1 PURPOSE
The purpose of this document is to specify SW diversity of the part “EPS K5” and the
associated test benches.
This document belongs to the contractual documentation of consultation.
2 SCOPE
The EPS Software is expected to be used for multiple vehicles on the K5 plate-form.
The diversity must be managed by the common software for all the vehicles.
