The following describes in detail a method and an apparatus for calculating the service life of engine oil of a vehicle, a readable medium and an electronic device according to the present application with reference to specific embodiments.
Referring to fig. 1, fig. 1 schematically illustrates a flow of steps of a method for calculating a service life of engine oil of a vehicle according to an embodiment of the present application. The main execution body of the vehicle oil life calculation method may be a controller, and may mainly include steps S101 to S104 as follows.
Step S101, an engine speed and an engine operation time integrated value of the vehicle are acquired.
The cumulative value of the engine running time refers to the cumulative running time of the engine recorded in the memory. The engine running time accumulated value is corrected by the calculated engine running time accumulated value so as to obtain a more accurate engine running time accumulated value, thereby being beneficial to obtaining a more accurate engine oil life through calculating the engine running time accumulated value. Therefore, errors between the calculated value of the engine oil life and the actual value of the engine oil life are reduced, so that a user can grasp the more accurate engine oil life in real time, and when the residual engine oil life reaches a preset life value, the engine oil can be replaced in time.
Step S102, determining an engine operation time accumulated value according to the engine speed.
Determining whether the engine is in a starting state according to the engine rotating speed, and considering that the engine is in an un-starting state when the engine rotating speed is less than or equal to a preset threshold value; and when the engine speed is greater than a preset threshold, the engine is considered to be in a starting state. When the engine is in a started or non-started state, different accumulated values of engine running time are respectively corresponding. Therefore, the starting state of the engine is judged through the engine speed, and the corresponding engine running time accumulated value is further determined according to the starting state of the engine, so that the more accurate engine running time accumulated value is obtained.
Step S103, accumulating the engine operation time accumulated value and the engine operation time accumulated value to obtain an updated engine operation time accumulated value.
After the engine running time accumulated value is obtained, the engine running time accumulated value and the engine running time accumulated value are accumulated to obtain an updated engine running time accumulated value. And correcting the total engine operation time through the calculated engine operation time accumulated value, so that the engine operation time consistent with the actual working condition can be obtained, and the errors of the residual engine oil life and the actual engine oil life are reduced.
Step S104, calculating to obtain the residual engine oil life of the vehicle according to the updated running time accumulated value of the engine and the total life time corresponding to the engine oil of the vehicle.
The more accurate updated running time accumulated value of the engine is obtained, so that the more accurate residual engine oil life is calculated.
In the technical scheme provided by the embodiment of the application, the starting state of the engine is determined according to the rotating speed of the engine, the corresponding engine running time accumulated value is obtained according to the starting state of the engine, and then the engine running time accumulated value and the engine running time accumulated value are accumulated, so that a more accurate running mileage accumulated value is obtained. And finally, calculating to obtain the residual engine oil life through the updated running time accumulated value of the engine and the total life time corresponding to the engine oil of the vehicle. Compared with the scheme that the engine operation time reaches the preset time limit to determine the service life of the engine oil, the method combines the influence of the real-time working condition on the service life of the engine oil, corrects the total engine operation time by calculating the accumulated value of the engine operation time, improves the accuracy when the residual service life of the engine oil is calculated, reduces the error of the service life of the engine oil with the actual service life of the engine oil, and enables the calculated service life of the engine oil to be closer to the actual service life of the engine oil. In addition, the more accurate residual engine oil life is obtained through calculation, so that whether the maintenance period is reached or not can be determined in time, the engine oil can be replaced in time, and the condition that the engine oil is influenced due to the fact that the physical performance of the engine oil is reduced is avoided.
In one embodiment of the present application, determining an engine run time accumulated value based on engine speed includes:
if the engine speed is greater than a preset threshold, determining correction coefficients corresponding to all the running state parameters according to the running state parameters of the vehicle;
and calculating an engine operation time accumulated value according to the correction coefficient.
The preset threshold may be set according to actual needs, for example, the preset threshold may be set to 500 revolutions, and if the rotational speed of the engine is greater than 500 revolutions, the engine is considered to be in a normal working state. When the engine is in a normal working state, the current working condition can also have a certain influence on the service life of the engine oil, so that the influence of the current working condition on the service life of the engine oil needs to be considered in order to obtain a more accurate service life of the engine oil. Specifically, the correction coefficients corresponding to the running state parameters of the vehicle are determined according to the running state parameters of the vehicle, and then the engine running time accumulated value is calculated according to the correction coefficients, so that a more accurate engine running time accumulated value is obtained.
Therefore, when the engine is in an un-started state or in a started state, the engine is respectively corresponding to different correction coefficients, so that the accumulated value of the engine running time corresponding to the current working condition is determined, and the calculation of the subsequent residual engine oil life is facilitated.
In one embodiment of the present application, determining correction coefficients corresponding to each operating state parameter according to the operating state parameter of the vehicle includes:
acquiring a control curve graph of the engine, wherein the control curve graph comprises a plurality of different working condition areas, and the different working condition areas correspond to different correction coefficients;
if the running state parameters of the vehicle comprise the engine speed and the load, searching a corresponding first working condition area in the control curve graph according to the engine speed and the load to obtain a first correction coefficient;
if the running state parameters of the vehicle comprise the current environment temperature, searching a corresponding second working condition area in the control curve graph according to the current environment temperature to obtain a second correction coefficient;
if the running state parameters of the vehicle comprise the water temperature of the engine, searching a corresponding third working condition area in the control curve graph according to the water temperature of the engine to obtain a third correction coefficient.
And when the engine rotating speed is greater than a preset threshold value, the engine is considered to be in a normal running state. When the engine is in a normal running state, the engine speed, load, ambient temperature and engine water temperature all have certain influence on the service life of the engine oil, but when the engine is in different speeds, loads, ambient temperatures and engine water temperatures, the influence on the decay speed of the service life of the engine oil is different. Specifically, when the ambient temperature is low and the water temperature is low, the vehicle is in a cold-hot state in which the decay of the engine oil life is also different from that in a warm-up state. Thus, the engine operation time accumulated value is corrected by the engine speed, load, ambient temperature and engine water temperature, namely, factors affecting the service life of engine oil are taken into consideration, so that the engine operation time accumulated value consistent with the actual situation is obtained.
Therefore, the engine running time can be more accurately obtained according to different driving conditions of a user by carrying out different corrections on the engine running time by combining the vehicle speed, the engine rotation, the engine load, the ambient temperature and the engine water temperature.
In one embodiment of the present application, calculating an engine run time accumulated value from a correction factor includes:
and multiplying the correction coefficient corresponding to each running state parameter with a preset unit time, then accumulating, and taking the accumulated result as an accumulated value of the running time of the engine.
When the rotation speed of the engine is greater than a preset threshold value N, the engine is considered to be in a normal running state, at the moment, the unit time is considered to be t not equal to 0, and after the unit time is multiplied by coefficients K1, K2 and K3 respectively, an engine running time accumulated value M is obtained through calculation. Wherein K1 is a correction value obtained by checking map1 according to the engine speed and load, K2 is a correction value obtained by checking map2 according to the ambient temperature, and K3 is a correction value obtained by checking map3 according to the engine water temperature.
In this way, the accumulated value of the engine running time is obtained by multiplying the first correction coefficient, the second correction coefficient and the third correction coefficient by the preset unit time respectively and accumulating the multiplication results.
In one embodiment of the present application, determining an engine run time accumulated value from engine speed further comprises:
and if the engine speed is less than or equal to the preset threshold value, determining the engine operation time accumulated value as a set value.
Also taking 500 revolutions as an example of the preset threshold, when the engine speed is less than or equal to 500 revolutions, the engine is considered to be in an un-started state. Determining an engine running time accumulated value as a set value when the engine is in an inactive state; thus, even if the vehicle does not operate the engine for a long period of time, the engine operation time life is not accumulated at this time, so that the maintenance period of the vehicle can be prolonged to some extent.
In one embodiment of the present application, accumulating the engine running time accumulated value with the engine running time accumulated value to obtain an updated engine running time accumulated value, including:
after the vehicle is powered on, judging whether to reset a memory for storing running time accumulated values;
and if the memory is reset, resetting the accumulated value of the engine running time stored in the memory to zero, and taking the accumulated value of the engine running time as the updated accumulated value of the engine running time.
Thus, by resetting the memory, the engine running time integrated value is initialized to zero, so that interference of other factors on calculation of the engine running time integrated value is reduced.
In one embodiment of the present application, the accumulating engine running time accumulated value and the engine running time accumulated value are accumulated to obtain an updated engine running time accumulated value, and the method further includes:
if the memory is not reset, acquiring an engine running time accumulated value stored in the memory;
and accumulating the engine running time accumulated value and the engine running time accumulated value to obtain an updated engine running time accumulated value.
In this way, when the memory is not reset, the accumulated value of the engine running time is obtained, and the accumulated value of the engine running time are accumulated to obtain the updated accumulated value of the engine running time, so that the accumulated value of the total engine running time is obtained, and the calculation of the service life of the subsequent engine oil is facilitated.
In some embodiments of the present application, based on the above technical solutions, according to the updated running time cumulative value of the engine and the total service life time corresponding to the vehicle oil, the remaining oil life of the vehicle is calculated, and when the remaining oil life is calculated, the formula is satisfied: residual engine oil life= [1- (updated engine operating time integrated value/total life time) ]x100%.
Therefore, the residual engine oil life can be calculated through the calculation formula which meets the residual engine oil life, and further a user can grasp the more accurate engine oil life, so that whether the maintenance period is reached or not is determined, and the engine oil can be replaced in time.
In one embodiment of the present application, referring to fig. 2, fig. 2 schematically illustrates a flow of steps of a method for calculating a service life of engine oil of a vehicle according to another embodiment of the present application. The method comprises the following steps:
in step S201, the engine speed of the vehicle is acquired.
The engine running time accumulated value is corrected by the calculated engine running time accumulated value so as to obtain a more accurate engine running time accumulated value, thereby being beneficial to obtaining a more accurate engine oil life through calculating the engine running time accumulated value. Therefore, errors between the calculated value of the engine oil life and the actual value of the engine oil life are reduced, so that a user can grasp the more accurate engine oil life in real time, and when the residual engine oil life reaches a preset life value, the engine oil can be replaced in time.
Step S202, judging whether the engine speed is greater than a preset threshold value, and determining a corresponding correction coefficient.
And when the engine speed is greater than a preset threshold, determining a correction coefficient corresponding to each running state parameter according to the running state parameter of the vehicle. Specifically, if the running state parameters of the vehicle include the engine speed and the load, searching a corresponding first working condition area map1 in a control graph according to the engine speed and the load to obtain a first correction coefficient K1; if the running state parameters of the vehicle comprise the current environment temperature, searching a corresponding second working condition area map2 in the control curve graph according to the current environment temperature to obtain a second correction coefficient K2; if the running state parameters of the vehicle comprise the water temperature of the engine, searching a corresponding third working condition area map3 in the control graph according to the water temperature of the engine to obtain a third correction coefficient K3.
And when the engine rotating speed is greater than a preset threshold value, the engine is considered to be in a normal working state. When the engine is in a normal running state, the engine speed, load, ambient temperature and engine water temperature all have certain influence on the service life of the engine oil, but when the engine is in different speeds, loads, ambient temperatures and engine water temperatures, the influence on the decay speed of the service life of the engine oil is different. Specifically, when the ambient temperature is low and the water temperature is low, the vehicle is in a cold-hot state in which the decay of the engine oil life is also different from that in a warm-up state. Thus, the engine operation time accumulated value is corrected by the engine speed, load, ambient temperature and engine water temperature, namely, factors affecting the service life of engine oil are taken into consideration, so that the engine operation time accumulated value consistent with the actual situation is obtained.
When the engine speed is less than or equal to the preset threshold, the engine is considered to be in an un-started state. Determining an engine running time accumulated value as a set value when the engine is in an inactive state; thus, even if the vehicle does not operate the engine for a long period of time, the engine operation time life is not accumulated at this time, so that the maintenance period of the vehicle can be prolonged to some extent.
Step S203, calculating an engine operation time accumulated value according to the correction coefficient.
When the rotation speed of the engine is greater than a preset threshold value N, the engine is considered to be in a normal running state, at the moment, the unit time is considered to be t not equal to 0, and after the unit time is multiplied by coefficients K1, K2 and K3 respectively, an engine running time accumulated value M is obtained through calculation. Wherein K1 is a correction value obtained by checking map1 according to the engine speed and load, K2 is a correction value obtained by checking map2 according to the ambient temperature, and K3 is a correction value obtained by checking map3 according to the engine water temperature.
In this way, the accumulated value of the engine running time is obtained by multiplying the first correction coefficient, the second correction coefficient and the third correction coefficient by the preset unit time respectively and accumulating the multiplication results.
When the engine rotating speed is less than or equal to a preset threshold value, the engine is in an un-started state, and the correction coefficient is determined to be a set value; thus, even if the vehicle does not operate the engine for a long period of time, the engine operation time life is not accumulated at this time, so that the maintenance period of the vehicle can be prolonged to some extent.
Step S204, after the vehicle is powered on, it is determined whether to perform a reset operation on the memory for storing the running time integrated value.
In step S205, if the memory is reset, the accumulated value of the engine operation time stored in the memory is zeroed, and the accumulated value of the engine operation time is used as the updated accumulated value of the engine operation time.
In step S206, if the memory is not reset, the accumulated value of the engine running time stored in the memory is obtained.
Step S207, accumulating the engine operation time accumulated value and the engine operation time accumulated value to obtain an updated engine operation time accumulated value, and storing the updated engine operation time accumulated value into a memory.
