The flash programming of electronic control units (ECUs) in vehicles has now become widely accepted: There are anywhere between 3 and 120 ECUs depending on the market segment. These can usually be supplied with new software directly or via a gateway using a tester. This capability is used in a number of ways, although a vehicle interface currently has to be plugged in to mediate between the programming application and the ECUs. In the future, over-the-air updates will open up further possibilities.

After replacing or repairing vehicle components, the ECU and its peripherals must be adapted to each other again. In addition to only functional sequences, interaction with operating personnel to start individual process steps or enter parameters is often necessary. The advantages that OTX and the Softing OTX tools offer for a fast and robust realization of commissioning sequences are obvious.

The ISO standard on diagnostic communication “Diagnostics over Internet Protocol” – or DoIP for short, is becoming increasingly prevalent in modern vehicle architectures. This is not surprising as the advantages of this innovation are obvious. On the Internet, it is normal to transmit large amounts of data – in modern vehicles, data packages of several GBytes are no longer unusual. The trend towards remote diagnostics is also unstoppable, which is why the current edition of the ISO 13400 standard details the necessary data backup. The answer: DoIP with TLS.

Vehicle Communication Interfaces (VCIs) are the central component when it comes to tester systems accessing the electronic control units (ECUs) that perform a wide range of control and regulation tasks in modern vehicles, including diagnostic functionality. The answer to the increasingly complex tasks and requirements of diagnostics is the multipurpose VCI VIN|ING 2000.

A large number of different cables, adapters and peripheral simulations are used in the engineering of vehicle electronics, the testing of electronic and electrical components and in component integration into the complete vehicle. The use of standard products is rarely possible here. Test equipment specially adapted to the control unit, vehicle series or test environment is nearly always required.

A range of original components can be conveniently attached and connected to each other on test boards according to their target arrangement in the vehicle. This is the perfect way to subject, in particular, the cable harness and ECUs to complex networking and function tests in conjunction with real sensors, actuators and other subsystems. Test boards thus enable flexible tests for series validation – long before tests are possible on real vehicles.

Software is the most important driver of automotive innovations. And this is why software must be developed to an appropriate level of safety to ensure that, in the case of a fault or error, neither the driver of a particular vehicle or other road users should suffer any harm.

ECU and vehicle updating is an important application area for Softing DTS.monaco, as an accompanying measure in the engineering process to validate various software versions, but also to prepare the automated flash procedure for manufacturing and after-sales service.

Vehicle engineering is facing a range of challenges. This is why today manufacturers and their suppliers work together at a global level at which they need to be able to exchange data safely all over the world. The range of vehicles is constantly diversifying while the engineering cycles are becoming ever shorter. Vehicles must be maintained over the entire product life cycle which means that more and more tasks have to be completed in an ever shorter time.
