What should be accomodated in what? (desired
output and main contentual components)
Approval of systems (which systems?) / whole
vehicles Scope (passenger car heavy
vehicle combination)


EVSC specific definitions
Full functionality
Design requirements of systems
Performance requirements of systems

Interconnection of systems
Failure modes
Performance requirements of vehicles
Test methods of systems (HIL etc)
ISO methods
(x-y-z coordinates)

Concepts
Approaches from minimal to maximal
no special EVSC approval
special EVSC approval possible
extension of brake and steering approvals as far
as these systems are concerned (like in slide 4)
EVSC definitions, vehicle performance, CEL,
references... any other system appr.

A New Horizontal Regulation?
Like Reg.10/02 (EMC), Complex Electronic Vehicle
Control System concept
For vehicle type approval may be omitted in the
first phase.
Brake, steering extended functionality
Composition of single approvals
(Supplementary EVSC vehicle approval)
(CEVSC approval)
For EVSC system approval desirable.
The composition of single approvals, granted to
the vehicle, is not appropriate test reports
based on provisions of single regulations may be
utilized, if they are modified accordingly.
