| 摘要 |
The invention relates to a radio remote control system for transmitting remote control signals to at least two remote controllable objects located in a motor vehicle and in the proximity of a motor vehicle, whereby a first object is remote controlled by amplitude-modulated radio signals (AM) and a second object is remote controlled by frequency-modulated radio signals (FM). The aim of the invention is to provided a system integration for economically expanding the function of a central locking remote control using a garage door opener remote control in the motor vehicle. To this end, channels (A and B) which transmit at least two amplitude-modulated signals and which are used for command input are provided between at least one control device (1) and the first object (2) which is controlled by amplitude-modulated remote signals. In addition, the first object (2) has means for differentiating the command signals of the second channel (B) received by the control device (1) from those of the first channel (A), and comprises transmission means (3) for transmitting signals to a transmitting device (5) which generates the frequency-modulated remote control signals. |
