Vehicle yaw reduction based upon right and left vehicle wheel acceleration differences and use of brake control

摘要

The yaw moment reducing device comprises wheel speed sensors for detecting the speeds of the right and left wheels, an acceleration calculation device for calculating accelerations of the right and left wheels based on the speed of the right and left wheels, a substraction device for subtracting the difference in accelerations between the right and left wheels, a braking control device for controlling the braking force based on the difference of the accelerations, and a brake pressure modulating device for modulating the brake pressure which is supplied to each wheel. The wheel speeds of each wheel are detected by the wheel speed sensors. The acceleration calculation device calculates the accelerations of each wheel while the substraction device provides the difference in accelerations between the right and left wheels. The yaw moment is in response to the difference of the acceleration between the right and left wheels. In other words, the yaw moment can be presumed by the difference of the acceleration between the right and left wheels. The brake pressure modulating device modulates the brake pressure which is supplied to each wheel based on the calculation result of the braking control devices. Thus, the yaw moment can be controlled.
