SYSTEM FOR CONTROLLING THE THERMAL ENERGY OF A MOTOR VEHICLE ENGINE BY ADJUSTING THE FLUID ACTUATORS OF SAID SYSTEM

摘要

The inventive system comprises a high-temperature circuit (12) through which a high-temperature heat carrier fluid runs and which integrates a cooling radiator (22) in which a cooling fluid (46) flows, a low-temperature circuit (14) through which a low-temperature heat carrier fluid runs and which integrates a cooling radiator (30) in which the cooling fluid (46) flows, the pumps (16, 28) of the high-and low temperature circuit forming first actuators for running the heat carrier fluid though the circuits (12, 14) and second actuators for (48) for flowing the cooling fluids (46) in the high- and low-temperature radiators (22, 30), sensors (56, 58, 66, 68) for detecting representative parameters of the cooling requirements of the high-and low temperature circuits and for transmitting said parameters to a control unit (60). Said transmitted parameters comprise at least one parameter related to the first actuators (16, 28) and at least one parameter related to the second actuators (48) and the control unit (60) adjusts the first and second actuators according to said parameters.
