随着信息技术在汽车领域应用的日益广泛，轮胎-路面摩擦估计已成为一个研究热点。在这项工作中，我们遵循基于模型的方法，其中使用驱动和非驱动车轮的车轮速度差异。也许最重要的特点是，如果汽车配备了ABS刹车，只需要现有的传感器。目标是从汽车中可用的标准传感器中计算某些参数，这些参数直接或间接地依赖于摩擦力，并找到关于如何评估可用于制动或转弯的最大摩擦力的规则。
Tire-road friction estimation has become an intense research area as the interest of information technology in vehicles increases. In this work, we follow a model-based approach where the difference in wheel velocities of driven and non-driven wheels is used. The perhaps most important feature is that only existing sensors are needed if the car is supplied with ABS brakes. The goal is to compute certain parameters from available standard sensors in the car, which depend directly or indirectly on the friction, and to find rules regarding how to evaluate the maximal friction forces that can be used for braking or cornering.
