Key Responsibilities

n

EE Architecture Definition

n

n
- Define the EE architecture master plan:
n
- Selection of communication networks:
n
- Automotive Ethernet
n
- CAN FD
n
- LIN
n
- Centralisation of power:
n
- Transition from a conventional architecture to a zonal architecture
n
- Centralized architecture around supercomputers
n

n

Power Architecture Management

n

n
- Manage power distribution, which is crucial in electric vehicles:
n
- High-voltage architecture (400V / 800V) for traction
n
- Low-voltage architecture (12V / 48V) for accessories and control units
n

n

Architecture Specification & Functional Allocation

n

n
- Draft the Architecture Specifications (AS), which will serve as the technical bible for the development teams.
n
- Break down and assign the vehicle's functions to the appropriate components or control units
n
- Define the software and physical (inter-system)



interfaces to ensure effective communication between the various control units.
n

n

Cybersecurity & Functional Safety

n

n
- Address cybersecurity from the early design stage.
n
- Ensure compliance with functional safety standards:
n
- ISO 26262
n
- ASIL
n
- ISO21434
n

n

Technology & Architecture Decisions

n

n
- Make technology choices at an early stage.
n
- Assess the cost-benefit ratio between a software update and the addition of a physical component (hardware).
n
- Perform architecture decision and trade-off analysis.
n

n

Physical Architecture & Optimization

n

n
- Work on the layout of electronic control units.
n
- Optimize cable harnesses for weight reduction.
n
- Support ECU layout and vehicle packaging optimization.
n

n

OTA & Scalability

n

n
- Ensure scalability:
n
- Design a scalable EE architecture
n
- Support OTA (Over-The-Air) remote updates
n
- Enable lifecycle software updates throughout the vehicle lifecycle
n

n

Upstream Activities: Upstream activities happen early in the development cycle, before detailed development and testing begin.

n

n
- Purpose is to define what needs to be built and how it should be designed.
n
- Typical Upstream Activities:
n
- Requirements Definition
n
- Architecture Design
n
- Risk Analysis
n
- Concept Development
n
- Planning & Governance
