A bump detector for detecting a bump on a road surface where a vehicle travels, includes a processor, which acquires a motor torque of a motor connected to a tire, a tire angular acceleration, a motor angular acceleration, and speed information of the vehicle, calculates a force in a horizontal direction acting on the tire when the tire rides on the bump, and estimates a bump height in accordance with the force in the horizontal direction on a basis of bump information, in which peaks of a tire front-rear force in the horizontal direction before and after the tire rides on the bump on the road surface calculated in advance for each vehicle speed are associated with bump heights, and the speed information.
