An object is to provide an electric train car controlling device that can reliably detect an idling state or a sliding state and suitably perform a torque control even when an acceleration change or a deceleration change is too small to be detected using an acceleration deviation or a deceleration deviation that appears in acceleration or deceleration of an electric train car. A first threshold (±1) is determined, with reference to an absolute acceleration that is determined in accordance with a vehicle usage condition, to detect an acceleration change generated in acceleration (S2) of a self-axle speed that is a maximum speed (a minimum speed in a decelerating operation) of revolving speeds of plural motors that drive plural driving wheel axles. When the acceleration (S2) exceeds the first threshold (±1), a system for generating a target torque command value reduced in accordance with the acceleration deviation is separated by setting an output (S3) of a comparator circuit to level "0", and a first-order delay circuit (14) outputs the target torque command value (TP) subjected to a reduction process during a processing period designated by an output (S4) of a delay time generating circuit. |
