Abstract: The present invention provides a shift control method implemented in a vehicle equipped with an automatic transmission for controlling an input shaft rotation speed to a target input shaft rotation speed during a shift. The method includes setting of a basic target synchronization rotation speed that is a basic target value of the input shaft rotation speed during the shift, and setting of a corrected target input shaft rotation speed as the target input shaft rotation speed when the shift is a downshift without a requirement for a driving force of the vehicle, The corrected target input shaft rotation speed is obtained by decreasingly correcting the basic target synchronization rotation speed. Further, a decreasing correction amount of the basic target synchronization rotation speed is set so as to become larger as a deceleration of the vehicle becomes larger.

Abstract: Provided is a collected current monitoring device. A transformer current acquisition unit acquires a current value Ip of a current flowing through a part of a plurality of transformers. A total collected current calculation unit calculates a current value Iall of a collected current supplied by a plurality of current collectors from the current value Ip by using a following Equation (1): Iall=Ip×(Mall/Mp). A collected current acquisition unit acquires a current value IX of a collected current supplied by the current collector(s) other than one current collector. The collected current calculation unit calculates a current value IY of a collected current supplied by the one current collector by subtracting the current value IX from the current value Iall.

Abstract: The present disclosure provides a collected current monitoring device installed on a railroad vehicle comprising a first current collector and a second current collector. The collected current monitoring device comprises a detector that detects a first current flowing to the first current collector and a second current flowing to the second current collector, and a determiner that determines whether it is necessary to control collected current of the railroad vehicle based on the first current and the second current detected by the detector. The determiner determines that it is necessary to control the collected current when a sum of a first non-energized time during which the first current is not flowing and a second non-energized time during which the second current is not flowing in a specified counting time exceeds a threshold value.
