摘要:
A drivable exercise machine may include an electric vehicle with human power input provided by a high output, variable-resistance, pedal-driven generator. The vehicle may include a computing device with a user interface that mimics an electric exercise bicycle. Using one or more program modes, a user may activate pre-set, custom and dynamic terrain-based exercise program profiles while commuting.
摘要:
A motor torque control device of an electrically-driven vehicle equipped with a motor serving as a driving source, is configured to limit an output of the motor when both a brake pedal and an accelerator pedal of the electrically-driven vehicle are stepped. A motor limit torque, which is an upper limit value of a command torque for the motor, is changed depending on a vehicle velocity of the electrically-driven vehicle detected by a vehicle velocity detecting unit and a stepping amount of the brake pedal detected by a brake pedal stepping amount detecting unit.

摘要:
Disclosed is a driving force control device that includes a determination section (12), a driving force command value calculation section (13), and a command value output section (14). The determination section (12) determines whether each of a plurality of motors (106), which independently drive a plurality of wheels (107), can be operated within a desired operating range when driven by a target driving force calculated for each of the motors (106). The driving force command value calculation section (13) adjusts the distribution of driving force for each of the motors in accordance with the target driving force for each of the motors and with the operating status of each of the motors and calculates an actual driving force command value for each of the motors for the purpose of operating each of the motors within the desired operating range if the determination means determines that each of the motors cannot be operated within the desired operating range. The command value output section (14) outputs the driving force command value to each of a plurality of inverters (105). Therefore, a target vehicle motion can be maximally realized while appropriately maintaining the drive status of each of the motors.

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.
