ON-BOARD DEVICE

摘要

The on-board device according to the present invention, which outputs a control signal to a cleaning control unit that controls a plurality of accretion removal units, each having a method for removing accretion, attached to the imaging lens of an on-board camera, is equipped with an accretion detecting unit that detects accretion attached to the imaging lens from an imaged image output from the on-board camera when an input vehicular speed is greater than or equal to a predetermined vehicular speed, a selecting unit that selects an accretion removal unit of a first method from the plurality of accretion removal units each having a method for removing accretion, and a removal determining unit that uses the imaged image to determine whether accretion has been removed from the imaging lens by the removal movement from the accretion removal unit of the first method selected by the selecting unit. When the removal determining unit determines that accretion has not been removed from the imaging lens, the selecting unit selects an accretion removal unit of a second method that is different to the accretion removal unit of the first method, on the basis of the number of times that the accretion removal unit of the first method was used to perform a removal movement.
