摘要： A system for controlling the hydraulic pressure of a hydraulic control circuit of an automatic, variable speed transmission during a shift operation is provided. The hydraulic control circuit includes a plurality of hydraulic pressure control valves, a plurality of flow path switching means and a plurality of solenoid valves for controlling the engagement and disengagement of clutches and brakes in the transmission. The energization of the solenoid valves disposed in the hydraulic control circuit is controlled by an electronic system, which comprises a large scale integrated semiconductor logic unit, a semiconductor read-only memory, a semiconductor read-write memory and as required, input/output ports. The semiconductor read-only memory stores, inter alia, hydraulic pressure control program data which become operative during a selected one of the shift modes, each of which comprises a combination of the current speed stage and the speed stage to be established, and which controls the hydraulic pressure of the hydraulic control circuit by a repeated deenergization and energization of the solenoid valve for a given time interval during the shift operation.A signal indicative of a shift lever position is applied to the electronic system from a shift lever detecting means. Also a signal indicative of the current vehicle speed is applied thereto from a vehicle speed signal generating means. Finally, a signal indicative of a throttle opening is applied to the system from a throttle opening detecting means. In response to these signals and based on the constants data and the program data which are stored in the read-only memory, the electronic system determines a speed stage to be established. The hydraulic pressure in the hydraulic control circuit is controlled, simultaneously with a switching of the speed stage, on the basis of the hydraulic pressure controlling program data, thus reducing any rapid fluctuation of the vehicle speed or impulses during a shift operation.

摘要： An electronic system for controlling an automatic transmission having an hydraulic control circuit comprises a large scale integrated semiconductor logic unit, a semiconductor read-only memory, a semiconductor read-write memory and input and output ports as required. The read-only memory fixedly stores standard data indicating the upper and the lower limit value of vehicle speed which correspond to the individual throttle openings of the engine for each shift lever position of a vehicle on which the automatic transmission, the hydraulic control circuit and the electronic system are mounted; slope detecting reference data indicating the vehicle speeds on slopes which correspond to the throttle opening in each shift lever position; slope detecting program data which is utilized to detect a slope as a result of the comparison between the reference data on one hand and the current shift lever position, the current throttle opening and the current vehicle speed; additional program data which is utilized to modify at least part of the standard data in response to a slope detected to produce shift reference data which corresponds to the slope; shift determining program data which determines a speed range to be established in response to the comparison of the current speed range, the current throttle opening and the current vehicle speed against the shift reference data; and shift controlling program data responsive to the determined speed range to control the energization of the solenoid valves.In accordance with the slope detecting program data, the electronic system detects a slope, and modifies the standard data in response to the slope detected, in accordance with the modifying program data, thus producing a shift reference data, which is then written into the read-write memory. In addition, the electronic system compares against the current speed range, the current throttle opening and the vehicle speed against the shift reference data to determine a speed range to which the transmission is to be switched, generally in accordance with the shift determining program data.

摘要： A system for controlling the hydraulic pressure of a hydraulic control circuit associated with an automatic, variable speed transmission is provided. The hydraulic control circuit comprises a plurality of hydraulic pressure control valves, a plurality of flow path switching means and a plurality of solenoid valves, and operates to control the engagement and disengagement of the clutches and brakes disposed within the transmission. The energization of the solenoid valves of the hydraulic control circuit is controlled by an electronic system, which comprises a large scale integrated semiconductor logic unit, a semiconductor read-only memory, a semiconductor read-write memory and as required, input/output ports.A plurality of signals are applied to the electronic system, including a signal indicative of shift lever position supplied by shift lever detecting means, a signal indicative of the current vehicle speed supplied by vehicle speed signal generating means and a signal indicative of the throttle opening supplied by throttle opening detecting means. In response to these signals and in accordance with the program data and constants data, the electronic system determines a new gear ratio to be established. If the shift mode, defined by a combination of the current gear ratio and the new gear ratio to be established, has a likelihood to produce drive train noises, the shift controlling sub-program data is utilized to delay the timing at which the shift controlling solenoid valves are deenergized and energized, thus avoiding or reducing the occurrence of drive train noises during the shift operation.

摘要： A transmission for a vehicle includes a main transmission (M) and a differential gear mechanism (20). The main transmission has at least two rotating elements (11, 12; 13, 14) each set to a different gear ratio, and the differential gear mechanism has at least three elements (21, 22, 23). There are provided first input means (C-1, C-2) which selectively inputs an input rotation to two rotating elements of the main transmission, and second input means (1, 2, C-3; 1, 2, 4) which connects the two rotating elements to two elements (21, 22) of the differential gear mechanism and inputs the input rotation to the other at least one element (23). Since an intermediate gear ratio with respect to an individual gear ratio is generated by two rotating elements at a time of simultaneously transmitting power to two rotating elements, it is possible to increase the number of shift speeds.
