[0053] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0054] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0055] The main solution of the embodiment of the present application is: when the engine is in the first shutdown state, the electronically controlled valve is controlled to be turned on and off in a preset manner; when the on and off operation of the electronically controlled valve is completed, the working state of the temperature indicator light is adjusted according to the oil temperature collected by the temperature sensor; when the working state of the temperature indicator light is the lit state, the oil level is measured according to the oil dipstick.

[0056] When checking the oil level with the traditional oil dipstick, you must first start the engine and run it for a while to ensure that the oil temperature in the oil pan rises to a certain value, then stop the engine and wait for a while, and then check the oil level in the oil pan through the oil dipstick. Generally, there is no oil temperature sensor on the engine, and the oil temperature cannot be well controlled after the engine is started or stopped. The oil temperature can only be roughly judged by the engine running time or downtime. Therefore, it is generally stipulated how long the engine is started and how long it is stopped before reading the oil dipstick scale. Since the oil temperature is uncontrollable, the oil level reading is very inaccurate. And when the engine is running, the oil pump continuously draws oil from the oil pan, and the oil fills the entire lubricating oil circuit of the engine. The oil after lubricating each oil circuit and oil-using parts returns to the engine oil pan through the cylinder oil return channel, and the oil circulates continuously in this way. When the engine is shut down for a short time, a large amount of oil (about 0.6L or more) is stored in the engine oil channel. At this time, the liquid level scale read by the oil dipstick is L1; after the engine is shut down for a long time (for example, shut down for more than 8 hours), most of the oil in the engine oil channel falls back into the oil pan. At this time, the oil level scale read by the oil dipstick is L2; ​​generally, the difference between L2-L1 is greater than 0.6L, which results in too large a difference in the oil level read by the oil dipstick at different shutdown times.

[0057] To sum up, the traditional oil dipstick reading has a large error, mainly due to the following reasons: 1. First of all, different engine running time, different oil temperature, and large difference in oil density will lead to different oil levels; 2. Different downtime will also lead to large differences in oil levels (the oil level difference between downtime of 5 minutes and downtime of 8 hours is 0.6L); 3. If the customer does not check the dipstick according to the standard operating procedures, the oil level read through the oil dipstick will be too different to have any reference value.

[0058] In the present application, when the solenoid valve is energized, the dipstick tube is connected to the oil pan through the first channel, and when the solenoid valve is de-energized, the dipstick tube is disconnected from the oil pan. At the same time, the engine oil temperature can be obtained in real time through the temperature sensor, and the indicator light will feedback the engine oil temperature. The liquid level measurement is performed when the indicator light is on, thereby ensuring the accuracy of the oil level measurement in the engine oil pan and the repeatability of the measurement results.

[0059] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, an oil level measuring device, etc. The following takes the oil level measuring device as an example to illustrate this embodiment and the following embodiments.

[0060] Based on this, the present application embodiment provides a method for measuring the oil level. Figure 1 , Figure 1 This is a flow chart of the first embodiment of the engine oil level measurement method of the present application.

[0061] In this embodiment, the oil level measurement method is applied to an oil level measurement unit, the oil level measurement unit includes an oil dipstick tube, an oil dipstick, an electric control valve, a temperature sensor and a temperature indicator light, the oil dipstick tube includes a first channel and a second channel, the first channel and the second channel form a U-shaped tube structure, the electric control valve is located in the first channel, the temperature sensor is located at the bottom of the first channel, and the temperature indicator light is located at the top of the oil dipstick tube, the oil level measurement method includes steps S10 to S30:

[0062] It should be noted that the engine Figure 2 As shown, channel 1 is the first channel, channel 2 is the second channel, the engine includes a cylinder oil return channel, an oil pan and an oil level measuring unit, the oil level measuring unit includes a dipstick handle, a dipstick sealing ring, an oil dipstick tube, an oil dipstick, an electric control valve, a temperature sensor and a temperature indicator light, the oil dipstick tube includes a first channel and a second channel, and the first channel and the second channel form a U-shaped tube structure.

[0063] It is understandable that the first channel and the second channel in the oil dipstick tube form a U-shaped tube structure, which ensures that the oil dipstick tube and the oil level in the oil pan are consistent when the first channel and the second channel are connected. At the same time, an electric control valve is arranged in the first channel. When the electric control valve is powered on, the oil dipstick tube is connected to the oil pan through the first channel. When the solenoid valve is powered off, the dipstick tube is disconnected from the oil pan. The electric control valve is electrically connected to the engine control system, and the switch of the electric control valve can be controlled by the engine control system. A temperature sensor is arranged at the bottom of the first channel to measure the oil temperature inside the dipstick tube. A resistance heating wire is arranged at the bottom of the dipstick tube, and the oil in the oil dipstick tube can be heated by the resistance heating wire, and the temperature of the oil in the oil dipstick tube is measured in real time by the temperature sensor. When the oil temperature reaches the target temperature, the resistance heating wire is controlled to stop heating, and the temperature indicator light is controlled to light up. In this embodiment, the oil level cannot be measured when the engine is running, so the electric control valve is not powered on when the engine is running, and the oil pan is not connected to the oil dipstick tube.

[0064] In a specific implementation, the lower opening of the oil dipstick tube is connected to the oil pan through a first channel, and the first channel of the lower opening of the dipstick tube is set below the oil level of the oil pan, and the middle of the oil dipstick tube is also connected to the position above the oil level of the oil pan through a second channel. The oil dipstick is inserted into the dipstick tube, and the head of the oil dipstick has a handle, and the oil dipstick can be pulled out and inserted through the handle of the dipstick. A sealing ring is provided between the head of the dipstick and the dipstick tube to ensure the sealing of the dipstick tube. A steel sheet or steel wire is connected below the head of the dipstick, and the bottom of the dipstick is designed with scale marks for the minimum and maximum liquid levels. Since the middle of the dipstick tube is connected to the part above the oil pan level through the second channel, and the lower end of the dipstick tube is connected to the oil pan through the first channel, it can be seen from the U-tube connection principle that the oil level height inside the dipstick tube is consistent with the oil level height inside the oil pan.

[0065] Step S10, when the working state of the engine is in the first shutdown state, controlling the electronically controlled valve to be turned on and off according to a preset method.

[0066] It should be noted that the first shutdown state refers to the state when the engine changes from running to shutdown. At this time, the engine is just shut down or the shutdown time does not exceed the set shutdown time threshold. The preset method refers to controlling the electric control valve to be powered on after the engine is shut down and to be powered off after a preset delay time. In this embodiment, the preset delay time is set to 1min, and can also be set to other values ​​according to needs, which is not limited in this embodiment. When the working state of the engine is in the first shutdown state, the electric control valve is controlled to be turned on and off according to the preset method.

[0067] In a feasible implementation, step S10 may include steps A11 to A12:

[0068] Step A11, controlling the electric control valve to be powered on, and obtaining the duration of the power-on of the electric control valve.

[0069] Step A12, when the duration of the power-on reaches a preset duration, the solenoid valve is controlled to be powered off.

[0070] It should be noted that when the working state of the engine is in the first shutdown state, the electric control valve is controlled to be energized, and the duration of the energization of the electric control valve is obtained. When the duration of the energization reaches the preset duration, the solenoid valve is controlled to be de-energized. In this embodiment, the preset duration is set to 1 minute, and can also be set to other values ​​according to needs, which is not limited in this embodiment.

[0071] It can be understood that the above-mentioned on-off operation connects the oil pan and the oil dipstick tube for a preset duration after the engine is shut down, and then disconnects the oil pan and the oil dipstick tube, thereby ensuring that the oil return time from the engine is only the preset duration.

[0072] Step S20, when the on-off operation of the electronically controlled valve is completed, adjusting the working state of the temperature indicator light according to the oil temperature collected by the temperature sensor.

[0073] It should be noted that after the electric control valve is powered on and powered off after a preset delay, the on-off operation of the electric control valve is completed. If the oil level in the oil pan needs to be measured at this time, the oil temperature of the oil in the oil dipstick tube is collected by the temperature sensor, and when the oil temperature reaches the requirement, the working state of the temperature indicator light is adjusted to light up the temperature indicator light. In this embodiment, the working state of the temperature indicator light includes but is not limited to the lighting state and the off state.

[0074] In a feasible implementation manner, the oil dipstick tube further includes a resistance heating wire, and the resistance heating wire is located at the bottom of the oil dipstick tube; step S20 may include: steps B11 to B12:

[0075] Step B11, when the oil temperature collected by the temperature sensor is less than a preset temperature threshold, control the resistance heating wire to start heating and obtain the current oil temperature.

[0076] It should be noted that when it is necessary to measure the oil level in the oil pan, if the oil temperature is less than the preset temperature threshold, the resistance heating wire is controlled to heat the oil inside the oil dipstick tube, and the temperature sensor is used to measure the oil temperature inside the oil dipstick tube in real time. In this embodiment, the current oil temperature refers to the oil temperature collected by the temperature sensor in real time during the heating process of the resistance heating wire; the preset temperature threshold value range is 50℃±2℃, and can also be set to other ranges according to needs, which is not limited in this embodiment.

[0077] Step B12, when the current engine oil temperature reaches the preset temperature threshold, adjusting the working state of the temperature indicator light to a lit state.

[0078] It should be noted that when the current oil temperature reaches the preset temperature threshold, the temperature indicator light is controlled to light up, and the working state of the temperature indicator light is adjusted from the off state to the lit state. After the temperature indicator light is lit, the oil level in the oil pan can be read through the oil dipstick, which ensures the consistency of the oil temperature when reading the oil level, thereby ensuring the consistency of the engine oil return time and the oil temperature when reading the oil level each time, and ensuring the accuracy and repeatability of the dipstick reading.

[0079] In a feasible implementation, step S20 may include: steps C11 to C13:

[0080] Step C11, when the oil temperature collected by the temperature sensor is greater than a preset temperature threshold, obtaining the shutdown duration.

[0081] It should be noted that when the engine is in the first shutdown state and the on-off operation of the electronically controlled valve is completed, if the oil temperature collected by the temperature sensor is greater than the preset temperature threshold, the shutdown duration of the engine is obtained.

[0082] Step C12, obtaining the current engine oil temperature when the shutdown duration is longer than the third time interval.

[0083] Step C13, when the current engine oil temperature reaches the preset temperature threshold, adjusting the working state of the temperature indicator light to a lit state.

[0084] It should be noted that when the shutdown duration is longer than the third time interval, the oil temperature collected by the temperature sensor is obtained. In this embodiment, the third time interval can be set to 5 minutes or other values, which is not limited in this embodiment.

[0085] It is understandable that when the shutdown duration is longer than the third time interval, it indicates that the oil temperature has dropped to a certain extent. At this time, it is determined whether the current oil temperature has dropped to the preset temperature threshold. If so, the temperature indicator light is controlled to light up, and the working state of the temperature indicator light is adjusted from the off state to the lit state; if not, the oil temperature is continuously obtained through the temperature sensor until the current oil temperature drops to the preset temperature threshold, and the working state of the temperature indicator light is adjusted. In this embodiment, since the electric control valve is powered off, the oil pan and the dipstick tube are disconnected, the amount of oil in the dipstick tube is small, and the cooling speed is fast. After the temperature indicator light is lit, the oil level in the oil pan is read through the oil dipstick, which can ensure that the engine oil return time and oil temperature are consistent each time the oil level is read, ensuring the accuracy and repeatability of the dipstick reading.

[0086] In a feasible implementation manner, the engine oil level measurement unit further includes a trigger control, and the trigger control is located at the top of the engine oil dipstick; Step S20 may include: Steps D11 to D13:

[0087] It should be noted that a trigger control may also be provided on the oil level measurement unit, located on the top of the oil dipstick. The trigger control may be a physical button or other forms, which is not limited in this embodiment.

[0088] It is understandable that after the user clicks the trigger control, the liquid level measurement function is turned on. At this time, the engine control system measures the oil temperature through the temperature sensor and gives the indicator light feedback status, and determines whether to heat the oil through the resistance heating wire. When the oil temperature reaches the preset temperature threshold T, the heating stops and feedback is given through the indicator light. In this way, the user does not need to distinguish the engine status. When the liquid level needs to be measured, just click the trigger control and wait for the indicator light to light up, and then read the oil level to get an accurate and repeatable liquid level value.

[0089] Step D11, when the on-off operation of the electric control valve is completed, obtaining the operation information of the trigger control.

[0090] Step D12: determining the current functional state of the liquid level measurement function according to the operation information.

[0091] Step D13, when the current functional state is the on state, adjusting the working state of the temperature indicator light according to the oil temperature collected by the temperature sensor.

[0092] It should be noted that when the on-off operation of the electric control valve is completed, the operation information of the trigger control is obtained. The operation information includes a flag bit indicating whether the trigger control is clicked or pressed. In this embodiment, different flag bits correspond to different states of the trigger control. For example, when the flag bit is 1, it means that the trigger control is pressed; when the flag bit is 0, it means that the trigger control is not pressed. This embodiment does not limit the specific meaning of the flag bit.

[0093] It can be understood that when the trigger control is pressed, it means that the user needs to measure the oil level, and the level measurement function is turned on; when the trigger control is not pressed, it means that there is no need to measure the oil level, and the level measurement function is turned off.

[0094] In a specific implementation, whether the trigger control is pressed can be determined according to the operation information, thereby clarifying the current functional state of the liquid level measurement function. In this embodiment, the functional state includes an on state and an off state.

[0095] In a specific implementation, when the current functional state is the on state, a step of adjusting the working state of the temperature indicator light according to the oil temperature collected by the temperature sensor is performed.

[0096] Step S30, when the temperature indicator light is in the on state, measuring the engine oil level according to the engine oil dipstick.

[0097] It should be noted that when the temperature indicator light is in the on state, the oil level is measured using the oil dipstick to ensure the consistency of the oil temperature during each level measurement.

[0098] The present embodiment provides an oil level measurement method, and the method of the present embodiment is applied to an oil level measurement unit, wherein the oil level measurement unit comprises an oil dipstick tube and an oil dipstick, wherein the oil dipstick tube comprises a first channel, a second channel, an electric control valve, a temperature sensor and a temperature indicator light, wherein the first channel and the second channel form a U-shaped tube structure, the electric control valve is located in the first channel, the temperature sensor is located at the bottom of the first channel, and the temperature indicator light is located at the top of the oil dipstick tube; the oil level measurement method comprises: when the working state of the engine is in a first shutdown state, controlling the electric control valve to be turned on and off in a preset manner; when the on and off operation of the electric control valve is completed, adjusting the working state of the temperature indicator light according to the oil temperature collected by the temperature sensor; when the working state of the temperature indicator light is a lit state, measuring the oil level according to the oil dipstick. In the above manner, when the solenoid valve is energized, the dipstick tube is connected to the oil pan through the first channel, and when the solenoid valve is de-energized, the dipstick tube is disconnected from the oil pan. At the same time, the engine oil temperature can be obtained in real time through the temperature sensor, and the indicator light will feedback the engine oil temperature. The liquid level measurement is performed when the indicator light is on, thereby ensuring the accuracy of the oil level measurement in the engine oil pan and the repeatability of the measurement results.

[0099] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 Before step S10, the oil level measurement method further includes steps S01 to S03:

[0100] Step S01, obtaining the operating information of the engine within a preset time period.

[0101] It should be noted that the operation information of the engine within the preset time period from the current moment is obtained. In this embodiment, the operation information includes relevant information such as the operation speed, operation time, and downtime. For example, if the current moment is 14:00:00 and the preset time period is 15 minutes, the operation information within the time period of 13:45:00 to 14:00:00 is obtained.

[0102] Step S02: determining the shutdown time of the engine according to the operation information.

[0103] Step S03: when the shutdown time is less than the first time interval, determining that the working state of the engine is a first shutdown state.

[0104] It should be noted that the engine downtime is determined based on the operation information. When the downtime is less than the first time interval, the engine working state is determined to be the first downtime state, indicating that the engine is just stopped or the downtime does not exceed the set first time interval. In this embodiment, the first time interval can be set to 2 minutes or other values, and this embodiment is not limited to this.

[0105] In a feasible implementation manner, the oil dipstick tube further includes a resistance heating wire, and the resistance heating wire is located at the bottom of the oil dipstick tube; after step S02, steps E11 to E14 may be included:

[0106] Step E11, when the shutdown time is not less than a second time interval, determining that the working state of the engine is a second shutdown state, and the second time interval is greater than the first time interval.

[0107] It should be noted that when the downtime is not less than the second time interval, it means that the engine has been stopped for a long time without starting, and the working state of the engine is the second downtime state. In this embodiment, the second time interval can be set to 30 minutes or other values, and this embodiment is not limited to this.

[0108] Step E12, controlling the resistance heating wire to start heating according to the second shutdown state, and obtaining the oil temperature collected by the temperature sensor in real time.

[0109] Step E13, adjusting the working state of the temperature indicator light according to the engine oil temperature.

[0110] Step E14, when the temperature indicator light is in the on state, measuring the engine oil level according to the engine oil dipstick.

[0111] It should be noted that, when the engine is just stopped, the electric control valve has been powered on for a preset duration and then powered off. At this time, the oil in the oil dipstick tube is also the amount of oil after the engine returns for a preset duration, but the oil temperature is low. At this time, it is only necessary to control the resistance heating wire to heat the oil in the oil dipstick tube, and obtain the oil temperature collected by the temperature sensor in real time. When the oil temperature reaches the preset temperature threshold, the temperature indicator light is controlled to light up, and the working state of the temperature indicator light is adjusted from the off state to the lit state. At this time, the oil level is measured through the oil dipstick. This ensures that the engine return time and oil temperature are consistent each time the oil level is read, ensuring the accuracy and repeatability of the dipstick reading.

[0112] This embodiment provides a method for measuring the oil level, which obtains the operation information of the engine within a preset time period; determines the downtime of the engine according to the operation information; and determines that the working state of the engine is the first downtime state when the downtime is less than the first time interval. In this way, the working state of the engine can be accurately judged, laying a foundation for the subsequent measurement of the oil level.

[0113] For example, in order to help understand the implementation process of the oil level measurement method obtained by combining this embodiment with the above-mentioned embodiment 1, specifically:

[0114] The oil level measurement method of this embodiment adopts an oil level measurement unit. The oil level measurement unit includes a gauge tube provided with a channel 1 and a channel 2 to form a U-shaped tube structure, which ensures that when the channel 1 and the channel 2 are connected, the oil gauge tube and the oil level in the oil pan are at the same height. An electric control valve is provided in the channel 1. When the electric control valve is powered on, the gauge tube is connected to the oil pan through the channel 1. When the solenoid valve is powered off, the gauge tube is disconnected from the oil pan. The electric control valve is electrically connected to the engine control system, and the switch of the electric control valve can be controlled by the engine control system. A temperature sensor is provided at the bottom of the channel 1 to measure the oil temperature inside the gauge tube. A resistance heating wire is provided at the bottom of the gauge tube, and the oil in the gauge tube can be heated by the resistance heating wire, and the temperature of the oil in the oil gauge tube can be measured in real time by the temperature sensor. When the oil temperature reaches the target temperature, the resistance heating wire is controlled to stop heating, and feedback is given through the indicator light, and then the oil level is read, which is an accurate and repeatable level value.

[0115] In addition to the above-mentioned oil level measurement unit, the oil level measurement method of this embodiment can also use Figure 4In the oil level measuring unit shown in the figure, the lower opening of the oil dipstick tube is connected to the oil pan through channel 1, and the channel 1 with the lower opening of the dipstick tube is arranged below the oil level of the oil pan, and a temperature control valve is arranged on the channel 1. The middle part of the oil dipstick tube is also connected to the position above the oil level of the oil pan through channel 2. The oil dipstick is inserted into the dipstick tube, and the head of the oil dipstick has a handle, and the oil dipstick can be pulled out and inserted through the handle of the dipstick. A sealing ring is arranged between the head of the dipstick and the dipstick tube to ensure the sealing of the dipstick tube. A steel sheet or steel wire is connected below the head of the dipstick, and the bottom of the dipstick is designed with scale marks of the minimum and maximum liquid levels. Since the middle part of the dipstick tube is connected to the part above the oil pan level through channel 2, and the lower end of the dipstick tube is connected to the oil pan through channel 1, channel 1 and channel 2 form a U-shaped tube structure, which ensures that the oil level height of the oil dipstick tube and the oil pan is consistent when channel 1 and channel 2 are connected. A temperature control valve is set in channel 1. Assuming that the initial opening temperature of the temperature control valve is T1 (for example, set to 40°C), the fully open temperature of the temperature control valve is approximately T1+10°C, and the fully closed temperature of the temperature control valve is approximately T1-3°C (hysteresis of the temperature control valve). In addition, an indicator light for the temperature control valve status is set at the head of the oil dipstick tube. When the temperature control valve is closed, the indicator light of the temperature control valve at the head of the dipstick tube is also off; when the temperature control valve is initially opened, the indicator light of the temperature control valve at the head of the dipstick tube is red; when the temperature control valve is fully opened, the indicator light of the temperature control valve at the head of the dipstick tube is blue.

[0116] When using the measuring device corresponding to the temperature control valve to measure the liquid level, there are mainly three scenarios. The measurement process in each of the following scenarios is as follows: 1. When the engine is in a cold state, such as Figure 5 As shown, the user needs to check the oil level: first open the engine hood and start the engine. At this time, the temperature control valve indicator light on the head of the dipstick tube should be in the off state. The engine starts and runs for a period of time until the temperature control valve is initially opened (about 4 minutes of operation, the oil temperature can rise from normal temperature to above 40°C), the indicator light is red, and at this time, channel 1 and channel 2 form a U-shaped tube, and the oil level in the dipstick tube is kept consistent with that in the oil pan. At this time, the oil temperature is greater than 40°C. Continue to run the engine until the temperature control valve is fully opened (about 2 minutes, the oil temperature rises to 50°C), and the indicator light is blue. Then control the engine to stop and wait (about 5 minutes) for the temperature control valve to be fully closed (due to the hysteresis of the temperature control valve, the fully closed temperature is about 37°C), the indicator light goes out, and the oil level in the oil pan can be read through the oil dipstick. Since the oil temperature is about 37℃ at this time, the downtime is also controllable (about 5 minutes), and the amount of oil returning to the oil pan through the oil return channel is controllable, so the oil level read by the oil dipstick is controllable. It can ensure that the oil level read each time is consistent, and then the accuracy of the dipstick reading can be guaranteed by calibrating the scale.

[0117] 2. When the engine is running, turn it to shutdown, such as Figure 6 As shown, the user needs to check the oil level: first open the engine hood, then observe the temperature control valve indicator light on the dipstick tube head. If the temperature control valve indicator light is red or off, you need to start the engine until the temperature control valve indicator light is blue and then control the engine to stop, and then wait until the temperature control valve indicator light is off to accurately read the oil level through the oil dipstick. If the temperature control valve indicator light is blue, the oil temperature in the engine oil pan is greater than the temperature of the temperature control valve fully open, but the accurate temperature of the oil cannot be determined, and the engine shutdown time cannot be controlled. Therefore, wait for the temperature control valve indicator light to go out, then start the engine until the temperature control valve light is blue and then control the engine to stop, and then wait until the temperature control valve indicator light goes out to accurately read the oil level through the oil dipstick.

[0118] 3. If the engine is shut down for a long time, for example, before starting the engine the next morning, the temperature of the thermostatic valve when the engine was shut down last time was about 37°C. After the thermostatic valve is fully closed, the oil that returns to the oil pan through the oil return channel will not enter the oil dipstick tube, and there will be a height difference between the dipstick tube and the oil in the oil pan. At this time, it is relatively accurate to read the oil level scale of the oil dipstick directly without starting the engine. There will only be a little error due to different oil temperatures leading to different oil densities, but it also avoids the larger error caused by different oil return volumes due to different downtimes.

[0119] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the oil level measurement method of the present application. More simple transformations based on this technical concept are all within the protection scope of the present application.
