“…In the TEV system, EVs travel autonomously in platoons at high speeds of 200 km/hr and small intervehicle distances, as shown in Figure 1. Driving in convoys with close intervehicle spacings is a technique that reduces overall aerodynamic drag and hence increases overall system efficiency [8]. Therefore, the TEV system can be an efficient dynamic charging platform for EVs to avoid the limitations of available charging systems.…”

The integration of electric vehicles (EVs) as an environmentally sustainable alternative to traditional fossil fuel cars faces a range of technological obstacles, including battery technology, charging infrastructure, and standardization. Dynamic conductive road charging (DCRC) of EVs at high speed has the potential to overcome the technical limitations of existing static charging methods. An intelligent motorway system for EVs called tracked electric vehicle (TEV) was proposed to incorporate the latest technologies of dynamic road charging, autonomous driving, and smart city data into transport infrastructure. This paper presents the operation and control of an active bipolar power collection unit (PCU) for the TEV system. The PCU is seamlessly integrated within the wheel structure of an EV using the concept of a stationary-hub wheel, enabling conductive power transfer from roadside conduction rails while the vehicle is in motion. The PCU is equipped with various features designed to maintain the contact force (CF) with the conduction rails, effectively handle instances of wheel bouncing and vibrations, and ensure a consistently smooth dynamic power transfer. This paper presents the experimental validations of the active PCU controls, including the operation sequence of the PCU, CF control, and PCU interaction with wheel bouncing.

“…This short length reduces the overall aerodynamic drag coefficient of all cars including the front car. Such arrangement can save power and in [26] it is claimed that a power saving of 40% for the whole platoon is possible as compared to a scenario in which all 10 cars are driving individually (not in a platoon). The challenge with TEV is the control of short distance at high speed.…”

Vehicle platoon systems are widely recognized as key enablers to address mass-transport. Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) are two technologies that drive platooning. The inter-vehicle spacing and collaboration velocity in the platoon are important parameters that must be controlled. A new mass-transport system called the Tracked Electric Vehicles (TEV) has been proposed which has reduced the inter-vehicular spacing to only a quarter of the regular car length. This enables mass transport at uniform speed for cars with speed of 200km/h. However, conventional radar based adaptive cruise control (ACC) system fail to control each vehicle in these scenarios. Lately, sliding mode control (SMC) has been applied to control platoons with communication technology but with low speed and without delay. This paper proposes a novel SMC design for TEV using global dynamic information with the communication delay. Also, graph theory has been employed to investigate different V2V communication topology structures. To address issues of node vehicle stability and string stability, Lyapunov candidate function is chosen and developed. Additionally, this paper uses first-order vehicle models with different acceleration/deceleration parameters for simulation validations under communication delay. The results show that this SMC has a significant tolerance ability and meets the design requirements of TEV.
