PROBLEM TO BE SOLVED: To prevent a malfunction from being caused by an operation erroneously detected due to vibrations of an own vehicle while suppressing an increase in cost in an in-vehicle device provided with a plurality of operation parts for detecting an operation by a distortion detection element.SOLUTION: Two touch pads attached to a steering to detect a touch operation by a distortion detection element are connected to a navigation system, and operations of the navigation system or the like using the touch pads are possible. A control part of the navigation system determines that operation information is erroneously detected because operation positions shown by the operation information are close to each other in a case that the operation information are received from each touch pad at the same period of time, and due to vibrations of an own vehicle in a case that operation forces shown by the operation information are at the same level, and invalidates the operation information (S225). |
