摘要： A method for detecting the direction of travel or for detecting a change in the direction of travel of a motor vehicle which has at least two wheel speed sensor arrangements which each comprise an encoder with an incremental scale and a plurality of scale graduations and a wheel speed sensor (SEa, SEb, SEc, SEd) and are connected to an electronic control unit, wherein, when a scale graduation is sensed the wheel speed sensors each transmit a speed signal to the electronic control unit, wherein the direction of travel or a change in the direction of travel is identified at least from the order in which the speed signals occur with respect to the individual wheel speed sensor arrangements. A computer program product for carrying out all the steps of the method is also disclosed.

摘要： The present invention relates to a method of detecting straight-ahead driving according to a first straight-ahead driving detection method based on information on the rotational speed of a wheel by way of memorizing a curve parameter in a learning phase, in particular in selected driving situations, and the curve parameter is formed from the wheel speed information of one or more axles, and the reciprocal value of the curve radius is calculated from the wheel speed information to determine the curve parameter. The invention also relates to a computer program product comprising an algorithm defined by the above method.

摘要： Disclosed is a method of indirect tire pressure monitoring. The method includes: learning test variables (DIAG, SIDE, AXLE), which describe the rotational movements of the wheels; determining rolling circumference differences (ΔDIAG, ΔSIDE, ΔAXLE) from actually determined test variables and the learnt test variables; learning at least one torsion natural frequency fp for at least one tire from the oscillation behavior of the individual tires; determining at least one shift of the torsion natural frequency Δfp from at least one actually determined torsion natural frequency and from the at least one learnt torsion natural frequency; and combining the rolling circumference differences (ΔDIAG, ΔSIDE, ΔAXLE) with the at least one shift of the torsion natural frequency fp in a joint warning strategy for detecting and warning of tire inflation pressure loss.
