【発明の名称】遠隔アクセス制御方法および装置
Document Type and Number:
Japanese Patent JP2003500957
Kind Code:
A
Abstract:
Remote access (for example to a motor vehicle) is controlled with a configuration having a transceiver unit. The transceiver unit outputs an interrogation signal which activates all available access code transmitters at the same time, and all the access code transmitters which receive this interrogation signal then transmit their specific access code signals, essentially at the same time. The transceiver unit separates the access code signals received at the same time on the basis of a characteristic applied to them.
