    摘要: A drive system (20) for a motorised bicycle (10) which comprises an electrical motor (18) for driving the motorised bicycle (10). The electrical motor (18) has a first electric overload power limit which constitutes a limit for electrical power supplied to the electric motor (18) above which first electric overload power limit the electric motor (18) reaches a thermal overload on a long term basis. A battery (22) is provided for supplying electric drive power to the electrical motor (18) for driving the bicycle (10). The battery (22) has a second electric overload power limit which constitutes a limit of electric power drawn from the battery (22) above which second electric overload power limit the battery (22) reaches a thermal overload on a long term basis. A control unit is connected to the electrical motor (18) and the battery (22) for controlling the supply of the electric drive power from the battery (22) to the electrical motor (18) and for exclusively selecting a first level of the electric drive power from a first range of electric drive power levels. The first range of electric drive power levels has a maximum power level being equal to or smaller than the first electric overload power limit and/or the second electric overload power limit.

    摘要: 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.
