A system for optimizing the transmission efficiency of a gearbox 2 of an internal combustion engine 110, and a related method and computer program. The engine 110 is provided with an engine oil circuit 10, the gearbox is provided with a gearbox oil circuit 11 and the system comprises at least one supply channel 3 to supply engine lubricating oil heated by said engine to the gearbox oil circuit 11 to warm the gearbox 2. At least one return channel 4 to return engine lubricating oil to said oil circuit 10 of the engine 110 and pressure control means 6 for regulating the amount of the engine lubricating oil supplied to heat said gearbox 2. Optionally the engine lubricating oil returns to the engine oil circuit 10 through channel 4 under the influence of gravity. The gearbox temperature may be measured by sensors 8 and / or estimated on the basis of mathematical models. |
