The increasing complexity of electronic systems in the automotive sector presents development and test departments with ever greater challenges. In addition to functionality, aspects such as connectivity, reliability, and certifiability must also be considered. At the same time, pressure to shorten development cycles and design more efficient tests is growing. Against this background, a new generation of test systems is increasingly coming into focus: compact, well-conceived solutions that can sensibly replace classic test environments in many areas.

Adaptable through well-conceived system design

A central advantage of the system lies in its scalable architecture. Depending on the area of application and testing requirements, different versions are available: from a focused solution for eCall tests to a comprehensive platform for complex test environments including connectivity and other functions.

This concept makes it possible to invest targetedly in the actually required functionality without tying up unnecessary resources. At the same time, the option remains to flexibly expand the test case as requirements grow.

Fast integration of new control units

In practice, designs and requirements for control units change regularly. Classic test systems often reach their limits here, as mechanical adjustments are time-consuming and cost-intensive.

With the CarByte Testbench, all brackets are manufactured using 3D printing. As a result, adjustments can be implemented on short notice – whether for new device types or modified housing shapes. This reduces downtime and ensures a smooth transition between different test objects.

Full functionality with significantly reduced space requirements

Compared to conventional test setups, which are often characterized by large displays, extensive cabling, and massive enclosures, the test case pursues a significantly more efficient approach. All relevant functions are integrated into a compact system, without a reduction in test coverage. The solution is suitable both for laboratory environments and for mobile use.

Efficient transport and immediate operational readiness

A major advantage is shown in transport: The system is designed so that it can be carried as cabin baggage on commercial flights. This eliminates additional costs and risks usually associated with shipping bulky test systems. It also reduces the risk of baggage loss, since no checked baggage is required.

Particularly for international projects or short-notice deployments, this enables significantly faster availability on site.

Support for certification processes

All necessary test cases for relevant certifications can be carried out directly with the test case. A separate infrastructure is not required, which simplifies and accelerates the entire testing process.

Intelligent control and global accessibility

An integrated single-board computer handles the central control of the system and significantly expands the testing possibilities.

The most important functions include:

• Remote access to the test environment

• Automated and repeatable test procedures

• Autonomous operation without permanent user interaction

In addition, an integrated LTE module ensures that the system remains accessible worldwide, independent of local network infrastructure. Tests can thus be started, monitored, and evaluated from any location.

Practical suitability in the vehicle

For tests under real conditions, the test case can be securely fastened in the vehicle. An integrated Isofix mount enables stable installation on the rear seat, allowing driving tests to be carried out simply and without extra equipment.

This particularly facilitates the validation of functions in the real environment of use and increases the reliability of the test results.

Versatile application possibilities beyond automotive

Although the solution was developed specially for automotive applications, its use is not limited to this. Due to its flexible architecture, it is equally suitable for other areas, for example in telecommunications, in the IoT environment, or in the general development of embedded systems.

Our conclusion

The CarByte Testbench combines functionality, flexibility, and practical suitability in a well-conceived overall concept. It reduces organizational and technical effort, accelerates testing processes, and enables significantly more efficient use of resources.

This makes it a compelling alternative to classic test systems – particularly wherever mobility, fast operational readiness, and adaptability are crucial.
