Board device CONTROL PARAMETERS FOR VEHICLES IN ROAD TRAFFIC ACCIDENTS

摘要

The proposed invention relates to the field of intelligent vehicles and is designed to control vehicle movement parameters and construct a spatial path of movement of the transport means of recorded data for analysis of the causes of road accidents.; Essence of the technical solution lies in the fact that the on-board device controls vehicle motion parameters during a traffic accident, comprising means for measuring vehicle parameters primary converters connected to the input of the microcontroller, to the output of which is connected a block of non-volatile data memory, as well as the microassembly service electronics, means for measuring parameters of vehicle movement primary converters designed as the Free tformennogo inertial unit on the basis of micro or nanoelectromechanical transducers oriented with their measuring axes, respectively, in the direction of the longitudinal, vertical and transverse accelerations of the vehicle, and a nonvolatile data memory unit - a non-volatile flash memory. Furthermore, addition, it may be administered connector of the onboard electrical network, uninterruptible power supply, a backup battery, a secondary power source, GPS / GLONASS receiver, a connector for GPS / GLONASS antenna, GPS / GLONASS, GSM transceiver, GSM antenna connector, GSM antenna, USB-connector, micro-service electronics comprise an information source supply line, power bus, data bus strapdown inertial unit, information GPS / Glonass bus GSM bus information, information bus flash memory, data bus USB-memory, the microcontroller comprises a controller strapdown inertial unit controller GPS / GLONASS, a mobile communication controller receiver (GSM), a flash memory controller, USB controller connected thereto corresponding to said service electronics tires, as well as IO controller associated information source from the power line uninterruptible power supply, and a controller associated power line with the secondary power source strapdown inertial unit m based on micro or nanoelectromechanical transducers receiver GPS / GLONASS and GSM transceiver, wherein the connector of the onboard electrical network, connected to an uninterruptible power supply comprising a backup battery and is connected to the secondary power source.; The proposed utility model is achieved technical result, which is to increase the accuracy of determining the trajectory in the pre-fault period in time of the accident and expansion functionality by providing an automatic remote dispensing parameters post-accident situation evaluation from the state of the roadway during the movement. Simultaneously, the simplification of construction of the device is achieved and its dimensions are reduced.
