In the context of the major trends toward electrification and intelligence in automobiles, the chassis system, which bears the core functions of vehicle driving, is undergoing a profound transformation from traditional mechanical chassis to x-by-wire chassis. The x-by-wire chassis, which uses electric power to operate and controls braking, driving, steering, and other functions through electrical signals, has great potential for the improvement of various aspects of automotive design, dynamics control, and intelligent driving and has become the focus of domestic and international competition. It is urgent to carry out a forward-looking layout of the x-by-wire chassis to achieve the continuous leadership of China’s new energy vehicle technology. This paper conducts a thorough analysis of the global development status of the x-by-wire chassis, systematically organizing the latest advancements and key technologies in its main subsystems, structures, and control areas. It examines and forecasts future trends in x-by-wire chassis development and also offers suggestions for its advancement based on current shortcomings and challenges in China’s x-by-wire chassis technology and industry.

The widespread use of wired control systems, such as steer-by-wire, drive-by-wire, brake-by-wire, suspension-by-wire, and different levels of driver assistance systems, such as anti-lock brake systems, lane keeping systems, adaptive cruise control, and lane change assist systems, result in redundancies and conflicts in the control of the vehicle chassis. The distributed driving format provides more possibilities for efficient and cooperative control between the multiwire control and auxiliary driving systems. This paper highlights the latest progress in distributed drive electric vehicle integrated control technology in terms of integrated control strategy architecture, longitudinal-lateral integration control, lateral-vertical integration control, longitudinal-vertical dynamic integrated control, longitudinal-lateral-vertical dynamic integrated control, fault-tolerant control, and chassis dynamics integrated control for distributed drive intelligent electric vehicles.

Two-stage auxiliary drifting path tracking control for distributed driving three-axle commercial vehicles[J]. ISA Transactions, 2024, 153: 404-419., articleTitle=Two-stage auxiliary drifting path tracking control for distributed driving three-axle commercial vehicles, refAbstract=When maneuvering corners at high speeds, commercial vehicles experience significant sideslip angles and tire force saturation, which can lead to severe traffic accidents. Incorporating intelligent driving technology to develop a controllable scheme that surpasses stability constraints and maintains the vehicle in a drift state is crucial for enhancing driving safety. Therefore, based on the model characteristics of distributed drive three-axle(DDTA) commercial vehicles, a two-stage auxiliary drift controller is proposed. In the auxiliary drift stage, time-varying model predictive control (MPC) is employed to track the desired states and achieve steady-state drift path tracking under extreme working conditions. A two-stage controller switching strategy is implemented based on road information. In the yaw stability control stage, an advanced auxiliary system facilitates cooperative control to smoothly restore tire attachment and vehicle yaw. Simulation results demonstrate that the control strategy ensures consistent path tracking performance even when adhesion of the middle and rear axle saturates and peak vehicle sideslip angle reaches 32.09°. After completing the drifting, vehicle yaw successfully returns to a stable state. Subsequently, miniaturized vehicle tests qualitatively analyze relevant conclusions by elucidating transient instability evolution in vehicles subjected to steering and distributed drive. The controllable stability boundary of the vehicle is thus expanded, thereby enhancing the engineering feasibility of drift technology.Copyright © 2024 ISA. Published by Elsevier Ltd.

In the context of the major trends toward electrification and intelligence in automobiles, the chassis system, which bears the core functions of vehicle driving, is undergoing a profound transformation from traditional mechanical chassis to x-by-wire chassis. The x-by-wire chassis, which uses electric power to operate and controls braking, driving, steering, and other functions through electrical signals, has great potential for the improvement of various aspects of automotive design, dynamics control, and intelligent driving and has become the focus of domestic and international competition. It is urgent to carry out a forward-looking layout of the x-by-wire chassis to achieve the continuous leadership of China’s new energy vehicle technology. This paper conducts a thorough analysis of the global development status of the x-by-wire chassis, systematically organizing the latest advancements and key technologies in its main subsystems, structures, and control areas. It examines and forecasts future trends in x-by-wire chassis development and also offers suggestions for its advancement based on current shortcomings and challenges in China’s x-by-wire chassis technology and industry.
