It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0024] Currently, the control of the intercooler fan and the intake heater grid on the passenger car is separate and individual control, and multiple controlled relays and different control pins are required for the two parts, which increases the cost of the electronic control unit and causes resource waste.

[0025] Therefore, as Figure 1 shown, the embodiment of the present application provides an integrated control circuit of an electronic control unit, which comprises a relay 2 connected with an electronic control unit 1, an intake heater grid control module 3 and an intercooler fan control module 4 connected with the relay 2, and the intake heater grid control module 3 and the intercooler fan control module 4 are arranged in parallel.

[0026] Since the intake heater grid control module 3 and the intercooler fan control module 4 cannot be turned on at the same time, based on the characteristic that the two do not work in cross, the intake heater grid 31 and the intercooler fan 41 are connected in parallel to one relay 2, so that one relay 2 is also connected with only two pins of the electronic control unit 1; the separate control of the intake heater grid 31 and the intercooler fan 41 can be realized, and at the same time, the use of the relay 2 and the occupation of the pins of the electronic control unit 1 can be reduced, the pin resources can be reduced, and the cost can be reduced.

[0027] As an optional embodiment, the intake heater grid control module 3 comprises the intake heater grid 31 and the first control switch 32 arranged in series.

[0028] As an optional embodiment, the first control switch 32 is a temperature control switch.

[0029] Specifically, as shown in Figure 2 the intake heater grid control module 3 comprises the intake heater grid 31 and the first control switch 32 arranged in series, i.e. the first control switch 32 controls the switch of the intake heater grid 31 alone.

[0030] As an optional embodiment, the first control switch 32 is configured to be open when the temperature is greater than a first preset value, and to be closed when the temperature is less than the first preset value.

[0031] As an optional embodiment, the intercooler fan control module 4 comprises the intercooler fan 41 and the second control switch 42 arranged in series.

[0032] As an optional embodiment, the second control switch 42 is a temperature control switch.

[0033] As an optional embodiment, the second control switch 42 is configured to be open when the temperature is less than a first preset value, and to be closed when the temperature is greater than the first preset value.

[0034] By virtue of the characteristics that the intake heater grid 31 is used only when the ambient temperature is lower than 0℃, and the intercooler fan is controlled only when the ambient temperature is greater than 0℃, and the two do not work at the same time, a working circuit for controlling the intercooler fan 41 and the intake heater grid 31 is designed by sharing a control pin, thereby reducing the pin resources and lowering the cost.

[0035] As an optional embodiment, the relay 2 is a four-angle relay.

[0036] As an optional embodiment, the four-angle relay comprises a 30 pin, an 85 pin, an 86 pin and an 87 pin, the 85 pin and the 86 pin are connected to the first pin and the second pin of the electronic control unit 1 respectively, the 30 pin and the 87 pin are connected to two ends of the intake heater grid control module 3 respectively, and the 30 pin and the 87 pin are also connected to the intercooler fan control module 4 respectively.
