摘要： Die Erfindung betrifft ein Verfahren beim Anwählen einer Gangstufe bei einem Fahrzeug-Automatikgetriebe mit zumindest einer Vorwärtsgangstufe und einer Rückwärtsgangstufe, bei dem bei bestimmten Betriebsbedingungen ein Schaltvorgang von der Vorwärtsgangstufe in die Rückwärtsgangstufe oder umgekehrt ignoriert wird. Die Aufgabe, Fehlbedienungen bei der Betätigung eines Automatikgetriebes zu vermeiden und den Fahrkomfort zu erhöhen, wird dadurch gelöst, daß der Schaltvorgang bis zu einer bestimmten ersten Geschwindigkeit des Fahrzeugs durchgeführt wird, daß in einem Geschwindigkeitsbereich des Fahrzeugs zwischen der ersten und einer zweiten Geschwindigkeit beim Schaltvorgang lediglich eine neutrale Gangstufe eingelegt wird und daß der Schaltvorgang oberhalb der zweiten Geschwindigkeit ignoriert wird.

摘要： A shift interlock mechanism for an automatic transmission includes electro-hydraulic elements (40,42) internal to the transmission which are operable to inhibit the supply of fluid pressure for engaging the forward and reverse speed ranges of the transmission. The electro-hydraulic elements are activated in response to various operating parameters of the vehicle, including range selector position, engine throttle position, depression of the service brake pedal, vehicle speed, etc. The mechanism does not interfere with movement of the transmission range selector, and includes a mechanical link (90) for overriding the interlock function when the range selector is moved to a LO forward range, thereby providing an override in the event of a failure of the electro-hydraulic elements.

摘要： A hydraulic control apparatus for a vehicle power transmission for transmitting power from an engine to a drive wheel a reversing mechanism (16) having a reverse position established by a hydraulic actuator (70). The apparatus includes a reverse inhibit valve (420) disposed in a hydraulic line leading to the hydraulic actuator and having a reverse inhibit position for inhibiting the mechanism (16) from being placed in the reverse position and a non-inhibit position for permitting the mechanism to be placed in the reverse position. The apparatus uses a first and a second pilot pressure generating device (344, 346; 392, 394) for producing a first and a second pilot pressure (Psol4, Psol5), respectively. A relay valve (380) is provided for producing a first hydraulic signal for establishing the reverse inhibit position of the reverse inhibit valve, based on one of combinations of operating states of the two pilot pressure generating devices, and a second hydraulic signal for establishing the non-inhibit position, based on the other combinations.

摘要： Disclosed is an automatic control system for a powershift, preselect transmission (10) including a plurality of power paths (36, 38) alternately connectable between input (12) and output (20) shafts by first engaging selected ones of synchronizer clutches (42, 74, 84) associated with each of a plurality speed ratio gears (44,46,76,78,80) in each path and then alternately engaging a powershift clutch (48, 82) associated with each path. The control system includes a hydraulic logic system (118) which may be electronic and a hydraulic and shift valve system which may be electrically controlled should the logic be electronic. The control system preselects ratio gears in a nondriving path and then alternately engages the powershift clutches to switch driving connections from one path to the other. The logic system includes an improved reverse sequence valve (132) and improved shift valves (124, 126, 128). The shift valve system includes the feature of trimmer valves (364, 370, 372, 374) to control the engagement rate of the synchronizer clutches and combination trimmer valves (360, 366) to control the engagement rate of the powershift clutches. The logic system further includes the feature of a reverse sequence valve (132') for preselecting reverse as a function of speed and independent of the shift selector position.

摘要： There is provided a control apparatus for a vehicular automatic transmission which reliably inhibits switching between ranges caused by an erroneous operation of a shift lever and enables a vehicle to continue running normally without interfering with the operation of returning the shift lever to a normal position. When the shift lever is switched to a reverse range in a state in which a flag Flag_D_high indicative of a forward high vehicle speed assumes "1", this operation is determined as being an erroneous operation, and gear shift to a reverse gear position is inhibited from being accomplished. When the shift lever is switched to a forward range in a state in which a flag Flag_R_high indicative of a reverse high vehicle speed assumes "1", this operation is determined as being an erroneous operation, and gear shift to a forward gear position is inhibited from being accomplished. When the shift lever is returned to the previous range while accomplishment of gear shift to the reverse gear position or the forward gear position is inhibited, the inhibition is terminated to provide normal control, so that the vehicle can continue to run normally in the range suited to the driving condition before the erroneous operation.
