An embodiment of the present invention provides a method for controlling an electric back door of a vehicle, which is applied between a vehicle-mounted terminal, a PLGM, and a support bar motor, as shown in fig. 3, and the method includes:
step 201: the vehicle-mounted terminal displays a setting interface, and obtains the opening height of the electric back door of the vehicle, which is set in the setting interface by a user.
In the embodiment of the invention, the vehicle-mounted terminal can display the setting interface to the user, and the user can set the opening height of the electric back door of the vehicle in the setting interface, so that the vehicle-mounted terminal can acquire the opening height of the electric back door set in the setting interface by the user.
Wherein, can also set up a height setting button in this vehicle mounted terminal, when the user need set up the height of opening of electronic back tail-gate, the user can be through triggering this height setting button, and vehicle mounted terminal detects this height setting button when being triggered, generates the height and sets up the instruction to according to this height setting button, show the setting interface.

In one possible design, when the vehicle-mounted terminal detects that the user opens the electric back door for the first time, the vehicle-mounted terminal can display a prompt message for prompting the user whether to set the opening height of the electric back door in a display screen, wherein the prompt message comprises a confirmation button and a cancel button; the user can select to set the opening height of the electric back door through the confirmation button, and the user can refuse to set the opening height of the electric back door through the cancel button. When the vehicle-mounted terminal detects that the confirmation button is triggered, the vehicle-mounted terminal determines that the user selects and sets the opening height of the electric back door, and then generates a height setting instruction, so that a setting interface is displayed according to the height setting instruction.
And when the vehicle detects that the cancel button is triggered, determining that the user selects to refuse to set the opening height of the electric back door, and ending.
Therefore, in this step, before the vehicle-mounted terminal displays the setting interface, it may be further detected whether there is a height setting instruction in the vehicle-mounted terminal, and this step may be: and whether the vehicle-mounted terminal detects a height setting instruction or not, and when the vehicle-mounted terminal detects the height setting instruction, executing the step that the vehicle-mounted terminal displays the setting interface.
This step can be implemented by the following step 2011-2013.
Step 2011: the vehicle-mounted terminal displays a setting interface, the setting interface displays a vehicle image of the vehicle, and the vehicle image is an image when the electric back door rises to the maximum opening height.
In this step, the vehicle-mounted terminal can display a setting interface for setting the opening height of the electric back door in the display screen, and the vehicle-mounted terminal acquires a vehicle image when the electric back door of the vehicle rises to the maximum opening height and displays the vehicle image in the setting interface of the display screen.
Step 2012: the vehicle-mounted terminal acquires the dragging height for dragging the electric back door on the vehicle image.
In this step, when the user views the vehicle image in the setting interface, the user can set the opening height of the electric back door by manually dragging the electric back door in the vehicle image according to the requirement; when the vehicle-mounted terminal detects that the electric back door is not dragged within the preset time, the vehicle-mounted terminal acquires the dragged height of the electric back door, and the dragged height of the electric back door is used as the dragged height of the electric back door.
The preset duration may be set and changed according to a user requirement, which is not specifically limited in the embodiment of the present invention. For example, the preset time period may be 1 second, 3 seconds, or the like.
Step 2013: and the vehicle-mounted terminal determines the opening height of the electric rear tail gate according to the dragging height and the maximum opening height.
In this step, the dragging height is a dragged height of the electric back door when the user drags the electric back door, and therefore, the vehicle-mounted terminal determines the opening height of the electric back door according to the maximum opening height and the dragging height.
The representation modes of the dragging height, the opening height and the maximum opening height may be set and changed according to the user requirement, which is not specifically limited in the embodiment of the present invention. For example, the opening height may be represented by a distance between the power tailgate and a horizontal ground, or an angle between the power tailgate and a horizontal ground.
For example, the maximum opening height may be represented by an angle between the electric back door and the horizontal ground when the electric back door is raised to the maximum opening height, and the angle between the electric back door and the horizontal ground is taken as a first angle; the dragging height is an angle between the electric back door at the current position and the electric back door at the maximum opening height after the user drags the electric back door, and the angle is used as a second angle; the opening height of the electric back door is the difference between the first angle and the second angle.
The opening height may be set and changed according to a user's requirement, which is not specifically limited in the embodiment of the present invention. For example, the opening height may be 1.2 meters, 1.4 meters, etc.
Step 202: and the vehicle-mounted terminal sends the opening height to the PLGM through a CAN bus.
In the embodiment of the invention, the PLGM is used for controlling the electric back door, and the vehicle-mounted terminal and the PLGM are communicated through the CAN bus, so that the vehicle-mounted terminal sends the opening height to the PLGM through the CAN bus after determining the opening height of the electric back door.
Step 203: the PLGM receives the opening height through the CAN bus and stores the opening height.
In this step, the PLGM receives the opening height sent by the vehicle-mounted terminal through the CAN bus, and stores the opening height so as to directly obtain the opening height from the memory module when the electric back door is opened next time.
Wherein, the PLGM may store the opening height in a memory module of the PLGM or a memory space of the in-vehicle terminal. The embodiment of the present invention is not particularly limited thereto.
Step 204: when the PLGM detects opening of the power tailgate, the PLGM obtains the opening height.
In this step, the PLGM acquires the opening height set by the user only when detecting that the electric back door is opened, and therefore, before this step, the PLGM needs to determine whether the user currently opens the electric back door.
In the embodiment of the invention, a first opening button for opening the electric back door can be arranged in the vehicle-mounted terminal, and a user can open the electric back door by triggering the first opening button; the electric rear tail door can be further provided with a second opening button, and a user can open the electric rear tail door by triggering the second opening button; the electric rear tail door is provided with a kick sensor, and a user can open the electric rear tail door in a mode of kicking the electric rear tail door.
Therefore, the step of the PLGM determining whether the user currently opens the electric back door may be: the PLGM detects whether a first opening button in the vehicle-mounted terminal is triggered or not, detects whether a second opening button on the electric back door is triggered or not, and detects whether a kick sensor of the electric back door is triggered or not. When the PLGM detects that the first open button is triggered, or the second open button is triggered, or the kick sensor is triggered, the PLGM determines to open the power tailgate.
Specifically, when the vehicle-mounted terminal detects that a first opening button in the vehicle-mounted terminal is triggered, the vehicle-mounted terminal generates an opening instruction for opening the electric back door, sends the opening instruction to the PLGM through the CAN bus, receives the opening instruction sent by the vehicle-mounted terminal through the CAN bus, and determines to open the electric back door.
It should be noted that, when the electric back door is in a closed state, the supporting rod point for controlling the opening or closing of the electric back door is in a standby state, and when the second opening button on the electric back door is triggered or the kick sensor of the electric back door is triggered, the supporting rod motor starts to enter a working state.
In the embodiment of the invention, the PLGM can be connected with the support rod motor through the wire harness, so that when the support rod motor starts to enter a working state, the support rod motor can send an acquisition request to the PLGM through the wire harness, and the PLGM receives the acquisition request of the support rod motor through the wire harness and determines to open the electric back door.
The obtaining request may be a request for obtaining a rotation duration.
When the PLGM determines that the user opens the power tailgate, the PLGM retrieves the opening height from a memory module directly from the PLGM.
Step 205: and the PLGM controls the electric back door to ascend to the opening height according to the opening height.
In the embodiment of the invention, the PLGM controls the opening or closing of the electric rear door through a support rod motor.
Specifically, this step can be realized by the following steps 2051-2053.
Step 2051: and the PLGM determines the rotation time of the support rod motor according to the opening height and the rotating speed of the support rod motor.
In this step, the PLGM calculates the work to be done by the support bar motor when the electric back door is opened to the opening height according to the opening height, determines the power of the support bar motor according to the rotation speed of the support bar motor, and calculates the ratio of the work to be done by the support bar motor to the power, so that the ratio of the work to be done by the support bar motor to the power is used as the rotation duration of the support bar motor.
The rotating speed of the supporting rod motor can be set and changed according to the needs of a user, and the embodiment of the invention is not particularly limited to this. For example, the rotation speed of the support rod motor may be 500 r/s.
Step 2052: the PLGM sends the rotation duration to the strut bar motor.
In this step, the PLGM sends the rotation duration to the support bar motor via a wire harness.
Step 2053: the supporting rod motor controls the electric rear tail gate to ascend to the opening height according to the rotating time, the rotating direction and the rotating speed.
In the embodiment of the invention, the PLGM controls the voltage at two ends of the support rod motor through the wire harness, and controls the rotation direction of the support rod motor, so that the support rod motor is driven to control the opening or closing of the electric back door.
In the step, the support rod motor receives the rotation time length sent by the PLGM through the wire harness, determines the rotation direction through the voltages at two ends of the support rod motor, and enters a working state according to the rotation time length, the rotation direction and the rotation speed, so that the electric back door is controlled to rise to the opening height.
As shown in FIG. 1, the PLGM is connected with the support rod motor through a wire harness, and the PLGM controls the voltage V of the A end of the support rod motorAAnd voltage V at terminal BBAnd the support rod motor is controlled to rotate forwards or backwards, so that the support rod motor is driven to control the electric back door to be opened or closed.
The rotation direction of the support rod motor can be set and changed according to the needs of a user, and the embodiment of the invention is not particularly limited to this. For example, the electric back door can be opened when the support rod motor rotates forwards, namely the electric back door rises, and the electric back door is closed when the support rod motor rotates backwards, namely the electric back door falls; the electric back door can be closed when the supporting rod motor rotates forwards, and the electric back door can be opened when the supporting rod motor rotates backwards.
It should be noted that the number of the supporting rod motors may be set and changed according to the needs of the user, and there may be one or more supporting rod motors. For example, the number of the support bar motors may be 2.
In the embodiment of the invention, the vehicle-mounted terminal is also provided with a closing button for closing the electric back door, when the vehicle-mounted terminal detects that the closing button is triggered, the vehicle-mounted terminal generates a closing instruction, the vehicle-mounted terminal sends the closing instruction to the PLGM through the CAN bus, the PLGM receives the closing instruction sent by the vehicle-mounted terminal through the CAN bus, and the voltage at two ends of the supporting rod motor is controlled through the wiring harness according to the closing instruction, so that the rotating direction of the supporting rod motor is controlled, and the supporting rod motor is driven to control the electric back door to be closed.
