An angular position detection device in a hybrid vehicle includes a crankshaft sensor for detecting an absolute internal combustion engine angular position with respect to a defined position mark, an electric machine, a rotor position sensor for detecting a relative electric machine angular position based on a reference point, in particular a reference pole comprising a plurality of identical rotor poles, and an electronic control unit. The control unit is configured such that the absolute internal combustion engine angular position and the relative electric machine angular position are detected when the internal combustion engine is stationary and the electric machine is stationary, and a mechanical angular reference of the internal combustion engine with respect to the electric machine is determined, on the basis of these angular positions, as an angle difference between the position mark and an initial reference point.
