| 摘要 |
The invention relates to a cooling system for a hybrid drivetrain of a motor vehicle comprising a heat engine (2) and an electric drive unit (3), including a main circuit (10) through which a heat-transfer fluid can pass in order to cool the heat engine (2) to a first temperature level and a secondary circuit (20) through which a heat-transfer fluid can pass in order to cool the electric drive unit (3) to a second temperature level which is lower than a first level, each one of the circuits (10, 20) including a radiator (11, 21) capable of cooling the heat-transfer fluid by heat exchange with a flow of air, at least one hydraulic pump (12, 22, 23, 24) for circulating the heat-transfer fluid in the cooling circuits (10, 20), and an electronic control unit (30) capable of controlling the hydraulic pumps (12, 22, 23, 24). The control unit (30) includes a module for recovering information on the dynamics of the vehicle and a module for controlling the flow rate of the hydraulic pumps (12, 22, 23, 24) according to said information. |
