Abstract: A vehicular input apparatus includes a gesture sensor, an external device controller, and an output stop unit. The gesture sensor detects a gesture that is a non-contact gesture. The external device controller outputs an operation signal corresponding to the gesture detected by the gesture sensor to a first external device. When the gesture sensor detects the gesture, the output stop unit causes the external device controller to stop outputting the operation signal in response to a detection signal from at least one of a contact sensor and a proximity sensor for manipulating a second external device. The external device controller outputs the operation signal to the first external device after a second predetermined period of time.

Abstract: The electrostatic detection sensor has a first electrode, a second electrode, and a third electrode. A controller connects the first electrode and the second electrode, and applies a first drive voltage thereto to obtain a first intensity. The controller applies a second drive voltage to the first electrode while keeping the second electrode and the third electrode at a ground potential to obtain a second intensity. The controller applies a third drive voltage to the third electrode while grounding the first electrode to the ground potential and keeping the second electrode open to obtain a third intensity. Then, the controller determines whether an object is approaching based on first, second, and third computed values which are computed temporal changes in the first, second, and third intensities, respectively.

Abstract: A sensor body of an electrostatic detection sensor includes a first electrode and a second electrode surrounding the first electrode. A controller is configured to obtain a first sensed intensity of the sensor body while where the first electrode is connected to the second electrode. The controller is configured to obtain a second sensed intensity of the first electrode while the second electrode is grounded. The controller is configured to obtain a third sensed intensity of the second electrode while the first electrode is grounded. The controller is configured to determine whether an object approaches the sensor body or not based on first to third calculation values obtained by calculating the respective changes of the first to third sensed intensities with respect to time.
