Title:
WEIGHT-RELATED PHYSICAL QUANTITY ESTIMATING SYSTEM AND CONTROL DEVICE FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2010/116542
Kind Code:
A1
Abstract:
Provided are a weight-related physical quantity estimating system and a control device, which are applied to a vehicle including a braking force changing device for changing the relations between the braking force of front wheels and the braking force of rear wheels in accordance with the position of a displacement member which moves in accordance with the supporting load of the rear wheels. On the basis of the braking forces of the front wheels and the rear wheels, the weight-related physical quantity estimating system estimates the supporting load of the rear wheels, and estimates at least one of the longitudinal position of the center of gravity of the vehicle, the supporting load of the front wheels and the total weight of the vehicle, as a physical quantity relating to the weight of the vehicle. Moreover, the control device changes the value to be used for controlling the vehicle, that is, the value to be influenced by the physical quantity relating to the vehicle weight, on the basis of the braking forces of the front wheels and the rear wheels.
