摘要： When a throttle is substantially fully open and startup is not underway, a CVT control unit (20) controls a speed ratio in accordance with a fully open speed change line. When the throttle is substantially fully open and startup is underway, the CVT control unit (20) controls the speed ratio in accordance with a fully open startup speed change line. When the throttle is substantially fully open, startup is underway, and the number of times the primary pulley rotation speed exceeds a belt assurance upper limit value exceeds an assurance frequency number, the CVT control unit (20) controls the speed ratio in accordance with the full throttle speed change line instead of the full throttle startup speed change line, even though the throttle is substantially fully open and vehicle startup is underway.

摘要： A control apparatus for a continuously variable transmission (1) that includes a belt-type continuously variable transmission mechanism (40) and friction engagement elements (32), (33) is disclosed. The control apparatus includes: an operation position detection section (65) configured to detect an operation position of a selection lever (50); a selection control section (60b) configured to execute a selection control for engaging the friction engagement elements (32), (33) from a time point at which a switching from a non-travel range to a travel range is detected; a determination section (60) configured to determine engagement states of the friction engagement elements (32, 33); and a pulley pressure control section (60c) configured to control a pulley pressure supplied to two pulleys (41), (42). A belt slippage during an engagement of clutches is suppressed while a load on an oil pump is reduced.

摘要： The invention relates to a method for controlling a continuously variable transmission with an electrohydraulic control, a selector device, and a controllable engaging clutch of a motor vehicle, especially one powered by an internal combustion engine, with a control device in a first operating mode automatically selecting and adjusting a gear ratio for the transmission from signals of the selector device and the operating parameters of the motor vehicle such as the throttle angle, driving speed and engine rpm, by means of curves selectable by the driver.It is proposed, in a second operating mode, to simulate a multi-step transmission influenceable directly by the driver. In order to permit use of this operating mode, only a few preset gear ratios are made available to the driver. In addition, from the operating parameters of the vehicle, but at least from a throttle signal value, as described in DE-OS 39 22 051, a parameter called driving activity SK(t) is obtained which evaluates the driving style of the driver or his behavior as a function of traffic situations relative to the control of the motor vehicle.The preset gear ratios are combined in groups. Depending on the driving activity SK(t) which has been determined, a group is selected. With higher driving activity SK(t), groups are selected in which the gear ratios are spread more widely and the number of gear ratios is greater. For less driving activity, SK(t) groups are selected whose spread is less and in which the number of gear ratios is smaller.
