Title:
VEHICLE SENSOR DEVICE, AND VEHICLE LAMP FITTING
Document Type and Number:
WIPO Patent Application WO/2022/070748
Kind Code:
A1
Abstract:
A vehicle sensor device (1) is provided with: an outer cover (12); a sensor unit (20) which is disposed further toward the inside of a vehicle (VE) than the outer cover (12), sends and receives prescribed electromagnetic waves that are transmitted through the outer cover (12), and outputs a signal relating to electromagnetic waves which enter the inside of the outer cover (12); and a heat generating member which, by means of the conduction of electricity, heats a transmission region (AR) of the outer cover (12) through which the electromagnetic waves sent from the sensor unit are transmitted. The heat generating member is attached to the outer cover (12) in such a way that the inside of the transmission region (AR) is sparser than the outside of the transmission region (AR).
