A method for indirectly monitoring tire pressure or for detecting damage to a wheel suspension, wherein a pressure loss detection variable (DVE) is determined using an analysis of a vibratory behavior of a wheel of a motor vehicle, and a pressure loss in the tire of the wheel or damage to the wheel suspension is detected by comparing a momentarily determined pressure loss detection variable (DVE) to a learned pressure loss detection variable (DVE), wherein at least two dimensional variables are determined from a wheel speed signal (w) of the wheel, each representing a dimension for the extent of a frequency or a frequency range in the vibratory behavior of the wheel, and that the pressure loss detection variable (DVE) is derived from the two dimensional variables (e, e, e), particularly from a ratio of the two dimensional variables (e/e), and a tire pressure monitoring system.

Method for indirectly monitoring tire pressure and tire pressure monitoring system

A system and method for indirect tire pressure monitoring. A pressure loss variable (X, f, c) is determined based on an analysis of an oscillation behavior of a tire of a motor vehicle for the detection of a pressure loss in the tire of a wheel. A variable (&#x3b1;, &#x3b1;/v) representing an increase (&#x3b1;) of a wheel torque slip curve, or depending on an increase (&#x3b1;) of a wheel torque slip curve (&#x3b1;/v), is determined from the oscillation behavior of the tire, and the variable (&#x3b1;, &#x3b1;/v) and the pressure loss variable (X, f, c) are used for detecting the pressure loss.

Method for indirect tire pressure monitoring and tire pressure monitoring system

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

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.

Method and system for assisting a driver when parking or maneuvering a motor vehicle

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.
