Zusammenfassung: | The utility model discloses a circuit for identifying the travel of a vehicle door handle, which comprises a comparator, a fourth resistor (R4) arranged between the normal phase input end of the comparator and a Hall sensor, and a sixth resistor (R6) arranged between the output end of the comparator and the normal phase input end. According to the utility model, the resistors are respectively added at the normal phase input end and the output end of the comparator in the existing circuit to form the hysteresis comparator, and the influence on the comparator when clutters appear in the HALL signal is avoided through double thresholds, so that the MCU can completely and accurately identify the processed HALL signal; meanwhile, circuit improvement is simple, only two resistors need to be added on the basis of an existing circuit, other chips do not need to be added, cost is saved, and large-scale popularization is facilitated.
