“…Urban vehicles have been introduced to deal with energy consumption, traffic problems, air pollution, and parking limitations in large cities. 24,25 They are smaller and narrower than conventional vehicles; thereby, cambering is potentially more effective for them. While limited studies have been conducted about active camber systems, this work investigates cambering effects on vehicles’ behavior in detail.…”

A suspension system with the capability of cambering has an additional degree of freedom for changing camber angle to increase the maximum lateral tire force. This study investigates the effects of cambering on overall vehicle stability with emphasis on applications to urban vehicles. A full vehicle model with a reliable tire model including camber effects is employed to investigate the vehicle dynamics behavior under cambering. Besides, a linearized vehicle model is used to analytically study the effects of camber lateral forces on vehicle dynamics. Vehicle behavior for different configurations of camber angles in front and rear wheels is studied and compared. Then, an active camber system is suggested for improvement of vehicle lateral stability. Specifically, performances of active front camber, active rear camber, and their combination are investigated. The results show that a proper strategy for camber control can improve both yaw rate and sideslip angle, simultaneously. Finally, the active front camber system is compared with the well-known active front steering. It is shown that, utilizing more friction forces at the limits, active front camber is more effective in improving maneuverability and lateral stability than active front steering.

“…This construction solution, however, also provides a set of disadvantages resulting from the static behaviour of the contact point of the steered wheel with the road in the conception with the steered front wheel. Although the rotation of the wheel takes place to the left and right, the position of the contact point is almost permanent which has a considerable impact on the stability of the three-wheeled vehicle for driving in the curve [41][42][43]. The solution of the stated issue consists of the mounting of the front wheel fork into a rotary of a mounted element and a joint.…”

Nowadays the automotive industry is mainly focused on competition, and this fact forces vehicle producers to constantly look for improvements in the areas of quality and reliability. Life-span, flawless operation, and safety are directly interconnected. Therefore, much attention and resources are spent on research factors that affect the stated properties. Significant capital is invested in the optimization of the constructional solutions and innovative material applications related to the safety and durability of the constructions. This paper presents the results obtained while developing a new ecological three-wheeled vehicle. The main research areas were focused on replacing the original material with a light aluminum alloy, while achieving a substantial improvement in drivability for the three-wheeled vehicle by implementing a modified front wheel steering system. The submitted research achieved a weight reduction of the frame by 40 kg by applying light material substitution (EN AW 6063.T66), which will naturally have a positive impact on the range of the designed electric vehicle; furthermore, we implemented an innovative steering mechanism optimized during the experimental operations.

Significant with the increasing expense of fossil fuel and its depletion, and the impacts emission gases from petrol vehicles are having on our atmosphere, an alternative was needed. The design and fabrication of prototype battery electric vehicles is winding up progressively especially three wheel one. Three wheeled battery electric vehicles need the most ideal design conceivable to minimize the extent of energy necessary to power the vehicle. One of the paybacks of an incorporated design is a lighter vehicle, with high efficiency as a design objective focus. The lighter the vehicle, the lesser amount of energy it will necessitate to drive, therefore less greenhouse emissions. Three-wheel electric vehicle services are: university campus, clubs, hospitals, airports, residential compounds, villas, car and goods towing, trailer to haul the trash, remote area transportation etc. This work entails for investigation, design and building of a prototype three-wheeled battery drive electric vehicle with entire simple control system. A three-wheeled battery electric vehicle as an electric mobility is being developed and tested at Suez Canal University (Egypt) and Sepang International Circuit (Malaysia). The design of the three-wheeled battery electric vehicle must have many favorable characteristics such as low mass and good aerodynamics. The vehicle designed with one seat to be thrusted by brushed motor attached on the rear wheel and powered by 48V Lithium-ion battery. The numerical study is performed by MATLAB Simulink 2017 modeling and the results recorded 140km/kWh with regenerative braking system. The fabricated three-wheel battery electric vehicle total weight is 55kg. Its tested in different tracks, many attempts, with best result 100km/kWh. Vehicle maximum speed is 60km/h and the maximum efficiency is 70% at 25km/h.
