Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
An upgrade data transmission method and apparatus according to embodiments of the present application will be described in detail with reference to the accompanying drawings.
Fig. 1 is a diagram of an upgrade data transmission method according to an embodiment of the present application, where, as shown in fig. 1, the method includes:
s101, acquiring network parameters of a current vehicle, and determining the network state of the current vehicle based on the network parameters;
s102, if the network state meets the target state, acquiring at least one upgrade data from an upgrade server;
S103, determining target vehicles from adjacent vehicles, and determining target upgrading data corresponding to each target vehicle from the acquired at least one upgrading data;
s104, determining a target transfer path corresponding to each target vehicle, and transmitting target upgrading data corresponding to the target vehicle based on the target transfer path corresponding to the target vehicle.
Specifically, the upgrade data transmission method provided by the present example is applied to vehicles including vehicles with automatic driving or intelligent driving (including passenger function vehicles (e.g., sedans, buses, wagons, golf carts, etc.), cargo function vehicles (e.g., regular trucks, vans, dump trucks, closed trucks, tank trucks, flatcars, container cars, dump trucks, special structure trucks), special vehicles (e.g., logistics distribution vehicles, automated guided transport vehicles AGVs, patrol cars, cranes, excavators, bulldozers, forklift trucks, road loaders, off-road engineering vehicles, armored vehicles, sewage treatment vehicles, sanitation vehicles, dust trucks, floor washing vehicles, sprinkler vehicles, sweeping robots, meal delivery robots, shopping guide robots, mowers, golf carts, etc.), recreational vehicles (e.g., recreational vehicles, amusement park automatic driving devices, balance cars, etc.), rescue vehicles (e.g., fire trucks, ambulances, electric power repair vehicles, engineering emergency vehicles, etc.), and the like).
In some examples, the current vehicle obtains network parameters of the vehicle through a network detection module provided by itself, including but not limited to: network bandwidth, network delay, etc.; network bandwidth refers to the amount of data that can be transmitted per unit time (typically 1 second). Network latency refers to the round-trip time of a data packet from the current vehicle to the upgrade server and then back from the upgrade server to the current vehicle. In brief, network latency is the network response time between a visitor to a visited.
With the above example in mind, the network status of the vehicle includes, but is not limited to: after acquiring network parameters, determining the network state of the current vehicle based on the network parameters, specifically, presetting a target network bandwidth and a target network delay by related personnel, comparing the acquired network bandwidth of the current vehicle with the target network bandwidth, and comparing the network delay with the target network delay, wherein if the network bandwidth is not lower than the target network bandwidth and the network delay is not lower than the target network delay, the network state of the current vehicle is in a good state; if the network bandwidth is lower than the target network bandwidth or the network delay is lower than the target network delay, the current network state of the vehicle is in a non-good state.
In some examples, when the network state meets the target state, at least one upgrade data is obtained from the upgrade server, where the target state is a good state, that is, when the network state of the current vehicle is a good state, at least one upgrade data can be obtained from the upgrade server, so that the situations that when the network of the current vehicle is not good, a connection line with the upgrade server is unstable, packet loss occurs, delay increases, even interruption occurs when serious, and repeated attempt to obtain and system resources are wasted are avoided.
With the above example in mind, it can be appreciated that the current vehicle is able to obtain at least one upgrade data from an upgrade server; in some examples, when the current vehicle obtains at least two upgrade data from the upgrade server, the at least two upgrade data correspond to different vehicle systems; for example, the current vehicle acquires A, B two upgrade data from an upgrade server, wherein the upgrade data A is upgrade data corresponding to a cabin system, and the upgrade data B is upgrade data corresponding to an audio-visual system and the like; in some examples, when the current vehicle obtains at least two upgrade data from the upgrade server, the at least two upgrade data correspond to different versions of the same vehicle system; for another example, the current vehicle obtains A, B two upgrade data from the upgrade server, where the upgrade data a is one version of upgrade data corresponding to the cabin system, and the upgrade data B is another version of upgrade data corresponding to the cabin system.
In some examples, the current vehicle obtains at least one upgrade data from the upgrade server, then adjusts itself to a distribution mode that characterizes itself as currently having upgrade data, and is capable of transmitting the upgrade data to other vehicles.
In some examples, after the current vehicle obtains at least one upgrade data from the upgrade server, a target vehicle is determined from the neighboring vehicles, and target upgrade data corresponding to each target vehicle is determined from the obtained at least one upgrade data, so as to determine corresponding target upgrade data for each target vehicle. Specifically, for example, the current vehicle acquires N upgrade data from the upgrade server, and the current vehicle determines the first target vehicle and the second target vehicle, so that the current vehicle determines target upgrade data corresponding to the first target vehicle from the N upgrade data, and determines target upgrade data corresponding to the second target vehicle, thereby avoiding the problem that data transmission pressure is overlarge because all the acquired upgrade data are sent to the target vehicle, and simultaneously avoiding the problem that invalid upgrade data for the target vehicle are transmitted to the target vehicle, resulting in invalid transmission, and improving the efficiency and practicability of the transmission of the target upgrade data.
In some examples, a target transfer path corresponding to each target vehicle is determined and target upgrade data corresponding to the target vehicle is transmitted based on the target transfer path corresponding to the target vehicle. The target transmission link includes a transmission path and a transmission method, where the transmission method includes but is not limited to: at least one of WiFi communication transmission, bluetooth communication transmission, 3G-5G data communication transmission, NFC near field communication transmission, infrared communication transmission and zigbee communication transmission is realized by determining the target transmission path between each target vehicle and the current vehicle, so that the situations of too slow data transmission speed, data transmission blockage, data transmission interruption and the like caused by directly transmitting target upgrading data to the target vehicles are avoided.
According to the technical scheme provided by the embodiment of the application, the network parameters of the current vehicle are obtained, and the network state of the current vehicle is determined based on the network parameters; if the network state meets the target state, acquiring at least one upgrade data from an upgrade server; the method comprises the steps of determining target vehicles from adjacent vehicles, determining target upgrading data corresponding to each target vehicle from at least one obtained upgrading data, realizing the subsequent transmission of the target upgrading data to the corresponding target vehicle only, further avoiding the problem that the data transmission pressure is overlarge because all obtained upgrading data are sent to the target vehicles, simultaneously avoiding the problem that invalid upgrading data are transmitted to the target vehicles and invalid transmission is caused, improving the efficiency and practicability of the transmission of the target upgrading data, determining a target transmission path corresponding to each target vehicle, and transmitting the target upgrading data corresponding to each target vehicle based on the target transmission path corresponding to the target vehicle.

s202, determining a system state of each adjacent vehicle, and determining a target vehicle according to the system state of each adjacent vehicle, wherein the system state is used for representing the current upgrading requirement of the adjacent vehicle.
Specifically, a position sensor is arranged on a current vehicle, the position sensor is a satellite-based positioning system, a position parameter of the current vehicle is determined by receiving signals transmitted by satellites, then a vehicle adjacent to the current vehicle is determined based on the position parameter of the current vehicle and the position parameters of other vehicles, and the adjacent vehicle is used as an adjacent vehicle; in some examples, the current vehicle may enable positioning by wireless signals and determine neighboring vehicles; in some examples, the current vehicle may also be positioned by capturing images with a camera and determining neighboring vehicles.
It can be appreciated that in some examples, after the position parameters of other vehicles are obtained and the adjacent vehicles are determined, classification verification is required to be performed on the adjacent vehicles, and after the classification verification of the adjacent vehicles is passed, the adjacent vehicles are used as the adjacent vehicles; such classification verification includes, but is not limited to: the brand classification verification and the model classification verification are taken as examples, the brand classification verification is carried out on each adjacent vehicle after the adjacent vehicle is determined by the current vehicle, the adjacent vehicle is taken as the adjacent vehicle after the brand classification verification passes (in some examples, when the adjacent vehicle and the current vehicle are in the same brand, the brand classification verification passes), and if the brand classification verification fails (in some examples, when the adjacent vehicle and the current vehicle are not in the same brand, the brand classification verification does not pass), the adjacent vehicle is not taken as the adjacent vehicle.
In some examples, after determining the neighboring vehicles adjacent to the current vehicle, determining a system state of each neighboring vehicle, wherein the system state is used for representing the current upgrading requirement of the neighboring vehicle, matching the system state with a preset target system state, and taking the neighboring vehicle as the target vehicle when the system state of the neighboring vehicle meets the target system state; if the system state of the adjacent vehicle does not meet the target system state, the adjacent vehicle is not taken as the target vehicle; specifically, for example, the preset target system state is a power-down state, and any system in the vehicle is in a state to be upgraded; the method comprises the steps that a current vehicle obtains a system state of each adjacent vehicle, and when the system state of each adjacent vehicle is in a power-down state and any system in the vehicle is in a state to be upgraded, the adjacent vehicle is taken as a target vehicle; otherwise, if the system state of the adjacent vehicle is not in the power-down state or the system in the vehicle is not in the state to be upgraded, the adjacent state is not taken as the target vehicle.
According to the technical scheme provided by the embodiment of the application, the position parameters of the current vehicle are determined according to the position sensor of the current vehicle, and the adjacent vehicles are determined based on the position parameters; the system state of each adjacent vehicle is determined, and the target vehicle is determined according to the system state of each adjacent vehicle, so that the effect of accurately determining the target vehicle is realized, and the problem of overload caused by taking all the adjacent vehicles as the target vehicle is avoided.
In some embodiments, as shown in fig. 3, determining target upgrade data corresponding to each target vehicle from the acquired at least one upgrade data includes:
s301, acquiring a system version of each target vehicle;
s302, determining the target upgrading data corresponding to each target vehicle according to the matching degree of the system version of each target vehicle and the system version corresponding to each upgrading data.
Specifically, the current vehicle acquires a system version of each target vehicle, wherein the acquired system version of the target vehicle includes a system version corresponding to any system used by the target vehicle, for example, the target vehicle includes a cabin system and an audio-visual system, and the acquiring the system version of the target vehicle includes acquiring the system version of the cabin system and the system version of the audio-visual system of the target vehicle.
In some examples, the target upgrade data corresponding to each target vehicle is determined according to the matching degree of the system version of each target vehicle and the system version corresponding to each upgrade data, wherein the current vehicle matches the system version of the target vehicle with the obtained upgrade data one by one, further determines the matching degree of the system version and the upgrade data, and takes the upgrade data as the target upgrade data when the matching degree of the system version and the upgrade data is higher than a threshold value.
In some examples, the current vehicle classifies the system version and the upgrade data, and then matches the same type of system version and upgrade data to determine the target upgrade data corresponding to the target vehicle, e.g., the system version of the target vehicle includes: the system version corresponding to the cabin system and the system version corresponding to the audio-video system are matched, and target upgrading data corresponding to the target vehicle is determined according to the matching degree; the system version corresponding to the video and audio system is matched with the upgrade data corresponding to the video and audio system, and the target upgrade data corresponding to the target vehicle is determined according to the matching degree, so that invalid matching caused by matching the system version of different classifications with all the upgrade data is avoided, system resources are saved, and meanwhile, the matching speed is improved.

Specifically, the current vehicle determines the connection relation between the target vehicle and the current vehicle, and builds the connection relation among a plurality of target vehicles, thereby realizing the construction of a connection relation diagram; wherein the connection relationship includes a communication-capable connection and a communication-incapable connection, for example, there are a target vehicle a and a target vehicle B, wherein it is first determined whether the current vehicle and the target vehicle a are capable of connecting communication, whether the current vehicle and the target vehicle B are capable of connecting communication, and then it is determined whether the target vehicle a and the target vehicle B are capable of connecting communication.
In some examples, after determining the connection relationship, at least one transfer path between each target vehicle and the current vehicle is obtained based on the connection relationship, the target vehicle and the current vehicle being capable of being communicatively connected via the transfer path; for example, as shown in fig. 5, there are target vehicles A, B and C, in which the target vehicle A, B and the current vehicle are capable of communication connection, and the target vehicle a and the target vehicle B are capable of communication connection, the target vehicle C is incapable of communication connection with the current vehicle, and the target vehicle C and the target vehicle a are capable of communication connection, then at this time, the transmission path between the current vehicle and the target vehicle a includes three kinds of: first kind: current vehicle-target vehicle a, second: current vehicle-target vehicle B-target vehicle a, third: current vehicle-target vehicle B-target vehicle C-target vehicle a; similarly, the transfer path between the current vehicle and the target vehicle B includes the following three types: first kind: current vehicle-target vehicle B, second: current vehicle-target vehicle a-target vehicle B, third: current vehicle-target vehicle a-target vehicle C-target vehicle B; likewise, the transfer path between the current vehicle and the target vehicle B includes four kinds of: first kind: current vehicle-target vehicle B-target vehicle C, second: current vehicle-target vehicle a-target vehicle C; third kind: current vehicle-target vehicle a-target vehicle B-target vehicle C; fourth kind: current vehicle-target vehicle B-target vehicle a-target vehicle C.

In the above example, the transmission path between the current vehicle and the target vehicle a includes the following three kinds of "first: current vehicle-target vehicle a, second: current vehicle-target vehicle B-target vehicle a, third: the present vehicle-target vehicle B-target vehicle C-target vehicle a″ is exemplified by determining transfer quality corresponding to each of the transfer paths by evaluating transfer quality of the first to third transfer paths, and if the first transfer path is highest in quality, the first transfer path is taken as a target transfer path between the target vehicle and the present vehicle, and if the second transfer path is highest in quality, the second transfer path is taken as a target transfer path between the target vehicle and the present vehicle, and if the third transfer path is highest in quality, the third transfer path is taken as a target transfer path between the target vehicle and the present vehicle.
According to the technical scheme provided by the embodiment of the application, the connection relation between each target vehicle and the current vehicle is determined, and the connection relation among a plurality of target vehicles is determined; acquiring at least one transfer path between each target vehicle and the current vehicle according to the determined connection relation; and carrying out transmission quality evaluation on each transmission path, and determining a target transmission path corresponding to each target vehicle according to a transmission quality evaluation result, wherein after determining at least the transmission paths, the transmission quality evaluation is carried out on each transmission path, so that the optimal transmission path is used as the target transmission path, and further, the subsequent transmission efficiency is improved.

s602, carrying out transmission quality evaluation on each transmission path based on the weight corresponding to each transmission path and the initial score value of each transmission path.
Specifically, the longer the transfer length of the transfer path is, the lower the initial score value corresponding to the transfer path is, the shorter the transfer field of the transfer path is, the higher the initial score value corresponding to the transfer path is, and the initial score value corresponding to each transfer path is determined according to the rule, where the transfer length is the number of times the current vehicle transfers to the target vehicle, for example, the transfer path is: the transfer length of the transfer path is 1 when the current vehicle is the target vehicle a; for another example, the transfer path is: the transfer length of the transfer path is 2 when the vehicle is currently a vehicle-target vehicle B-target vehicle a.
In some examples, the weight corresponding to each transfer path is determined according to the connection quality of each transfer path, wherein the higher the connection quality of the transfer path, the greater the weight of the transfer path, whereas the lower the connection quality of the transfer path, the lower the weight of the transfer path, wherein the connection quality is used to characterize the data transmission data and the data transmission delay.
Finally, weighting the initial score value corresponding to each transmission path according to the weight of each transmission path to obtain the score value corresponding to each transmission path; and then sorting the obtained score values, and taking the transmission path with the highest score as the target transmission path corresponding to the target vehicle.

In some examples, the current vehicle determines the upgrade urgency of each target vehicle, e.g., if the current vehicle determines that there is a safety hazard for the current system version of the target vehicle, the current vehicle determines that the upgrade urgency of the target vehicle is high, it being understood how the upgrade urgency of the target vehicle may be flexibly set by the relevant personnel.
In some examples, according to the upgrade priority and the upgrade urgency of each target vehicle, the upgrade order of each target vehicle is determined, for example, the upgrade priority and the upgrade urgency are added to obtain a score, then the upgrade order is determined according to the high-low value, and finally the target vehicles sequentially transmit target upgrade data to upgrade the target vehicles based on the upgrade order, so that the target vehicles are upgraded in stages, and the problems that the current vehicle load is overlarge and the data transmission speed is too slow due to simultaneous transmission of the target upgrade data to all the target vehicles are avoided.
