A deceleration factor estimation apparatus (1) estimating a deceleration factor of a vehicle (2) includes: a driving force acquisition unit (62) that obtains a driving force of the vehicle (2); a speed acquisition unit (60) that obtains a speed of the vehicle (2); an acceleration acquisition unit (61) that obtains an acceleration of the vehicle (2); and a deceleration factor estimation unit (63, 64, 65, 66) that estimates a plurality of deceleration factors on the basis of a relationship between the obtained driving force, speed, and acceleration, wherein the deceleration factor estimation unit (63, 64, 65, 66) switches the deceleration factor to be estimated on the basis of a travel condition of the vehicle (2). |
