摘要： A vehicle includes a transmission having a first neutral with a first combination of engaged clutches and a second neutral with a second combination of engaged clutches. The second neutral has more engaged clutches than the first neutral. A vehicle controller is programmed to, in response to a request to shift from the first to the second neutral and a failed-on clutch being detected, inhibit the shift to remain in the first neutral.

摘要： A vehicle includes a powertrain having an electric machine operatively coupled to a transmission and selectively coupled to an engine, and a controller. The controller, while operating the powertrain in an electric mode and in response to an accelerator pedal position initiating a transmission ratio change that results in a request to operate the powertrain in a hybrid mode and an engine start fault, outputs a cancellation request to cancel the transmission ratio change.

摘要： A hydraulic control system adapted to carry out a speed change in case of rotating a wrapping transmission under the situation where solenoid valves for controlling a pressure in a hydraulic chamber cannot be energized.A pair of pulleys individually provided with hydraulic chambers to vary a width of a groove holding a belt. Those hydraulic chambers are connected with a hydraulic source through electrically controlled feeding control valves, and also connected with drain portions through electrically controlled relief control valves. The hydraulic control system includes a communicating passage connecting the hydraulic chambers, and the hydraulic control system disconnects the hydraulic chambers from the hydraulic source and the drain portions in case none of the feeding control valves and the relief control valves can be energized.

摘要： There is provided a circuit configuration which does not require an additional fail-safe mechanism caused by the addition of a changeover valve in a hydraulic pressure control device for an automatic transmission having a function to directly supply a line pressure and hold (lock) an engaging pressure by combinations of electromagnetic valves and changeover valves.A changeover valve 20 is disposed between an output port 12 and a feedback port 13 of a linear solenoid valve 10 of the hydraulic pressure control device for an automatic transmission. The changeover valve 20 operates depending on at least an output pressure from the output port, and is switched between (1) a first state (control mode) in which a pressure Pc corresponding to an indicator current is outputted through the linear solenoid valve 10 by bringing the output port into communication with the feedback port, and (2) a second state (lock mode) in which a line pressure PL is outputted through the linear solenoid valve 10 by bringing the feedback port 13 into communication with a drain passage EX and discharging oil from the feedback port.

摘要： A method of controlling driveshaft speed includes generating an overspeed protection action signal if an engine speed limit and a requested transmission gear ratio correspond to a driveshaft overspeed condition. An operating method for a machine includes disengaging a relatively higher transmission gear, and inhibiting re-engagement of the higher transmission gear responsive to an overspeed protection action signal. An electronic controller for the machine is configured to generate an overspeed protection action signal responsive to an engine speed limit and requested transmission gear ratio.

摘要： In a transfer drive mode switching control system employing a shift actuator that switches from one of a plurality of drive mode positions of a transfer to the other, a drive mode position sensor is provided to detect the drive mode position switched by the shift actuator and to generate information regarding the drive mode position. A transfer control unit outputs a control command signal based on the drive mode position information to the shift actuator for controlling switching between the drive mode positions responsively to a driver-selected drive mode. The transfer control unit allows only a switching operation between predetermined two different drive mode positions corresponding to both ends of a working range of the shift actuator at which motion of the shift actuator is stopped mechanically, in presence of a failure in the drive mode position sensor.

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.
