Definitions

  • the wiring system currently employed for controlling the above electrical devices comprises a number of cables, each controlling a specific device.
  • Such a system obviously involves numerous drawbacks, such as: complex routing of cable bundles; numerous electrical connections; fault finding difficulties; and complex system testing during and/or after assembly to the vehicle.
  • a system for controlling a number of automotive electrical devices comprising at least an electric operating member, and said system comprising at least a central processing unit and at least a cable for electrically connecting said central processing unit to said devices; characterised by the fact that said devices comprise a specific electronic control block.
  • Number 1 in Fig.l indicates a car having two front doors 2, 2' and two rear doors 3, 3' shown in the open position. Close to the dashpanel 4, there is housed a central processing unit 5 comprising a microprocessor 6 from which originate respective cables 7, 7' , 8 and 8' , each comprising a first positive supply wire 10, a second wire 11 for transmitting information signals, and a third ground wire 12.
  • a central processing unit 5 comprising a microprocessor 6 from which originate respective cables 7, 7' , 8 and 8' , each comprising a first positive supply wire 10, a second wire 11 for transmitting information signals, and a third ground wire 12.
  • Cables 7 and 7' are connected respectively to front doors 2 and 2', and cables 8 and 8' to rear doors 3 and 3'.
  • respective branches of each said cable provide for connecting a manual push-button control device 14, a device 15 for electrically controlling external rearview mirror 16, a door lock device 17, and a window regulating device 18.
  • Each of said devices shown schematically and numbered 19 in Fig.3, presents a connecting block 20 with three connectors for respective connection to a similar terminal block branch connecting the three wires 10, 11 and 12 of cable 7.
  • the connectors of said block 20 are connected to an electronic block 27 comprising a printed circuit 22 to which are connected a first integrated circuit 23 for electrically supplying the actuating member 24 (e.g. d.c.
  • Said integrated circuits 23 and 25 may conveniently comprise specific logic circuits or a microprocessor, solid-state switches, etc., and may form overcurrent or overvoltage protection circuits, control and diagnostic circuits, etc.
  • said first integrated circuit 23 will be absent, whereas device 15 for electrically controlling external rearview mirror 16 will present more than one actuating member 24, for controlling the various electrical actuating members governing positioning of the mirror reflecting surface, positioning of the mirror body in relation to the door, and supply to the reflecting surface heating members.
  • Data is transmitted between central processing unit 5 and the various devices in asynchronous serial manner, the information units being coded by modulating the duration of a pulse the amplitude of which is constantly equal to the difference in potential of wires 10 and 12, and is conveniently transmitted at low speed, about 1-10 K bit/sec, which in no way interferes with priority safety operation of processing unit 5 and, at the same time, presents device operating response times comparable with or less than the minimum delay discernible by the human eye (about 75 msec).
  • each device provides for fault diagnosis, thus improving driving safety, by informing the driver immediately of any operating faults, and also reducing repair time by indicating the type of fault involved. All of which obviously provides for simplifying both on- and off-line testing.
  • Providing each device with a specific monolithic integrated circuit comprising logic circuits enables changes to be made to the type of operation of each device, by simply changing the specific integrated circuit and the resident program on central processing unit 5.
  • changes may be made to the embodiment described and illustrated herein without, however, departing from the scope of the present invention. For example, changes may be made to the number and location of the devices shown by way of example herein (e.g. each door may also feature an electric locking and/or unlocking device), as well as to the circuit configurations also shown by way of example (e.g. a different number of cables may be used for connecting central processing unit 5 to the various devices).

Abstract

Système de commande de plusieurs dispositifs électriques (14, 15, 17, 18, 28, 28'; 19) sur une voiture (1), en particulier ceux montés sur la porte d'un véhicule (2, 2', 3, 3') et comprenant au moins un lève-vitre (18), un dispositif de fermeture (17) de porte, un dispositif à bouton-poussoir de commande manuelle (14) et un dispositif (15) de commande électrique d'un rétroviseur extérieur (16). Ces dispositifs (14, 15, 17, 18, 28, 28'; 19) comprennent au moins un organe de fonctionnement électrique (24), et ce système comprend au moins une unité de traitement centrale (5) et au moins un câble (7, 7', 8, 8') pour connecter électriquement l'unité de traitement centrale (5) aux dispositifs (14, 15, 17, 18, 28, 28'; 19). Un seul câble de connexion électrique (7, 7', 8, 8') est prévu pour les dispositifs (14, 15, 17, 18) sur chaque porte (2, 2', 3, 3'), le câble étant constitué d'un premier fil électrique (10) pour l'alimentation d'énergie électrique positive, d'un second fil électrique (11) pour transmettre des signaux d'informations, et d'un troisième fil électrique de terre (12). Les signaux d'informations sont transmis par le second fil électrique susmentionné (11) de manière asynchrone et sérielle. Les dispositifs (14, 15, 17, 18, 28, 28'; 19) comprennent un module de commande électronique spécifique (27) ayant au moins un premier circuit intégré (23) pour l'alimentation en courant électrique afin d'actionner l'organe susmentionné (24), ainsi qu'un second circuit intégré (25) pour le traitement des signaux d'informations relatifs au fonctionnement de cet organe.
