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 Modeling and Control of a 4-Wheel Narrow Tilting Vehicle

Abstract: The automotive industries currently face challenges such as emission limits, traffic congestion, and limited parking, which have prompted shifts in consumer preferences and modern passenger vehicle requirements towards compact vehicles. However, given the inherent narrowness of compact vehicles, the potential risk of vehicle rollover is greater than that of regular vehicles. This paper addresses the safety concerns associated with vehicle rollover, focusing on Narrow Tilting Vehicles (NTVs). Quantifying stability involves numerical indicators such as the Lateral Load Transfer Ratio (LTR). Additionally, a unique approach is taken by applying ZMP (Zero Moment Point), commonly used in the robotics field, as an indicator of vehicle stability. Effective roll control requires a detailed analysis of the vehicle's characteristic model and the derivation of lateral and roll dynamics. The paper presents the detailed roll dynamics of an NTV with a MacPherson strut-type suspension. A stability-enhancing method is proposed using a cascade structure based on an internal robust position controller, addressing challenges posed by disturbances. Experimental verification using Simscape Multibody and Carsim validates the dynamic model and controller's effectiveness, ensuring the reliability of the proposed tilting control for NTVs in practical scenarios.
