[0023] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work are protected by the present application.

[0024] Under certain circumstances, condensed water will be generated inside the intercooler, which will not only cause problems such as engine misfire and power loss, but may also block the intake pipe or cause the throttle to freeze, seriously affecting driving safety. To address the above problems, related technologies usually use water pumps to reduce the flow of water intercooling, or use valves to control the flow, but these methods are still prone to low-temperature water precipitation or extremely low-temperature freezing.

[0025] In view of this, the present application proposes a control method for the intake system, which can enable the heated coolant to flow through the intercooler for heat exchange, so that the intercooler can be maintained at a higher temperature, avoiding the problem of low-temperature water precipitation or extremely low-temperature freezing in the intercooler.

[0026] In order to illustrate the technical solution of the present application, a specific embodiment is provided below for illustration.

[0027] Figure 1 The following is a schematic diagram of the implementation process of a control method for an intake system provided by an embodiment of the present application, which can be applied to a vehicle. The above-mentioned vehicle can refer to a hybrid vehicle, a pure electric vehicle, a fuel vehicle or other types of vehicles, which is not limited by the present application.

[0028] In an embodiment of the present application, the above-mentioned vehicle may be configured with an intake system, which can be used to supply clean, dry, sufficient and stable air to the engine to meet the needs of the engine, while preventing impurities and large particles of dust in the air from entering the engine combustion chamber and causing abnormal wear of the engine.

[0029] In an embodiment of the present application, the intake system may include a heater and an intercooler.

[0030] The heater can be used to heat the coolant. The heater can be a positive temperature coefficient (PTC) heater or other heaters with heating function, which is not limited in this application.

[0031] The intercooler is used to cool the high-pressure air coming out of the turbocharger in the engine. The intercooler can be a water-cooled intercooler, which is used to cool the air passing through the intercooler by circulating coolant.

[0032] In some embodiments of the present application, Figure 2 As shown, the air intake system may further include a reversing valve, which may be a three-way valve, a four-way valve, etc., which is not limited in the present application. The first end V1 of the reversing valve is connected to the intercooler, and the second end V2 of the reversing valve is connected to the heater. When the first end V1 of the reversing valve is connected to the second end V2 of the reversing valve, the coolant heated by the heater flows through the reversing valve and passes through the intercooler.

[0033] In some embodiments of the present application, the heater may be provided in a heating circuit of a vehicle's heater core. Figure 2 The first end of the heater can be connected to the heater core and the first end of the battery water circuit water pump in sequence, and the second end of the heater is connected to the second end V2 of the reversing valve.

[0034] At the same time, the second end of the battery water circuit pump can be connected to the cooling device (Chiller) and the first end of the battery pack in sequence, and the second end of the battery pack is connected to the second end V2 of the reversing valve. Thus, the coolant can circulate between the battery water circuit pump, the cooling device, the battery pack, the heater, and the heater core to form a heating loop for the battery water circuit and the heater system.

[0035] In some embodiments of the present application, a throttle valve may be provided on the circuit where the intercooler is located to control the coolant flow rate to achieve the purpose of precise control. Specifically, the first end of the intercooler may be connected to the first end V1 of the reversing valve, and the second end of the intercooler may be connected to the throttle valve.

[0036] Combination Figure 2 When the first end V1 of the reversing valve is connected to the second end V2 of the reversing valve, the battery water circuit pump will drive the coolant heated by the heater to the throttle valve, the intercooler, the battery pack and the cooling device.

[0037] In some embodiments of the present application, the third end V3 of the reversing valve is connected to the radiator and the low-temperature circuit water pump. When the first end V1 of the reversing valve is connected to the third end V3 of the reversing valve, the coolant cooled by the radiator is pumped to the intercooler by the low-temperature circuit water pump.

[0038] Specifically, the radiator can be used to cool the coolant, the first end of the radiator can be connected to the third end V3 of the reversing valve, and the second end of the radiator can be connected to the low-temperature circuit water pump.

[0039] The low temperature circuit water pump can be used to pump the coolant after cooling by the radiator to the intercooler. Specifically, the low temperature circuit water pump can be connected to the aforementioned throttle valve, so that the cooled coolant is intercepted by the throttle valve and then flows through the intercooler.

[0040] In addition, the air intake system may also be provided with an electric drive and controller assembly, a first end of which is connected to the third end V3 of the reversing valve, and a second end of which is connected to the low-temperature circuit water pump.

[0041] Combination Figure 2 When the first end V1 of the reversing valve is connected to the third end V3 of the reversing valve, the electric drive and controller assembly is connected in parallel with the intercooler and the throttle valve. At this time, the coolant is driven by the low-temperature circuit water pump, dissipates heat through the radiator, and flows through the intercooler to cool the intercooler.

[0042] It should be noted that the present application does not limit the type of the above-mentioned coolant, nor does it limit the types of various components (such as radiators, low-temperature circuit water pumps, battery water circuit water pumps, etc.).

[0043] Specifically, the control method of the intake system may include the following steps S101 to S103.

[0044] Step S101, obtaining operating parameters of the intake system and environmental information of the vehicle environment.

[0045] The operating parameters refer to the real-time parameters in the intake system during the operation of the intake system, which may include but are not limited to: intake temperature, intake flow, exhaust gas recirculation (EGR) rate. The operating parameters can be measured by sensors inside the intake system or obtained through vehicle controller parameters.

[0046] Environmental information is used to describe the vehicle's environment, including but not limited to: temperature, humidity, weather (such as rain and snow). Environmental information can be measured by the vehicle's sensors or obtained by connecting to the network to obtain information about the vehicle's location.

[0047] Step S102, determining the current dew point temperature according to the working parameters and environmental information.

[0048] The current dew point temperature is the current dew point temperature around the intercooler. The dew point temperature refers to the temperature required for the gaseous water contained in the air to reach saturation and condense into liquid water under a fixed air pressure.

[0049] In the implementation of the present application, the environmental information can reflect the state of the air itself, and the operating parameters of the intake system reflect the impact of the intake system on the air during operation. According to the operating parameters and environmental information, the current air condition around the intercooler can be determined to determine the current dew point temperature.

[0050] Step S103, when the current dew point temperature is less than or equal to the first temperature threshold, controlling the heater to heat the coolant, and controlling the heated coolant to exchange heat with the intercooler.

[0051] In an embodiment of the present application, if the current dew point temperature is less than or equal to the first temperature threshold, it means that there is a risk of low-temperature water precipitation. At this time, the heater can be controlled to heat the coolant, and the heated coolant and the intercooler can be controlled to exchange heat, so that the body temperature of the intercooler and the intake temperature of the intercooler rise, avoiding the generation of condensed water and freezing, and ensuring smooth air intake of the intercooler and normal combustion of the engine.

[0052] In an embodiment of the present application, the current dew point temperature is determined based on the operating parameters of the intake system and the environmental information of the vehicle's environment, and when the current dew point temperature is less than or equal to the first temperature threshold, the heater is controlled to heat the coolant, and the heated coolant is controlled to exchange heat with the intercooler, so that the intercooler can be maintained at a higher temperature, avoiding the problem of low-temperature water precipitation or extremely low-temperature freezing in the intercooler.

[0053] In some embodiments of the present application, determining the current dew point temperature according to the working parameters and the environmental information may include: determining a basic dew point temperature according to the environmental information, and correcting the basic dew point temperature according to the working parameters to obtain the current dew point temperature.

[0054] Specifically, since the temperature, humidity, and weather (such as rain and snow) can reflect the theoretical conditions of the air in the current environment, the basic dew point temperature of the air can be determined according to the environmental information. Exemplarily, a first relationship table between the environmental information and the dew point temperature can be calibrated in advance, and the basic dew point temperature is determined based on the first relationship table.

[0055] The working parameters can reflect the impact of the intake system on the air during operation. Specifically, different working parameters will lead to different impurity content in the air. For example, when the EGR rate increases, the exhaust gas intake accounts for a larger proportion, and the dew point temperature will be higher than the basic dew point temperature of the air in the current environment. Therefore, according to the working parameters, the basic dew point temperature can be corrected to obtain the current dew point temperature of the air, making the dew point temperature more accurate.

[0056] In some embodiments of the present application, controlling the heater to heat the coolant may include: when the current dew point temperature is less than or equal to the second temperature threshold, controlling the heater to heat the coolant to a first target temperature according to a first heating power. When the current dew point temperature is greater than the second temperature threshold, controlling the heater to heat the coolant to a second target temperature according to a second heating power.

[0057] The second heating power is less than or equal to the first heating power, and the second target temperature is less than or equal to the first target temperature.

[0058] In addition, when the current dew point temperature is less than or equal to the second temperature threshold, the battery water circuit water pump can be controlled to operate according to the first duty cycle. When the current dew point temperature is greater than the second temperature threshold, the battery water circuit water pump is controlled to operate according to the second duty cycle, and the second duty cycle is less than or equal to the first duty cycle. In this way, the coolant flow rate can be controlled to achieve a rapid temperature increase effect.

[0059] Correspondingly, controlling the heated coolant to exchange heat with the intercooler may include: controlling the reversing valve to connect the heating circuit of the heater core with the intercooler, so that the heated coolant passes through the reversing valve and exchanges heat with the intercooler.

[0060] Specifically, the second temperature threshold is a preset condensation freezing temperature, which can be used to determine whether there is a risk of icing in the intake system. If the current dew point temperature is less than or equal to the second temperature threshold, it means that there is a risk of condensation freezing. At this time, the heater can be controlled to heat the coolant to the first target temperature at a higher first heating power. For details, please refer to Figure 2 At this time, the reversing valve can be controlled to connect the heating circuit of the heater core with the intercooler, the heater in the heating circuit is turned on, the heating power is the first heating power Q1, and the heater outlet temperature is controlled to reach the first target temperature t1. The heated coolant is pumped through the battery water circuit pump, and passes through the first end V1 and the second end V2 of the reversing valve. It can quickly heat the intercooler body and the intake air, remove the condensed water and ice, and ensure the smooth intake and normal operation of the surrounding components.

[0061] The first temperature threshold is a preset heating temperature, which can be used to determine whether there is a risk of low-temperature water precipitation in the intake system. If the current dew point temperature is greater than the second temperature threshold and less than or equal to the first temperature threshold, it indicates that there is a risk of low-temperature water precipitation. At this time, the heater can be controlled to heat the coolant to the second target temperature at a lower second heating power. For details, please refer to Figure 2 At this time, the reversing valve can be controlled to connect the heating circuit of the heater core with the intercooler, the heater in the heating circuit is turned on, the heating power is the second heating power Q2 (Q2≤Q1), and the heater outlet temperature is controlled to reach the second target temperature t2 (t2≤t1). The heated coolant is pumped through the battery water circuit pump, passes through the first end V1 and the second end V2 of the reversing valve, and quickly heats the intercooler body and the intake air to avoid the generation of condensed water, thereby ensuring smooth intake and normal engine combustion.

[0062] In some embodiments of the present application, after determining the current dew point temperature according to the working parameters and the environmental information, the method may further include: when the current dew point temperature is greater than the third temperature threshold, controlling the low temperature circuit water pump to start and controlling the heater to shut down. The low temperature circuit water pump is used to pump the coolant to the intercooler to cool the intercooler.

[0063] In some embodiments of the present application, when controlling the low-temperature circuit water pump to start, the control method of the intake system may further include: controlling the reversing valve to connect the low-temperature circuit water pump to the intercooler.

[0064] Specifically, the third temperature threshold is a preset heat dissipation temperature, which may be greater than or equal to the first temperature threshold. If the current dew point temperature is greater than the third temperature threshold, it means that the intercooler is operating at a higher temperature. At this time, the low temperature circuit water pump may be controlled to start and the heater may be controlled to shut down, so as to pump the coolant cooled by the radiator to the intercooler to cool the intercooler. For details, please refer to Figure 2 At this time, the heater can be controlled to be turned off, and the coolant is pumped through the low-temperature circuit water pump, through the third end V3 and the first end V1 of the three-way valve, to cool the intercooler body and the intake air to avoid overheating of the intake air and ensure normal combustion of the engine.

[0065] It should be noted that, for the sake of simplicity of description, the aforementioned method embodiments are all expressed as a series of action combinations, but those skilled in the art should know that the present application is not limited to the described order of actions, because according to the present application, certain steps can be performed in other orders.
