Application

Purpose: Application and data is downloaded to the ECU‘s persistent memory.

(at Development, Manufacturing, After-Sales)

u General application which implements the general algorithms and diagnostic functions.

u Is usually implemented based on AUTOSAR.

u Bootloader (and flash driver) is used for reprogramming. Could also be implemented based on AUTOSAR components.

An ECU runs EITHER in the application OR (exclusively) the bootloader.

u Flash Tool

u Controls the flash sequence

u Transfers data to the ECU

u Bootloader

u Manages the entire software update sequence

u Erases the memory areas, transfers the new memory image to persistent memory

u Verifies data integrity

Reprogramming mainly at supplier before ECU isdelivered.

Seldom reprogrammingdue to short manufacturingtime. But ECU configurationis done here.

Reprogramming here if ECU is replaced.

Use Case Overview

Automated Flashing

u Flash execution controlled via

u Graphical user interface

u Automation interface (C and C# API)

16

Parallel ECU Reprogramming

Use Case Overview

Use case: Parallel flashing

u Parallel flashing of several ECUs each over separate bus

u In vehicle manufacturing or supplier assembly

u Efficient reprogramming of identical and different ECUs

u Applying late changes

u Applying OEM specific adaptations to generic pre-programmed ECUs

Solution

u Tool edition: vFlash Station

u Concurrent flashing of up to 8 ECUs, each over a separate bus

u Concurrent flashing over different bus types (CAN, CAN FD, FlexRay, LIN, Ethernet (DoIP))

u Each flash process is controlled independently

17

Standalone Flashing with VN8810

Use Case Overview

u Supplier’s production:Wirelessly control several flash processes on several VN8810

u Manufacturer’s production:Late software update shortly before assembling module in vehicle

u After vehicle production:Reprogramming ECUs assembled in vehicle (e.g. while shipping vehicles)

Standalone Flash Device: vFlash on VN8810

u Fail-safe execution

u Controlled via keypad

u Optionally controlled wirelessly via “Smart Device”

u No PC required for flashing

u No expert required for flashing

u Documentation of flash activities in Reports
