Electric circuit for an access control and for an immobilizer of a vehicle and method for calibrating an antenna driver
摘要：
An electric circuit for controlling the access and immobilizing a vehicle has a first antenna driver (12) for driving a first antenna (19) for emitting a signal (100) in the event of identification of an ID transmitter (3) for access control of a vehicle. A second antenna driver (24) is provided for driving a second antenna (21) for emitting a signal (104) in the event of identification of an ID transmitter (3) for the immobilizer of the vehicle. In addition, the electric circuit has a receiver device (14) for receiving a signal captured by an antenna (21) for the identification of an ID transmitter (3) for the immobilizer. The first antenna driver (12) and the receiver device (14) are commonly integrated into a semiconductor chip (1).
摘要（中）：

用于控制车辆的通行和固定的电路具有第一天线驱动器（12），用于在ID发送器（3）的识别的情况下驱动用于发出信号（100）的第一天线（19），用于访问控制 一辆车。 提供第二天线驱动器（24），用于在识别用于车辆的防盗装置的ID发送器（3）的情况下驱动用于发出信号（104）的第二天线（21）。 另外，电路具有接收装置（14），用于接收由天线（21）捕获的信号，用于识别用于防盗器的ID发送器（3）。 第一天线驱动器（12）和接收器装置（14）通常集成到半导体芯片（1）中。
