Description

Technical Field

[0001] The present invention relates to the technical field of vehicle computer control, and in particular to a sentinel mode energy-saving control method, an electric vehicle, a control device, and a storage medium. Background Art

[0002] In order to ensure the safety of the vehicle during parking, a sensor module and a camera module will be installed on the vehicle. Users can choose to turn on the sentinel mode. In the sentinel mode, even if the vehicle is turned off, the battery in the vehicle will still keep powering the sensor module and the camera module. In order to save energy, the camera module stops running, and the sensor module remains started to detect the surrounding environment. When special circumstances occur in the environment, the sensor module can sense and form a trigger signal, triggering the camera module to start, and the camera module then captures images of the corresponding situation.

[0003] However, in actual use, it was found that even if only the sensor module was started for monitoring, the sensor module would consume considerable electrical energy to detect the surrounding area of ​​the vehicle. Continuous use would have a certain impact on the durability of the vehicle battery. At the same time, for new energy vehicles, the energy consumption when the sentinel mode is turned on accounts for about 15-20% of the total energy consumption, which cannot meet the user's requirements for energy saving. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a sentinel mode energy-saving control method and a tram, a control device, and a storage medium, providing a choice of coordinated sentinel monitoring, saving electric energy, and meeting the needs of users.

[0005] A sentry mode energy-saving control method according to an embodiment of the first aspect of the present invention is applied to a vehicle body, the vehicle body is provided with a wireless communication module, a sensor module, a camera module and a control module, the control module is respectively connected to the wireless communication module, the sensor module and the camera module, the sentry mode energy-saving control method comprises: broadcasting a collaborative sentry request; upon receiving a collaborative confirmation instruction, establishing an interconnection relationship with N other vehicles, and together becoming collaborative vehicles to form a collaborative vehicle group, wherein the collaborative confirmation instruction is issued by the N other vehicles that receive the collaborative sentry request, and N is greater than 1; obtaining status data of each collaborative vehicle based on the interconnection relationship, wherein the status data includes vehicle location information and a sensor coverage range of the vehicle, wherein the sensor coverage range is a range that can be detected by the sensor module of the vehicle; judging whether it is possible to enter together based on the status data of each collaborative vehicle Collaborative sentinel mode; if the collaborative sentinel mode can be entered together, a collaborative sentinel strategy is formulated, and after the collaborative sentinel strategy is formulated, the collaborative vehicles are disconnected from each other, wherein, under the collaborative sentinel strategy, one of the collaborative vehicles serves as a monitoring vehicle and the remaining collaborative vehicles serve as slave vehicles, and the monitoring vehicle is switched in turn among the collaborative vehicles according to a preset collaborative time, wherein the monitoring vehicle performs monitoring actions and the slave vehicles perform slave actions; in the monitoring vehicle, the sensor module detects the activities of objects in the environment to form a monitoring trigger signal, controls the camera module to start up to capture images according to the monitoring trigger signal, and broadcasts the monitoring trigger signal to the slave vehicle through the wireless communication module; in the slave vehicle, the sensor module and the camera module both stop running, and when the wireless communication module receives the monitoring trigger signal, controls the camera module to start up to capture images.

[0006] A sentinel mode energy-saving control method according to an embodiment of the present invention has at least the following beneficial effects:

[0007] The sentinel mode energy-saving control method of the present invention is that when a vehicle is parked and needs to enter the sentinel mode, the user can control the vehicle to send a collaborative sentinel request. For other vehicles near the vehicle, if the owner has set a mode that allows collaborative sentinels in advance, other vehicles can also send collaborative confirmation instructions after receiving the collaborative sentinel request. At this time, several vehicles together become collaborative vehicles to form a collaborative vehicle group, and then the position of each vehicle in the collaborative vehicle group and the sensing coverage range of the sensor module are judged. If the conditions are met, each collaborative vehicle in the collaborative vehicle group can formulate a collaborative sentinel strategy and enter the collaborative sentinel mode. After the collaborative sentinel strategy is formulated, the collaborative vehicles are disconnected from each other so as not to consume excess power. In the collaborative sentinel mode, according to the formulated collaborative sentinel strategy, there will be only one collaborative vehicle as a monitoring vehicle. The sensor module of the controlled vehicle remains turned on to detect within the sensor coverage area, while the sensor module and camera module of the slave-controlled vehicle are turned off. When the sensor module of the monitoring vehicle detects that there is object activity in the environment, it proves that the object may cause risks such as scratches to vehicles in the collaborative vehicle group. At this time, the monitoring vehicle not only controls its own camera module to start up to capture images according to the monitoring trigger signal, but also broadcasts the monitoring trigger signal to the slave-controlled vehicle through the wireless communication module. The slave-controlled vehicle also controls its own camera module to start up to capture images according to the monitoring trigger signal. During the entire collaborative sentinel mode process, each collaborative vehicle takes turns to become a monitoring vehicle according to the preset collaborative time, which greatly shortens the time for each vehicle to start up the sensor module in the sentinel mode. This design provides the option of collaborative sentinel monitoring, saves energy, and meets user needs.

[0008] According to some embodiments of the present invention, the process of determining whether the cooperative sentinel mode can be jointly entered based on the status data of each cooperative vehicle includes performing a coverage range determination step on each cooperative vehicle in turn, wherein the coverage range determination step includes: obtaining the sensor coverage range of the vehicle and the vehicle position information of all cooperative vehicles in the cooperative vehicle group; determining whether the positions of all cooperative vehicles are within the sensor coverage range of the vehicle; if so, performing a coverage range determination step on the next cooperative vehicle; if not, terminating the cooperative relationship between the vehicle and the cooperative vehicles whose positions are not within the sensor coverage range of the vehicle; until all cooperative vehicles in the cooperative vehicle group have performed the coverage range determination step, the cooperative vehicles that still maintain a cooperative relationship are allowed to enter the cooperative sentinel mode together.

[0009] According to some embodiments of the present invention, for a vehicle that has entered a collaborative sentinel mode and receives a collaborative sentinel request, status data of the vehicle that sent the collaborative sentinel request is obtained, and it is determined whether the position of the vehicle that sent the collaborative sentinel request is within the sensor coverage of all collaborative vehicles in the collaborative vehicle group, and it is determined whether the positions of all collaborative vehicles in the collaborative vehicle group are within the sensor coverage of the vehicle that sent the collaborative sentinel request; if so, the vehicle that sent the collaborative sentinel request is allowed to enter the collaborative vehicle group, and the collaborative vehicles in the collaborative vehicle group redefine the collaborative sentinel strategy; if not, the vehicle that has entered the collaborative sentinel mode ignores the collaborative sentinel request.

[0010] According to some embodiments of the present invention, the sentinel mode energy-saving control method also includes: when any cooperative vehicle in the cooperative vehicle group leaves its location, the leaving vehicle sends a cancellation coordination instruction; the remaining cooperative vehicles in the cooperative vehicle group receive the cancellation coordination instruction, and the leaving vehicle is removed from the cooperative vehicle group; the cooperative vehicles in the cooperative vehicle group re-formulate a cooperative sentinel strategy.

[0011] According to some embodiments of the present invention, in the broadcasting of the coordinated sentinel request, the wireless communication module broadcasts the coordinated sentinel request in a sentinel mode transmission range, wherein the sentinel mode transmission range is equal to or smaller than a sensing coverage range.

[0012] According to some embodiments of the present invention, in the collaborative sentinel strategy, the number of collaborative vehicles in the collaborative vehicle group is obtained, a preset collaborative time is set according to the number of vehicles, and the order in which each collaborative vehicle is switched to a monitoring vehicle is specified, wherein the greater the number of vehicles, the shorter the preset collaborative time; and in the collaborative sentinel strategy, the monitoring vehicle is triggered to switch to a slave vehicle according to the preset collaborative time, and the slave vehicles corresponding in sequence are switched to monitoring vehicles according to the preset collaborative time.

[0013] According to some embodiments of the present invention, the formulation of the collaborative sentinel strategy also includes setting a collaborative identification code for the collaborative vehicle group, and each collaborative vehicle stores the collaborative identification code before the collaborative vehicles are disconnected from each other; in the monitoring action, the monitoring vehicle binds the monitoring trigger signal with the collaborative identification code and broadcasts it to the slave-controlled vehicle through the wireless communication module; in the slave-controlled action, the slave-controlled vehicle compares the received collaborative identification code with the stored collaborative identification code, and if they are the same, controls the camera module to start to capture images according to the monitoring trigger signal, and if they are different, ignores the monitoring trigger signal.

[0014] According to the second aspect of the embodiment of the present invention, the electric vehicle is provided with a wireless communication module, a sensor module, a camera module and a control module, and the control module is connected to the wireless communication module, the sensor module and the camera module respectively, and the control module executes the sentinel mode energy-saving control method disclosed in any of the above embodiments to control the operation of the camera module.

[0015] The electric vehicle according to the embodiment of the present invention has at least the following beneficial effects:

[0016] The electric vehicle of the present invention executes the sentinel mode energy-saving control method disclosed in any of the above embodiments to control the operation of the camera module, provides the option of coordinated sentinel monitoring, saves electric energy, and meets the needs of users.

[0017] According to the control device of the embodiment of the third aspect of the present invention, the control device includes a memory and a processor, the memory stores a computer program, and the processor implements the sentinel mode energy-saving control method disclosed in any of the above embodiments when executing the computer program.

[0018] According to the computer-readable storage medium of the fourth aspect of the present invention, the computer-readable storage medium stores a computer program, and is characterized in that when the computer program is executed by a processor, the sentinel mode energy-saving control method disclosed in any of the above embodiments is implemented.

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0032] like Figure 1 As shown, a sentinel mode energy-saving control method according to an embodiment of the first aspect of the present invention is applied to a vehicle body 100, and the vehicle body 100 is provided with a wireless communication module 210, a sensor module 220, a camera module 230 and a control module 240, and the control module 240 is respectively connected to the wireless communication module 210, the sensor module 220 and the camera module 230.

[0033] Among them, the vehicle body 100 can be a conventional electric vehicle, a gasoline vehicle, etc. A battery is arranged in the vehicle body 100. The battery usually adopts a nickel-hydrogen battery. As a storage battery with good performance that has been widely used in recent years, the nickel-hydrogen battery has relatively stable charging and discharging characteristics. The nickel-hydrogen battery has strong reliability, long cycle life, can reach thousands of charging and discharging cycles, fully sealed structure, less maintenance required, excellent low temperature performance, etc. Therefore, the durability and storage capacity of the battery power supply can be improved. The battery powers the wireless communication module 210, the sensor module 220, the camera module 230 and the control module 240.

[0034] The camera module 230 may be one or more cameras disposed on the vehicle body 100 , and may generally acquire 360° image information of the surroundings of the vehicle body 100 .

[0035] The sensor module 220 may be a pyroelectric sensor, an ultrasonic sensor, a lidar, a vibration sensor, etc., and has a certain sensing coverage range. When movement or stillness occurs within the sensing coverage range, the sensor module 220 can generate a monitoring trigger signal to the control module 240 .

[0036] The control module 240 may be the central processing unit of the vehicle itself, and may be composed of a processing chip such as an MCU or a CPU and its associated circuits. The control module 240 may control the camera module 230 to capture and store surrounding image information according to the monitoring trigger signal fed back by the sensor module 220 .

[0037] The wireless communication module 210 can be a radio frequency chip, a 3G / 4G / 5G or other mobile communication chip, etc. The wireless communication module 210 can receive and send data, and can also establish an interconnection with the wireless communication modules 210 of other vehicles. After parking and turning off the engine, the wireless communication module 210 is in a low-frequency working state and can monitor signals transmitted in a certain range of channels. For example, when a user sends an unlocking signal through the remote control car key, the wireless communication module 210 can receive the unlocking signal and unlock the vehicle.

[0038] like Figure 2 As shown, the sentinel mode energy-saving control method includes:

[0039] S310, broadcasting a collaborative sentinel request;

[0040] S320, when receiving a collaborative confirmation instruction, establishing an interconnection relationship with N other vehicles, and together becoming collaborative vehicles to form a collaborative vehicle group, wherein the collaborative confirmation instruction is issued by the N other vehicles that receive the collaborative sentinel request, and N is greater than 1;

[0041] S330, acquiring status data of each coordinated vehicle based on the interconnection relationship, wherein the status data includes vehicle location information and a sensor coverage range of the vehicle, wherein the sensor coverage range is a range that can be detected by the sensor module 220 of the vehicle;

[0042] S340, judging whether the coordinated vehicles can enter the coordinated sentinel mode together based on the status data of each coordinated vehicle;

[0043] S350, if they can enter the collaborative sentinel mode together, a collaborative sentinel strategy is formulated, and after the collaborative sentinel strategy is formulated, the interconnection between the collaborative vehicles is disconnected, wherein, under the collaborative sentinel strategy, one of the collaborative vehicles is used as a monitoring vehicle, and the remaining collaborative vehicles are used as slave vehicles, and the monitoring vehicle is switched in turn among the collaborative vehicles according to the preset collaborative time, wherein the monitoring vehicle performs the monitoring action, and the slave vehicle performs the slave action;

[0044] S360: During the monitoring action, the sensor module 220 detects the activity of objects in the environment to form a monitoring trigger signal, controls the camera module 230 to start capturing images according to the monitoring trigger signal, and broadcasts the images to the slave controlled vehicle through the wireless communication module 210 according to the monitoring trigger signal;

[0045] S370: When the slave vehicle is in the slave control action, the sensor module 220 and the camera module 230 both stop running. When the wireless communication module 210 receives the monitoring trigger signal, the camera module 230 is controlled to start to capture images.

[0046] It is understandable that vehicles can be interconnected through their respective wireless communication modules 210 to achieve the sending and receiving of signals and data. At this time, a certain amount of electrical energy is required to power the wireless communication module 210. After the collaborative sentinel strategy is formulated, the interconnection between the collaborative vehicles is disconnected. At this time, the electrical energy required to be provided to the wireless communication module 210 will be greatly reduced. Generally speaking, the vehicle's wireless communication module 210 will be in a low-frequency working state and can monitor a certain range of channels in the environment. For example, the unlocking signal sent by the remote control car key can be received by the wireless communication module 210, and the monitoring trigger signal sent by the monitored vehicle in the form of broadcast can also be obtained by the wireless communication module 210. Therefore, the low-frequency monitoring function that already exists in the wireless communication module 210 is used here to monitor the monitoring trigger signal sent by the monitored vehicle, which will not cause additional power loss.

[0047] In addition, when there are temporarily no other vehicles on the scene that can form a collaborative sentinel request mode with this vehicle, the owner can set the collaborative sentinel mode to be open and allowed in the vehicle's touch screen and other operating modules. At this time, the vehicle's wireless communication module 210 can also monitor channels within a certain range in the environment. When other vehicles are parked nearby and other vehicles send collaborative sentinel requests in broadcast form, the vehicles can try to establish a collaborative sentinel request mode.

[0048] Specifically, in the collaborative sentinel strategy, in the same collaborative vehicle group, the preset collaborative time can be 30 minutes, 1 hour, 2 hours, etc. For example, there are three collaborative vehicles in the collaborative vehicle group, and the preset collaborative time is 1 hour. The first collaborative vehicle is used as a monitoring vehicle, and the second and third collaborative vehicles are used as slave vehicles. After the monitoring vehicle has been detected for 1 hour, the second collaborative vehicle is used as a monitoring vehicle, and the first and third collaborative vehicles are used as slave vehicles. After the monitoring vehicle has been detected for 1 hour, the third collaborative vehicle is used as a monitoring vehicle, and the first and second collaborative vehicles are used as slave vehicles, and then the cycle is repeated until a collaborative vehicle needs to leave.

[0049] According to the sentinel mode energy-saving control method of the present invention, when a vehicle is parked and needs to enter the sentinel mode, the user can control the vehicle to send a collaborative sentinel request. For other vehicles near the vehicle, if the owner has set a mode that allows collaborative sentinels in advance, other vehicles can also send collaborative confirmation instructions after receiving the collaborative sentinel request. At this time, several vehicles together become collaborative vehicles to form a collaborative vehicle group, and then the positions of each vehicle in the collaborative vehicle group and the sensing coverage range of the sensor module 220 are judged. If the conditions are met, each collaborative vehicle in the collaborative vehicle group can formulate a collaborative sentinel strategy and enter the collaborative sentinel mode. After the collaborative sentinel strategy is formulated, the collaborative vehicles are disconnected from each other so as not to consume excess power. In the collaborative sentinel mode, according to the formulated collaborative sentinel strategy, there will be only one collaborative vehicle as a monitoring vehicle, and the sensor module 220 of the monitoring vehicle 0 remains on, and detects within the sensor coverage area, while the sensor module 220 and camera module 230 of the slave-controlled vehicle are turned off. When the sensor module 220 of the monitoring vehicle detects that there is object activity in the environment, it proves that the object may cause risks such as scratches to the vehicles in the cooperative vehicle group. At this time, the monitoring vehicle not only controls its own camera module 230 to start up to capture images according to the monitoring trigger signal, but also broadcasts the monitoring trigger signal to the slave-controlled vehicle through the wireless communication module 210. The slave-controlled vehicle also controls its own camera module 230 to start up to capture images according to the monitoring trigger signal. During the entire collaborative sentinel mode, each collaborative vehicle takes turns to become a monitoring vehicle according to the preset collaborative time, which greatly shortens the time for each vehicle to start the sensor module 220 in the sentinel mode. The present design provides the option of collaborative sentinel monitoring, saves energy, and meets the needs of users.

[0050] In some embodiments of the present invention, Figure 3 , 4 As shown, the step of judging whether to enter the cooperative sentinel mode together based on the status data of each cooperative vehicle includes a step of judging the coverage range of each cooperative vehicle in turn, wherein the step of judging the coverage range includes:

[0051] S410, obtaining the sensing coverage of the vehicle and the vehicle position information of all cooperative vehicles in the cooperative vehicle group;

[0052] S420, determining whether the positions of all cooperative vehicles are within the sensing coverage of the vehicle;

[0053] S430: If yes, then perform a coverage range determination step for the next cooperative vehicle;

[0054] S440: If no, cancel the cooperative relationship between the vehicle and the cooperative vehicle whose location is not within the sensing coverage of the vehicle;

[0055] S450, until all cooperative vehicles in the cooperative vehicle group have completed the coverage range judgment step, the cooperative vehicles that still maintain a cooperative relationship are allowed to enter the cooperative sentinel mode together.

[0056] It can be understood that the sensor module 220 on each vehicle body 100 has a certain sensor coverage range. When several vehicles are parked close to each other, the position of each vehicle is within the sensor coverage range of each vehicle. This means that no matter which vehicle's sensor module 220 starts detection, it can roughly detect the environment for all cooperative vehicles in the cooperative vehicle group.

[0057] Among them, the vehicle location information can be provided after the satellite positioning chip of each vehicle detects the location of its own vehicle, and the sensor coverage range of each vehicle is determined according to its own sensor module 220. For example, the sensor coverage range of some sensor modules 220 is a circular range formed with the location of the own vehicle as the origin.

[0058] In the coverage range judgment step, when the position of a cooperative vehicle is not within the sensor coverage range of a certain vehicle, the two vehicles can be marked first to terminate the cooperative relationship between the two vehicles. Then, after judging the sensor coverage range of all vehicles, the vehicle that has terminated the cooperative relationship with the most vehicles will be kicked out of the cooperative vehicle group. Then, it will be judged whether all the cooperative vehicles in the cooperative vehicle group have a cooperative relationship. If so, the cooperative sentinel mode is entered. If not, the vehicle that has terminated the cooperative relationship with the most vehicles will be kicked out of the cooperative vehicle group. The process is carried out in sequence until all the cooperative vehicles in the cooperative vehicle group have a cooperative relationship.

[0059] In order to improve processing efficiency and ensure that vehicles that can receive collaborative sentinel requests can basically meet the conditions of the coverage range judgment step, in some embodiments of the present invention, in the broadcast of the collaborative sentinel request, the wireless communication module 210 broadcasts the collaborative sentinel request in a sentinel mode transmission range, wherein the sentinel mode transmission range is equal to or less than the sensing coverage range.

[0060] Generally speaking, a collaborative sentinel request is transmitted after the vehicle stops. When transmitting the collaborative sentinel request, the wireless communication module 210 adjusts the transmission power to restrict the transmission range of the sentinel mode. Only other vehicles within the transmission range of the sentinel mode can receive the collaborative sentinel request. Since the transmission range of the sentinel mode is equal to or smaller than the sensing coverage range, the position of the vehicle that can receive the collaborative sentinel request can basically be within the sensing coverage range of the vehicle that transmits the collaborative sentinel request. In addition, it can be understood that if the two collaborative vehicles that are farthest apart in the collaborative vehicle group meet the requirement that the position of one of the vehicles is within the sensing coverage range of the other vehicle, then generally all the collaborative vehicles in the collaborative vehicle group meet the coverage range judgment step. Therefore, the sentinel mode transmission range can be made less than half of the sensing coverage range, and the vehicle that transmits the collaborative sentinel request is located at the center position. Then, it is highly likely that all the collaborative vehicles in the collaborative vehicle group meet the coverage range judgment step, thereby improving the processing efficiency of the coverage range judgment step.

[0061] In some embodiments of the present invention, for a vehicle that has entered the collaborative sentinel mode and receives a collaborative sentinel request, status data of the vehicle that sent the collaborative sentinel request is obtained, and it is determined whether the position of the vehicle that sent the collaborative sentinel request is within the sensor coverage of all the collaborative vehicles in the collaborative vehicle group, and it is determined whether the positions of all the collaborative vehicles in the collaborative vehicle group are within the sensor coverage of the vehicle that sent the collaborative sentinel request;

[0062] If so, the vehicle that sent the cooperative sentinel request is allowed to enter the cooperative vehicle group, and the cooperative vehicles in the cooperative vehicle group re-formulate the cooperative sentinel strategy;

[0063] If not, the vehicle that has entered the cooperative sentry mode ignores the cooperative sentry request.

[0064] For multiple vehicles that have entered the collaborative sentinel mode, when a new collaborative sentinel request is received, the vehicles that are already in the collaborative vehicle group have all been processed through the coverage range judgment step. Therefore, only the position of the vehicle that newly requests to join and the sensor coverage range need to be judged. Only when the position of the vehicle sending the collaborative sentinel request is within the sensor coverage range of all collaborative vehicles in the collaborative vehicle group, and the positions of all collaborative vehicles in the collaborative vehicle group are within the sensor coverage range of the vehicle sending the collaborative sentinel request, will the vehicle that newly requests to join be allowed to join the collaborative vehicle group. Otherwise, all collaborative vehicles in the collaborative vehicle group will ignore or block the collaborative sentinel request.

[0065] In some embodiments of the present invention, Figure 5 As shown, the sentinel mode energy-saving control method also includes:

[0066] S510, when any one of the coordinated vehicles in the coordinated vehicle group leaves the location, the departing vehicle sends a cancellation command;

[0067] S520: The remaining cooperative vehicles in the cooperative vehicle group receive a decoupling instruction, and then the departing vehicles are decoupled from the cooperative vehicle group;

[0068] S530. The cooperative vehicles in the cooperative vehicle group re-formulate the cooperative sentinel strategy.

[0069] When the vehicle needs to leave, for example, when the owner starts the ignition or moves the vehicle, the wireless communication module 210 of the vehicle broadcasts a command to release the coordination. The remaining cooperative vehicles in the cooperative vehicle group receive the command to release the coordination and then redefine the cooperative sentinel strategy among the remaining vehicles. If there is only one vehicle left in the cooperative vehicle group, the vehicle can issue a cooperative sentinel request to form a new cooperative vehicle group with other vehicles.

[0070] In some embodiments of the present invention, in the cooperative sentinel strategy, the number of cooperative vehicles in the cooperative vehicle group is obtained, a preset cooperative time is set according to the number of vehicles, and the order in which each cooperative vehicle switches to a monitoring vehicle is specified, wherein the greater the number of vehicles, the shorter the preset cooperative time;

[0071] And in the cooperative sentinel strategy, the monitoring vehicle is triggered to switch to the slave vehicle according to the preset cooperative time, and the corresponding slave vehicles in sequence are switched to the monitoring vehicle according to the preset cooperative time.

[0072] It can be understood that the vehicle body 100 can first set the total cycle time, and the total cycle time can be 2 hours, 3 hours, 6 hours, etc. In formulating the collaborative sentinel strategy, the preset collaborative time can be set according to the number of vehicles. Specifically, after obtaining the number of collaborative vehicles in the collaborative vehicle group, for example, the number of collaborative vehicles is 3, and the preset total cycle time is 3 hours, then the preset collaborative time is the total cycle time divided by the number of collaborative vehicles, which is equal to 1 hour. Therefore, the collaborative sentinel strategy is that the first collaborative vehicle is first used as a monitoring vehicle, and the second and third collaborative vehicles are used as slave-controlled vehicles. After the monitoring vehicle has been detected for 1 hour, the second collaborative vehicle is used as a monitoring vehicle, and the first and third collaborative vehicles are used as slave-controlled vehicles. After the monitoring vehicle has been detected for 1 hour, the third collaborative vehicle is used as a monitoring vehicle, and the first and second collaborative vehicles are used as slave-controlled vehicles, and then the cycle is repeated until a collaborative vehicle needs to leave.

[0073] In some embodiments of the present invention, the formulation of the cooperative sentinel strategy further includes setting a cooperative identification code of the cooperative vehicle group, and each cooperative vehicle stores the cooperative identification code before disconnecting the interconnection between the cooperative vehicles;

[0074] During the monitoring action, the monitoring vehicle binds the monitoring trigger signal with the cooperative identification code and broadcasts it to the slave vehicle through the wireless communication module 210;

[0075] During the slave control action, the slave vehicle compares the received collaborative identification code with the stored collaborative identification code. If they are the same, the camera module 230 is controlled to start capturing images according to the monitoring trigger signal. If they are different, the monitoring trigger signal is ignored.

[0076] In the same cooperative vehicle group, a cooperative identification code or a preset cooperative identification code can be randomly generated before each cooperative vehicle is disconnected from the other, and then each cooperative vehicle stores the cooperative identification code so that when a monitoring trigger signal is received in the future, a cooperative identification code comparison can be performed first to reduce the probability of false triggering. In the case where the received cooperative identification code is different from the stored cooperative identification code, the corresponding monitoring trigger signal can be ignored or blocked.

[0077] According to the electric vehicle of the second aspect of the present invention, Figure 1 As shown, a wireless communication module 210, a sensor module 220, a camera module 230 and a control module 240 are provided. The control module 240 is respectively connected to the wireless communication module 210, the sensor module 220 and the camera module 230. The control module 240 executes the sentinel mode energy-saving control method disclosed in any of the above embodiments to control the operation of the camera module 230.

[0078] The specific structure of the electric vehicle may be similar to that of the vehicle body 100 and will not be described in detail here.

[0079] The electric vehicle of the present invention executes the sentinel mode energy-saving control method disclosed in any of the above embodiments to control the operation of the camera module 230, provides the option of coordinated sentinel monitoring, saves electric energy, and meets the needs of users.

[0080] According to the control device of the third aspect of the embodiment of the present invention, the control device includes a memory 620 and a processor 610, the memory 620 stores a computer program, and the processor 610 implements the sentinel mode energy-saving control method disclosed in any of the above embodiments when executing the computer program.
