RAINFALL DIRECTION ESTIMATING DEVICE FOR VEHICLE, AND DRIVING ASSISTANCE DEVICE FOR VEHICLE

摘要

PPROBLEM TO BE SOLVED: To provide a rainfall direction estimating device for a vehicle capable of estimating a rainfall direction while avoiding increase of burden of a facility. PSOLUTION: The rainfall direction estimating device for the vehicle is provided with: a plurality of electrostatic capacity type touch sensors for outputting contact or approaching of an object as variation of a voltage, i.e., a plurality of electrostatic capacity type touch sensors installed on a plurality of door handles in the vehicle; and a rainfall direction estimating means for estimating the rainfall direction based on the voltage variation amount in the plurality of electrostatic capacity type touch sensors.
