Torque vectoring is a widely known technique to improve vehicle handling and increase stability in limit conditions. With the advent of electric vehicles, this becoming key topic since it possible have distributed powertrains, i.e., multiple motors are adopted, which each motor controlled separately from others. Moreover, deliver torque required by controller faster more precisely than internal combustion engines, active differentials conventional hydraulic brakes. The state art Direct Yaw...
<div>The increased popularity of electric vehicles featuring distributed powertrains is enabling an easy and cost-effective implementation torque vectoring. This a renowned technique for controlling vehicle lateral dynamics having the objective improving both handling stability. Nevertheless, application vectoring at front axle can increase difficulty usual driving tasks. because differential longitudinal forces tires generate steering wheel torque, which be badly perceived by driver,...
With the increasing emphasis on environmental sustainability, electrification of urban public bus fleets has gained significant attention. Understanding factors influencing energy consumption battery-electric buses (BEBs) is crucial for enhancing their efficiency. Therefore, it to identify subsystems that contribute most and understand how operational influence them. This paper presents a comprehensive analysis BEB based experimental measurements performed with 12 m fully electric battery...
Sideslip angle could provide important information concerning vehicle's stability. Unfortunately direct measurement of sideslip requires a complex and expensive experimental set-up, which is not suitable for implementation on ordinary passenger cars; thus, this quantity has to be estimated starting from the measurements vehicle lateral/longitudinal acceleration, speed, yaw rate steer angle. According proposed methodology, as weighted mean results provided by kinematic formulation those...
Teleoperation provides human operator sophisticated perceptual and cognitive skills into an over the network control loop. It gives hope of addressing some challenges related to vehicular autonomy which is based on artificial intelligence by providing a backup plan. Variable time delays in data transmission major problem teleoperating vehicle. On 4G network, variability these high. Due this, both video streaming driving commands encounter variable delay. This paper presents approach forecast...
Nowadays, railway freight transportation is becoming more and crucial since it represents the best alternative to road transport in terms of sustainability, pollution, impact on environment public health. Upgrading potentiality this kind transportation, would be possible avoid delays goods deliveries due accidents, traffic jams, other situation occurring roads. A key factor framework therefore represented by monitoring maintenance train components. Implementing a real time main components...
Automobiles are becoming more and complex as multiple control systems integrated into the vehicle platform. This paper investigates coordination of active rear steering (RWS) torque vectoring (TV) – which is enabled by independent electric motors at axle in controlling lateral dynamics. The proposed controller aims enhancing handling performance stability while cornering. two actuators achieved weighting their contribution based on impact dynamics according to working condition. each system...
While rail freight transportation is gradually becoming a crucial asset in the context of decarbonization transport sector, new standards and requirements this field aim at improving safety reliability vehicles infrastructure. From perspective, Condition Monitoring Based Maintenance are essential tools to improve systems through use in-service instrumented vehicles. On contrary high-speed applications, trains actually not provided with any monitoring able carry out kind analyses. In context,...

Abstract The paper focuses on the possibility of enhancing performances ABS (Antilock Braking System)/EBD (electronic braking distribution) control system by using additional information provided 'smart tyres' (i.e. tyres with embedded sensors and digital-computing capability). In particular, basis previous works [Braghin et al., Future car active controls through measurement contact forces patch features, Veh. Syst. Dyn. 44 (2006), pp. 3–13], authors assumed that these components should be...
High-sided vehicles experience sudden changes in aerodynamic forces when passing through the wake of towers bridges under crosswind. This may lead, worst case, to vehicle rollover or undesired lane changes, thus representing a critical concern for running safety. Computational fluid dynamics (CFD) is used simulate and investigate acting on heavy goods (HGV) during overtaking maneuver bridge tower pylon generated by lateral wind. Dynamic mesh techniques are adopted relative velocity between...

A set of scaling factors has been introduced by Pacejka [Pacejka, H.B., 2002, Tyre and Vehicle Dynamics (Oxford: Butterworth Heinemann Editions)] into his Magic Formula tyre model to take account the influence a number external overall parameters such as road roughness, weather conditions, suspension characteristics so on. These are important for correct prediction tyre–road contact forces, but not function itself. Changing point view, one could say that should remain constant different...
