PROCEDIMENTO E DISPOSITIVO PER IL RILEVAMENTO DI ALMENO UN OGGETTO IN MOVIMENTO NELL'AMBIENTE DI UN VEICOLO

摘要

The method involves transmitting and receiving reflected acoustic signals (45) of object (20) by ultrasonic sensor (30) for determining position and movement of object. The ultrasonic sensor is switched in transmission and receiving mode based on velocity of vehicle and determined vehicle noise level. The acoustic signals are transmitted and received in transmission and receiving mode and acoustic signals are received and not transmitted in receive mode. The position and movement of moving object is evaluated based on received noise signals (46). Independent claims are included for the following: (1) an device for detecting moving object in vehicle environment; (2) a dead angle monitoring system; and (3) a vehicle assistance system.
