1. A door handle sensor system for mounting in a vehicle, the door handle sensor system comprising:
a door handle device attached to a door of the vehicle; and
a control device configured to control an unlatched state of the door,
wherein the door handle device includes:
an inner case provided inside an outer case provided outside the vehicle;
an electrostatic sensor configured to detect a user coming close to, or in contact with, the outer case or the inner case; and
a pressure sensor configured to detect an operating force applied to the outer case or the inner case,
wherein the control device includes a determining part configured to determine whether a position of an operation by the user is in a first end section, a second end section, or a center section of the outer case and the inner case, the center section being located between the first end section and the second end section,
wherein the control device controls the unlatched state of the door based on a result of determination by the determining part and a value detected by the pressure sensor,
wherein the electrostatic sensor includes:
a first electrode including:
a plurality of first electrode parts arranged at spaced intervals in a first direction, the first direction extending between the first end section and the second end section; and
a first connecting part connecting between the plurality of first electrode parts on a first side in a second direction, the second direction being orthogonal to the first direction in plan view; and
a second electrode including:
a plurality of second electrode parts arranged alternately with the plurality of first electrode parts in the first direction; and
a second connecting part connecting between the plurality of second connecting parts on a second side in the second direction in plan view,
wherein the plurality of first electrode parts are provided only in the first end section and the center section,
wherein the plurality of second electrode parts are provided only in the second end section and the center section, and
wherein one of the plurality of second electrode parts is provided between two adjacent first electrode parts of the plurality of first electrode parts, and one of the plurality of first electrode parts is provided between two adjacent second electrode parts of the plurality of second electrode parts.
