Abstract
A cooling system for a hybrid powertrain of a motor vehicle comprising an internal combustion engine and an electric traction assembly, comprising a main circuit that can be traversed by a coolant in order to cool the internal combustion engine to a first temperature level and a secondary circuit that can be traversed by a coolant to cool the electric traction assembly to a second temperature level, lower than the first level, each of the circuits and comprising a radiator capable of cooling the coolant by means of heat exchange with an air flow, at least one hydraulic pump for circulating the coolant in the coolant circuits, and one electronic control unit capable of controlling the hydraulic pumps. The control unit comprises a module for recovering information on the dynamics of the vehicle and a module for controlling the flow from the hydraulic pumps on the basis of that information.
