A call admission control system in an asynchronous transfer mode exchange includes a unit for describing attribute parameters of a cell from the subscriber terminal; a unit for calculating, based on the attribute parameters, the average and the dispersion of the traffic speeds of the call; a unit for managing data of the average and the dispersion on each output route and data relating to each subscriber; and a unit for calculating the total average and the total dispersion of the data speeds on the selection output route; and a unit for calculating prediction values of cell abandon rate and end-to-end delay based on the average and the dispersion on the selected output route calculated by the total average and dispersion calculating unit, and for comparing the prediction values with the required service quality of cell discard rate and end-to end delay, for determining whether or not the requesting call may be connected.
摘要:
A system and method for controlling an operation of an internal combustion engine of a vehicle having an automatic transmission in which at least one of predetermined fuel supply recovery engine revolution speed or predetermined fuel supply cut-off engine revolution speed is varied during the engine deceleration condition according to a state of operation of the automatic transmission. In the first preferred embodiment, a downshift operation of the automatic transmission is detected. In the second preferred embodiment, an overrun clutch solenoid is turned on (energized). In the latter case, both fuel supply recovery and fuel supply cut-off engine revolution speeds are set to higher values than those when the clutch solenoid is turned off (deenergized).

A hydraulic pressure, i.e., a line pressure, of a hydraulic fluid supplied from an engine driven pump toward a hydraulically actuable coupling of an automatic transmission is held at the maximum pressure value when a temperature of an automatic transmission oil is less than a predetermined temperature value. However, the hydraulic pressure is temporarily decreased from the maximum pressure value to the minimum pressure value for a period of time after cranking of the engine when the transmission oil temperature is lower than the predetermined temperature value. Owing to a decreased load on the engine by the oil pump, smooth cranking and subsequent warming-up operation of the engine is assured under cold whether condition when the automatic transmission oil temperature is lower than the predetermined temperature value.
摘要:
There is disclosed a system for controlling an automatic transmission with which an automotive engine is incorporated. The system comprises a first control unit which controls an ignition timing of the engine in accordance with an octane value of gasoline on which the engine is operated; a second control unit which controls a gear change point of the transmission and controls a line pressure of the transmission in accordance with a given factor of the fuel; and a correcting unit which corrects the line pressure in accordance with the octane value of the gasoline.
摘要:
An engine output characteristics control system includes means for monitoring a selection of speed ratios of a power transmission to provide information concerning transmission gear position. The control system receives transmission gear position indicative information to detect selection of a specific speed ratio of the transmission for providing information indicative of the selection of the specific transmission gear position. The control system is responsive to the specific transmission gear position selection indicative information for deriving an engine control signal for controlling the engine output characteristics so that the engine output is adapted to the specific speed ratio.
摘要:
A belt device includes a belt configured to rotate, a plurality of stretch rollers configured to stretch the belt wound around the plurality of stretch rollers, and a belt alignment mechanism configured to align the belt. At least one of the plurality of stretch rollers has a diameter at a center greater than diameters at both ends in an axial direction of the at least one of the plurality of stretch rollers. The diameter at the center and the diameters at both ends are different from a diameter of the other of the plurality of stretch rollers.
