<p>PURPOSE:To prevent unnecessary actuation of a driving system which is operated by voice, headlight lamps, for instance, and insure safety during running, by providing an operation control means to intercept signals for each driving mechanism. CONSTITUTION:A car-speed sensor 8 generates an electric pulse corresponding to the car speed, and upon receiving this pulse a frequency-voltage transducer 10 produces output voltage of a level corresponding to the frequency of the pulse received. This output voltage is compared with the reference voltage at a comparator 11 to detect and determine whether the car is running or not. If it is less than the reference voltage, the car is judged parking, and ''High'' signal is sent to an ''AND'' gate 6 and ''Low'' signal to another ''AND'' gate 7. If it is larger, the car is judged running and signals contrary to the above are sent. Thus, only when two inputs to the ''AND'' gate 6 are ''High'' signals, it issues a signal to a trunk-open mechanism 3 to open the trunk. This trunk opening operation is performed only when an audio recognition unit 2 recognizes specific words and at the same time the car is parking.</p> |
