Title: Direction indicator control circuit
IPC: B60Q1/38
Filed: 1973-03-22
Abstract: 1466263 Road traffic signals on vehicles LUCAS ELECTRICAL Ltd 22 Feb 1974 [22 March 1973] 13785/73 Heading G4Q  Road vehicle direction-indicators are operated by associated electromagnetic relays 24, 44 energized via push-buttons 10, 11 and semiconductor switching means cause automatic cancellation when the steering wheel is returned to its centre position. In the embodiment the steering wheel carries a permanent magnet 21 co-operating with reed switches 19 to 22. (A photo-electric alternative, not particularly described, may be utilized). In operation, assuming a left turn, the driver depresses switch 10 thereby energizing relay coil 24 a contact 29 of which maintains coil energization on release of switch 10 and a contact 30 connects supply through flasher unit 32 to the L.H. directionindicator lamps. Pilot lamp 14 will be deenergized and pilot lamp 16 flashes. As the steering wheel turns to the left to actuate reed switch 19 an electrolytic capacitor 38a charges; as the steering wheel is returned to its central position, ensuing closure of reed switch 20 causes capacitor 41 to charge thereby turning on transistor 33 and turning off transistor 34, the latter resulting in transistor 25 turning off to de-energize coil 24. If the driver depresses switch 10 to indicate a lane shift to the left and the steering wheel does not go as far as closure of switch 19 the direction-indicator lamps do not automatically cancel and a switch 12 is closed manually to turn off transistor 25 and de-energize coil 24. Switches 11, 13 &c. are utilized in a like manner for a right-hand shift. Diodes 23, 43 protect the circuit against ignition transients and diodes 62 63 cause de-energization of an energized relay coil if the manual switch associated with the other relay coil is operated.
