse and neutral conditions. The drive-home functions described are provided through the use of a multiplex valve, default valve and a pair of solenoid valves. The multiplex valve and default valve also permit the controlling of two mutually exclusive torque transmitting devices through the use of a single trim valve.

摘要： A control apparatus of an automated manual transmission has an input shaft provided with a plurality of drive gears, an output shaft provided with a plurality of driven gears engaged with the drive gears, and actuators for switching a transmission gear train to transmit a power from the input shaft to the output shaft. A hydraulic pressure system is provided with a control valve for regulating hydraulic pressure supplied to actuators, and an accumulator for saving working fluid and storing pressure energy. An electronic control unit determines that there occurs a trouble in the hydraulic pressure system when a rising rate of hydraulic pressure is lower than a predetermined value (S2, S3). Then, the electronic control unit switches a transmission gear train to the lowest speed gear range within a scope of no over-revolution of an engine through using pressure energy stored in the accumulator (S7, S8). Thereby, even when there occurs a malfunction in the hydraulic pressure system, a minimum drive ability can be ensured with a simple structure.
