Abstract: A vehicle driving device is driven by a power unit. A three-phase motor includes a first stator winding and a second stator winding. The first stator winding is connected in parallel to the second stator winding, and the first stator winding and the second stator winding are synchronized with each other. A first current sensor is coupled to the first stator winding for measuring a first-phase current. A second current sensor is coupled to the first stator winding for measuring a second-phase current. A third-phase current of the first stator winding is generated according to a calculating procedure of the first-phase current and the second-phase current. A duty cycle between a first power module and a second power module is controlled according to a feedback compensation of the first-phase current, the second-phase current and the third-phase current.

Abstract: A power detecting device includes a vehicle driving system, a battery detecting module and a controlling module. A first stator winding and a second stator winding are synchronized and connected in parallel with each other. A first end of a first current sensor is coupled to a first-phase winding end of the first stator winding for measuring a first-phase current. A first end of a second current sensor is coupled to a second-phase winding end of the first stator winding for measuring a second-phase current. The battery detecting module is coupled to a first power supply for measuring a current signal and a voltage signal. A controller generates a first power according to the current signal and the voltage signal and generates a second power according to a plurality of data from a database. The controller compares the first power with the second power to generate a detecting result.
