[0090] The following describes the control method, system, after-loading machine and medium of the after-loading machine of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the after-loading machine in the above-mentioned related art takes a long time to start each time, resulting in low efficiency, the present application provides a control method for after-loading machine, in which the vehicle power state is determined by detecting the ignition signal of the target vehicle, and the vehicle machine state is controlled in accordance with the current state of the after-loading machine, so as to achieve the purpose of controlling the vehicle machine to wake up the screen, turn off the screen when in standby mode, and shut down, so that there is no need to restart the vehicle machine every time the vehicle is started, thereby improving the user's efficiency in using the vehicle machine, and can effectively reduce power consumption and extend the battery life of the vehicle machine. As a result, the technical problem that the after-loading machine in the related art takes a long time to start each time, resulting in low efficiency, is solved.

[0091] This application not only improves the comfort and convenience of driving and riding, but also brings car owners a safer and richer car experience through intelligent and personalized functional design.

[0092] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0093] The control method of the rear loader described in the preferred embodiment of the present application is as follows: Figure 2 As shown, the control method of the rear loader includes the following steps:

[0094] In step S101, after the rear loader is connected to a target vehicle, the startup state of the target vehicle and the current state of the rear loader are obtained.

[0095] In a possible implementation, the startup state is one of an ignition signal on state and an ignition signal off state. When it is detected that the target vehicle turns on the vehicle power, the startup state of the target vehicle is determined to be the ignition signal on; when it is detected that the target vehicle turns off the vehicle power, the startup state of the target vehicle is determined to be the ignition signal off.

[0096] Specifically, in the ACC signal detection, when the user turns the key to turn on the vehicle power, the ACC signal is activated (ON state), and the aftermarket vehicle system detects the change of the ACC signal and turns on from the shutdown state or wakes up from the standby state.

[0097] Furthermore, when the driver turns the key or presses the start button, the ACC signal changes (from OFF to ON, or from ON to OFF). The aftermarket machine determines whether the vehicle power is on or off by detecting the state of the ACC signal.

[0098] In the embodiment of the present application, the screen of the after-installed vehicle machine is turned on or off (standby) according to the judgment of ACC (i.e., the power state is judged by the ignition signal state). The screen is on when the vehicle is started within the preset time (such as 2 days), and it can be started without a long time. The vehicle usage scenario is designed with multiple states: normal working state, standby power saving state (screen off state), and shutdown state. The user turns the key to turn on ACC, and the system is turned on from the shutdown state or awakened from the standby state; when the user is using the screen, he can short press the TP virtual power button on the screen to turn off the screen. When long pressing the TP virtual power button, the ACC status needs to be read to distinguish the display; when the user controls the key and turns off ACC, the screen will automatically enter the standby power saving mode after 4 minutes of being on. If there is no wake-up signal from ACC within two days of standby, it will automatically shut down.

[0099] In step S102, a target state of the afterloader is determined according to the startup state and the current state.

[0100] In a possible implementation, the target state includes one of a standby state, a shutdown state, and a working state. When the target vehicle is in the ignition signal on state, the target state is determined to be the working state; when the target vehicle is in the ignition signal off state and the rear loader is in the working state, the target state is determined to be the standby state; when the target vehicle is in the ignition signal off state and the rear loader is in the standby state, the target state is determined to be the shutdown state.

[0101] Specifically, first determine the current state (off state, standby power saving state or normal working state), and decide which state to enter based on the state of the ACC signal (ON or OFF) and the preset time conditions (such as whether there has been an ACC wake-up signal within 2 days). If the system is in the off state and ACC is ON, it will be turned on and enter the normal working state; if the system is in the standby power saving state and ACC is ON, it will be awakened and enter the normal working state; if the system is in the screen-off state and ACC is ON, the screen will be turned on and enter the normal working state.

[0102] In a possible implementation, when the target state is the shutdown state, and the target vehicle maintains the ignition signal off state within the second preset time threshold range, the afterloader is controlled to shut down.

[0103] Specifically, when the user turns off the vehicle power, the ACC signal becomes OFF. After detecting this change in the ACC signal, if the current screen is in the on state, it will automatically enter the standby power saving mode after 4 minutes; in the standby power saving mode, the ACC signal is continuously detected. If there is no ACC wake-up signal within the preset time (such as 2 days), the system will automatically shut down.

[0104] In step S103, the after-loading machine is controlled to display a screen on, off or shut down according to the target state.

[0105] In one possible implementation, if the target state is the working state, the rear loader is awakened to light up the screen; if the target state is the standby state, the rear loader is controlled to turn off the screen at a first preset time threshold; if the target state is the shutdown state, the rear loader is controlled to shut down at a second preset time threshold, wherein the first preset time threshold is less than the second preset time threshold.

[0106] It can be understood that the bright screen indicates the working status of the after-sales vehicle machine, and the off screen includes the standby state and the shutdown state.

[0107] Specifically, power on and wake up: If the ACC signal changes from OFF to ON, and the after-loader is in the shutdown state, the after-loader will start the power on process. If the after-loader is already in the standby power saving state, when the ACC signal changes to ON, the after-loader will be awakened and return to normal working state. Standby and shutdown: When the ACC signal changes from ON to OFF, and the screen remains on for more than the set time (such as 4 minutes), the after-loader will automatically enter the standby power saving mode. In the standby power saving mode, the after-loader will reduce power consumption, but will still monitor the ACC signal. If in the standby power saving mode, the ACC signal does not turn ON again within the set time (such as 2 days), the after-loader will automatically shut down.

[0108] This application reduces the startup time of the aftermarket machine and improves the user's efficiency by turning on or off the screen according to the ACC power status. The standby power saving mode and automatic shutdown function effectively reduce power consumption and extend battery life.

[0109] In one possible implementation, when the rear loader is in the working state, in response to a screen-off operation for the rear loader, a screen-off instruction corresponding to the screen-off operation is identified, and according to the screen-off instruction, the rear loader is controlled to switch to the standby state; when the target vehicle is in the ignition signal-on state, in response to a screen-on operation for the rear loader, a screen-on instruction corresponding to the screen-off operation is identified, and according to the screen-on instruction, the rear loader is controlled to switch to the working state.

[0110] Specifically, under normal working conditions, users can use the screen to perform various operations. Users can short press the TP virtual power button on the screen to turn off the screen. At this time, the screen is turned off but the system is still in standby mode. When the user long presses the TP virtual power button, the system will read the ACC status again. If ACC is ON, the screen will light up and enter normal working state. If ACC is OFF, the current state will be maintained or other preset operations will be performed (such as entering standby power saving state).

[0111] That is, under normal working conditions, the afterloader will keep the screen on. If the user short presses the TP virtual power button during screen operation, the screen will enter the off state, but the afterloader will remain powered on. If the user long presses the TP virtual power button during screen operation, the system needs to read the current ACC status. If ACC is ON, relevant menus or options may be displayed; if ACC is OFF, a specific shutdown or standby process may need to be performed.

[0112] In a possible implementation, when the rear loader is in the working state, a reversing signal of the target vehicle is acquired; and according to the reversing signal, the rear loader is controlled to display a reversing image on a screen.

[0113] The embodiment of the present application is aimed at the large screen of the after-installed vehicle machine, and the diagnostic signals based on it are only the ACC signal (ignition signal) and the reversing signal. Compared with the front-installed CAN and Ethernet signals, it will have more enriched functions.

[0114] Next, the control system of the after-loader proposed in accordance with the embodiment of the present application will be described with reference to the accompanying drawings.

[0115] Figure 3 It is a structural diagram of the control system of the after-loader according to an embodiment of the present application.

[0116] like Figure 4 As shown, the control system of the after-loader includes: a state acquisition module 100, a state determination module 200 and an execution module 300.

[0117] Specifically, the state acquisition module 100 is used to acquire the startup state of the target vehicle and the current state of the rear loader after the rear loader is connected to the target vehicle;

[0118] A state determination module 200, for determining a target state of the rear loader according to the startup state and the current state;

[0119] The execution module 300 is used to control the aftermarket machine to display a screen on, turn off the screen, or shut down the machine according to the target state.

[0120] Figure 4This is a structural diagram of a rear loader provided in an embodiment of the present application. The rear loader may include:

[0121] A memory 501 , a processor 502 , and a computer program stored in the memory 501 and executable on the processor 502 .

[0123] Furthermore, the afterloader also includes:

[0125] The memory 501 is used to store computer programs that can be executed on the processor 502 .

[0126] The memory 501 may include a high-speed RAM memory, and may also include a non-volatile memory (non-volatile memory), such as at least one disk memory.

[0127] If the memory 501, the processor 502 and the communication interface 503 are implemented independently, the communication interface 503, the memory 501 and the processor 502 can be connected to each other through a bus and communicate with each other. The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component (PCI) bus or an Extended Industry Standard Architecture (EIS) bus. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 4 Only one thick line is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0128] Optionally, in a specific implementation, if the memory 501, the processor 502 and the communication interface 503 are integrated on a chip, the memory 501, the processor 502 and the communication interface 503 can communicate with each other through an internal interface.

[0129] The processor 502 may be a central processing unit (CPU), or an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application.
