Example 1
In this embodiment, there is provided a vehicle-mounted system upgrading method of a vehicle-mounted wireless routing device operating on a vehicle supporting Wifi Direct, and fig. 1 is a flowchart of the vehicle-mounted system upgrading method according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:
step S102, determining the highest version of the vehicle-mounted application system of the vehicle-mounted routing equipment included in the vehicle-mounted routing equipment group, wherein the vehicle-mounted routing equipment included in the vehicle-mounted routing equipment group is in direct communication through Wifi;
step S104, the vehicle-mounted application systems of the vehicle-mounted routing equipment included in the vehicle-mounted routing equipment group are all upgraded to the highest version.

Alternatively, the upgrading of the vehicle-mounted application systems of the vehicle-mounted routing devices in the vehicle-mounted routing device group to the highest version can be achieved in various manners. For example, one of the remaining vehicles (e.g., vehicle B) may be upgraded with the vehicle having the highest version (e.g., vehicle a), then two vehicles (vehicle a and vehicle B) may each be upgraded with the remaining vehicles, and so on, until all vehicles are upgraded to the highest version. For another example, in the case where the system version corresponding to one predetermined vehicle determined from the in-vehicle routing device group is not the highest version, the system version corresponding to the predetermined vehicle may be upgraded to the highest version; updating an upgradeable list corresponding to the scheduled vehicle, wherein the upgradeable list corresponding to the scheduled vehicle comprises information of vehicles to be upgraded, and the vehicles to be upgraded are vehicles of which the system version of a vehicle-mounted application system in the vehicle-mounted routing equipment group is lower than the system version corresponding to the scheduled vehicle; and upgrading the system version corresponding to the vehicle to be upgraded in the updated upgradeable list corresponding to the scheduled vehicle to the highest version. For another example, in the case where the system version corresponding to the predetermined vehicle is the highest version, an upgradeable list corresponding to the predetermined vehicle (similar to the previous upgradeable list) may be determined, and the system version corresponding to the vehicle to be upgraded in the upgradeable list corresponding to the predetermined vehicle is upgraded to the highest version.
Other vehicles except the scheduled vehicle in the vehicle-mounted routing equipment group can also have corresponding upgradeable lists, the information of the vehicle to be upgraded contained in the upgradeable list corresponding to the appointed vehicle is provided, and the vehicle to be upgraded is a vehicle of which the system version of the vehicle-mounted application system in the vehicle-mounted routing equipment group is lower than the system version corresponding to the appointed vehicle. The predetermined vehicle may be a Group Owner (or Group Owner, alternatively referred to as a Group moderator) in the Group, which may be determined by negotiation.
Optionally, before upgrading the system version corresponding to the predetermined vehicle to the highest version, the vehicle with upgrade in the corresponding upgradeable list may be first upgraded to the system version corresponding to the predetermined vehicle, and then the system version of the specified vehicle may be upgraded to the highest version; after the upgradeable list corresponding to the scheduled vehicle is updated to the upgradeable list corresponding to the highest version, the vehicle-mounted application system of the vehicle to be upgraded in the upgradeable list after updating is updated to the highest version. By means of the segmented upgrading mode, the problem of upgrading interruption caused by too long upgrading time due to too large version interval can be avoided.
Optionally, in the case that the number of vehicles to be upgraded is at least two, the system versions corresponding to the at least two vehicles to be upgraded may be upgraded to the highest version according to a preset policy according to version information of the system versions corresponding to the vehicles to be upgraded in the upgradeable list, where the preset policy may be to upgrade the system version with the smallest version interval of the system versions corresponding to the predetermined vehicles preferentially (may ensure the success rate of upgrade), upgrade the system version with the largest version interval of the system versions corresponding to the predetermined vehicles preferentially (may ensure that the system versions of the vehicle-mounted application systems of the respective vehicles in the group are not too low), or upgrade the system version of the vehicle with the earlier connection time with the predetermined vehicle preferentially.
Based on the foregoing embodiments and the preferred embodiments, in order to describe the whole flow interaction of the solution, in this preferred embodiment, a method for upgrading an on-vehicle system is provided, and the following description is made on the method and a device and a system capable of implementing the method.
In the vehicle-mounted system, for the application with higher update frequency requirement, the navigation system can be conveniently updated, and even if the after-sales point cannot be reached or wireless connection cannot be carried out, the updating can be carried out, so that the whole vehicle-mounted system can be greatly influenced.
The vehicle-mounted system upgrading method provided by the preferred embodiment of the invention enables the vehicle-mounted system to be upgraded more conveniently. Through the Wifi Direct vehicle-mounted mobile terminal, each mobile vehicle can automatically find and networking, meanwhile, whether the vehicle in the networking has the latest navigation system or not is judged, if the latest navigation system exists in the networking or is a system newer than the vehicle, an update request is carried out, and a target system is downloaded to the vehicle-mounted system through the Wifi Direct and updated. The final navigation system is perfected and updated, after-sales point maintenance is not needed, or a user manually performs upgrading, and the perfection and upgrading of the target system can be automatically completed only through Wifi Direct networking. The method for upgrading the vehicle-mounted system is described below with reference to a specific system.
The vehicle-mounted system upgrading method provided in the preferred embodiment can be applied to a vehicle-mounted application automatic updating system based on Wifi Direct (Direct connection), and the system mainly comprises the following steps: the vehicle-mounted wireless routing device supports Wifi Direct; a vehicle-mounted device supporting Wifi or an external navigator device supporting Wifi. The respective devices are described below.
The vehicle-mounted wireless routing device supporting Wifi Direct comprises: the system comprises a Wifi Direct automatic discovery networking subsystem, a system comparison discovery subsystem, a system updating strategy subsystem, a latest system storage subsystem, a wireless routing internet surfing subsystem and a vehicle-mounted device information exchange subsystem.
The Wifi Direct automatic discovery networking subsystem is responsible for completing automatic networking of Wifi Direct according to a discovery networking mechanism of Wifi Direct protocol when the same type of vehicles appear around. Because the coverage area of the Wifi Direct is larger (two football fields can be reached to be larger), more devices can appear in the coverage area, so that the networking subsystem is automatically found, meanwhile, judgment is carried out according to the signal intensity of the found Wifi Direct terminal, and the networking can be carried out according with enough signal intensity. In the networking process, due to the discontinuity of version upgrading, only vehicles which are mutually upgraded with the Group Owner can be added into the Group, and 5 vehicles can be set as an upper limit in the same networking.
The system contrast discovery subsystem is responsible for Wifi Direct slave devices (devices except the Group Owner or called vehicles) in the networking, transmitting the version numbers of own application systems to Wifi Direct master devices (Group Owner) in the networking, and the master devices contrast the version numbers transmitted by the master devices and other slave devices and record the information of the slave devices.
And the system updating strategy subsystem is responsible for updating the updating strategy. Since the system versions of the vehicles in the same network (similar to the above-mentioned vehicle-mounted routing equipment group) are not the same, and the simultaneous upgrade of the subsystems to the latest system consumes more information, an upgrade policy update is required, and an upgrade from a low level to a high level (or an upgrade from a small version interval to a large version interval) is possible. When upgrading, the upgrading requests of other vehicles are ignored. After the primary upgrading is finished, the system updating strategy subsystem updates the strategy again, updates the upgrading list of each vehicle, and then continues to upgrade.
The two versions in the networking are simplest, and the two Wifi Direct devices negotiate to upgrade to the system with the latest version number. When three versions are different, firstly determining the Group Owner, preferentially upgrading the lowest version to the Group Owner, upgrading two vehicle systems to the same version, then upgrading the rest low version again, and finally upgrading the three vehicles to the highest version together. When the system update is interrupted, two latest different versions need to be saved, if the different versions are found after networking is found again, the former one is deleted, and the one with the smaller completion percentage can be deleted preferentially.
And the wireless routing internet surfing subsystem is responsible for updating the system when the Wifi Direct fails to complete the updating and upgrading of the system, and is configured to update the wireless internet surfing version when the internet surfing condition exists, and the updating is downloaded through wireless internet surfing. The default configuration may be Wifi Direct priority.
After the latest system is acquired, the latest system storage subsystem stores the latest version in the vehicle-mounted wireless routing device.
And the vehicle-mounted device information exchange subsystem is responsible for reading the version number of the vehicle-mounted navigation system after being successfully connected with the vehicle-mounted device Wifi. After the latest system is acquired by the latest system storage subsystem, the navigation system in the vehicle-mounted device is updated by the vehicle-mounted device information exchange subsystem through the Wifi in an online updating mode.
The vehicle-mounted device supporting Wifi includes: wifi module and navigation system.
The vehicle-mounted system upgrading method provided in the preferred embodiment describes a vehicle-mounted system automatic upgrading implementation mode based on a Wifi Direct technology and is exemplified by three vehicles (a vehicle, B vehicle and C vehicle). Before the vehicle-mounted routing equipment is used, the vehicle-mounted routing equipment is started, the Wifi of the vehicle-mounted equipment is started, the vehicle-mounted routing equipment is connected with the vehicle-mounted routing equipment, and the default settings of the vehicle-mounted routing equipment of the three vehicles are updated in the Wifi Direct discovery networking preferentially. The vehicle-mounted system upgrading method specifically comprises the following steps:
The first step: the Wifi of the vehicle-mounted equipment is opened and is connected with the vehicle-mounted routing equipment, and the version information of the application system in the vehicle-mounted routing equipment or the current vehicle-mounted equipment is used. In the preferred embodiment, the application system version of the a car is the B04 version, the application system version of the B car is the B05 version, and the application system version of the C car is the B01 version;
and a second step of: the Wifi Direct function of the vehicle-mounted routing equipment is enabled, an automatic discovery and networking function is enabled, three A, B, C vehicles automatically discover and carry out Wifi Direct networking on the basis of Wifi Direct technology, in the networking process, an upgradeable list of A vehicles comprises a B01 version of C vehicles, and an upgradeable list of B vehicles comprises a B04 version of A vehicles and a B01 version of C vehicles. The upgradeable list illustrates that B01 can be allowed to rise from A to B04, and B vehicle can be allowed to upgrade from B04 or B01 to B05;
and a third step of: A. b, C the three-vehicle on-vehicle routing devices exchange versions of the on-vehicle application systems with each other, and generate an update policy according to a system update policy subsystem in the on-vehicle routing device, and A, B, C may become a Group Owner because the Group Owner is determined by negotiation.
When the A car is a Group Owner, the A car is provided with an upgradeable list, meanwhile, the upgradeable lists of the B car and the C car are also known, the upgrade from low level to high level is triggered preferentially, the C car is upgraded preferentially to the A car, the upgrade is successful, and the upgradeable list of the A car is updated to the C car; meanwhile, upgrading the vehicle A to the vehicle B, wherein the upgrading is successful, and updating an upgradeable list of the vehicle B to the vehicle A; and finally, upgrading the C car to the A car, wherein the upgrading is successful, and updating the upgradeable list of the A car to the C car. Finally, all three vehicles reach the highest version (B05);
When the B car is a Group Owner, upgrading the C car and the B car, wherein the C is updated to B05, the upgrading is successful, and an upgradeable list of the B car is updated to the C car; meanwhile, upgrading the B car and the A car, upgrading the A car to the B05, and updating an upgradeable list of the B car to the A car; finally, the three vehicles reach the highest version (B05) (in the case that the priority strategy is that the version interval is from small to large, the A vehicle is upgraded to B05, and then the C vehicle is upgraded to B05);
when the C car is a Group Owner, upgrading the C car and the B car, lifting the C car to B05, simultaneously updating an upgradeable list of the B car to the C car, then upgrading the C car and the A car again, lifting the A car to B05, and simultaneously updating an upgradeable list of the A car. Eventually the three cars reach the highest version (B05).
Fourth step: after the version upgrading of each vehicle is finished, the latest system storage subsystem temporarily stores the latest system application version in the vehicle-mounted wireless route, and the latest system storage subsystem also comprises the current version of the vehicle.
Fifth step: the vehicle-mounted wireless route is connected with the vehicle-mounted device through Wifi, and the latest system application which is successfully downloaded is transmitted to a special reserved area in the vehicle-mounted device through the vehicle-mounted device information exchange subsystem;
sixth step: the special reserved area of the vehicle-mounted device has the latest system application version, and the vehicle-mounted device is restarted to load the latest system application, so that the version upgrading process of the whole system application is completed.
The method for upgrading the vehicle-mounted system in the embodiment of the invention is further described below.
Fig. 2 is a flow chart of an on-board system upgrade method according to a preferred embodiment of the present invention, as shown in fig. 2, the method comprising the steps of:
step S202, a vehicle-mounted wireless routing system is connected with a vehicle-mounted device through Wifi;
step S204, the vehicle-mounted information exchange subsystem acquires information from the vehicle-mounted device through Wifi connection, wherein the information is mainly version information of system applications needing to be upgraded, such as version numbers of navigation systems;
step S206, the vehicle-mounted wireless routing system adopts a Wifi Direct technology to send Wifi Direct broadcast information to the periphery so as to be discovered by other vehicle-mounted wireless routes and networking;
step S208, after the vehicle-mounted wireless route is negotiated through a Wifi Direct technology, and the distance of the relative position is roughly judged according to the received returned Wifi signal intensity, the vehicles are automatically networked, the maximum number of the vehicles is not more than 5, and in the Service Discovery stage, the networked vehicles are compared with the respective upgradeable lists, and only the vehicles which can be mutually upgraded are allowed to be added into the group;
step S210, after automatic networking is successful, when the Group Owner of the Group meets the condition (for example, the Group meets 5 or no new member is added in 1 minute), the Group Owner is responsible for starting the upgrading process;
Step S212, the system updating strategy subsystem performs strategy assignment of system updating, the Group Owner obtains information of other Group clients (Group members) in the current network from the comparison discovery subsystem, and judges whether the supporting capability of the current Group Client connection is met or not, if the space to be updated is met, if the bandwidth is enough, other upgradeable vehicles are started to be upgraded at the same time;
step S214, after the Group Owner and the Group Client acquire the application instruction, wifi Direct transmission is carried out until version upgrade is successfully carried out;
step S216, on the target Group client vehicle-mounted wireless routing system, the latest system storage subsystem stores a new version;
step S218, on the target Group Client vehicle-mounted wireless routing system, the vehicle-mounted information exchange subsystem issues an upgrade version command, and the vehicle-mounted wireless routing system downloads the latest application system version to a system upgrade special reserved area of the vehicle-mounted device to wait for upgrade actions of a user;
in step S220, when the Group Owner exits the Group, the Group needs to re-perform the networking process and determine a new Group Owner, and after the determination, the upgrading process is continued.
In the following, by way of a specific example, it is described how two vehicles are connected by Wifi Direct in the preferred embodiment, and automatically networking.
Fig. 3 is a schematic diagram of a two WiFi Direct connection interaction process according to a preferred embodiment of the present invention, as shown in fig. 3, a default state of A, B two vehicles with WiFi Direct functions is in a search to the surroundings, to see if there is a connectable WiFi Direct terminal (or device), periodically send a Probe request message to other vehicles, and enter a list state after sending three requests. And when the B vehicle is in a Listen interception state, receiving a Probe request message sent by the A vehicle, and returning a Probe response message to indicate that the B vehicle is in a connectable state, and waiting for further reply of the A vehicle. The a car will then send Service Discovery Query a message, in this example, automatically upgrade such a service of the on-board system, while the a car sends its own upgradeable list information in Service Discovery Query a message. After receiving the message, the vehicle B analyzes the vehicle A upgradeable list, analyzes the analyzed upgradeable list (as shown in fig. 4), and replies Service Discovery Response a successful message if the mutual upgrade condition is met. If the mutual upgrade condition is not met, a Service Discovery Response failure message is replied and the entire process is terminated. The vehicle a then issues a GO (Group Owner) Negotiation request request message to make a networking request. And after the B car receives the request message, analyzing the Wifi signal strength of the A car, and replying Go Negotiation response (success) message after meeting the Wifi signal strength condition. And A, replying GO Negotiation confirmation information, and finally determining the roles of GO and Client after successful networking. After successful networking, GO sends Beacon message, client carries out 4 times of handshake message, and finally establishes data transmission connection for data service transmission.
The triggering of the upgrading process is determined by the GO, and if the GO does not receive the request of joining the group within 1 minute, the current group is considered to be stable, and the upgrading process is started.
