[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] In the embodiment of the present application, the inventor proposes a charging method, device and vehicle, when the vehicle is in a dormant state, the vehicle control module of the vehicle is awakened at a fixed time, the vehicle control module awakens the charging control module, the charging control module monitors the remaining power of the vehicle's movable on-board equipment, and when the remaining power is less than a first threshold, the vehicle control module charges the movable on-board equipment. Through the above-mentioned method, when the vehicle is in a dormant state, the vehicle control module of the vehicle can be awakened at a fixed time; the vehicle control module awakens the charging control module; the charging control module monitors the remaining power of the vehicle's movable on-board equipment; when the remaining power is less than the first threshold, the vehicle control module charges the movable on-board equipment, wherein when the vehicle is in a dormant state, the vehicle control module and the charging control module are awakened regularly, the remaining power of the movable on-board equipment can be monitored, and when the remaining power is lower than the first threshold, the movable on-board equipment is charged, thereby avoiding the situation where the user wants to use the movable on-board equipment next time and the user experience is poor due to low power.

[0018] See also Figure 1 , an embodiment of the present application provides a charging method, the method comprising:

[0019] S110: When the vehicle is in a dormant state, waking up the vehicle control module of the vehicle at a scheduled time.

[0020] The vehicle being in a dormant state can be understood as the vehicle's entire power supply being off, and all components of the vehicle being in a dormant state, that is, all components of the vehicle are not performing any tasks.

[0021] The vehicle control module can be used for timing polling and charging control when the vehicle is dormant, and the vehicle control module can be a VCU (Vehicle Control Unit).

[0022] As a method, when the vehicle is in sleep mode, the vehicle control module can be woken up at a scheduled time.

[0023] Exemplarily, the timing duration can be 24 hours. When the vehicle is in a dormant state, the timer can be started. After 24 hours from the start of the vehicle being in a dormant state, the vehicle control module can be awakened. After the vehicle control module is awakened, the timer can be cleared and reset. If the vehicle is always in a dormant state within the next 24 hours, the vehicle control module can be awakened again after 48 hours from the start of the vehicle being in a dormant state. In other words, when the vehicle is in a dormant state, the vehicle control module can be awakened periodically.

[0024] It should be noted that when the vehicle control module is awakened, since the vehicle control module is in a non-sleeping state, the vehicle also exits the sleeping state and switches to a non-sleeping state.

[0025] S120: The vehicle control module wakes up the charging control module.

[0026] As a way, after the vehicle control module is awakened, the vehicle control module can wake up the charging control module, the movable vehicle-mounted equipment, the body control module and the battery.

[0027] Among them, Figure 2 As shown, a charging control system 10 may be provided in the vehicle, and the charging control system 10 may include a vehicle 100 and a movable vehicle-mounted device 200 , wherein the vehicle 100 may include a vehicle control module 102 , a charging control module 104 , a body control module 106 , an energy output module 108 , and a battery 110 .

[0028] The charging control module 104 can be used to monitor the power status of the mobile vehicle-mounted device 200, control the charging of the mobile vehicle-mounted device 200, send a charging request to the body control module 106, and receive the power output by the battery 110. The charging control module 104 can include a variety of sensors, so as to adjust the charging current and voltage according to the information fed back by the sensors, so as to charge the mobile vehicle-mounted device 200 under safe conditions.

[0029] The body control module (Body Control Module, BCM) 106 can be used to monitor the power status of the whole vehicle and send the power status of the whole vehicle to the charging control module 104, control the power output of the battery 110, and forward the charging request received from the charging module 104 to the vehicle control module 102.

[0030] The energy output module 108 can be used to recharge the battery 110. When the vehicle is a fuel vehicle, the energy output module 108 can be an engine management system (EMS); when the vehicle is an electric vehicle, the energy output module 108 can be a battery management system (BMS).

[0031] The movable vehicle-mounted device 200 may be a vehicle-mounted drone, a game console, an entertainment tablet computer, etc.

[0032] Optionally, the charging control module 104 may charge the movable vehicle-mounted device 200 by wired charging or wireless charging.

[0033] It should be noted that when the charging method corresponding to the mobile vehicle-mounted device 200 is wired charging, the mobile vehicle-mounted device 200 needs to be connected to the vehicle 100 through a charging cable so that when the vehicle is in a dormant state, the vehicle control module 102 can wake up the mobile vehicle-mounted device 200. When the charging method corresponding to the mobile vehicle-mounted device 200 is wireless charging, the mobile vehicle-mounted device 200 needs to be connected to the vehicle 100 through a wireless charging seat so that when the vehicle is in a dormant state, the vehicle control module 102 can wake up the mobile vehicle-mounted device 200. That is to say, in the embodiment of the present application, the basic condition for the present application to charge the mobile vehicle-mounted device 200 is that the hardware modules between the vehicle 100 and the mobile vehicle-mounted device 200 are interconnected. Once the vehicle control module, the charging control module, the mobile vehicle-mounted device, the body control module and the battery are awakened one after another, a path can be formed, so that the remaining power and other information of the mobile vehicle-mounted device 200 can be obtained.

[0034] S130: The charging control module monitors the remaining power of the movable on-board equipment of the vehicle.

[0035] As a method, the charging control module can monitor the remaining power of the mobile vehicle device by receiving the remaining power fed back by the awakened mobile vehicle device.

[0036] S140: When the remaining power is less than a first threshold, the vehicle control module charges the movable vehicle-mounted device.

[0037] As a method, when the charging control module confirms that the remaining power is less than the first threshold, the charging control module can send a charging request to the vehicle control module through the body control module; after receiving the charging request, the vehicle control module controls the battery to charge the movable vehicle-mounted device.

[0038] The charging request may refer to a request for requesting the battery to output electric energy to the charging control module. The charging request may be a primary charging request or a secondary charging request, and the primary charging request has a lower demand on vehicle electric energy than the secondary charging request.

[0039] In some embodiments, when the charging control module confirms that the remaining power is less than a first threshold and greater than a second threshold, the charging control module can send a first-level charging request to the vehicle control module through the body control module; after receiving the first-level charging request, the vehicle control module controls the battery to charge the movable vehicle-mounted device.

[0040] The first threshold is greater than the second threshold, and the first threshold and the second threshold of different movable vehicle-mounted devices may be different.

[0041] Optionally, the first threshold and the second threshold may be determined according to the power consumption speed of the mobile vehicle device. The faster the power consumption speed of the mobile vehicle device is, the higher the first threshold and the second threshold may be. Exemplarily, if the power consumption speed of the mobile vehicle device A is greater than that of the mobile vehicle device B, then the first threshold of the mobile vehicle device A is greater than the first threshold of the mobile vehicle device B, and the second threshold of the mobile vehicle device A is greater than the second threshold of the mobile vehicle device B.

[0042] Optionally, the first threshold and the second threshold may be determined according to the frequency with which the mobile vehicle-mounted device is used by the user. The higher the frequency of use of the mobile vehicle-mounted device, the higher the first threshold and the second threshold may be. Exemplarily, if the frequency of use of the mobile vehicle-mounted device A is higher than that of the mobile vehicle-mounted device B, then the first threshold of the mobile vehicle-mounted device A is greater than the first threshold of the mobile vehicle-mounted device B, and the second threshold of the mobile vehicle-mounted device A is greater than the second threshold of the mobile vehicle-mounted device B.

[0043] Optionally, after receiving the first-level charging request, the vehicle control module controls the battery to output power to the charging module, and controls the charging module to charge the movable vehicle-mounted equipment.

[0044] In the embodiment of the present application, since the battery is only awakened at this time and does not output electric energy to the charging control module, in order to ensure the continuity of charging and to have sufficient power so that the remaining power of the movable vehicle-mounted equipment can be charged to the first threshold and above, it is necessary to control the battery to output electric energy to the charging control module, so the charging control module can send a first-level charging request at this time.

[0045] In some embodiments, when the charging control module confirms that the remaining power is less than a second threshold, the charging control module can send a secondary charging request to the vehicle control module through the body control module; after receiving the secondary charging request, the vehicle control module can control the energy output module to recharge the battery and control the battery to charge the movable vehicle-mounted equipment.

[0046] Optionally, after receiving the secondary charging request, the vehicle control module can also control the battery to output electrical energy to the charging module, and control the charging module to charge the movable vehicle-mounted equipment.

[0047] In an embodiment of the present application, since the remaining power of the mobile vehicle-mounted equipment is too low, more power is required to charge it to the first threshold or above. Therefore, in order to ensure the continuity of charging and avoid battery depletion, it is necessary to control the energy output module to replenish the battery, so the charging control module can send a secondary charging request at this time.

[0048] Optionally, within the first preset time after the charging control module initiates a charging request, if the battery does not output power to the charging module, the charging module can stop charging the movable vehicle-mounted device and put the vehicle into a dormant state. This can avoid the charging control module continuously initiating charging requests due to battery abnormalities or power / high voltage abnormalities, thereby preventing the vehicle from being able to go into dormancy.

[0049] The first preset time may be based on a preset value obtained through multiple tests.

[0050] Optionally, within the first preset time after the charging control module initiates a charging request, if the battery does not output power to the charging module, the charging module can stop charging the movable vehicle-mounted device and put the vehicle into a dormant state. This can avoid the charging control module continuously initiating charging requests due to battery abnormalities or power / high voltage abnormalities, thereby preventing the vehicle from being able to go into dormancy.

[0051] Optionally, after the charging control module initiates the secondary charging request for a third preset time (that is, the duration of continuous charging for the mobile vehicle device is the duration corresponding to the third preset time), the charging module can stop charging the mobile vehicle device. This can avoid the vehicle being in a power-consuming state due to abnormalities in the charging control module (such as: failure to sense the remaining power of the mobile vehicle device, etc.) or abnormalities in the mobile vehicle device (such as: failure to charge, abnormal feedback of the remaining power, etc.).

[0052] The third preset time may refer to the time required for the charging control module to charge the remaining power of the mobile vehicle-mounted device from 0 to the first threshold.

[0053] Optionally, after the charging control module charges the mobile vehicle device, it can continue to monitor the remaining power of the mobile vehicle device. When the remaining power of the mobile vehicle device is greater than or equal to the first threshold, it can stop charging the mobile vehicle device and re-enter the sleep state.

[0054] Optionally, when the charging control module confirms that the remaining power is greater than or equal to the first threshold, it may not send any charging request to the vehicle control module. At the same time, the vehicle control module may start timing after being awakened. If no charging request is received after a preset period of time, the vehicle may be put back into sleep mode.

[0055] Optionally, when the charging control module confirms that the remaining power is greater than or equal to the first threshold, the charging control module can send a sleep request to the vehicle control module. After receiving the sleep request, the vehicle control module puts the vehicle back into sleep mode.

[0056] This embodiment provides a charging method, when the vehicle is in a dormant state, the vehicle control module of the vehicle is awakened at a fixed time, the vehicle control module awakens the charging control module, the charging control module monitors the remaining power of the vehicle's movable on-board equipment, and when the remaining power is less than a first threshold, the vehicle control module charges the movable on-board equipment. Through the above method, when the vehicle is in a dormant state, the vehicle control module of the vehicle can be awakened at a fixed time; the vehicle control module awakens the charging control module; the charging control module monitors the remaining power of the vehicle's movable on-board equipment; when the remaining power is less than the first threshold, the vehicle control module charges the movable on-board equipment, wherein when the vehicle is in a dormant state, the vehicle control module and the charging control module are awakened periodically, the remaining power of the movable on-board equipment can be monitored, and when the remaining power is lower than the first threshold, the movable on-board equipment is charged, thereby avoiding the situation where the user wants to use the movable on-board equipment next time and the user has a poor user experience due to low power.

[0057] See also Figure 3 , an embodiment of the present application provides a charging method, the method comprising:

[0058] S210: When the vehicle is in a dormant state, periodically wake up the vehicle control module of the vehicle.

[0059] S220: The vehicle control module wakes up the charging control module.

[0060] S230: The charging control module monitors the remaining power of the movable on-board equipment of the vehicle.

[0061] S240: When the remaining power is less than a first threshold, the vehicle control module charges the movable vehicle-mounted device.

[0062] S250: When the vehicle is not in a dormant state, the charging control module monitors the remaining power of the movable vehicle-mounted device.

[0063] Among them, the vehicle is not in a dormant state and can include the following two situations. The first is that the power state of the entire vehicle is on (ON) and the user is using the vehicle; the second is that the user has just left the vehicle, during which time the power state of the entire vehicle can be switched from on to off (OFF).

[0064] In the embodiment of the present application, the second situation is mainly discussed. Therefore, from the perspective of the relationship between the user and the vehicle, when the vehicle is not in a dormant state, it can indicate that the user has just left the vehicle, and when the vehicle is in a dormant state, it can indicate that the user has been away from the vehicle for a period of time (possibly a few minutes, a few days, or even a few weeks).

[0065] As a method, the charging control module can monitor the remaining power of the removable vehicle-mounted device when the vehicle is not in a dormant state.

[0066] Optionally, when the vehicle is not in a dormant state, the charging control module can also monitor the power status of the entire vehicle.

[0067] Optionally, when the vehicle is not in sleep mode, the body control module may periodically poll the power status of the vehicle and send the polling results to the charging control module.

[0068] It should be noted that when the vehicle control module starts to charge the movable vehicle-mounted device through steps S210 to S240, it can be equivalent to the vehicle changing from a sleep state to a dormant state. That is to say, after the vehicle control module starts to charge the movable vehicle-mounted device, the charging control module can monitor the remaining power of the movable vehicle-mounted device and perform subsequent steps S260 to S280 based on the remaining power of the movable vehicle-mounted device.

[0069] S260: If the remaining power of the movable vehicle-mounted device is greater than the second threshold and less than the first threshold, the charging control module sends a first-level charging request to the body control module of the vehicle.

[0070] As a method, within a polling cycle of the body control module, if the power status of the entire vehicle is off and the remaining power of the movable vehicle-mounted device is greater than the second threshold and less than the first threshold, the charging control module can send a first-level charging request to the body control module of the vehicle.

[0071] S270: After receiving the first-level charging request, the body control module controls the battery of the vehicle to start charging the movable vehicle-mounted device.

[0072] As a method, the body control module can control the battery to start charging the removable vehicle-mounted device after receiving a first-level charging request.

[0073] Optionally, after receiving the first-level charging request, the body control module can control the battery to output electrical energy to the charging module, and control the charging module to charge the movable vehicle-mounted device, so that there is sufficient electrical energy to charge the remaining power of the movable vehicle-mounted device to the first threshold or above.

[0074] S280: After a second preset time, the body control module controls the battery to stop charging the movable vehicle-mounted device and puts the vehicle into a dormant state.

[0075] The second preset time may refer to the time required to charge the remaining power of the mobile vehicle-mounted device to the first threshold value. The second preset time may be obtained based on multiple test results, and different remaining powers may correspond to different second preset times.

[0076] As a method, after controlling the battery to charge the movable vehicle-mounted device, after a second preset time has passed, the body control module can control the battery to stop charging the movable vehicle-mounted device and put the vehicle into a dormant state.

[0077] Optionally, after executing step S250, if the remaining power of the movable vehicle-mounted device is less than or equal to the second threshold, the charging control module sends a secondary charging request to the body control module of the vehicle; after receiving the secondary charging request, the body control module controls the battery to charge the movable vehicle-mounted device, and controls the vehicle control module of the vehicle to replenish the battery.

[0078] Optionally, within a polling cycle of the body control module, if the power state of the vehicle is off and the remaining power of the movable vehicle-mounted device is less than or equal to the second threshold, the charging control module can send a secondary charging request to the body control module of the vehicle. The body control module can send the secondary charging request to the vehicle control module; when the vehicle is an electric vehicle, after receiving the secondary charging request, the vehicle control module controls the vehicle's power battery to recharge the battery; when the vehicle is a fuel vehicle, after receiving the secondary charging request, the vehicle control module controls the vehicle's engine to recharge the battery.

[0079] Optionally, during the charging of the portable vehicle-mounted device, the temperature of the built-in battery of the portable vehicle-mounted device can be monitored in real time. If the temperature is higher than a preset temperature during the current polling cycle, the portable vehicle-mounted device can be not charged during the current polling cycle; if the temperature is not higher than a preset temperature during the current polling cycle, the portable vehicle-mounted device can be charged during the current polling cycle, thereby avoiding abnormalities in the portable vehicle-mounted device due to excessively high battery temperature.

[0080] Optionally, during the charging of movable vehicle-mounted devices, the body control module can continue to periodically poll the power status of the entire vehicle and send the power status of the entire vehicle to the charging control module, so that the charging control module can timely adjust the charging strategy, such as stopping charging, changing from a secondary charging request to a primary charging request, etc., thereby reducing the vehicle's own energy output as much as possible and improving the vehicle's own safety.

[0081] Optionally, within a polling cycle of the body control module, if the power status of the entire vehicle is on, the charging control module can continue to charge the movable vehicle-mounted device.

[0082] Optionally, within a polling cycle of the body control module, if the power status of the entire vehicle is off and the remaining power is greater than or equal to a first threshold, the vehicle can be put into a sleep state.

[0083] The present embodiment provides a charging method, through the above-mentioned method, when the vehicle is in a dormant state, the vehicle control module of the vehicle can be awakened at regular intervals; the vehicle control module awakens the charging control module; the charging control module monitors the remaining power of the vehicle's movable on-board equipment; when the remaining power is less than the first threshold, the vehicle control module charges the movable on-board equipment, wherein when the vehicle is in a dormant state, the vehicle control module and the charging control module are awakened regularly, the remaining power of the movable on-board equipment can be monitored, and when the remaining power is lower than the first threshold, the movable on-board equipment is charged, thereby avoiding the situation where the user wants to use the movable on-board equipment next time and the user experience is poor due to low power. In addition, in the present embodiment, when the vehicle is not in a dormant state, the charging control module can determine whether the movable on-board equipment needs to be charged according to the vehicle power supply state and the remaining power of the movable on-board equipment, so that the remaining power of the movable on-board equipment is maintained at a high power level while ensuring that the impact on the vehicle power supply system is small.

[0084] See also Figure 4 The present application provides a charging device 400, the device 400 comprising:

[0086] The charging unit 420 is used for the charging control module to monitor the remaining power of the movable on-board device of the vehicle; when the remaining power is less than a first threshold, the vehicle control module charges the movable on-board device.
