Abstract: The present invention is to provide a cooling flow amount control system and method, which can efficiently cool an object to be cooled of a green vehicle by predicting a temperature rise of the object to be cooled (motor, inverter, converter, etc.) in correspondence to the electrical and electronic equipment requiring water cooled type cooling in advance based on the running conditions of the vehicle in order to increase the cooling flow amount. According to an embodiment of the present invention, a method to cool the electrical and electronic equipment to be cooled in the green vehicle may comprise the steps of: determining whether a drive torque or a drive torque command value are equal to or greater than a set value; determining whether a regenerative braking torque is equal to or greater than the set value; and increasing the cooling flow amount by driving a pump if the drive torque, the drive torque command value, or the regenerative braking torque are equal to or greater than the corresponding set value.

Abstract: PURPOSE: A device for reducing vibration and noise of speed reducer for a fuel cell drive system which combines multiple output shafts of different motors is provided to successively perform the output direction conversion of multiple motors by giving a uniform delay time to a control current of a motor controller. CONSTITUTION: Motor controllers(14a,14b,14c) control motors(12a,12b). A reduction device(20) is connected to the output end of each motor. The control current having different phases is applied in three motors from the motor controller. The output direction of the three motors is successively converted by the control current having different phases. Gear collision due to a gear backlash of the gears of the reduction device connected to each motor is successively performed.
