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

[0043] S11, the impurity content in the oil tank of the vehicle is obtained, and the ratio of the impurity content to the volume of the oil tank is determined as a first ratio.

[0044] The impurities in the oil tank of the vehicle can be the impurities on the side wall of the oil tank, or the impurities at the bottom of the oil tank, such as the precipitates at the bottom of the oil tank. The impurities can be carbon deposition, particulate matter, oxidation products, chemical contaminants, etc. in the oil tank.

[0045] The impurity content can be expressed as the height of the impurities, or as the mass of the impurities, or as the volume of the impurities. The impurity content can be detected by a detection device installed on the oil circuit, which can be an optical device or an acoustic device. For example, the detection device is an ultrasonic sensor arranged on the oil tank, which calculates the distance by measuring the time of the echo to detect the spatial change of the oil surface, and then indirectly estimates the height of the impurities. Or the detection device is an infrared sensor, which uses the ability of infrared light to penetrate liquid to judge the existence and content of impurities according to the absorption of infrared light.

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

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

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

[0049] Fuel is sprayed from the fuel tank, transported through the oil way, and finally sprayed into the intake port of the engine or directly sprayed into the cylinder. After mixing with air, it is burned in the engine to generate power. Therefore, by detecting the impurity content in the fuel tank, the blockage of the oil way can be found in time, so as to find the solid particles, oil sludge and precipitates that may cause the engine or oil way system to be blocked in time, thereby preventing equipment failure or damage.

[0050] S12, determine the expected flow of the vehicle.

[0051] The expected flow indicates the amount of oil flowing through the oil way of the vehicle within a preset time period under the condition that the oil way is not blocked. It can be understood that the expected flow can also indicate the amount of oil flowing through the oil way of the vehicle within a preset time period under the condition that the oil way is not blocked, theoretically, to complete the expected driving target of the vehicle at present. The expected driving target can be that the vehicle starts from a parked state; or can be that the vehicle accelerates to a preset position during driving; or can be that the vehicle completes hill climbing during driving.

[0052] The expected flow required by different expected driving targets is different, and the expected flow can be calculated according to different expected driving targets.

[0053] In one embodiment, in order to accurately obtain the expected flow, the driving power demand of the vehicle at present can be determined through the expected driving target to determine the expected flow of the vehicle at present.

[0054] The expected flow of the vehicle is determined, including:

[0055] Obtain the driving power demand of the vehicle; wherein the driving power demand indicates the power required to drive the vehicle to complete the expected driving target of the vehicle at present;

[0056] According to the driving power demand, determine the expected flow within a preset time period.

[0057] Corresponding to the expected driving target, the driving power demand can be the power required for the vehicle to start from a parked state; or can be the power required for the vehicle to accelerate to a preset position during driving; or can be the power required for the vehicle to complete hill climbing during driving.

[0058] When the expected driving target of the vehicle is different, the required power is also different, so the expected flow required by the oil way of the vehicle within a preset time period under the condition that the oil way is not blocked, theoretically, to complete the expected driving target, can be calculated through different driving power demands, which can improve the accuracy of the expected flow calculation. Therefore, the expected flow and the actual amount of oil flowing through the oil way can be compared, which is beneficial to subsequent judgment of whether the oil way is blocked.

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

[0060] The actual flow rate indicates the amount of oil flowing through the oil circuit in a preset time period, which can be measured by a liquid flow metering device arranged at a preset position of the oil circuit. The preset position may, for example, be the end of the oil circuit or a position close to the end of the oil circuit. Understandably, the actual flow rate can also indicate the amount of oil measured in the preset time period flowing through the oil circuit of the vehicle when the oil is sprayed into the oil circuit at the expected flow rate.

[0061] Specifically, an oil tank is arranged on the oil circuit of the vehicle, and the oil tank sprays oil into the oil circuit according to the expected flow rate to deliver fuel to the engine through the oil circuit. The fuel is sprayed into the intake port 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 in the preset time period is the expected flow rate. When the oil circuit is blocked, the oil tank cannot spray oil according to the expected flow rate, resulting in a decrease in the amount of oil entering the oil circuit, and a decrease in the amount of oil flowing through the oil circuit in the preset time period. Therefore, by calculating the expected flow rate flowing through the oil circuit, measuring the actual flow rate flowing through the oil circuit in the preset time period, and comparing the actual flow rate with the expected flow rate, the ratio of the actual flow rate to the expected flow rate can be determined, and the decrease in the actual flow rate relative to the expected flow rate can be obtained, for example, the second proportion is 80%, which indicates that the actual flow rate is reduced by 20% relative to the expected flow rate, so that the decrease in the actual flow rate relative to the expected flow rate is determined to determine whether the oil circuit is blocked.

[0063] S14, determining a blockage coefficient of the oil circuit based on the first proportion and the second proportion and their respective preset weight coefficients.

[0064] The blockage coefficient is determined by weighting the first proportion and the second proportion.

[0065] The blockage coefficient is determined by weighting the first proportion and the second proportion, and the weight coefficients of the first proportion and the second proportion 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 the blockage of the oil circuit, the first proportion and the second proportion 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 oil tank and the actual flow rate on the blockage of the oil circuit, so as to obtain an accurate blockage coefficient, thereby accurately determining whether the oil circuit is blocked.

[0066] Therefore, in one embodiment, the blockage coefficient of the oil circuit is determined based on the first proportion and the second proportion and their respective preset weight coefficients, comprising:

[0067] The first proportion and the second proportion are weighted and calculated based on the preset first weight coefficient and the preset second weight coefficient, to obtain a blockage coefficient.

[0068] The first weight coefficient and the second weight coefficient are preset values, which can be set according to experience. For example, the first weight coefficient is 0.2 or 0.3, and the second weight coefficient is 0.7 or 0.8.

[0069] The ratio of the impurity content to the oil tank volume is the first proportion α, and the ratio of the actual flow to the expected flow is the second proportion 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, determining whether the oil circuit is blocked based on the blockage coefficient.

[0071] The blockage coefficient can accurately determine whether the oil circuit is blocked according to the influence of the oil tank impurity and the actual flow on the oil circuit blockage, so as to timely detect the blockage of the oil circuit and reduce the risk of poor oil circuit.

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

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

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

[0075] The ratio of the impurity content to the oil tank volume is the first proportion α, and the ratio of the actual flow to the expected flow is the second proportion 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 oil tank is relatively high, and the amount of oil flowing through the oil circuit is reduced. 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 as unblocked.

[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 can be 0.2 or 0.3, and the second threshold can be 0.1 or 0.2.

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

[0080] In one embodiment, in order to formulate different solutions according to different blockage degrees, and solve the problem of oil circuit blockage targetedly, the blockage degree can be graded to represent the blockage degree. When the blockage coefficient is between the second threshold value and the first threshold value, it can be determined that the blockage type of the oil circuit is slight blockage.

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

[0082] The first threshold value and the second threshold value are preset values, for example, the first threshold value can be 0.2, 0.3, and the second threshold value can be 0.1, 0.2.

[0083] When the blockage coefficient a is between the second threshold value and the first threshold value, for example, 0.1≤a<0.2, it can be determined that there is impurity in the oil tank, but it does not reach the degree of blockage, and the amount of oil flowing through the oil circuit is reduced, but it does not reach the degree of blockage. At this time, it can be determined that the oil circuit is slightly blocked, and it does not affect the normal work of the oil circuit for the time being, but it may affect the normal work of the oil circuit later.

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

[0085] When the blockage type is not blocked, the oil circuit can not be cleaned, and the user can not be prompted. When the blockage type is slight blockage, the user can be prompted to check the oil circuit, and the user can determine whether the oil circuit needs to be cleaned according to the checking situation, so as to avoid the problem of reducing the working efficiency of the exhaust system caused by frequent cleaning of the oil circuit.

[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, which avoids the problem of poor oil injection or even no oil injection caused by long-term blockage of the oil circuit, reduces the problems of weak acceleration and difficult starting after stalling caused by poor oil circuit, and reduces the damage to the engine.

[0087] When it is determined that the blockage type is not blocked, the oil circuit can not be cleaned, and the user can not be prompted, which reduces the information overload of the user and maintains the simplicity of the user interface and the smoothness of the user experience.

[0088] When the blockage type is determined to be slight blockage, the user can be prompted to check the oil circuit. At this time, the degree of blockage of the oil circuit does 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 without viewing the blockage of the oil circuit, wait until the blockage type of the oil circuit is determined to be blockage to clean the oil circuit. Avoid the problem of frequent cleaning of the oil circuit by the user, which leads to the decrease of the working efficiency of the three-way catalyst in the exhaust system of the vehicle, thereby avoiding the problem of poor exhaust of the automobile, increase of the engine back pressure, influence of the engine intake efficiency and power output, and decrease of the power, which can improve the performance and service life of the vehicle.

[0089] When the blockage type is determined to be blockage, the user can be prompted to clean the oil circuit, to ensure that the impurities or oil stains in the oil circuit can be removed after cleaning, to ensure that the fuel reaches the engine smoothly and unobstructed, to improve the use efficiency of the fuel, and to make the engine obtain more sufficient fuel supply, thereby improving the power performance and acceleration response of the vehicle.
