143239 - Estimating the Tire-Road Friction Coefficient by Inertial Measurement Unit 

Accurately modeling vehicle dynamics for simulation, analysis, or control requires a precise tire friction model. The friction forces influence the vehicle's movement on the road. Significant research considers the mathematical model of pneumatic-road friction, primarily driven by advancements in high-performance Antilock (ABS) braking systems, traction control, and steering systems. This proposed study thoroughly examines recent developments and trends in this area, focusing on providing a broad perspective of multidisciplinary initiatives and techniques for related research. The proposed strategy for estimating the coefficient of friction value is extensively analyzed and tested through simulations and data collected on an instrumented test vehicle. Although numerical and analytical models have their merits, they have limitations when modeling complex phenomena. Thus, current research points towards an experimental investigation approach that considers factors such as tire temperature, speed, and surface. The practical method being employed now involves assessing the interaction between the tire and the road profile to provide an estimation of friction and rolling resistance. Analytical and numerical models can have their limitations when attempting to model a complex phenomenon. As a result, this research suggests utilizing an experimental investigation approach that considers the impact of temperature, speed, and tire surface. This method is grounded in reality, considering the organic interplay between the tire and road profile when estimating friction and rolling resistance.
