Abstract
It is predicted whether a spin amount is tending to diverge and a vehicle is tending to become unstable, or the spin amount is tending to converge and the vehicle is tending to become stable. When the convergent tendency is predicted, a correction to reduce the spin amount is performed. As a result, the performance of a braking force control can be made difficult when the spin amount is tending to converge. Thus, it is possible to prevent an anti-spin control from being performed when there is actually no need to perform the anti-spin control, such as when the vehicle posture is correcting.
Claims20
A vehicle behavior control device, comprising:
- a first calculation means for calculating a spin amount serving as an index of spin behavior of a vehicle;
- a control means for performing a braking force control of each wheel of the vehicle to prevent side skip in accordance with the spin amount;
- a second calculation means for calculating a cornering force corresponding amount of a front wheel of the vehicle;
- a determination means for determining that the vehicle is not spinning when the cornering force corresponding amount of the front wheel calculated by the second calculation means is within a determined range;
- and
- a correction means for correcting the spin amount based on a result of determination of the determination means.
