HUMAN BODY DETECTOR FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a human body detector for vehicles realizing good detection performance with a simple structure even under poor environment, without requiring a large space.

SOLUTION: In a door handle 1 arranged outside a door 10 for a vehicle, a sensor electrode 5 of which the capacitance varies with approach of a human body is provided. A judgment circuit judging the approach of a human body based on the variation of the capacitance of the sensor electrode 5 is provided. An auxiliary electrode 6 of a float state with a capacitance coupled to the sensor electrode 5 is provided in the door handle 1 by locating in the vicinity of the sensor electrode 5.
