摘要： An automatic transmission of a motor vehicle, comprising a plurality of planetary gear units; a plurality of frictional elements, the frictional elements assuming engaged/disengaged condition upon receiving a ratio change instruction thereby to establish a desired speed of the transmission with the aid of the planetary gear units; a deceleration detecting means that detects a deceleration of the motor vehicle; a gear ratio detecting means that detects an actual gear ratio that is actually established in the transmission; and an interlock judgment means that judges whether or not the transmission is subjected to an interlock, the interlock being a condition wherein upon receiving the ratio change instruction, at least one of the frictional elements is brought into unintended engagement. The interlock judgment means is configured to carry out judgment of the interlock by analyzing a deceleration of the vehicle and a relation between a gear ratio intended by the ratio change instruction and an actual gear ratio actually established by the transmission while the transmission is not under a ratio change.

摘要： A closed loop adaptive fluid control system and method for use in hydraulic applications monitors one or more fluid characteristics, such as pressure, flow rate, accumulation time in an actuator, fill volume, etc., and compares the characteristic with a target response. A fluid characteristic sensor detects at least one fluid characteristic at a hydraulically-actuated device that is actuated by a electrically-operated. The sensor sends a device signal corresponding to the actual sensed characteristic to an electronic controller, which compares the device signal with a target response. The controller then identifies any differences between the device signal and the target response and provides a feedback signal to the electrically-operated valve to adjust the current to the valve, which in turn adjusts the electrically-operated valve so that the device signal corresponding to the sensed characteristic at the device converges toward the target response.

摘要： A hydraulic control apparatus of a vehicular automatic transmission has a plurality of hydraulic friction engagement devices that are selectively engaged and released to establish a plurality of forward speed change stages of different speed change ratios. The forward speed change stages are achieved through engagement of predetermined friction engagement devices, of the plurality of friction engagement devices. If it is determined that a predetermined speed change stage corresponding to a predetermined shift output is not established, the hydraulic control apparatus identifies a hydraulic friction engagement device having a bad engagement that is a cause of the non-establishment of the predetermined speed change stage, on the basis of the state of engagement oil pressure of the predetermined friction engagement device.

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： There is provided a hydraulic control device for an automatic transmission, which is comprised of an engagement state determining section and a protection control section. If the engagement state determining section determines that each clutch, which is supplied with a line pressure via a regulating valve having a spool and has an oil pressure switch disposed in an oil channel, is held in an engaged state when gears are not changed, the protection control section sets a command pressure for the regulating valve to a protective oil pressure lower than the line pressure. This brings the regulating valve into a pressure-regulating state to cause lands of the spool to form apertures that reduce hydraulic vibration applied to the line pressure. This inhibits an oil pressure beyond an acceptable value from being applied to the oil pressure switch, and therefore improves the durability of the oil pressure switch.

摘要： The present invention provides a method and apparatus for controlling the pressure of an actuating fluid flowing through an inching clutch. The invention includes the steps of determining an actual pressure of the actuating fluid, establishing an inching pressure threshold, comparing the actual pressure with the threshold, and controlling the actual pressure in response to the comparison. In one embodiment, the pressure is controlled using a first control algorithm in response to the fluid pressure being less than an inching threshold, and using a second control algorithm in response to the pressure being greater than or equal to the inching threshold.

摘要： A hydraulic pressure control device for an automatic transmission in which a single control valve selectively applies control pressure to friction elements includes a control valve and a shift valve. The control valve has a control port from which control pressure is outputted after being adjusted by a linear solenoid valve, and first and second feedback ports to which the control pressure is fed back. The shift valve is positionable in a first position when the control pressure is applied to the first friction element and a second position when the control pressure is applied to the second friction element, and is adapted to lower the control pressure outputted by the control valve in the second position of the shift valve by controlling communication of the control port with the feedback ports. In addition, an ON-OFF solenoid valve switches the position of the shift valve.

摘要： The invention provides a shift control apparatus of a working vehicle in which an excellent shift operability can be obtained without reference to an incline of a travelling road, a loading amount and a road condition without necessity of learning a time for controlling an engine. Accordingly, a controller outputs a command for setting a hydraulic pressure (Pn) of a clutch before a shift operation to 0 value at a time of starting the shift operation and a command for making a hydraulic pressure (Pa) of a clutch after the shift operation be gradually increased in point of time to an electromagnetic proportional control valve (16), changes a fuel injection amount command signal (Fi) to a fuel injection apparatus (19) from an accelerator injection amount signal (THo) on the basis of an accelerator pedal operating amount to a synchronous injection amount signal (THc) for controlling an engine rotational speed so that an absolute value of an input shaft conversion relative speed (Nr) is reduced, and changes the fuel injection amount command signal (Fi) from the synchronous injection amount signal (THc) to the accelerator injection amount signal (THo) when the absolute value of the input shaft conversion relative speed becomes smaller than a predetermined threshold (dNr).
