Abstract:
1. A method for controlling a power train of a vehicle, comprising: placing two cooling circuits that operate in a normal way, a first one of the cooling circuits associated with a combustion engine and a second one of the cooling circuits associated with at least one electric member, in fluidic communication by at least one valve in a first position; detecting a temperature of fluid circulating in the first one of the cooling circuits; adjusting, when the temperature in the first one of the cooling circuits rises above a first predetermined threshold, the at least one valve to a second position in which the fluid circulating in the second one of the cooling circuits does not circulate in the first one of the cooling circuits such that the fluid in the second one of the cooling circuits does not cool the combustion engine; and adjusting, when the temperature of the fluid in the first one of the cooling circuits rises above a second predetermined threshold that is hotter than the first predetermined threshold, the at least one valve to a third position in which the fluid arriving in the second one of the cooling circuits from the first one of the cooling circuits is conveyed through an electronics radiator in the second one of the cooling circuits before returning to the first one of the cooling circuits.
