Vehicle stability control system
First Claim
1. A vehicle stability control system comprising:
- a basic request driving force computing unit for computing a physical quantity corresponding to a basic request driving force so as to generate the basic request driving force requested by a driver for a driving wheel provided for a vehicle;
a front and rear wheel load computing unit for detecting a ground load applied to each of front wheels and rear wheels in the vehicle;
a virtual turning radius estimating unit for estimating a virtual turning radius in the vehicle;
a target value computing unit for computing a target value of a stability factor based on the results of computations in the front and rear wheel load computing unit and the virtual turning radius estimating unit; and
a vibration damping correction controlling unit for correcting a physical quantity corresponding to the basic request driving force computed by the basic request driving force computing unit so as to follow the target value computed by the target value computing unit, wherein a driving force in accordance with the corrected physical quantity corrected by the vibration damping correction controlling unit is generated for the driving wheel.

Abstract
A vehicle stability control system includes a basic request driving force computing unit, a front and rear wheel load computing unit, a virtual turning radius estimating unit, a target value computing unit, and a vibration damping correction controlling unit. The basic request driving force computing unit computes a physical quantity so as to generate the basic request driving force requested by a driver. The front and rear wheel load computing unit detect a load applied to the wheels. The virtual turning radius estimating unit estimates a virtual turning radius. The target value computing unit computes a target value of a stability factor. The vibration damping correction controlling unit corrects the physical quantity so as to follow the target value. The system generates the driving force for the driving wheel.
