摘要： A vehicle drive device is disclosed that includes a rotating electrical machine, a transmission mechanism, an inverter device, a case including a first case portion that houses the rotating electrical machine, and a rotor shaft to which a rotor is fixed. The rotating electrical machine and a pair of output members have a two-axis configuration. The transmission mechanism includes, coaxially with the pair of output members, an output gear drivingly connected to at least one of the pair of output members. The output gear is disposed so as to overlap each of the rotating electrical machine and the inverter device as viewed in an axial direction. The inverter device is disposed so as to overlap a first output member that is one of the pair of output members, as viewed in an up-down direction. The first output member is disposed so as to overlap an axis of the rotor shaft as viewed in a horizontal direction, and the inverter device is disposed below an uppermost position of the first case portion in a second direction.

摘要： A vehicle drive device is disclosed that includes a rotating electrical machine, a transmission mechanism, and an inverter device. The rotating electrical machine and a pair of output members have a two-axis configuration. The transmission mechanism includes, coaxially with the output members, an output gear drivingly connected to the output members. A first output member that is one of the pair of output members is interposed between the rotating electrical machine and the inverter device in a horizontal direction at a position in an up-down direction where both the rotating electrical machine and the inverter device are disposed. The output gear overlaps each of the rotating electrical machine and the inverter device as viewed in an axial direction. The inverter device is disposed on the opposite side of the first output member from the rotating electrical machine and above the first output member. A case includes a peripheral wall portion that separates the first output member and the inverter device from each other. The peripheral wall portion overlaps the output gear as viewed in the axial direction.

摘要： A second gear (33) meshes with a first gear (32) and is connected to an output member (2) so as to rotate integrally with each other. A rotor (12), a planetary gear mechanism (31), and the first gear (32) are disposed on a first axis (X1) in a described order from an axial first side (L1) toward an axial second side (L2). A connecting member (6), a differential gear mechanism (4), and the second gear (33) are disposed on a second axis (X2) parallel to the first axis (X1) in a described order from the axial first side (L1) toward the axial second side (L2). The planetary gear mechanism (31) has a smaller diameter than a rotating electric machine (1) and a larger diameter than the first gear (32). The differential gear mechanism (4) has a smaller diameter than the second gear (33) and larger diameter than the connecting member (6).

摘要： A control system for a vehicle (1) provided with a differential mechanism (3) that applies a torque difference to left and right wheels (5) and two electric motors (2) coupled to the differential mechanism (3), the control system including: two control units (11, 12) being connected to each other via high-speed communication means and each controlling one of the two electric motors (2); a first rotation speed sensor (26R) that detects a first rotation speed of a first electric motor (2R) of the two electric motors (2) and outputs the first rotation speed to the two control units (11, 12); a second rotation speed sensor (26L) that detects a second rotation speed of a second electric motor (2L) of the two electric motors (2) and outputs the second rotation speed to the two control units (11, 12); and a superordinate control unit (10) that calculates demanded torques of the two electric motors (2) based on vehicle information of the vehicle (1). At least a first control unit of the two control unites (11, 12) calculates two assigned torques to achieve the demanded torques calculated in the superordinate control unit (10) based on detection signals of the two rotation speed sensors (26R, 26L).

摘要： The present disclosure discloses an integrated electric drive power assembly, which solves the problems of the electrically driving power assemblies in the prior art that have a greater axial size and greater weight. The power assembly comprises a motor and a gearbox, an output shaft of the motor and an input shaft of the gearbox are integrally manufactured, to form a main shaft (18) of the power assembly, a parking lock wheel (5) is provided within the gearbox, and the parking lock wheel (5) is fixedly mounted to the main shaft (18). The present disclosure significantly reduces the axial size of the power assembly, which facilitates the light weighing and the arrangement in the vehicle of the power assembly.

摘要： An electric vehicle drive apparatus includes a first motor, a second motor, a speed change mechanism coupled to the first motor and the second motor, and a controller controlling operation of the first motor and the second motor. The speed change mechanism includes a first planetary gear mechanism, a second planetary gear mechanism, and a one-way clutch that limits a rotation direction of a first carrier of the first planetary gear mechanism to a certain forward rotation direction. When rotating the first motor in a backward rotation direction opposite to the certain forward rotation direction and rotating the second motor in the forward rotation direction, the controller determines rotation speeds of the first motor and the second motor within a range indicated by Expression (1).

摘要： The invention relates to a vehicle drive system. There is a need for a brake responsive vehicle drive system. A vehicle drive system includes an internal combustion engine (12), an electric motor/generator (14) driven by the engine (12), and drive wheels (26,30) driven by traction motor/generators (24,28). The motor/generators (24,28) are controlled by a controller (40) which receives signals from an operator speed control member (36), wheel speed sensors (46,48), and a pair of brake pedal position sensors (58,60), each connected to a corresponding left or right brake pedal (57,59). In response to operation of the brake pedals (57,59), the controller (40) coordinates operation of the electric drive system with operation of the brake pedals (57,59).
