VEHICLE CONTINUOUSLY VARIABLE TRANSMISSION CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a vehicle continuously variable transmission control system capable of improving the fuel economy of a vehicle incorporating therein a belt continuously variable transmission and increasing the degree of freedom for the setting of acceleration characteristics.SOLUTION: A vehicle continuously variable transmission control system 12 comprises: a continuously variable transmission 68 that includes a belt wound on a power-source-side drive pulley and a wheel-side driven pulley, and an electric actuator 106 axially moving a movable sheave of at least either the drive pulley and the driven pulley axially and changing a width between the movable sheave and a fixed sheave; a control unit 70 controlling the electric actuator 106 to be driven; and acceleration operation detection means detecting an operation state of an acceleration operation unit. The control unit 70 controls the electric actuator 106 to axially move the movable sheave so that a gear reduction ratio of the continuously variable transmission 68 becomes lower as a control input of the acceleration operation unit is greater at least in a predetermined control input range.
