The components of the global architecture are merged using the following<br />

components of the subproblem architecture.<br />

7.5 Validation<br />

ACC Application<br />

CAN Bus HAL<br />

Actuator HAL<br />

ABS HAL<br />

ACC Application State<br />

ACC Application Increase Decrease<br />

ACC Application Overridden<br />

• The subproblem architectures have the same external interfaces as the<br />

problem diagram.<br />

• The phenomena of sequence diagram at the external interfaces are the same<br />

as the signals in the interfaces of the application layer.<br />

• The direction of all signals is consistent to each other and consistence to the<br />

input.<br />

• The architecture has the same external interfaces as the ACC controller<br />

component of the machine architecture developed in phase 5.<br />

The overall architecture contains all components of all subproblem architectures.<br />
