The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a remote driving processing method according to an embodiment of the present application.
Referring to fig. 1, the scheme of the embodiment of the present application includes:
s101, when the vehicle is controlled to drive by the remote control end through the first network, if the disconnection of the signal of the first network is detected, the first network connected between the vehicle and the remote control end is switched to a second network.
In the step, the vehicle is connected with the remote control end through a first network, and the vehicle is controlled to drive by the remote control end. The first network may be a 5G network, and the second network may be a 4G network, but is not limited thereto.
And S102, after the vehicle is switched to the second network, the degraded transmission data is executed so that the remote control end can continuously control the vehicle remotely.

According to the scheme provided by the embodiment of the application, when the vehicle is controlled to drive by the remote control end through the first network, if the signal disconnection of the first network is detected, the first network connected between the vehicle and the remote control end is switched to the second network; and after switching to the second network, performing degraded transmission data so that the remote control end can continue to remotely control the vehicle.

Fig. 2 is another schematic flow chart of a remote driving processing method according to an embodiment of the present application, and fig. 2 further describes a scheme according to the embodiment of the present application in comparison with fig. 1.
Referring to fig. 2, the scheme of the embodiment of the present application includes:
s201, when the vehicle is controlled to drive by the remote control end through the 5G network, if the disconnection of the signal of the 5G network is detected, the 5G network connected between the vehicle and the remote control end is switched to the 4G network.
When the vehicle is connected with the remote control end through the 5G network, the 5G network has lower time delay and better transmission capability, so that the multi-channel video data of the vehicle can be transmitted through the 5G network.
Because the delay of the 5G signal is smaller than that of the 4G signal, if it is detected that the delay of the current network signal is greater than a specific threshold, it may be determined that the 5G network signal is detected to be disconnected, and at this time, the 4G network environment may be switched to.
S202, the multi-channel video data transmission of the vehicle is changed into single-channel video data transmission.
In the step, originally, the transmission of the multi-channel video data by the 5G network can be changed into the transmission of the single-channel video data by the 4G network, so that the occupied bandwidth can be reduced. In some embodiments, the transmitted one-way video data may be, for example, video data for acquiring a road condition or environment in front of the vehicle.
S203, according to the comparison between the uplink and downlink rates of the second network signal and a plurality of set thresholds, corresponding different video compression ratios are determined.
In this step, after comparing the uplink and downlink rates of the 4G network with a plurality of set thresholds, the uplink and downlink rates of the 4G network can be divided into a plurality of different bandwidth ranges according to different set thresholds, and then the corresponding video compression ratio is determined according to the bandwidth range in which the current 4G network is located.
And S204, compressing the video data according to different video compression ratios and transmitting the compressed video data so that the remote control end can continuously control the vehicle remotely.
In this step, if the rate of the 4G network is within a certain bandwidth range, the video data may be compressed according to a video compression ratio corresponding to the bandwidth range, and then the compressed video data is transmitted, so that the remote control end continues to remotely control the vehicle.
According to the scheme provided by the embodiment of the application, in the degradation transmission process, the multi-channel video data are changed into the single-channel video data, and/or the single-channel video data are compressed, so that the occupied bandwidth can be reduced, the basic conditions required by remote driving can be maintained after the 5G network is switched to the 4G network, the video data transmission rate is improved, and the remote driving experience is improved.
Fig. 3 is another schematic flow chart of a remote driving processing method according to an embodiment of the present application, and fig. 3 describes a scheme according to an embodiment of the present application in more detail than fig. 1 and fig. 2.
Referring to fig. 3, the scheme of the embodiment of the present application includes:
and S301, connecting the vehicle with a remote control end through a 5G network.
In the step, when the vehicle is connected with the remote control end through the 5G network to execute remote driving, vehicle control data and multi-channel video data are transmitted between the vehicle and the remote control end.
The vehicle control data may include one or a combination of the following data: steering angle of steering wheel, accelerator pedal state, brake pedal state, turn light state, car light on-off state, gear state.
And S302, judging whether the 5G signal of the vehicle is disconnected or not, if the 5G signal of the vehicle is disconnected, entering S303, and if the 5G signal of the vehicle is not disconnected, returning to S301.
In this step, since the delay of the 4G network is greater than that of the 5G network, if it is detected that the delay of the current network signal is greater than a specific threshold, it may be determined that the 5G signal is disconnected, and the 4G network environment is entered.
And S303, switching the 5G network connected between the vehicle and the remote control terminal to a 4G network.
In this step, when the 5G network is disconnected, the processing method in the related art is generally to brake the vehicle and engage the P-gear, and at this time, the multi-channel video signal is disconnected. In the embodiment, the 5G network connected between the vehicle and the remote control end is switched to the 4G network to maintain the basic conditions of remote driving, so that the remote control end can continue to remotely control the vehicle through the 4G network.
And S304, transmitting the vehicle control data of the vehicle through the 4G network.
In this embodiment, the transmission capability of the 4G network is weaker than that of the 5G network, but the transmission capability is sufficient for transmitting the vehicle control data and the compressed video data of the vehicle.
S305, the multi-channel video data transmission of the vehicle is changed into single-channel video data transmission.
In the 5G network environment, the vehicle generally transmits multiple paths of video data with the remote control terminal through the 5G network, and because the 4G network has poor transmission capability for multiple paths of video data, the transmission of multiple paths of video data of the vehicle can be changed into the transmission of single path of video data, so that the occupied bandwidth can be reduced.
The one-way video data may be, for example, video data for acquiring a road condition or an environment in front of the vehicle.
It should be noted that there is no sequential relationship between S305 and S304.
S306, according to the comparison between the uplink and downlink rates of the 4G network signal and a plurality of set thresholds, corresponding different video compression ratios are determined.
In this step, after comparing the uplink and downlink rates of the 4G network with a plurality of set thresholds, the uplink and downlink rates of the 4G network can be divided into a plurality of different bandwidth ranges according to different set thresholds, and then the corresponding video compression ratio is determined according to the bandwidth range in which the current 4G network is located.
In some embodiments, the correspondence between the uplink and downlink bandwidth ranges and the video compression ratio of the 4G network can be referred to the following table 1:
| uplink and downlink bandwidth range | Video compression ratio |
| Greater than A1 | B1 |
| A2-A1 | B2 |
| A3-A2 | B3 |
Table 1
In table 1 above, parameters a1, a2, and A3 are different thresholds of uplink and downlink bandwidths of the 4G network, respectively, and a1, a2, and A3 may be arranged in order from large to small; the parameters B1, B2 and B3 are different video compression ratios respectively, and B1, B2 and B3 can be arranged from small to large in sequence.
The uplink and downlink rates of the 4G network are divided into 3 different bandwidth ranges through thresholds A1, A2 and A3, namely A3-A2, A2-A1 and the bandwidth ranges are larger than A1.
When the uplink and downlink rate of the 4G network is greater than A1, the corresponding video compression ratio is B1; when the uplink and downlink rates of the 4G network are between A2 and A1, the corresponding video compression ratio is B2; when the uplink and downlink rates of the 4G network are between A3 and a2, the corresponding video compression ratio is B3.
The specific values of the parameters A1, A2 and A3 and the values of the parameters B1, B2 and B3 can be calibrated according to actual needs.
It is understood that the present embodiment is not limited to setting the bandwidth range of the 4G network as shown in the table above, and the bandwidth of the 4G network may also be divided into more than the above number of ranges or less than the above number of ranges according to actual needs, which is described above only by way of example and is not limited by the present embodiment.
And S307, compressing the video data according to different video compression ratios and transmitting the compressed video data so that the remote control end can continuously control the vehicle remotely.
In this step, if the current 4G network is within a certain bandwidth range, the video data is compressed according to the video compression ratio corresponding to the bandwidth range and then transmitted, for example, if the bandwidth range of the current 4G network is within a range from a2 to a1 in the above table, the video data may be compressed according to the compression ratio B2 corresponding to the bandwidth range and transmitted.
It can be seen that, according to the scheme provided by this embodiment, after the 4G network is switched to, in the process of degrading data transmission, corresponding different video compression ratios can be determined according to the comparison between the uplink and downlink rates of the 4G network signal and a plurality of set thresholds, and then the video data is compressed according to the different video compression ratios and transmitted, so that the transmission stability and transmission rate of the video data in the 4G network are ensured, the system response speed is increased, the remote control end continues to control the vehicle more effectively, and the user experience is further improved.
It should be further noted that in some embodiments, when the uplink and downlink rates of the 4G network are lower than the minimum set threshold, data transmission is difficult to guarantee or easy to lose, so that the vehicle can be braked and stopped remotely. For example, as A3 in the above table may be a threshold for the maximum value, when the uplink and downlink rate of the 4G network is less than A3, the vehicle may be braked and stopped under remote control, and then the vehicle may be controlled to stop in a safe area, so that the safety of remote driving can be ensured.
In some embodiments, when the 5G network signal recovery is detected, the connection between the vehicle and the remote control terminal may be switched from the 4G network back to the 5G network.
In the practical application scene, after the 5G signal disconnection, probably resume in the short time, during the disconnection period of 5G signal, can be connected with the remote control end through the 4G network, after the 5G signal resumes, be connected with the remote control end through the 5G network, make the remote control end control vehicle through the 5G network again, handle the back like this, in the remote driving process, can realize keeping driving continuously through the mutual switching of 5G and 4G network control vehicle, driving safety has not only been guaranteed, and user experience has also been promoted.
Corresponding to the embodiment of the application function implementation method, the application also provides a remote driving processing device, a vehicle and a corresponding embodiment.
