“…The individual control algorithm of the ESC-4WD-ARS system has been presented in previous studies. 19,20,23 To ensure stability from the uncertainty of correlation, the front and rear torque distribution ratios of 4WD and ARS were constrained in the range from 3:7 to 7:3. Moreover, the control activation threshold of ESC was set to be higher than those of 4WD and ARS to minimize unwilling braking.…”

This paper proposes a coordinated control algorithm of the differential braking, the front and rear traction torques and the active roll moment to enhance the limit-handling performance. The coordinated algorithm is designed to maximize the driving velocity while keeping the vehicle in a lane. First, the analysis of the cornering dynamics is described to consider the non-linear characteristics of the tyres during acceleration or deceleration. The target vehicle motions are determined on the basis of the driver's intention and the current states of the vehicle. An optimization-based control allocation strategy is utilized to distribute the actuator control inputs optimally by considering the tyre and vehicle limitations. Closed-loop simulations of a driver-vehicle-controller system were conducted to investigate the performance of the proposed control algorithm. The performance of the coordinated algorithm was compared with those of the individual coordination algorithms. The simulation results show that the proposed integrated chassis controller improves the performance in high-speed cornering with respect to the driving speed without losing stability compared with simple coordination chassis control systems.

“…[19], [25]- [27]. For example the authors of [26] used an Integrated Chassis Control (ICC) strategy to improve cornering performance in high speed by combining the ESC, the 4-Wheel Drive (4WD) and the Active Roll Control (ARC) systems. The control architecture is composed of thee parts: a supervisory controller that determines the target vehicle motions, the upper-level controller that calculates the target forces and moment and the lower-level controller that optimally distributes the actuator inputs.…”

Most of the chassis systems are developed by automotive suppliers to improve a specific vehicle performance. Drivers, and consequently vehicle manufacturers, are more concerned by the overall behaviour of the Vehicle. Many coordination architectures have been proposed in the literature in order to integrate different chassis systems in a single vehicle. In this paper, these architectures are compared and discussed. Two major classes are proposed: Downstream and Upstream Coordination. The purpose of this classification is to help car manufacturers and suppliers standardize an Integrated Vehicle Dynamics Control architecture for faster and more flexible designs.

“…According to different situation, the management system could automatically implement comfort-orientated or safety-orientated coordination strategy and shut-down strategy in case of fault. 17 In the paper by Heo et al, 18 the integrated chassis control (ICC) algorithm has been designed to maximize driving velocity in cornering situation by optimal coordination among three individual chassis control modules: 4WD, ESC and ARS. A closed-loop driver-vehicle-controller simulation showed the ICC increased maximum lateral acceleration and reduced the lap time for vehicle.…”

In order to improve the performance of ground vehicle equipped with the active front-wheel steering and active stabilizer bar, the coordination for the two systems has been researched. A layered functional framework is proposed: the upper controller coordinates yaw motion with a designed Fuzzy proportional–integral–derivative controller algorithm correcting the outputs of active front-wheel steering and active stabilizer bar; for the middle subsystems, an ideal steering ratio is designed with the Sigmoid function to achieve the active steering, and a sliding mode algorithm is designed to reduce the roll angle; the bottom actuators achieve the control target from the middle layer. In addition, the upper layer has a rebuilt fuzzy rule-based fault-tolerant mechanism that handles the failure of stabilizer bar actuators to guarantee the stability of roll and yaw motion. Finally, the simulation and rapid-control-prototype test for step steering show that the designed algorithm can ensure roll and yaw performance. In consideration of the accidental failure of active stabilizer bar actuators, by actively adjusting the coordinated rules, the system could overcome the contradiction of coupling control and still maintain yaw and roll stability, which improves the active safety.
