BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0031] Figure 2 Schematic diagram of a vehicle power supply control device in an embodiment of the present invention. DETAILED DESCRIPTION

[0032] The embodiments of the present invention solve the technical problem of short battery life of external power supply equipment of vehicles in the prior art by providing a vehicle power supply control method and device.

[0033] In order to better understand the technical solution of the present invention, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] like Figure 1As shown, the vehicle power supply control method of this embodiment includes:

[0035] Step S1, obtaining the actual power of the vehicle's small battery and the actual state of the vehicle's external power supply interface;

[0036] Step S2, if the actual power level is lower than the preset threshold and the actual state is the target state, the target state indicates that the external power supply interface is connected to an external power supply device, then the external power supply device is controlled to supply power to at least one of the vehicle's emergency components and the central control screen, the external power supply device is cut off from supplying power to the vehicle's non-emergency components, and the application software in the central control screen that controls the non-emergency components is closed.

[0037] The method of this embodiment is applicable to vehicles whose parts are all electronically controlled, that is, vehicles that control various emergency and non-emergency parts through buttons on the central control screen. The external power supply device can be a modified mobile phone that can power the vehicle, and the external power supply interface can be a Type-C interface. In step S2, the actual power of the vehicle's small battery is lower than the preset threshold, indicating that the small battery is in a low-power state, and the preset threshold can be 10%; the actual state of the external power supply interface is the target state, which means that the mobile phone is connected to the Type-C interface on the vehicle through a wiring harness, so that the mobile phone can power the vehicle instead of the small battery.

[0038] Emergency vehicle parts may include one or more of a fault light, a charging cover, a trunk cover, etc. Non-emergency parts may include a Tbox, a driving recorder, etc. When a small battery runs out of power, the vehicle cannot be driven, and users often need to turn on the fault light to warn other passing vehicles, open the charging cover for charging, open the trunk to take out a warning sign or other items, etc.

[0039] By default, all application software in the central control screen are kept running in the background and will consume power. After the central control screen and an emergency component are powered on in step S2, and the application software that controls the emergency component in the central control screen is not closed, the user can control the emergency component through the application software that controls the emergency component on the central control screen, thereby realizing the user's emergency operation in an emergency. It can be understood that cutting off the power supply of the vehicle's non-emergency components by the external power supply equipment can save the power consumption of non-emergency components, and shutting down the application software that controls non-emergency components in the central control screen can reduce the power consumption of non-emergency application software. Reducing the power consumption of the vehicle's electrical components from two aspects can increase the battery life of the external power supply equipment.

[0040] In step S2, controlling the external power supply device to supply power to at least one of the emergency components may include: controlling the external power supply device to supply power to all emergency components simultaneously, so that the user can control the action of any emergency component through the central control screen.

[0041] It is understandable that supplying power to all emergency components at the same time and keeping all application software that controls emergency components running will still result in high power consumption of emergency components and emergency application software, which is not conducive to saving power. Considering that for emergency components such as the charging cover and the trunk lid, power is consumed only when the charging cover and the trunk lid are controlled to be opened, and after the charging cover and the trunk lid are opened, the maintenance or closing of the open state can be achieved without consuming power, it is possible to choose to cut off the power supply and close the corresponding application software after these emergency components are opened to save power. To this end, in step S2, after controlling the external power supply device to supply power to all emergency components at the same time, controlling the external power supply device to supply power to at least one of the emergency components can also include: obtaining the status of a type of component in the emergency components; if the status of a type of component is an open state, cutting off the power supply of the external power supply device to the type of component, and closing the application software that controls the type of component in the central control screen. Among them, one category of components may include one or both of the charging cover and the trunk cover, and the second category of components may include a fault light. Since turning on the fault light, keeping the fault light on, and turning off the fault light all require power or running application software, the fault light needs to be powered on and the application software that controls the fault light needs to be running during the entire process.

[0042] In this embodiment, in order to reduce the power consumption of emergency components and emergency application software, in step S2, the external power supply device is controlled to power at least one of the emergency components, and it can also include: according to the priority of a category of components in the emergency components, the external power supply device is controlled to power a category of components in turn, when the external power supply device supplies power to a category of components, the application software that controls the category of components in the central control screen is started, and the application software that controls all other categories of components in the central control screen is closed. For example, when a small battery runs out of power, the fault light should be turned on immediately, and the second is to consider opening the charging cover to charge. The priority of such a type of parts is the charging cover and the trunk cover. First, control the external power supply device to supply power to the charging cover and cut off the power supply to the trunk cover, start the application software that controls the charging cover in the central control screen and close the application software that controls the trunk cover for 1 minute. During this 1 minute, the user can open the charging cover through the central control screen; then control the external power supply device to supply power to the trunk cover and cut off the power supply to the charging cover, start the application software that controls the trunk cover in the central control screen and close the application software that controls the charging cover for 1 minute. During this 1 minute, the user can open the trunk cover through the central control screen; repeat the above process. This can not only ensure the user's need to open any type of parts, but also reduce the power consumption of emergency parts and emergency applications.

[0043] like Figure 2 As shown, this embodiment also provides a vehicle power supply control device, including:

[0044] An acquisition module is used to obtain the actual power of the vehicle's small battery and the actual status of the vehicle's external power supply interface;

[0045] The control module is used to control the external power supply device to supply power to at least one of the vehicle's emergency components and the central control screen if the actual power level is lower than a preset threshold and the actual state is a target state, and the target state indicates that the external power supply interface is connected to an external power supply device, and then cut off the power supply of the external power supply device to the vehicle's non-emergency components, and close the application software that controls the non-emergency components in the central control screen.

[0046] Furthermore, the control module can also be used to control the external power supply device to supply power to all emergency components at the same time.

[0047] Furthermore, the acquisition module can also be used to obtain the status of a type of components in the emergency components; the control module is also used to cut off the power supply of the type of components to the external power supply equipment if the status of the type of components is open, and close the application software that controls the type of components in the central control screen.

[0048] Furthermore, the control module can also be used to control the external power supply equipment to supply power to a class of components in sequence according to the priority of a class of components among emergency components. When the external power supply equipment supplies power to a class of components, the application software that controls the class of components in the central control screen is started, and the application software that controls all other classes of components in the central control screen is closed.
