Improved Vehicle Handling through Wheel-Individual Vertical Actuation in Low-Friction Conditions
Paper i proceeding, 2026
This paper presents the development and validation of a dynamic motion model of an electric bus equipped with a hydro-pneumatic suspension system. The model is validated against experimental data from a real electric bus and is used to evaluate the effects of individual-wheel vertical actuation on vehicle behavior under low-friction road conditions. Simulations and experimental results demonstrate that the proposed model can represent key vehicle dynamics with sufficient accuracy to assess vehicle performance and support the development of safer, more robust suspension systems for electric buses. The study also examines how individual wheel-suspension actuation improves handling and acceleration performance of electric buses.
