Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
The present frequent regeneration diagnostic methods in vehicles detect the number of regenerations at different calibration periods, which are consecutive but do not intersect. And in the same calibration time period, the regeneration times and the calibration time period are required to meet the requirements so as to report the fault. Such diagnostic logic is not timely and continuous and can result in delayed diagnosis or missed reports.
For example, the calibration time period is 20 hours, that is, a frequent regeneration test is performed every 20 hours, and the frequent regeneration needs to satisfy two conditions at the same time: more than three regenerations in the same time period and the failure may need to be reported until the end of the time period. If the regeneration is performed in the time period of 0-20 and in the 3 rd hour, the 10 th hour and the 13 th hour, the frequent regeneration needs to be judged as the frequency regeneration only after the 20 th hour, so that the frequent regeneration is not in time, and the delay diagnosis is caused; for example, regeneration occurs at the 7 th hour, 18 th hour and 22 th hour, but since the 7 th hour and 18 th hour fall within the 0 to 20 th time zone and the 22 th hour falls within the 21 to 40 th time zone, and do not fall within the same time zone, it cannot be determined that frequent regeneration is performed, and thus there is a problem that the frequent regeneration fails to report.
Based on this, embodiment 1 of the present invention provides a method for detecting frequent regeneration of a particle trap, and fig. 1 is a schematic flow chart of the method for detecting frequent regeneration of a particle trap in embodiment 1 of the present invention, as shown in fig. 1, the method for detecting frequent regeneration of a particle trap includes the following steps:
s101: the current regeneration times of the particle catcher and the current regeneration time period corresponding to the current regeneration times are obtained.
S102: a regeneration duration corresponding to a frequent regeneration criterion and a maximum number of regenerations within the regeneration duration are obtained.
In particular, the regeneration duration corresponding to the frequent regeneration criterion and the maximum number of regenerations within said regeneration duration may be obtained by statistical analysis of historical data of the regeneration of the particulate trap.
For example, 20 hours is used as the regeneration duration and 3 times is used as the maximum regeneration number, i.e., if the particulate trap is regenerated 3 times within 20 hours, the particulate trap may be considered to be regenerated frequently.
S103: and obtaining a comparative initial regeneration time period according to the current regeneration times and the maximum regeneration times.
Specifically, the following technical solution may be adopted to obtain the comparative initial regeneration time period according to the current regeneration time and the maximum regeneration time: subtracting the maximum regeneration times from the current regeneration times and adding 1 to obtain comparison initial regeneration times; and obtaining the comparative initial regeneration time period according to the comparative initial regeneration times and the corresponding relation between the regeneration times and the regeneration time period.
Specifically, the starting time and the regeneration frequency of each regeneration can be obtained and stored in the array, so as to obtain the corresponding relation between the regeneration frequency and the regeneration time period; or the end time and the regeneration times of each regeneration can be acquired and stored in the array, and the corresponding relation between the regeneration times and the regeneration time period can be obtained.
Fig. 2 is a schematic diagram of the corresponding relationship between the regeneration times and the regeneration time period. As shown in FIG. 2, 1, 2, 3, 4 \8230 \ 8230:' regeneration times, which are regeneration times, of the first row of the upper array, and the regeneration end time of each regeneration of the second row of the upper array. After the above values are obtained, they are stored in the following set of correspondences.
For example, as shown in fig. 2, when the 3 rd regeneration is the current regeneration, the corresponding comparison starting regeneration is the 1 st regeneration, and the interval duration between the 3 rd regeneration and the 1 st regeneration is 8 hours, which is less than 20 hours, the frequent regeneration is assumed. For another example, when the 4 th regeneration is the current regeneration number, the corresponding comparison starting regeneration number is the 2 nd regeneration, and the interval duration between the 4 th regeneration and the 2 nd regeneration is 23 hours and is greater than 20 hours, the frequent regeneration is not considered.
Specifically, in order to reduce the memory, the number of arrays in the correspondence relationship between the number of regenerations and the regeneration period is the same as the number of maximum regeneration times. For example, if the maximum number of times of reproduction is 3, only three sets of data are retained in the memory, where one set of data includes one number of times of reproduction and the reproduction time corresponding to the number of times of reproduction.
For example, when only three sets of data are retained in the memory, as shown in fig. 2, the 3 rd regeneration is a frequent regeneration, and when the parking regeneration is successful, the data in the left frame is deleted, and the parking regeneration (the 4 th regeneration at 126 th hour) is retained as the 0 th set of data at the leftmost position below; thereafter, 5 regenerations (227 th hour regeneration) are stored as the 1 st group data at the following intermediate position, and thereafter, 6 regenerations (328 th hour regeneration) are stored as the 1 st group data at the following intermediate position, and thereafter, data of the parking regeneration, that is, the 4 th regeneration is deleted, and 7 is stored as the 0 th group data at the following leftmost position.
S104: and obtaining the interval duration according to the current regeneration time period and the comparison initial regeneration time period.
Specifically, the following technical scheme can be adopted for obtaining the interval duration according to the current regeneration time period and the comparison initial regeneration time period: subtracting the end time of the comparative initial regeneration time period from the end time of the current regeneration time period to obtain the interval duration; or subtracting the starting time of the comparative starting regeneration time period from the starting time of the current regeneration time period to obtain the interval duration.
S105: determining that the particulate trap is frequently regenerated when the interval duration is less than the regeneration duration.
That is, on the premise that the maximum regeneration times within the interval duration satisfy the frequent regeneration standard, if the interval duration is less than the regeneration duration specified by the frequent regeneration standard, the frequent regeneration standard is met; if the interval duration is greater than or equal to the regeneration duration specified by the frequent regeneration standard, the frequent regeneration standard is not met. Therefore, the detection of whether the particle trap is frequently regenerated or not is correspondingly executed for each regeneration of the particle trap, the detection omission is avoided, and the problem of the report omission phenomenon existing in the conventional frequent regeneration is solved.
Further, after determining that the particle catcher is frequently regenerated, the method further comprises: and when the vehicle is in a driving state, sending out an indication message for stopping the driving regeneration of the particle catcher. As described above, frequent regeneration is usually caused by a special working condition during driving, and if the working condition is not changed during driving, the frequent regeneration will exist all the time, and at this time, the driving regeneration of the particulate trap can be stopped, so that the particulate trap can be prevented from entering regeneration frequently, and the fuel consumption is prevented from increasing.
Furthermore, after the indication message for stopping the regeneration of the particle trap driving is sent out, the method further comprises the following steps: acquiring accumulated carbon amount of the particle catcher; and when the accumulated carbon amount reaches a preset second threshold value, sending out an indication message of parking regeneration of the particulate trap. This is because the criterion of the parking regeneration accumulated carbon amount is larger than the criterion of the running regeneration accumulated carbon amount. Because stopped the driving regeneration function of particulate trap, the warning instrument lamp is not bright, does not let the customer perception as far as possible, when tired carbon volume reaches the regenerated requirement of parking, gives an instruction to the customer through DPF yellow light scintillation and does the parking and regenerate.
Further, the particle trap frequent regeneration detection further comprises: and after the parking regeneration is successful, clearing the corresponding relation between the regeneration times and the regeneration time period.
