A MISFUELLING PROTECTION SYSTEM FOR A VEHICLE

摘要

A misfuelling protection system when fuelling a vehicle from a fuel delivery pump (30) of the type typically used for supply of fuel to a vehicle on a garage forecourt and which comprises a transceiver (23) (123) on the fuel pump, and a transponder (14) on the vehicle. The transceiver (23) transmits a request signal R1 to the transponder (14) and receives a response signal Rc with a plurality of anticipated response signals stored therein and dependant upon the response received, the control unit (26) activates a misfuelling protection system which either prevents the pump from delivering fuel to the vehicle and/or operates a warning device to alert the pump user to a potential misfuelling incident.
