Definitions

  • the invention relates to a car radio, with a base part permanently installed in a car, which is connected to the car battery, antenna and loudspeaker, etc., and with a removable control unit, which contains the essential control elements for the car radio.
  • Car radios of this type are enjoying increasing popularity because the removable control unit is flat and light and can therefore be easily carried in a clothes bag or handbag. In this way, good theft protection is provided, since the base part remaining in the car without control unit, also called control panel, is worthless for potential thieves, whereby the function of the base part can usually only be activated via a code contained in a code memory of the control part.
  • car holders For mobile phones, colloquially called “cell phones”, car holders are available which on the one hand give the phone a secure mechanical hold and on the other hand contain an interface for the power supply of the phone, for an external antenna and to an external speaker / microphone, so that hands-free talking is possible is. If necessary, there is a control line for muting the car radios during telephone calls.
  • control unit is designed as an operating and telephone unit which has a keypad for operating the telephone and at least partly the car radio, a display for telephone and car radio functions and an interface at least for the telephone antenna, audio lines, control lines and the power supply
  • the control and telephone unit can be used as a stand-alone mobile phone in the removed state and can be used in conjunction with the base part both as a mobile phone with a hands-free function and as a car radio control.
  • the invention therefore assumes that one and the same device is available for operating the car radio and for use as a mobile phone. In this way there are a number of advantages as follows.
  • the anti-theft protection for the car radio is provided by removing the control and telephone unit. Furthermore, there is no separate holder for the mobile phone, i.e. the control and telephone unit is required, whereby handsfree talking is also possible without additional installation.
  • the existing holder and the possibility of hands-free calling encourage the user not to take the mobile phone in his hand while driving and in this way to make phone calls, so that driving safety is increased and the transmission power is not close to the head but via the external antenna is emitted. Since a mobile phone is usually taken with you when you get out of the car, the theft protection for the car radio is given. It is advantageous if the operating and telephone unit has at least one code memory, to which an external evaluation unit of the base part is assigned via the interface. In this way, it is possible to use a code card (“SIM card”), which is required for mobile phones, for example, to protect the car radio (or the base unit) from theft.
  • SIM card code card
  • the base part has a code memory to which the internal evaluation unit of the operating and telephone unit is assigned via the interface, since in this case it is also possible to telephone with an optional additional code card of the base part, if in the Control and telephone unit no code card is available.
  • the display on the display is electrically rotated by 90 ° if the operating and telephone unit is connected to the base part, since the display can thus be read without any particular difficulty even while driving.
  • the reading is made easier if an additional display is assigned to the operating and telephone unit via the interface.
  • the additional display can on the one hand be made larger and on the other hand can be arranged more favorably for the driver in the field of view.
  • control unit and telephone unit including the battery charging, is supplied with power from the base part via the interface, since in this way the battery serving the mobile phone is not only not discharged during use in the car, but is also recharged if necessary.
  • the microphone contained in the operating and telephone unit can be used in hands-free mode, it is often more expedient if the operating and telephone unit is used the interface is assigned to a hands-free microphone, since such a hands-free microphone can be brought close to the head of the driver (or front passenger).
  • Fig.l in a diagrammatic representation of a base part with control and telephone unit and
  • FIG. 2 shows in a block diagram the essential elements of a car radio of the invention.
  • a car radio consists of a base part BAS, which is connected to the car battery BAT, the antenna ANT 2 and speakers LAS 2 etc., and a removable control and telephone unit BTE.
  • This control and telephone unit BTE can either be electrically and mechanically connected to the base part BAS, as is the case with removable control panels of known car radios, or it can serve as a self-sufficient mobile phone, which will be described in more detail below.
  • the optically visible elements of this control and telephone unit BTE are a keypad TAF, a microphone MIC 1, a loudspeaker LAS 1, a display DIS 1 and possibly an antenna ANT 1.
  • the operating and telephone unit also has a radio and baseband part FBB for the telephone function, a built-in battery ACC for the power supply and a code memory SIM 1, as is customary, for example, in devices based on GSM -Default work.
  • FBB radio and baseband part
  • ACC built-in battery ACC
  • SIM 1 code memory
  • ⁇ memory RCO in the operating and telephone unit BTE a radio code.
  • An external antenna ANT 2 of the vehicle is connected to the control and telephone unit via the interface SCH via an antenna line ANL, via radio lines AUL, control lines STL and supply lines VEL the radio part RTE, which in turn has a receiving part EMT, an audio amplifier AUT and an on-board power supply unit NEG and, in addition, in this embodiment, a cassette drive CLW and a CD player CDP.
  • the base part BAS can contain an external evaluation unit AWE for the code memory SIM 1 of the operating and telephone unit BTE, for which a data line DAL is connected via the interface SCH. It is also possible to arrange an additional code memory SIM 2 in the base part BAS, to which an internal evaluation unit AWI of the operating and telephone unit BTE is assigned via the data line DAL.
  • the base part BAS is connected to the vehicle battery BAT and, on the other hand, loudspeakers LAS 2 are connected to the base part BAS in a known manner.
  • a hands-free microphone MIC 2 and an additional handset ZHH can also be provided, for example for the front passenger.
  • an additional display DIS 2 can be provided.
  • control and telephone unit is used separately from the base part BAS, it represents both a form and a function of a conventional mobile phone, for example according to the GSM standard.
  • the control and telephone unit BTE is used to operate the radio receiver part or cassette drive, CD player etc. whereby the usual entries and Commands are sent to the car radio, such as station search, forward and reverse, etc.
  • the control and telephone unit is usually connected horizontally to the base part BAS with its longitudinal dimension, it is recommended that the DIS 1 display be electrically connected by 90 ° in this connected state to rotate so that the driver has no great difficulty in recognizing letters, numbers and symbols.
  • the additional display DIS 2 which can be arranged, for example, in the driver's field of vision.
  • the radio part When incoming or outgoing telephone calls are made, as is already known, the radio part is muted, if this was in use, and the calls are made in hands-free mode, with one or more of the loudspeakers LAS 2 installed in the vehicle serving as loudspeakers and as the microphone either Microphone MIC 1 of the control and telephone unit BTE or the hands-free microphone MIC 2.
  • a passenger can make calls using the additional handset ZHH.
  • an additional keypad TAF 2 e.g. to be arranged near the steering wheel or on the steering wheel so that the driver does not have to remove his hands too far from the steering wheel when entering a telephone number.
  • the activation of the radio can be made dependent on the fact that the external evaluation unit AWE reads the code memory SIM 1 via the data line DAL and only initiates the activation if the code is correct.
  • the power supply of the operating and telephone unit is carried out at BTE connection with the base part BAS via the electrical system ⁇ NEG device of the base part BAS, wherein also a recharging of the battery ACC can constantly follow the operating and telephone unit BTE ER.
  • the antenna ANT 1 When the control and telephone unit connected to the base part BAS, the antenna ANT 1 is out of operation and the radio communication is carried out via the external antenna of the vehicle ANT 2, which in addition to improved reception conditions also ensures that high-frequency power is not emitted close to the operator's head.
  • the dimensions of the control and telephone unit BTE correspond to those of the "cell phones" that are usually used, and from the external appearance only the keypad TAF differs from that of a conventional cell phone, since this keypad is also required for operating the radio.
  • the keypad it should be expressly made clear that it can also be divided where appropriate, which means that a part of the keypad can also be provided on the base part, e.g. that for the operation of a cassette or CD part. It should also be mentioned that the dimensions of the base part are usually standardized, as a result of which the maximum dimensions of the operating and telephone unit BTE are fixed.
