Detailed Description

In order to enable a person skilled in the art to better understand the technical solutions of the present application, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.

The following describes the inventive concept of the present application, which is based on a service-oriented architecture (service-oriented architecture, SOA), the principle of which is: different functional units in the updating method of the vehicle mileage value are split, the minimum functional logic is packaged into service, and the interaction of different functional logic modules is realized by calling a service interface, so that the data interaction is realized. In the traditional software architecture, hardware and software are highly coupled, signal-based communication is not flexible and expandable, and minor functional changes can cause the adjustment of the whole vehicle software. The service-oriented architecture changes the cross-electronic control unit (Electronic Control Unit, ECU) interaction from signal-based communication to service-based communication, and the application is served, so that the intelligent vehicle is possible for random use of people under permission. The flexible deployment of the service can be realized, different vehicle type configurations can be used for different service deployment in the whole vehicle life cycle, the coupling degree between software and hardware is greatly reduced, and the software updating and upgrading are faster.

The service-oriented architecture divides the software hierarchy into: a scene service layer, a system service layer, an enhancement service layer, an atomic service layer, an Input/Output (I/O) abstraction layer, and a base service layer.

Scene service layer: the user can flexibly arrange various scenes on the premise of opening the permission according to the needs. The layer mainly calls services for the outside and then sends different request parameters to the enhanced services layer.

System service layer: and judging preconditions according to various trigger sources, and calling enhanced services to realize basic functions of vehicle control. It may receive the logic state of each actuator from the enhanced services notification down, and may notify the logic or running state of its services up, facilitating subsequent scene orchestration. The application range can be divided into 'intra-domain communication', 'inter-domain communication' and 'intra-domain non-communication' according to the function requirements.

Enhancement service layer: and carrying out parameter screening on the requests sent by the scene service layer, selecting which service is executed according to a preset priority order when a plurality of requests are received, and returning request parameters.

Atomic service layer: the influence of the change of the frequency-closed I/O abstraction layer on the enhancement layer reduces the modification of software during the function change and realizes decoupling.

I/O abstraction layer: bind with the hardware layer, mask the hardware design and specific implementation. The interface provided by the I/O abstraction layer is only visible to the atomic service layer and other levels cannot be invoked directly.

Basic service layer: similar to the system service, the requirements can be divided into "intra-domain communication", "inter-domain communication", and "intra-domain non-communication".

For easy understanding, the following describes the method for updating the mileage value of the vehicle provided by the application in detail with reference to the accompanying drawings.

Fig. 1 is a flowchart illustrating a method of updating a vehicle mileage value according to an exemplary embodiment, and as shown in fig. 1, the method of updating a vehicle mileage value includes the steps of:

s101, the electronic equipment acquires a first mileage value from a main area controller of the vehicle.

As one possible implementation manner, the electronic device sends an instruction for reading the first mileage value to a basic service layer in the main area controller; correspondingly, after receiving the reading instruction, the basic service layer acquires a first mileage value in the storage layer by calling the reading service, and sends the first mileage value to a mileage reading interface of the electronic equipment. Correspondingly, the electronic equipment acquires a first mileage value.

It should be noted that the storage layer stores mileage data of the vehicle by adopting an analog EEPROM and related basic software.

S102, the electronic equipment acquires at least one second mileage value from at least one redundant area controller of the vehicle.

Wherein a second mileage value is stored in a redundant area controller.

As one possible implementation manner, the electronic device sends an instruction for reading the second mileage value to the basic service layer of each redundant area controller in the at least one redundant area controller; correspondingly, after receiving the reading instruction, the basic service layer of each redundant area controller invokes the service to read the second mileage value in the storage layer and sends the second mileage value to the mileage reading interface of the electronic equipment. Correspondingly, the electronic device obtains at least one second mileage value.

If there are two redundant area controllers, the electronic device sends an instruction for reading the second mileage value to the basic service layer of each of the two redundant area controllers; correspondingly, after receiving the reading instruction, the basic service layer in each redundant controller invokes the service to read the second mileage value in the storage layer, and sends the two second mileage values to the mileage reading interface of the electronic device. Correspondingly, the electronic equipment acquires two second mileage values.

S103, the electronic device determines an initial mileage value from the first mileage value and at least one second mileage value.

As one possible implementation, the electronic device determines whether the main area controller is initialized, and whether the first vehicle identification code stored in the main area controller is the same as the vehicle identification code of the vehicle.

After receiving the modification operation of the user on the first mileage value, the electronic device judges whether the first mileage value is smaller than a preset mileage value, and determines an initial mileage value from the first mileage value and at least one second mileage value.

And S104, the electronic equipment updates the current mileage value of the vehicle according to the initial mileage value and the running information of the vehicle.

The running information of the vehicle comprises a speed signal and a power gear signal of the vehicle.

As one possible implementation manner, in the case that the power gear signal indicates that the power gear is on, the electronic device calculates, according to the vehicle speed signal of the vehicle, a mileage increment accumulated in a preset calculation period, and calculates, according to the mileage increment, a current mileage value of the vehicle.

In the actual application process, the running information of the vehicle can also comprise a vehicle speed effective signal; under the condition that the vehicle speed signal of the vehicle is valid and the power gear signal is on, the electronic equipment updates the current mileage value of the vehicle according to the initial mileage value and the running information of the vehicle.

If the power source gear signal of the vehicle is turned off and the vehicle speed indicated by the vehicle speed signal is not 0, the vehicle speed valid signal indicates that the vehicle speed signal is invalid.

If the vehicle speed indicated by the vehicle speed signal is greater than the preset speed threshold value, the vehicle speed signal marked by the vehicle speed effective signal is invalid.

By way of example, the preset calculation period may be 30 seconds.

According to the technical scheme provided by the embodiment of the application, the first mileage value is obtained from the main area controller of the vehicle, and the at least one second mileage value is obtained from the at least one redundant area controller of the vehicle; and determining an initial mileage value from the first mileage value and the at least one second mileage value. Further, the current mileage value of the vehicle is updated according to the initial mileage value and the running information of the vehicle. Therefore, under the condition that the regional controller of the vehicle has faults, the initial mileage value can be determined from the first mileage value and at least one second mileage value, and the current mileage value of the vehicle is updated according to the determined initial mileage value, so that the problem that the calculation of the mileage value of the vehicle is wrong or cannot be displayed due to the faults of the regional controller can be effectively reduced. In addition, since a plurality of regional controllers are used to store mileage values of the vehicle, the influence due to the life problem of the memory in the regional controllers can be greatly reduced.

In some embodiments, in order to determine whether to determine the initial mileage value from the first mileage value and the at least one second mileage value according to the verification information of the vehicle, as shown in fig. 2, in the method for updating the vehicle mileage value according to the embodiment of the present application, S103 includes the following steps:

s201, the electronic equipment judges whether the verification information of the vehicle passes the verification.

The verification information comprises a first mileage value, at least one second mileage value, a first vehicle identification code, at least one second vehicle identification code, a power supply gear signal of the vehicle and a speed signal of the vehicle; the first vehicle identification code is stored in the main zone controller and a second vehicle identification code is stored in a redundant zone controller.

As one possible implementation manner, the electronic device determines that the verification information of the vehicle passes the verification when the first mileage value and the at least one second mileage value are both smaller than the preset mileage upper limit, the data dimensions of the first vehicle identification code and the at least one second vehicle identification code are both preset data dimensions, the power supply gear signal of the vehicle indicates that the vehicle is in the energized state, and the speed indicated by the speed signal of the vehicle is smaller than the preset speed threshold.

And the electronic equipment determines that the verification information of the vehicle does not pass the verification under the condition that the first mileage value and the at least one second mileage value are greater than or equal to a preset mileage upper limit, and/or the data dimension of the at least one vehicle identification code in the first vehicle identification code and the second vehicle identification code is not the preset data dimension, and/or the power supply gear signal of the vehicle does not indicate that the vehicle is in a power-on state, and/or the speed indicated by the speed signal of the vehicle is greater than or equal to a preset speed threshold.

Illustratively, the preset data dimension is 64; the preset upper limit of mileage may be 999999 km; the preset speed threshold may be 360 kilometers per hour.

S202, under the condition that the verification information of the vehicle passes the verification, the electronic equipment determines an initial mileage value from the first mileage value and at least one second mileage value.

As one possible implementation, in the case where the main area controller is initialized, the electronic device determines a maximum value of the first mileage value and the at least one second mileage value as an initial mileage value.

If the primary zone controller is non-initialized, the electronic device determines a maximum of the first mileage value and the at least one second mileage value as an initial mileage value if the first vehicle identification code stored in the primary zone controller is not the same as the vehicle identification code of the vehicle.

In the case that the main area controller is non-initialized and the first vehicle identification code is the same as the vehicle identification code of the vehicle, responding to the modification operation of the user on the first mileage value, and if the first mileage value is smaller than the preset mileage value, determining the minimum value of the first mileage value and at least one second mileage value as an initial mileage value by the electronic device.

According to the technical scheme provided by the embodiment of the application, whether the verification information of the vehicle passes the verification is judged, and under the condition that the verification information of the vehicle passes the verification, the electronic equipment determines an initial mileage value from the first mileage value and at least one second mileage value. Therefore, the vehicle verification information is pre-verified, the vehicle verification information can be filtered in advance, and errors of the mileage value determined by errors in the vehicle verification information are avoided.

In some embodiments, in order to determine an initial mileage value from the first mileage value and at least one second mileage value, as shown in fig. 3, in the method for updating a vehicle mileage value according to the embodiment of the present application, the step S103 includes the following steps:

s301, the electronic device judges whether the main area controller is initialized.

As a possible implementation manner, if the main area controller is powered for the first time, the electronic device determines that the main area controller is initialized; if the main area controller is always in a power supply state after being electrified for the first time, the electronic equipment judges that the main area controller is non-initialized.

Illustratively, when the primary zone controller is first powered on after the vehicle is manufactured, the electronic device determines that the primary zone controller is initialized.

And under the condition that the connection between the main area controller and the storage battery of the vehicle is not disconnected after the first power-on and the storage battery of the vehicle is not in a power-shortage state, the electronic equipment judges that the main area controller is not initialized.

As another possible implementation manner, if the main area controller resumes the power supply after the power supply is interrupted, the electronic device determines that the main area controller is initialized.

For example, when the battery of the vehicle is replaced and maintained, the electronic device determines that the main zone controller is initialized after the power supply of the vehicle is restored.

S302, if the main area controller is not initialized, the electronic device judges whether the first vehicle identification code stored in the main area controller is identical to the vehicle identification code.

And S303, under the condition that the main area controller is initialized, the electronic equipment determines the maximum value of the first mileage value and at least one second mileage value as an initial mileage value.

As a possible implementation, in the case that the main area controller is initialized, the electronic device determines a maximum value from the first mileage value and the at least one second mileage value, and determines the maximum value as the initial mileage value.

And S304, if the main area controller is not initialized, if the first vehicle identification code stored in the main area controller is different from the vehicle identification code of the vehicle, the electronic equipment determines the maximum value of the first mileage value and the at least one second mileage value as an initial mileage value.

In the actual application process, the electronic equipment updates the vehicle identification code of the vehicle according to the first vehicle identification code.

S305, the electronic equipment judges whether the first mileage value is smaller than a preset mileage value.

And S306, under the condition that the main area controller is non-initialized and the first vehicle identification code is the same as the vehicle identification code of the vehicle, responding to the modification operation of the user on the first mileage value, and if the first mileage value is smaller than a preset mileage value, determining the minimum value of the first mileage value and at least one second mileage value as an initial mileage value by the electronic equipment.

As one possible implementation manner, if the electronic device receives the modification operation of the first mileage value by the user, and if the main area controller is non-initialized and the first vehicle identification code is the same as the vehicle identification code of the vehicle, it is determined whether the first mileage value is smaller than the preset mileage value.

And under the condition that the first mileage value is smaller than the preset mileage value, the electronic equipment determines a minimum value from the first mileage value and at least one second mileage value, and determines the minimum value as an initial mileage value.

By way of example, the preset mileage value may be 256 km.

In the actual application process, under the condition that the main area controller is non-initialized and the first vehicle identification code is the same as the vehicle identification code of the vehicle, and the power gear of the vehicle is started, the speed signal of the vehicle is 0, the first mileage value is smaller than a preset mileage value, and if the user manually modifies and reduces the first mileage value, the electronic equipment determines the minimum value of the first mileage value and at least one second mileage value as an initial mileage value.

According to the technical scheme provided by the embodiment of the application, the initialization state of the main area controller is judged in advance, so that the maximum value of the first mileage value and at least one second mileage value can be determined as the initial mileage value when the main area controller is initialized; by judging in advance whether the first vehicle identification code stored in the main area controller is identical to the vehicle identification code of the vehicle in the case where the activation state of the main area controller is non-initialized, it is possible to determine the maximum value of the first mileage value and the at least one second mileage value as the initial mileage value in the case where the first vehicle identification code stored in the main area controller is not identical to the vehicle identification code; and determining whether the first mileage value is smaller than a preset mileage value or not in response to a user modification operation of the first mileage value when the activation state of the main area controller is non-initialized and the first vehicle identification code is the same as the vehicle identification code of the vehicle, and determining the minimum value of the first mileage value and at least one second mileage value as an initial mileage value when the first mileage value is smaller than the preset mileage value. In this way, a method of determining an initial mileage value from a first mileage value and at least one second mileage value is implemented by determining whether an initialization state of a main area controller, a first vehicle identification code stored in the main area controller is identical to a vehicle identification code of a vehicle, and determining whether the first mileage value is smaller than a preset mileage value.

In some embodiments, in order to implement updating of the mileage values in the main area controller and at least one redundant area controller, or in the vehicle machine of the vehicle, as shown in fig. 4, the method for updating the mileage values of the vehicle provided by the embodiment of the application further includes the following steps:

s401, the electronic equipment acquires the updated current mileage value.

And S402, after updating the current mileage value, the electronic equipment synchronizes the updated current mileage value to the main area controller and the at least one redundant area controller, or displays the updated current mileage value on the machine of the vehicle.

As one possible implementation manner, the electronic device sends an instruction for storing the updated current mileage value to the basic service layer of the main area controller and the at least one redundant area controller; correspondingly, at least one basic service layer acquires the storage instruction and stores the updated current mileage value into the storage layer.

The electronic device sends the updated current mileage value to an experience domain computer (experience domain computer, EDC) in an Application (APP) layer; correspondingly, the EDC receives the updated current mileage value and displays the updated current mileage value in the vehicle body of the vehicle.

As another possible implementation manner, if the difference between the updated current mileage value and the current mileage value before updating is greater than the preset difference, the electronic device sends an instruction for storing the updated current mileage value to the basic service layers of the main area controller and the at least one redundant area controller; correspondingly, at least one basic service layer acquires the storage instruction and stores the updated current mileage value into the storage layer.

The electronic device sends the updated current mileage value to an experience domain computer (experience domain computer, EDC) in the application layer; correspondingly, the EDC receives the updated current mileage value and displays the updated current mileage value in the vehicle body of the vehicle.

It should be noted that, after the storage instruction is acquired, the basic service layer may update the pre-update mileage value stored therein, without deleting the pre-update mileage value.

According to the technical scheme provided by the embodiment of the application, after the current mileage value is updated, the electronic equipment synchronizes the updated current mileage value to the main area controller and the at least one redundant area controller, or displays the updated current mileage value on the vehicle body of the vehicle. Thus, updating the mileage values of the main area controller and the at least one redundant controller can be achieved by storing the updated current mileage values in the main area controller and the at least one redundant controller.
