A battery-powered motor may include an electric motor, a controller, and a housing. The electric motor may be wound to enable the battery-powered motor to achieve a non-limited motor maximum motor revolutions per minute (RPM) for at least one specified battery. The controlling current may include limiting current to the electric motor at lower RPMs, and limiting the current to prevent the RPM of the electric motor from exceeding a limited maximum motor RPM which is lower than the non-limited motor maximum RPM. The housing may enclose the electric motor and the controller and the specified battery. The housing may have a form factor to engage with a machine that engages with an internal combustion engine that has a maximum engine RPM that is approximately the same as the limited maximum motor RPM.

The present disclosure relates to a method and a device for safety driving. The method includes: acquiring riding data of a current user of a self-balancing vehicle; comparing the acquired riding data with riding data corresponding to a plurality of preset user levels; and determining a user level of the current user of the self-balancing vehicle according to a result of the comparing. The riding data includes one or more of the following data: a riding time, a riding distance, a shaking frequency, a shaking arc magnitude, and a shaking time.

A control apparatus includes: a data acquisition part that is configured to acquire torque data indicating a drive torque of an electric motor, rotation number data indicating a rotation number of the electric motor, and DC voltage data indicating a DC voltage supplied to an inverter which supplies an AC current to the electric motor; a determination basis derivation part that is configured to derive a determination basis based on a drive efficiency of the electric motor by using the torque data, the rotation number data, and the DC voltage data; and a control method determination part that is configured to determine, based on the determination basis, which one of a one-pulse control and a pulse-width modulation control is employed as a control method of the inverter.

An off-road vehicle has four wheels and side-by-side driver and passenger seats. At least two of the wheels are driven by an electric motor powered by batteries disposed in the vehicle.

A control system for an electrified powertrain of a battery electric vehicle (BEV) includes an accelerator pedal and a controller configured to determine maximum and minimum values for driver pedal position based on a first position of the accelerator pedal indicative of a first driver pedal position, determine whether the accelerator pedal position remains constant relative to the first position, when the accelerator pedal position does not remain constant and moves to a second position indicative of a second driver pedal position, detect that driver pedal position is increasing when the second driver pedal position is greater than the first minimum value and setting the first maximum value to the second driver pedal position and detect decreasing driver pedal position when the second driver pedal position is less than the first maximum value and setting the minimum value to the second driver pedal position.

A control apparatus for a vehicle, is mounted on an automobile that has a motor for traveling and a power storage apparatus for exchanging electric power with the motor. The control apparatus is configured to execute external charging for charging the power storage apparatus by using electric power from an external power supply, and is configured to perform a route guidance for a planned travel route to a destination. When operation information on a charging spot of the destination is not obtainable and it is predicted that the charging spot of the destination is not usable, it is recommended to execute the external charging at a charging spot around the planned travel route.

A braking force control apparatus in a motorcycle, includes a controller which controls a transmission to reduces driving force of an engine by a predetermined speed reduction ratio and transmits the driving force to a drive wheel of a vehicle, a clutch between the engine and the transmission, and brake devices which generate braking force on the wheels. The vehicle is switchable between a normal and a slow speed driving modes. In the slow speed mode the controller detects an inclination pitching angle θ, and causes the brake devices to generate braking force on at least one of the drive wheels when θ≧a predetermined value, then starts switching the clutch to a connected state when a driving operation is input, and gradually releases the braking force once driving force starts to be transmitted to the drive wheel.
