Description

Vehicle stopping maintenance method and vehicle
Technical Field
The present invention relates generally to the field of vehicle networking control. More particularly, the present invention relates to a vehicle stop maintenance method, a computer-readable storage medium, a computing device, and a vehicle.
Background
During lockout periods (e.g., a minimum of 14 days, 1 month, 2 months, or even longer), many vehicles are parked for extended periods in parking lots in these residential communities and commercial buildings. After each lockout period is completed, there are many problems such as the consumption of electricity or damage to the battery of the vehicle, mold in the cabin, etc.
Currently, to avoid these problems, the vehicle owner must manually start the vehicle to charge the battery and turn on the air conditioner to dehumidify. For some reason, owners often cannot maintain their vehicles in close proximity. Although some vehicles support remote control, the vehicle owner can remotely start the vehicle through the APP on the cell phone, this approach requires the vehicle owner to manually start the vehicle at a certain frequency (e.g., every 7 days) throughout the lockout period (e.g., 2 months), which places an additional burden on the vehicle owner.

Currently, owners of vehicles often cannot access their vehicles for maintenance during lockout periods, such as charging the batteries of the vehicles. Even if the vehicle is started remotely by APP on the cell phone, the vehicle owner is required to start the vehicle manually at a certain frequency (e.g., every 7 days) throughout the lockout period (e.g., 2 months), which places an additional burden on the vehicle owner.
To this end, an embodiment of the present invention proposes a vehicle stop maintenance method including: receiving vehicle stopping information via the on-board networking device; acquiring an initial state of charge of a storage battery of the vehicle; and controlling an engine and/or a power battery of the vehicle to charge the battery based on the vehicle stop information, the initial state of charge, and the target state of charge of the battery. The method can automatically control the engine and/or the power battery of the vehicle to charge the storage battery without manually starting the vehicle, and greatly improves convenience while avoiding economic loss of a vehicle owner.
The following describes the invention in terms of several embodiments. Fig. 1 illustrates a vehicle stop maintenance method according to an embodiment of the present invention. The method may be performed by a Body Control Module (BCM) or other control device of the vehicle. In step 11, vehicle stop information is received via the in-vehicle networking device. The vehicle-mounted networking device (such as a T-BOX) of the vehicle communicates with a cloud server of the host factory via a mobile network (such as a 4G, 5G network), and periodically transmits vehicle-related data, such as battery status, driving data, and the like, to the cloud server. The cloud server determines the geographic location where the vehicle is currently located by communicating with the in-vehicle networking device via the mobile network. The cloud server may also communicate with a client device (e.g., a portable device such as a cell phone) via a mobile network, thereby implementing functions of controlling a vehicle from the client device, viewing a vehicle status via the client device, and the like. For example, the cloud server receives information input by a user from a client device and transmits the information to an in-vehicle networking device after processing to control the vehicle. For another example, the cloud server receives vehicle status information from the in-vehicle networking device and sends it to the client device for presentation to a user (e.g., a vehicle owner). The vehicle stop information may include a vehicle stop period (e.g., an expected lockout period, including the start and duration/end times of lockout). Vehicle stop information may be generated in a variety of ways. For example, a user inputs vehicle stop information via a client device and sends the vehicle stop information to a cloud server, which then sends the vehicle stop information to an on-board networking device. For another example, the cloud server analyzes the position of the vehicle and related information (such as a map and related data on the internet), if it is determined that the vehicle will not be used for a long time, a reminding message is pushed to the user via the client device, and after checking and confirming, the vehicle stopping information is sent to the vehicle-mounted networking device. For another example, the cloud server analyzes the position of the vehicle and related information (such as a map and related data on the internet), and directly sends the vehicle stopping information to the vehicle-mounted networking equipment.
In step 12, an initial state of charge (SOC) of a battery of the vehicle is acquired. The initial state of charge may be obtained from a battery state of charge sensor of the vehicle. The magnitude of the initial state of charge may be used to determine a first charge start time for charging the battery. If the value of the initial state of charge is large (e.g., greater than a threshold), this indicates that the remaining charge of the battery is large, and charging of the battery may begin after a period of time. Otherwise, it means that the remaining capacity of the battery is low, and the battery needs to be charged in a short time or immediately.
In step 13, the engine and/or the power battery of the vehicle is controlled to charge the battery based on the vehicle stop information, the initial state of charge of the battery, and the target state of charge. The initial charge start time (e.g., from tomorrow) and the charge period (e.g., every 7 days) of the battery charge may be set based on the vehicle stop information, the initial state of charge, and the target state of charge. Instead of setting the charging cycle, a charging start time (e.g., a plurality of dates) for charging the battery each time may be calculated using a predetermined algorithm. For different types of vehicles, the battery is charged by different components of the vehicle. If the vehicle is a fuel-powered vehicle, the engine of the vehicle is controlled to start, so that the generator is driven to charge the storage battery. If the vehicle is a hybrid vehicle, the engine of the vehicle may be controlled to start to charge the battery, the battery may be charged by the power battery of the vehicle, or both may be combined. If the vehicle is an electric only vehicle, the battery may be charged by the vehicle's power battery.
According to the method, the engine and/or the power battery of the vehicle can be automatically controlled to charge the storage battery according to the vehicle stopping information, the initial charge state and the target charge state of the storage battery of the vehicle received by the vehicle-mounted networking equipment during long-term stopping of the vehicle, the vehicle does not need to be started manually, and the convenience is greatly improved while the economic loss of a vehicle owner is avoided.
Referring now to FIG. 2, a flow chart of a vehicle shutdown maintenance method according to another embodiment of the invention is shown. In fig. 2, steps 11, 12 and 13 are the same as in fig. 1, and will not be described again here. Only steps 14 and 15 are described below. Although step 14 is shown in fig. 2 as being performed in parallel with step 12 and after step 11, it will be appreciated that step 14 is not sequential to steps 11 and 12 and therefore may be performed in parallel or sequentially, without limitation. In step 14, weather information of the location of the vehicle is received via the in-vehicle networking device. As previously described, the cloud server may determine the geographic location where the vehicle is currently located through communication with the in-vehicle networking device, which may obtain predicted weather information or real-time weather information for the geographic location from the internet, and send the predicted weather information or real-time weather information to the in-vehicle networking device. The predicted weather information may be, for example, predicted weather information during a vehicle stop period. Weather information for the location of the vehicle may be received from the cloud server via the in-vehicle networking device one or more times during the vehicle-stopped period.
In step 15, the air conditioning operation of the vehicle is controlled based on the vehicle stop information, the weather information, and the target cabin humidity of the vehicle to dehumidify the cabin of the vehicle. The first dehumidification time (e.g., from today) and the dehumidification cycle (e.g., every 5 days) for turning on the air conditioner for dehumidification of the cabin may be set based on the vehicle stop information, the weather information, and the target cabin humidity. Instead of setting the dehumidification period, a predetermined algorithm may be used to calculate a start time (e.g., a plurality of dates) for each time the air conditioner is turned on to dehumidify the cabin. Weather information may be used to determine a first dehumidification start time for controlling the air conditioner to be turned on. If the weather is drier for a few days in the future, the air conditioner can be controlled to be started again after the few days or when the weather is wet. Conversely, if there is rainfall for several days in the future, it is necessary to control the air conditioner on for the several days or immediately to dehumidify the cabin. In addition, in other embodiments, the first dehumidification time and the dehumidification period may also be determined in combination with the first charge time and the charge period. For example, if the calculated first charge time is very close to the first dehumidification time, one of the times is taken as the time of both the first charge and the first dehumidification.
According to the method, in addition to being capable of automatically controlling the engine and/or the power battery of the vehicle to charge the storage battery during long-term stopping of the vehicle, the air conditioner operation of the vehicle can be automatically controlled to dehumidify the vehicle cabin according to the vehicle stopping information, the weather information and the target cabin humidity of the vehicle received by the vehicle-mounted networking equipment, the vehicle does not need to be started manually, and the convenience is greatly improved while the economic loss of a vehicle owner is avoided.
Referring now to fig. 3, several sub-steps of step 13 of fig. 1 and 2 are shown. First, step 31 includes determining at least one charging phase of the battery during the vehicle-off period based on the vehicle-off period, the initial state of charge, and the target state of charge. As described above, a plurality of charging cycles in the vehicle stop period may be set, or a charging start time of each charging stage (i.e., charging the battery at a time) may be calculated using a predetermined algorithm instead of the cycle.
Next, step 32 includes controlling an engine and/or a power cell of the vehicle to charge the battery based on the target state of charge during each of the charging phases. The target state of charge may be sent to an Engine Management System (EMS) or a vehicle control system (VCU) that controls the engine and/or the power cells to charge the battery based on a preset control algorithm, such as a PID algorithm.
Referring now to fig. 4-6, several exemplary sub-steps of step 32 of fig. 3 are described for different types of vehicles.
Referring to fig. 4, when the vehicle is a fuel-powered vehicle, in each charging phase, an engine start command is first generated based on the target state of charge and sent to the engine management system of the vehicle in step 41. This target state of charge of the battery may be included in the engine start command. After receiving the engine starting command, the engine management system controls the engine to start and further drives the generator to work so as to charge the storage battery according to the target state of charge and a preset algorithm. Next, in step 42, engine operation information and generator operation information from the engine management system are received, and in step 43, it is determined whether the engine start command is successfully executed based on the engine operation information and the generator operation information. In some cases (e.g., engine failure or fuel starvation) it will be determined that the engine start command was not executed successfully, then in step 44 charge failure information is sent via the in-vehicle networking device. The in-vehicle networking device may send charge failure information to the client device via the cloud server and present to the user.
Referring to fig. 5, when the vehicle is a hybrid vehicle, in each charging phase, the state of charge of the power battery is first acquired in step 51. The state of charge may be obtained from a state of charge sensor of the power cell. Subsequently, in step 52, it is determined whether the power battery has sufficient charge to charge the battery by comparing the state of charge of the power battery with a preset first threshold. If the power battery has sufficient charge, then in step 553, a battery charge command is generated based on the target state of charge and sent to the vehicle control unit of the vehicle. The whole vehicle control unit sends a relay closing command to a Battery Management System (BMS) to control the relay of the power battery to be closed, sends a request working command to the DC-DC converter, and controls the switch from the high-voltage system to the low-voltage system to be closed, so that the power battery of the vehicle is controlled to charge the storage battery. The whole vehicle control unit receives command execution results from the battery management system and the DC-DC converter and state information of a switch from the high-voltage system to the low-voltage system respectively, and judges whether the battery charging command is successfully executed or not and generates an execution result according to the command execution results and the state information of the switch. Thus, step 54 includes receiving an execution result of the battery charge command from the vehicle control unit. If the execution result indicates that the battery charge command was not executed successfully in step 55, in step 56, charge failure information is transmitted via the in-vehicle networking device. Likewise, the in-vehicle networking device may send charge failure information to the client device via the cloud server and present to the user.
If it is determined in step 52 that the amount of power of the power battery is insufficient to charge the battery, step 53' is entered, an engine start command is generated based on the target state of charge and sent to an engine management system of the vehicle to start the engine to charge the battery. Similar to the fuel-powered vehicle, in step 54', engine operation information and generator operation information from the engine management system are received, and in step 55', it is determined whether the engine start command is successfully executed based on the engine operation information and the generator operation information. In some cases (e.g., engine failure or fuel starvation) it will be determined that the engine start command was not executed successfully, then charge failure information is sent via the in-vehicle networking device in step 56.
Referring to fig. 6, when the vehicle is an electric vehicle, in each charging phase, the state of charge of the power battery is first acquired in step 61. The state of charge may also be obtained from a state of charge sensor of the power cell. Subsequently, in step 62, it is determined whether the power cell has sufficient charge to charge the battery by comparing the state of charge of the power cell with a preset first threshold. If the power battery has sufficient charge, then in step 63, a battery charge command is generated based on the target state of charge and sent to the vehicle control unit of the vehicle. The whole vehicle control unit receives command execution results from the battery management system and the DC-DC converter and state information of a switch from the high-voltage system to the low-voltage system respectively, and judges whether the battery charging command is successfully executed or not and generates an execution result according to the command execution results and the state information of the switch. Thus, step 64 includes receiving an execution result of the battery charge command from the vehicle control unit. If the execution result indicates that the battery charge command is not executed successfully in step 65, in step 66, charge failure information is transmitted via the in-vehicle networking device. If it is determined in step 62 that the amount of power in the power battery is insufficient to charge the battery, step 66 is also entered. Likewise, the in-vehicle networking device may send charge failure information to the client device via the cloud server and present to the user. In some embodiments, if it is determined that the power battery is not sufficiently charged in the storage battery, the vehicle-mounted networking device may be turned off after the charging failure information is sent through the vehicle-mounted networking device, so as to further save the power of the storage battery.
Returning to fig. 1, in some embodiments, the vehicle shutdown maintenance method of fig. 1 may further include (not shown in fig. 1): and controlling at least part of the plurality of vehicle-mounted electronic modules of the vehicle to be closed based on the vehicle stopping information. Other vehicle-mounted electronic modules powered by the storage battery besides the vehicle-mounted networking equipment, such as a keyless starting system, an anti-theft system and the like, can be closed, so that the electric quantity of the storage battery is saved, and the charging frequency is reduced.
Moreover, in some embodiments, the vehicle shutdown maintenance method of fig. 1 may further include (not shown in fig. 1): and acquiring the state of health and the internal resistance value of the storage battery, judging whether the storage battery is damaged and/or aged based on the initial state of charge, the state of health and the internal resistance value, and if so, sending storage battery damage and/or aging information through the vehicle-mounted networking equipment. The battery damage and/or aging information may be sent to the client device via the cloud server and presented to the user. In this way, the damage and/or aging condition of the storage battery can be automatically judged, and the user is timely notified when the storage battery is damaged and/or aged.
Referring now to fig. 7, several sub-steps of step 15 of fig. 2 are shown. First, step 71 includes determining at least one dehumidification phase and a target cabin temperature and an air conditioner on-duration for each dehumidification phase during a vehicle off period based on the vehicle off period, weather information, and target cabin humidity. As described above, a plurality of dehumidification periods in the vehicle stop period may be set, or a period may not be set, but the start time of each dehumidification stage (i.e., each time the air conditioner is turned on to dehumidify the cabin) may be calculated using a predetermined algorithm. In addition, the temperature of the target vehicle cabin and the opening time of the air conditioner in each dehumidification stage can be calculated by combining the weather information, the humidity of the target vehicle cabin, the air conditioner parameters and other information.
Next, step 32 includes controlling the engine and/or power battery to power the vehicle's air conditioning control module during each dehumidification phase and controlling the vehicle's air conditioning on and off according to the target cabin temperature and the air conditioning on duration. The temperature of the target cabin and the opening time of the air conditioner can be sent to the air conditioner control module, so that the operation of the air conditioner is controlled.
Referring now to fig. 8-10, several exemplary sub-steps of step 72 of fig. 7 are described for different types of vehicles.
Referring to fig. 8, when the vehicle is a fuel-powered vehicle, in each dehumidification phase, an engine start command is first generated in step 81 and sent to the engine management system of the vehicle. After receiving the engine start command, the engine management system starts the engine to supply power to the air conditioner control module. In step 82, an air conditioner operation command is generated based on the target cabin temperature and the air conditioner on-time period and sent to the air conditioner control module. The air conditioner operation command may include a target cabin temperature and an air conditioner on-time period. And after the air conditioner control module receives the air conditioner operation command, the air conditioner is controlled to be started and closed according to the temperature of the target cabin and the opening time of the air conditioner. Although steps 81 and 82 are shown in fig. 8 as sequential, it should be appreciated that these two steps may be performed in parallel or in reverse order. Next, in step 83, air-conditioning operation information from the air-conditioning control module is received, and in step 84, it is determined whether the execution of the air-conditioning operation command is successful or not, based on the air-conditioning operation information. In some cases, such as failure of the engine or insufficient fuel, failure of the air conditioner, etc., the air conditioner operation information indicates that the air conditioner is not normally turned on or is not turned on for a predetermined period of time, and it will be determined that the air conditioner operation command is not successfully executed, dehumidification failure information is transmitted via the in-vehicle networking device in step 85. The in-vehicle networking device may send the dehumidification failure information to the client device via the cloud server and present to the user.
Referring to fig. 9, when the vehicle is a hybrid vehicle, in each dehumidification phase, first, in step 91, the state of charge of the power battery is acquired. The state of charge may be obtained from a state of charge sensor of the power cell. Subsequently, in step 92, it is determined whether the power battery has sufficient charge to power the air conditioning control module by comparing the state of charge of the power battery with a preset second threshold. If the power battery has sufficient charge, in step 93, an air conditioner power supply command is generated and sent to the vehicle control unit of the vehicle. And the whole vehicle control unit sends a relay closing command to the battery management system so as to control a power battery of the vehicle to supply power for the air conditioner control module. In step 92, if it is determined that the electric quantity of the power battery is insufficient to supply power to the air conditioner control module, step 93' is performed, and an engine start command is generated and sent to an engine management system of the vehicle to start the engine to supply power to the air conditioner control module.
In step 94, an air conditioner operation command is generated based on the target cabin temperature and the air conditioner on-time period and sent to the air conditioner control module. It will be appreciated that steps 93 and 94 may be performed in parallel or may be performed in sequence. In step 95, air conditioner operation information from an air conditioner control module is received. In step 96, it is determined whether the air conditioner operation command is successfully executed according to the air conditioner operation information. If the air conditioner operation command is not successfully executed, dehumidification failure information is transmitted via the in-vehicle networking device in step 97. The in-vehicle networking device may send the dehumidification failure information to the client device via the cloud server and present to the user.
Referring to fig. 10, when the vehicle is an electric vehicle, in each dehumidification stage, first, in step 101, the state of charge of the power battery is acquired. The state of charge may be obtained from a state of charge sensor of the power cell. Then, in step 102, it is determined whether the power battery has sufficient charge to power the air conditioner control module by comparing the state of charge of the power battery with a preset second threshold. If the power battery has sufficient power, in step 103, an air conditioner power supply command is generated and sent to the vehicle control unit of the vehicle. And the whole vehicle control unit sends a relay closing command to the battery management system, so that the power battery of the vehicle is controlled to supply power to the air conditioner control module. In step 104, an air conditioner operation command is generated based on the target cabin temperature and the air conditioner on-time period and sent to the air conditioner control module. It will be appreciated that steps 103 and 104 may be performed in parallel or may be performed in sequence. In step 105, air conditioner operation information from an air conditioner control module is received. In step 106, it is determined whether the air conditioner operation command is successfully executed according to the air conditioner operation information. If the air conditioner operation command is not successfully executed, dehumidification failure information is transmitted via the in-vehicle networking device in step 107. The in-vehicle networking device may send the dehumidification failure information to the client device via the cloud server and present to the user. In step 102, if it is determined that the power of the power battery is insufficient to supply power to the air conditioner control module, step 107 is also performed.
A specific application scenario of the vehicle stop maintenance method according to an embodiment of the present invention is described below with reference to fig. 11. Fig. 11 shows a schematic configuration diagram of the vehicle stop maintenance system according to the embodiment. In this system, the vehicle is a fuel-powered vehicle. Both the client device 111 (e.g., a smart phone) and the vehicle's on-board networking device 113 are capable of communicating with the cloud server 112 via a mobile network. The cloud server 112 determines the current geographic position of the vehicle through communication with the vehicle-mounted networking device 113, acquires the current map and related data from the internet, and judges whether the area of the vehicle is about to be blocked. If cloud server 112 determines that the area in which the vehicle is located is about to be blocked, it sends and presents a message to client device 111 via the display screen, "vehicle will enter blocked mode, is it agreed? ". The user may agree or reject the vehicle to enter the lockout mode by clicking a dialog box on the display screen and may additionally enter the predicted lockout period if agreeing. Alternatively, the lockout period may also be determined by the cloud server 112.
The cloud server 112 acquires predicted weather information during the lockout period from the internet and transmits to the in-vehicle networking device 113 together with the lockout period. The in-vehicle networking device 113 sends a lockout mode command to the body control system 115 via the CAN bus, which includes predicted weather information and lockout time periods. In this lockout mode, the body control system 115 first sends a shutdown command to other on-board electronic modules (e.g., keyless start system, anti-theft system, etc.) in addition to the on-board networking device 113 to conserve battery power. Next, the vehicle body control system 115 acquires the initial state of charge, the state of health, and the internal resistance value of the battery from a battery sensor (not shown in fig. 11) via the LIN bus, determines whether the battery is damaged and/or aged based on the initial state of charge, the state of health, and the internal resistance value, and if it is determined that the battery is damaged and/or aged, transmits battery damage and/or aging information to the in-vehicle networking device 113. The in-vehicle networking device 113 sends this battery damage and/or aging information to the client device 111 via the cloud server 112 and presents it to the user via a display screen. In the present embodiment, if it is determined that the battery is not damaged and/or aged, the vehicle body control system 115 determines an initial charge time and a charge cycle based on the lockout period, the initial state of charge, and the target state of charge of the battery. In addition, the vehicle body control system 115 also determines an initial dehumidification time, a dehumidification cycle, and a target cabin temperature and an air conditioner on-time for each dehumidification based on the lockout period, the predicted weather information, and the target cabin humidity of the vehicle. It will be appreciated that in other embodiments, the initial charge and dehumidification time and charge and dehumidification period may also be determined comprehensively based on the lockout period, the initial state of charge of the battery, the target state of charge, the predicted weather information, and the target cabin humidity of the vehicle, for simplicity of logic. That is, the battery is charged at the same time, and the cabin is dehumidified.
In the present embodiment, at each charge, the vehicle body control system 115 transmits an engine start command including a target state of charge to the engine management system 117 via the CAN bus. After receiving the engine start command, the engine management system 117 controls engine start and sends a load voltage to the generator control module 118 via the LIN bus to control generator operation to charge the battery and send engine operation information and generator operation information to the body control system 115 according to the target state of charge and the preset algorithm. The vehicle body control system 115 determines whether the engine start command is successfully executed based on the engine operation information and the generator operation information. If it is determined that the execution is unsuccessful, the vehicle body control system 115 transmits a charge failure message to the in-vehicle networking device 113. The in-vehicle networking device 113 sends the charge failure message to the client device 111 via the cloud server 112 and presents it to the user via the display screen. After each charging, the vehicle body control system 115 may also send the state of charge of the storage battery after the current charging to the in-vehicle networking device 113. The in-vehicle networking device 113 sends the state of charge to the cloud server 112 and saves it therein for the user to query if needed.
In the present embodiment, at each dehumidification, the vehicle body control system 115 transmits an engine start command to the engine management system 114 via the CAN bus and an air conditioner operation command including a target cabin temperature and an air conditioner on period to the air conditioner control module 116. After receiving the engine start command, the engine management system 114 starts the engine to power the climate control module 116. After receiving the air-conditioning operation command, the air-conditioning control module 116 controls the on and off of the air conditioner according to the target cabin temperature and the air-conditioning on duration, and sends air-conditioning operation information to the vehicle body control system 115. The vehicle body control system 115 determines whether the air-conditioning operation command is successfully executed according to the air-conditioning operation information. If the air-conditioning operation command is not successfully executed, the vehicle body control system 115 transmits a dehumidification failure message to the in-vehicle networking device 113. The in-vehicle networking device 113 sends the dehumidification failure message to the client device 111 via the cloud server 112 and presents it to the user via the display screen.
According to the method, the engine of the vehicle can be automatically controlled to charge the storage battery and control the air conditioner of the vehicle to operate so as to dehumidify the cabin of the vehicle during long-term stopping of the vehicle, the vehicle is not required to be started manually, and the convenience is greatly improved while the economic loss of a vehicle owner is avoided.
