Title:
SENSOR SYSTEM AND VEHICLE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2023/106137
Kind Code:
A1
Abstract:
Provided are: a sensor system which is capable of reducing power consumption without changing the detection accuracy of a prescribed displacement exhibited by a measurement target, even when using a plurality of first and second sensors; and a vehicle equipped with the same. This sensor system (1) is equipped with a first sensor (2), a second sensor (3) and a signal processing device (4). The first sensor (2) emits an electromagnetic wave at a measurement target (5), and detects a prescribed displacement which is exhibited by the measurement target (5) on the basis of a reflected wave. The second sensor (3) detects vibrations which occur in or are transmitted to the measurement target (5) and/or the first sensor (2), or detects a prescribed displacement exhibited by the measurement target (5). On the basis of the detected data, an operation sensor determination unit (4a) removes or attenuates noise vibrations which overlap the prescribed displacement, and selects an operation sensor which must be switched to the minimum operation level. A sensor power supply management unit (4b) provides a supply of power only to the sensor which was selected to function as the operation sensor.
