Vehicle stability control system
First Claim
1. A vehicle stability control system comprising:
- a base required driving force calculation unit that calculates a physical quantity corresponding to a base required driving force desired by a driver to generate the base required driving force at a driving wheel of a vehicle;
an estimated driving force estimation unit that obtains a physical quantity corresponding to an estimated driving force that is estimated as being generated in the vehicle; and
a required driving force correction unit that obtains a corrected required driving force in such a way that a pitching vibration possibly occurring in the vehicle when the estimated driving force is generated is obtained on the basis of the physical quantity corresponding to the estimated driving force, a correction to suppress the pitching vibration is obtained, and the physical quantity corresponding to the base required driving force calculated by the base required driving force calculation unit is corrected on the basis of the correction, wherein the corrected required driving force obtained by the required driving force correction unit is generated at the driving wheel.

Abstract
A vehicle stability control system includes a base required driving force calculation unit, an estimated driving force estimation unit, and a required driving force correction unit. The base required driving force calculation unit calculates a physical quantity to generate the base required driving force at a driving wheel. The estimated driving force estimation unit estimates a driving force as being generated in the vehicle. The required driving force correction unit obtains a correction to suppress a potential pitching vibration in the vehicle. The physical quantity calculated by the base required driving force calculation unit is corrected on the basis of the correction. The corrected required driving force obtained by the required driving force correction unit is generated at the driving wheel.
