1. An obstacle detection device for a vehicle, comprising: a first measuring portion that determines a distance between the vehicle and an object in a vicinity of the vehicle; a second measuring portion that determines a distance between the vehicle and the object in the vicinity of the vehicle and has a different characteristic than the first measuring portion; and a controller that determines that the object is an obstacle when: the distance between the vehicle and the object determined by the first measuring portion and the distance between the vehicle and the object determined by the second measuring portion with the same timing used by the first measuring portion are consistent, and at least one of a displacement amount of the distance, a displacement amount of a relative velocity and a displacement amount of a relative acceleration at a predetermined interval of time from the vehicle to the object determined by the first measuring portion and a corresponding at least one of a displacement amount of the distance, a displacement amount of the relative velocity and a displacement of the relative acceleration from the vehicle to the object determined by the second measuring portion with the same timing used by the first measuring portion are consistent.
