When the zero-crossing of one of the output signals of magnetic sensors has been detected, a rotation angle computing device identifies a magnetic pole sensed by the first magnetic sensor based on the other two output signals. Subsequently, the rotation angle computing device identifies the magnetic pole sensed by the second magnetic sensor and the magnetic pole sensed by the third magnetic sensor based on the magnetic pole sensed by the first magnetic sensor. After that, the rotation angle computing device corrects the amplitude of the output signal of each magnetic sensor based on the identified magnetic poles respectively sensed by the magnetic sensors. Then, the rotation angle computing device computes the electric angle θe of the rotor based on the corrected output signals.

The invention relates to a method for the provision of a D.C. voltage, in particular for a motor vehicle which is supplied by a battery when at a standstill. The method is carried out by means of a microcontroller νC (40), an auxiliary supply (231; 232; 320, 331) and a seal-in circuit (26; 26') for maintaining the auxiliary supply in an active state. The method comprises the following steps: the auxiliary supply (231, 232; 320, 331) is activated by a closing criterion, which initiates the activation of the microcontroller νC (40), the latter in turn activating the seal-in circuit (26; 26'); the microcontroller νC (40) detects the presence of a disconnection command and after said detection the seal-in circuit (26; 26') is deactivated by the microcontroller νC (40) with a delay corresponding to predetermined criteria.
