Modeling and Control for Chassis Devices in Electric Vehicles

Dear Colleagues,

You are invited to submit papers to a Special Issue of Actuators on “Modeling and Control for Chassis Devices in Electric Vehicles”. The most notable innovation in electric vehicles (EVs) is the electric power source. The electric power common in EVs has changed classical chassis devices such as steering, braking and suspension in vehicles with a internal combustion engine. This trend requires new modeling and control techniques with motor-driven actuators for EVs. A representative example is in-wheel motors or the e-corner module, equipped with an electro-mechanical brake (EMB), motor-driven active suspension and steer-by-wire devices. These devices and their combinations can be used for specialized functions such as ABS, TCS, ESC and rollover prevention control. In addition to the control of each device in EVs, it is also necessary to integrate them for path tracking, vehicle stability and ride comfort enhancement. In addition to those devices themselves, the modeling and control of sensors and actuators used for those devices are also needed. All these factors should be properly considered in studies on modeling and control for chassis devices in EVs.The topics that will be considered include, but are not limited to, the following:

• Modeling on new types of actuators for EVs;
• State and parameter estimation for EVs;
• Motor-driven ABS, TCS and ESC for EVs;
• Advanced steering control for EVs;
• Active/semi-active suspension control for EVs;
• Coordinated control with multiple actuators for EVs;
• Path tracking control with multiple actuators for EVs;
• Energy-saving control and optimization for EVs;
• Fault-tolerant control for EVs

This topic will handle issues in the modeling and control of actuators, which originate from chassis devices such as the electro-mechanical brake, motor-driven active suspension and steer-by-wire. These devices should be controlled for specialized functions such as ABS, TCS, ESC and rollover prevention in real electric vehicles. For the reason, this topic fits well in the scope of “Actuators”.

Title: Dynamic Envelope Optimization of Multi-Axle Vehicles Based on Coordinated Steering Control Strategies
Authors: Zhaocong Sun; Wenjun Wang; Joshua Meng

Abstract: The technique of steer-by-wire, essential for autonomous driving, enables multi-axle and multi-wheel turns on modern chassis to facilitate two typical applications. First, it allows vehicles to navigate through challenging conditions like tight turns and narrow lanes. Second, it enhances the road access of articulated vehicles with a shrunken lateral turning offset compared to the traditional single-axle steering structure. The performance of lateral offset during vehicle turns is defined as the vehicle dynamic envelope, which is analyzed through numerical optimization and dynamic simulations. The paper compared the dynamic envelope results across using various coordinated control strategies for single-body and articulated vehicles, demonstrating the impact of multi-axle steering control on road access capabilities. Additionally, the study provided insights into designing autonomous-driving turning trajectories and the corresponding dedicated road layouts.
