[0042] Figure 1 A vehicle oil circuit detection method is provided as an exemplary embodiment of the present application, and the detection method includes:

[0043] S11. Obtain the impurity content in the fuel tank of the vehicle, and determine that the ratio of the impurity content to the volume of the fuel tank is a first ratio.

[0044] The impurities in the fuel tank of the vehicle may be impurities on the side wall of the fuel tank, or impurities at the bottom of the fuel tank, such as sediment at the bottom of the fuel tank. The impurities may be carbon deposits, particulate matter, oxidation products, chemical pollutants, etc. in the fuel tank.

[0045] The impurity content can be expressed as the height of the impurities, the mass of the impurities, or the volume of the impurities. The impurity content can be detected by a detection device installed on the oil line. The detection device can be an optical device or an acoustic device. For example, the detection device is an ultrasonic sensor installed on the oil tank. By measuring the time of the echo to calculate the distance, the spatial changes on the liquid surface of the oil tank are detected, and the height of the impurities is indirectly estimated. Or the detection device is an infrared sensor, which uses the ability of infrared rays to penetrate liquids and judges the presence and content of impurities based on the absorption of infrared rays.

[0046] When the impurity content is expressed as impurity volume, after obtaining the impurity content, the ratio of the impurity volume to the volume of the fuel tank can be determined to determine the proportion of impurities in the fuel tank, which is helpful for subsequent judgment of whether the oil circuit is blocked.

[0047] When the impurity content is expressed as impurity height, the impurity height can be obtained, and then the ratio of the impurity height to the fuel tank height can be determined to determine the proportion of the impurity height in the fuel tank, which is conducive to the subsequent judgment of whether the oil circuit is blocked.

[0048] When the impurity content is expressed as impurity mass, the mass and density of the impurities can be obtained, the volume of the impurities can be determined by the density and mass of the impurities, and then the ratio of the impurity volume to the volume of the fuel tank can be determined to determine the proportion of impurities in the fuel tank. The density of the impurities can be the average of the densities of multiple impurities in the fuel tank.

[0049] Fuel is sprayed out from the fuel tank, transported through the oil circuit, and finally sprayed into the engine's intake duct or directly into the cylinder. After mixing with air, it burns in the engine to generate power. Therefore, by detecting the impurity content in the fuel tank, the blockage of the oil circuit can be discovered in time, thereby timely discovering solid particles, sludge and sediment that may cause blockage of the engine or oil circuit system, thereby preventing equipment failure or damage.

[0050] S12. Determine the expected flow rate of vehicles.

[0051] The expected flow rate indicates the amount of oil that flows through the oil circuit of the current vehicle within a preset time period when the oil circuit of the vehicle is not blocked. It can be understood that the expected flow rate can also indicate the amount of oil that needs to flow through the oil circuit of the vehicle within a preset time period in theory to achieve the current expected driving target of the vehicle when the oil circuit is not blocked. The expected driving target can be starting the vehicle from a parked state; or accelerating the vehicle to a preset position during driving; or climbing a slope during driving.

[0052] Different expected driving targets require different expected flow rates, and the expected flow rates can be calculated based on different expected driving targets.

[0053] In one embodiment, in order to accurately obtain the expected flow rate, the current driving force requirement of the vehicle may be determined by the expected driving target to determine the current expected flow rate of the vehicle.

[0054] Then determine the expected flow of vehicles, including:

[0055] Obtaining a driving force requirement of the vehicle; wherein the driving force requirement indicates the power required to drive the vehicle to achieve the vehicle's current desired driving target;

[0056] Determine the expected flow rate within a preset time period based on driving force requirements.

[0057] Corresponding to the desired driving target, the driving force demand may be the power required to start the vehicle from a parked state; or it may be the power required to accelerate the vehicle to a preset position during driving; or it may be the power required to climb a hill during driving.

[0058] When the vehicle's expected driving target is different, the required power is also different. Therefore, the expected flow rate that the vehicle's oil circuit needs to flow through within a preset time period to achieve the expected driving target can be calculated by different driving force requirements, and the accuracy of the expected flow rate calculation can be improved. Therefore, the expected flow rate can be compared with the actual amount of oil flowing through the oil circuit, which is conducive to the subsequent judgment of whether the oil circuit is blocked.

[0059] S13, determining the actual flow rate, and determining the ratio of the actual flow rate to the expected flow rate as a second ratio.

[0060] The actual flow rate indicates the amount of oil flowing through the oil circuit within a preset time period, and the actual flow rate can be measured by a liquid flow metering device located at a preset position of the oil circuit. The preset position is, for example, the end of the oil circuit, or a position close to the end of the oil circuit. It can be understood that the actual flow rate can also indicate the amount of oil actually flowing through the oil circuit of the vehicle measured within a preset time period when the oil is sprayed into the oil circuit with the expected flow rate as the oil supply target.

[0061] Specifically, a fuel tank is provided on the fuel line of the vehicle, and the fuel tank sprays fuel into the fuel line according to the desired flow rate to deliver fuel to the engine through the fuel line. The fuel is sprayed into the intake duct of the engine or directly into the cylinder, mixed with air and burned in the engine to generate power to drive the vehicle.

[0062] When the oil circuit is not blocked, the amount of oil flowing through the oil circuit within the preset time is the expected flow rate. When the oil circuit is blocked, the fuel tank cannot spray oil according to the expected flow rate, resulting in a decrease in the amount of oil entering the oil circuit, and the amount of oil flowing through the oil circuit within the preset time will also decrease. Therefore, the expected flow rate flowing through the oil circuit can be calculated, and then the actual flow rate flowing through the oil circuit within the preset time can be measured, and then the actual flow rate can be compared with the expected flow rate to determine the ratio of the actual flow rate to the expected flow rate, and the reduction of the actual flow rate relative to the expected flow rate can be obtained. For example, if the second ratio is 80%, it can be known that the actual flow rate has decreased by 20% relative to the expected flow rate, and thus whether the oil circuit is blocked can be judged based on the reduction of the actual flow rate relative to the expected flow rate.

[0063] S14. Determine the blockage coefficient of the oil circuit based on the first ratio and the second ratio and their corresponding preset weight coefficients.

[0064] The congestion coefficient is determined by weighting the first ratio and the second ratio.

[0065] The blockage coefficient is determined by weighting the first ratio and the second ratio, and the weight coefficients of the first ratio and the second ratio can be the same. For example, both are 1, indicating that the blockage coefficient is calculated under the same influence. Alternatively, in order to improve the accuracy of detecting oil circuit blockage, the first ratio and the second ratio can be weighted and calculated based on the preset first weight coefficient and the second weight coefficient according to the influence of the impurities in the fuel tank and the actual flow rate on the oil circuit blockage, and an accurate blockage coefficient can be obtained, so that it can be accurately judged whether the oil circuit is blocked.

[0066] In one embodiment, the blockage coefficient of the oil circuit is determined based on the first ratio and the second ratio and their corresponding preset weight coefficients, including:

[0067] Based on a preset first weight coefficient and a preset second weight coefficient, a weighted calculation is performed on the first ratio and the second ratio to obtain a congestion coefficient.

[0068] The first weight coefficient and the second weight coefficient are preset values ​​and can be set based on experience. For example, the first weight coefficient is 0.2 and 0.3, and the second weight coefficient is 0.7 and 0.8.

[0069] The ratio of impurity content to tank volume is the first ratio α, the ratio of actual flow to expected flow is the second ratio β, the preset first weight coefficient is 0.2, and the second weight coefficient is 0.8. The calculation formula of the blockage coefficient a can be: a=0.2*α+0.8*(1-β).

[0070] S15. Determine whether the oil circuit is blocked based on the blockage coefficient.

[0071] The blockage coefficient can accurately determine whether the oil circuit is blocked based on the influence of oil tank impurities and actual flow rate on the oil circuit blockage, so as to detect the blockage of the oil circuit in time and reduce the risk of oil circuit obstruction.

[0072] In one embodiment, determining whether the oil circuit is blocked based on the blockage coefficient includes:

[0073] In response to the blockage coefficient being not less than a preset first threshold, it is determined that the blockage type of the oil circuit is blockage.

[0074] The first threshold is set according to actual conditions, for example, 0.2 or 0.3.

[0075] The ratio of the impurity content to the tank volume is a first ratio α, and the ratio of the actual flow rate to the expected flow rate is a second ratio β. The blockage coefficient a can be calculated according to the preset weight coefficient and the calculation formula of the blockage coefficient, a=0.2*α+0.8*(1-β). When a is not less than the first threshold, for example, a≥0.2, it can be determined that the impurity content in the tank is high, and the amount of oil flowing through the oil circuit is reduced significantly. At this time, it can be determined that the blockage type of the oil circuit is blockage.

[0076] In one embodiment, in response to the blockage coefficient being less than a preset second threshold, the blockage type of the oil circuit is determined to be non-blocked.

[0077] The first threshold is greater than the second threshold.

[0078] The first threshold and the second threshold are preset values. For example, the first threshold may be 0.2 or 0.3, and the second threshold may be 0.1 or 0.2.

[0079] When the blockage coefficient a is less than the second threshold, for example, a is less than 0.1, it can be determined that the impurity content in the oil tank is small and the amount of oil flowing through the oil circuit is reduced slightly. At this time, it can be determined that the oil circuit is not blocked and can operate normally.

[0080] In one embodiment, in order to formulate different solutions according to different blockage degrees and solve the problem of oil circuit blockage in a targeted manner, the blockage degree can be characterized by grading the blockage degree. When the blockage coefficient is between the second threshold and the first threshold, it can be determined that the blockage type of the oil circuit is slight blockage.

[0081] The first threshold is greater than the second threshold.

[0082] The first threshold and the second threshold are preset values. For example, the first threshold may be 0.2 or 0.3, and the second threshold may be 0.1 or 0.2.

[0083] When the blockage coefficient a is between the second threshold and the first threshold, for example, 0.1≤a<0.2, it can be determined that there are impurities in the oil tank, but it has not reached the level of blockage, and the amount of oil flowing through the oil circuit has decreased, but it has not reached the level of blockage. At this time, it can be determined that the oil circuit is slightly blocked and has not affected the normal operation of the oil circuit for the time being, but it may affect the normal operation of the oil circuit later.

[0084] In order to improve the performance and service life of the vehicle, when it is determined that the oil circuit is blocked, it can be judged whether it is necessary to prompt the user to clean the fuel tank according to the different degrees of blockage in the oil circuit, and further determine when to clean the oil circuit to achieve the effect of cleaning the oil circuit without damaging the vehicle performance.

[0085] When the blockage type is not blocked, the oil circuit does not need to be cleaned and the user does not need to be prompted. When the blockage type is slightly blocked, the user can be prompted to check the oil circuit. The user can judge whether the oil circuit needs to be cleaned based on the inspection situation to avoid the problem of frequent cleaning of the oil circuit causing a decrease in the working efficiency of the exhaust system.

[0086] When the blockage type is blockage, the user can be prompted to clean the oil circuit to remove impurities or oil stains in the oil circuit, avoiding the problem of oil circuit blockage and poor or even no fuel injection caused by not cleaning the oil circuit for a long time, reducing the problems of poor acceleration and difficulty in starting after shutdown caused by poor oil circuit, and reducing damage to the engine.

[0087] When the blockage type is determined to be unblocked, the oil circuit may not be cleaned and the user may not be prompted, thereby reducing information overload for the user and maintaining a simple user interface and a smooth user experience.

[0088] When the blockage type is determined to be a slight blockage, the user can be prompted to check the oil circuit. At this time, the blockage degree of the oil circuit will not temporarily affect the normal operation of the oil circuit, so the user can choose to view the detailed blockage of the oil circuit according to the prompt content, and then decide whether to clean it. Or do not check the blockage of the oil circuit, and clean the oil circuit when the blockage type of the oil circuit is determined to be a blockage. Avoid the problem of the three-way catalytic converter in the vehicle's exhaust system being reduced in efficiency due to frequent cleaning of the oil circuit by the user, thereby avoiding the problem of poor exhaust of the car, increased engine back pressure, affecting the engine's intake efficiency and power output, and causing power reduction, which can improve the performance and service life of the vehicle.

[0089] When the blockage type is determined to be a blockage, the user can be prompted to clean the oil circuit to ensure that impurities or oil stains in the oil circuit can be removed after cleaning, ensuring that the fuel reaches the engine smoothly and unimpeded, thereby improving the fuel utilization efficiency and enabling the engine to obtain a more sufficient fuel supply, thereby improving the vehicle's power performance and acceleration response.
