摘要： The automatic transmission of the present invention prevents fluctuation of torque transmission through a band brake. In the hydraulic operator for the band brake, a resilient elastic cushion is provided between a rod abutting one end of the band of the band brake and a piston. Any slippage between the band and drum of the band brake will result in oscillation of the rod. However, the elastic cushion absorbs oscillation of the rod, thereby isolating the piston from that oscillation.

摘要： There is provided control over transmission stages which suppresses unnecessary shifts to a higher speed based on road information stored in a navigation system to allow smooth acceleration. An intersection ahead of the vehicle in the traveling direction is detected based on the road information stored in the navigation system and, when the vehicle is decelerated as it approaches the intersection, an optimum transmission stage for acceleration is selected in advance in accordance with the speed of the vehicle by predicting the acceleration to be performed when exiting the intersection. This eliminates the need for a shift to a lower speed before effecting acceleration by pressing the accelerator and thereby ensures smooth acceleration.

摘要： A neutral start switch has a base on which stationary contacts are arranged and a rotor on which movable contacts capable of contacting the stationary contacts are disposed. The stationary contacts include reverse lamp contacts connected to a reverse lamp lighting circuit, position stationary contacts connected to a position signal circuit provided in an electronic control device, and starter stationary contacts connected to a starter motor driving circuit. The contacts are arranged so that contact portions of the movable contacts that contact the reverse lamp stationary contacts are different from contact portions of the movable contacts that contact the other stationary contacts, thereby preventing carbonized powder produced by spark at the time of the closure and opening of the reverse lamp contacts from causing a contact failure of another contact.

摘要： In order to improve transmission efficiency of an automatic transmission, an engagement brake which does not cause drag is used and the surety of its engagement and release, and quick switching between forward maneuver and backward maneuver, is enabled. The automatic transmission comprises a transmission mechanism to achieve forward maneuver and backward maneuver. A backward motion brake which stops the rotation element to achieve backward maneuver is the engagement brake and an input clutch to transfer power by meshing with the rotation element during both forward maneuver and backward maneuver is a friction clutch. The control apparatus executes the control operation to prepare for speedy re-meshing by holding a supply pressure for the clutch hydraulic servo at a sufficient oil pressure to place the pressure in the stand-by condition at the piston stroke position immediately before the start of clutch engagement during the engagement or releasing of engagement of the engagement brake at the time of D.fwdarw.R or R.fwdarw.D shift.

摘要： A control system for use in an automatic transmission having a transmission mechanism for establishing a plurality of forward stages, a neutral state and a reverse stage. The transmission mechanism includes a predetermined rotary element to be retained for establishing the reverse stage; a reverse brake for retaining the rotary element; and a frictional engagement element capable of stopping the rotation of the rotary element. The reverse brake is a meshing type brake which meshes with and retains the rotary element. The control system has an engagement mechanism for applying the frictional engagement element. When the reverse stage is selected, the frictional engagement element is applied at least until the meshing engagement of the reverse brake is established, to stop the predetermined rotary element.

摘要： In a CVT transmission with planetary gear operation in forward, zero and reverse directions, reduction in CVT secondary/primary pulley ratio is inhibited when the pulley ratio is less than a set pulley ratio which is higher than the pulley ratio producing zero output rotation (a gear-neutral state). In a ratio region below the set pulley ratio, a movable sheave of a primary pulley is moved to an O/D side. The amount of the movement is detected by a sensor shoe (detecting means) which is associated with the movable sheave. A ratio sensing valve (inhibition means) associated with the sensor shoe, in turn, clogs a port, halting a hydraulic pressure supplied by a primary regulator valve. As a result, no hydraulic pressure is supplied to the second hydraulic chamber by way of a down-shift relief valve, a manual valve or a low-high control valve, inhibiting a down shift.

摘要： An automatic transmission control apparatus has first and second hydraulic servos for engaging forward and reverse driving friction engaging elements, respectively, a fluid pressure control unit, a range shift detector, and an electronic control unit. When the forward driving range is selected, the fluid pressure control unit supplies a forward driving range pressure to the hydraulic servo via a changeover valve operated by a signal pressure from a normal open-type solenoid valve, when the signal pressure is drained. When the reverse driving range is selected, the electronic control unit outputs a signal to magnetize the solenoid valve. The solenoid valve is thus turned on to discontinue the drain. The control apparatus thus prevents low pressure in the reverse driving range pressure to prevent delay of engagement of the clutch.
