Abstract: In a door handle sensor system, a door handle device includes an electrostatic sensor to detect the user with respect to a door handle, and a pressure sensor to detect the operating force applied to the door handle. A control device determines whether the position of an operation is in a first end section, a second end section, or a center section of the door handle, and controls an unlatched state based on the determination result and the value detected by the pressure sensor. The electrostatic sensor includes a first electrode including multiple first electrode parts and a second electrode including multiple second electrode parts arranged alternately with the first electrode parts. The first electrode part other than the endmost first electrode part in the first direction and the second electrode part other than the endmost second electrode part in the first direction are arranged in the center section.
