Endego recently tackled a complex project involving software analysis and implementation for front car lights. This case study outlines how we supported the customer in achieving precise software and hardware integration for a new headlamp.
The customer needed assistance in implementing and verifying software on a new headlamp hardware (PCB board). The tasks included checking power and temperature conditions, implementing software protections, and ensuring communication between the light module and car ECU.
Endego provided a complete solution by designing, verifying, and configuring key hardware and software components. We implemented and tested the following:
Endego’s innovative solutions ensured a seamless hardware-software integration by addressing key aspects of the front car lighting system. Through the use of automotive protocols like CAN FD, SPI, and programmable current sources, we optimized both power management and communication between the light module and the car’s ECU. Dynamic testing allowed us to configure thermal protections, such as dynamic power derating, ensuring the system could handle temperature fluctuations. By designing and validating each component, including LED matrix drivers and external cooling controls, we provided robust protection and maintained optimal performance, even under demanding conditions.

In the automotive industry, production decisions are made much earlier than when the line is commissioned. How we design the product, the documentation, the tools and the validation process affects the implementation cost, the timeliness of the SOP and the subsequent scalability of production.

Read moreThe car headlamp is no longer just a lamp. Today, it is one of the most complex technological systems in a vehicle. It combines optics, mechanics, electronics, thermodynamics, sensors, software, type approval and design. It is designed to illuminate the road, assist the driver, react to the surroundings, work in conjunction with other vehicle systems and build brand recognition.
