Description

Technical Field

[0002] At present, the vehicle mileage displayed on the vehicle's central control screen is generally calculated by a controller based on the acquired vehicle speed signal. When the vehicle is turned off, the controller will store the calculated vehicle mileage. When the vehicle is turned on, the controller will read the stored vehicle mileage and display it on the vehicle's central control screen. However, if the vehicle speed signal acquired by the controller is abnormal, it will cause an abnormality in the calculation result of the vehicle mileage, which will in turn cause the vehicle mileage displayed on the vehicle's central control screen to be abnormal, affecting the user's perception and experience. Based on this, how to improve the accuracy of vehicle mileage data processing is a technical problem that needs to be solved urgently. Summary of the invention

Specifically, since the communication between the various devices in the vehicle is mainly based on the CAN bus when the vehicle is traveling each time, it is easy to cause data transmission loss or inaccuracy. For example, the controller obtains the vehicle speed data from the vehicle CAN bus. Due to the possibility of abnormal speed signal received from the CAN bus, the accuracy of the single mileage calculated by the controller based on the vehicle speed data obtained from the vehicle CAN bus cannot be guaranteed, and then the accuracy of the total mileage of the vehicle updated based on the obtained single mileage cannot be guaranteed. This application receives the vehicle speed signal in the CAN bus at the same time through multiple controllers, and each controller calculates the single mileage based on the obtained speed signal, and then the main controller selects an optimal single mileage from the single mileage calculated by each controller as the current single mileage, which can ensure that the final single mileage is calculated based on the vehicle speed signal with the highest accuracy. In this way, the accuracy of the current single driving mileage is improved, thereby improving the accuracy of the vehicle's total driving mileage updated based on the current single driving mileage, and further improving the accuracy of vehicle mileage data processing.

In the description of this application, unless otherwise specified, "plurality" means two or more.

[0036] In order to make those skilled in the art better understand the present application, firstly, Figure 1 , the vehicle involved in this application is briefly described using a specific embodiment.

[0037] See also Figure 1 , showing a block diagram of a vehicle in an embodiment of the present application.

[0038] Specifically, Figure 1 The vehicle 100 shown includes a main controller 101 and at least one auxiliary controller 102, wherein the main controller 101 may be an ECU controller of the vehicle, and the auxiliary controller 102 may be a VIU controller of the vehicle. In the present application, the main controller 101 and each auxiliary controller 102 may communicate with each other, and the main controller 101 and each auxiliary controller 102 may obtain a vehicle speed signal from a CAN bus of the vehicle.

[0039] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0040] Reference Figure 2 , shows a flow chart of a vehicle mileage data processing method in an embodiment of the present application, wherein the vehicle may include a main controller and at least one auxiliary controller, and the vehicle mileage data processing method may be executed by a device having a computing and processing function, for example, it may be executed by the main controller, referring to Figure 1 As shown, the vehicle mileage data processing method includes at least steps 210 to 240, which are described in detail as follows:

[0041] In step 210 , in response to the vehicle switching from the current start state to the stop state, the total mileage of the vehicle up to the last time the vehicle switched from the start state to the stop state is obtained.

[0042] In the present application, it should be noted that when the vehicle is ignited, or when the power button of the vehicle is turned on, or when the vehicle is shifted into the forward / reverse gear, the vehicle can be considered to enter the start state; when the vehicle is turned off, or when the power button of the vehicle is turned off, or when the vehicle is shifted into the P gear, the vehicle can be considered to enter the stop state.

[0043] In the present application, when it is detected that the vehicle switches from the current start state to the stop state, the main controller can obtain the total mileage of the vehicle until the last time it switches from the start state to the stop state. Specifically, the total mileage of the vehicle until the last time it switches from the start state to the stop state can be obtained according to the following steps 211 to 213:

[0044] Step 211, obtaining and determining whether the total mileage stored in the main controller is a valid value.

[0045] Step 212: If the total mileage stored in the main controller is a valid value, the total mileage stored in the main controller is used as the total mileage of the vehicle up to the last time it switched from the start state to the stop state.

[0046] Step 213: If the total mileage stored in the main controller is an invalid value, the total mileage stored in the auxiliary controller is used as the total mileage of the vehicle up to the last time it switched from the start state to the stop state.

[0047] In the present application, it should be noted that each time the vehicle switches from the start state to the stop state, its main controller and each auxiliary controller will update and store the total mileage. However, if the main controller is replaced or damaged, it is possible that the total mileage stored in the main controller when the vehicle last switched from the start state to the stop state will be lost, that is, the total mileage stored in the main controller is abnormal, for example, the total mileage is 0. Based on this, when the vehicle switches from the current start state to the stop state, the present application, after obtaining the total mileage stored in the main controller, also determines whether the total mileage stored in the main controller is a valid value.

[0048] If the total mileage stored in the main controller is a valid value, it means that there is no abnormality in the total mileage stored in the main controller, and the total mileage stored in the main controller is used as the total mileage of the vehicle until the last time it switched from the start state to the stop state. If the total mileage stored in the main controller is an invalid value, it means that there is an abnormality in the total mileage stored in the main controller, and the total mileage stored in the auxiliary controller can be used as the total mileage of the vehicle until the last time it switched from the start state to the stop state.

[0049] In the present application, it should be noted that if the total mileage stored in the auxiliary controller is an invalid value, the total mileage of the vehicle up to the last time it switched from the start state to the stop state can be defined as an invalid value.

[0050] In step 220, the single driving mileage of the vehicle in the current startup state calculated by the main controller and each of the auxiliary controllers is obtained.

[0051] In the present application, when the vehicle is in the startup state, the main controller and each auxiliary controller will calculate the single mileage of the vehicle in the current startup state in real time. Specifically, obtaining the single mileage of the vehicle in the current startup state calculated by the main controller and each auxiliary controller can be performed according to the following steps 221 to 222:

[0052] Step 221, when it is detected that the vehicle is in the starting state, the vehicle speed signal value of the vehicle at each moment is read in real time.

[0053] Step 222, based on the vehicle speed signal value at each moment, the single trip mileage of the vehicle in the current start state is calculated and updated in real time until it is detected that the vehicle switches from the current start state to the stop state.

[0054] In the present application, a sensor for collecting vehicle speed model values ​​will be configured in the vehicle, and when it is detected that the vehicle is in the starting state, the sensor collects the vehicle speed signal value, for example, the vehicle speed signal value is collected every 10ms, and the collected vehicle speed signal value will be transmitted to the CAN bus, and the main controller and each auxiliary controller will read the vehicle speed signal value of the vehicle at each moment in real time from the CAN bus.

[0055] After reading the vehicle speed signal value, the main controller and each auxiliary controller can calculate and update the single mileage of the vehicle in the current start-up state in real time according to the vehicle speed signal value at each moment, until it is detected that the vehicle switches from the current start-up state to the stop state. Specifically, a vehicle speed-time curve can be constructed according to the read vehicle speed signal value and the corresponding reading time, and then the constructed vehicle speed-time curve is integrated to obtain the single mileage in the current entire start-up state. It can be understood that the higher the reading frequency of the vehicle speed signal value, the more accurate the calculated single mileage of the vehicle in the current start-up state.

[0056] In the present application, after reading the vehicle speed signal value at each moment in real time, the following steps 2211 to 2212 may also be performed:

[0057] Step 2211, determining whether the vehicle speed signal value at each moment is a valid value.

[0058] Step 2212: If the vehicle speed signal value at each moment is an invalid value, the vehicle speed signal value at each moment is assigned a value of 0.

[0059] It should be noted that in the process of the main controller and each auxiliary controller reading the vehicle speed signal value from the CAN bus in real time, due to various reasons, the vehicle speed signal value may be abnormally read, for example, the vehicle speed signal value is not read, and the read vehicle speed signal value is abnormally high. If the vehicle speed signal value read at a certain moment is abnormal, the vehicle speed signal value is determined to be an invalid value, and the vehicle speed signal value of the vehicle at that moment can be assigned to 0.

[0060] In step 230, the mileage upper limit of the vehicle in the current startup state is obtained, and the maximum single mileage that is less than or equal to the mileage upper limit is selected from the single mileages calculated by the main controller and each of the auxiliary controllers as the current single mileage.

[0061] In the present application, obtaining the upper limit of the mileage of the vehicle in the current startup state may be performed according to the following step 231:

[0062] Step 231, obtaining a preset mileage value as the mileage upper limit of the vehicle in the current startup state. In this step, the maximum mileage of the vehicle when it is fully charged or fully fueled can be used as the mileage upper limit of the vehicle in the current startup state.

[0063] In the present application, obtaining the upper limit of the mileage of the vehicle in the current startup state may also be performed according to the following step 232:

[0064] Step 232, obtain the fuel consumption / electricity of the vehicle in the current startup state, and determine the upper limit of the mileage of the vehicle in the current startup state based on the fuel consumption / electricity. In this step, the fuel / electricity consumption of the vehicle under a preset working condition (such as a high-speed working condition) can be pre-tested, and the upper limit of the mileage of the vehicle in the current startup state can be calculated based on the fuel consumption / electricity and the fuel / electricity consumption.

[0065] In this application, the following step 232 may also be performed:

[0066] Step 233: If the single driving mileages respectively calculated by the main controller and each of the auxiliary controllers are greater than the driving mileage upper limit, the current single driving mileage is determined to be 0.

[0067] It can be understood that if the single driving mileage is greater than the driving mileage upper limit, it means that the calculated single driving mileage is abnormal, and the current single driving mileage can be defined as 0 at this time.

[0068] In the present application, the main controller and each of the auxiliary controllers calculate the single driving mileage of the vehicle in the current startup state according to the vehicle speed signal value read at each time. Since each controller may have abnormal reading of the vehicle speed signal value, in the present application, the accuracy of the current single driving mileage can be guaranteed by selecting the maximum single driving mileage that is less than or equal to the driving mileage upper limit value from the single driving mileages calculated by the main controller and each of the auxiliary controllers as the current single driving mileage.

[0069] In step 240, based on the current single mileage, the total mileage of the vehicle up to the last time it switched from the start state to the stop state is updated, and the updated total mileage is stored as the total mileage of the vehicle up to the current time it switched from the start state to the stop state.

[0070] In the present application, specifically, for example, the total mileage of the vehicle as of the last time it switched from the start state to the stop state is 28,000 kilometers. If the current single mileage is 80 kilometers, then the updated total mileage is 28,000+80=28,080 kilometers. 28,080 kilometers can be stored as the total mileage of the vehicle as of the current time it switched from the start state to the stop state.

[0071] It should be noted that the main controller can store the updated total mileage in the E side (after recording in the E side, the data will not be lost after hibernation).

[0072] In the present application, after storing the updated total mileage as the total mileage of the vehicle up to the time when the current start state is switched to the stop state, the following steps 251 to 252 may also be performed:

[0073] Step 251, determining whether the at least one auxiliary controller stores the updated total mileage.

[0074] Step 252: If the at least one auxiliary controller stores the updated total mileage, clear the single mileage of the vehicle in the current startup state calculated by the main controller.

[0075] In this application, in order to make those skilled in the art better understand this application, Figure 3 The vehicle mileage data processing method proposed in this application is explained in an overall manner using a specific embodiment.

[0076] See also Figure 3 , shows an overall flow chart of the main controller processing vehicle mileage data according to an embodiment of the present application.

[0077] In the present application, based on the proposed technical solution, compared with the existing solution that only updates the total mileage data of the vehicle through a certain controller, the present application updates the total mileage data of the vehicle through multiple controllers (i.e., a main controller and multiple auxiliary controllers), which can improve the accuracy of the vehicle mileage data processing. Specifically, since the communication between the various devices in the vehicle is mainly based on the CAN bus when the vehicle is traveling each time, it is easy to cause data transmission loss or inaccuracy. For example, the controller obtains the vehicle speed data from the vehicle CAN bus. Due to the possibility of abnormal speed signal received from the CAN bus, the accuracy of the single mileage calculated by the controller based on the vehicle speed data obtained from the vehicle CAN bus cannot be guaranteed, and then the accuracy of the total mileage of the vehicle updated based on the obtained single mileage cannot be guaranteed. In the present application, multiple controllers simultaneously receive the vehicle speed signal in the CAN bus, and each controller calculates the single mileage based on the obtained speed signal, and then the main controller selects an optimal single mileage from the single mileage calculated by each controller as the current single mileage, which can ensure that the final single mileage is calculated based on the vehicle speed signal with the highest accuracy. In this way, the accuracy of the current single driving mileage is improved, thereby improving the accuracy of the vehicle's total driving mileage updated based on the current single driving mileage, and further improving the accuracy of vehicle mileage data processing.

[0078] In the present application, a main controller is proposed, and the main controller is used to execute the vehicle mileage data processing method as described above.

[0079] Reference Figure 4 , shows a flow chart of another vehicle mileage data processing method in an embodiment of the present application, wherein the vehicle includes a main controller and at least one auxiliary controller, and the vehicle mileage data processing method can be executed by a device with a computing and processing function, for example, it can be executed by any of the auxiliary controllers, refer to Figure 4 As shown, the vehicle mileage data processing method includes at least steps 410 to 450, which are described in detail as follows:

[0080] In step 410, in response to the vehicle switching from the current start state to the stop state, the total mileage updated by the main controller is obtained, and the total mileage of the vehicle up to the last time it switched from the start state to the stop state is updated.

[0081] In the present application, when it is detected that the vehicle switches from the current start state to the stop state, the auxiliary controller can obtain the total mileage updated by the main controller. Specifically, when the vehicle switches from the current start state to the stop state, the main controller will update the total mileage of the vehicle up to the last time it switched from the start state to the stop state. Therefore, the auxiliary controller can communicate with the main controller to obtain the total mileage updated by the main controller.

[0082] In the present application, in addition to obtaining the total mileage updated by the main controller, the auxiliary controller also updates the total mileage of the vehicle as of the last time it switched from the start state to the stop state, thereby obtaining the total mileage updated by the auxiliary controller.

[0083] In step 420, it is determined whether the total mileage updated by the main controller is a valid value.

[0084] It should be noted that when the auxiliary controller obtains the updated total mileage from the main controller, there may be abnormalities in the total mileage, for example, the updated total mileage does not exist in the main controller, or a message is lost when obtaining the total mileage updated by the main controller. Based on this, in step 420, it is necessary to determine whether the total mileage updated by the main controller is a valid value to ensure that the total mileage updated from the main controller is accurate.

[0085] In step 430 , if the total mileage updated by the main controller is a valid value, the total mileage updated by the main controller is stored as the total mileage of the vehicle up to the time when the current start state is switched to the stop state.

[0086] In the present application, if the total mileage updated by the main controller is a valid value, it means that the auxiliary controller obtains the updated total mileage from the main controller without any abnormality. At this time, the total mileage updated by the main controller is directly stored as the total mileage of the vehicle from the time the current start state is switched to the stop state.

[0087] It should be noted that the auxiliary controller can store the updated total mileage in the E side (after recording in the E side, the data will not be lost after hibernation).

[0088] In step 440, if the total mileage updated by the main controller is an invalid value, it is determined whether the total mileage updated by any one of the auxiliary controllers is a valid value.

[0089] In the present application, if the total mileage updated by the main controller is an invalid value, it means that an abnormality has occurred in the acquisition of the updated total mileage by the auxiliary controller from the main controller. At this time, it is determined whether the total mileage updated by any of the auxiliary controllers is a valid value.

[0090] In step 450 , if the total mileage updated by any one of the auxiliary controllers is a valid value, the total mileage updated by any one of the auxiliary controllers is stored as the total mileage of the vehicle up to the time when the current start state is switched to the stop state.

[0091] Furthermore, in the present application, the following step 460 may also be performed:

[0092] Step 460: If the total mileage updated by the at least one auxiliary controller is an invalid value, define the invalid value as the total mileage of the vehicle up to the time when the current start state is switched to the stop state and store it.

[0093] In the present application, if the total mileage updated by any one of the auxiliary controllers is an invalid value, it can be determined whether the total mileage updated by other auxiliary controllers except for the any one of the auxiliary controllers is an invalid value. If the total mileage updated by other auxiliary controllers is a valid value, the total mileage updated by other auxiliary controllers is stored as the total mileage of the vehicle when the current start state is switched to the stop state. If the total mileage updated by at least one auxiliary controller (i.e., all auxiliary controllers) is an invalid value, the reason may be that other basic data obtained by all auxiliary controllers for calculating the total mileage are abnormal.

[0094] In order to help those skilled in the art better understand the above step 410, that is, how to update the total mileage of the vehicle up to the last time the vehicle switched from the start state to the stop state, the following steps 411 to 415 may be performed:

[0095] Step 411, obtaining and determining whether the total mileage of the vehicle up to the last time it switched from the start state to the stop state stored in any one of the auxiliary controllers is a valid value.

[0096] In the step of updating the total mileage of the vehicle as of the last time it switched from the start state to the stop state, first obtain the total mileage of the vehicle as of the last time it switched from the start state to the stop state stored in any one of the auxiliary controllers, and determine whether it is a valid value. It should be noted here that since the auxiliary controller may be replaced, if the auxiliary controller has been replaced, the total mileage stored in the history will be cleared. Because, in order to ensure that the total mileage updated by the auxiliary controller is accurate, the present application can determine whether the total mileage of the vehicle as of the last time it switched from the start state to the stop state stored in any one of the auxiliary controllers is a valid value.

[0097] Step 412, if the total mileage of the vehicle as of the last time it switched from the start state to the stop state stored in any of the auxiliary controllers is a valid value, then the current single trip mileage of the vehicle in the current start state determined by the main controller is obtained, and based on the current single trip mileage, the total mileage of the vehicle as of the last time it switched from the start state to the stop state is updated.

[0098] In the present application, a sensor for collecting vehicle speed model values ​​will be configured in the vehicle, and when it is detected that the vehicle is in the starting state, the sensor collects the vehicle speed signal value, for example, the vehicle speed signal value is collected every 10ms, and the collected vehicle speed signal value will be transmitted to the CAN bus, and the main controller and each auxiliary controller will read the vehicle speed signal value of the vehicle at each moment in real time from the CAN bus.

[0099] After reading the vehicle speed signal value, the main controller and each auxiliary controller can calculate and update the single mileage of the vehicle in the current start-up state in real time according to the vehicle speed signal value at each moment, until it is detected that the vehicle switches from the current start-up state to the stop state. Specifically, a vehicle speed-time curve can be constructed according to the read vehicle speed signal value and the corresponding reading time, and then the constructed vehicle speed-time curve is integrated to obtain the single mileage in the current entire start-up state. It can be understood that the higher the reading frequency of the vehicle speed signal value, the more accurate the calculated single mileage of the vehicle in the current start-up state.

[0100] It should be noted that the main controller will determine the current single driving mileage of the vehicle in the current startup state. Specifically, the main controller and each of the auxiliary controllers calculate the single driving mileage of the vehicle in the current startup state according to the vehicle speed signal value read at each time. Since each controller may have abnormal reading of the vehicle speed signal value, therefore, in this application, the accuracy of the current single driving mileage can be guaranteed by selecting the maximum single driving mileage that is less than or equal to the driving mileage upper limit value from the single driving mileages calculated by the main controller and each of the auxiliary controllers. Furthermore, after the main controller determines the current single driving mileage of the vehicle in the current startup state, any of the auxiliary controllers can directly obtain it from the main controller.

[0101] In the present application, specifically, for example, the effective total mileage of the vehicle as of the last time it switched from the start state to the stop state is 28,000 kilometers. If the current single mileage is 80 kilometers, then the updated total mileage is 28,000+80=28,080 kilometers. 28,080 kilometers can be stored as the total mileage of the vehicle as of the current time it switched from the start state to the stop state.

[0102] Step 413, if the total mileage of the vehicle stored in the at least one auxiliary controller up to the last time it switched from the start state to the stop state is an invalid value, then obtain and determine whether the total mileage updated by the main controller is a valid value.

[0103] In the present application, if the total mileage of the vehicle until the last time it switched from the start state to the stop state stored in any of the auxiliary controllers is an invalid value, it can be determined whether the total mileage of the vehicle until the last time it switched from the start state to the stop state stored in other auxiliary controllers other than the any of the auxiliary controllers is an invalid value. If the total mileage of the vehicle until the last time it switched from the start state to the stop state stored in other auxiliary controllers is a valid value, then based on the current single trip of the vehicle in the current start state determined by the main controller, the total mileage of the vehicle until the last time it switched from the start state to the stop state is updated. If the total mileage of the vehicle until the last time it switched from the start state to the stop state stored in other auxiliary controllers is an invalid value, that is, the total mileage of the vehicle until the last time it switched from the start state to the stop state stored in at least one auxiliary controller (that is, all auxiliary controllers) is an invalid value, it means that all auxiliary controllers may have been replaced, and the total mileage stored in the history may be cleared. At this time, it is possible to obtain and determine again whether the total mileage updated by the main controller is a valid value.

[0104] Step 414: If the total mileage updated by the main controller is a valid value, the total mileage updated by the main controller is determined as the total mileage updated by any one of the auxiliary controllers.

[0105] In the present application, if the total mileage updated by the main controller is a valid value, it means that the auxiliary controller obtains the updated total mileage from the main controller without any abnormality. At this time, the total mileage updated by the main controller is directly used as the total mileage updated by any auxiliary controller.

[0106] Step 415: If the total mileage updated by the main controller is an invalid value, the invalid value is defined as the total mileage updated by any auxiliary controller.

[0107] In this application, in order to make those skilled in the art better understand this application, Figure 5 and Figure 6 Another specific embodiment is used to explain the vehicle mileage data processing method proposed in this application as a whole.

[0108] See also Figure 5 , shows a flow chart of an auxiliary controller processing vehicle mileage data according to an embodiment of the present application.

[0109] See also Figure 6 , shows a flow chart of an auxiliary controller processing vehicle mileage data according to an embodiment of the present application.

[0110] In the present application, based on the proposed technical solution, compared with the existing solution of updating the total mileage data of the vehicle only through a certain controller, the present application updates the total mileage data of the vehicle through multiple controllers (i.e., a main controller and multiple auxiliary controllers), which can improve the accuracy of the vehicle mileage data processing. Specifically, the auxiliary controller first updates its own total mileage that needs to be stored based on the total mileage updated by the main controller. When the total mileage updated by the main controller is an invalid value, the auxiliary controller itself updates the total mileage of the vehicle and stores it. In this way, the loss of total mileage caused by hardware replacement of the controller and other reasons can be avoided. By synchronizing the updated total mileage, the total mileage stored in the auxiliary controller can be synchronized to the main controller when the total mileage in the subsequent main controller is abnormal, which can ensure that the updated total mileage is not lost and the error is small, thereby improving the accuracy of the vehicle mileage data processing.

[0111] In the present application, an auxiliary controller is proposed, which is used to execute the vehicle mileage data processing method as described above.

[0112] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, which includes the main controller as described above and at least one auxiliary controller as described above.

[0113] In order to make those skilled in the art better understand the present application, Figure 7 Another specific embodiment is used to illustrate the logic of a vehicle in processing vehicle mileage data.

[0114] See also Figure 7 , shows a flow chart of a main controller and an auxiliary controller jointly processing vehicle mileage data according to an embodiment of the present application.

[0115] Based on the technical solution proposed in this application, compared with the existing solution of updating the total mileage data of the vehicle only through a certain controller, this application updates the total mileage data of the vehicle through multiple controllers (i.e., a main controller and multiple auxiliary controllers), which can improve the accuracy, stability and robustness of vehicle mileage data processing. Specifically:

[0116] On the one hand, since the communication between various devices in the vehicle is mainly based on the CAN bus when the vehicle is driving, it is easy to lose or inaccurate data transmission. For example, the controller obtains the vehicle speed data from the vehicle CAN bus. Due to the possibility of abnormal speed signal received from the CAN bus, the accuracy of the single driving mileage calculated by the controller based on the vehicle speed data obtained from the vehicle CAN bus cannot be guaranteed, and then the accuracy of the vehicle total driving mileage updated based on the obtained single driving mileage cannot be guaranteed. In this application, multiple controllers simultaneously receive the vehicle speed signal in the CAN bus, and each controller calculates the single driving mileage based on the obtained speed signal, and then the main controller selects an optimal single driving mileage from the single driving mileage calculated by each controller as the current single driving mileage, which can ensure that the final single driving mileage is calculated based on the vehicle speed signal with the highest accuracy. In this way, the accuracy of the current single driving mileage is improved, thereby improving the accuracy of the vehicle total driving mileage updated based on the current single driving mileage, and then improving the accuracy of vehicle mileage data processing.

[0117] On the other hand, since the vehicle controller may need to be replaced due to damage or aging, this may easily lead to the possibility of loss of the historical total mileage data stored in the vehicle controller. In the existing scheme, if the total mileage data stored in a vehicle controller is lost, the total mileage data updated by the vehicle controller will also be inaccurate, thereby showing that the stability of vehicle mileage data processing is low, affecting the user experience. The present application updates the total mileage data of the vehicle through multiple controllers. When the total mileage data stored in any controller is lost, the controller can synchronously update the latest total mileage data from other controllers, thereby ensuring that the total mileage data will not be lost, thereby improving the stability and robustness of vehicle mileage data processing and improving user experience.

[0118] In practical applications, this application proposes a strategy for the main controller and the auxiliary controller to calculate and store the total mileage at the same time, and a strategy for multiple controllers to calculate the total mileage at the same time, and the main controller arbitrates to select the optimal calculation result, and updates the total mileage at the same time. When the auxiliary controller updates the total mileage, it gives priority to the optimal calculation result selected by the main controller, so that the total mileage information of the main controller and the auxiliary controller is changed synchronously to avoid cumulative errors in the calculation results between multiple controllers. At the same time, multiple controllers memorize and store the total mileage at the same time. When the hardware of the main controller is damaged and replaced, the total mileage of the main controller can be updated according to the total mileage memorized by the auxiliary controller; when the auxiliary controller is replaced, the total mileage can also be updated according to the total mileage memorized by the main controller.

[0119] By using the technical strategy proposed in this application, it is possible to avoid the negative perception caused by the instrument display errors due to the problem of a single controller receiving abnormal CAN signals, and at the same time effectively improve the accuracy of the total mileage calculation results (for example, during a vehicle driving process, the main controller receives abnormal vehicle speed CAN signals 10 times, and the auxiliary controller receives abnormal vehicle speed CAN signals 5 times, then the single mileage calculated by the auxiliary controller will be more accurate than the single mileage calculated by the main controller. Therefore, the main controller will be able to display the total mileage determined based on the single mileage of the auxiliary controller on the instrument for update). In addition, after the main controller is replaced, the total mileage of the main controller can also be updated according to the total mileage memorized in the auxiliary controller, and the correct total mileage can be displayed on the instrument, effectively improving the accuracy of the total mileage display, improving the accuracy of the control logic and calculation results, and avoiding obvious faults / inaccuracies in functions that the user directly contacts.

[0120] Based on the same inventive concept, an embodiment of the present application also provides a computer program product, which includes computer instructions stored in a computer-readable storage medium and suitable for being read and executed by a processor, so that a computer device having the processor executes the vehicle mileage data processing method as described above.
