Electrical system with sharing control for motor vehicles

The invention is in the field of vehicle equipment and is to be applied in the design of a vehicle electrical system, in which the consumers are connected using a multiplex control by means of switching elements of a two-wire power line.

A known on-board network of this kind is equipped with a two-pair cable, wherein a first pair of opposite flat gegen¬ to power conductors and a second pair of opposing circular signal conductors are arranged in a common insulating sheath. A central multiplex transmission station is connected to the Signallei¬ tern; a battery is connected to the power conductors. Consumers in the form of lamps, motors, etc., and actuators and switches are each connected to gen Endeinrichtun-, which in turn both to both the

Signal conductors as are connected to the two power conductors of zwei¬ pair cable. is used to connect the Verbrau¬ cher and switches to the two-pair cable in each case a terminal unit having a two-piece housing body and blade-like connecting elements in this housing body. The housing body further includes a circuit board having a printed circuit to accommodate circuit components such as a chip with an IC and a switching member for closing or opening of the current path to the respective consumer. The housing body is provided with a female connector further, which serves to receive a Stek¬ kers, which in turn is arranged at one end of an electric wire connected to the respective associated consumers (EP-A1-0 283 013 / DE 38 83 032 T2; EP Al 0 283 012). In another known vehicle electrical system of this type a two-core cable with two conductors is different Quer¬ section used, wherein the conductor of smaller cross section for signal transmission and the conductor of larger cross section for energy transmission is used. The two conductors form in each case the send a signal or energy-circle, while the return path is formed from the chassis of the vehicle. Even in this electrical system spezi¬ elle transmission units for connection of the consumer is provided which contact one hand, the signal and power conductors and the anderer¬ hand, each serving, at the one end of a supply line to the respective consumer, actuator or for receiving a plug is arranged sensor (US-A 3,651,454).

To sierungsebene in plant and machine on the bottom Automati¬ to reduce the amount of wiring, is also a bus system is known which operates with a two-core cable that transmits both data / signals as well as energy. Both the master station the data transmission and the power source to the two-wire line are connected to the master station using a corresponding inductive or capacitive Ankoppeisehaltung. For the connection of sensors and actuators to the bus line special application modules by means of the cutting / clamping technique are further connected, which act as a slave and to the connection lines of individual sensors and Aktuato¬ ren be connected can be plugged. Unless the slave function is integrated into a sensor or actuator, it can also be connected directly to the bus line (DE-Z "Flexible Automation" 3/93, pages 56 to 58).

Starting with an electrical system for motor vehicles with the features of the preamble of claim 1 of the invention has the object to further simplify the design of the electrical system and to ensure safe operation of the consumer. To achieve this object there is provided according to the invention that the control members are coupled to the power line that the branch lines each terminating in a connectable to the respective consumer plug and that the Steuer¬ membered each switch or load from a Sen¬ / receiver divided for communication with the other Steuer¬, further comprised of a switching electronics for controlling the switching member and of a device for monitoring the current flowing to the load current is.

In such a configuration of the electrical system, only a single two-wire power line is used for power distribution used having optionally individual, in a star shape in the different areas of the motor vehicle (engine space, Fahr¬ guest room right passenger compartment on the left) extending portions, and at the same time for the communication of the transmits switch and consumers required signals. The energy supply to the consumers takes place in each case via a branch line whose electrical cross-section the

Energy consumption of the load may be adapted. This branch line, which is connected by means of a fastremovable Ab¬ branch element in the form of an insulation displacement connector to the power line, in each case ends in a plug contact, which is brauchers connectable to the respective mating contact of the method. The fast-mounted Abzweige¬ is lement designed as a "smart connector", which in addition to the cutting contacts and at least a coupled to the power line control element and the respective gen consumers associated switching element, such as a power transistor or a relay, contains. In addition, incorporating "smart connector" a Über¬ monitoring device for the current flowing through the branch line to the load current. Such Überwachungsein- direction allows the first place the practical use of wiring systems as known from the aforementioned prior 97/02965 PCΪ7DE96 / 01312

4 are known technique. Without such Überwachungseinrich¬ processing individual consumers and their supply lines in the region of a central fuse box should be individually protected as it has been customary with the known cabling requirements in automotive electrical systems. Pursuant to

Invention provided electronic current monitoring unmit¬ telbar on the spur of the consumer has, however, together with the multiplex control, the ability to control the switching element of individual consumers in case of a short circuit or other failure, the

off consumers together with its branch line to issue an error message and open the switching element after the repair again. - The output of the hier¬ used in current monitoring device on the one hand coupled to the drive circuit of the switch member and acts on the other one to the input of the transmitter.

One embodiment of the new on-board network is shown in Figures 1 and 2. FIG. Here, Figure 1 shows the overall architecture of the electrical system and

2 shows the circuit construction in the region of an intelligent connector.

According to Figure 1, a energy is gieleitung 1 used for the construction of the electrical system, which is designed with two conductors and which is substantially H-shape laid in a motor vehicle, particularly in a passenger car. To the power line 1, the battery 2 is connected via a connecting element. 7 Via further connecting elements 8, two intelligent switching units 3 are connected to the power line, the Siche¬ conclusions contain relay and a control electronics and which each have a central device 4 is associated with the diagnosis of the vehicle electrical system.

At various points of the power line 1 intelli¬ gent connector 9 are arranged, of which 5 each perform one or more branch lines to connectors. 6 The connectors 6 serve for connection of the branch lines of which are arranged on the periphery of the motor vehicle Ver¬ consumers and / or switches, such as lamps, flashing lights and relay, for example for locking of door locks. When the plugs 6, there may be two or multi-pole connector. Such plugs can be constructed, for example according to European Patent Application 0,597,388.

The intelligent connector are equipped with IDCs for contacting the power line 1 and for contacting the connection lines branches off. 5 The circuit design of such a connector is shown in FIG 2. Then, the wires 11 and 12 of the power line 1 at the points 91 and 92 are contacted, while the cores 51 and 52 of the branch line 5 are kontak¬ advantage at the points 93 and 94th Between two inner current paths 97 and 98, an integrated circuit 95 is arranged, which contains a Sen¬ / receiver for communication with the other intelligent connectors and the intelligent switching units 3, an associated signal processing and switching electronics for controlling the switching element 96, Schalt¬ its contact in the current path 97 is looped. With an electronic current meter A, the current flowing to the load current can continue to be measured; the zugehö¬ membered evaluation logic is arranged in the integrated circuit 95th
