POWER TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a power transmission system that can reduce power consumption of a specific auxiliary machine that performs power running operation.SOLUTION: An ECU 50 can control the operation of a specific auxiliary machine 11. Request torque calculation means 51 calculates request torque being torque which is to be output from the specific auxiliary machine 11. Stationary operation control means 52 controls the specific auxiliary machine 11 so that stationary operation torque that is the torque output from the specific auxiliary machine 11 becomes the request torque by making the specific auxiliary machine 11 perform power running operation at all times during "a first prescribed period being a prescribed period". Intermittent operation control means 53 alternately repeats, within "a second prescribed period being a prescribed period", "high torque operation control for making the specific auxiliary machine 11 perform power running control and controlling the specific auxiliary machine 11 so that torque greater than the request torque is output" and "stop control for controlling the specific auxiliary machine 11 so that the specific auxiliary machine 11 is stopped", and controls the specific auxiliary machine 11 so that the average of the torque output from the specific auxiliary machine 11 becomes the request torque.
