Abstract
For the optimization of advanced driver assistance systems (ADAS) and the implementation of autonomous driving, the perception of the vehicles environment and in particular the maximum friction coefficient μ max is crucial. Since μ max cannot be measured directly via existing serial sensors, estimating this coefficient based on available sensors is an area of research. In this paper, μ max estimation is presented using transformer neural networks (TNN) based on the input data measured by onboard vehicle sensors. The TNN is applied to both a simulative dataset created with IPG CarMaker and an experimental dataset recorded on a test track, each using a sports utility vehicle (SUV) as the test vehicle. Both datasets contain typical longitudinal and lateral driving maneuvers on different road surfaces. On an independent test dataset, the data-based TNN approach shows improved results in estimating μ max compared to the model-based approach of an unscented Kalman filter (UKF) and to two other data-based approaches using recurrent artificial neural networks (RANN s) from previous works. In particular, the TNN responds faster and more accurate to jumps of μ max, especially during lateral driving maneuvers. Moreover, the TNN has both less parameters, and training epochs compared to the RANN.
