摘要:
A keyless access control device and method for a vehicle having a door and a door handle includes transmitting a code from a transceiver while a cover covers the door handle to prevent a user from actuating the door handle. A transponder of the user transmits an answer to the transceiver upon receipt of the code. The answer is checked to conduct a preliminary verification of whether the user is authorized to access the vehicle. The cover uncovers the door handle if the preliminary verification indicates that the user is authorized to access the vehicle. A bidirectional question and answer dialog takes place between the transceiver and the transponder to conduct a final verification of whether the user is authorized to access the vehicle upon the user actuating the door handle. The door is unlocked if the final verification is indicative of the user having access to the vehicle.
