The invention relates to a device for determining a tendency to tilt about the longitudinal axis and a tendency to turn about the vertical axis of a vehicle. The detection system is characterized by a lateral acceleration sensor producing a lateral acceleration signal, a yaw rate sensor producing a yaw rate signal, a steering angle sensor producing a steering angle signal, wheel speed sensors producing the rotation signals of the wheels, and which includes a controller which, in response to the steering angle, the steering velocity and the vehicle speed, determines a tendency to tilt about the longitudinal axis of a vehicle and which, in response to the lateral acceleration sensor, the yaw rate sensor, the steering angle sensor and the wheel speed sensors determines the tendency to turn about the vertical axis of the vehicle, and with the controller generating a triggering signal for at least one passenger protection means depending on the extent of these tendencies.

The invention relates to a method of calibrating a sensor, in particular a yaw rate sensor, in which sensor values (Y) and associated temperature values (T) are stored in the shape of reference points in a non-volatile memory of the sensor, in which case the values (Y, T) are determined during a calibration mode in which the sensor is exposed to a predefined temperature profile. In order to further improve the accuracy of the calibration, the invention discloses that the values (Y, T) determined in the calibration mode are used to determine coefficients (C, . . . , C, C) of a polynomial of nth order, and these coefficients are stored.

The present invention relates to a system for transmitting tire condition variables from a transmission device mounted on a motor vehicle to an electronic evaluating or control unit arranged in the area of the vehicle body, which is detachably fastened to a motor vehicle wheel described hereinbelow for providing an electromechanical compound arrangement. Further, a transmission device is disclosed wherein tire condition variables can be detected, and wherein a coupling device is integrated into the wheel hub () and composed of a rotor and a non-rotating stator for producing a field coupling, and its one or more field coupling elements are arranged opposite one another, separated by a narrow air slot (), and energy and/or signals are coupled by means of electric fields and/or magnetic fields and/or electromagnetic fields. Still further, the system contains a vehicle wheel equipped with sensors, consisting of wheel rim (), pneumatic tire (), and a sensor subassembly () which rotates with the wheel. The wheel has a signal connection that can be connected to the transmission device.

The invention discloses a method for compensating temperature in a system for tire pressure monitoring which is especially implemented by detecting a tire pressure and/or by detecting a tire pressure loss. The method is especially characterized in that the temperature is compensated by determining the gas temperature in the tire by way of at least two items of temperature information and by taking the determined temperature as a basis for said tire inflation monitoring. One significant advantage of this method involves that externally active temperature changes, such as a heat-emitting brake disc causing the wheel rim of the tire and, hence, also a temperature sensor arranged thereat to be heated more intensely than the gas in the tire, do not lead to an indication error with respect to the tire pressure (or a spurious alarm).

An additional active motor vehicle suspension can also be provided.
