Abstract
A spin suppress control device of a vehicle estimates a spin quantity of the vehicle to represent a liability of its spinning, and selectively and variably brakes each of the wheels according to the spin quantity so as to decelerate the vehicle within a range of generating no substantial yaw moment in the vehicle when the spin quantity exceeds a first threshold value therefor, and provides the vehicle with an anti-spin moment when the spin quantity exceeds a second threshold value therefor greater than the first threshold value.
Claims6
A spin suppress control device of a vehicle having a vehicle body and wheels, comprising a means for estimating a spin quantity of the vehicle to represent a liability of a spinning thereof, and a means for selectively and variably braking each of said wheels according to said spin quantity, wherein the device actuates said braking means so as to decelerate the vehicle within a range of generating no substantial yaw moment in the vehicle by the actuation of said braking means when said spin quantity exceeds a first threshold value therefor, and to provide the vehicle with an anti-spin moment when said spin quantity exceeds a second threshold value therefor greater than said first threshold value.
