摘要

Controller and weight-related physical quantity estimating device according to the invention, the braking force adjusting device for changing the relationship between the braking force of the rear wheel braking force of the front wheel as a function of the position of the displacement member which is displaced according to the support load of the rear wheel it is applied to a vehicle equipped with a. Estimates the support load of the rear wheel based on the braking force of the front and rear wheels, the fore-and-aft position of the center of gravity of the vehicle, the support load of the front wheel, the weight-related physical quantity estimation apparatus, a vehicle at least one of the total weight of the vehicle further I is estimated as the physical quantity related to the weight. The controller is changed based on the braking force of the front wheels and the rear wheels a value affected by the physical quantity related to the weight of the vehicle is a value to be used for control of the vehicle.
