Abstract

A system for identifying a plurality of components of a vehicle that includes a plurality of non-volatile memories for storing identifiers associated with the plurality of vehicle components, a controller of the plurality of the vehicle components, a communication network configured for connecting the controller to the plurality of memories, and an identifiers memory including a portion to store a list of a plurality of type-approved identifiers associated with the plurality of type-approved vehicle components. The controller receives the identifiers, reads from the portion of the identifiers memory the list of type-approved identifiers, and checks if the identifiers of the plurality of components are included in the list of the type-approved identifiers, and when the controller detects that an identifier associated with a component out of the plurality of components is not included in the list, the controller blocks operation of the component.

a controller configured to be coupled to the vehicle components and spare components, the controller configured to;

receive from the plurality of memories vehicle component and spare component identifiers associated with the respective vehicle components and spare components;

read from the first identifiers memory the first list of the type-approved vehicle component and spare component identifiers;

detect if a received vehicle component or spare component identifier received from the plurality of memories is not included in the first list of type-approved vehicle component and spare component identifiers; and

block operation of the vehicle in response to detecting that a respective received vehicle component or spare component identifier is not included in the first list of type-approved vehicle component and spare component identifiers; and

a hardwired communication network that directly connects the plurality of memories to the controller.

6. The vehicle according to claim 5, wherein each vehicle component and spare component identifier and each of the plurality of type-approved vehicle component and spare component identifiers is a digital identifier that includes at least one from among the following bit fields:
