In a kind of unshowned improved procedure, reference temperature cylinder head temperature T in other wordsmatThe most measured, but model
Auxiliarily calculated by ECU9.Correspondingly in a kind of improved procedure, eliminate reference temperature sensor 8.
Fig. 2 illustrate by ECU9 implemented according to one embodiment of the present invention for the method running cooling system,
Described method has first step S10, wherein checks whether internal combustion engine starts.If do not started (S10: " N "), then periodically
Ground repeats described inspection.
If internal combustion engine is started (S10: " Y "), then in step S20, check servo valve 3.If checking and drawing servo valve
3 correct operation or work (S20: " N "), send prompting the most in step s 30 and/or limit, especially stop the fortune of internal combustion engine 1
OK.
If ECU9 determines that servo valve 3 correctly works (S20: " Y "), then continue step S40.
ECU makes cooling medium delivery pump 2 run after start-up of the internal combustion engine 1 regularly or presets changeably in this step
, in particular according to temperature, especially ambient temperature, coolant temperature, engine temperature and/or automotive temp preset time period

ECU9 checks whether satisfied first preheating condition in following step S50 subsequently, checks by cooling down for this ECU
The coolant temperature T that media temperature sensor 7 recordscoolWhether less than the first ultimate value T presetthld。
If ECU9 records coolant temperature T in step s 50coolLess than the first ultimate valueThen ECU continuation step S70, and otherwise (S50:, N ") then continues step S60.
In step S60, ECU 9 implements regulation operational mode, in described regulation operational mode, is especially based respectively on pre-
If required theoretical coolant temperature T in other wordsrequestControl cooling medium delivery pump 2 and the regulation rotation of pilot-operated type ground
Turn servo valve 3.
If meeting the first preheating condition (S50: " Y "), then ECU9 switches to the first preheating operation mould in step S70
Formula.
Cooling medium delivery pump 2 does not runs in this step.Bypass conduit and radiator line L2, L3 are in the first preheating fortune
In row mode, the servo valve 3 by being controlled accordingly by ECU9 for this complete switches off.
ECU9 checks whether satisfied second preheating condition in following step S80 subsequently, checks reference temperature for this ECU
