摘要： The clearance between the stator pole portions and the rotor pole portions at the axial central portion is larger than the clearance therebetween at the axial end portions. According to these characteristics, the magnetic attracting force causing objectionable acoustic noise is increased at the axial end portions of the housing and the stator in which stiffness against the magnetic attracting force is high and decreased at the axial central portion in which their stiffness against the magnetic attracting force is low. Thereby, the objectionable acoustic noise is reduced without changing the motoring torque and increasing the weight of the switched reluctance motor.
摘要翻译：在轴向中心部分处的定子极部和转子极部之间的间隙大于轴向端部处的间隙。根据这些特性，在壳体和定子的轴向端部处引起引起令人不快的声学噪声的磁吸引力增加，其中抵抗磁吸引力的刚度高且在轴向中心部分处减小，在轴向中心部分处，其抵抗磁性的刚度吸引力很低。因此，不改变电动转矩并增加开关磁阻电动机的重量，可以减少令人反感的噪音。

摘要： Front left and right wheel units are driven by an engine and a motor generator. Rear left and right wheel units are independently driven by in-wheel motor type motor generators. The motor generator and the motor generator are configured to have different rated outputs, respectively, and be subjected to different speed reduction ratios, respectively, between the motor generators and their respectively associated drive wheel units, and thus have characteristics, respectively, in efficiency with respect to torque and vehicular speed, that exhibit high efficiency in mutually different output ranges, respectively. When a mileage oriented mode is selected as a traveling mode, an ECU determines how a drive torque should be allocated between the motor generators, as based on the motors' required drive torque and vehicular speed and on each motor generator's characteristic in efficiency, to maximize the motor generators' total efficiency.
