二、未来汽车基础设施需求

主要驱动因素

Automated Driving
Car-2-X applications
Vehicle in the cloud
Vehicle in the cloud

需求

High computing power
High data rates
High availability, fail-operational systems
Update over the air
Safety and security needs

三、整车架构

传统架构

以太网CAN/CAN-FD以及网关连接到一个中央网关上
以小的控制器为主

未来Vehicle EE 架构

以大的控制器为主

整车软件架构

OS（QNX 、Linux、Android、PikeOS），domain控制器级别的OS(基于MCU、MPU就称之为domain)
OTA、Diagnostic、BigData
Safety、Security
domain级别的OS

Domain 硬件架构

多处理器（CPU、GPU）
Cameras、RFadra、Lidar
以太网、CAN、LIN、FlexRay

Domain软件架构

目前大多厂商以一个高通芯片上虚拟出一个QNX一个Android
AutoSar是一个在OS上的应用（中间件），它并不是OS
自动驾驶推动了AP的产生

四、CP vs AP

五、AP架构

基于AutoSar17.03

Developed in C++ (C14/17)

OS will provide POSIX PSE51 interfaces to the application but Adaptive Platform will require further features

Platform Health Management

Alive Supervision

Execution Management

Lifecycle management of platform (machine) and application (process) incl.
privileges of access control and machine states
Communication Management
SOME/IP based including serialization and service discovery.
publish/subscribe mechanism for intra- and inter-ECU communication.

Diagnostics

Event memory management and diagnostic service handling.

Update and Configure Management

UCM is responsible for updating, installing, deleting and saving software records on the adaptive platform

State Management

Mainly responsible for the state switching of the entire machine state and its functional groups, and notify the EM to perform related state switching.

RESTful

It is a design style and development method of web application, based on HTTP, can use XML format definition or JSON format definition.

ldentity and Access Management

Introduces separation of privileges for adaptive applications and prevents privilege escalation during attacks

Log And Truce

Use AUTOSAR standard protocol DLT, function similar to Glog(google).

Time Synchronization

For time synchronization between different systems, the accuracy can reach sub-microsecond level

Cryptography

Provides APIS for common encryption operations and security key management.

Signal to Service

can总线是以信号为基础的
COnversion from data signal to service

1.Execution Management与State Management的关系

2.Service-oriented communication

SW components executed on the adaptive platform will use service-oriented communication.
Communication paths can be established at design- and at run-time.

Feature

ara::com
SOME/IP、IPC、DDS
Method、Event、Field
Proxy、Skeleton
Tag Length Value/TLV（【基础】TLV 报文格式详细解析）
Transport layer Security/TLS
（1）TLS报文：LS是在SSL的基础上标准化的产物，目前SSL3.0与TLS1.0保持一致，二者是并列关系。SSL/TLS位于传输层和应用层之间，应用层数据不再直接传递给传输层，而是传递给TLS层，TLS层对从应用层收到的数据进行加密，并增加自己的TLS头。
（2）实验六 TLS协议报文解析
Design and Implementation
Code Generation
Service Discovery finds all local and remote Service Instances in the System.
Available Service Instances are represented by Proxies (P1…P3) to the Application.
Application can choose which Service Instance(s) to use.

2.Diagnostic Management

Feature：

ISO 14229-5(UDSon IP)
including fault-memory(DTL)handing
including transport layers(ie.DoIP - ISO 13400-x)
ARA service: Uses ara::com interface

3.Persistency

In AUTOSAR Adaptive the Persistency cluster provides a library based implementation to access non-volatile memory to Adaptive Applications so that data can be stored non volatilely.

Key-Value Storage

Multiple values stored in one storage location
Addressing of single values by using a key as idefier
Multiple storage locations/databases can be used
Database format not specified by AUTOSAR

Stream Storage

Raw access to storage locations/files
Used for access to files in any format
API derived from C++ Standard Library std::fstream classes

4.Log and Trace

The AUTOSAR Adaptive Platform Logging provides interfaces for Applications to initialize a Logging
framework, forwarding logging information and to convert decimal values into the hexadecimal or binary system.

There are three main storage media for this function ：Terminal, File. and Remote Client.

Main Tasks

Provide interfaces for Adaptive applications to forward logging data.
Provide interfaces for data conversion (Hex, Dec, Bin).

5.安全支持

6.安全方法

7.信息安全

AUTOSAR goals

Support the development of secure systems through the two standards
To provide layered automotive security approach, to define measures at specific layers:
Individual ECU
In vehicle network
E/E architecture
Connected vehicle

Provide and support Coexistence and Interoperability of Security measures between CP and AP

Adaptive Platform Security Feature Team

Responsible for providing features that enable the development of a secure system
Provide security controls to platform functional clusters and for secure deployment of adaptive platform application

8. AutoSar：Transparent To Other standards

The adaptive AUTOSAR specification is not original, but draws on the strengths of various companies, such ad SOME/IP、DDS、RESTful、TimeSync、etc

Feature：

Safety && Security
Connect
OTA

9.AP development Workflow & Methodology

platform development
application development
integration
deployment
execution

10.AP EB Developemt Enviroment

AP Vector Development Environment

11. Adaptive Applications

Application

Multi-threaded
Execution states
Manifest contains platform related
information (recovery action,dependencies to services or libraries)
Instance config contains application specific static information (variant, options, …

Interfaces

ara::com for communication with adaptive services
(basic services and user applications)
PSE51 is the usable OS API subset
The Adaptive AUTOSAR Foundation clusters (Execution Managemer+ Persistency, etc.) are available
