Additionally, steer-by-wire technology is gaining attention, enabling electronic control of steering, further revolutionizing the driving experience. One cannot overlook the significance of braking systems within the realm of chassis control. The braking system ensures the vehicle's ability to decelerate and stop safely. Traditionally, hydraulic braking systems have been used, but advancements such as anti-lock braking systems (ABS) and regenerative braking have been introduced. ABS prevents wheel lock-up during emergency braking situations, enhancing control and stability. Regenerative braking, commonly found in electric and hybrid vehicles, converts kinetic energy into electrical energy, increasing overall efficiency [4]. Traction and stability control systems play a pivotal role in maintaining vehicle stability and preventing accidents. Traction control systems manage wheel slip during acceleration, ensuring maximum traction even on slippery surfaces. Electronic Stability Control (ESC) combines various sensors and control mechanisms to automatically detect and correct lateral skidding or loss of control [5]. It is an essential safety feature in modern vehicles, significantly reducing the risk of rollovers. Automotive chassis control technology encompasses various systems and components that work together to improve vehicle performance, stability, and safety. From suspension and steering to braking and traction control, each component plays a crucial role in ensuring a smooth and safe driving experience [6]. With advancements in technology, the integration and communication between these components have become more sophisticated, promising even more exciting developments in the future. The article provides a comprehensive review and discussion on automotive steering/braking/driving/suspension systems, analyzing their system composition, technological status, and key technologies. Firstly, it introduces fault-tolerant techniques in wire-controlled systems, including hardware redundancy and software redundancy. Hardware redundancy backup can improve system reliability, while software redundancy relies on fault-tolerant algorithms in the controller to increase system redundancy. These two types of redundancy techniques have strong complementarity, and this complementary design ensures that the system can maintain a high performance level when facing a fault, greatly reducing the risk caused by failures and providing strong support for improving the stability and reliability of wire-controlled systems. The article focuses on wire-controlled braking systems and introduces an optimized braking force distribution strategy to ensure vehicle safety and stability. This strategy not only improves braking efficiency but also enhances vehicle stability. In addition, it introduces the application of in-wheel motor drive systems in wire-controlled driving systems. This system can be flexibly placed on the wheels of electric vehicles and has the advantages of high integration and flexible driving.
