Method for determining coefficient of friction of lane

The invention relates to a method for determining a current lane friction coefficient ([mu] road) by means of a control device in a motor vehicle, in which a current friction coefficient demand ([mu] dem) is continuously calculated by means of the control device, in which a current tire stiffness (St) is determined from the calculated current friction coefficient demand ([mu] dem) and a current tire slip (Slip), and determining a current lane friction coefficient ([mu] road) from the current tire stiffness (St) by means of a stored table (T) that maps the tire stiffness (St) to the lane friction coefficient ([mu] road). 一种用于通过机动车辆中的控制设备求取当前车道摩擦系数(μroad)的方法，其中通过控制设备连续计算当前摩擦系数需求(μdem)，其中从所计算的当前摩擦系数需求(μdem)和当前轮胎打滑(Slip)中确定当前轮胎刚度(St)，并且借助于所存储的将轮胎刚度(St)映射到车道摩擦系数(μroad)上的表格(T)从当前轮胎刚度(St)中求取当前车道摩擦系数(μroad)。
