    摘要: An electric drive apparatus includes a controller for controlling an electric motor and a continuously-variable transmission connected with the motor. The controller controls the motor and the continuously-variable transmission in a first control mode to control the transmission ratio of the continuously-variable transmission to a predetermined fixed ratio so as to hold the transmission ratio at the fixed ratio, and to control the motor to achieve the demand motor torque when a demand motor operation point determined from a predetermined assumed ratio is within a predetermined operation range, and to control the motor and the continuously-variable transmission in a second control mode to vary the transmission ratio and to control the motor to achieve a desired driving torque for a driven member driven by the motor when the demand motor operation point is not within the predetermined operation range.

    摘要: A control device for a belt continuously variable transmission with a primary pulley, a secondary pulley and a V-belt, includes an oil pressure control unit which applies a thrust to each of the primary pulley and the secondary pulley, and a controller. The controller judges whether or not a pulley ratio is less than 1. When the pulley ratio is less than 1, the controller sets a target thrust of the secondary pulley on the basis of an input torque to the primary pulley and a coefficient of static friction between an element forming the V-belt and the secondary pulley, and then to instruct the oil pressure control unit to apply the target thrust to the secondary pulley. When the pulley ratio is at least 1, the controller sets a target thrust of the primary pulley on the basis of the input torque to the primary pulley and a coefficient of dynamic friction between the element forming the V-belt and the primary pulley, and then to instruct the oil pressure control unit to apply the target thrust to the primary pulley.
