The invention relates to a method for operating a drive device (2) of a motor vehicle (1), comprising at least one electric machine (6) that includes a phase angle transducer (11), and an output shaft that can be operatively connected to the electric machine (6). According to the invention, a diagnostic operating mode of the drive device (2) is activated when the return value of the phase angle transducer (11) is constant, the operative connection between the electric machine (6) and the output shaft being interrupted in said diagnostic mode, whereupon the electric machine (6) is adjusted to a specific speed, and if the return value continues to be constant, it is concluded that the phase angle transducer (11) is in a first operating mode, but if the return value changes, it is concluded that the phase angle transducer (11) works properly. The invention further relates to a drive device (2) of a motor vehicle (1). |
