Abstract

PURPOSE:To secure proper driving force at an uneven ground by detecting a time variation of revolution speed of a driving wheel, and when exceeding the reference variation, keeping a gear ratio of a continuously variable transmission in the proximate value, or adjusting it to the gear ratio conformed to be estimated car speed. CONSTITUTION:A control circuit C of a hydraulic continuously variable transmission TM mounted on a roadability motorcycle sets the rotational frequency of an engine E and the revolution of a driving wheel Wr to be detected as a car speed by a sensor Sc down to a control factor, controlling the transmission TM. A time variation of the revolution of the driving wheel Wr is calculated, and when exceeding the reference variation, it is so judged that overspeed of the driving wheel due to a slip and a stop of the driving wheel are caused there, whereby a gear ratio of the continuously variable transmission TM is kept in the proximated gear ratio, or a control member 27 of a hydraulic motor is adjusted so as to become the gear ratio conformed to the estimated car speed. Thus, when it gets rid of a slip state and a lock state, proper driving force is securable.
