Abstract:

Under extreme scenarios such as emergency obstacle avoidance or sharp turns, vehicles may experience yaw instability. Distributed corner module vehicles, equipped with independent four-wheel drive (4WID) and independent four-wheel steering (4WIS), offer high mobility advantages. However, the elimination of physical constraints between wheels increases the risk of yaw instability under extreme conditions. To enhance the yaw stability of corner module vehicles in such scenarios, in this paper a constraint-based yaw stability control strategy is proposed. An adaptive robust direct yaw moment control (ARC) driven by embedded equality constraints is designed, along with a longitudinal speed control mechanism. Additionally, an active rear steering (ARS) control strategy satisfying the steady-state cornering equality constraint is developed. By integrating a four-wheel torque optimization strategy, the proposed ARC+ARS cooperative control mechanism effectively improves the yaw stability of corner module vehicles under extreme conditions. The co-simulation results show that in a high-speed, high-adhesion double lane change scenario, the proposed control strategy reduces the root mean square (RMS) of yaw rate error and centroid sideslip angle by at least 53.1% and 15.3%, respectively. In a medium-speed, low-adhesion scenario, the reduction reaches at least 77.5% and 15.2%, respectively, with strong robustness in dealing with the systematic uncertainties and external disturbances.
