Automotive ECU Development

Our automotive ECU development services involve programming and optimising electronic control units (ECUs) to ensure the safe operations of multiple modules and systems within electric, hybrid, and internal combustion vehicles.

Meeting ECU software development standards, we create lightning solutions, body and chassis control units, and telematics, access, and control systems. Also, we specialise in HVAC system design and hydraulic and pneumatic solutions development.

How ECU Operates

Providing automotive ECU design services, we aim to establish the seamless coordination of hardware and software components, including automotive city mobility solutions.

Receiving data from sensors and using embedded software algorithms, the electronic controllers can perform real-time calculations and decision-making to ensure smooth operation.

It enables coordination between various vehicle systems through CAN, LIN, and automotive Ethernet communication protocols, allowing the optimisation of custom hydraulic solutions and other critical systems.
