A controller controls an on-vehicle device having an operating member operated by a driver to receive a driver's operating force and an assisting mechanism giving an assisting force to the operating member. This mechanism is powered by an on-vehicle battery. The controller detects forces applied to the device and calculates a control amount giving the assisting force to the device based on results detected by the force detector. The control amount is calculated every type of the applied forces whose frequency bands are at least partly different from each other.
