Remote-controlled access control device, in particular for a motor vehicle, and portable transponder which is configured for it
First Claim
1. A remote-controlled access control device, comprising:
- a triggering device;
a stationary transceiver device connected to said triggering device, said stationary transceiver device transmitting an interrogation code signal when said triggering device is activated;
a portable transponder configured to receive the interrogation code signal and having a manually activatable activation element, said portable transponder generating a code signal and transmitting, together with the code signal, a given information indicating whether the code signal is generated in response to the interrogation code signal or in response to said activation element being activated; and
said stationary transceiver device receiving the given information together with the code signal and generating an unlocking signal based on an evaluation of the given information and based on a comparison of the code signal with an internal reference code signal.

Abstract
A remote-controlled access control device includes a stationary transceiver device with a triggering device and a portable transponder. The stationary transceiver device transmits an interrogation code signal in response to the triggering device being activated. The portable transponder receives the interrogation code signal and has a manually activatable activation element. The portable transponder generates a code signal and transmits, together with the code signal, information indicating whether the code signal is generated in response to the interrogation code signal or in response to the activation element being activated. The stationary transceiver device receives the information together with the code signal and generates an unlocking signal based on an evaluation of the code signal with the information indicating whether the code signal is generated in response to the interrogation code signal or in response to the activation element being activated.
