Tracking detection system of electrical servomotors

Abstract

The invention relates to a tracking detection system of electrical servomotors with incremental position detection in particular for servomotors in motor vehicles. To determine the position, said tracking detection system is provided with a microcontroller with an autoalarm device. Said microcontroller can be moved from run mode (B1) to sleep mode (B0) to reduce the average current intake, and after a predetermined period of time (e.g. 1 mm) can be automatically moved back to run mode (B1). Said microcontroller samples the position signals (HS) of position transmitter when it is in run mode (B1) at particular sampling points (11, 12), and is move between the required sampling points for a particular, calculated period of time in sleep mode (B0). The particular, calculated period of time is calculated from a detected edge change of the position signal.
