Electrical Model of Car Power Wiring for Transmission of Pulse Control Signals Through it

The reduction in the number of hijackings is associated with the quality of the car alarms installed by owners on cars. Such systems contain electronic relays that are remotely controlled by the main alarm module, breaking the vehicle's electrical circuits to prevent theft. The use of relays, working on Power Line Communication technology and receiving control signals via the power wires of the car is deemed perspective. Such relays are not wired to the main alarm module, they are difficult to detect and neutralize. Branching of the wiring, the presence of impulse noise in it, as well, as the low internal resistance of the battery, make it difficult to transmit and decode the pulse control signals. The creation of electronic relays requires the development of an electrical wiring model that adequately reflects control signal transmission processes. This paper presents a model of wiring, a special place in which is given to the calculation of the internal inductance of the battery, which is a part of the model. The results of modeling and experimental studies confirm the adequacy of the model.
