Ecu

The main control functions are:

• Complete torque management, Magneti Marelli has been producing a system based on torque control with three-level supervision since 1999
• Blend control
• Ignition management
• Management of swirl/tumble actuators (flaps and variable geometry)
• Turbo boost management (turbocharger and/or volumetric compressor)
• Fuel composition and volatility recognition
• Valve opening management (VVA- Variable Valve Actuation, VVT- Variable Valve Timing)
• EGR (Exhaust Gas Recirculation) management
• Control of polluting gas emission according to regulations in force in the different countries where the products are marketed; catalytic converter activation and control strategies
• Control of CO₂  emissions (fuel consumption management)

The hardware component of the Electronic Control Unit (ECU) is designed to allow excellent architectural flexibility, resulting in optimized performances depending on the application (2/4/6-cylinder engines).

In fact, the hardware structure can be adapted to the various engine/vehicle configurations through a “scalar” approach, thanks to which it is possible to start from a full version of the same logic core to arrive at reduced versions for simpler vehicles or for different market needs.

The specific management software for Port Fuel Injection (PFI) engines is developed through a design based on:

• Modular type, model-based software architecture for a reutilization that crosses over different applications
• Automatic generation and optimization of the software code
• SPICE 2 certified development process
• AUTOSAR compliant
• ISO 26262 compliant
• Pre-calibration in a simulated environment
• Immobilizer
• Management of communication protocols: CAN, LIN, K line

The Time-to-Market is reduced thanks to fast prototyping which also allows customization according to the customer’s requests.

Magneti Marelli supplies “turnkey” systems, in other words systems that are completely optimized from the calibration standpoint thanks to full and specific skills developed over the last decades at different facilities located in Europe, China, United States, India and South America where, thanks to the necessary competences, systems are developed depending on the different needs of the markets.
