A drive control apparatus to be applied to an electric vehicle includes a controller. The controller is configured to limit a change rate of a torque to be outputted from an electric motor of the electric vehicle on the basis of a first limit mode in a case where the torque is less than a threshold torque, in a period of a first traveling state in which the electric vehicle travels on an uphill road where a level of likelihood of an occurrence of a slip is estimated to be equal to or greater than a threshold, and configured to limit the change rate of the torque on the basis of a second limit mode that is more flexible than the first limit mode in a case where the torque is equal to or greater than the threshold torque in the period of the first traveling state.

The present invention relates to a method for recuperation based braking of a vehicle in which electrical energy generated during a braking process is decreased by operating at lest one second electric machine of the vehicle in a zero slip mode in order to prevent overcharging of a traction battery of the vehicle.

A traveling control apparatus includes an operation amount calculating unit for calculating the amount of operations for controlling at least one of a driving mechanism and a braking mechanism of a vehicle to make the difference between a target position and the actual position of the vehicle small; a determining unit for determining whether the actual position follows the target position; and a target position setting unit for setting the target position that changes with time passage, when it is determined by the determining unit that the actual position follows the target position. The target position setting unit sets the target position so a change in the target position with the time passage becomes smaller than that in the case where it is determined that the actual position follows the target position, when it is determined by the determining unit that the actual position does not follow the target position.

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. In addition, one embodiment of the present invention is capable of generally performing 360° turns to facilitate the treatment of difficult to access portions of the floored surface.

Systems and methods for providing locked rotor protection for powertrains of electric vehicles are provided. One method for operating an electric vehicle includes receiving a command for propelling the electric vehicle, driving an electric motor of the powertrain of the electric vehicle, and determining that the powertrain is obstructed. After determining that the powertrain is obstructed, an output is generated to initiate one or more actions intended to protect the powertrain.

The present application discloses a motor controller, a motor control method and a computer program product for vehicle assist control. An assist torque command for a motor device to perform vehicle assist control is generated according to an execution command of a vehicle assist determination unit and a rotor position signal and a rotor speed signal of a motor device. An original position signal of the motor device and the rotor position signal are calculated, and a position ratio calculation is performed to generate a front-order torque command. A torque damping command is generated according to the speed ratio calculation based on the rotor speed signal, and is calculated with the front-order torque command to generate an assist torque command. Thus, position information of the rotor of the motor device can be directly used in the calculation and speed information is at the same time used for an assist calculation, thereby preventing an error and solving the issue of sliding during parking.

A vehicle and a method for controlling the vehicle are provided. The vehicle may include a battery; and a motor configured to generate a driving force by using the electric power charged in the battery, perform a regenerative braking, and charge the battery through the regenerative braking. The vehicle identifies destination information entered in the input during the preparation of charging at the charging station, searches for a route from the charging station to the destination based on the position information of the charging station and the position information of the destination, acquires the charging amount by regenerative braking based on the road information in the searched route and the table, and stops controlling the charging of the battery when the charging amount charged in the battery is charged by the regenerative braking during charging of the battery at the charging station.

A mobile mining machine includes a plurality of traction elements, a plurality of motors, a power source in electrical communication with the plurality of motors, and an energy storage system in electrical communication with the plurality of motors and the power source. Each of the motors is coupled to an associated one of the plurality of traction elements. Each of the motors is driven by the associated traction element in a first mode, and drives the associated traction element in a second mode. The energy storage system includes a shaft, a rotor secured to the shaft, a stator extending around the rotor, and a flywheel coupled to the shaft for rotation therewith. In the first mode, rotation of the motors causes rotation of the flywheel to store kinetic energy. In the second mode, rotation of the rotor and the flywheel discharges kinetic energy to drive the motors.
