Definitions
- the invention relates to an electrical system of a motor vehicle with the features of the preamble of claim 1.
- Such an electrical system is, for. B. from the NDI reports from 2001 on p. 1 109, known.
- There are several central electronics or signal processing modules are provided, which are connected to different user groups via bus connections. These electronics also have fuse boxes mounted separately on their box, which are used for protection and power distribution.
- the protected path is looped through the central electronics, since the further current distribution takes place in the downstream central electronics. This requires additional plug contacts, which means that two devices require a lot of installation space.
- the cables are often routed from the fuse box through grommets through the partitions to the central electronics, which is complex and also lets sound through, for example from the engine compartment, since the fuse box is usually located in the engine compartment. From the fuse box and the central electronics - usually if two are used in the vehicle - the line bundle goes wildly structured to the individual consumers.
- the object of the invention is to avoid these disadvantages mentioned.
- 3a to 3e show a system of possible arrangements of the central electronics
- a normal car is shown with a partition 1 at the front and a partition 2 at the rear.
- SP boxes integrated fuse box
- Current distribution is understood to mean, for example, the control of a motor, signal distribution is the reading in of switches, sensor and bus signals.
- conventional fuses are not used to protect the current paths, but rather Switches (mosfets or relays) additionally with a current measuring element, e.g. a shunt.
- a reversible fuse eg a so-called polyswitch
- the box of such central electronics with the integrated signal and power processing including fuses is referred to below as the Sp (signal and power) box.
- the Sp box has electrical connections on both sides.
- plugs 5 and 6 are provided in FIG. 1.
- the bushings are sealed so that one wall of the box 3 is placed tightly on the partition 1 from the passenger compartment.
- This wall opposite the partition 1 has an opening la for the passage of the connecting cables going to the consumers in the engine compartment.
- the connections of these cables to the connections of the box 3 are designed as plugs.
- These plugs 5 are connected to individual, relatively short cable sets, which are also connected to plugs at the other end.
- a plug 7 is connected to the electric wiper and the window heater; the connector 8 is connected to the ABS control unit and switches in the central area of the engine compartment, connector 9 with the engine and transmission control, connector 10 with front lights, headlamp leveling and headlight cleaning, connector 1 1 with consumers in the lower part of the engine compartment, such as Fresh air blowers and heating valves.
- the wiring harnesses are preferably connected directly to the box of the central electronics, for example. by means of insulation displacement technology 12.
- the mating connectors, eg 13 are connected to the roof module, 14 to the door consumers, 15 to the center console and 16 to the cockpit consumers such as the instrument cluster, heating / air conditioning control, etc.
- a line leads from the generator 17 to an electrical energy store, preferably an Ultra Cap 1 8. borrowed great benefits when starting and for recuperation.
- the Ultra Cap is preferably for temperature reasons and the short line to the generator is therefore located in the footwell.
- the generator 17 is preferably an integrated starter generator.
- the rear part of the consumers and the rear central electronics are supplied via a line set 19. This line can be continued to a backup battery 20 in the trunk.
- Similar to the SP-Box 3 at the front, 4 cables are attached to the rear box or connected to it by plugs, the other end 21 to the trunk 22, to devices such as navigation, telephone, sound and 23 to lights and 24 to the rear doors to lead.
- the most striking feature here are the relatively short cable sets. Due to the SP boxes 3 and 4 on the partitions 1 and 2, no threading of lines and no use of grommets is necessary. The short cable sets with a simple structure can be largely automatically manufactured.
- Fig. 2 shows the structure of a station wagon, in which no partition is inserted at the rear.
- the SP-Box 4 is installed in the rear of the vehicle with the same wiring harness structure to the consumers as in the front.
- Fig. 3b two SP boxes 31, 3r, front, left and right; in both cases the SP box is connected to the battery 25 and the generator G;
- FIG. 3c shows an SP box 3 at the front and two SP boxes 4r and 41 at the rear; here two energy stores, a starter battery 25 and a supply battery 25a are provided, which are electrically connected to the associated SP boxes.
- An ultra cap can also be used instead of the battery 25.
- the generator G is usually connected to the front energy store 25.
- Fig. 3d two SP boxes in the front and one SP box in the back;
- Fig. 3 e two SP boxes in the front and two SP boxes in the back.
- a second energy store can additionally be connected to one of the SP boxes
- Light control headlight range and possibly cornering light control
- the evaluation of the signals from the tire pressure sensors transmitted by radio (HF) is particularly favorable, since the SP boxes at the front and rear are only to be provided internally or externally with an antenna at the rear.
- the MC evaluates the signals. Communication with the other SP boxes takes place via a bus connection.
- the positioning of the functions in the individual boxes essentially depends on the proximity to the consumer and the utilization of the plug, interface and the microcontroller (s) provided in the box.
- Fig. 4 shows the block diagram of a box, for example the front left 31 in the basic structure.
- the SP-Box 41 is supplied at the rear left, the door at the front left and the seat via a relay 26 and a shunt 27.
- the current-proportional voltage signal is fed via line 28 to the MC 35.
- the relay 29 with a shunt 33 supplies some power output stages for, for example, the wiper control 30, the washer fluid heater 31 and the washer fluid pump 32.
- the current is measured via shunt 33 and a measuring line 34 and plausible in the microcomputer 35 (MC) with the load connected via the output stages compared. In the event of implausibility, the error is reported to a diagnostic system or shown on a display.
- the control line from the MC 35 is only indicated here at the line output stages 48.
- a polyswitch 36 is also used to supply power to the small one via the power line, which leads to the final stages
- Bus node e.g. based on LIN 41.
- This bus node contains e.g. as an alternative to the above-mentioned embodiment, tire pressure control receiver 37. Since this is arranged in the vicinity of the shock absorber, to relieve the cable set, e.g. Switch signals, e.g. Brake pad wear 38 and windscreen washer fluid level 39 read in.
- Other LIN nodes are the sensors of the parking aid 40, which are connected to the bus line 41.
- the Polyswitch 36 blocks and this is recognized in the MC 35 via shunt 33. Also e.g. a through-stage of an output stage is recognizable, again through a plausibility comparison. In this rare case, the entire branch is switched off when the short-circuit current is high. Partial short circuits can also be detected.
- the relay 29 opens and the quiescent current is then 0 to relieve the battery, so that faulty leakage currents do not cause an empty battery 43.
- the current from and to the battery 43 can be measured via the current measuring element 42 and the current from the generator to the MC 35 via a element 44.
- the MC 35 is still connected to CAN B 45 and CAN C 46, which is necessary for the gateway function.
- 3 relays, power amplifiers and / or polyswitches are provided in the SP-Box.
- Mosfets can also be used instead of the relays.
- the advantages of the relays are: reverse polarity protection;
- the box drawn is protected against polarity reversal, the MC is protected by a diode 47.
- the design according to the invention can also be used in a multi-voltage electrical system, the consumers of which are supplied by a generator and in principle by one or two batteries connected in parallel.
- the central electronics in the SP boxes can be designed so that one SP box has the master function in the software structure and the remaining SP boxes have slave functions, i.e. they only accept signals and control consumers.
- One slave box handles the processing.
- the slave boxes can be designed so that if the master SP box fails, they start an emergency program for minimal function.
- FIG. 5 the partition 1 'is shown in front.
- the SP-Box 3 ' is in the footwell of the front passenger compartment, but in order to achieve short connections as close as possible to the partition 1'.
- the partition 1 ' has an opening 1', into which a separation point 3a is inserted on the one hand for the connecting cable 3b to the consumers on the motor side and on the other hand 3c to the SP box 3 '.
- the connecting cables 3b and / or 3c can be connected to the separation point 3a by means of plugs. From the box 3 'also cables 3d go to the consumers and / or switches in the passenger compartment ah. In this case . all connections to box 3 'are provided on one side in box 3'.
