It should be noted that the device for storing and checking the driving range of the vehicle provided by the above embodiment and the method for storing and checking the driving range of the vehicle provided by the above embodiment belong to the same concept, wherein the specific manner of executing the operation by each module and unit has been described in detail in the method embodiment, and is not described herein again. In practical applications, the road condition refreshing apparatus provided in the above embodiment may distribute the above functions by different functional modules according to requirements, that is, divide the internal structure of the apparatus into different functional modules to complete all or part of the above described functions, which is not limited herein.
Referring to fig. 3, the process of acquiring the total mileage in practical situations is as follows:
when the received bus speed signal of the whole vehicle is effective, the vehicle speed value in the bus original vehicle speed signal before vehicle speed conversion is directly accumulated to obtain a vehicle speed accumulated value.
And when the sum of the vehicle speed accumulated value and the initial increment value is greater than or equal to a preset accumulated threshold value, clearing the vehicle speed accumulated value and updating the total running mileage and the initial increment value, wherein the updated total running mileage is equal to the sum of the total running mileage before updating and the mileage increment value mapped on the accumulated threshold value. And the updated initial increment value is equal to the difference between the vehicle speed accumulated value and the accumulated threshold value.
The accumulation threshold is obtained by presetting according to an accumulation period and the vehicle speed precision, and the sending period of the bus original vehicle speed signal is the acquisition period of the vehicle speed value. For example, when the transmission period of the bus original speed signal is 10ms, the period for acquiring the speed value is 10ms, and the speed accumulated value is accumulated once every 10 ms. The mileage increment is equal to the product of the accumulation threshold, the period and the preset vehicle speed precision. The accumulation threshold, the vehicle speed precision or the mileage increment can be preset according to actual requirements. For example, if the transmission period of the original bus speed signal is 10ms, the period of the acquired vehicle speed value is 10ms, the vehicle speed accumulated value is accumulated once every 10ms, the vehicle speed precision is 0.05625km/h, and when the mileage increment is preset to be 0.1km, the corresponding accumulated threshold value is 640000, that is, the vehicle speed value is accumulated every full 640000, which means that the current total driving mileage is increased by 0.1km. And in the continuous driving period of the vehicle, the mileage value of the total driving mileage increased is the subtotal mileage. And (3) carrying out remainder on the vehicle speed accumulated value by using an accumulated threshold 640000, wherein a remainder result is an increment initial value when the vehicle speed value is accumulated next time. When the vehicle speed value is accumulated next time, the accumulated result is used as an initial value for accumulation, so that the error of the total driving mileage can be reduced. The accumulation threshold value and the sending period of the bus original speed signal can be calibrated according to different items, and the universality is improved. The total driving mileage obtained by the method is high in precision, the total driving mileage is obtained after the speed values are accumulated, the memory module is prevented from being frequently erased and written due to frequent change of the total driving mileage, and the service life of the chip is prolonged.
As shown in fig. 4, after the total driving range is obtained in an actual situation, when the total driving range is every 1km, the total driving range is stored in the storage units of the SoC, such as eMMC, UFS, and the like as K1, K2, and K3, respectively, and the total driving range can be written in a file form, and a check code can be added to prevent data from being tampered with maliciously.
As shown in fig. 5, in reading the mileage data in an actual situation, the stored K1, K2, and K3 are read and processed, respectively, and then the K1, K2, and K3 are compared with each other, respectively. When K1, K2 and K3 are equal to each other, no error occurs, and a common value among K1, K2 and K3 is output. And when two of the K1, the K2 and the K3 are the same and one of the K1, the K2 and the K3 is different, comparing the difference values among the K1, the K2 and the K3, taking all backup data, namely the difference values among the K1, the K2 and the K3 and the rest backup data are smaller than a preset difference threshold value (for example, 5 km), and taking the backup data with the largest value as the total driving mileage. For example, if the difference values among K1, K2 and K3 are less than 5km, and K1 < K2 < K3, then K3 is taken as the total driving range. Meanwhile, if the difference values among all the backup data, namely the difference values among K1, K2 and K3 are all larger than or equal to 5km, an error is output, and the previous total driving range value is kept as the total driving range.
An embodiment of the present application further provides an electronic device, including: one or more processors; and the storage device is used for storing one or more programs, and when the one or more programs are executed by the one or more processors, the electronic equipment is enabled to realize the automobile mileage storage checking method provided in each embodiment.
