Abstract: PURPOSE:To compensate a fluctuation in a car speed after control of loading and to maintain a car speed equal to a car speed before control, by a method wherein control is effected in response to loading control during running by varying the transmission ratio of a continuously variable transmission gear according to a ratio between the numbers of revolutions of a prime mover before and after loading control during running. CONSTITUTION:Since two data inputted to a comparator 17 are different from each other, an inversely proportional computer 18, based on a data A1 on the number of revolutions for running, computes the number (n) of revolutions of an engine 4 based on a step on amount of a running pedal 1, and computes the current number N of revolutions of the engine 4 in response to a detecting signal from a detector 20 for the number of revolutions. The reversely proportional computer 18 finds a ratio between the (n) and N to output it to a multiplier 22. The multiplier multiplies a transmission ratio data (n) and n/N to calculate a compensation transmission ratio data E to output the result to a slanted plate actuator 9 through a code converter 23. The inclining angle of a slanted plate is regulated, and the transmission ratio of a continuously variable transmission gear 5 is converted so as to maintain a car speed at a car speed before loading control.
