Abstract
A human body detecting device for a vehicle includes a sensor electrode provided in a door handle arranged on outside of a vehicle door, the sensor electrode changing the electrostatic capacitance in response to an approach of human body and a determining circuit for judging whether a human body approaches or not based on the change of the electrostatic capacitance of the sensor electrode. The human body detecting device further includes an auxiliary electrode coupled capacitance-wise with the sensor electrode.

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.
A human body detecting device for a vehicle comprising:
- a door handle arranged outside of a vehicle door,
- a conductive sensor electrode provided inside of the door handle, and
- a flat plate auxiliary electrode disposed between the sensor electrode and the vehicle door and positioned inside of the door handle, wherein the flat plate auxiliary electrode is coupled capacitance-wise with the sensor electrode and wherein a human body is detected by a change of an electrostatic capacitance between the sensor electrode and the vehicle door,
- wherein the auxiliary electrode is provided to a core member of the door handle, and
- 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.
