The SW Defined Vehicle
The Software-Defined Vehicle represents a paradigm shift in automotive, where software becomes the primary enabler of vehicle functionality, customization, and innovation. The components listed above work together to create a highly flexible, upgradable, and intelligent vehicle platform. This architecture allows automakers to improve vehicle performance, introduce new features via OTA updates.
Hardware Abstraction Layer (HAL)
Provides a bridge between the vehicle's physical hardware and the software layers.
- ECUs (Electronic Control Units) : Traditional vehicles have many ECUs, but in SDVs, these are often consolidated into fewer, more powerful domain controllers or centralized computing units.
- Sensors : Cameras, LiDAR, radar, ultrasonic sensors, etc., which provide data for perception and decision-making.
- Actuators : Devices that physically control vehicle functions like braking, steering, and acceleration.
- Gateways : Facilitate communication between different domains and networks within the vehicle.
Software for Compute Platforms
Acts as the "brain" of the vehicle, consolidating processing power for various functions.
- High-Performance Computing (HPC): These are powerful processors (e.g., GPUs, CPUs, and specialized AI accelerators) that handle complex tasks like machine learning, sensor fusion, and real-time decision-making.
- Domain Controllers: Instead of having separate ECUs for each function, domain controllers manage specific domains like powertrain, chassis, ADAS, and infotainment.
- Zonal Architecture: A newer approach where the vehicle is divided into zones, each managed by a zonal controller that handles local functions and communicates with the central compute platform.
Middleware Software
Middleware acts as the intermediary layer between the hardware and the application software, enabling seamless communication and integration.
- AUTOSAR (Automotive Open System Architecture) : A standardized automotive software architecture that facilitates communication between different software modules and hardware components.
- Service-Oriented Architecture (SOA) : Enables modular software development where different services (e.g., navigation, ADAS) can communicate with each other through APIs.
- Real-Time Operating Systems (RTOS) : Ensures that critical tasks are executed within strict time constraints, essential for safety-critical systems like braking and steering.
- Basic Software (BSW): including memory stack, communication stack and diagnostics stack. strong expertise with OSEK OS. Adaptive AUTOSAR configuration for POSIX Interfaces between OS and Applications.
Vehicle Software Technologies
These are the user-facing and functional applications that define the behavior of the vehicle.
- Infotainment Systems : Manage media, navigation, and connectivity features.
- Advanced Driver-Assistance Systems (ADAS) : Includes features like adaptive cruise control, lane-keeping assistance, and automated parking.
- Autonomous Driving Software : Handles perception, planning, and control for self-driving capabilities.
- Over-the-Air (OTA) Updates : Allows for remote software updates, enabling new features and bug fixes without requiring a visit to a service center.
- Vehicle-to-Everything (V2X) Communication : Enables communication between the vehicle and external entities like other vehicles, infrastructure, and pedestrians.
Connectivity and Networking
Ensures seamless communication between different components within the vehicle and with external systems.
- In-Vehicle Networks : Protocols like CAN (Controller Area Network), LIN (Local Interconnect Network), FlexRay, and Ethernet are used for communication between ECUs and sensors.
- Wireless Connectivity : Includes cellular (4G/5G), Wi-Fi, Bluetooth, and satellite communication for external connectivity.
- Cloud Integration : Cloud platforms enable data storage, analytics, and remote monitoring, facilitating features like predictive maintenance and fleet management.
Data Management and Analytics
Collects, processes, and analyzes data generated by the vehicle to improve performance, safety, and user experience.
- Edge Computing : Processes data locally within the vehicle to reduce latency for time-sensitive tasks.
- Big Data Platforms : Store and analyze large volumes of data collected from sensors, user interactions, and external sources.
- Machine Learning and AI : Used for predictive maintenance, personalized user experiences, and improving autonomous driving algorithms.
Functional Safety
We are certified ISO26262
Ensures that the vehicle operates safely even in the event of a failure.
- ISO 26262 Compliance : A standard for functional safety in automotive systems, ensuring that software and hardware meet safety requirements.
- Redundant Systems : Backup systems for critical functions like braking and steering to ensure fail-safe operation.
- Fail-Operational Architectures : Ensures that the vehicle can continue to operate safely even if some components fail.
Cybersecurity
We are certified ISO21434
Protects the vehicle’s systems and data from unauthorized access and cyberattacks.
- Secure Boot : Ensures that only authenticated software can run on the vehicle’s hardware.
- Encryption : Protects data both in transit (e.g., over-the-air updates) and at rest (e.g., stored in the vehicle’s memory).
- Intrusion Detection and Prevention Systems (IDPS) : Monitors network traffic for suspicious activity and takes action to prevent attacks.
- Firewalls : Protects the vehicle’s internal networks from external threats.
