The technology of electronic steering with force feedback is related to electronic vehicle control. This technology is also known as "steer-by-wire" technology and is specific in that there is not any mechanical connection between the axle and the steering wheel. This technology is currently not very widespread. However, developments in the automotive industry are slowly moving towards this technology in the context of autonomous vehicles. This study includes a review of current technologies in this area and suggests a technical solution for Steer-by-Wire technology and its verification in the real vehicle model in the university environment.

The steering trapezoid designed according to the Ackermann steering geometry potentially causes excessive tire wear and affects the steering performance due to the large tire deformation resulting from large lateral acceleration. To address these problems, this article introduces a design method for a race car steering system that considers the tire side slip angles to optimize the target steering angle relation. First, a racing path was planned by genetic algorithm according to the given race track and race car driver characteristics. Next, the objective function of the ideal steering angle relation was constructed by introducing the Ackermann correction coefficient and establishing the modified Ackermann steering geometry model, considering the tire side slip angle. Then, a data acquisition experiment was designed, and the Ackermann correction coefficient was identified by the proposed simulation algorithm. Finally, the coincidence degree of wheel steering centers was defined as the evaluation index, which can be used to describe and evaluate the performance of the coordination for wheels’ movement. Simulation results show that the design method of the steering system effectively improves the handling stability of the race car and reduces the tire leaning-grind.

Nowadays, a concept of tilting three-wheel vehicle is introduced, one of which is the electric tilting tricycle to provide an alternative mode of transportation. Some of the tilting tricycle design usinga tadpole trike configuration and it needs an adequate steering system that can be synergized with tilting mechanism. The steering mechanism follows the Ackermann steering geometry. Usage of Ackermann geometry means applying a mechanism of trapezoidal four-bar linkage to the tricycle. To create and maintain the simple trapezoid shape, Triple Ball Tie-rod model, a single rod which supports three ball joints, is proposed. Since the capabilities of the model are yet to be proven, this research evaluates the usageof a tie-rod model to find out its capabilities to support the works of the steering mechanism of the tricycle. The measurements are conducted after the simulation of the 3D model to extract some data such as maximum lean angle and inner and outer steering angles. Another simulation using regular tie-rod model also conducted with the same method for comparison purposes. The results of the study are maximum allowed tilting angle and generated Ackermann steering angles. Each designed models have their respectiveadvantages.
