摘要

A side-slip velocity estimation module (62) for a vehicle stability enhancement control system (12) includes a side-slip acceleration estimation module (78) that determines an estimated side-slip acceleration of a vehicle. A limited-frequency integrator (80) integrates the estimated side-slip acceleration to determine an estimated side-slip velocity of the vehicle. A reset logic module (82) clears an output of the limited-frequency integrator when a first condition occurs. The first condition is one of a straight-driving condition, a speed condition, and a sensor bias condition. The estimated side-slip velocity (72) is compared to a desired side-slip velocity (68) to produce a side-slip control signal (74). The side-slip control signal (74) is combined with a yaw rate control signal (70) to produce an actuator control signal (14). The actuator control signal is received by one of at least one brake actuator (16) and a rear-wheel steering actuator (24) to create a yaw moment to correct a dynamic behavior of the vehicle.
