Title:
An object sensing device and an object detection system
Document Type and Number:
Japanese Patent JP6146228
Kind Code:
B2
Abstract:
An object detection apparatus mounted to a vehicle includes a transmitter, a receiver, a filter, a threshold calculator, and an object determinator. The transmitter transmits a probe wave in pulse form. The receiver receives a reflected wave of the probe wave. The filter passes, among the received reflected wave, only frequencies that are at least smaller than a pulse frequency of the probe wave. Based on an output of the filter, the threshold calculator calculates an objection determination threshold for determining presence and absence of an object. The object determinator determines the presence and absence of the object by using the objection determination threshold calculated by the threshold calculator.
