摘要: A method in which the driving behavior of a vehicle is influenced as a function of data on the surroundings in order to assist an avoidance maneuver, as soon as a risk of a collision is detected on the basis of the data from one or more environment sensors, in particular radar sensors and/or cameras, and the data from one or more vehicle sensors, in particular a steering angle sensor and/or yaw rate sensor and/or wheel speed sensors, and the vehicle has an electronically controlled brake system which permits a driver-independent buildup and modulation of the braking forces at the individual wheels of the vehicle, wherein when a risk of a collision is detected, in a first phase a turning-in operation by the driver is assisted and/or in a second phase a steering operation by the driver is damped. Furthermore, an electronic control unit for a brake system is defined.

摘要: A method for a driver assistance system for a vehicle is specified, wherein objects in the surroundings of a vehicle are detected on the basis of data of a system that covers the surroundings, and a potential free zone in which only no objects and/or objects which the vehicle can drive over have been reliably detected is determined. The potential free zone is verified by further vehicle and/or surroundings information.

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 determining a coefficient of friction between a motor vehicle tire of a motor vehicle and the surface of a roadway, a first coefficient of friction parameter (μest—used,ij) is determined using a model (RM) in which a functional correlation between the first coefficient of friction parameter (μest—used,ij) and a slip (Sij) of the motor vehicle tire is set. A second coefficient of friction parameter (μquasi—meas—used,ij) is determined from the quotient between a longitudinal force (FL) and a vertical force (FZ) of the motor vehicle tire. The first and the second coefficient of friction parameters (μest—used,ij, μquasi—meas—used,ij) are used to determine the coefficient of friction (μR,ij) by a recursive estimation algorithm.
