    • In a procedure for the provision of access authorization for an engine-driven vehicle, if there is an operator request for the provision of access authorization to an engine-driven vehicle, a bidirectional signal transmission using encoded transmission signals and an electronic key will be effected. From transmission units located on or in the vehicle, vehicle signals will be transmitted to the electronic key, and, from the electronic key, key signals will be returned as echo signals to the respective transmission units. The time difference between the vehicle signal and the key signals will be determined and evaluated. The position of the electronic key in relation to the vehicle will be determined by means of successive bidirectional signal transmissions between at least two transmission units and the electronic key as well as by evaluating the time differences; having determined the actual key position, a decision on access authorization to the vehicle will be made.
    • 在提供发动机驱动车辆的通行授权的程序中,如果操作人员要求向发动机驱动的车辆提供存取授权,将使用编码的传输信号和电子钥匙进行双向信号传输 。 来自位于车辆上或车辆上的传动单​​元将车辆信号发送到电子钥匙,并且从电子钥匙将键信号作为回波信号返回给各个传动单元。 将确定和评估车辆信号与钥匙信号之间的时间差。 电子钥匙相对于车辆的位置将通过至少两个传输单元和电子钥匙之间的连续双向信号传输以及通过评估时间差来确定; 确定了实际的关键位置,将对车辆的访问授权作出决定。
