Abstract:
1. A human body detecting device for a vehicle comprising: a sensor electrode provided in a door handle arranged on outside of a vehicle door, the sensor electrode changing an electrostatic capacitance in response to an approach of a human body, a determining circuit signally connected to the sensor electrode for determining an approach of a human body based on the change of the electrostatic capacitance of the sensor electrode, and an auxiliary electrode, that is coupled capacitance-wise with the sensor electrode, provided within the door handle, wherein the auxiliary electrode is provided to a core member of the door handle, wherein the core member has a generally H-shaped cross section with two generally parallel leg portions and a cross member connecting the two leg portions, and wherein the sensor electrode and the auxiliary electrode are located on a side of the cross member facing the door outer panel.
