  • Patent number: 10814704
    Abstract: An operation input determination device includes an operation input detector, a movement detector, and a sensor output correction unit. The operation input detector detects an operation input to an operation input unit, which is arranged on a vehicle surface, based on a sensor output of a capacitance sensor that changes when a detection subject moves toward and away from the operation input unit. The movement detector detects movement of a vehicle. The sensor output correction unit executes calibration on the capacitance sensor when movement of the vehicle is detected.

  • Patent number: 10436610
    Abstract: An operation input detection device includes an operation input detection unit, a change amount accumulation unit, a section variation amount calculating unit, and a noise determination unit. The operation input detection unit detects an operation input on an operation input unit based on a sensor output of a capacitance sensor. The change amount accumulation unit accumulates a change amount of the sensor output in a determination section. The change amount of the sensor output is a difference of a detection value of the sensor output detected as each sampling timing from a previous value of the sensor output. The section variation amount calculating unit calculates a section variation amount of the sensor output.
