摘要： A friction coefficient between at least one tire of a motor vehicle and a roadway is estimated recursively. A kingpin inclination angle is detected or measured. A model determines a lateral friction value by defining a functional correlation between that value and the angle such that a non-linear course of that value relative to the angle is dependant on an initial increase of that value relative to the angle and on a recursively determined estimated value of the friction coefficient. The initial increase is defined substantially independently from the recursively determined estimated value. In addition, a measurement variable of the driving dynamics is captured. Depending on the lateral friction value, the driving dynamics model variable is determined. Furthermore, a variance between the driving dynamics measurement variable and the driving dynamics model value is determined. The recursion when acquiring the estimated value includes that the estimated value is adjusted.

摘要： In a method for estimating the height of the center of gravity of a vehicle, a lateral acceleration is determined. Predefined first and second driving situation are detected at a first time as a function of a determined roll rate or of a determined roll angle and at a second time as a function of the roll rate or of the roll angle. In a time period delimited by the first and second times, a differential angle by which a vehicle body tilts during the time period is determined. Also determined are an angular speed: formula and an angular acceleration: formula of the vehicle tilting movement in the time period. A height of the center of gravity of the vehicle is estimated on the basis of an equation of motion as a function of the lateral acceleration, of the differential angle, of the angular speed: formula and of the angular acceleration: formula.

摘要： An inertial measurement unit (IMU) contains three linear acceleration sensors and three rotational speed sensors. For the sensors there are desired installation directions parallel to the co-ordinate axes of a Cartesian co-ordinate system which is fixed to the vehicle. The actual installation directions of the sensors may differ from the desired installation directions owing to incorrect orientations. By comparing accelerations which are measured by the linear acceleration sensors for different attitudes of the vehicle with acceleration values which are known for these different attitudes in the Cartesian co-ordinate system which is fixed to the vehicle, the actual installation directions of the linear acceleration sensors are determined. By using a co-ordinate transformation it is then possible to convert the measured accelerations into the actual accelerations.
