Abstract
The vehicle speed calculation device includes a target category determination unit, a vehicle speed calculation unit, a positional relationship calculation unit, and a vehicle speed correction unit. The positional relationship calculation unit calculates the positional relationship between the vehicle and the fixed target in a height direction. The vehicle speed correction unit increases, when the target is an object on a road, degree of correction of the vehicle speed using the relative vehicle speed compared to when the target is an upper object.
