Current route information about a traffic situation and/or the state of the route itself is made available. A communication link to a peer-to-peer network is set up by a communication device of a motor vehicle, and the motor vehicle is signed on to said peer-to-peer network as a subscriber of the peer-to-peer network, with the result that a communication address of the motor vehicle can be determined by at least one other subscriber of the peer-to-peer network. Furthermore, in each case an interrogation relating to the route information is received by the communication device from the at least one other subscriber. The route information itself is determined by a sensing device of the motor vehicle and is then transmitted to the interrogating subscriber by the communication device.

Method for making available route information by means of at least one motor vehicle

Method of controlling the electric heating of a catalytic converter

In the case of an electrical wiring for a motor vehicle having a primary system which includes a voltage-controlled generator, a primary energy accumulator as well as at least one primary energy consuming device, and having a paralleled secondary system which includes a secondary energy accumulator as well as at least one secondary energy consuming device, the secondary system includes a control unit with a controllable resistor connected to the generator. The control unit monitors the charge condition of the secondary energy accumulator. As a function of the currently determined charge condition of the secondary energy accumulator, the control unit, on the one hand, controls the controllable resistor in such a manner that, during the charging of the secondary energy accumulator, the primary system is not overloaded. Furthermore, the control unit connects and disconnects the secondary energy consuming device or devices in such a manner that, during the discharging of the secondary energy accumulator, there is no falling below a predetermined residual charge value.
