1. A vehicle compelling force detection apparatus that is installable in a vehicle and capable of detecting a compelling force due to a wind disturbance, the vehicle compelling force detection apparatus comprising:
one or more processors; and
one or more memories coupled to the one or more processors so as to be able to communicate with the one or more processors,
wherein the one or more processors are configured to:
obtain, from a first sensor, an unsprung mass signal related to a road surface disturbance force received from a road surface on which the vehicle drives via a wheel of the vehicle, and store the road surface disturbance force in the one or more memories;
obtain, from a second sensor, a sprung mass signal related to a body disturbance force applied to the vehicle, and store the body disturbance force in the one or more memories;
compare a magnitude of the unsprung mass signal and a magnitude of the sprung mass signal; and
in response to the magnitude of the unsprung mass signal being less than the magnitude of the sprung mass signal, detect the compelling force due to the wind disturbance to which the vehicle is subjected, based on the body disturbance force applied to the vehicle and the road surface disturbance force, which are stored in the one or more memories, the compelling force being detected by calculating a degree of phase alignment between the body disturbance force applied to the vehicle and the road surface disturbance force,
wherein the first sensor is disposed below, in a direction of gravity, and the second sensor is disposed above, in the direction of gravity, a damper such that the first sensor and the second sensor are arranged for the wheel,
wherein the damper supports the wheel in the direction of gravity.
