“…In this study, steel (St 37) with higher strength values than aluminum was preferred because safety was at the forefront as chassis material, see Table 2. The three-wheeled chassis is a new intelligent transport system that is a more convenient alternative to the mobility of the vehicle than other four-and two-wheeled vehicles [36]. The vehicle is designed to carry two passengers in the rear seat and one driver in the front seat, single and three-wheeled.…”

With technological developments and carbon emission reaching dangerous levels in the world, it is inevitable that electric vehicles will become the dominant transportation technology of the future. Studies on electric vehicles have become very popular today. In the automotive sector, sectoral dynamics and needs are rapidly changing; restrictions and demands are bound by strict rules and high value-added innovative studies are applied intensively. Supporting this area with academic data will contribute to research and development activities in this field. In this study, analysis and production studies were performed on a 3-wheeled vehicle chassis driven by electric energy. The chassis structure was designed and analyzed with details. The chassis aimed to be produced as a result of the study was analyzed in detail according to brake, modal and cornering analysis. As a result of these analyses, it was found that this chassis has a reliable structure according to the specified driving dynamics parameters. By adopting new requirements, technologies and analysis outputs for the system, a modular platform structure that can be used for various applications were created. The design and production processes of an innovative and applicable chassis structure for the electric vehicle ecosystem are given in detail.

This paper presents a new direct tilt control (DTC) design to improve the lateral stability and the driving comfort of narrow tilting vehicles. To this end, a conceptual model is constructed from the vehicle dynamics, a simplified model of the driving environment, and the vehicle perceived acceleration. This latter is considered as the main performance variable of the related H2 control problem. The conceptual model is then represented in a polytopic linear parameter varying (LPV) form for control purposes. To avoid the use of costly vehicle sensors while favoring the simplest control structure for real-time implementation, a new LPV static output feedback (SOF) control method is proposed. Thanks to Lyapunov stability arguments, physical constraints on both system states and DTC actuator are explicitly considered in the design procedure to improve the safety and the comfort of passengers. Moreover, a parameter-dependent Lyapunov function is exploited for theoretical developments. In this way, the finite bounds on vehicle speed and acceleration are effectively taken into account in the control design to reduce the conservatism. The H2 control design is recast as an LMI-based optimization which can be easily solved with numerical solvers. The resulting robust DTC controller is evaluated with realistic driving scenarios.

“…6 In order to ease this issue, researchers have been focusing on the development of an active tilt control system for the narrow 3Ws. 1,[7][8][9][10][11][12] The active tiltcontrolled narrow 3Ws, equipped with a closed cabin, aim to offer comfort like four-wheelers and manoeuvrability like two-wheelers without compromising speed. However, key factors require attention in bridging the gap between the state-of-the-art and the successful technological development of the active tilt-controlled narrow 3Ws.…”

The active tilt-controlled narrow three-wheelers (3Ws) equipped with a closed cabin aim to offer a comfortable driving experience comparable to four-wheelers while maintaining the manoeuvrability of two-wheelers without compromising on speed. Based on this concept, this study explores a tilt control strategy for narrow 3Ws. While previous research has established a steady-state tilt angle considering a zero-track width, this study incorporates track width due to the multi-wheel axle configuration. This novel approach not only withstands unbalanced lateral acceleration but also saves significant tilting torque. Unnecessary tilting is minimised by introducing a tilt actuation system (TAS) based on a unique dynamic rollover index. Central to the original contribution is the stability margin (SM), a dynamic rollover-safety index considering longitudinal and lateral dynamics, surpassing the traditional rollover index load transfer ratio, particularly for delta 3Ws. This work proposes a desired SM threshold-dependent steady-state tilt angle, activating TAS only when necessary. This pioneering method optimises the desired SM threshold using goal programming. Additionally, this research addresses a critical oversight in previous studies by accounting for the influence of road slopes, ensuring consistent stability across diverse road conditions. It is crucial to note that the proposed rollover index-based tilting approach markedly outperforms the conventional methods, reinforcing its originality and potential for future vehicular design.
