[0046] Vehicle 1, driver's side door 2, driver's side door controller 3, built-in battery 4, external power connection interface 5, first power supply terminal 31, second power supply terminal 32, external power supply 6, switch 7, domain controller 8, key management module 9, third power supply terminal 91, fourth power supply terminal 92. Detailed implementation manners

[0047] This application provides a control method for a vehicle, a driver's side door controller, and a computer-readable storage medium. The following will describe in detail the control method for the vehicle, the driver's side door controller, and the computer-readable storage medium of this application with reference to the accompanying drawings. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0048] Please refer to Figure 1 , Figure 1 which is a structural block diagram of the vehicle 1 shown in an embodiment of this application. As Figure 1 shown, the vehicle 1 provided in the embodiment of this application includes a driver's side door controller 3, a driver's side door 2, a built-in battery 4, and an external power connection interface 5. The driver's side door controller 3 is connected to the driver's side door 2 and is used to control the opening of the driver's side door 2.

[0049] In this embodiment, the vehicle 1 includes a built-in battery 4. The driver's side door controller 3 includes a first power supply terminal 31 and a second power supply terminal 32. The first power supply terminal 31 is connected to the built-in battery 4. When the vehicle 1 is not power-depleted, the built-in battery 4 can provide the electric energy required for the operation of the driver's side door controller 3. When the vehicle 1 is power-depleted, the electric energy in the built-in battery 4 is not sufficient to provide the electric energy required for the operation of the driver's side door controller 3.

[0050] The second power supply terminal 32 is connected to the external power connection interface 5. The external power connection interface 5 is used to connect to an external power supply 6. The external power connection interface 5 is disposed outside the vehicle 1. In some implementation manners, the external power connection interface 5 includes a positive terminal and a negative terminal, which are disposed at the rear of the vehicle 1. The external power supply 6 can be a storage battery. When the positive electrode of the storage battery is connected to the positive terminal and the negative electrode of the storage battery is connected to the negative terminal, the driver's side door controller 3 is connected to the external power supply 6 through the external power connection interface 5, and the external power supply 6 provides electric energy for the driver's side door controller 3.

[0051] In this embodiment, the external power connection interface 5 is different from the charging interface of the vehicle 1, and the external power supply 6 is different from the charging pile for charging the vehicle 1. The voltage level of the external power connection interface 5 and the external power supply 6 is lower than the voltage level that can be provided by the charging interface of the vehicle 1 and the charging pile, and the external power connection interface 5 is directly connected to the driver's side door controller 3 and is not connected to the power system of the vehicle 1.

[0052] Please refer to Figure 2 ,Figure 2 Schematic flow diagram of vehicle control method 20 shown in an embodiment of this application. Figure 2 The shown vehicle control method 20 is applied to Figure 1 the main driver's door controller 3 of the shown vehicle 1.

[0053] The vehicle control method 20 includes step 21 and step 22.

[0054] Step 21, obtain the voltage of the first power supply terminal 31 and the voltage of the second power supply terminal 32.

[0055] The first power supply terminal 31 is connected to the built-in battery 4. The voltage of the first power supply terminal 31 can reflect the power condition of the built-in battery 4. When the voltage of the first power supply terminal 31 is the normal operating voltage of the main driver's door controller 3, it indicates that the vehicle 1 is not power-starved. When the voltage of the first power supply terminal 31 is lower than the first voltage limit, it indicates that the vehicle 1 is power-starved, where the first voltage limit is less than the normal operating voltage of the main driver's door controller 3.

[0056] The second power supply terminal 32 is connected to the external power connection interface 5. The external power connection interface 5 is used to connect to an external power source 6. The voltage of the second power supply terminal 32 can reflect whether the external power connection interface 5 is connected to an external power source 6 and provides electrical energy for the main driver's door controller 3. When the external power connection interface 5 is not connected to an external power source 6, the voltage of the second power supply terminal 32 is zero. When the external power connection interface 5 is connected to an external power source 6, the second power supply terminal 32 has voltage.

[0057] Step 22, if the voltage of the first power supply terminal 31 is lower than the first voltage limit and the voltage of the second power supply terminal 32 is greater than the second voltage limit, and the vehicle 1 is in the transportation mode, then control the main driver's door 2 to open; where the first voltage limit is less than the normal operating voltage of the main driver's door controller 3, and the second voltage limit is not less than the normal operating voltage of the main driver's door controller. In this way, when the vehicle 1 is in the transportation mode and power-starved, the main driver's door controller 3 can control the main driver's door 2 to open when it obtains that the external power connection interface 5 is connected to an external power source 6, avoiding the problem that the door cannot be opened when the vehicle 1 in the transportation mode is power-starved.

[0058] Among them, the working modes of the vehicle 1 include the transportation mode and the non-transportation mode. During long-distance transportation of the vehicle 1, the vehicle 1 is generally set to the transportation mode to disable some functions of the vehicle 1, such as entertainment systems, seat adjustments, remote door opening, locking and other functions, which is convenient for saving electrical energy, reducing interference during vehicle 1 transportation, and improving the safety performance of vehicle 1 transportation.

[0059] After the vehicle 1 is sold to the user, the staff will switch the transportation mode to a non - transportation mode. When the vehicle 1 is in the transportation mode, the locking function of the vehicle 1 is disabled and the vehicle 1 is in an unlocked mode. When it is necessary to open the driver's door 2, there is no need to unlock it. When the vehicle 1 is in the non - transportation mode, the vehicle 1 has a locking function. If the vehicle 1 is in the locked state, when it is necessary to open the driver's door 2, unlocking and opening the door are required.

[0060] Please refer to Figure 3 , Figure 3 which is a schematic flow chart of the vehicle control method 20 shown in another embodiment of the present application. In Figure 3 the embodiment shown, the driver's door 2 is provided with a hidden door handle. Most of the time, the hidden handle is smoothly integrated with the vehicle body, reducing the protruding parts, and having functions such as enhancing the appearance of the vehicle 1, reducing air resistance, and preventing the handle from being scratched.

[0061] The vehicle control method 20 further includes step 23.

[0062] Step 23, if the voltage of the first power supply terminal 31 is lower than the first voltage limit value, the voltage of the second power supply terminal 32 is greater than the second voltage limit value, and the vehicle 1 is in the transportation mode, control the hidden door handle to pop out; wherein, the first voltage limit value is less than the normal operating voltage of the driver's door controller 3, and the second voltage limit value is not less than the normal operating voltage of the driver's door controller 3. In this way, while controlling the door to open, the hidden door handle on the driver's door 2 can be controlled to pop out, providing a force - applying point for operating the door when the staff needs to enter the vehicle 1, which is convenient for the staff to enter the vehicle 1 better.

[0063] In some embodiments, controlling the opening of the driver's door includes: obtaining information on whether there is an obstacle within a first preset angle in the opening direction of the driver's door;

[0064] If the information indicates that there is an obstacle, control the driver's door to open at a second preset angle, and the second preset angle is less than the first preset angle;

[0065] If the information indicates that there is no obstacle, control the driver's door to open at the first preset angle.

[0066] Specifically, please refer to Figure 4 , Figure 4 which is a schematic flow chart of the vehicle control method 20 shown in yet another embodiment of the present application. As Figure 4 shown, the vehicle control method 20 further includes step 24.

[0067] Step 24: Obtain information on whether there is an obstacle within a first preset angle in the opening direction of the driver's door 2. This step can be carried out after step 22 when the voltage of the first power supply terminal 31 is lower than the first voltage limit value, the voltage of the second power supply terminal 32 is greater than the second voltage limit value, and the vehicle 1 is in the transportation mode.

[0068] After step 22, when the voltage of the first power supply terminal 31 is lower than the first voltage limit value, the voltage of the second power supply terminal 32 is greater than the second voltage limit value, and the vehicle 1 is in the transportation mode, the driver's door controller 3 needs to control the door to open. Before controlling the door to open, obtaining information on whether there is an obstacle within a first preset angle in the opening direction of the driver's door 2 can determine the safety of the vehicle 1 when opening the door.

[0069] In step 24 of obtaining information on whether there is an obstacle within a first preset angle in the opening direction of the driver's door 2, this information can be obtained by a sensor integrated on the driver's door controller 3 or by other sensors on the vehicle 1 and transmitted to the driver's door controller 3. If this information is obtained by other sensors on the vehicle 1, this sensor is also connected to the external power supply interface 5 outside the vehicle. When the external power supply interface 5 is connected to the external power supply 6, the external power supply 6 will also supply power to this sensor.

[0070] In step 22, controlling the driver's door 2 to open includes step 221 and step 222.

[0071] Step 221: If the information indicates that there is an obstacle, control the driver's door 2 to open to a second preset angle. The second preset angle is smaller than the first preset angle, and the first preset angle is the angle for the vehicle to open the door normally. If the information indicates that there is an obstacle, for the safety during the door opening process, the door is not opened at a large angle, which can avoid touching the obstacle during the door opening process. The staff can manually open the door based on the door opening to the second preset angle, or when the door opens to the second preset angle, reach into the vehicle 1 to operate the vehicle 1.

[0072] Step 222: If the information indicates that there is no obstacle, control the driver's door 2 to open to the first preset angle. The staff can directly enter the cab without further operating the door, improving the convenience for the staff to enter the vehicle and the safety of the vehicle 1 when opening the door.

[0073] Please refer to Figure 5 , Figure 5 For Figure 2 the flowchart of an implementation manner of step 21 in the vehicle control method 20 shown. In Figure 5 the embodiment shown, step 21 of obtaining the voltage of the first power supply terminal 31 and the voltage of the second power supply terminal 32 includes step 211 and step 212.

[0074] Step 211, obtain the voltage of the second power supply terminal 32;

[0075] Step 212, if the voltage of the second power supply terminal 32 is greater than the second voltage limit, obtain the voltage of the first power supply terminal 31.

[0076] Since the power feeding of the vehicle 1 may last for a certain period of time, but for external power connection to open the door, external power connection is only carried out when there is a need to open the door. Therefore, the duration of external power connection is generally shorter than the power feeding duration of the vehicle 1. By first obtaining the voltage of the second power supply terminal 32, if the voltage of the second power supply terminal 32 is greater than the second voltage limit, it indicates that external power connection has been carried out. Then, obtaining the voltage of the first power supply terminal 31 can avoid the waste of computing power caused by the main driver's door controller 3 constantly obtaining the voltage of the first power supply terminal 31.

[0077] In this embodiment, the vehicle control method 20 further includes that if the voltage of the first power supply terminal 31 is lower than the first voltage limit, the voltage of the second power supply terminal 32 is greater than the second voltage limit and less than the third voltage limit, and the vehicle 1 is in the transportation mode, control the main driver's door 2 to open. In this way, when the voltage of the second power supply terminal 32 is between the second voltage limit and the third voltage limit, that is, when the electric energy of the external power supply 6 is qualified, and the voltage of the first power supply terminal 31 is lower than the first voltage limit and the vehicle 1 is in the transportation mode, control the main driver's door 2 to open. In this way, it can avoid the excessive voltage of the external power supply 6 from damaging the main driver's door controller 3.

[0078] Please refer to Figure 6 , Figure 6 For the structural block diagram of the vehicle 1 shown in another embodiment of the present application. In Figure 6 In the shown embodiment, the vehicle 1 includes a switch 7 and a domain controller 8. The switch 7 is arranged outside the vehicle 1. The switch 7 is connected to the domain controller 8, and the domain controller 8 is connected to the main driver's door controller 3. In some implementation manners, the switch 7 is a button and is arranged outside the main driver's door 2, which is convenient for the staff to operate the switch 7. The domain controller 8 is connected to the switch 7 and can sense the state of the switch 7, such as whether the switch 7 is triggered or not. The domain controller 8 is connected to the main driver's door controller 3, and the domain controller 8 can communicate with the main driver's door controller 3.

[0079] In Figure 6 On the basis of the vehicle 1 shown, please refer to Figure 7 , Figure 7 For the flow schematic diagram of the vehicle control method 20 shown in another embodiment of the present application. In Figure 7 In the shown embodiment, the vehicle control method 20 includes Step 21 and Step 25.

[0080] Step 21, obtain the voltage of the first power supply terminal and the voltage of the second power supply terminal;

[0081] Step 25, if the voltage of the first power supply terminal 31 is the normal operating voltage of the driver's door controller 3 and the vehicle 1 is in the transportation mode, in response to the first door opening instruction sent by the domain controller 8 when the switch 7 is triggered, control the driver's door 2 to open. In this way, when the vehicle 1 is in the transportation mode, the door can be opened by operating the switch 7 without the vehicle 1 being powered off.

[0082] Please refer to Figure 8 , Figure 8 which is the structural block diagram of the vehicle 1 shown in another embodiment of the present application. In Figure 8 the embodiment shown, the vehicle 1 further includes a key management module 9. The key management module 9 is connected to the driver's door controller 3. The key management module 9 includes a third power supply terminal 91 and a fourth power supply terminal 92. The third power supply terminal 91 is connected to the built-in battery 4, and the fourth power supply terminal 92 is connected to the external power connection interface 5.

[0083] The third power supply terminal 91 is connected to the built-in battery 4. The voltage of the third power supply terminal 91 can reflect the power situation of the built-in battery 4. When the voltage of the third power supply terminal 91 is the normal operating voltage of the key management module 9, it indicates that the vehicle 1 is not powered off. When the voltage of the third power supply terminal 91 is lower than the fourth voltage limit value, it indicates that the vehicle 1 is powered off, where the fourth voltage limit value is less than the normal operating voltage of the key management module 9.

[0084] The fourth power supply terminal 92 is connected to the external power connection interface 5. The external power connection interface 5 is used to connect an external power supply 6. The voltage of the fourth power supply terminal 92 can reflect whether the external power connection interface 5 is connected to an external power supply 6 to provide power for the key management module 9. When the external power connection interface 5 is not connected to an external power supply 6, the voltage of the fourth power supply terminal 92 is zero. When the external power connection interface 5 is connected to an external power supply 6, the fourth power supply terminal 92 has a voltage.

[0085] In Figure 8 the basis of the vehicle 1 shown, please refer to Figure 9 , Figure 9 which is the flow schematic diagram of the vehicle control method 20 shown in another embodiment of the present application. In Figure 9 the embodiment shown, the vehicle control method 20 includes Step 26 and Step 27.

[0086] Step 26, obtain the voltage of the third power supply terminal 91 and the voltage of the fourth power supply terminal 92. Since both the third power supply terminal 91 and the first power supply terminal 31 are connected to the built-in battery 4, the voltage of the third power supply terminal 91 can be directly obtained, or the voltage of the first power supply terminal 31 can be obtained as the voltage of the first power supply terminal 31. Both the second power supply terminal 32 and the fourth power supply terminal 92 are connected to the external power connection interface 5. The voltage of the fourth power supply terminal 92 can be directly obtained, or the voltage of the second power supply terminal 32 can be obtained as the voltage of the fourth power supply terminal 92.

[0087] Step 27, if the voltage of the first power supply terminal 31 is lower than the first voltage limit value, the voltage of the second power supply terminal 32 is greater than the second voltage limit value, the voltage of the third power supply terminal 91 is lower than the fourth voltage limit value, the voltage of the fourth power supply terminal 92 is greater than the fifth voltage limit value, and the vehicle 1 is in a non-transport mode, in response to the first unlocking instruction generated when the first unlocking request authentication of the wireless authentication device by the key management module 9 is passed, control the main driver's door 2 to unlock and open.

[0088] The voltage of the first power supply terminal 31 is lower than the first voltage limit value, the voltage of the second power supply terminal 32 is greater than the second voltage limit value, the voltage of the third power supply terminal 91 is lower than the fourth voltage limit value, and the voltage of the fourth power supply terminal 92 is greater than the fifth voltage limit value, indicating that the vehicle 1 is power-fed and has been jump-started through the external jump-start interface 5. If the vehicle 1 is in a non-transport mode and in a locked state at this time, when the main driver's door 2 needs to be opened, the unlocking step and the door-opening step are required.

[0089] The main driver's door controller 3 controls the main driver's door 2 to unlock and open in response to the first unlocking instruction generated when the first unlocking request authentication of the wireless authentication device by the key management module 9 is passed.

[0090] The wireless authentication device can be a FOB (remote control key of the vehicle 1), mobile phone Bluetooth, NFC, etc. The user operates the wireless authentication device to send a first unlocking request authentication to the key management module 9. If the wireless authentication device and the key management module 9 match, the key management module 9 will pass the first unlocking request authentication of the wireless authentication device and generate a first unlocking instruction to the main driver's door controller 3, and the main driver's door controller 3 controls the door to unlock and open.

[0091] Please refer to Figure 10 , Figure 10 which is the structural block diagram of the vehicle 1 shown in another embodiment of the present application; in Figure 10 the embodiment shown, the vehicle 1 includes a switch 7 and a domain controller 8. The switch 7 is provided outside the vehicle 1. The switch 7 is connected to the domain controller 8, and the domain controller 8 is connected to the main driver's door controller 3. The vehicle 1 further includes a key management module 9. The key management module 9 is connected to the domain control. The key management module 9 includes a third power supply terminal 91, and the third power supply terminal 91 is connected to the built-in battery 4.

[0092] In Figure 10 on the basis of the vehicle 1 shown, please refer to Figure 11 , Figure 11 which is the flow schematic diagram of the vehicle control method 20 shown in another embodiment of the present application. In Figure 11 the embodiment shown, the vehicle control method 20 includes Step 28, Step 29 and Step 30.

[0093] Step 28, obtain the voltage of the third power supply terminal 91;

[0094] Step 29, if the voltage of the first power supply terminal 31 is the normal operating voltage of the driver's door controller 3, the voltage of the third power supply terminal 91 is the normal operating voltage of the key management module 9, and the vehicle 1 is in the non-transport mode, in response to the second unlocking instruction generated when the second unlocking request authentication of the key management module 9 is passed by the wireless authentication device, control the driver's door 2 to unlock.

[0095] Step 30, in response to the second door opening instruction sent by the domain controller 8 when the switch 7 is triggered, control the driver's door 2 to open.

[0096] The voltage of the first power supply terminal 31 is the normal operating voltage of the driver's door controller 3, and the voltage of the third power supply terminal 91 is the normal operating voltage of the key management module 9, indicating that the vehicle 1 is not power-fed. When the vehicle 1 is not power-fed and the vehicle 1 is in the non-transport mode and in the locked state, the user operates the wireless authentication device to send a second unlocking request authentication to the key management module 9. If the wireless authentication device and the key management module 9 match, the key management module 9 will pass the second unlocking request authentication of the wireless authentication device and generate a second unlocking instruction to the driver's door controller 3, and the driver's door controller 3 controls the driver's door 2 to unlock. It can be understood that the user operating the wireless authentication device can also unlock other doors. When unlocking the door, if the handle on the door is a hidden handle, the unlocking of the door and the ejection of the hidden handle can also be synchronized.

[0097] After the user unlocks the driver's door 2 by operating the wireless authentication device, the driver's door 2 is opened through Step 30. The user operates the switch 7. When the domain control senses that the switch 7 is triggered, it sends a second door opening instruction to the driver's door controller 3, and the driver's door controller 3 controls the driver's door 2 to open.

[0098] Another aspect of the present application provides a driver's door controller 3, Figure 12 which is a structural block diagram of the driver's door controller 3 shown in an embodiment.

[0099] On the other hand, the present application provides a computer-readable storage medium having a program stored thereon, and when the program is executed, a control method for the vehicle 1 is implemented. In some embodiments, it may be in the form of a computer program product implemented on one or more computer-readable storage media 42 (including but not limited to disk storage, CD-ROM, optical storage, etc.) that contain program code.
