Title:
BELT TRANSMISSION SYSTEM
Document Type and Number:
Japanese Patent JP2017125565
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a belt transmission system capable of reducing vehicle vibration in engine operation including engine starting.SOLUTION: A belt transmission system 10 includes a rotary angle sensor 41 detecting a first pulley position as a relative position of a first tensioner pulley, and a control device 20 for controlling torque of a motor 11 to suppress change of the first pulley position and a second pulley position. In the belt transmission system 10, fluctuation of the torque added to a crank shaft 91 can be grasped by change of the first pulley position and the second pulley position. By utilizing the same, the control device 20 controls the motor torque to suppress the change when the first pulley position and the second pulley position are changed, to implement torque application and torque absorption having reverse phase to the fluctuation of the torque added to the crank shaft 91. Thus vehicle vibration can be reduced in operation of an engine 90 including engine starting.SELECTED DRAWING: Figure 1
