Abstract: In solenoid control method and apparatus for an automatic transmission, a current signal varied in a stepwise manner is caused to pass through a filter having a predetermined transfer function, the current signal being inputted to a solenoid to drive a control valve by which a working oil pressure on at least one frictional element of the automatic transmission is controlled by reducing the working oil pressure to release the frictional element and the filter passed current signal is inputted to the solenoid to drive the control valve. The solenoid control method and apparatus described above are applicable to a change-over shift operation.

Abstract: 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.

Abstract: A cruise control system for a utility vehicle, which is speed-controlled by a hydrostatic transmission, includes a controller having an input for receiving a selectable set speed signal, and an output for sending a speed control signal to at least one proportional valve of a hydrostatic transmission servo control system. The vehicle ground speed is continuously monitored by a speed sensor operatively associated with a rotating gear in the vehicle drive train that rotates in proportion to vehicle ground speed, to create a ground speed signal. The selectable set speed signal can be input to controller memory by driving the vehicle at a desired ground speed and then activating a speed set switch. The speed control algorithm of the controller thereafter compares the set speed to the ground speed signal from the speed sensor and corrects the control signal to the proportional valve to correct hydrostatic transmission speed output.

Abstract: The oil supply with an orientation toward requirements in a transmission is implemented by a system of control and regulating modules. Mentioned in particular, here is a combined control and regulating module that is electronically driven and mechanically regulates the pressure. The controlled variable is a coil current that increases proportionally as the pressure increases. One disadvantage is that, in the case of a system failure, no coil current flows and the pressure is also minimal. In the present invention, by contrast, a maximum pressure is provided in the hydraulics even without current. This ensures that during a system failure that the operation of control elements that can only be shifted using high pressure will continue. This is implemented via a combined control and regulating module. The control unit is a magnet system that moves the regulating module and a sliding valve (14). Moreover, a spring system is provided that holds the sliding valve (14) at the starting position when no current is present.

Abstract: A clutch engaged by means of flyweights and a spring directly meshes an input sun gear and an output planet gear carrier. When engagement pressure is insufficient for torque to be transmitted, a crown wheel slows down and is stopped by a free wheel, while an axial thrust (Pac) produced by helical teeth releases the clutch, so that the device functions as a step down device. A control unit accelerates the onset of the procedure. The device enhances the comfort and reduces stresses of the transmission.

Abstract: A pilot stage of an electrohydraulic control valve controls the position of a pilot actuated main stage by controlling fluid flow through a flow path that connects a supply port to an exhaust port and to an end of the main stage. A proportional valve of the pilot stage has a valve element for establishing a variable flow control orifice to control fluid flow through the flow path and a bleed orifice disposed in the flow path downstream of the proportional valve to generate fluid pressure upstream of the bleed orifice and at the end of the main stage.

Abstract: A vehicle automatic transmission control system, in which when a gear to be shifted to is determined in response to the throttle opening and vehicle speed, hydraulic oil is supplied to a clutch for the gear to be shifted to. In an early period of the gearshift, the hydraulic oil is supplied to decrease a time lag between an output of the gearshift command and a start of clutch engagement. In the system, there is provided, instead of an expensive oil pressure sensor, a means for estimating or detecting the clutch oil pressure as a capacity of power which the clutch can transmit. When the estimated or detected pressure is high, the supply of oil to the clutch is prohibited so as to prevent sudden clutch engagement which would otherwise produce shock.
