Abstract
The present invention achieves a technique that not only makes it possible to reduce sensor-related cost but also makes it possible to estimate a ground contact load of a vehicle with sufficiently high accuracy. A ground contact load estimation device () causes an acquisition section to acquire a physical quantity related to a vehicle, causes a reference inertia load calculation section () to calculate a reference inertia load with use of the physical quantity, uses the physical quantity to cause a correction value calculation section () to calculate an inertia load correction value, and causes an inertia load estimation section () to estimate an inertia load by adding the inertia load correction value to the reference inertia load.
