It is understood that the control unit 301 is configured to obtain an operating condition of the engine 103 and control the opening of the at least one control valve according to the operating condition of the engine 103.

According to an embodiment of the invention, the control unit 301 is adapted to controlling the water pump 102 to be activated to circulate the coolant of the engine 103 through the turbocharger 201 and the engine oil cooler 202 during a warm-up condition.

Specifically, as shown in fig. 3 and 5, in the warm-up condition, the control unit 301 controls the water pump 102 to start, the coolant flowing out from the water outlet of the engine 103 has a certain temperature due to the absorption of heat generated by the engine 103 during operation, when the coolant flows through the turbocharger 201 in the first circulation loop, the waste heat generated by the turbocharger 201 is absorbed to further increase the temperature, the heated coolant circulates through the water pump 102 to reenter the engine 103, the engine body can be heated and heated, and the next circulation is started.

That is to say, under the warm-up condition, under the effect of water pump 102, the coolant forms the quick warm-up small cycle through engine 103, turbo charger 201 in the first circulation circuit and engine oil cooler 202 in the second circulation circuit, and in the system small cycle in-process, the waste heat that the coolant can recycle when engine 103 and turbo charger 201 work produced realizes heating the engine organism and rising the temperature, improves oil spout and burning, and then heats engine oil, helps the engine establish lubrication fast, reaches quick warm-up, improves the purpose of emission, realizes low temperature quick cold start.

According to an embodiment of the present invention, the control unit 301 is configured to control the first control valve 206 and/or the second control valve 207 to open and control the water pump 102 to start to circulate the coolant of the engine 103 through the warm air core 203 and/or the transmission oil cooler 204 during the heating operation.

Specifically, as shown in fig. 3 and fig. 6, in the heating condition, that is, after the engine 103 is warmed up, the control unit 301 controls the first control valve 206 and/or the second control valve 207 to open, so as to conduct the third and/or fourth circulation loops, and controls the water pump 102 to start, the coolant flowing out from the water outlet of the engine 103 enters the third circulation loop and/or the fourth circulation loop, the warm air core 203 in the third circulation loop can use the heat in the coolant to heat the passenger compartment, the heat in the coolant can be used to heat the transmission oil cooler 204 in the fourth circulation loop to an optimal temperature, so that the transmission oil cooler 204 can quickly establish lubrication, and oil saving is achieved, the coolant flowing through the warm air core 203 and the coolant flowing through the transmission oil cooler 204 pass through the second ports of the third and fourth circulation loops connected together, The outlet of the water pump 102 is returned to the water pump 102 to begin the next cycle.

In some embodiments of the present invention, the control unit 301 may adjust the opening degree of the first control valve 206 in real time according to the temperature of the coolant entering the third circulation circuit and the required temperature of the heater core 203 to meet the temperature requirement of the heater core 203. Wherein the temperature of the coolant entering the third circulation circuit can be obtained by a temperature sensor provided in the third circulation circuit, and the required temperature of the warm air core 203 can be preset in the control unit 301. For example, when the temperature of the coolant entering the third circulation circuit is greater than the required temperature of the heater core 203, the control unit 301 may control the opening degree of the first control valve 206 to become smaller; when the temperature of the coolant entering the third circulation circuit is less than the required temperature of the warm air core 203, the control unit 301 may control the opening degree of the first control valve 206 to be increased; when the temperature of the coolant entering the third circulation circuit is equal to the required temperature of the warm air core 203, the control unit 301 may control the opening degree of the first control valve 206 to be constant.

Similarly, the control unit 301 may adjust the opening of the second control valve 207 in real time according to the temperature of the coolant entering the fourth circulation loop and the required temperature of the transmission oil cooler 204 to meet the temperature requirement of the transmission oil cooler 204. Wherein the temperature of the cooling liquid entering the fourth circulation circuit is obtained by a temperature sensor arranged in the fourth circulation circuit, and the required temperature of the transmission oil cooler 204 is preset in the control unit 301. For example, when the temperature of the coolant entering the fourth circulation circuit is higher than the required temperature of the transmission oil cooler 204, the control unit 301 may control the opening degree of the second control valve 207 to become smaller; when the temperature of the coolant entering the fourth circulation circuit is lower than the required temperature of the transmission oil cooler 204, the control unit 301 may control the opening degree of the second control valve 207 to be increased; when the temperature of the coolant entering the fourth circulation circuit is equal to the required temperature of the transmission oil cooler 204, the control unit 301 may control the opening degree of the second control valve 207 to be constant.

Specifically, as shown in fig. 3 and 7, when the engine 103 is in a high-load operating condition, the engine generates a large amount of heat, the control unit 301 controls the third control valve 208 to open, so that the fifth circulation loop is turned on, and controls the water pump 102 to start, the coolant with a large amount of heat flowing out from the water outlet of the engine 103 enters the fifth circulation loop, the radiator 205 in the fifth circulation loop radiates heat of the coolant flowing through, and the radiated coolant flows back to the water pump again through the second port of the fifth circulation loop and the outlet of the water pump 102 to start the next circulation.

Therefore, the exhaust manifold can efficiently reduce the exhaust temperature, the exhaust gas can flow to the turbine at lower temperature, the turbocharger is at proper working temperature, higher efficiency is realized, and the energy-saving effect is achieved.

In some embodiments of the present invention, the control unit 301 may adjust the opening degree of the third control valve 208 in real time according to a target temperature of the coolant in the fifth circulation loop. For example, when the current temperature of the coolant in the fifth circulation loop is greater than the target temperature of the coolant in the fifth circulation loop, the control unit 301 may control the opening degree of the third control valve 208 to be increased; when the current temperature of the coolant in the fifth circulation circuit is less than the target temperature of the coolant in the fifth circulation circuit, the control unit 301 may control the opening degree of the third control valve 208 to become small; when the current temperature of the coolant in the fifth circulation circuit is equal to the target temperature of the coolant in the fifth circulation circuit, the control unit 301 may control the opening degree of the third control valve 208 to be constant. Wherein the current temperature of the cooling liquid in the fifth circulation loop may be obtained by a temperature sensor provided in the fifth circulation loop, and the target temperature of the cooling liquid in the fifth circulation loop may be preset in the control unit 301.

It should be noted that, when the engine 103 is in a high-load condition, the first control valve 206 and the second control valve 207 are selectively opened to perform corresponding functions.

Alternatively, as an example, as shown in fig. 7, in a heating condition, that is, after the engine is warmed up, the control unit 301 may control the first control valve 206, the second control valve 207, and the third control valve 208 to be opened, and under the action of the water pump 102, the coolant forms a rapid warm-up small cycle through the engine 103, the first circulation circuit and the turbocharger 201, the second circulation circuit, and the engine oil cooler 202, so that heat exchange with the turbocharger 201 and the engine oil cooler 202 is realized. Meanwhile, the coolant forms a warm air loop through the engine 103, the third circulation loop of the thermal management module 104 and the warm air core 203, so that heat exchange with the interior of the vehicle through the warm air core 203 is realized, and the coolant forms a transmission oil cooler loop through the engine 103, the fourth circulation loop and the transmission oil cooler 204, so that heat exchange with the transmission oil cooler 204 is realized. Meanwhile, the coolant forms a heat dissipation loop through the engine 103, the fifth circulation loop, and the radiator 205, thereby achieving heat exchange with the external environment through the radiator 205.

In addition, after the engine 103 is stopped, the first control valve 206 can be controlled to be opened, the water pump 102 is controlled to be opened, so that the water pump 102 drives the cooling liquid to flow to the turbocharger 201 and the heater core 203, and the waste heat in the second circulation loop can be utilized to perform internal heat exchange on the heater core 203 in the third circulation loop, so that cooling heat exchange is realized.
