A review on estimation of vehicle tyre-road friction

The tire-road friction coefficient (TRFC) is not only related to pavement conditions, but also affected by factors such as tire material, tire pressure and ambient temperature; in addition, there are problems such as sensor measurement noise, signal transmission hysteresis, parameter uncertainty or time denaturation in the actual vehicle system. These problems make the real-time robust estimation of the friction coefficient and its stability analysis more complicated, Therefore, the identification of TRFC has always been a key topic and difficult issue in research. This paper provides a comprehensive technical review of the currently widely used TRFC estimation method. First, various filters and observers and their improved versions to solve different problems are introduced. Then the model-based estimation algorithm is comprehensively expounded. The paper summarizes the research results of sensor-based and neural network-based methods, analyses the new method brought about by the structural characteristics of distributed drive electric vehicles to estimate the friction coefficient, and looks forward to the future development direction.
