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.

Method for detecting the direction of travel of a motor vehicle

Method for monitoring the state of a tire, in which at least one analysis value (Ui), from which the state of a tire is determined, is formed from wheel speed signals (&#x3c9;i) of the vehicle wheels, wherein the analysis value (Ui) is an absolute rolling circumference of a tire or a variable which represents the absolute rolling circumference of a tire, in particular a dynamic tire radius which is determined by evaluating wheel speed signals (&#x3c9;i) and signals from at least one sensor in order to measure the speed of the vehicle over an underlying surface, and the analysis value (Ui) is used to determine a loss of pressure and/or working loads of the tire, as well as a device for monitoring the state of the tire.

Method and device for monitoring the state of tires

A method for assisting a driver when parking or maneuvering a motor vehicle having at least one driver assistance system and a vehicle safety system is provided. The method includes the steps of detecting the surroundings and calculating a desired path in a calculation model, in which the differences in traveling distance between the individual wheels are monitored and determined by means of the vehicle safety system. The desired path is predicted in a calculation model by means of the differences in traveling distance, and detection of the surroundings is carried out by means of the driver assistance system. Furthermore, a system which is suitable to implement the method is provided.

Disclosed is a method for detection of a pressure loss in motor vehicle tires, which detects pressure loss on at least one vehicle tire based on several parameters, which are calculated from the rolling circumference of the tires. To this end, currently calculated parameters are compared with learnt values of the parameters.
