PECULIARITIES OF CONDUCTING FORENSIC RESEARCH ON PASSENGER SRS VEHICLE SYSTEM TO ESTABLISH THE REASON NOT CAUSE THE FRONT BUCKLES

Issues that arise from experts during the performance of court automotive expert assessments (expert researches) of technical condition of automobiles are considered, namely: SRS passive safety systems. The sequence of carrying out elemental research of the passive safety system of the SRS of cars on establishing the reasons for failure of the front (front) airbag of the passenger during a traffic accident is presented. The urgency of this paper is due, on the one hand, to the mass installation of airbags on cars of different brands, which are intended to protect the driver and passengers of vehicles from injuries during a collision, and on the other hand, frequent cases of not triggering airbags in the collision, associated as both for technical and operational reasons, resulting in serious injuries to the driver and passengers in the event of a collision. The increase in the level of constructive safety of the car, above all, is ensured by strengthening the requirements for the development, installation of structural elements and systems that provide protection of life and health of road users. Given the diversity of sources of risk factors for road accidents, constructive safety is divided into active, passive and after emergency. The examination of the technical condition of the SRS passive safety system is essentially a study of the vehicle electrical system requiring safety measures, since damage to the insulation of wires, shorting of individual circuits of electrical wires, and the introduction of extraneous current to the connectors can lead to the deployment of airbags during research.

Research on the Calculation of Auto Power Balance

Based on the research and analysis of power balance calculation method for the whole vehicle electrical system, example of specific project, detailed analysis and statistics of the whole vehicle with electrical power demand in different work conditions. And analysis and design the key parameters on the battery capacity, the size of the generator and starter. Preliminary verify the proposed method feasibility through specific calculation in this paper.

Design of CAN-Bus Control Modules for Passenger Car

The construction scheme of CAN-bus modules on passenger cars is designed in this paper according to the development trend of safety and information intellectualization. The scheme includes functional partition of vehicle, electrical system classification, control unit division, and the assignment of the network ID. In particular, a detail description is given to the position and functions of input and output control modules. Tests have been given by OEMs to prove its practicability and validity.
