ECU Projects for Your Small Series Production

The development of small series productions is no less time consuming than development of large series. Due to the small quantities involved, costs play an even greater and more sensitive role. At the same time, the quality must meet your standards. With Vector you have a competent and reliable partner that will implement small production run projects together with you.

  • Everything from one source – basic software, ECU, and all project work
  • Drivers and standard software are available that are perfectly tuned to the ECUs
  • Series hardware qualification per Vector Standard based on ISO 16750 / LV124
  • Separate platforms for Automotive (12 V) and Commercial Vehicles (24 V)
  • Series production, support, and maintenance
  • Faster "time to market" when using the same ECU family in follow-up projects


The development of small production runs is no less time consuming than development of large series. Due to the small quantities involved, costs play an even greater and more sensitive role. At the same time, the quality must meet your standards. With Vector you have a competent and reliable partner that will implement small production run projects together with you.

On the basis of the VC family, we create your complete ECU project for small and midget production runs, ranging from the requirements analysis and implementation to series production support. The VC family provides a variety of communication interfaces such as CAN, LIN, FlexRay, Ethernet, and Power Line Charging for eMobility according to ISO 15118 as well as support of various sensor buses and load drivers. For this reason, it is an ideal basis for gateway applications, domain controllers and special functions.

You can use all available Vector controllers directly for commissioning this project. The individual hardware function blocks offer a wide range of application, scalability, and a high level of reuse.

Does our existing portfolio fail to meet your requirements? On the basis of the VC family, we create customized ECU to your exact specifications.

High quality must also be met for small and midget production runs. The Vector Process Management System (VPMS) is an ISO9001:2008 certified process. It guarantees a uniform workflow across all projects and ensures its quality.

The Quality Management, which is independent of the project, checks the progress of the project during software and hardware development in order to guarantee the maximum possible quality standard. If necessary, the process can be adapted to your specific requirements, thereby providing maximum flexibility.

Special attention is paid in every ECU project to the integration of the standard software on the respective ECU. Our many years of experience have made us a strong partner in assisting you with this. Starting with the ECU-specific communication databases and diagnostic descriptions as well as the integration of the Flash bootloader to the partial or complete application integration and development. You can fully rely on our engineers for this.

To ensure error-free operation, we test the integrated component interfaces against one another. This is done firstly on the software side. Secondly the interface to the ECU hardware is tested in detail.

Show more


Not just the components among themselves that have to be tested for high-quality software. Rather, the functionality of the overall system must also be tested. We conduct the prequalification of the ECUs in our in-house labs.

  • Function tests are performed based on an agreed-upon specification.
  • Communication is tested based on CANoe.
  • Diagnostics is tested with CANoe.DiVa.
  • The VT System is used to check the hardware interfaces.
  • Other test options include service life simulation facilities, climatic chambers, and load attachments.

We conduct the series qualification in an accredited, external test lab.

We document the system that is successfully validated and released for the series according to your requirements. We deliver this to you as an initial functional model or for the series depending on the desired stage. The delivery takes place from Vector or our EMS service partner. Alternatively, you are welcome to use your preferred ECU supplier.

Vector provides you with series production support even after series start-up. This includes the monitoring of utilized components and any discontinuation announcements and related new production data sets.
