Abstract: A radio receiver, in particular a vehicle radio receiver, is proposed, which is able to display or output acoustically, traffic news which is contained in digital signals. At least the data memory for the decoding of the digital traffic news and of the display or the output in the correct language is contained on a chip card, which can be inserted into the radio receiver. This makes it possible that, on the one hand, a linguistically adapted output of traffic news is possible, and, on the other hand, in the event of changes in the road network, a simple adaptation without modification of the radio receiver is made possible. Finally, it facilitates the use of the radio receiver worldwide, since the chip card allows regionally specific or country specific local codes to be taken into account.

Abstract: A vehicle and destination guidance system is proposed wherein a destination can be input by entering the destination and the street in clear language into a vehicle device. The vehicle device is in communication with a beacon device in which, in addition to the various destinations, street names and the associated coordinates are stored. On demand by the vehicle device, the beacon device selects the associated destination coordinates and transmits them to the vehicle device. Additional data can be transmitted in the transmitted telegram which, for example, contain traffic information or street maps. The system is also usable for automatic toll deductions.

Abstract: A radio receiver selects incoming traffic messages with respect to their validity for the approximate location of the radio receiver and includes a decoder. The radio receiver uses frequency data and coordinate data transmitted by the transmitters to determine its approximate location, and compares this approximate location to locations contained in the traffic messages. When there is conformity, a conformity signal serves to switch through the location-specific messages contained in the traffic messages to an audio output device.

Abstract: A traffic broadcast receiver with a first memory (16) for allocating received addresses to segments (S1-S40) of a street system, and with a device (30) for reproducing the received coded signals in clearly understandable form, is equipped with an additional device (42) with a second memory (44) for travel parameters of the segments (S1-S40) stored in the first memory (16), and addresses for segments adjacent to the respective segment (S1-S40), with an input device (34) for at least one destination input which is to be allocated to a stored segment (S1-S40), with a computer (46) to determine the optimum route to the destination (ZP), and with a third memory (48) in which the segments belonging to the optimum route determined by the computer (46) can be stored. In conjunction with the segments (S1-S40) stored in the first memory (16), the additional device allows the reproduction of an optimum route, determined by the computer ( 46), to the destination that was entered.

Abstract: Traffic Condition information is settled by actuating a key (15, 16, 17, 18) of a four-way toggle switch (8) of a radio receiver in order to specify a directional quadrant. The position (34) of the radio receiver is established by the computer (5), using program comparison and identification methods, and traffic conditions information relating to the selected directional quadrants (30, 31, 32, 33) is issued via an output device (11), for example visually by a display or acoustically via loudspeakers (10) with the aid of a voice synthesizer (7).

Abstract: A navigation system is proposed, which is connected with a receiver for receiving and evaluating traffic advisories. The traffic advisories are transferred from the receiver to the navigation system, and the navigation system takes the traffic load indicated by the traffic advisories into consideration when determining a route from the present position to the destination. This makes traffic-dependent navigation possible. The reason for not choosing the usual route is communicated to the driver of the vehicle by a read-out of the respective traffic advisories and by their display.

Abstract: A radio receiver, in particular for vehicles, is proposed that is equipped with a decoder for decoding digitally encoded traffic news received, in particular in accordance with the RDS system. A station memory is also provided, in which all the receiver radio stations are stored in memory at regular intervals. This table is compared with a table stored in a memory of the receiver, in which the radio stations are assigned to certain regions. If a predominant match between the received radio stations and the stored radio stations is ascertained, then the associated region is output, and only traffic news associated with the applicable region is output.

Abstract: A method for IF bandwidth switchover and an IF bandwidth switchover apparatus in an AM radio receiver are described. This kind of switchover is appropriate if radio transmitters not only transmit at the normal modulation bandwidth but also broadcast programs with an expanded bandwidth. To obtain optimal reception, the switchover is performed as a function of the reception conditions. To this end, the error rate of supplemental AM information, adjacent-channel interference and the signal strength can be evaluated. These criteria can be used either individually or in various combinations.

Abstract: To permit transmission of traffic information by amplitude modulation in the medium wave band without disturbing audio signals being broadcast, a stereo pilot tone of frequency f.sub.pt below audible range is generated, as well as first and second sinusoidal signals of f.sub.1 =m.sub.1 /n.multidot.f.sub.pt and f.sub.2 =m.sub.2 /n.multidot.f.sub.pt, in which m.sub.1, m.sub.2, and n are different integers. The carrier is modulated by the stereo pilot tone and the first and second sinusoidal signals in such a manner that the phases thereof are different and further, when added, they do not essentially exceed the amplitude of the stereo pilot tone.
