“…For instance, the safety-critical-oriented control strategies, including the stability control, tail swing drift control as well as electronic stability program, have always been the attention of automotive researchers 1 . Specifically, extreme driving including high velocity and the fierce steering angle is the main reason for the instability of the vehicle 2 . Therefore, many methods including active suspension (AS) 3 , 4 , electronic stability program (ESP) 5 , dynamic cruise control 6 , active steering control (ASC) 7 , or the use of stabilizer bars 8 have been proposed to address the above problems.…”

Vehicular safety is of considerable significance to the intelligent development of hybrid vehicles. However, the real-time stability control or reasonable torque distribution under the extreme road conditions remain a huge challenge due to the multiple uncertain parameters and difficulties to reconcile the handling and stability performance. To address the above problems for a through-the-road (TTR) 4-wheel-drive (4WD) hybrid vehicle, this study provides a handling and stability management (HSM) approach by incorporating the offline optimization rules and on-line model predictive control (MPC). Firstly, the vehicle dynamic model with seven degrees of freedom (7-DOF) is used to offline extract torque distribution rules (Offline-ETDR), and the online MPC feedback (Online-MPCF) is utilized to compensate the extra torque requirements for the poor effect under the extreme conditions. Accordingly, the offline optimization results and online correction are fused to provide the total torque demand given the real-time road condition detection. Finally, the real vehicle test are implemented to validate the effectiveness of the proposed torque coordination strategy. In comparison to the vehicle with no torque control strategy, the proposed method significantly improves the vehicle's cornering ability while also ensuring the high stability performance.

“…To apply the first approach, we studied lateral stability regions, with the ulterior objective of preventing the vehicle state from leaving them. We identified shortcomings in the literature, providing the contributions presented in Chapter 5 and published in (ALVES; CHINELATO; ANGELICO, 2022).…”

Aplicamos controle de segurança crítica a controle eletrônico de estabilidade, com foco em estabilidade lateral. As vantagens inerentes de controle eletrônico de estabilidade de veículos automotores e as restrições intrínsecas de segurança presentes em sistemas de emergência justificam a proposta. Os fundamentos de dinâmica e estabilidade veicular são apresentados, subdivididos em dinâmica de pneus, corpo e chassi, e controle. Segue uma introdução à teoria de funções de controle de barreira, apresentando suas propriedades, vantagens, e limitações. Inicialmente, aprimoramos e corrigimos métodos de geração de regiões de estabilidade lateral. Após, estendemos teoria de controle de segurança crítica baseada em funções de barreira de controle para acomodar controle eletrônico de estabilidade usando esterçamento ativo e frenagem diferencial. Por fim, investigamos a viabilidade de funções de barreira de controle para estabilidade veicular após as referidas extensões, concluindo que os requisitos são satisfeitos. Validamos as propostas através de simulação usando modelos cada vez mais complexos, desde modelos de segunda ordem linearizados a softwares comerciais de simulação veicular.

Lateral control is an essential safety control technology for autonomous vehicles, but the effectiveness of lateral control technology relies heavily on the precision of vehicle motion state judgements. In order to achieve accurate judgements of the vehicle motion state and to improve the control effectiveness of vehicle maneuverability and the stability controller, this paper starts with an analysis of phase plane stability. A simulation analysis is conducted to investigate the effect of the vehicle steering angle of the front wheels, the longitudinal velocity, and the tire–road adhesion coefficient on the boundary of the stability area. The stable area of the phase plane was partitioned using the proposed novel quadrilateral method, and we established a stability area regression model using machine learning methods. We analyzed the inherent connection between the lateral tire forces and the principles of vehicle maneuverability and stability control, indirectly combining the characteristics of tire forces with vehicle maneuverability and stability control. An allocation algorithm for maneuverability and stability control was designed. A co-simulation indicates that the vehicle stability controller not only accurately assesses the motion state of the vehicle but also demonstrates a considerably better performance in maneuverability and stability control compared to a controller using the traditional partitioning method of stable regions. The suggested allocation method enhances vehicle maneuverability and stability by enabling a seamless transition between the two and improving the effectiveness of stability control.
