PURPOSE: To provide a rotation speed command method to command the rotation speed of a continuously variable transmission without being influenced by a voltage drop or an external noise and to provide a rotation speed control device used for execution thereof. CONSTITUTION: A rotation speed control device comprises rotation speed control devices CRLa (CRLb, CRLc, and CRSd) to control the rotation speeds of continuously variable transmissions VSa (VSb, VSc, and VSd); a common signal wire SGL to transmit a digital signal, by which an rotation speed outputted from the rotation speed control device CRLa is commanded, to the rotation speed control devices CRLb, CRLc, and CRLd. The rotation speeds of the continuously variable transmissions VSb, VSc, and VSd are subjected to the rotation speed of the continuously variable transmission VSa. |
