摘要:
A method for recognizing the removal of a tire provided with a tire sensor device, includes recognizing, with the tire sensor device, if a respective tire is mounted on the motor vehicle and storing an item of information relating to a mounting status in the tire sensor device. If a removal is determined, the tire sensor device sends an item of information characterizing the removal to a central control unit and the central control unit outputs a warning. A tire sensor device, a central control unit and a system for anti-theft protection through tire removal recognition, are also provided.

A device and a method for distinguishing positions of two tire sensors of a double tire include an LF antenna attached to a vehicle and connected to a central processing unit and one tire sensor each per tire. The tire sensors have a device for measuring field strength of a signal emitted by the LF antenna and the tire sensors report back information on the measured field strength through the LF antenna to the central processing unit. The central processing unit determines the position of the two tire sensors of the double tire from a distribution or course of a current flow during wheel rotation.

A method for assigning a position of a tire, having a tire sensor, on a vehicle, includes transmitting, with the sensor, a signal including at least an identification number of the sensor following activation by a signal from an LF antenna connected to an evaluation unit. At a system start time, the evaluation unit first initiates an initialization including determination of the position of each tire having a sensor. The evaluation unit stores the identification number of each sensor together with the determined position of the tire having the sensor, before switching into a normal operating mode in which tire data, for example air pressure, is monitored by the sensors, with the position and preferably assignment of the sensor to a specific LF antenna, being stored in the sensor and kept available for retrieval. A device and a system for measuring air pressure in a vehicle tire are also provided.

摘要:
A method and device for assigning a vehicle wheel to axles having different wheel sizes. The method includes measuring the acceleration “a” sensed by an acceleration sensor of a wheel electronic system in a wheel. The measured acceleration value is transmitted to an evaluation unit, which compares the measured acceleration value “a” with a standard value stored in a memory for a standard wheel. The evaluation unit assigns the vehicle wheel to an axle as a function of the comparison result. The method and device are particularly suited to determining lift axles for trucks.
摘要:
A charging device (BEV) on an vehicle (FAR), for a dual toll system (SYS), is capable of receiving positional data from a position determining system (PES), concerning the actual location of the vehicle (FAR) and to calculate location co-ordinates (OKO) for the vehicle (FAR). Said charging device (BEV) is further capable of calculating a characteristic signature (SIG) for the stretch of road (STR) traveled by the vehicle (FAR) by means of location co-ordinates (OKO) for the vehicle (FAR) and transmitting the same to an accounting centre (ABZ), outside the vehicle.
摘要:
The invention relates to a device for occupant protection in a motor vehicle and for anti-theft protection of the motor vehicle, comprising an airbag (3), which may be inflated with gas by means of a filling device, a transceiver (5), for electromagnetic waves (6) and an occupant protection analytical unit (81) connected thereto. An occupant protection interrogation unit (41) is arranged on the inflatable airbag (3), which is wirelessly interrogated by the transceiver (5). Information on the degree and/or speed of unfolding of the airbag is thus provided to the occupant protection analytical unit (81). The transceiver (5) may furthermore wirelessly interrogate a portable anti-theft interrogation unit (42), for example, a chipcard and hence provide an anti-theft analytical unit (82) with information about the authorisation of the anti-theft interrogation unit (42) and/or the separation of the anti-theft interrogation unit (42) from the transceiver (5) based on the returned signal.
摘要:
A method for controlling a power supply of a mobile data memory (MDS). The mobile data memory is operable to communicate via wireless data transfer using an antenna (A). The mobile data memory has at least one energy accumulator (BAT), a data demodulator (EMP), a data processing unit (C) and an electronic memory (MEM). The method includes switching to a standby mode from a full operation mode, the standby mode having a lower energy supply than the full operation mode but permitting receipt of the signal. When the mobile data memory receives a signal (ES), the received signal is evaluated to detect at least one backscatter frequency and an associated communication frequency (f1, f2).
