摘要： An electric motor equipped with a cooling apparatus in which an oil reservoir (2b) filled with a cooling oil is provided in the lower portion of a casing (1). Provided in the casing is at least a portion of an oil passageway (2f, 4c, 28) which communicates with the oil reservoir (2b) and which opens within the casing (1) above and below a coil (6d) of the motor. The oil casing is internally provided with an oil pump (27) which causes the cooling oil to flow through the oil passageway (2f, 4c, 28). Accordingly, the cooling apparatus, which comprises the oil reservoir (2b), at least a portion of the oil passageway (2f, 4c, 28) and the oil pump (27), is provided within the casing (1) of the electric motor and integrated therewith. As a result, the electric motor is made more compact overall despite the provision of the cooling apparatus. Since the coil (6d) of the motor is positively cooled by the cooling apparatus, a large current can be passed through the coil. This enables the electric motor to generate a high output torque.

摘要： In a hybrid vehicle in which the front or rear set of wheels is driven by an engine (7) and the other set of wheels is driven by a motor (8), a traveling mode deciding unit (4) is provided with a table for deciding engine throttle opening and motor output, with driving force being distributed in accordance with the engine throttle opening and motor output decided by referring to the table. The table decides the traveling mode based on signals from a detector (2) which detects the remaining life of a battery, a vehicle velocity sensor (1) and an accelerator opening sensor (3). By deciding the traveling mode using such a table, it is possible to distribute driving efficiently in dependence upon the remaining life of the battery.

摘要： A vehicle equipment mounting structure that arranges a motor case, in which a rotary electric machine that drives a vehicle is housed, in an engine compartment, and that includes a PCU that controls the rotary electric machine, and an auxiliary battery that supplies electric power to the PCU. This structure includes a fixing portion that fixes the PCU onto the motor case, and a connecting portion that connects the auxiliary battery to a side member that absorbs an impact load by being crushed in a crushing direction. The connecting portion has a displaceable member that is displaceable in the crushing direction. The auxiliary battery is arranged on a vehicle front side of the PCU such that the PCU and the auxiliary battery partially overlap in the crushing direction. The auxiliary battery is arranged so as to be able to move past the PCU in response to an impact load.

摘要： A PCU (20) comprises an anchoring pedestal (22) that is attached to the opening of a transaxle and that has been molded from resin so as to be formed integrally with a terminal block (21); a cooler (27) that is disposed on top of the anchoring pedestal (22) and that has a power module; a heat-conductive board stay (14) connected to the top of the cooler (27); and a control board (29) connected to the top of the board stay (14). This mounting structure is configured such that by disposing the board stay (14) near a cooling tube (17a) for introducing coolant cooled by a radiator and by attaching the stay to the cooler (27) via a heat-dissipating sheet (61a) for actively conducting heat from the control board, the control board (29) is cooled by the coolant before the coolant has absorbed heat. Thus, the pressure elevation converter and inverter that form the power control unit and the motor are housed as a single component inside one case and the coolability of the control board disposed at the top of the power control unit can be ensured.
