Building a Requirements Traceability as Part of the Safety Case

Customer Requirements

e.g. Steering angle assured by ASIL-D

e.g. Mechanical and software based

steering endstop

Hazard AnalysisIdentification and classification of

safety risks and hazards. e.g. Safety Goal : no uncontrolled

actuation of steering systemRisk: uncontrolled actuation can

happen with wrong sensor input or steering command

FMEA / FMEDAAnalysis of hazards and

safety risks and measures by FMEA and FMEDA

e.g. Measure: redundant and diverse rotor position

sensors, comparing internal steering angle with external (ADAS command)

steering angle.

System Requirements Specification

System Requirements

e.g. Steering angle is measured internally and

reported on the bus.

Safety Requirementse.g.

we need to trust the steering angle at ASIL D, 2 redundant diverse rotor positions, plausi check, safe state in

case of deviation.Safe state is assured by a 6 or 12 phase motor with a limp home

mode (in ADAS mode with no driver interference).

(ASPICE) SYS.2.BP3 Analyze the impact on the operating environment. Determine the interfaces between the system requirements and other components of the operating environment, and the impact that the requirements will have. [Outcome 3]

ISO 26262-4, 6.4.1 Specification of the technical safety requirementsISO 26262-4, 6.4.1.1 The technical safety requirements shall be specified in accordance with the functional

safety concept, the preliminary architectural assumptions of the item and the following system properties:

a) the external interfaces, such as communication and user interfaces, if applicable;b) the constraints, e.g. environmental conditions or functional constraints; andc) the system configuration requirements.NOTE: The ability to reconfigure a system for alternative applications is a strategy to reuse existing systems. NOTE: See questions for ISO 26262-4, 6.4.1 and ENG.2 BP1.

(Security) SAE J3061, 8.3.1 Feature DefinitionThe feature definition defines the system being developed to which the Cybersecurity process will be

applied. The feature definition identifies the physical boundaries, Cybersecurity perimeter, and trust boundaries of the feature, including the network perimeter of the feature. …

Mobile internettechnologies

Infrastructure base stations

Driving events databases(OEM, authorities)

Driving data analysis

Cloud driving services

Vehicles report driving events into the cloud:

E.g. position, speed, steering angle, obstacles

detected, ...

Vehicles get driving situation, recommendations, commands from the cloud:E.g. steering related:* instantaneous steering angle of neighbor cars* typical steering angle for road position, * obstacles detected, ...

Radio-navigation satellite systems

Cloud based infrastructure for driving support

The world is biggerADAS (connected) environments

Critical signal path scenario

1. Vehicle local sensors (correctness?)

2. signals sent to service infrastructure (correctly related to position etc.?)

3. Cloud storage (corruption?)

4. merge with other cars signals (data poisoning?) in the current vicinity (correct location?) and those ever operated near the current position (depending on the algorithm for driving data analysis, and its correctness).

5. Up-to date steering angle recommendation& road conditions for the current position sent to all the cars (availablitiy, low latency, correctness, scalability?).

6. Steering angle is applied to the cars’ steering (correct in the current context?).

EuroSPI 2017 6.-8.9.17 35

Proposed ASPICE extension for Automotive Service Infrastructure (ASI processes)

Expected typical properties • “ASIL-D” QoS (Quality of Service) service monitoring for correct operation,

availability, scalability and low latency. • Preparedness for interruption of connectivity - local take-over (challenging for

eg. platooning) • Cybersecurity of service infrastructure (eg. wrong data injected, services

spoofed, stored data and algorithms tampered with, messages altered) • Etc.

EuroSPI 2017 6.-8.9.17 36

Extension of ASPICE for Automotive Service Infrastructure ASI processes

By example: ASI.2 Requirements Analysis Base practice BP4

ASI.2.BP4: Analyze the interfaces between the vehicle and the service infrastructure. • Analog and linked to “SYS.2.BP4: Analyze the impact on the operating environment” • Identify the interfaces between the vehicle and the service infrastructure.• Analyze the impact that the service infrastructure interfaces will have on the vehicle

operating environment. • OUTCOMES: Quality of Service (Availability), Defined reaction in case of no availability,

criticality of information, safety classification (if provided as QM or validated among a set of data to be provided with an ASIL), encryption and identification mechanisms to be implemented.

Extended Cybersecurity (SAE J3061:2016) Assessment Questions :• Related to SAE J3061:2016, clauses 8.3.1 Feature Definition – identifies

• physical boundaries, • Cybersecurity perimeter, and • trust boundaries of the feature, including the network perimeter of the feature.• The feature definition defines the scope and interfaces of the feature.
