- the signal for detecting the movement can also be a signal that is already used for the GALA function of an audio device is used, which allows it to automatically adjust the playback volume when playing audio signals depending on the Stop noise in the vehicle.
- the noise signal can in particular be known GALA signal in the prior art, which automatically allows the Playback volume at reception depending on the driving speed adjust. This automatic control of the volume is under the term "noise-dependent volume increase" (GALA) known. Since the noise in the Passenger compartment occurs only when the vehicle is moving, the driving speed is on suitable means for detecting the movement of the vehicle.
- the device comprises a Ignition sensor.
- This can be a signal generator directly on the ignition lock or a sensor on one other components of the ignition system such. B. ignition coil or the like, the so generates an engine start signal.
- the device comprises a data discriminator for messages on the cross-system data bus of the Vehicle.
- This data discriminator can be a simple monitoring device for be certain data sequences on the data bus, e.g. B. a command that is common immediately after starting the vehicle on components of the vehicle from a is sent to the central controller, which occurs when a predetermined data sequence occurs outputs a corresponding signal.
- other signals on the data bus can be "intercepted", which indicate the movement of the vehicle or the engine running. In particular, these can be signals for Switch the ignition on and off, to activate / deactivate the alarm system or for remote control of a central locking system and the like.
- the invention relates to a radio with the features of the claim 11th
- the radio device has the advantage that it is independent of driver operation When vehicle movement is detected, all available digital data and in particular the data about the current traffic situation are collected immediately and the driver at Need is informed. This means that the driver does not have to work on his own what can be "forgotten”. In addition, all digital data is also available for other vehicle components immediately available for example a navigation device.
- FIG. 1 The embodiment of a device according to the invention shown in FIG. 1 has one central unit 4a, which is connected to other peripheral components.
- One of the peripheral components is a receiving element 1a for receiving remotely transmitted ones digital data represented by an antenna symbol.

- receive element 1a also be designed to receive GPS data with a different frequency be broadcast.
- the playback device comprises one or more im Vehicle speakers.
- the central processing device 4a comprises in the embodiment shown in FIG. 1 a receiver device 1, which in the simplest case is a (FM) tuner.
- the Receiver device 1 is connected to the receiving element (s) 1a.
- the receiving device 1 can have a plurality of receiving devices Include (tuner) of the same design, so that switching from a current one Reception frequency to a different frequency is possible. This is particularly from Advantage as long as no RDS with transmission of alternative reception frequencies is available to which the system can automatically switch.
- the switching of the frequency is controlled in a control unit 4 in the central unit 4a.
- the data of the individual receiver devices from the Control unit 4 analyzed in terms of their reception quality, and depending on a second receiver device (not shown) is connected to the result and a search is started to find an alternative frequency.
- the incoming data In addition to the reception quality, its content is also analyzed. That is, if digital When data is received, its playback is highlighted accordingly. In particular, it is played at an increased volume. This analysis is done in one Processing device 2, which is shown with an amplifier symbol in FIG. 1.
- the Processing device 2 is connected to the reproducing device 2a.
- the activation of the receiver device 1, the selection of the cheapest reception frequencies with several receiver devices 1 and the forwarding of the received Data for evaluation and playback to the evaluation device 2 and the playback device 2a is carried out by the control unit 4.
- the control unit 4 gives the switch-on signal to the above-mentioned components only when necessary to reduce power consumption to keep small in the vehicle of many and powerful components.
- the device according to the invention comprises, as an external component, a sensor 10 which outputs a signal to the control unit 4 when the vehicle drive is started, which in turn the activation signal to the receiver device 1 and other components outputs. This means that only the equipment that is actually required is always in active state held.
- the monitoring of the data bus is on as a motion sensor corresponding signals indicated.
- the vehicle has an electrical system 6 with a digital one Data bus via which the control unit 4 with further components, not shown of the vehicle communicates.
- a Data discriminator 11 is provided, which during the "normal" operation of the vehicle none Has a function, but which signals the data bus when the vehicle is started Vehicle is listening to the z. B. initiate certain vehicle components. In particular these can be signals for switching the ignition on and off, for activating / deactivating the alarm system or for remote control of a central locking system and the like. In order to simple and reliable monitoring of the movement of the vehicle is possible.
- the In the simplest case, data discriminator 11 can be an AND gate in the case of a parallel bus as CAN after a branch to tap the vehicle electrical system, this is only a signal with the logical value 1 if a certain bit sequence is present on the bus.
- the pulse trains would first be in after tapping a correspondingly wide shift register 3 is fed, which continuously with the system clock rate is updated, and then the same analysis of the data followed as in parallel bus
- the data discriminator 11 is shown in FIG. 2 as an external component. However, he can of course also be integrated in the central processing unit 4a.
- the central processing unit 4a additionally an internal data bus for the transmission of messages between the control unit 4 and other internal components 5a, 5b and 5c. These components are intended for the caching of important information.
- Voice data memory 5a in which traffic information is stored, so that the driver can listen to it as often as you like.
- a memory for digital Traffic data can be provided in coded form 5b, in which the messages are only in short form are stored and their "verbalization" only in the evaluation and playback device 2 or 2a takes place, which has the advantage that the playback is always in the desired language.
