A Comparative Study of Discomfort Using Electrical and Friction Braking at Low Speed Driving

Paper i proceeding, 2024

In this study, we conduct an analysis of the longitudinal dynamics of a vehicle model in an incline, with a specific focus on its behavior, at low speeds, when starting and stopping. The model is minimal, yet an effective representation of a vehicle that includes the effects of springs and dampers as well as friction and electric braking models, which allows for easy analysis into their interplay at low speed. One important feature that this early study shows is how the acceleration and jerk is affected by static and dynamic friction coefficients in different driving situations. Our study further demonstrates the interplay between the electric and friction braking systems and the differences in oscillatory motion they generate. Such insights are vital if we want to improve vehicle control at low speeds and suggest ways to reduce problems like excessive acceleration and jerk. Additionally, our findings could also provide valuable insights when developing active friction braking systems.
