    摘要: A continuously variable transmission, in particular for a motor vehicle, provided with a control for the transmission ratio of the transmission, which control in a first operating mode controls the transmission ratio on the basis of one or more input signals and in a second operating mode controls the transmission ratio, for example on the basis of an external signal originating from the driver of the motor vehicle, along one or more control curves of one or more sets of control curves, possibly within rotational speed limits imposed on the input speed of the transmission. One or more control curves and/or one or more rotational speed limits are a function of the input speed of the transmission in such a way that, in accordance with those functions, the input speed of the transmission is not zero for a notional output speed of the transmission of zero. In this way the drive characteristics of the transmission are appreciably improved, coupled with improved efficiency and optimum power.

    摘要: A method for controlling the transmission ratio (input speed/output speed) of a continuously variable transmission, in particular for a motor vehicle. The transmission can be set to a second operational state as a result of energization by an activation signal. In the second operational state, the transmission ratio increases or decreases in the event of a decrease of increase, respectively, in the output speed of the transmission. In the second operational state, the transmission ratio is controlled using a control line, which intersects a point determined by the instantaneous input speed and instantaneous output speed of the transmission at the instant of commencement of said second operational state and also intersects a starting point determined by an input speed equal to zero and an output speed notionally less than zero. The invention also relates to an apparatus for carrying out the method.
