Challenge: Ensuring robust software and hardware integration 

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. 

Solution: Comprehensive design and verification 

Endego provided a complete solution by designing, verifying, and configuring key hardware and software components. We implemented and tested the following: 

  • Boost converter (LM5122): Ensured a stable 36V power supply through hardware design and testing. 
  • Programmable current sources (TPS92518): Designed and configured for optimized power management. 
  • SPI communication driver: Implemented a driver to manage communication across the system. 
  • LED matrix drivers (TPS92664): Designed and configured programmable drivers for matrix control. 
  • Gaussian brightness distribution: Implemented across the LED matrix to ensure the desired light beam. 
  • CAN FD communication: Verified communication between hardware and software. 
  • Dynamic power derating: Implemented protection from overheating through real-time current and temperature management. 
  • External cooling fan control: Designed hardware control for an auxiliary cooling system. 

Technologies 

  • ASPICE, Embedded C, CAN_FD, SPI, UART, ADC, Boost DC-DC Converters, Programmable Current Sources

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.

How Rolling Stock OEMs Can Reduce Prototype Risk with CAE 

Rolling stock OEMs can reduce prototype risk by defining the validation scope early, connecting design with FEM analysis, checking critical joints and interfaces, and preparing traceable evidence before manufacturing begins. Simulation does not remove the need for physical testing. It helps make the prototype a confirmation of a mature design rather than the first place where major structural weaknesses are discovered.

Electric Motors in Vehicles: How to Design an Efficient and Reliable E-Drive System 

An electric motor is only one component of a vehicle’s e-drive system. Efficiency, range, performance and durability depend on the combined operation of the motor, inverter, battery, battery management system (BMS), cooling system, transmission, control software and mechanical integration. Electric powertrain development should therefore address the complete system and the vehicle’s real operating profile from the outset.
