The Low Floor electric bus, which had been promoted by the Government of Thailand, boost design technologies and research in the automotive industry. In order to fulfill the safety requirements regulated by the Department of Land Transport of Thailand, it must undergo both static and dynamic analysis. The vehicle dynamic cornering behavior plays an important role to demonstrate handling stability especially for active safety. In this paper, we study effect of the parameters of weight distribution and the road friction coefficient, which were indicated in terms of understeer gradient. The analysis had been conducted by ADAM CARS based on the vehicle's multi-body model. The analysis was applied under steady state cornering conditions based on three front to rear weight distribution configurations in percent of 50/50, 45/55 and 40/60, and a lateral tire road friction coefficient of 0.5, 0.7 and 0.9. The results show that the greater the friction coefficient between road and tire, the better handling behavior. The trends are in the same fashion when the three weight distributions are varied and the 40/60 configuration has the smallest understeer gradient. But in the real design we should consider other behavior like ride performance and static analysis, so that the configuration of 45/55 is chosen in our real design.

“…In the following context, some of the studies that have used the Dugoff tire model in order to estimate the friction or related parameters are introduced. Ghandour et al [89] developed an algorithm, using Dugoff to simulate the lateral force, to estimate the lateral friction coefficient. First, they developed an estimation algorithm to obtain the lateral force and slip angle.…”

Lack of driver's knowledge about the abrupt changes in pavement's friction and poor performance of the vehicle's stability, traction, and ABS controllers on the low friction surfaces are the most important factors affecting car crashes. Due to its direct relation to vehicle stability, accurate estimation of tire-road friction is of interest to all vehicle and tire companies. Many studies have been conducted in this field and researchers have used different tools and have proposed different algorithms. This literature survey introduces different approaches, which have been widely used to estimate the friction or other related parameters, and covers the recent literature that contains these methodologies. The emphasize of this review paper is on the algorithms and studies, which are more popular and have been repeated several times. The focus has been divided into two main groups: experiment-based and model-based approaches. Each of these main groups has several sub-categories, which are explained in the next few sections. Several summary tables are provided in which the overall feature of each approach is reviewed that gives the reader the general picture of different algorithms, which are widely used in friction estimation studies.

Road Friction Virtual Sensing: A Review of Estimation Techniques with Emphasis on Low Excitation Approaches

Abstract:In this paper, a review on road friction virtual sensing approaches is provided. In particular, this work attempts to address whether the road grip potential can be estimated accurately under regular driving conditions in which the vehicle responses remain within low longitudinal and lateral excitation levels. This review covers in detail the most relevant effect-based estimation methods; these are methods in which the road friction characteristics are inferred from the tyre responses: tyre slip, tyre vibration, and tyre noise. Slip-based approaches (longitudinal dynamics, lateral dynamics, and tyre self-alignment moment) are covered in the first part of the review, while low frequency and high frequency vibration-based works are presented in the following sections. Finally, a brief summary containing the main advantages and drawbacks derived from each estimation method and the future envisaged research lines are presented in the last sections of the paper.
