Definitions

  • the invention relates to an electrical system of a motor vehicle with the features of the preamble of claim 1.
  • ripple count method has been used instead of Hall sensors, in which the current peaks generated by the commutator of the motor are evaluated.
  • the number of functions to be performed is high for the driver's door and medium for the front passenger door, but low for the rear doors.
  • small bus nodes are used in the exterior mirror, the door lock and the operating switches, which are connected to the central control unit, e.g. B. a separate central door control unit, communicate via a bus connection.
  • the central control unit e.g. B. a separate central door control unit
  • these small bus nodes are problematic if too few lines are saved in the base vehicle and only enough lines are saved in the maximum equipped vehicle.
  • the window lift functions on the rear doors are often processed by a central control unit, in which a central MC takes care of the control; this MC can then be used for both rear doors.
  • many individual lines for the window regulator, the switches and the lights lead to the central control unit, which is usually positioned under the seat or in the trunk.
  • a master / slave structure can also be introduced, in which these smaller bus nodes (slave) only receive signals and thereby trigger consumers, and the computing power is essentially shifted to the master.
  • the object of the invention is to provide inexpensive architecture for modules in motor vehicles, in particular for the door modules find which reduces the number of lines required with inexpensive bus nodes and which is preferably additionally flexible for different functionalities.
  • Figure 1 shows the basic idea of the invention.
  • Fig. 1 describes the front door 1 with an outside mirror 2, a door lock 3, operating switches 4, lights 5 and 5a, a window motor 6 with its position transmitter 6a and with a control unit 7 designed as a bus node for this door module.
  • the number of lines actually required is indicated in each case in the vicinity of the dash on the line shown.
  • the position transmitter 6a is connected to the door control unit 7 and receives its voltage supply from it.
  • This control unit 7 communicates with consumers 2, 3 and 4 via bus nodes 2 3 and 4 z.
  • B. LIN the bus nodes are each marked with a rectangle with a cross in the drawing. The description so far corresponds to the state of the art, as was also published in the conference mentioned above.
  • a central vehicle electrical system control unit 9 This is preferably designed as an SP box or PSD box (power signal distribution box), as is the case here in the earlier patent applications 102 43 970.2 and 103 00 464.5.
  • Connection 12 of the single-wire bus also leads to this device.
  • This bus line 12 can also be connected to further bus nodes 13 his.
  • the power supply for the door control unit 7 is not shown, but is included in the three lines to the control unit 9.
  • the control unit 9 contains an MC 10, the interface of which is not described separately here.
  • This structuring relieves the MC of the control device 7, which is not shown, very much and can be constructed as an inexpensive slave, the associated master being accommodated in the control device 9.
  • the functions for the exterior mirror 2, the door lock 3, the control switch 4 and the lights 5 and 5a are simple arithmetic operations, the transmission of which, for. B. via LIN bus from the master in control unit 9 to control unit 7.
  • Symbols PIN 14 are underlaid on the control unit 7, which can be used for variants of the door functions, as described with reference to FIG. 2.
  • FIG. 1 Here is a simplified door lock 3a with four connecting lines. In comparison to the LIN node of FIG. 1, only one line would be saved, so that this does not pay off. The same applies to the outside mirror 2a and the operating switches 4a. With this reduced range of functions, a central door control unit 7a is used which does not control an additional LIN node.
  • the window motor 6a is controlled via the external central control unit 9a with the functions described in FIG. 1.
  • the position encoder is missing in this version.
  • the position is e.g. determined using the well-known ripple count method.
  • the shunt required for this is shown in FIG. 2 and designated 15. This cost-saving method can also be used in the exemplary embodiment in FIG. 1.
  • control unit 7a can be made small and flat and can be optimized technologically and in packaging, e.g. B. in chip-on-silicon technology, since space-consuming or area-consuming relays or large H-bridges do not have to be accommodated.
  • a master could sit in front on the left and right, which is the controls respective window motors on one side of the vehicle. This would allow the rear SP boxes to be designed as slaves.
  • the door bus node 7b On the window lift motor, which is indicated by the box 17, or to integrate both into one another. An additional supply line for the bus node 7b can thus be saved when two diodes 20 are used.
  • the lines 19 can be configured in flat conductors or foil technology. This also applies to the connection of the remaining consumers in accordance with FIG. 3.
  • this chip can be expanded as MC-ASIC for the bus node, including the integration of the diodes.
  • the signal line of the Hall sensor is fed to the central control unit as in FIG. 1.
  • SP boxes were mentioned above.
  • switching devices for the fuse and distributor function are integrated in these, which preferably protect all low and high current paths to the adjacent consumers in the SP box.
  • the outputs of the connecting cables are preferably protected by switches (mosfets and / or relays) and / or reversible fuses (polyswitches).

Abstract

Réseau de bord pour un véhicule à moteur, dans lequel les consommateurs sont rassemblés en modules individuels du véhicule, la majorité des consommateurs d'un module étant commandée et / ou réglée via au moins un noeud de bus connecté à un appareil de commande central par l'intermédiaire d'une liaison de bus. Au moins un consommateur appartenant au module, de préférence un consommateur de courant fort, est commandé et / ou réglé directement par l'appareil de commande central.
