Efficiency Through Reuse

Diagnostic Data in Vector Tools

CANdelaStudio is the root of the Vector CANdela Process; a process based on exact specification and reuse of resulting diagnostic data

Diagnostic data is efficiently described with immediate input validation, based on a template that ensures OEM requirements are met

Consuming tools: vTESTstudio; CANoe.DiVa; Vector Logger Configurator; CANoe/CANalyzer; CANape; Indigo; VDS-IDE; DaVinci Configurator; GENy

ECU Software Development

CANdelaStudio is able to generate:

ODX (and PDX) for use in tester parameterization

AUTOSAR DEXT for use in embedded software configuration

ODXStudio may be used to work natively with ODX files for single or multiple ECUs and is able to combine single-ECU files into a single ‘vehicle project’ file

CANoe CANape Indigo

VDS is a modern, .NET-based, diagnostic sequence language for diagnostic data in CANoe, CANape, vFlash and Indigo, and for worldwide deployment via Indigo Option Remote and vConnect

The VDS-IDE (Microsoft Visual Studio add-on) facilitates professional development of sequences:

A test framework is included for QA, and permits ‘Agile’ development techniques such as TDD to be employed

Rapid prototyping of sequences is possible with a ‘script recorder’ in Indigo and the VDS-IDE

CANoe.DiVaCANoe CANape Indigo

vFlash is a data-driven ECU reflashing tool for CAN, LIN, FlexRay and Ethernet (DoIP and SoAd)

vFlash may be run from a UI or integrated via an API into other tools (e.g. ECU manufacturer end-of-line)

vFlash provides other Vector tools with reflashing capabilities: CANoe; CANoe.DiVa; CANape; Indigo

Worldwide deployment is possible ‘at a click of a button’ with vFlash Option Remote and vConnect

Security

Only authorized and verified data shall be flashed by authorized persons.

Only authorized entities shall be able to collect data from a vehicle.

Only authenticated and authorized users should be a able to diagnose a vehicle.

Robustness

Reprogramming of a vehicle shall never fail due to remote communication issues.

Reprogramming has to be fail safe, rollback strategies are needed in case of problems.

Updates have to be reliable, the system must detect whether vehicles missed an update.

Efficiency

The footprint of OTA components in the vehicle should be small (network and ECUs).

Data Collection should use resources of vehicle, backend and connection economically.

Live Diagnostics should not impose high requirements on the connection.

Responsiveness

Live Diagnostics via OTA should be almost as responsive as a local tester.

Requirements for automotive OTA – Security is essential
