Embodiment Construction

[0019] figure 1 An embodiment according to the invention of a communication system is shown, which is designed to participate in a chained ad-hoc wireless network between motor vehicles. The communication system has a control unit 1 . The sending / receiving unit 2 is connected with the control unit 1 , and the sending / receiving unit receives and sends wireless signals through the antenna 3 . In addition, an electronic compass 4 is connected via the control unit 1 , which transmits to the control unit 1 information on the orientation of the vehicle with reference to north. In this case, the orientation refers to the longitudinal direction of the motor vehicle, which extends from the front end to the rear end of the motor vehicle and can also be represented by a vector. The control unit 1 is designed to evaluate the orientation of the motor vehicle with reference to the orientation of at least one other motor vehicle received via the transmitter / receiver unit 2 . In this case,...

Abstract

The invention relates to a communication system in a motor vehicle which is designed to participate in a chain-like ad-hoc radio network between motor vehicles (car0 to car5) and has a control unit (1) and a transmission / reception unit (2) connected to the control unit (1). To set up a radio network which is based on direction of travel, it is proposed that the communication system have means, connected to the control unit (1), for determining an orientation of the motor vehicle relative to a reference direction (N) and that the control unit (1) be designed to assess the orientation of the motor vehicle in respect of an orientation of at least one other motor vehicle which is received via the transmission / reception unit (2).

Description

technical field [0001] The invention relates to a communication system for a motor vehicle, which is designed to participate in a chained ad-hoc wireless network between motor vehicles and has a control unit and a transmitting / receiving unit connected to the control unit. Furthermore, the invention relates to a method for setting up a wireless chained ad-hoc wireless network between motor vehicles. Background technique [0002] An ad-hoc wireless network involving multiple vehicles is also known as "vehicle-to-vehicle communication". In this wireless network, motor vehicles can exchange information with each other. This information can, for example, be information about danger points, road conditions or also about approaching motor vehicles with right-of-way or the like. [0003] Each participating motor vehicle has a transmit / receive unit with a low transmit power. The transmit power is determined, for example, in such a way that only connections from neighboring motor v...
