Our client, world leader in the design and production of driver information displays. With decades of experience the company improves the driving experience through state-of-the-art HMI. Headquarterd in Japan, and with offices around the world, the company delivers solutions to the world’s largest high-end car manufacturers.

the challenge

The tester and developer teams of our client required support in the field of automotive industry software development, with regard to technologies and processes.

A polish branch of an international company required a partner with competencies in creating software and conducting high-quality unit tests, as well as Human-Machine Interfaces (HMI). Our task was to support the client’s teams working on developing and testing software for various types of head-up displays (HUD) in luxury cars by British, Japanese, German, and Swedish manufacturers.

the solution

Developing functional HMI tests and implementing the functionality in the system.

Solwit has developed complex systems of the highest security levels for years. Our experience in projects regarding the railway industry and diligence in adhering to standards convinced our client to include us in the HUD project.


The client’s project was joined by a team of three Solwit engineers specializing in the automotive industry. They possessed unique competencies and were highly experienced in producing embedded, safety-critical software. Their knowledge and skill filled gaps in the client’s team competence but also provided consulting support, such as recommendations for processes and activities facilitating development and testing of the HUD software. At the same time, the Solwit team adopted the internal work culture established by the client, based on certain tools and internal processes.

the effect

Safe and efficient embedded software for the Head-Up Display including documentation provided on time.

In cooperation with the client, the Solwit team developed selected functionalities for the HUD platform. It also took part in creating the architecture for certain functionalities, developing tests, and preparing the testing infrastructure. We produced both unit and HMI tests, and their development processes were properly documented.
