Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a power control method and a vehicle-mounted terminal. Background Art

[0002] At present, the number of pilot areas and demonstration cities for the Internet of Vehicles is gradually increasing. When building smart intersections based on technological innovation and business application development needs, some cities choose to deploy LTE-V (long-term evolution-vehicle) networks, and a small number of cities choose to deploy EUHT (Enhanced Ultra High Throughput) networks. However, the overall scale of smart intersection construction is still relatively small, and is often concentrated on a part of the road, without forming regional or large-scale continuous coverage. In order to meet the normal use of different networks, vehicle terminals are also beginning to tend to adopt terminals that support multiple standards. Due to the wide range of vehicle mobility, most of the driving time is not within the network coverage area of ​​the smart intersection, and vehicle-road-cloud data interaction is impossible. At this time, the communication modules of the multi-mode vehicle terminal still maintain the normal transmission working mode, which seriously wastes power consumption. Summary of the invention

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field based on this application belong to the scope of protection of the present invention.

[0048] At present, the overall scale of smart intersection construction is relatively small, and is often concentrated on only a part of the road, without forming regional or large-scale continuous coverage. In order to meet the normal use of different networks, vehicle terminals have also begun to support multi-standard terminals. This type of vehicle terminal is also called a multi-mode vehicle terminal. The multi-mode vehicle terminal is specifically configured with multiple communication modules, and these communication modules are suitable for different network standards.

[0049] Due to the wide range of vehicle movement, most of the time when the vehicle terminal is driving, it is not in the network coverage area of ​​the smart intersection. As long as the multi-mode vehicle terminal is powered on, all communication modules will transmit signals at normal power. When the vehicle terminal is not in the network coverage area, the transmission power of the whole device is high, which seriously wastes power consumption.

[0050] In order to solve this problem, an embodiment of the present invention provides a power control method, which is applied to a vehicle-mounted terminal, wherein the vehicle-mounted terminal is specifically configured with at least one first communication module, and each first communication module corresponds to a network standard. As an example, the external communication device may specifically include a road test unit, a base station, or other vehicles on the road.

[0051] For example, considering that smart intersections are usually deployed based on LTE-V networks or EUHT networks, the vehicle-mounted terminal may be specifically configured with an LTE-V communication module and an EUHT communication module.

[0052] See also Figure 1 , the method specifically comprises the following steps:

[0053] Step S101: In response to a first duration monitored for any network standard reaching a first preset duration, which represents the duration during which the vehicle-mounted terminal has not continuously adopted the network standard to interact with an external communication device, the transmission power of the first communication module corresponding to the network standard is reduced based on a first preset ratio.

[0054] In the embodiment of the present invention, power control is performed specifically on each first communication module as a unit, and the data interaction of the vehicle terminal under different network standards is monitored. Based on the continuous time T that the vehicle terminal has not used any network standard to interact with the external communication device, the network coverage of the location of the vehicle terminal is judged, and the transmission power of the corresponding first communication module is adaptively adjusted. Among them, the vehicle terminal has not used a network standard to interact with the external communication device for a continuous time T, which can also be understood as the vehicle terminal has not received data sent by the external communication device based on the network standard for a continuous time T.

[0055] The process of adaptively adjusting the transmission power is specifically that, if it is monitored that the duration T (i.e., the first duration) of data interaction with external communication equipment without adopting any network standard reaches T1 (i.e., the first preset duration), it is inferred that the area where the vehicle terminal is located is not covered by the corresponding network standard, and the first communication module corresponding to the network standard does not need to maintain a higher transmission power to work. Therefore, the transmission power of the first communication module corresponding to the network standard is reduced based on the first preset ratio.

[0056] When the device is initially powered on, each first communication module of the vehicle terminal can work at the initial whole-machine power, or initial transmission power. After the device is in normal working condition, the vehicle terminal periodically monitors the data interaction of each first communication module. Therefore, when it is monitored that the vehicle terminal has not continuously adopted any network standard to interact with the external communication device for a period of time T reaching T1, the transmission power of the first communication module corresponding to the network standard is adjusted based on the initial transmission power currently applied by the first communication module. The first preset ratio can be specifically understood as the ratio of reducing the transmission power of a first communication module based on its initial transmission power, or normal transmission power.

[0057] The specific value of the first preset ratio can be set based on actual needs. As an example, the first preset ratio can be set to 50%. In this case, if the first duration monitored for any network standard reaches the first preset duration, the transmission power of the first communication module corresponding to the network standard is reduced from the initial transmission power to 50% of the initial transmission power.

[0058] As a special example, in some scenarios, the first preset ratio may also be set to 0%, that is, the transmission power of the communication module is turned off.

[0059] The following uses an example in which the first communication module includes an LTE-V communication module and an EUHT communication module to illustrate the application process of the power control method provided by the implementation of the present invention.

[0060] For the two network standards of LTE-V and EUHT, during the driving process of the vehicle, depending on the different network coverage conditions at the location of the vehicle, there may be three typical scenarios:

[0061] (1) The vehicle enters the LTE-V coverage area without EUHT network coverage;

[0062] (2) The vehicle enters the EUHT coverage area without LTE-V network coverage;

[0063] (3) The vehicle enters an area without LTE-V coverage and EUHT coverage.

[0064] As far as the current on-board terminals are concerned, after the deployment of intelligent networked vehicles, as long as the vehicle is started and the terminal equipment is powered on, no matter which network coverage area the vehicle enters, each first communication module works at normal transmission power and the whole machine power output corresponds to the above three scenarios. The working states of each first communication module are as follows:

[0065] (1) When the vehicle enters the LTE-V coverage area, only the LTE-V communication module has data interaction requirements, and the EUHT communication module still transmits at normal power;

[0066] (2) When the vehicle enters the EUHT coverage area, only the EUHT communication module has data interaction requirements, and the LTE-V communication module still transmits at normal power;

[0067] (3) When a vehicle enters an area without LTE-V coverage and EUHT coverage, the LTE-V communication module and EUHT communication module must also transmit at normal power.

[0068] When the power control method provided by the embodiment of the present invention is applied, when there is no LTE-V coverage in the area where the vehicle is located, the on-board terminal cannot monitor the data interaction between the LTE-V and the road test unit, and when the duration of continuous no LTE-V data interaction is detected to reach T1, the transmission power of the LTE-V communication module is reduced based on the first preset ratio; when there is no EUHT coverage in the area where the vehicle is located, the on-board terminal cannot monitor the data interaction between the EUHT and the road test unit, and when the duration of continuous no EUHT data interaction is detected to reach T1, the transmission power of the EUHT communication module is reduced based on the first preset ratio. Therefore, when the power control method provided by the embodiment of the present invention is applied for power control, corresponding to the above three scenarios, the power control effects are as follows:

[0069] (1) The vehicle enters the LTE-V coverage area without EUHT network coverage: When the duration of continuous EUHT data interaction exceeds T1, the EUHT communication module operates at a reduced transmission power;

[0070] (2) The vehicle enters the EUHT coverage area and there is no LTE-V network coverage: When the duration of continuous no LTE-V data interaction exceeds T1, the LTE-V communication module operates at a reduced transmission power;

[0071] (3) The vehicle enters an area without LTE-V coverage and EUHT coverage: When the duration without LTE-V data interaction exceeds T1 and the duration without EUHT data interaction exceeds T1, both the EUHT communication module and the LTE-V communication module operate at reduced transmission power.

[0072] Based on the above description, it can be seen that by applying the power control method provided in the embodiment of the present invention, taking into account the mobility of vehicles and the characteristics of the deployment and construction of smart intersection networks, when the network coverage in the area where the vehicle-mounted terminal is located is different, based on the continuous duration T during which the vehicle-mounted terminal has not continuously adopted any network standard to interact with external communication equipment for data, it is possible to effectively infer whether the area where the vehicle-mounted terminal is located is covered by the corresponding network standard, and adaptively adjust the transmission power of the corresponding first communication module according to the monitoring result, thereby achieving the effect of retaining the normal transmission power of the first communication module with data interaction requirements, and applying the reduced transmission power to the first communication module without data interaction requirements.

[0073] The power control method provided by the embodiment of the present invention, when it detects that the vehicle-mounted terminal has not continuously adopted any network standard to interact with external communication equipment for data for a period exceeding a first preset time period, considers that the vehicle has not entered the coverage area of ​​the corresponding network standard, thereby reducing the transmission power used by the corresponding communication module. It can infer the actual network coverage situation based on the data interaction situation, maintain the normal transmission power of the communication module with data interaction requirements, reduce the transmission power of the communication module without data interaction requirements, save unnecessary transmission power energy consumption, and help to improve the equipment stability and life of the vehicle-mounted terminal.

[0074] When the first preset ratio is set to a value not greater than 50%, once the transmission power of the first communication module is adjusted, the energy-saving effect is more obvious, and compared with the current vehicle-mounted terminal transmission mode, at least 50% of energy can be saved.

[0075] In actual applications, in order to achieve the synergy between the vehicle-mounted terminal and the external communication device and realize intelligent driving decisions, the vehicle-mounted terminal not only needs to realize data interaction with the external communication device through the above-mentioned first communication module, but also needs to obtain the vehicle CAN (Controller Area Network) data of the vehicle equipped with the vehicle-mounted terminal, and specifically interact with the external communication device based on the vehicle CAN data, and make driving decisions based on the information interaction results.

[0076] Specifically, CAN is a serial communication protocol. Multiple ECUs (Electronic Control Units) on a vehicle can be connected to the CAN bus, so that the vehicle terminal can obtain the vehicle CAN data collected by these ECUs through the CAN bus. As an example, the vehicle CAN data may specifically include information such as the vehicle speed and steering wheel angle.

[0077] If the vehicle terminal cannot obtain the vehicle CAN data, even if the vehicle terminal is in the network coverage area of ​​the smart intersection, it cannot realize intelligent driving decision-making by exchanging data with external communication devices. Therefore, in practical applications, in addition to the typical scenarios (1)-(3) mentioned above, there is also the following typical scenario (4):

[0078] (4) The autonomous driving vehicle system has no CAN data. For example, in scenarios such as autonomous driving system failure, there is no data interaction between the vehicle CAN data and the on-board terminal for a long time.

[0079] As for the current vehicle-mounted terminal, if after the device is powered on, all first communication modules operate at normal transmission power, then corresponding to the above scenario (4), the working state of the first communication module is as follows:

[0080] (4) There is no data interaction between the on-board terminal and the CAN data of the autonomous driving vehicle for a long time, and communication modules such as the LTE-V communication module and the EUHT communication module all operate at normal transmission power.

[0081] It can be seen that when there is no data interaction between the vehicle terminal and the CAN data of the autonomous driving vehicle for a long time, since intelligent driving decisions cannot be made, if the first communication modules in the vehicle terminal maintain normal transmission power, it will lead to waste of power consumption. Therefore, in a possible implementation, the power control method provided by the present invention also includes:

[0082] In response to monitoring that the duration of continuous non-reception of vehicle CAN data reaches a second preset duration, the transmission power of all first communication modules is reduced based on a second preset ratio.

[0083] The second preset duration and the second preset ratio can be set according to actual needs. For example, the second preset duration can be consistent with the first preset duration, and the second preset ratio can be consistent with the first preset ratio.

[0084] Therefore, in the embodiment of the present invention, corresponding to the above scenario (4), the control results of each first communication module are as follows:

[0085] (4) When the duration of no continuous vehicle CAN data exceeds the second preset duration, the LTE-V communication module and the EUHT communication module both operate at the reduced transmission power.

[0086] In an embodiment of the present invention, for the scenario where vehicle CAN data is sent abnormally for a long time, all the first communication modules of the vehicle terminal operate at a reduced transmission power, which can avoid unnecessary data interaction between the first communication modules of the vehicle terminal and the external communication device when the vehicle CAN data is sent abnormally, thereby wasting power.

[0087] In one embodiment of the present invention, considering that data interaction may fluctuate to a certain extent, in order to avoid the problem that a rapid reduction in transmit power may cause device loss or affect normal service data interaction, a step-down adjustment strategy may be adopted for the transmit power of the communication module. In this embodiment, the power control method provided by the present invention further includes:

[0088] In response to a first duration monitored for any network standard reaching a third preset duration, the third preset duration being greater than the first preset duration, the transmission power of the first communication module corresponding to the network standard is reduced based on a third preset ratio.

[0089] For the convenience of description, in the embodiment of the present invention, the first preset duration and the third preset duration are respectively recorded as T1 and T2, and the first preset ratio and the third preset ratio are respectively recorded as N1% and N2%. Before applying the power control method provided in the embodiment of the present invention to perform power control, these four parameters need to be specified in advance, and T2 is greater than T1. In addition, in order to facilitate the setting of parameters, the first preset ratio and the second preset ratio can both refer to the ratio of the adjusted transmit power to the normal transmit power. In this case, it should be ensured that N2% is less than N1%. As an example, in order to ensure the power control effect, N1% can be configured to a number not less than 50%, and N2% can be configured to a number not greater than 10%. When tending to maximize the degree of power consumption saving, N2% can be configured to 0%.

[0090] Therefore, in the embodiment of the present invention, it can be specifically understood that the transmission power of the first communication module is lowered based on two different gears. The specific process of this power control is: for any network standard, when the duration of continuous no data interaction reaches T1, the transmission power of the first communication module corresponding to the network standard is reduced based on N1%, and the first communication module enters the low-power transmission mode; after the first communication module enters the low-power transmission mode, if there is still no data interaction under the network standard, and the duration of continuous no data interaction reaches T2, the transmission power of the first communication module is reduced based on N2%, and the first communication module enters the energy-saving transmission mode.

[0091] The following takes the case where a vehicle enters an area without EUHT coverage and the parameter configuration is T1=3 seconds, T2=6 seconds, N1%=50%, N2%=5% as an example to specifically explain the power control process:

[0092] After the vehicle enters the area without EUHT coverage, the multi-mode terminal cannot monitor the data interaction between the on-board terminal and the external communication device based on EUHT. When it is monitored that the duration T of continuous no EUHT data interaction reaches 3 seconds, the transmission power of the EUHT communication module is adjusted, and the EUHT communication module enters the low-power transmission mode and works at 50% of the normal transmission power; when it is monitored that the duration T of continuous no EUHT data interaction reaches 6 seconds, the transmission power of the EUHT communication module is further adjusted, and the EUHT communication module enters the energy-saving transmission mode from the low-power transmission mode and works at 5% of the normal transmission power.

[0093] Specifically, in actual applications, there is a certain degree of uncertainty in the intervals for data interaction between the vehicle terminal and the external communication device. If a single duration threshold T and a ratio of N% to reduce the transmission power are set, then in order to achieve the purpose of power control, N needs to be set larger, which can easily cause loss of components inside the communication module. In addition, if T is set too small, when it is detected that the vehicle terminal has no data interaction with the external communication device for a continuous period of time for any communication format, the corresponding communication module's transmission power is reduced. At this time, the vehicle may not actually have left the coverage area of ​​the communication format, which may affect the normal business interaction of the vehicle terminal under the network format. If T is set too large, it cannot achieve a good power saving effect.

[0094] Taking this into consideration, in the embodiment of the present invention, a relatively small set of T1 and N1, and a relatively large set of T2 and N2 are set to ensure that the transmission power of the communication module is gradually adjusted in a relatively slow manner. In this case, if it is monitored for any communication standard that the duration of the vehicle-mounted terminal not interacting with the external communication device continuously reaches T1, the transmission power of the corresponding communication module is reduced by only N1%. Even if the vehicle-mounted terminal has not actually driven out of the coverage area of ​​the network standard, the transmission power currently used by the corresponding communication module will not have too much impact on the subsequent normal business interaction. When it is monitored for the network standard that the duration of the vehicle-mounted terminal not interacting with the external communication device continuously reaches T2, the transmission power of the corresponding communication module is further reduced by N2%, thereby ensuring that the power control process can avoid the impact on normal business interaction on the basis of saving power consumption.

[0095] Based on the same principle, for the above scenario (4), that is, the vehicle terminal cannot monitor the vehicle CAN data, power control can also be performed by stepwise reducing the transmission power of each first communication module. Since the process is similar, it will not be repeated here, and this scenario will be illustrated by an example later.

[0096] In an embodiment of the present invention, when a long period of no data interaction is monitored for any network standard, two threshold values ​​T1 and T2 are set for the duration of continuous no data interaction. When the duration of continuous no data interaction reaches T1, the corresponding first communication module is first adjusted to enter a low-power transmission mode. When the duration of continuous no data interaction reaches T2, the corresponding first communication module is further adjusted to enter an energy-saving transmission mode. By gradually and smoothly reducing the transmission power of the first communication module, it is possible to save power consumption while avoiding affecting normal business interactions and avoiding losses of internal components of the communication module.

[0097] In one embodiment of the present invention, for the first communication module whose transmit power is reduced, a specific method for restoring its transmit power is also provided. In this embodiment, after the first duration monitored for any network standard reaches a first preset duration and the transmit power of the first communication module corresponding to the network standard is reduced based on a first preset ratio, it also includes:

[0098] In response to receiving data sent by an external communication device using the network standard, the transmission power of the first communication module corresponding to the network standard is restored to the initial transmission power.

[0099] It should be understood that this is different from the process of inferring whether the vehicle terminal is not covered by a specific network based on the duration of time that the vehicle terminal has not continuously used any network standard to interact with the external communication device. Once the vehicle terminal is able to monitor the interactive data sent by the external communication device using a specific network standard, it indicates that the vehicle terminal has entered the coverage area of ​​the corresponding network, and therefore it is necessary to immediately restore the corresponding first communication module transmission power to ensure the communication interaction range and service quality, regardless of the duration of the specific data interaction state.

[0100] Therefore, in an embodiment of the present invention, when it is monitored that no network standard has been used for data interaction with an external communication device for a long time and the transmission power of the first communication module corresponding to the network standard is reduced, once data sent by the external communication device based on the network standard is monitored, the transmission power of the corresponding first communication module is immediately restored to the normal transmission power.

[0101] As an example, if a vehicle enters an area without EUHT coverage, the vehicle-mounted terminal reduces the transmit power of the EUHT communication module based on the duration T of continuous no EUHT data interaction, and once the interaction data sent by the EUHT base station is monitored, the transmit power of the EUHT communication module is restored to the initial transmit power. Combined with the description in the foregoing embodiments of the present invention, when data sent by an external communication device based on EUHT is monitored, regardless of whether the EUHT communication module is currently in a low-power transmission mode or an energy-saving transmission mode, the transmit power of the EUHT communication module is directly restored to a normal transmission power.

[0102] In an embodiment of the present invention, after a long period of no data interaction is detected for any network standard and the transmission power of the first communication module corresponding to the network standard is reduced, once data sent by an external communication device using the network standard is monitored, the normal transmission power of the first communication module is restored, thereby effectively ensuring the communication interaction range and service quality.

[0103] Accordingly, in view of the situation where the transmission power of the first communication module is reduced due to the absence of vehicle CAN data, the present invention also provides a method for recovering the transmission power. In one embodiment of the present invention, after monitoring that the duration of continuous non-reception of vehicle CAN data reaches a second preset duration and the transmission power of all first communication modules is reduced based on the second preset ratio, it also includes:

[0104] In response to the received vehicle CAN data, the transmission power of all first communication modules is restored to the initial transmission power, or the transmission power of the first communication module corresponding to the target network standard is restored to the initial transmission power, and the target network standard represents the network standard used by the external communication device when sending data to the vehicle terminal within the most recent fourth preset time period.

[0105] In the scenario where the transmission power of all first communication modules is reduced due to the absence of vehicle CAN data, once the vehicle CAN data returns to normal, the vehicle-mounted terminal can realize intelligent driving decisions through data interaction with external communication devices. Therefore, when the vehicle CAN data is monitored, the transmission power of the first communication module can be restored.

[0106] It should be understood that regardless of the size of the transmission power being used by each first communication module of the vehicle terminal, or whether the transmission power is turned on, the vehicle terminal can normally receive the data sent by the external communication device. Therefore, when the vehicle terminal monitors the vehicle CAN data, if data sent by the external communication device is received recently (for example, within the most recent fourth preset time period), the network coverage area where the vehicle terminal is currently located can be inferred directly based on the communication method adopted by the external communication device. In this case, the corresponding network standard can be determined as the target network standard when the data sent by the external communication device is received most recently, and the transmission power of the first communication module corresponding to the target network standard can be restored to the initial transmission power. Among them, the fourth preset time period can be set based on actual needs.

[0107] In order to simplify the power control process, when the vehicle CAN data recovery is monitored, the transmission power of all first communication modules can be restored to the initial transmission power. Subsequently, based on the contents recorded in any of the foregoing embodiments of the present invention and based on the data interaction status between the vehicle terminal and the external communication device under each network standard, the power of each first communication module is controlled.

[0108] In an embodiment of the present invention, after monitoring that the vehicle CAN data is sent abnormally for a long time and the transmission power of all the first communication modules is reduced, once monitoring that the vehicle CAN data has returned to normal, the normal transmission power of all the first communication modules, or the normal transmission power of the first communication module corresponding to the target network standard, is restored. This ensures that after the vehicle CAN data returns to normal, the on-board terminal can interact with the external communication device in a timely manner and ensure the quality of the business interaction.

[0109] In one embodiment of the present invention, in addition to being able to perform power control based on the data interaction between the vehicle terminal and the drive test unit, power control can also be performed based on the application requirements of the vehicle. In this embodiment, the power control method provided by the present invention also includes:

[0110] In response to monitoring that the current Internet of Vehicles scenario is a specific scenario, where the specific scenario is a scenario in which there is no business application that depends on the high-speed network standard, the transmission power of the first communication module corresponding to the high-speed network standard is reduced based on a fourth preset ratio, and the high-speed network standard includes one or more of the following: EUHT communication network standard, 4G communication network standard and 5G communication network standard.

[0111] Specifically, in some scenarios, vehicles may only use LTE-V2V (long-term evolution-vehicle to vehicle) or LTE-V2I (long-term evolution-vehicle to infrastructure) application requirements, without video data or high-speed business requirements, and without the need to use EUHT networks or 4G, 5G networks, or high-speed network standards. In this scenario, it is also a waste to turn on the transmission power of the first communication module corresponding to these high-speed network standards for a long time, so the transmission power of these communication modules can be reduced.

[0112] In an embodiment of the present invention, the vehicle-mounted terminal can monitor the service needs of the vehicle. When it is detected that there is no video data or high-speed service demand, the transmission power of the first communication module corresponding to the high-speed network standard can be reduced based on the fourth preset ratio. Alternatively, the duration of continuous absence of such application demand can also be monitored. When the duration reaches a preset value, it is considered that it is not dependent on the high-speed network standard, and the corresponding transmission power of the first communication module is reduced. Similarly, when the power of the first communication module is controlled based on application demand, the transmission power of the corresponding communication module can also be stepped down based on the continuous duration of no continuous application demand that is dependent on the high-speed network standard.

[0113] In an embodiment of the present invention, power control is performed on the communication module corresponding to the high-speed network standard based on the application requirements of the vehicle, which can avoid the waste of power consumption caused by turning on the corresponding communication module for a long time when the vehicle has no application requirements that rely on the high-speed network standard, thereby further saving the power consumption of the vehicle terminal.

[0114] In one embodiment of the present invention, the first communication module includes any one or more of the following:

[0115] LTE-V communication module, EUHT communication module, 4G communication module, 5G communication module.

[0116] It should be understood that when the power control method provided in the embodiment of the present invention is applied to perform power control, the type and number of communication modules configured in the vehicle terminal are related to the actual scenario and are not limited to the communication modules listed above.

[0117] Figure 2 Schematic diagram of the power control method provided by an embodiment of the present invention. The following is an example of a heterogeneous network vehicle terminal supporting CAN, 4G, 5G, LTE-V, and EUHT communications. Figure 2 The process of applying the embodiments of the present invention to perform power control in four typical scenarios is exemplarily described:

[0118] The vehicle terminal supporting the above five communications is equipped with four first communication modules, namely, a 4G communication module, a 5G communication module, a LTE-V communication module and a EUHT communication module. Corresponding to the four typical scenarios (1) to (4) above, the normal working states of the four first communication modules are as follows:

[0119] (1) When the vehicle enters the LTE-V coverage area, only the LTE-V communication module has data interaction requirements, and the 4G communication module, 5G communication module, and EUHT communication module still transmit at normal power;

[0120] (2) When the vehicle enters the EUHT coverage area, only the EUHT communication module has data interaction requirements, and the 4G communication module, 5G communication module, and LTE-V communication module still transmit at normal power;

[0121] (3) When a vehicle enters an area without LTE-V coverage and EUHT coverage, the 4G communication module, 5G communication module, LTE-V communication module, and EUHT communication module must also transmit at normal power.

[0122] (4) There is no data interaction between the on-board terminal and the autonomous driving vehicle CAN data for a long time, and the 4G communication module, 5G communication module, LTE-V communication module, and EUHT communication module are all transmitting at normal power.

[0123] When the power control method provided in the embodiment of the present invention is applied to the vehicle-mounted terminal equipped with the above four first communication modules, the power control results of each first communication module in different typical scenarios are as follows: Figure 2 As shown in ①-④:

[0124] ① For the scenario of power control based on CAN data of autonomous driving vehicles: the on-board terminal determines whether there is no CAN data interaction. If not, the 4G, 5G, LTE-V, and EUHT communication modules work at normal transmission power. If so, it determines whether there is no CAN data interaction for T1 duration. If not, the 4G, 5G, LTE-V, and EUHT communication modules work at normal transmission power. If so, the 4G, 5G, LTE-V, and EUHT communication modules enter low-power transmission mode; when the 4G, 5G, LTE-V, and EUHT communication modules enter low-power transmission mode After that, it is determined whether there is no CAN data interaction for T2 time. If not, the 4G, 5G, LTE-V, and EUHT communication modules resume normal transmission power. If so, the 4G, 5G, LTE-V, and EUHT communication modules enter the energy-saving transmission mode. After the 4G, 5G, LTE-V, and EUHT communication modules enter the energy-saving transmission mode, it is determined whether there is still no data interaction with the vehicle CAN data. If not, the 4G, 5G, LTE-V, and EUHT communication modules resume normal transmission power. Otherwise, the 4G, 5G, LTE-V, and EUHT communication modules maintain the state.

[0125] ② For the scenario where the vehicle enters the LTE-V coverage area: the on-board terminal determines whether there is no EUHT data interaction. If not, the EUHT communication module works at normal transmission power. If so, it determines whether the absence of EUHT data interaction lasts for T1 time. If not, the EUHT communication module works at normal transmission power. If so, the EUHT communication module enters low-power transmission mode; after the EUHT communication module enters the low-power transmission mode, it determines whether the absence of EUHT data interaction lasts for T2 time. If not, the EUHT communication module restores normal transmission power. If so, the EUHT communication module enters energy-saving transmission mode; after the EUHT communication module enters the energy-saving transmission mode, it determines whether there is still no data interaction with the EUHT road test unit. If not, the EUHT communication module restores normal transmission power. Otherwise, the EUHT communication module maintains the state.

[0126] ③For the scenario where the vehicle enters the EUHT private network coverage area, since the vehicle can realize video data or high-speed services based on the EUHT network, 4G and 5G networks are usually not required. Therefore, it is appropriate to control the power of 4G and 5G communication modules in combination with application requirements: the on-board terminal determines whether there is no LTE-V data interaction and no 4G and 5G application requirements. If not, the LTE-V communication module works at normal transmission power. If so, it determines whether there is no LTE-V data interaction and no 4G and 5G application requirements for T1 duration. If not, the LTE-V, 4G, and 5G communication modules work at normal transmission power. If so, the LTE-V, 4G, and 5G communication modules enter low power. After the LTE-V, 4G, 5G communication module enters the low-power transmission mode, it is determined whether there is no LTE-V data interaction and no 4G, 5G application demand for T2 time. If not, the LTE-V, 4G, 5G communication module restores normal transmission power. If so, the LTE-V, 4G, 5G communication module enters the energy-saving transmission mode; after the LTE-V, 4G, 5G communication module enters the energy-saving transmission mode, it is determined whether there is still no data interaction with the LTE-V road test unit and no 4G, 5G application demand. If not, the LTE-V, 4G, 5G communication module restores normal transmission power. Otherwise, the LTE-V, 4G, 5G communication module maintains the state.

[0127] ④ For the scenario where the vehicle enters an area without LTE-V and EUHT private network coverage: the on-board terminal determines whether there is no LTE-V and EUHT data interaction. If not, the LTE-V and EUHT communication modules work at normal transmission power. If so, it determines whether the absence of LTE-V and EUHT data interaction lasts for T1 time. If not, the LTE-V and EUHT communication modules work at normal transmission power. If so, the LTE-V and EUHT communication modules enter low-power transmission mode; after the LTE-V and EUHT communication modules enter the low-power transmission mode, it determines whether the absence of LTE-V and EUHT data interaction lasts for T2 time. If not, the LTE-V and EUHT communication modules restore normal transmission power. If so, the LTE-V and EUHT communication modules enter energy-saving transmission mode; after the LTE-V and EUHT communication modules enter the energy-saving transmission mode, it determines whether there is still no data interaction with the LTE-V and EUHT road test units. If not, the LTE-V and EUHT communication modules restore normal transmission power. Otherwise, the LTE-V and EUHT communication modules maintain the state.

[0128] Based on the same inventive concept, the embodiment of the present invention also provides a vehicle-mounted terminal, see Figure 3 The vehicle terminal includes: a power control module and at least one first communication module (i.e. Figure 3 The first communication module 1 to the first communication module n) shown in the figure, each first communication module corresponds to a network standard;

[0129] A first communication module, used for communicating with an external communication device;

[0130] A power control module is used to respond to the first time length monitored for any of the network standards reaching a first preset time length, which represents the time length during which the vehicle-mounted terminal has not continuously adopted the network standard to interact with external communication equipment for data, and reduce the transmission power of the first communication module corresponding to the network standard based on a first preset ratio.

[0131] The vehicle-mounted terminal provided by the embodiment of the present invention, when it detects that the vehicle-mounted terminal has not continuously adopted any network standard to interact with external communication equipment for data for a period exceeding a first preset time period, considers that the vehicle has not entered the coverage area of ​​the corresponding network standard, thereby reducing the transmission power used by the corresponding communication module. It can infer the actual network coverage situation based on the data interaction situation, maintain the normal transmission power of the communication module with data interaction requirements, reduce the transmission power of the communication module without data interaction requirements, save unnecessary transmission power energy consumption, and help to improve the equipment stability and life of the vehicle-mounted terminal.

[0132] In one embodiment of the present invention, the power control module is further used for:

[0133] In response to monitoring that the duration of continuous non-reception of vehicle CAN data reaches a second preset duration, the transmission power of all first communication modules is reduced based on a second preset ratio.

[0134] In one embodiment of the present invention, the power control module is further used for:

[0135] In response to a first duration monitored for any network standard reaching a third preset duration, the third preset duration being greater than the first preset duration, the transmission power of the first communication module corresponding to the network standard is reduced based on a third preset ratio.

[0136] In one embodiment of the present invention, after the first duration monitored for any network standard reaches a first preset duration and the transmit power of the first communication module corresponding to the network standard is reduced based on the first preset ratio, the power control module is further used to:

[0137] In response to receiving data sent by an external communication device using the network standard, the transmission power of the first communication module corresponding to the network standard is restored to the initial transmission power.

[0138] In one embodiment of the present invention, after monitoring that the duration of continuous non-reception of vehicle CAN data reaches a second preset duration and reducing the transmission power of all first communication modules based on a second preset ratio, the power control module is further used to:

[0139] In response to the received vehicle CAN data, the transmission power of all first communication modules is restored to the initial transmission power, or the transmission power of the first communication module corresponding to the target network standard is restored to the initial transmission power, and the target network standard represents the network standard used by the external communication device when sending data to the vehicle terminal within the most recent fourth preset time period.

[0140] In one embodiment of the present invention, the first communication module includes any one or more of the following:

[0141] LTE-V communication module, EUHT communication module, 4G communication module, 5G communication module.

[0142] In one embodiment of the present invention, the power control module is further used for:

[0143] In response to monitoring that the current Internet of Vehicles scenario is a specific scenario, where the specific scenario is a scenario in which there is no business application that depends on the high-speed network standard, the transmission power of the first communication module corresponding to the high-speed network standard is reduced based on a fourth preset ratio, and the high-speed network standard includes one or more of the following: EUHT communication network standard, 4G communication network standard and 5G communication network standard.

[0144] The following takes the vehicle terminal that supports CAN, 4G, 5G, LTE-V, and EUHT communications as an example. Figure 4 The power control process of the power control module is described in detail. Figure 4 The communication format modules in the vehicle terminal include: CAN communication module, LTE-V communication module, EUHT communication module, 4G communication module and 5G communication module, among which the LTE-V communication module, EUHT communication module, 4G communication module and 5G communication module are the first communication modules for communicating with external communication devices.

[0145] Specifically, the complete process of the power control module performing power control on the first communication module can be understood as including five parts: whole machine power transmission mode, communication module-based power control mode, normal transmission power control mode, low power transmission mode and energy-saving transmission mode:

[0146] 1. Whole machine power transmission mode.

[0147] After the device is initially powered on, all communication modules work normally and the vehicle-mounted terminal transmits at the initial whole-machine power.

[0148] 2. Based on the communication module power control mode.

[0149] After the equipment is in normal working condition, the vehicle terminal periodically monitors the data interaction of each communication module to determine whether there is any received data, enters the power control mode according to the communication module, and performs modular power control.

[0150] 3. Normal transmit power mode.

[0151] After entering the communication module-based power control mode, each communication module maintains normal transmission power for a period of time.

[0152] 4. Low power consumption transmission mode.

[0153] When it is monitored that the duration of continuous no data interaction of any communication module meets the preset threshold T1, only the communication module with data interaction demand retains normal transmission power, and other communication modules enter low power transmission mode according to the preset duration T1 and the preset ratio N1%.

[0154] 5. Energy-saving transmission mode.

[0155] When it is monitored that the duration of continuous no data interaction of any communication module meets the preset threshold T2, only the communication module with data interaction demand retains normal transmission power, and other communication modules enter energy-saving transmission mode according to the preset duration T2 and the preset ratio N2%.
