A pilot electronic control unit and a method to derive optimized look up tables

摘要

The invention relates to the field of combustion engines and involves a method and a device for optimizing the look up tables used for combustion control in a test vehicle, the said device being capable of transferring the optimized look up tables to an external device. The device is a pilot electronic control unit forming a closed control loop using operating conditions and look up tables to calculate control signals for the combustion engine to realise a desired pressure in the combustion chamber, measuring the combustion chamber pressure, comparing the desired pressure with the measured pressure and optimising the look up tables to minimize the difference between desired and measured pressure. The pilot electronic control unit transfers the optimized look up tables to an external device which will transfer them to a plurality of standard ECUs used in mass production of vehicles.
