VEHICLE MOTION CONTROL DEVICE (BLACK BOX) Russian patent published in 2023 - IPC G07C5/08 

FIELD: instrumentation.

SUBSTANCE: invention relates to the field of instrumentation and can be used for operational registration and control of the technical condition and operation of vehicles, as well as the psycho-physiological state of drivers in the investigation of traffic accidents. The device for monitoring the parameters of the movement of the vehicle contains equipment located on the vehicle, and equipment located at the point of reception and control. The equipment placed on the vehicle includes a magnetic recording apparatus 1, the first 2, second 3 and third 4 drives of the magnetic recording carrier transportation mechanism 5, a universal magnetic head 6, an erasing magnetic head 7, an erasing generator 8, a control unit 9, a time relay 10 , vehicle wheel 11, first 12 and second 13 switches, playback unit 14, first 15 and second 22 distribution blocks, mark sensor 16, recording signal source 17, brake system status sensor 18, alarm devices 19, headlights 20, compression force by the driver steering wheel 21, master oscillator 23, phase manipulator 2, frequency manipulator 25, amplitude modulator 26, power amplifier 27 and transmitting antenna 28. , synchronous detector 32, first 33, second 42 and third 47 registration blocks, phase doubler 34, first 35, second 36 and third 37 PLL blocks, first 38, second 39 and third 40 phase dividers by two, frequency demodulator 41, first 42, second 44, third 46 and fourth 49 phase detectors, reference oscillator 48, driver 50 control signal, local oscillator 51 , mixer 52 and amplifier 53 intermediate frequency.

EFFECT: increasing the sensitivity and range of the reception and control point by building it according to the superheteradine scheme.
