Subroutine 209,tests status of 208, a negative result of said test being a loop to 207; a positive result disabling 191 and 200 via subroutine 218 and returning to 197.
  • a remote control receiver is used for element 180.
  • remote control receiver 180 receives a valid code from a remote transmitter, 180 outputs a valid code voltage via 181 to 182. If invalid codes are received 180 will ignore subsequent code inputs for a period of time, thus foiling the attempts made by a code scanning device.
  • 214 tests for a valid code condition. A positive response enables 216.
  • Ignition circuit status i.e., engine running, via conductor 194, is monitored by circuit 183.
  • Subroutine 220 monitors status from 183 via conductor 184. Engine running status is verified by subroutine 217. If the result of the test is positive, the program continues; if the result is negative, subroutine 217 returns to software timer 215, where a time-out condition occurs, and the program returns to 197.
  • Maintenance mode of operation can be entered into and exited from only when the engine is running.
  • 180 When said remote control receiver 180 receives a valid code from a remote transmitter, 180 outputs a valid code voltage via 181 to 182. 214 tests for a valid code condition while 217 tests for a engine running condition. A positive response enables 216 and 218. If a corresponding discreet code input occurs at 214, said light emitting diode 197 stops flashing, relay 188 is enabled by 182 via conductor 189 making starter solenoid circuit 190 indicated by an encircled "S", operable via conductor 195.
  • Ignition circuit 185 via conductor 194 is monitored by circuit 183, element 182 subroutine 220 monitors status from 183 via conductor 184 to test engine running status by subroutine 217. If subroutine 221 determines engine is stopped, program returns to 197 and loops, waiting for a valid code input at 180.

Abstract

Un dispositif (1) antivol et anti-détournement de voitures comprend plusieurs boîtiers (3) conteneurs métalliques, de forme généralement cylindrique, renfermant un tableau de connexions imprimé (111), un élément commutateur (188) et un microcontrôleur (72) de lecteur de codes à barres numérique. Le boîtier métallique (3) est fixé sur les bornes électriques (139) d'un solénoïde (44) de démarreur ou d'un moteur de démarrage (29) d'automobile. Le dispositif (1) empêche l'allumage trafiqué du circuit d'allumage au niveau des bornes électriques (139) du solénoïde. Le dispositif (1) utilise un petit transpondeur (100) à signaux numériques codés HF de faible puissance, une antenne (102) et un lecteur (182) pour décoder les codes numériques renvoyés par le transpondeur. Le fonctionnement automatique du système anti-détournement de voitures est déclenché par le positionnement des contacts électriques d'un contacteur (85) de porte.
