FIELD: transportation. ^ SUBSTANCE: system incorporates a mike unit with its output connected to the first input of the digital processing system. The said system second input and output are connected to the micro controller first output and input, respectively. The micro controller second input is connected to the control unit output and can generate control signals for actuators and alarm signaling units. There is also a storage unit with its input and output connected to the micro controller second output and thirds input, respectively. The control unit allows a dynamic identification audio dialog between the system and the vehicle user including the stages of training, preliminary identification and final identification. The storage unit is intended to store text instructions and messages, digital audio records of phrases-passwords and their digital codes. The incorporates also a random numbers generator and text instruction and message display. The micro controller comprises two additional inputs and two additional outputs. The random number generator input and output are connected to the micro controller first additional output and first additional input, respectively. The second additional input of the said micro controller is connected to the mike unit output, while the second additional output being connected to the text instruction and message display unit. ^ EFFECT: invention rules out any chances of the system deception by secret recording passwords pronounced by the user and subsequent reproduction between internal or external mike. ^ 2 cl, 4 dwg |
