Abstract: A vehicle control device assists in checking a rear side of an own vehicle. The vehicle control device includes a position estimation unit, an SN index calculation unit, a lane determination unit, and an alarm determination unit. The position estimation unit estimates a lateral position of an other vehicle based on a reflected wave of a radar wave. The SN index calculation unit calculates, based on the reflected wave, an SN index indicating a relationship between level of a noise and level of a signal. In response to determining a lane in which the other vehicle is traveling based on information on the lateral position of the other vehicle, the lane determination unit performs determination on the lane based on the SN index. The alarm determination unit determines whether a condition for issuing an alarm about the other vehicle is satisfied based on a result of determination of the lane.
