Detailed Description
The technical scheme of the invention is further elaborated by combining the drawings and the specific embodiments in the specification. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a software upgrading method provided for the embodiment of the present invention may be executed by a software upgrading apparatus provided in the embodiment of the present invention, where the software upgrading apparatus may be implemented in a software and/or hardware manner, and the software upgrading method includes the following steps:
step S101: when the first vehicle determines that the software is to be updated, sending a software detection request message to the second vehicle through the V2V communication connection; the software detection request message carries the version information to be upgraded of the software to be updated;
here, the first vehicle determines that the software needs to be updated, may receive a software upgrade message sent by the cloud server to the vehicle, may send a software version query request to the cloud server to know that the software needs to be updated, and may send a software version query request to the second vehicle through the V2V communication connection to detect whether the software needs to be updated. The first vehicle and the cloud server can communicate based on 3G, 4G, 5G, WiFi and other wireless modes.
As can be appreciated, the Internet of vehicles enables real-time information interaction between vehicles by utilizing wireless cellular communication technology. With the development of wireless multimedia services, cellular networks centered on base stations have obvious limitations in terms of high data rate and support of proximity services, and in order to meet the index requirements of low delay and high reliability required by communication between vehicles in Vehicle networking communication, V2V (Vehicle to Vehicle) communication can be realized by the current Vehicle networking communication mode. In particular, V2V communication generally employs the prior art D2D (Device-to-Device) communication technique, and the use of V2V communication may reduce the latency of transmission compared to the transmission of communication information by a vehicle through a network Device. In the V2V communication method, each vehicle is used as an independent individual, and two-to-two communication is actually performed between the vehicles. The V2V communication connection includes, but is not limited to, a wireless local area network connection, a bluetooth connection, and the like.
Here, the sending of the software detection request message from the first vehicle to the second vehicle through the V2V communication connection may be sending of a software detection request message carrying information of a to-be-upgraded version of the to-be-upgraded software to the second vehicle when the first vehicle is in V2V communication connection with the second vehicle through a wireless lan connection, a bluetooth connection, or the like. The information of the version to be upgraded of the software to be updated is higher than the existing version information of the software to be updated of the first vehicle, and the software detection request message is used for requesting to detect whether the second vehicle has a software upgrade package corresponding to the version to be upgraded of the software to be updated.
In an embodiment, when the first vehicle determines that the software is to be updated, before sending the software detection request message to the second vehicle through the V2V communication connection, the method may further include: receiving a software upgrading message sent by a cloud server, and determining software to be updated and version information to be upgraded of the software to be updated according to the software upgrading message.
Specifically, when vehicle-mounted software such as a vehicle-mounted application or a vehicle-mounted control system with a latest version is updated, the cloud server may send a software upgrading message to the first vehicle, where the software upgrading message at least includes information of software to be updated, information of a version to be upgraded of the software to be updated, information of an applicable vehicle type, and an MD5 check value of a software upgrading package corresponding to the version to be upgraded of the software to be updated. And in combination with the software information which needs to be updated, the first vehicle can determine the software to be updated and the version information to be updated of the software to be updated according to the software updating message.
It can be understood that due to the needs of technical updating or repairing bugs existing in the software, the software needs to be updated in time to ensure the normal work of the vehicle, and therefore, the cloud server can send software upgrading messages to the vehicle at regular time or irregular time. It should be noted that, the software to be updated is updated, which may also be referred to as updating the software of the vehicle or upgrading the vehicle.
In an embodiment, when the first vehicle determines that the software is to be updated, before sending the software detection request message to the second vehicle through the V2V communication connection, the method may further include: the first vehicle sends a software version inquiry request message to the second vehicle through a V2V communication connection; the software version query request message carries information of software to be queried; the first vehicle receives a software version query response message returned by the second vehicle through the V2V communication connection, and determines the software to be queried as the software to be updated when the version of the software to be queried of the second vehicle is higher than the version of the software to be queried of the first vehicle according to the software version query response message.
Specifically, the first vehicle sends a software version query request message to the second vehicle through a V2V communication connection, so that the second vehicle queries the version of the software to be queried installed on the second vehicle according to the software information to be queried carried in the software version query request message, thereby obtaining the version of the software to be queried of the second vehicle. The determining, by the first vehicle, that the version of the software to be queried of the second vehicle is higher than the version of the software to be queried of the first vehicle may mean that the version of the software to be queried of the second vehicle is newer than the version of the software to be queried of the first vehicle, for example, if the version of the software to be queried of the first vehicle is V5.0, and the version of the software to be queried of the second vehicle is V6.0, then the version of the software to be queried of the second vehicle is higher than the version of the software to be queried of the first vehicle. And when the first vehicle determines that the version of the software to be queried of the second vehicle is higher than that of the software to be queried of the first vehicle according to the software version query response message, determining the software to be queried as the software to be updated, namely, updating the software to be queried. In this way, the first vehicle queries the software version of the second vehicle through the V2V communication connection, and determines the software to be queried as the software to be updated when it is determined that the version of the software to be queried of the second vehicle is higher than the version of the software to be queried of the first vehicle, which is simple and intelligent to operate.
Here, the V2V communication connection includes, but is not limited to, a wireless local area network connection, a bluetooth connection, and the like. Since the bluetooth connection is a one-to-one connection, i.e., the vehicle can only establish one bluetooth connection at the same time. Therefore, when a first vehicle establishes a V2V communication connection with a second vehicle through a bluetooth connection, before the bluetooth connection is established with the second vehicle, if the first vehicle detects that the bluetooth connection is established with a mobile terminal, the bluetooth connection with the mobile terminal is disconnected to ensure that the bluetooth connection can be established with the second vehicle. It should be noted that, as long as the first vehicle detects that the bluetooth connection has been established with the terminal other than the second vehicle, the established bluetooth connection needs to be disconnected. In this way, the first vehicle can ensure that the bluetooth connection can be established with the second vehicle by disconnecting the established bluetooth connection in time, so as to ensure that the V2V communication connection is established with the second vehicle in time.
Step S102: the first vehicle receives a software detection response message returned by the second vehicle through V2V communication connection, and sends a software downloading request message carrying information of the version to be upgraded of the software to be upgraded to the second vehicle when the second vehicle is determined to have a software upgrading package corresponding to the version to be upgraded of the software to be upgraded according to the software detection response message;
specifically, when the first vehicle determines that the second vehicle has a software upgrade package corresponding to the to-be-upgraded version of the to-be-upgraded software according to a software detection response message returned by the second vehicle through the V2V communication connection, the first vehicle sends a software download request message carrying information of the to-be-upgraded version of the to-be-upgraded software to the second vehicle.
Here, the receiving, by the first vehicle, the software detection response message returned by the second vehicle through the V2V communication connection may refer to that after receiving the software detection request message, which is sent by the first vehicle and carries information of the to-be-upgraded version of the to-be-upgraded software, the second vehicle analyzes the software detection request message, then detects whether the second vehicle has a software upgrade package corresponding to the to-be-upgraded version of the to-be-upgraded software according to the to-be-upgraded version of the to-be-upgraded software carried by the software detection request message, generates the software detection response message according to a detection result, and sends the software detection response message to the first vehicle through the V2V communication connection, where the first vehicle receives the software detection response message returned by the second vehicle through the V2V communication connection. The software detection response message is used for representing whether the second vehicle has a software upgrading package corresponding to the to-be-upgraded version of the to-be-upgraded software of the first vehicle. When the first vehicle determines that the second vehicle has the software upgrading package corresponding to the version to be upgraded of the software to be upgraded according to the software detection response message, sending a software downloading request message carrying information of the version to be upgraded of the software to be updated to the second vehicle, may refer to that when the first vehicle determines that the second vehicle has the software upgrade package corresponding to the to-be-upgraded version of the to-be-upgraded software according to the received software detection response message returned by the second vehicle through the V2V communication connection, sending a software downloading request message carrying information of the version to be upgraded of the software to be updated to the second vehicle, the software downloading request message is used for requesting the second vehicle to allow the first vehicle to download the software upgrading package corresponding to the to-be-upgraded version of the to-be-upgraded software through the V2V communication connection.
Step S103: and the first vehicle receives a software upgrading package corresponding to the to-be-upgraded version of the to-be-upgraded software sent by the second vehicle through the V2V communication connection.
Specifically, the first vehicle receives a software upgrading package corresponding to the to-be-upgraded version of the to-be-upgraded software sent by the second vehicle through the V2V communication connection, so as to perform software upgrading according to the software upgrading package corresponding to the to-be-upgraded version of the to-be-upgraded software.
In summary, in the software upgrading method provided in the above embodiment, when a first vehicle determines that software is to be updated, a software detection request message is sent to a second vehicle through a V2V communication connection, where the software detection request message carries information of a version to be upgraded of the software to be updated, then a software detection response message returned by the second vehicle through the V2V communication connection is received, and when it is determined that the second vehicle has a software upgrading package corresponding to the version to be upgraded of the software to be updated according to the software detection response message, a software downloading request message carrying the information of the version to be upgraded of the software to be updated is sent to the second vehicle, and the software upgrading package corresponding to the version to be upgraded of the software to be updated and sent by the second vehicle through the V2V communication connection is received. Therefore, the software to be updated of the vehicle is upgraded through the V2V communication connection between the vehicle and the vehicle, the software to be updated does not need to be downloaded from the cloud server, the burden of the cloud server is reduced, the network condition, the vehicle flow and the like are not limited, the operation is convenient and fast, the reliability is high, and the cost is low.
In one embodiment, the software upgrading method further includes: and the first vehicle carries out MD5 verification on the software upgrading package, and if the verification is passed, the software to be updated is upgraded by using the software upgrading package.
It should be noted that, the fifth version of the Message Digest Algorithm (MD5, Message Digest Algorithm5) is a Message Digest Algorithm, which can generate a special string from a string or a file according to a certain rule, and the MD5 value corresponding to a file is fixed, and when the content of the file changes, the MD5 value may also be different. Therefore, MD5 values are often used in practical applications to verify that a piece of data has been tampered with. For example, a sender of data generates an MD5 value according to original data, then transmits the original data together with an MD5 value thereof to a receiver, after receiving the original data, the receiver first generates an MD5 value by using an MD5 algorithm on the original data, then compares the MD5 value with an MD5 value sent by the sender, and if the MD5 value is consistent with the MD5 value, the original data is considered to be unmodified, otherwise, the original data is modified.
Here, after the first vehicle receives a software upgrade package corresponding to the version to be upgraded of the software to be updated, which is sent by the second vehicle through the V2V communication connection, MD5 verification is performed on the software upgrade package, and if the verification passes, the software to be updated is upgraded by using the software upgrade package. It should be noted that, when the second vehicle sends the software upgrade package corresponding to the version to be upgraded of the software to be updated to the first vehicle, the MD5 check value corresponding to the software upgrade package corresponding to the version to be upgraded of the software to be updated may be sent to the first vehicle, so that the first vehicle performs MD5 check on the software upgrade package according to the MD5 value. In addition, the MD5 value may also be sent by the cloud server to the first vehicle via a software upgrade message. Therefore, the software to be updated is updated by using the software upgrading package after the received software upgrading package is verified by the MD5, the software upgrading package is ensured not to be modified, and the safety of the vehicle is improved.
In an embodiment, the receiving, by the first vehicle, a software upgrade package corresponding to the to-be-upgraded version of the to-be-updated software sent by the second vehicle through a V2V communication connection includes: and the first vehicle displays the receiving progress of the software upgrading package corresponding to the version to be upgraded of the software to be upgraded in real time.
Here, when the first vehicle receives the software upgrade package corresponding to the to-be-upgraded version of the to-be-upgraded software sent by the second vehicle through the V2V communication connection, the receiving progress of the software upgrade package corresponding to the to-be-upgraded version of the to-be-upgraded software is displayed in real time, for example, the receiving progress of the software upgrade package corresponding to the to-be-upgraded version of the to-be-upgraded software is displayed in real time on a vehicle-mounted device screen, or a prompt sound is sent out through a vehicle-mounted sound device or the like when the receiving is completed. Therefore, the receiving progress of the software upgrading package corresponding to the version to be upgraded of the software to be upgraded is displayed in real time, so that a user can know the receiving condition of the software upgrading package in time and know the downloading progress of the software upgrading package, and the use experience of the user is improved.
Referring to fig. 2, a software upgrading method provided for the embodiment of the present invention may be executed by a software upgrading apparatus provided in the embodiment of the present invention, where the software upgrading apparatus may be implemented in a software and/or hardware manner, and the software upgrading method includes the following steps:
step S201: a second vehicle receives a software detection request message sent by a first vehicle through V2V communication connection, wherein the software detection request message carries information of a to-be-upgraded version of the to-be-upgraded software;
here, when the second vehicle and the first vehicle are in V2V communication connection, the second vehicle receives a software detection request message sent by the first vehicle to inquire whether the second vehicle has a software upgrade package corresponding to a to-be-upgraded version of software to be updated. Specifically, after receiving the software detection request message sent by the first vehicle, the second vehicle analyzes the software detection request message, and detects whether a software upgrade package corresponding to the version to be upgraded of the software to be upgraded is stored in the vehicle according to the version to be upgraded of the software to be upgraded carried in the software detection request message.
Here, the receiving of the software detection request message by the second vehicle, which is sent by the first vehicle through a V2V communication connection, may be receiving a software detection request message, which is sent by the first vehicle and carries information of a to-be-upgraded version of the to-be-upgraded software, after the second vehicle establishes a V2V communication connection with the first vehicle through a wireless local area network connection, a bluetooth connection, or the like, where the software detection request message is used to request to detect whether the second vehicle has a software upgrade package corresponding to the to-be-upgraded version of the to-be-upgraded software.
