An operation panel includes a touch position sensor configured to output an electrical signal corresponding to a contact area between a finger of a user and a switch and a controller to which an electrical signal is input from the touch position sensor. The controller is configured to: determine that the finger of the user and the touch position sensor are in contact with each other when the calculation value calculated based on the electrical signal input from the touch position sensor exceeds the preset first threshold value, and set, based on the calculation value, the second threshold value larger than the first threshold value in accordance with a magnitude of the calculation value; and determine that the touch position sensor is in the operation state of being operated when the calculation value exceeds the second threshold value.

Operation panel

An operation panel provided on a vehicle is provided with: a panel member exposed to an interior of a vehicle cabin of the vehicle; an operation part provided on the panel member; and a load sensor provided so as to face a back surface of the panel member, the a load sensor being configured to detect that the operation part has been operated based on a load caused by a displacement of the panel member, wherein the load sensor is provided at a position where the displacement of the panel member is greater than a displaced amount of the operation part when the operation part is operated, the panel member has a projected portion projecting out from the back surface such that a tip end portion faces the load sensor, and the projected portion is formed of divided projected portions, the divided projected portions being provided by being divided into a plurality of parts.

An ON/OFF detection device is configured to detect ON/OFF of an input unit using a load sensor, and includes a threshold setting unit, a comparison unit, and an ON/OFF determination unit. The threshold setting unit is configured to set a threshold value with respect to a previous detection value of the load sensor. The comparison unit is configured to compare the threshold value and a current detection value. The ON/OFF determination unit is configured to determine ON/OFF of the input unit based on a comparison result. When a previous determination result of the ON/OFF determination unit is ON, the threshold setting unit is configured to set the threshold value to be lower than the previous detection value. When the previous determination result of the ON/OFF determination unit is OFF, the threshold setting unit is configured to set the threshold value to be higher than the previous detection value.
