Disabled vehicle signalling system
Abstract
Abstract A SYSTEM IS DESCRIBED WHICH WILL ALLOW DISABLED MOTORISTS TO SIGNAL FOR HELP DIRECTLY FROM THE DISABLED VEHICLE BY THE USE OF SUITABLY EQUIPPED PASSING VEHICLES ON LIMITED ACCESS HIGHWAYS. THE SUITABLY EQUIPPED VEHICLES RECEIVE THE DISTRESS MESSAGE FROM A DISABLED VEHICLE AND STORE THAT MESSAGE UNTIL THE VEHICLE REACHES AN INTERROGATOR UNIT LOCATED, FOR EXAMPLE, NEAR AN EXIT OF THE HIGHWAYK. THE INTERROGATOR UNIT ACTS BOTH AS A TRANSMITTER AND A RECEIVER. WHEN A PASSING VEHICLE BEARING A DISTRESS MESSAGE RECEIVES THE INTERROGATION SIGNAL, IT TRANSMITS THE DISTRESS MESSAGE TO THE RECEIVER PORTION OF THE INTERROGATION UNIT FOR APPROPRIATE FURTHER ACTION AND IS ITSELF RESET TO THE ORIGINAL STATE SO THAT THE PROCESS CAN START ALL OVER AGAIN. THIS SIGNALLING SYSTEM CAN ALSO ACCOMMODATE AN ACKNOWLEDGEMENT FEATURE SO THAT THE DISABLED MOTORIST WILL KNOW THAT HIS REQUEST FOR ASSISTANCE HAS ENTERED THE SYSTEM. D R A W I N G
