摘要： Motor-generators are incorporated in front wheels and drive the front wheels, respectively. An ECU determines whether or not a steering apparatus including a steering actuator, a tie rod and a steering angle sensor has failed, based on an operation angle of a steering wheel from a steering wheel angle sensor and a steering angle of the front wheels from the steering angle sensor. When the ECU determines that the steering apparatus has failed, the ECU provides torque difference for a torque instruction for the motor-generators in accordance with the operation angle of the steering wheel.

In each of rotor slots formed between the main salient poles adjacent to each other in the circumferential direction, the auxiliary salient poles adjacent to each other in the circumferential direction are connected to each other within the rotor slot. In each rotor slot, at least a portion of the rotor windings is disposed radially inside the auxiliary salient poles.

摘要： A battery is arranged outside a compartment. A service plug is arranged in the compartment. The service plug is a shutoff device that can shut off an output path of the battery by a manual operation. When a vehicle is hard hit at the front and a circuit of PCU is damaged, an excessive current may flow to the PCU, possibly generating heat or smoke from the PCU. When the vehicle goes wrong, a person on board the vehicle may pull out the service plug, whereby the power supply path from battery to PCU can be shut off.

摘要： A vehicle drive device includes a motor generator (MG2), a power control unit controlling the motor generator (MG2), and a case housing the motor generator (MG2) and the power control unit. The power control unit includes a first inverter driving the motor generator (MG2) and a voltage converter boosting a power supply voltage to apply the voltage to the first inverter. A reactor L1 which is a component of the voltage converter is disposed such that at least a portion of a core comes into contact with the case for heat exchange. Consequently, the heat is dissipated to the case having a large heat capacity for integral housing, to thereby allow the heat dissipation performance of the reactor (L1) arranged in the limited space to be ensured.

摘要： Right front wheel units (FL, FR) are driven independently by motor generators (MGL, MGR). A power control unit (1) is provided common to the motor generators (MGL, MGR) and integrally controls driving them. Each motor generator (MGL, MGR) and the power control unit (1) are selectively connected by switch circuits (SWL, SWR). The switch circuits (SWL, SWR) are switched by an ECU (3), as appropriate, in accordance with how the vehicle (100) is currently traveling (i.e., a driving force that the vehicle is required to output, and a direction in which the vehicle is traveling). In other words, the vehicle (100) can selectively implement traveling with the left and right front wheel units (FL, FR) both serving as driving wheel units, and traveling with only one of the left and right front wheel units (FL, FR) serving as a driving wheel unit, depending on how the vehicle is currently traveling.
