Speed ratio control device and method for belt continuously variable transmission |
摘要 |
In a speed ratio control device for a belt continuously variable transmission according to this invention, when a speed ratio is subjected to feedback control on the basis of a difference between an actual speed ratio and a target speed ratio, pressure supplied to a primary pulley is corrected through feedforward (S17, S 18) in order to suppress variation in the groove width of the primary pulley caused by a rapid variation in an input torque into the primary pulley (S17) while traveling in a fixed speed ratio mode (S 14) in which the target speed ratio is held at a fixed value. |
