DRIVER OF ROLLING STOCK

摘要

An environment-friendly driver of series hybrid system rolling stock in which an idle stop control system for appropriately judging such a situation that an engine can be stopped and ensuring stabilized power running performance while taking account of response of engine power generation is achieved, and fuel consumption and engine noise can be reduced. A system general control section in the driver of rolling stock judges whether generation power of an engine is required or not based on the rotational speed of a generator, the rotational speed of a motor, and an internal state signal obtained from a power storage unit, and controls a power generation state by an operation command to the engine and an operation command to a converter. When generation power of the engine is not required, the system general control section judges whether the engine can be stopped or not and can deliver a command for stopping the engine by an operation command to the engine.
