A vehicle control device includes an identifier identifying a vehicle speed of a vehicle having a driving motor, based on a rotation speed of a power transmission shaft, and a controller controlling operation of the driving motor. The controller can switch between a normal mode of controlling acceleration/deceleration in accordance with a driver's acceleration/deceleration operation, and a cruise control mode of maintaining the vehicle speed at a target speed without being dependent on the acceleration/deceleration operation. During the cruise control mode, the controller calculates a torque command value for the driving motor by using proportional control based on a deviation between the vehicle speed and the target speed. If a prediction indicates that torsion in the shaft is to be released, the controller adjusts the torque command value such that an absolute value of torque of a proportional-control component is smaller than when the torsion is not to be released.

The present invention relates generally to an apparatus for cleaning or otherwise treating a floored surface that includes a platform adapted to support the weight of an operator.

A straddled vehicle, including a vehicle frame structure, a drive unit including a drive motor that receives electric power and outputs driving power, a driving wheel that receives the driving power, and an electric power generation unit. The electric power generation unit includes an electric power generation engine configured to output engine power, and an electric power generator that is fixed to the electric power generation engine and is electrically connected to an electric power transfer medium having flexibility. The electric power generator is configured to convert the engine power into the electric power, and supply the electric power to the drive motor via the electric power transfer medium. The straddled vehicle is series-hybridized by the drive unit and the electric power generation unit. The electric power generation engine is swingably supported, independently of the drive unit, by the vehicle frame structure, such that the engine power is not mechanically supplied to the driving wheel.

A battery module and a vehicle. The battery module includes: a unit battery; an end plate located at an end of the battery module along a length direction; and an output pole base including a mounting part and a matching part which are fixedly connected, where the matching part is made of metal material and is fixedly connected to the end plate to limit the freedom degree of movement of the output pole base relative to the end plate along the height direction, the width direction and the length direction. The plastic structure of the output pole base is added a matching part made of metal material therein and is fixedly connected to the end plate by the matching part.

In a fuel cell system which includes a high-electricity multiple-phase converter, noise generated due to an increase in reactor vibrations and due to a sound pressure increase caused by a plurality of reactors is effectively inhibited, and silence is improved. A fuel cell system includes a multiple-phase converter provided between a fuel cell and a load device. The fuel cell system includes: selecting means (e.g., a controller) for selecting a driving phase of the multiple-phase converter in accordance with the load of the load device; and driving means (e.g., a controller) for driving a plurality of driving phases, when selected by the selecting means, at carrier frequencies so that these driving phases are nearly opposite to each other.

A vehicle control apparatus includes a storage and a processor. The storage holds a first resonance map. The processor calculates a first torque command value and switches a control method of a first driving source. The first driving source includes an electric motor. The first torque command value indicates a value of torque to be outputted by the first driving source. The first resonance map includes, as one or more first resonance points, one or more operating points at which resonance occurs in an operating region of the first driving source under a square wave control. The processor switches the control method of the first driving source from the square wave control to a sine wave control on the condition that a predicted route of transition of an operating point of the first driving source meets the one or more first resonance points.

An electric motor is mounted on a body. The electric motor is driven by an electric driving unit. The electric driving unit is supported to the body by a vibration-proofing member. A natural frequency of a spring-mass system including the vibration-proofing member and the electric driving unit is higher than a frequency of a main component in vibration generated in the body during an operation.

A control apparatus for a rotary electric machine extracts, based on a rotational speed of a rotating member, a vibration component included in the rotational speed of the rotating member, the vibration component being based on vibrations of a drivetrain. The control apparatus calculates, according to the extracted vibration component, compensation torque for compensating the vibrations of the drivetrain. The control apparatus performs drive control of the rotary electric machine according to the compensation torque. The control apparatus performs suppression to suppress the rotational speed of the rotating member from changing due to change of a speed change ratio.
