“…The purpose of the desired yaw moment is to reduce the yaw rate error between the actual yaw rate and the target yaw rate determined in Section II. To calculate the desired yaw moment, using (3) and (4), the bicycle model can be re-written by eliminating the body side slip angle as follows [15]:…”

This paper propose a unified chassis control (UCC) strategy to improve agility, maneuverability and, vehicle lateral stability by the integration of active front steering (AFS) and electronic stability control (ESC). The proposed UCC system consists of a supervisor, a control algorithm, and a coordinator. The supervisor determines a target yaw rate and a target velocity. To achieve a target yaw rate and velocity, the control algorithm determines a desired yaw moment and a desired longitudinal force, respectively. The desired yaw moment and the desired longitudinal force can be generated by the coordination of the AFS and ESC systems. To consider a performance limit of the ESC system and tires, the coordination is designed using the optimal method. Closed loop simulations with a driver-vehicle-controller system were conducted to investigate the performance of the proposed control strategy using CarSim vehicle dynamics software and the UCC controller coded using Maltab/Simulink.

“…The sensitivity results were then used to optimize the steering system parameters that will help vehicles with the integration of individual modular chassis control systems in order to provide key advantages for vehicle power such as AFS (Adaptive Front-Lighting System), 4WD (4-Wheel Drive), ECS (electronic control suspension system). It seems to be a more efficient method to provide crucial benefits for vehicle dynamics such as agility, maneuverability or additional stability improvement [8][9][10][11].…”

Featured Application: Measurement and performance evaluation for vehicle.Abstract: A full-vehicle analysis model was constructed incorporating a SLA (Short Long Arm) strut front suspension system and a multi-link rear suspension system. CAE (Computer Aided Engineering) simulations were then performed to investigate the lateral acceleration, yaw rate, roll rate, and steering wheel angle of the vehicle during constant radius cornering tests. The validity of the simulation results was confirmed by comparing the computed value of the understeer coefficient (K us ) with the experimental value. The validated model was then used to investigate the steady-state cornering performance of the vehicle (i.e., the roll gradient and yaw rate gain) at various speeds. The transient response of the vehicle was then examined by means of simulated impulse steering tests. The simulation results were confirmed by comparing the calculated values of the phase lag, natural frequency, yaw rate gain rate, and damping ratio at various speeds with the experimental results. A final series of experiments was then performed to evaluate the relative effects of the cornering stiffness, initial toe-in angle, and initial camber angle on the steady-state and transient-state full-vehicle cornering handling performance. The results show that the handling performance can be improved by increasing the cornering stiffness and initial toe-in angle or reducing the initial camber angle.

“…A unified chassis control (UCC) strategy has been proposed for improving agility, manoeuvrability and lateral stability of a vehicle through integration of the active front steering (AFS) and ESC. 1 The proposed UCC system consists of a supervisor and a coordinator to integrate the active front steering-angle brake. In order to control the inputs optimally, the control modes are determined by the supervisor, and the Karush-Kuhn-Tucker condition is used to compute the optimized coordination of the tyre forces, by considering the tyre friction circle constraints.…”

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.
