Abstract: The present disclosure relates to an information processing device and a method, a program, and an information processing system that are designed to enhance the convenience of lending services. Information related to lending in a lending service of lending out an object is acquired from another information processing device. Information to be presented to a user is generated with the use of the acquired lending-related information, the information to be presented to the user being related to the lending service. The generated information to be presented to the user is then output. The present disclosure can be applied to information processing devices, for example.

Abstract: 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, S18) 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 (S14) in which the target speed ratio is held at a fixed value.
