A vehicle includes a power storage device, a motor generator, a converter for stepping up an output voltage from the power storage device, an inverter for driving the motor generator, and an ECU. The inverter includes switching elements. The switching elements have a characteristic that the withstand voltage of the switching elements decreases as the temperature of the inverter decreases. The ECU sets the stepped-up voltage, based on a temperature characteristic of the power storage device and a temperature characteristic of the inverter, so that the stepped-up voltage is increased within a range in which the stepped-up voltage does not exceed the withstand voltage. In this way, at low temperatures, deterioration of the power performance can be suppressed while the switching elements are protected.

Принадлежит: Hyundai Motor Co, Kia Motors Corp

Disclosed herein is a method of controlling the travel of a hybrid electric vehicle in an emergency. It is determined whether an abnormality has occurred in a low voltage Direct Current-Direct Current (DC-DC) converter. When it is determined that an abnormality has occurred in the low voltage DC-DC converter, it is determined whether the voltage of a low voltage battery has deviated from the operational voltage range of a braking device. When the voltage of the low voltage battery has deviated from the operational voltage range of the braking device, a restricted vehicle speed is set to take into account mechanical braking power. A maximum torque used to restrict the torque of a driving motor is set based on the set restricted vehicle speed.

A trolley assist-capable electric drive truck includes a DC link with first, second and third contactors that may be opened and closed in different configurations to operate the truck in different modes. In a normal propel mode, the three contactors are open and electrical power is routed from an onboard electrical power source to electric propulsion motors. During normal retard mode, the three contactors are closed to route electrical energy generated by the electric propulsion motors through a grid resistor of the DC link. In a trolley mode, the first and second contactors are closed, but the third contactor is open, and electrical power is routed from the trolley lines to the motors for propulsion, or in a reverse direction for retarding the truck.

An electromechanical actuator power drive unit for dynamic braking is provided, comprising an electric motor with a stator, a rotor that rotates with respect to the stator, and windings fixed to the stator. There is a control unit configured to supply a current to the windings. When the control unit is not supplying current to the windings, an electrical device allows current to flow through a parallel current path to the windings. The new current is generated by the interaction of a roller connected with a gear set to the rotor. The roller, and therefore the rotor, is urged in a rotational direction by the translational velocity of a load in contact with the roller. The new current generated by the rotating rotor flows in the opposite direction as the first current supplied by the power supply unit and creates a dynamic braking torque in the electric motor. 1.
