DOOR HANDLE DEVICE

摘要

A door handle device capable of operating a door opening/closing mechanism of a vehicle is disclosed. The door handle device includes a support member 21, a door handle 10, a circuit substrate 30, a lock detection electrode 31, a capacitance sensor 41, and an auxiliary electrode 35. The circuit substrate 30 is arranged in the door handle 10 and includes a ground electrode GNDB. The lock detection electrode 31 is mounted on the circuit substrate 30 and capacitance-coupled to an outer panel 20 of the door. The capacitance sensor 41 is connected to the lock detection electrode 31 and detects the issuance of a door lock command based on a change in a first capacitance C PANEL between the outer panel 20 and the lock detection electrode 31. The auxiliary electrode 35 is capacitance-coupled to the ground electrode GNDB to form a second capacitance C BOARD connected in parallel to the first capacitance C PANEL between the auxiliary electrode and the ground electrode GNDB.
