Abstract: A control apparatus of a door for a vehicle includes a first electrode corresponding to an electrostatic sensor electrode including a first detection surface, and a second electrode corresponding to an electrostatic sensor electrode including a second detection surface including an overlapping region which overlaps with the first detection surface and a non-overlapping region. The control apparatus includes a control portion configured to switch between a first detection state in which the first electrode is driven and an electric potential of the second electrode is at a float, and a second detection state in which the second electrode is driven and an electric potential of the first electrode is in a grounded state, and configured to identify an action instruction to the door for the vehicle on the basis of an electrostatic capacitance value measured at the first electrode and the second electrode.

Abstract: A capacitance sensor detects proximity of a detection object based on changes in capacitances between the detection object and a first detection electrode and between the detection object and a second detection electrode. The capacitance sensor includes: a capacitor applied with a first potential; a first switch provided over terminals of the capacitor; a second switch connected to the capacitor; a third switch connected to the second switch and the first detection electrode, and applied with a second potential; a fourth switch connected to the capacitor; a fifth switch connectable to the second detection electrode and connected to the fourth switch, and applied with the second potential; and a determination unit determining a failure of the first detection electrode based on a potential difference between a potential of the terminal of the capacitor and a reference potential.
