Embodiment Construction

[0034] figure 1 A motor vehicle 1 is shown, which can be, for example, a motor vehicle, in particular a sedan. The figure shows a mobile radio module 2 , an emergency call control device 3 , a switching device 4 , an antenna 5 which can be arranged on the roof 6 of the motor vehicle 1 and which can be arranged, for example, in the vehicle interior 8 of the motor vehicle 1 Antenna 7. Antenna 7 can be integrated, for example, in the dashboard of motor vehicle 1 . The mobile radio module 2 can be provided, for example, by an infotainment system. The mobile radio module 2 can be a mobile phone, which can be used by the user (not shown) of the motor vehicle 1 to make telephone calls. The mobile radio module 2 can also be designed or configured as a modem for an Internet connection. The mobile radio module 2 can comprise, for example, a GSM module (GSM: Global System for Mobile Communications), a UMTS module (UMTS: Universal Mobile Telecommunications System) or an LTE module (LT...

Abstract

The invention relates to a switching device (4) for alternately connecting a mobile radio module (2) and an emergency call control device (3) to an antenna (5), the switching device having a first signal input (10) , a second signal input terminal (12), an antenna connection terminal (14) and a switching device (15), the switching device is configured to switch between the first switching state (S1) and the second switching state according to at least one switching signal (22) Switching between states (S2), wherein in the first switching state (S1) only the first signal input terminal (10) is electrically connected to the antenna connection terminal (14), and in the second switching state (S2) only the second The signal input end (12) is electrically connected with the antenna connection end (14). The connected transmitting device shall not diagnose a loss of coupling to the antenna connection as a fault. In the second switching state (S2) or in both switching states (S1, S2), the signal input (12, 10) decoupled from the antenna connection (14) is electrically connected to the terminal via the switching device (15) The device (18), the terminal device (18), emulates an antenna at a signal input (12, 10) connected thereto.

Description

technical field [0001] The invention relates to a switching device for alternately connecting mobile radio modules and emergency call control devices to a common antenna. The antenna can thus be used by the mobile radio module and, if necessary, coupled to the emergency call control device. Background technique [0002] An emergency call (emergency-call in English or E-call for short) can be made by means of the emergency call control device. If the motor vehicle is involved in an accident, the emergency call control device automatically triggers such an emergency call. The emergency call control device can be activated, for example, by a trigger signal of the crash sensor system. By means of an emergency call, for example, information about the current position of the motor vehicle can be transmitted to a dispatch center. Furthermore, a telephone connection between the control center and the passenger compartment of the motor vehicle can be provided. Thus, persons locat...
