At present, most vehicles have a maintenance reminding function, namely, the vehicle owner is reminded to replace three filters (namely an oil filter, a fuel filter and an air filter) and engine oil according to a certain period. In the conventional maintenance reminding function, the maintenance period for reminding the maintenance of the vehicle is usually a fixed value set in advance by the vehicle manufacturer. However, in different geographical environments, the factors such as temperature and extreme pressure are different, and the fixed value is not necessarily suitable for the current vehicle, so that the maintenance period is set inaccurately, and the maintenance reminding cannot be timely and accurately performed subsequently. In order to solve the technical problem, the present application provides a vehicle maintenance reminding method, apparatus, vehicle-mounted device and storage medium, including: acquiring current position information of a vehicle; determining a target maintenance cycle matched with the current position area of the vehicle according to the current position information of the vehicle; obtaining maintenance state information of the vehicle, wherein the maintenance state information comprises newly increased mileage information and/or newly increased running time information of the vehicle after the last maintenance; and reminding vehicle maintenance according to the target maintenance period and the maintenance state information. The target maintenance period is determined according to the current position information of the vehicle, namely the target maintenance period is a maintenance period suitable for the current position area condition of the vehicle, so that the accuracy of determining the vehicle maintenance period can be improved, the follow-up vehicle maintenance reminding according to the target maintenance period and the maintenance state information of the vehicle is more accurate, and the accuracy of the vehicle maintenance reminding is improved.

The first embodiment is as follows:

fig. 1 is a schematic flowchart illustrating a vehicle maintenance reminding method according to an embodiment of the present application, where the vehicle maintenance reminding method is applied to an On-Board device, that is, an electronic device capable of accessing an On-Board Diagnostics (OBD) interface of a vehicle and communicating with the vehicle. The vehicle maintenance reminding method shown in fig. 1 is described in detail as follows:

in S101, the current position information of the vehicle is acquired.

In the embodiment of the application, the current position information of the vehicle can be acquired after the maintenance setting instruction is received. The maintenance setting instruction is specifically an instruction for resetting maintenance cycle data of the vehicle generated by a user by operating a physical key or a touch screen of the vehicle-mounted device after the vehicle-mounted device is connected to an OBD interface of the vehicle, and the maintenance setting instruction may also be referred to as a maintenance lamp zeroing instruction. Alternatively, the vehicle-mounted device may automatically acquire the current location information of the vehicle every preset time period.

In one possible implementation, the vehicle-mounted device has a Global Positioning System (GPS) chip, and the vehicle-mounted device instructs the vehicle-mounted device to acquire Positioning coordinates of the GPS chip as current position information of the vehicle. In another possible implementation, the current location information of the vehicle may be manually input by a user.

In S102, a target maintenance cycle matching the current location area where the vehicle is located is determined according to the current location information of the vehicle.

After the current position information of the vehicle is acquired, a maintenance period matched with the current position area where the vehicle is located can be determined as a target maintenance period by inquiring maintenance strategy information prestored in the local vehicle-mounted equipment or other equipment. The current position area where the current vehicle is located is determined according to the current position information of the vehicle.

In one embodiment, weather data and/or geographic data of the area where the vehicle is located can be queried through a weather website according to the position information of the vehicle. And then, calculating a target maintenance period matched with the current vehicle according to the weather data and/or the geographic data and a preset algorithm.

In S103, maintenance state information of the vehicle is obtained, where the maintenance state information includes newly added mileage information and/or newly added running time information of the vehicle after the last maintenance.

Generally, a maintenance cycle of a vehicle includes information of a maintenance mileage indicating a mileage that the vehicle can travel after completing one maintenance and/or a maintenance period indicating a period that the vehicle can travel after completing one maintenance. When the vehicle reaches the maintenance mileage or the maintenance mileage, a vehicle maintenance prompt is required to remind the user to perform vehicle maintenance again in time. Accordingly, in the embodiment of the present application, after the vehicle is maintained, newly added mileage information and/or newly added running time information of the vehicle after the last maintenance needs to be obtained to determine whether the vehicle needs to be maintained again at present in time. The information of the newly added maintenance mileage of the vehicle and/or the information of the newly added running time of the vehicle is called as maintenance state information of the vehicle.

Specifically, the embodiment of the application can automatically acquire the maintenance state information of the vehicle in real time or at preset time intervals. In one embodiment, in step S101, specifically, after a vehicle maintenance is completed, the current position information of the vehicle acquired after receiving the maintenance setting instruction is completed, and a maintenance zeroing setting is completed through step S101 and step S102, and correspondingly, after the step S103 of the embodiment of the present application is set for the maintenance zeroing, the maintenance state information of the vehicle is automatically acquired every preset time period. In another embodiment, in step S101, specifically, after the vehicle maintenance is completed, the current position information of the vehicle is automatically acquired every preset time period, and after the current position information of the vehicle is acquired each time, the current target maintenance cycle is automatically determined through step S102, and correspondingly, in step S103 in this embodiment, the maintenance state information of the vehicle may be acquired while the current position information of the vehicle is acquired in step S101.

In step S104, a vehicle maintenance prompt is performed according to the target maintenance cycle and the maintenance state information.

In the embodiment of the present application, the target maintenance period specifically includes information of the target maintenance mileage and/or the target maintenance duration. After the maintenance state information is acquired, the newly added vehicle mileage information in the maintenance state information may be compared with the target maintenance mileage in the target maintenance period, or the newly added vehicle driving duration information in the maintenance state information may be compared with the target maintenance duration in the target maintenance period, and when a comparison result meets a certain condition (for example, the newly added vehicle mileage information is closer to or equal to the target maintenance mileage, or the newly added vehicle driving duration information is closer to or equal to the target maintenance duration), a vehicle maintenance prompt may be performed. Wherein the vehicle maintenance reminder may include: an indicator light (maintenance light for short) for reminding a vehicle of needing maintenance is turned on or flickers on an instrument panel of the vehicle; or sending out preset voice reminding information; or sending short message reminding information to a terminal (such as a mobile phone) of the owner of the vehicle; therefore, the owner of the vehicle is reminded to maintain the vehicle in time.

In the embodiment of the application, the target maintenance period is determined according to the current position information of the vehicle, that is, the target maintenance period is a maintenance period adapted to the current position area condition of the vehicle, so that the accuracy of determining the vehicle maintenance period can be improved, and further the subsequent vehicle maintenance reminding according to the target maintenance period and the maintenance state information of the vehicle is more accurate, and the accuracy of the vehicle maintenance reminding is improved.

In the embodiment of the application, at least 2 maintenance strategies suitable for the vehicle type information can be created in advance according to the vehicle type information of the current vehicle, and the maintenance strategies at least comprise maintenance cycle information. For example, if the vehicle type information of the current vehicle is vehicle type 1, two maintenance strategies corresponding to the vehicle type 1 are generated: policy 1 and policy 2. The information of the preset maintenance period contained in the strategy 1 is as follows: the maintenance mileage of 6000 km and/or the maintenance days of 200 days, and the preset maintenance period information contained in the policy 2 is: 10000 km maintenance mileage and/or 365 days maintenance.

And then, according to the climate conditions of the position areas which are divided in advance and are possible to run by the vehicle, constructing the mapping relation corresponding to each position area and the maintenance strategy, and storing the mapping relation so as to accurately determine the target maintenance period according to the mapping relation and the position area where the vehicle is located. For example, it is assumed that the location areas divided in advance include a northeast area and a southeast area, and since the northeast area is relatively dry in air and cold in winter, the environment is relatively severe, and vehicles located in the northeast area need to perform the next vehicle maintenance in a shorter period than vehicles located in the southeast area, the mapping relationship between the northeast area and the policy 1 and the mapping relationship between the southeast area and the policy 2 may be constructed and stored.

According to the embodiment of the application, the maintenance strategy can be generated in advance, the mapping relation between the position area and the maintenance strategy is constructed and stored, so that the target maintenance period matched with the current position area where the vehicle is located can be accurately determined according to the stored mapping relation subsequently, and the accuracy of vehicle maintenance reminding can be improved.

In the embodiment of the application, the current position area of the vehicle can be determined according to the current position information. In one embodiment, it is assumed that the vehicle-mounted device or the other device divides each location area in advance (by province, city, county, or other designated division methods), each location area corresponds to one location coordinate range, and the current location information of the vehicle is the location coordinate acquired by the GPS chip, so that the current location area of the vehicle can be determined by determining in which location coordinate range the currently acquired location coordinate falls.

After the current position area is determined, the mapping relation between the position area and the maintenance strategy which is constructed and stored in advance is inquired, and the maintenance strategy matched with the current position area is determined as a target maintenance strategy.

After the target maintenance strategy is determined, the maintenance period information in the target maintenance strategy is obtained, and the maintenance period information is determined as the target maintenance period.

acquiring vehicle type information of the vehicle;

acquiring the target maintenance strategy returned by the server;

In the embodiment of the application, the mapping relationship between the location area and the maintenance policy is specifically stored in the server, and the vehicle-mounted device may perform remote communication with the server through a mobile communication network such as 3G, 4G, or 5G, so as to obtain the corresponding maintenance policy and determine the current target maintenance cycle.

In one embodiment, the obtaining of the model information of the vehicle may be obtaining the model information of the vehicle manually input by the user. In another embodiment, the obtaining of the vehicle type information of the vehicle may be that the vehicle-mounted device automatically communicates with an Electronic Control Unit (ECU) of the vehicle, so as to automatically obtain the vehicle type information of the vehicle, and specifically may include:

a1: and sending a Vehicle Identification Number (VIN) code reading instruction to the Vehicle. Since the vehicle-mounted device cannot confirm the communication protocol adopted by the vehicle at the beginning, VIN code reading instructions corresponding to each common vehicle protocol are sequentially sent once until the vehicle returns the VIN code information. Common vehicle protocols include a Controller Area Network (CAN), a Keyword Protocol (KWP), an ISO9141 Protocol, a Pulse Width Modulation (PWM) Protocol, a Variable Pulse Width (VPW) Protocol, and the like, and communication parameters and VIN read instructions of each Protocol are different. Illustratively, the communication pins of the CAN protocol are 6,14, the baud rate is 500K, and the VIN code reading instruction is as follows: 0x0807df 0209020000000000.

A2: and acquiring the VIN code returned by the vehicle, and analyzing the VIN code to obtain the vehicle type information of the vehicle.

In the embodiment of the present application, the server specifically includes a preset mapping relationship database, and the mapping relationship database stores mapping relationships between location areas, vehicle types, and maintenance strategies. After the vehicle type information of the vehicle is acquired, the current position information of the vehicle and the vehicle type information can be sent to the server together, so that the server can determine the current position area where the vehicle is located according to the current position information, and determine a maintenance strategy which is mapped and stored with the current position area and the vehicle type information from the preset mapping relation database as a target maintenance strategy.

After determining the target maintenance policy, the server may return (i.e., send) the target maintenance policy to the vehicle-mounted device according to the embodiment of the present application. And the vehicle-mounted equipment receives the target maintenance strategy returned by the server.

After that, the in-vehicle device may acquire the maintenance cycle information from the target maintenance policy and determine the maintenance cycle information as the target maintenance cycle.

In the embodiment of the application, the mapping relation between the position area and the maintenance strategy is specifically stored in the mapping relation database of the server, so that the local storage space of the vehicle-mounted equipment can be saved, a plurality of vehicle-mounted equipment can be supported to share the mapping relation database stored by the same server, and the intelligence and the efficiency of determining the target maintenance cycle are improved.

Optionally, the step S104 specifically includes:

In the embodiment of the present application, a vehicle maintenance prompt is performed directly according to the target maintenance cycle determined in step S102 and matched with the current position of the vehicle, and by combining the maintenance state information obtained in step S103.

Specifically, difference calculation is performed according to a target maintenance mileage in the target maintenance period and vehicle new mileage information in the maintenance state information, and a difference between the target maintenance mileage and the vehicle new mileage information is determined as a mileage difference. And then, judging the size relationship between the mileage difference value and a preset mileage threshold value.

Specifically, difference calculation is performed according to a target maintenance duration in the target maintenance period and vehicle newly-added duration information in the maintenance state information, and a difference between the target maintenance duration and the vehicle newly-added duration information is determined as a duration difference. And then, judging the relation between the time length difference and a preset time length threshold.

And if the mileage difference value is determined to be smaller than the preset mileage threshold value after the relationship between the mileage difference value and the preset mileage threshold value is judged, or the duration difference value is determined to be smaller than the preset duration threshold value after the relationship between the duration difference value and the preset duration threshold value is judged, vehicle maintenance reminding is carried out so as to remind a vehicle owner of maintaining the vehicle again in time.

Exemplarily, the target maintenance mileage is 6000 kilometers, the current vehicle newly-increased mileage information is 5999 kilometers, and the preset mileage threshold value is 5 kilometers, then the mileage difference value between the target maintenance mileage and the vehicle newly-increased mileage information is 1 kilometer, and the vehicle maintenance reminding is performed at this time because the mileage difference value is smaller than the preset mileage threshold value.

For example, the target maintenance duration is set to 200 days, the current vehicle newly-added duration information is 199 days, and the preset duration threshold is 2 days, then the duration difference between the target maintenance duration and the vehicle newly-added duration information is 1 day, and since the duration difference is smaller than the preset duration threshold, the vehicle maintenance reminding is performed at this time.

In the embodiment of the application, because the mileage difference value between the target maintenance mileage and the vehicle new mileage information and the time difference value between the target maintenance time and the vehicle new driving time information can be determined firstly, and the vehicle maintenance reminding is performed when the mileage difference value is smaller than the preset mileage threshold value or the time difference value is smaller than the preset time threshold value, the vehicle maintenance reminding can be accurately performed in advance according to the target maintenance cycle, so that a vehicle owner can perform vehicle maintenance in time.

Optionally, the maintenance state information further includes newly added area information, and correspondingly, performing vehicle maintenance reminding according to the target maintenance cycle and the maintenance state information specifically includes:

In an embodiment of the application, the maintenance state information further includes newly added area information, and the newly added area information is information of each location area through which the vehicle has traveled after the last maintenance. The newly added region information has a corresponding relationship with the newly added mileage information and/or the newly added travel time information, that is, when the newly added mileage information and/or the newly added travel time information is recorded, the position region where the vehicle passes corresponding to the travel mileage or the travel time can be recorded as the newly added region information at the same time.

In the above-described step S104, after the maintenance state information of the vehicle is acquired, it is first determined whether or not the position area included in the newly added area information in the maintenance state information is greater than or equal to 2. If yes, determining a maintenance cycle corresponding to each position area in the newly added area information according to a mapping relation prestored in the local terminal or a mapping relation prestored in the server, and combining the maintenance cycles to generate a newly added maintenance cycle set. If not, the vehicle maintenance reminding is directly carried out according to the target maintenance period which is determined in the step S102 and is matched with the current position area of the vehicle and the maintenance state information in the step S103.

After the newly added maintenance cycle set is generated, a maintenance cycle with the shortest cycle may be determined from the newly added maintenance cycle set as a new target maintenance cycle, and then, a vehicle maintenance prompt may be performed according to the new target maintenance cycle and the maintenance state information.

For example, if the vehicle is driven from the Guangxi province to the Guangdong province after the last maintenance, that is, the newly added area information includes two position areas of the Guangxi province and the Guangdong province, the newly added maintenance cycle set includes a maintenance cycle corresponding to the Guangxi province and a maintenance cycle corresponding to the Guangdong province. Setting the maintenance cycle corresponding to Guangxi province as 9000 kilometers of maintenance mileage and/or 300 days of maintenance, and setting the maintenance cycle corresponding to Guangxi province as 9800 kilometers of maintenance mileage and/or 320 days of maintenance, determining that the maintenance cycle corresponding to Guangxi province is short, and at this time, not directly performing vehicle maintenance reminding with the target maintenance cycle corresponding to the current position area (Guangdong province) of the vehicle determined in step S102, but determining the maintenance cycle corresponding to Guangxi province as a new target maintenance cycle, and performing vehicle maintenance reminding according to the new maintenance cycle and the current maintenance state information.

In the embodiment of the application, when the newly added area information includes at least 2 location areas (that is, the vehicle runs through at least 2 location areas), the shortest maintenance cycle in the maintenance cycles corresponding to the location areas can be used as a new target maintenance cycle, and the vehicle maintenance reminding is performed according to the new target maintenance cycle, so that the vehicle maintenance reminding can be performed in time in consideration of the change of the location areas where the vehicle runs, and the timeliness and the accuracy of the vehicle maintenance reminding are further improved.

In the embodiment of the application, after the target maintenance period is determined, the vehicle-mounted device sends a reset instruction to the vehicle, and specifically, the reset instruction is sent to an instrument panel ECU of the vehicle through an OBD interface of the vehicle, so as to instruct an instrument panel of the vehicle to display the current reset target maintenance period. Specifically, the reset instruction may be acquired based on diagnostic protocol information of the vehicle. Specifically, the sending of the reset instruction to the vehicle may include:

b1: acquiring diagnostic protocol information of a vehicle, wherein the diagnostic protocol information comprises information of communication parameters, maintenance period setting instructions and reset instructions;

b2: establishing communication connection with the vehicle according to the diagnostic protocol information;

b3: sending the maintenance cycle setting instruction to the vehicle, wherein the maintenance cycle setting instruction comprises a target maintenance cycle;

b4: and sending the reset instruction to the vehicle to instruct an instrument panel of the vehicle to display the current target maintenance cycle.

In B1, diagnostic protocol information of the vehicle is acquired to enable communication with the vehicle according to the diagnostic protocol information. The diagnostic protocol information may include information such as communication parameters of the vehicle, an activation command, a maintenance setting command (which may also be referred to as a maintenance zeroing command), a diagnostic procedure, and the like, wherein the communication parameters may include a communication protocol type, a communication pin, a system filter ID, a baud rate, and the like. In one embodiment, the vehicle-mounted device stores diagnosis protocol information of various vehicle types in advance, and after determining the vehicle type information of the current vehicle, diagnosis protocol information corresponding to the vehicle type information can be acquired from the pre-stored diagnosis protocol information as diagnosis protocol information of the current vehicle according to the vehicle type information.

In B2, after the on-board device acquires the diagnostic protocol information of the vehicle, the on-board device sets its own communication parameters to be consistent with the communication parameters in the diagnostic protocol information according to the diagnostic protocol information, thereby establishing a communication connection between the on-board device and the vehicle. For example, according to the diagnostic protocol information, the communication parameters of the vehicle-mounted equipment are set as: CAN communication protocol, communication pins 6,14, system filter IDs 0xee20 and 0xee 60. In the embodiment of the application, the current position information of the vehicle can be acquired while or after the communication parameters of the vehicle-mounted device are set, so that after the current position information of the vehicle is acquired and the corresponding target maintenance period is acquired according to the current position information, the vehicle-mounted device can directly set the maintenance period data of the vehicle according to the target maintenance period on the premise that the communication connection with the vehicle-mounted device is established.

In B3, the maintenance cycle setting instruction refers to an instruction instructing the vehicle to set maintenance cycle data stored by the ECU of the vehicle itself as the current target maintenance cycle. The maintenance cycle setting instruction specifically includes a target maintenance cycle. In this embodiment, the diagnostic protocol information of the vehicle includes a maintenance setting command, and the information of the target maintenance cycle may be filled into the maintenance setting command and sent to the ECU of the vehicle dashboard, so that the ECU of the vehicle dashboard parses the maintenance cycle setting command, obtains the target maintenance cycle, and updates its own maintenance cycle data to the target maintenance cycle.

In B4, a reset command of the vehicle is determined according to a diagnostic protocol of the vehicle, and the reset command is transmitted to an ECU of an instrument panel of the vehicle to instruct the instrument panel of the vehicle to display a current target maintenance cycle. For example, assuming that the current target maintenance cycle is 10000 km, after the maintenance cycle data stored in the vehicle instrument panel ECU is set to 10000 km according to the target maintenance cycle, a reset instruction is sent to the vehicle instrument panel, so that the newly set target maintenance cycle is displayed on the instrument panel of the vehicle: 10000 km.

Optionally, the above diagnostic protocol information of the vehicle includes information of a verification request command, a safety verification algorithm, a safety verification command, and a maintenance cycle setting command, and correspondingly, the step B3 includes:

sending a verification request command to the vehicle;

acquiring verification information returned by the vehicle;

determining a check code according to the check information and the safety check algorithm;

sending the check code to the vehicle according to the check code and the safety check command;

and if the information which is returned by the vehicle and indicates that the verification is successful is obtained, setting maintenance cycle data of the vehicle according to the target maintenance cycle and the maintenance cycle setting command.

In the embodiment of the application, the diagnostic protocol information of the vehicle specifically further includes information of a verification request command, a safety verification algorithm, a safety verification command and a maintenance period setting command.

In the embodiment of the application, the maintenance period data of the vehicle can be set only when the vehicle-mounted equipment specifically needs to pass the safety verification of the vehicle. The vehicle-mounted device specifically acquires the verification request command from the diagnostic protocol information, and sends the verification request command to an ECU of the vehicle (specifically, an instrument panel ECU of the vehicle), so that the ECU of the vehicle returns verification information to the vehicle-mounted device. And the vehicle-mounted equipment acquires the check information returned by the vehicle, and processes the check information according to a safety check algorithm contained in the diagnosis protocol to obtain a corresponding check code. And then, filling the check code into a safety check command, and sending the check code to an ECU of the vehicle for checking. And when the information which is returned by the vehicle and indicates that the verification is successful is acquired, the vehicle-mounted equipment passes the safety verification of the vehicle, and at the moment, the vehicle-mounted equipment can set maintenance cycle data of the vehicle according to the target maintenance cycle and the maintenance cycle setting command.

In the embodiment of the present application, since the safety check can be performed before the maintenance cycle data of the vehicle is set, the safety of the vehicle maintenance setting method can be improved.

In the embodiment of the application, after the target maintenance period is determined, the instrument panel of the vehicle can be timely indicated to display the current target maintenance period through the reset instruction, so that the vehicle owner can timely learn the maintenance period of the vehicle.

Fig. 2 shows an application scenario diagram corresponding to the vehicle maintenance reminding method provided by the embodiment of the present application, and the application scenario diagram includes a vehicle 21, an on-board device 22, and a server 23. The on-board device 22 is capable of establishing a communication connection with the vehicle 21 through an OBD interface of the vehicle 21. In one embodiment, the vehicle-mounted device 22 has a Linux operating system or an Andriod operating system, and can implement the vehicle maintenance reminding method described in the first embodiment or the second embodiment by running a vehicle maintenance setting program. The in-vehicle device can also establish a communication connection with the server 23 through a mobile communication network such as 3G, 4G, 5G, or the like. In one embodiment, the vehicle-mounted device has a hardware transceiver of common vehicle protocols such as KWP, CAN, PWM, VPW, etc., and CAN communicate with each ECU of the vehicle 21 through an OBD interface of the vehicle 21; the vehicle-mounted equipment is also provided with a GPS chip which can acquire positioning information. The following specifically describes the vehicle maintenance setting method according to the embodiment of the present application, taking the application scenario shown in fig. 2 as an example scenario:

(1) the server 23 acquires the configuration command, configures the mapping relationship between the location area and the maintenance period, and stores the mapping relationship in the mapping relationship database. The configuration instructions comprise maintenance strategy making instructions and mapping relation configuration instructions. Firstly, making an instruction according to a maintenance strategy, specifically, respectively setting at least two different maintenance strategies for vehicles of each vehicle type, wherein each maintenance strategy corresponds to a maintenance period. For example, two different maintenance strategies, namely strategy 1 and strategy 2, are set for the vehicle model 1, wherein the maintenance period of the strategy 1 is 6000 km of maintenance mileage or 200 days of maintenance days; the maintenance period of strategy 2 was 10000 km maintenance mileage or 365 days maintenance days. And then, configuring a command through a mapping relation, and configuring corresponding maintenance strategies for each position area divided in advance, so that each position area is mapped and stored with one maintenance cycle. For example, a strategy 1 is configured for a vehicle type 1 with a northeast location area, corresponding to a maintenance mileage of 6000 km or a maintenance number of days of 200 days; and configuring a strategy 2 for the vehicle type 1 with the position area being the Hainan area, wherein the strategy corresponds to 10000 km of maintenance mileage or 365 days of maintenance.

(2) When the vehicle 21 needs to perform maintenance setting, that is, when the maintenance zeroing setting needs to be performed, the user inserts the in-vehicle device 22 into the OBD interface of the vehicle 21, and then presses a key designated by the in-vehicle device 22, so that the in-vehicle device 22 acquires a maintenance cycle setting instruction, and starts a vehicle maintenance setting program.

(3) Through the vehicle maintenance setting program, in-vehicle device 22 may sequentially send various protocols (for example, CAN, KWP, ISO9141, PWM, VPW, and the like) to the ECU of vehicle 51 corresponding to the VIN code reading instruction, respectively, until the VIN code information returned by vehicle 51 is acquired. For example, the communication pins of the CAN protocol are 6,14, the baud rate is 500K, and the VIN code reading instruction is 0x0807df0209020000000000, and the relevant parameters CAN be set according to the conditions, and the VIN code reading instruction corresponding to the CAN protocol is sent to the ECU of the vehicle 21.

(4) The vehicle-mounted device 22 analyzes specific vehicle type information from the VIN codes of 17 bytes according to the VIN code information returned by the vehicle 21.

(5) After the vehicle type information is determined, the in-vehicle device 22 acquires the diagnostic protocol information and the diagnostic protocol flow of the dashboard ECU of the vehicle type from the prestored diagnostic protocol file according to the vehicle type information. The diagnostic protocol information may include information such as a protocol type, a communication pin, a system filter ID, a baud rate of communication, an activation command, a maintenance cycle setting command, and a security check algorithm.

(6) The vehicle-mounted device 22 establishes communication connection with the dashboard ECU of the vehicle 21 according to the acquired diagnostic protocol information of the dashboard ECU, for example, sets the communication parameters of the vehicle-mounted device 22 as: the CAN protocol, the Baud rate is 500K, the communication pins are 6,14, and the system filter IDs are 0xee20 and 0xee 60.

(7) The onboard apparatus 22 acquires the positioning coordinates as the position information of the vehicle 21 by its own GPS chip, and uploads the acquired positioning coordinates and the vehicle type information obtained in step (4) as target information to the server 23.

(8) After the target information is acquired, the server 23 determines a position area where the current vehicle 21 is located according to the positioning coordinates included in the target information, determines a maintenance strategy that needs to be executed currently according to the position area and the vehicle type information included in the target information, and returns the determined maintenance strategy to the vehicle-mounted device 22, where the maintenance strategy carries information of a target maintenance period.

(9) The in-vehicle device 22 receives the maintenance policy, and acquires the current target maintenance cycle.

(10) The in-vehicle device 22 first performs a safety check with the instrument panel ECU of the vehicle 21 after acquiring the target maintenance cycle. Specifically, according to the acquired diagnostic protocol information, a verification request command "0 x 2701" is sent to the dashboard ECU of the vehicle 21, and a piece of verification information returned by the dashboard ECU is acquired, where the verification information includes SEED data (i.e., data that needs to be subsequently verified and calculated). For example, the check information is "0 x 670111223344", where 11223344 is the SEED data. Then, the vehicle-mounted device calculates the SEED data according to the check information and the safety check algorithm obtained from the diagnostic protocol information to obtain a check CODE, for example, the SEED data "0 x 11223344" is subjected to the safety check algorithm to obtain a corresponding CODE "0 x 55667788". Then, the check CODE is filled in the security check command, and the filled security check command "0 x 270255667788" is obtained and sent to the dashboard ECU. After receiving the check CODE, the dashboard ECU checks whether the CODE is correct, and if the CODE is correct, returns information (for example, 0x6202) indicating that the check is successful to the vehicle-mounted device.

(11) After acquiring the information indicating the successful verification, the in-vehicle device 22 confirms that it has passed the verification by the dashboard ECU, fills the target maintenance cycle in the maintenance policy into the maintenance cycle setting command acquired from the diagnostic protocol information, and transmits the maintenance cycle setting command to the dashboard ECU of the vehicle 21. For example, if the current maintenance cycle setting command is 0x2e0108 and the preset maintenance cycle is 10000 km, 10000 is converted into hexadecimal data: after 0x2710, fill the maintenance cycle setting command with the final setting command: 0x2e01082710, and sends it to the instrument panel ECU of the vehicle 21.

(12) After the instrument panel ECU of the vehicle acquires the setting command, the setting command is analyzed to obtain data: 10000, and the maintenance cycle data stored in the instrument panel ECU of the vehicle 21 is modified to 10000.

(13) The in-vehicle device 22 sends a reset instruction to the dashboard ECU of the vehicle 21, instructs the dashboard ECU to reset, and displays the current target maintenance cycle.

(14) The in-vehicle device 22 acquires maintenance state information of the vehicle, which includes newly added mileage information and/or newly added travel time length information of the vehicle after the last maintenance.

(15) The in-vehicle device 22 performs the vehicle maintenance reminding by means of voice prompt or indication of the lighting of the maintenance lamp of the vehicle when it is determined that the vehicle new mileage information is close to the target maintenance mileage or the vehicle new duration information is close to the target maintenance duration according to the target maintenance cycle and the maintenance state information.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
