The application relates to a device and to a method for detecting a Dedicated Short Range Communication (DSRC) signal in a motor vehicle, in particular having a module with a 'C2X' communication system and/or 'Car2Car' communication system of a motor vehicle, wherein after amplitude demodulation of a received signal, one or more properties of the received signal are examined by a protocol detector.

Method for detecting a DSRC signal in a motor vehicle

The present disclosure relates to a method and devices for transit-time-based distance measurement and the teachings may be applied to locating keys for a motor vehicle. In one embodiment, a system for detecting the distance between a vehicle and an associated key may include: a transceiver associated with a vehicle; a key for the motor vehicle; and a processor configured to determine an estimated signal transit time between the transceiver and the key based at least in part on a ratio of a length of two time intervals between the transmission or reception of a message between the transceiver and the key.

Key location system

A method for allocating a transmission signal to a transmission channel which has a transmission bandwidth and a rated center frequency and which is established between a radio transmitter and a radio receiver has the steps: emitting the transmission signal on the radio transmitter end with an actual transmitter frequency; receiving the transmission signal in the radio receiver; determining the frequency of the transmission signal in the radio receiver; and deciding on the allocation of the transmission signal to a transmission channel if the frequency determined by the radio receiver lies in a predetermined frequency range.

An anti-theft system, especially in the form of an access and/or starting system for a vehicle has a vehicle-mounted receiver for receiving a request signal containing the instruction to find out whether objects that are associated with the vehicle, e.g. lost identifiers, are located in specific areas of the vehicle. The anti-theft system further has a vehicle-mounted control and evaluation unit for verifying whether the objects are in the specific areas of the vehicle and outputting information on whether an object that is associated with the vehicle has been found. The anti-theft system finally has a vehicle-mounted transmitter for transmitting a result signal containing the information on whether objects have been found. Such an anti-theft system allows an identifier, for example, which is associated with a user, to start a search from a distance in order to verify whether certain objects are located near or inside the vehicle.
