For the configuration of Four Wheel Independent Drive Electric Vehicles (4WIDEV), an adaptive cruise control system integrating Active Front Steering (AFS) and Direct Yaw-moment Control (DYC) has been developed. This system is based on a dual-layer control architecture. The upper-level controller employs a Model Predictive Control (MPC) strategy to precisely track the vehicle's desired longitudinal force and additional yaw moment. The lower-level controller utilizes the control redundancy of AFS and DYC to optimize the calculation of the additional steering angle for the front wheels and the torque distribution for all four wheels, enhancing the vehicle's stability and economy. Simulation results indicate that, compared to traditional average torque distribution strategies, this integrated control strategy can achieve up to 13.02% energy savings while ensuring vehicle stability. This research provides new insights into enhancing the comprehensive performance of 4WIDEV.
