Engine intake air temperature control methods, devices and storage media

Abstract

This application discloses a method, device, and storage medium for controlling engine intake air temperature, belonging to the field of vehicle control technology. The method includes: acquiring the temperature of the vehicle's ambient environment; acquiring the vehicle's engine intake air temperature in response to the ambient temperature being lower than a temperature threshold; controlling the speed of the intercooler fan based on the vehicle's engine intake air temperature; and controlling the opening of the intercooler's bypass pipe in response to the engine intake air temperature being lower than a set intake air temperature when the intercooler fan speed is at its minimum controllable speed. The bypass pipe does not cool the gas inside the pipe. This allows some engine intake air to bypass the intercooler and directly reach the engine intake port through the bypass pipe. Because the bypass pipe does not cool the gas inside the pipe, it reduces intercooler efficiency and increases engine intake air temperature, improving the accuracy of engine intake air temperature control while maintaining the overall aesthetics of the vehicle.

Description

Technical Field

[0001] This application relates to the field of vehicle control technology, and in particular to a method, device and storage medium for controlling engine intake air temperature. Background Technology

[0002] In winter, when temperatures are low, the intercooler of a vehicle may become over-efficient in cooling the gas compressed by the turbocharger. This can result in the gas entering the engine after being cooled by the intercooler being too cold, causing problems such as over-boosting of the engine, high fuel consumption, difficulty starting, and incomplete combustion of the fuel mixture, which can lead to misfires.

[0003] In related technologies, the efficiency of the intercooler is reduced by artificially adding obstructions (such as a mask) to the front panel of the car, or the engine intake air temperature is increased by heating the air entering the engine. However, these technologies lack precise control over the engine intake air temperature, and adding obstructions also affects the vehicle's aesthetics. Therefore, how to increase the engine intake air temperature when necessary while maintaining the overall aesthetics of the vehicle is a problem that needs to be solved. Summary of the Invention

[0004] This application provides a method, apparatus, and storage medium for controlling engine intake air temperature, which can be used to increase engine intake air temperature when necessary while maintaining the overall aesthetics of the vehicle. The technical solution is as follows:

[0005] On one hand, embodiments of this application provide a method for controlling engine intake air temperature, the method comprising:

[0006] Obtain the temperature of the vehicle's surrounding environment;

[0007] In response to the ambient temperature of the vehicle being below a temperature threshold, the engine intake air temperature of the vehicle is obtained;

[0008] The speed of the intercooler fan is controlled based on the engine intake air temperature of the vehicle.

[0009] In response to the engine intake air temperature being lower than the set intake air temperature when the fan speed of the intercooler is at the minimum controllable speed, the bypass pipe of the intercooler is opened, and the bypass pipe does not cool the gas inside the pipe.

[0010] On the other hand, an engine intake air temperature control device is provided, the device comprising:

[0011] The first acquisition module is used to acquire the temperature of the vehicle's surrounding environment;

[0012] The second acquisition module is used to acquire the engine intake air temperature of the vehicle in response to the temperature of the environment where the vehicle is located being lower than a temperature threshold.

[0013] The first control module is used to control the speed of the intercooler fan based on the engine intake air temperature of the vehicle.

[0014] The second control module is used to control the bypass pipe of the intercooler to open when the speed of the fan of the intercooler is the lowest controllable speed and the intake air temperature of the engine is lower than the set intake air temperature. The bypass pipe does not cool the gas inside the pipe.

[0015] On the other hand, a non-transitory computer-readable storage medium is also provided, characterized in that the computer-readable storage medium stores a computer program, which is loaded and executed by a processor to implement any of the above-described methods for controlling engine intake air temperature.

[0016] On the other hand, a computer program product is also provided, the computer program product including computer instructions, which, when executed by a processor, implement the steps of any of the above-described engine intake air temperature control methods.

[0017] The technical solution provided in this application brings at least the following beneficial effects:

[0018] This application acquires the engine intake air temperature of the vehicle when the ambient temperature is below a certain threshold. It detects the engine intake air temperature in situations where the low ambient temperature may lead to excessively low engine intake air temperature, facilitating subsequent determination of whether engine intake air temperature control is necessary. Based on the engine intake air temperature, it controls the speed of the intercooler fan. When the engine intake air temperature is too low, it reduces the cooling effect of the intercooler on the engine intake air by decreasing the fan speed. When the intercooler fan speed is reduced to the minimum controllable speed, if the engine intake air temperature is still lower than the set intake air temperature, it controls the opening of the intercooler bypass pipe. This allows some engine intake air to bypass the intercooler and directly reach the engine intake port through the bypass pipe. Because the bypass pipe does not cool the gas inside the pipe, reducing intercooler efficiency, it increases the engine intake air temperature when necessary while maintaining the overall aesthetics of the vehicle.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0026] This application provides a method for controlling engine intake air temperature. Please refer to... Figure 1 The diagram illustrates the implementation environment of the method provided in this application embodiment. This implementation environment may include: an ECU (Engine Control Unit) 11, a first temperature sensor 12, a second temperature sensor 13, a pressure sensor 14, a throttle position sensor 15, a crankshaft position sensor 16, an intercooler fan 17, and a valve 18 for the intercooler bypass pipe.

[0027] Optionally, ECU 11 detects the ambient temperature of the vehicle via the first temperature sensor 12. In response to the ambient temperature being lower than a temperature threshold, ECU 11 detects the engine intake air temperature via the second temperature sensor 13. In response to the engine intake air temperature being lower than a set intake air temperature, ECU 11 controls the speed of the intercooler fan 17 to decrease based on the engine intake air temperature.

[0028] For example, ECU 11 detects the engine boost pressure via pressure sensor 14. ECU 11 detects the vehicle's throttle position via throttle position sensor 15, and the crankshaft rotation speed via crankshaft position sensor 16. Based on the crankshaft rotation speed, ECU 11 calculates the engine speed and then determines the engine load level based on the vehicle's throttle position and engine speed. ECU 11 determines the combustion characteristics and volatility of the engine fuel based on the type of fuel used. Finally, based on the engine boost pressure, engine load level, and the combustion characteristics and volatility of the engine fuel, ECU 11 determines the set intake air temperature.

[0029] In one possible implementation, in response to the engine intake air temperature being lower than the set intake air temperature when the speed of the intercooler fan 17 is at the lowest controllable speed, the ECU 11 controls the valve 18 of the intercooler bypass line to open, wherein the bypass line does not cool the gas inside the line.

[0030] The ECU11, the first temperature sensor 12, the second temperature sensor 13, the pressure sensor 14, the throttle position sensor 15, the crankshaft position sensor 16, the intercooler fan 17, and the valve 18 of the intercooler bypass pipe establish a communication connection through a wired or wireless network.

[0031] Based on the above Figure 1 The implementation environment shown in this application provides a method for controlling engine intake air temperature, such as... Figure 2 As shown, taking the application of this method to an ECU as an example, the method includes steps 201-204.

[0032] In step 201, the ECU obtains the temperature of the vehicle's surrounding environment.

[0033] In one possible implementation, the ECU can detect the temperature of the vehicle's surroundings using a first temperature sensor installed on the vehicle. Optionally, after detecting the ambient temperature, the first temperature sensor converts the ambient temperature into a corresponding first voltage signal. The ECU obtains the first voltage signal from the first temperature sensor and then determines the ambient temperature corresponding to the first voltage signal based on the first voltage signal.

[0034] In step 202, in response to the ambient temperature of the vehicle being below a temperature threshold, the ECU acquires the vehicle's engine intake air temperature.

[0035] In one possible implementation, after acquiring the ambient temperature of the vehicle's surroundings, the ECU compares the ambient temperature with a temperature threshold. If the ambient temperature is lower than the threshold, the ECU activates the engine intake air temperature control function. After the engine intake air temperature control function is activated, the ECU acquires the vehicle's engine intake air temperature, including by detecting the engine intake air temperature using a second temperature sensor installed in the engine intake manifold.

[0036] Optionally, after the second temperature sensor detects the engine intake air temperature, it converts the engine intake air temperature into a corresponding second voltage signal. The ECU obtains the second voltage signal from the second temperature sensor and then determines the engine intake air temperature corresponding to the second voltage signal. For example, after the engine intake air temperature control function is activated, the temperature of the vehicle's ambient environment is continuously monitored. When the ambient temperature is higher than or equal to a temperature threshold, the engine intake air temperature control function is deactivated.

[0037] In step 203, the ECU controls the speed of the intercooler fan based on the vehicle's engine intake air temperature.

[0038] For example, after determining the engine intake air temperature, the ECU controls the speed of the intercooler fan based on the vehicle's engine intake air temperature, including: in response to the vehicle's engine intake air temperature being lower than a set intake air temperature, controlling the speed of the intercooler fan to decrease based on the vehicle's engine intake air temperature.

[0039] In one possible implementation, after determining the engine intake air temperature, it is compared with a set intake air temperature. If the vehicle's engine intake air temperature is lower than the set intake air temperature, the ECU controls the intercooler fan speed to decrease. Optionally, the required reduction in intercooler fan speed can be determined based on the vehicle's engine intake air temperature. For example, target intercooler fan speeds for different engine intake air temperatures can be preset, and the required reduction in intercooler fan speed can be calculated based on the target speed and the current intercooler fan speed. Optionally, it is necessary to ensure that the target speed of the intercooler fan is greater than or equal to the minimum controllable speed of the intercooler fan, wherein the minimum controllable speed of the intercooler fan can be determined based on the intercooler fan model.

[0040] In one possible implementation, the method for determining the set intake air temperature includes, but is not limited to: acquiring the engine's boost pressure, engine load level, and the combustion characteristics and volatility of the engine's fuel; and determining the set intake air temperature based on the engine's boost pressure, engine load level, and the combustion characteristics and volatility of the engine's fuel.

[0041] Optionally, acquiring the engine boost pressure includes: the ECU can detect the engine boost pressure via a pressure sensor installed in the engine's intake manifold. Acquiring the engine load level includes: acquiring the vehicle's throttle position and engine speed; determining the engine load level based on the vehicle's throttle position and engine speed. For example, the ECU can detect the vehicle's throttle position via a throttle position sensor installed at the throttle position, and can detect the crankshaft rotation speed via a crankshaft position sensor installed at the engine crankshaft position, calculating the engine speed based on the crankshaft rotation speed. Optionally, the combustion characteristics and volatility of the engine's fuel can be determined based on the type of fuel.

[0042] For example, after determining the engine's boost pressure, engine load level, and the combustion characteristics and volatility of the engine's fuel, since higher engine boost pressure corresponds to lower engine intake temperature requirements, and higher engine load levels correspond to higher engine intake temperature requirements, and different types of engine fuel combustion characteristics and volatility correspond to different engine intake temperature requirements, the set intake temperature corresponding to different engine boost pressures, engine load levels, engine fuel combustion characteristics and volatility can be determined in advance based on experiments to ensure that the engine works efficiently and that the engine operates in the optimal economic range.

[0043] In step 204, in response to the engine intake air temperature being lower than the set intake air temperature when the intercooler fan speed is at the minimum controllable speed, the ECU controls the intercooler bypass pipe to open, and the bypass pipe does not cool the gas inside the pipe.

[0044] In one possible implementation, after controlling the speed of the intercooler fan, the engine intake air temperature is continuously monitored. In response to the intercooler fan speed being at its minimum controllable speed, and the engine intake air temperature being lower than a set intake air temperature, the ECU controls the intercooler's bypass pipe to open. This bypass pipe does not cool the gas inside the pipe. For example, a bypass pipe is added next to the intercooler, connecting the front intake port to the rear outlet port. When compressed gas enters the bypass pipe, it no longer passes through the intercooler. Here, the front intake port of the intercooler refers to the intake port for the gas before cooling, and the rear outlet port refers to the outlet port for the gas after cooling.

[0045] Optionally, the ECU controls the opening of the intercooler bypass line, including: calculating the difference between the engine intake air temperature and the set intake air temperature; determining the opening degree of the valve of the intercooler bypass line based on the difference; and controlling the valve of the intercooler bypass line to open to the specified degree.

[0046] In one possible implementation, the engine intake air temperature is calculated by subtracting the set intake air temperature from the calculated intake air temperature, and this result is used as the difference between the engine intake air temperature and the set intake air temperature. Optionally, based on the correspondence between the difference between the engine intake air temperature and the set intake air temperature and the opening degree of the intercooler bypass pipe valve, the required opening degree of the intercooler bypass pipe valve is determined. After determining the opening degree of the intercooler bypass pipe valve, the ECU controls the intercooler bypass pipe valve to open to the determined opening degree.

[0047] Optionally, the opening degree of the bypass pipe valve can be one of several preset opening levels. The correspondence between the difference between the engine intake air temperature and the set intake air temperature and the opening degree of the intercooler bypass pipe valve can be determined experimentally. For example, the flow rate of gas allowed through the valve can also be controlled by a PWM pulse signal, and the correspondence between the difference between the engine intake air temperature and the set intake air temperature and the flow rate of gas allowed through the intercooler bypass pipe valve can also be determined experimentally.

[0048] In one possible implementation, after the bypass line of the intercooler is opened, when the valve of the bypass line of the intercooler is opened to its maximum degree, the engine intake air temperature of the vehicle is lower than the set intake air temperature, indicating that the control requirement for the engine intake air temperature cannot be met.

[0049] For example, after the intercooler bypass pipe is opened, the vehicle's engine intake air temperature is continuously monitored. If the engine intake air temperature remains lower than the set intake air temperature even after the intercooler bypass pipe valve is opened to its maximum degree, a message indicating that the engine intake air temperature control requirement cannot be met is displayed. Optionally, the method of indicating that the engine intake air temperature control requirement cannot be met includes, but is not limited to: displaying text information indicating that the engine intake air temperature control requirement cannot be met on the vehicle's center console display screen, or broadcasting voice information indicating that the engine intake air temperature control requirement cannot be met through the vehicle's audio system.

[0050] In one possible implementation, after the intercooler bypass line is opened, the temperature of the vehicle's surrounding environment is continuously monitored, and the valve of the intercooler bypass line is closed in response to the temperature of the vehicle's surrounding environment being greater than or equal to a temperature threshold.

[0051] Combining the above methods and processes, with Figure 3The schematic diagram of an intercooler structure provided in this application is illustrated below. The executing entity can be an ECU (not shown in the diagram). The gas compressed by the turbocharger 302 can be cooled by the fan of the intercooler 303. When the ambient temperature of the vehicle is below a temperature threshold, the ECU obtains the engine intake air temperature. In response to the engine intake air temperature being lower than a set intake air temperature, the ECU controls the fan speed of the intercooler 303 to decrease based on the engine intake air temperature. In response to the engine intake air temperature being lower than the set intake air temperature when the intercooler fan speed is at the minimum controllable speed, the ECU controls the intercooler bypass pipe 304 to open, allowing the gas compressed by the turbocharger 302 to enter the intercooler bypass pipe 304. The intercooler bypass pipe 304 does not cool the gas inside the pipe. The gas output from the intercooler bypass pipe 304 and the intercooler 303 enters the turbocharged engine 301 through the throttle valve 305.

[0052] Combining the above methods and processes, with Figure 4 The following example illustrates a control logic diagram for engine intake air temperature provided in an embodiment of this application. The executing entity can be an ECU. Step 401: The ECU monitors the ambient temperature of the vehicle and the engine intake air temperature. Steps 402 and 403 are function enable calibrations for the scheme. Step 402: When the ambient temperature of the vehicle is lower than the temperature threshold, the engine intake air temperature control function is activated. Step 403: When the ambient temperature of the vehicle is higher than or equal to the temperature threshold, the engine intake air temperature control function is deactivated. Step 404: With the engine intake air temperature control function activated, the engine intake air temperature is primarily controlled by controlling the speed of the intercooler fan. If fan control cannot bring the engine intake air temperature to the set intake air temperature, the engine intake air temperature is controlled through the intercooler bypass pipe. Step 405: The set intake air temperature is determined, and the opening degree of the valve in the intercooler bypass pipe is controlled based on the difference between the engine intake air temperature and the set intake air temperature.

[0053] In this embodiment, when the ambient temperature of the vehicle is below a temperature threshold, the engine intake air temperature is obtained. If the low ambient temperature may lead to excessively low engine intake air temperature, the engine intake air temperature is detected to facilitate subsequent determination of whether control is necessary. Based on the engine intake air temperature, the speed of the intercooler fan is controlled. When the engine intake air temperature is too low, the intercooler's cooling effect on the engine intake air is reduced by decreasing the fan speed. When the intercooler fan speed is reduced to the minimum controllable speed, if the engine intake air temperature is still lower than the set intake air temperature, the intercooler's bypass pipe is opened. This allows some engine intake air to bypass the intercooler and directly reach the engine intake port through the bypass pipe. Because the bypass pipe does not cool the gas inside the pipe, reducing intercooler efficiency, the engine intake air temperature is increased when necessary, while maintaining the overall aesthetics of the vehicle.

[0054] See Figure 5 This application provides an engine intake air temperature control device, which includes:

[0055] The first acquisition module 501 is used to acquire the temperature of the environment where the vehicle is located;

[0056] The second acquisition module 502 is used to acquire the engine intake air temperature of the vehicle in response to the temperature of the vehicle's environment being lower than a temperature threshold.

[0057] The first control module 502 is used to control the speed of the intercooler fan based on the engine intake air temperature of the vehicle.

[0058] The second control module 503 is used to control the bypass pipe of the intercooler to open when the speed of the intercooler fan is at the lowest controllable speed and the engine intake air temperature is lower than the set intake air temperature, so that the bypass pipe does not cool the gas inside the pipe.

[0059] In one possible implementation, the first control module 502 is configured to control the speed of the intercooler fan to decrease based on the vehicle's engine intake air temperature in response to the vehicle's engine intake air temperature being lower than a set intake air temperature.

[0060] In one possible implementation, the second control module 503 is used to calculate the difference between the engine intake air temperature and the set intake air temperature; determine the opening degree of the valve of the intercooler bypass pipe based on the difference; and control the valve of the intercooler bypass pipe to open to the specified degree.

[0061] In one possible implementation, the second control module 503 is also configured to indicate that the engine intake air temperature control requirement cannot be met when the valve of the bypass line of the intercooler is opened to the maximum degree and the engine intake air temperature of the vehicle is lower than the set intake air temperature.

[0062] In one possible implementation, the device further includes a third control module for controlling the valve of the bypass line of the intercooler to close in response to the temperature of the vehicle's ambient environment being greater than or equal to a temperature threshold.

[0063] In one possible implementation, the device further includes: a fourth acquisition module for acquiring the engine's boost pressure, engine load level, and combustion characteristics and volatility of the engine's fuel; and a determination module for determining a set intake air temperature based on the engine's boost pressure, engine load level, and combustion characteristics and volatility of the engine's fuel.

[0064] This device acquires the engine intake air temperature when the ambient temperature is below a certain threshold. It detects the engine intake air temperature in situations where the low ambient temperature might lead to excessively low engine intake air temperature, facilitating subsequent determination of whether temperature control is necessary. Based on this intake air temperature, it controls the intercooler fan speed. When the engine intake air temperature is too low, it reduces the intercooler's cooling effect by decreasing the fan speed. If the engine intake air temperature is still below the set intake air temperature when the intercooler fan speed is reduced to the minimum controllable speed, it opens the intercooler's bypass pipe. This allows some engine intake air to bypass the intercooler and directly reach the engine intake port through the bypass pipe. Because the bypass pipe does not cool the gas inside the pipe, reducing intercooler efficiency, it increases the engine intake air temperature when necessary while maintaining the vehicle's overall aesthetics.
