摘要:
A device, system and method for an update system for updating a digital map for a vehicle. The update data is sent from a control center via a satellite navigation system to the individual receivers. The update data is received by the receivers in parallel with the position data from the satellites. For this purpose, a subchannel is provided. This allows large portions of the worldwide population to be supplied with the update data.

A method for checking communication messages in vehicle-to-environment communication, a communication message being received and evaluated, and to a receiver suitable for carrying out the method. In order to check a communication message, a feature obtained from the content of the communication message is compared to a feature that corresponds to said feature, the corresponding feature being obtained by a sensory system that is independent of the vehicle-to-environment communication.
摘要:
A method for the communication of a vehicle with at least one further vehicle and/or for the communication of a vehicle with an infrastructure device (C2X communication), wherein the communication serves to transmit at least one information item for application in a driver assistance system and/or a safety system of the vehicle. In order to ensure good safety and reliability of the driver assistance system or safety system in the case of low market penetration of C2X communication, the at least one information item is transmitted via a first communication channel and/or via a second communication channel in dependence on its nature, wherein the first communication channel has a longer latency period than the second communication channel. The invention also describes a corresponding communication device, a corresponding driver assistance system or a corresponding safety system, a corresponding vehicle, a program element and a computer-readable medium.
摘要:
A method and a device for triggering an emergency call in a vehicle equipped with an airbag. The device can be retrofitted in a vehicle equipped with an airbag to provide an emergency system which, in the event of an airbag being triggered, sends an emergency call (Ecall) to a suitable emergency call center in order to initiate auxiliary measures as may be necessary.
摘要:
A vehicle antenna unit for participation in vehicle-to-surroundings communication in accordance with the DSRC or ITS-G5 standard having an adhoc network antenna for sending and receiving in the region of 5.9 GHz, having a satellite antenna for receiving satellite locating signals and having driver elements, which are set up to send, bit by bit, and/or to receive data with the adhoc network antenna and the satellite antenna, and having a computation unit for conditioning the data. In order to allow the vehicle to participate in the vehicle-to-surroundings communication, the computation unit is set up to evaluate the satellite locating signals and for the purpose of independent participation by the vehicle antenna unit in the vehicle-to-surroundings communication.
摘要:
The invention relates to a vehicle unit in a vehicle, including at least one multimedia control unit and at least one safety control unit for controlling multimedia and safety functions, wherein the vehicle unit is provided as a switching unit between the multimedia control unit and the safety control unit, and wherein the switching unit processes the data received from the multimedia control unit and makes the data available to the safety control unit. The switching unit also transmits data received from the safety control unit to the multimedia control unit. Furthermore, the switching unit has a safety level which is higher than that of the multimedia control unit and lower than that the safety control unit.
摘要:
Methods and an appropriately setup communication unit for positioning in vehicle-to-surroundings communication are described, wherein the method involves a first sensor (S1) of a first communication subscriber using a transmission and reception unit to emit a challenge pulse, to which a transmission and reception unit of a second sensor (S2) of a second communication subscriber responds with a response pulse. The response pulse is received and evaluated by the first sensor (S1) and positioning is performed. In order to achieve reliable cooperative sensor communication, the transmission and reception units of the first and second sensors (S1, S2) use a frequency band (SCH2) which is reserved for vehicle-oriented safety applications.
摘要:
A method and system for ascertaining at least one traffic-related local information item for a vehicle includes a reception device in a radio system to receive sent data from a radio system in at least one other vehicle in the vicinity of the one vehicle as defined by the reception range of the reception device. The reception device is configured for the vehicle-internal capture and evaluation of data for at least one operating variable from the one vehicle. The traffic-related local information item is ascertained from the received data from the other vehicle.
