Abstract: A control device for a heater that is installed in at least a portion of a member constituting a part of an outer surface of a vehicle and that melts snow of the member by generating heat through energization, the portion through which a radio wave of a radar installed in the vehicle is transmitted, includes: a dirt determination value calculation unit that calculates a dirt determination value for determining whether dirt adheres to an outer surface of the portion of the member based on a reception level of a radio wave received by the radar; and a heater control unit that executes heating control to energize the heater when an outside air temperature is in a predetermined low temperature range and the dirt determination value is equal to or larger than a predetermined threshold value.

Abstract: A support determination unit prohibits a driving support ECU from performing a driving support control in the situation where an axis tilt error has not been not confirmed yet, when an axis tilt state detection unit detects an axis tilt state of a radar. The support determination unit cancels prohibiting the driving support ECU from performing the driving support control, when the radar axis tilt state has disappeared before a predetermined time period elapses, the predetermined time period being a time period within which a cause for a temporary axis tilt state is expected to be removed.

Abstract: An obstruction detecting device includes: a main body disposed on a rear side, in a vehicle front-rear direction, of an emblem mounting portion of a front grille of a vehicle; and a connection-wire connector disposed on a back surface of the main body which faces rearward in the vehicle front-rear direction, so that its short direction is toward the rear side in the vehicle front-rear direction.
