Software Development

One of our core competences is software development for products, electric drives, complete systems and vehicles. This enables us to develop vehicle controls, displays or operating panels completely in-house.

State of the art Software

With our proven expertise in software for vehicle and machine controls, as well as for user interfaces of displays, we efficiently and quickly develop solutions for a wide range of requirements. The machine controller or VCU (Vehicle Control Unit) receives data from all sensors and components installed in the machine and also sends control signals to them. For example, the VCU controls everything from the engine, the heat pump and the chargers to the headlights and taillights. The operator display in the cab is the interface between the machine and the operator and sends the inputs on to the machine control system via the user interface.

Support from A to Z

For safe operation, it is crucial that the machine control and the input display function reliably and are easy to operate. SUNCAR offers programming of both parts from a single source - in accordance with current industry standards, using the state-of-the-art CODESYS software. Following the development, our experts support the commissioning and testing of the machine and ensure flawless operation.

In addition to programming the controllers and displays, we are also happy to take care of the electrical setup with the complete cabling . Furthermore, we can make the machine internet-capable with INSIGHT on request - for simplified service and remote maintenance.
