Title:
INTRUSION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/101141
Kind Code:
A1
Abstract:
Provided is an intrusion detection device that detects an intrusion of a person into a vehicle. The intrusion detection device includes a transmission unit, a reception unit, a mixing unit, and a determination unit. The transmission unit transmits an ultrasonic wave of an oscillation signal to the inside of the vehicle, and the reception unit receives the ultrasonic wave propagating in the vehicle and converts the received wave into an electric signal. The mixing unit mixes the electric signal output from the reception unit and the oscillation signal to generate a Doppler signal. The determination unit determines the presence or absence of a person in the vehicle on the basis of the Doppler signal. When the magnitude of the Doppler signal exceeds a predetermined threshold, the determination unit switches the sensitivity for the presence or absence of a person in the vehicle from a basic sensitivity mode to a high sensitivity mode in which the detection area is set wider.
