These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0053] In the field of vehicles, an inner handle is usually provided on a door of a vehicle, and a user of the vehicle opens the door by pulling the inner handle.

[0054] In one example, based on the double-pull opening function of the door lock of a car door, the user needs to pull the inner handle twice in succession to open the door when inside the car.

[0055] However, in the above method, after the user pulls the inner handle due to an error, if the user pulls the inner handle again due to an error, the door will open, and there is a risk of the door opening by mistake, affecting the driving safety of the vehicle and the user.

[0056] In view of the above technical problems, the present application proposes the following technical concept: based on the electronic control unit of the vehicle door module, after the user pulls the inner handle of the door for the first time, the door lock state of the door lock is switched from the fully locked state to the semi-unlocked state. If it is determined that the user does not pull the inner handle again within a preset time period, the door lock is controlled to switch from the semi-unlocked state to the fully locked state. If it is detected that the user pulls the inner handle again to open the door within the preset time period, the door state is determined to be the open state. In this way, the problem of the user's mistaken opening of the door due to misoperation in the prior art can be solved, thereby affecting the driving safety of the vehicle and the user.

[0057] Figure 1 A schematic diagram of an application scenario provided by this application. Figure 1 As shown, the specific application scenario of the present application includes a door lock 101, an inner handle 102, a door module electronic control unit (Door Module Electronic Control Unit, referred to as door module ECU) 103 and a body controller 104 of a vehicle door. Based on the double-pull opening function of the door lock 101 in the door, the door module ECU 103 monitors whether the user pulls the inner handle 102 twice in a preset time continuously, controls the door lock 101 to unlock, and realizes opening the door. The body controller 104 can communicate with the door module ECU 103 through the in-vehicle controller local area network bus (Controller Area Network, referred to as CAN), and can monitor the unlocking status of the door lock 101 and the opening status of the door.

[0058] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0059] Figure 2 A schematic diagram of a door control method provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the method includes:

[0060] 201. If it is determined that the vehicle door is in a closed state and the door lock is in a fully locked state, the state switching information of the door lock is monitored; wherein the state switching information indicates that the door lock state of the door lock is switched from a fully locked state to a semi-unlocked state; the state switching information is generated based on the user pulling the inner handle of the door for the first time.

[0061] Exemplarily, the execution subject of this embodiment may be a door module ECU. The vehicle is provided with a door, a door module ECU, and a body controller. Based on the door module ECU, the open or closed state of the door can be obtained from the body controller through the CAN bus, and the door lock state of the door can be obtained. Based on the double-pull opening principle of the door lock, the door lock state of the door lock is a fully locked state, a semi-unlocked state, or an unlocked state. When the door module ECU determines that the vehicle door is in a closed state and the door lock of the door is in a fully locked state, at this time, the user pulls the inner handle of the door for the first time. Based on the pulling action of the inner handle and the double-pull opening principle between the door locks, the door lock state of the door lock is switched from a fully locked state to a semi-unlocked state, that is, the state switching information of the door lock is generated accordingly.

[0062] After step 201, step 202 or step 203 may be executed.

[0063] 202. If the first unlocking signal of the fully locked position switch in the vehicle door lock is not detected within a preset time period, the door lock state of the vehicle door lock is controlled to switch from a semi-unlocked state to a fully locked state; wherein the first unlocking signal represents that the switch state of the fully locked position switch is switched from a locked state to an unlocked state; and the first unlocking signal is generated based on the user pulling the inner handle again.

[0064] Exemplarily, after step 201, based on the full lock position switch being set in the door lock, after the state switching information of the door lock is monitored, the timing is started, that is, a preset time period is set, based on the principle that the user pulls the inner handle again within the preset time period so that the switch state of the full lock position switch is switched from the locked state to the unlocked state, if the first unlocking signal of the full lock position switch in the door lock is not detected within the preset time period, that is, the user does not pull the inner handle again within the preset time period, resulting in the switch state of the full lock position switch not changing within the preset time period, then based on the door module ECU, the door lock state of the door lock can be controlled to switch from the semi-unlocked state to the fully locked state through the body controller or itself, that is, in this process, the switch state of the full lock position switch is always in the locked state, and then, after the preset time period, when the user pulls the inner handle again, the door will not open.

[0065] 203. If a first unlocking signal is detected within a preset time period, it is determined that the vehicle door is in an open state.

[0066] Exemplarily, after step 201, based on the principle that the user pulls the inner handle again within a preset time period to switch the switch state of the full-lock position switch from a locked state to an unlocked state, if the door module ECU detects the first unlocking signal of the full-lock position switch in the door lock within the preset time period, that is, the user pulls the inner handle again within the preset time period, causing the switch state of the full-lock position switch within the preset time period to switch from a locked state to an unlocked state, at this time, the door lock of the door is in an unlocked state, the door will open, and the door module ECU can determine through the body controller or directly by itself that the door is in an open state.

[0067] In the present embodiment, a vehicle door control method is provided, which is based on the vehicle door module electronic control unit. After the user pulls the inner handle of the vehicle door for the first time, the door lock state of the vehicle door is switched from a fully locked state to a semi-unlocked state. If the user does not pull the inner handle again within a preset time period, the vehicle door lock is controlled to switch from the semi-unlocked state to a fully locked state. If the user is monitored to pull the inner handle again to open the vehicle door within the preset time period, the state of the vehicle door is determined to be an open state; thereby, the vehicle door is prevented from being accidentally opened due to misoperation by the user, so as to ensure the driving safety of the vehicle and the user.

[0068] Figure 3 A flow chart of another door control method provided in an embodiment of the present application is shown as follows: Figure 3 As shown, the method includes:

[0069] 301. If it is determined that the inner handle micro switch is in the locked state and the full-lock position switch of the door lock is in the locked state, then it is determined that the door lock is in the full-lock state; at the same time, it is determined that the door is in the closed state.

[0070] Among them, the vehicle door also includes an inner handle micro switch; the full lock position switch includes a double pull door lock structure.

[0071] For example, Figure 4 A schematic diagram of the principle of a door control function provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the vehicle door also includes an inner handle microswitch, which is connected to the inner handle and the door module ECU respectively, and the inner handle and the vehicle door lock are mechanically connected. When the user pulls the inner handle, the switching state of the inner handle microswitch is switched from a locked state to an unlocked state; the full lock position switch includes a double-pull door lock structure. Based on the double-pull opening and resetting functions, the reset state of the double-pull door lock structure is a double-pull reset state or a non-reset position state. When the user pulls the inner handle, the double-pull door lock structure is in a non-reset position state. At this time, the full lock position switch is still in a locked state, that is, the vehicle door lock is in a semi-unlocked state. When the user pulls the inner handle again, the non-reset position state of the double-pull door lock structure changes. At this time, the full lock position switch is in an unlocked state, that is, the vehicle door lock is in an unlocked state. Based on the door module ECU, the switching state of the inside handle microswitch and the reset state of the double-pull door lock structure of the full-lock position switch in the door lock can be monitored. When it is determined that the inside handle microswitch is in the locked state and the full-lock position switch of the door lock is in the locked state, it is determined that the door lock of the door is in the full-lock state. At the same time, it can be determined that the door is in the closed state.

[0072] 302. If the second unlocking signal of the inner handle micro switch and the reset signal of the double-pull door lock structure in the vehicle door lock are monitored, it is determined that the door lock state of the vehicle door lock is switched from a fully locked state to a semi-unlocked state; wherein the second unlocking signal indicates that the switch state of the inner handle micro switch is switched from a locked state to an unlocked state; the reset signal indicates that the reset state of the double-pull door lock structure is switched from a double-pull reset state to a non-reset position state; the second unlocking signal and the reset signal are both generated based on the user pulling the inner handle of the vehicle door for the first time.

[0073] Exemplarily, after determining that the door lock of the vehicle door is in the fully locked state and at the same time, it can be determined that the door is in the closed state, the door lock state of the door lock can be monitored. If the user pulls the inner handle of the door for the first time, the switch state of the inner handle microswitch is switched from the locked state to the unlocked state, and at the same time, the reset state of the double-pull door lock structure is switched from the double-pull reset state to the non-reset position state, that is, the door module ECU monitors the second unlocking signal of the inner handle microswitch and the reset signal of the double-pull door lock structure in the door lock. At this time, it is determined that the door lock state of the door lock is switched from the fully locked state to the semi-unlocked state.

[0074] After step 302, step 303 or step 304 may be executed.

[0075] 303. If the first unlocking signal of the full-lock position switch in the vehicle door lock is not detected within the preset time period, the switch state of the inner handle microswitch is controlled to switch from the unlocking state to the locking state; at the same time, the reset state of the double-pull door lock structure is controlled to switch from the non-reset position state to the double-pull reset state.

[0076] Exemplarily, after step 302, when the door module ECU determines that the door lock state of the vehicle door lock has switched from the fully locked state to the semi-unlocked state, it starts timing, that is, sets a preset time period, based on the principle that the user pulls the inner handle again, causing the reset state of the double-pull door lock structure in the fully locked position switch to change again from the non-reset position switch state, causing the switch state of the fully locked position switch to switch from the locked state to the unlocked state, if it is determined that the first unlocking signal of the fully locked position switch in the vehicle door lock is not detected within the preset time period, that is, the user does not pull the inner handle again within the preset time period, then it is necessary to control the switch state of the inner handle microswitch to switch from the unlocked state to the locked state; at the same time, the reset state of the double-pull door lock structure is controlled to switch from the non-reset position state to the double-pull reset state, that is, the switch state of the fully locked position switch is still in the locked state, and the vehicle door lock is in the fully locked state. Furthermore, after the preset time period, if the user pulls the inner handle again, the vehicle door cannot be opened.

[0077] 304. If a first unlocking signal is detected within a preset time period, it is determined that the vehicle door is in an open state.

[0078] Exemplarily, when the door module ECU determines that the door lock state of the vehicle door lock has switched from a fully locked state to a semi-unlocked state, it starts timing, that is, sets a preset time period, based on the principle that the user pulls the inner handle again, causing the reset state of the double-pull door lock structure in the fully locked position switch to change again from the non-reset position switch state, causing the switch state of the fully locked position switch to switch from the locked state to the unlocked state. If it is determined that the first unlocking signal of the fully locked position switch in the vehicle door lock is monitored within the preset time period, that is, the user pulls the inner handle again within the preset time period, the reset state of the double-pull door lock structure changes again from the non-reset position state, so that the switch state of the fully locked position switch is the unlocked state. At this time, the vehicle door lock is in the unlocked state, and then the vehicle door is opened, and the door module ECU can determine that the vehicle door is in the open state.

[0079] 305. Control the reset state of the double-pull door lock structure to return to the double-pull reset state.

[0080] For example, after the door module ECU determines that the vehicle door is in the open state, it needs to restore the reset state of the double-pull door lock structure in the double full-lock position switch to the double-pull reset state, maintain the double-pull opening function of the door lock, so that after the vehicle door is closed again, the user needs to pull the inner handle twice in a preset time period to open the door.

[0081] In this embodiment, on the basis of the above embodiment, after monitoring the switch state change of the inner handle micro switch, the reset state change of the double-pull door lock structure of the full lock position switch in the door lock within the preset time period is continued to be monitored to determine whether the user pulls the inner handle twice in a row within the preset time period, thereby reducing the risk of the door being accidentally opened due to the user pulling the inner handle due to misoperation, thereby ensuring the driving safety of the vehicle and the user.

[0082] Figure 5 A flow chart of another door control method provided in an embodiment of the present application is shown as follows: Figure 5 As shown, the method includes:

[0083] 401. If it is determined that the locking micro switch of the vehicle door lock is in the locked state and the full-lock position switch is in the locked state, then it is determined that the vehicle door lock is in the full-lock state; and it is determined that the vehicle door is in the closed state.

[0084] Among them, the door lock also includes a locking micro switch.

[0085] For example, Figure 6 A schematic diagram of another door control function provided by an embodiment of the present application is shown in FIG. Figure 6 As shown, the door lock also includes a locking micro switch, which is connected to the door module ECU, and the inner handle is mechanically connected to the door lock. When the user pulls the inner handle, the switch state of the locking micro switch is switched from the locked state to the unlocked state; at this time, the full lock position switch is still in the locked state, that is, the door lock is in a semi-unlocked state. Based on the door module ECU, the switch state of the locking micro switch and the switch state of the full lock position switch in the door lock can be monitored. When it is determined that the locking micro switch of the door lock is in the locked state and the full lock position switch is in the locked state, it is determined that the door lock of the vehicle door is in the full lock state, and at the same time, it can be determined that the door is in the closed state.

[0086] 402. If a third unlocking signal of the locking micro switch is detected, it is determined that the door lock state of the vehicle door lock is switched from a fully locked state to a semi-unlocked state; wherein the third unlocking signal indicates that the switch state of the locking micro switch is switched from a locked state to an unlocked state; and the third unlocking signal is generated based on the user pulling the inner handle of the vehicle door for the first time.

[0087] Exemplarily, after determining that the door lock of the vehicle door is in the fully locked state and at the same time, it can be determined that the door is in the closed state, the door lock state of the door lock can be monitored. If the user pulls the inner handle of the door for the first time, so that the switch state of the locking microswitch is switched from the locked state to the unlocked state, that is, the door module ECU monitors the third unlocking signal of the locking microswitch, at this time, it is determined that the door lock state of the door lock is switched from the fully locked state to the semi-unlocked state.

[0088] After step 402, step 403 or step 404 may be executed.

[0089] 403. If the first unlocking signal of the full-lock position switch in the door lock is not detected within a preset time period, the switch state of the locking micro switch is controlled to switch from the unlocking state to the locking state.

[0090] Exemplarily, after step 402, when the door module ECU determines that the door lock state of the vehicle door lock has switched from the fully locked state to the semi-unlocked state, the timing starts, that is, a preset time period is set, based on the principle that the user pulls the inner handle again to cause the switch state of the fully locked position switch to switch from the locked state to the unlocked state, if it is determined that the first unlocking signal of the fully locked position switch in the vehicle door lock is not detected within the preset time period, that is, the user has not pulled the inner handle again within the preset time period, then it is necessary to control the switch state of the locking microswitch to switch from the unlocked state to the locked state. At this time, the switch state of the fully locked position switch is still in the locked state, that is, the vehicle door lock is in the fully locked state, and further, after the preset time period, if the user pulls the inner handle again, the vehicle door cannot be opened.

[0091] 404. If a first unlocking signal is detected within a preset time period, it is determined that the vehicle door is in an open state.

[0092] Exemplarily, after step 402, when the door module ECU determines that the door lock state of the vehicle door lock has switched from the fully locked state to the semi-unlocked state, it starts timing, that is, sets a preset time period, based on the principle that the user pulls the inner handle again to cause the switch state of the fully locked position switch to switch from the locked state to the unlocked state, if it is determined that the first unlocking signal of the fully locked position switch in the vehicle door lock is monitored within the preset time period, that is, the user pulls the inner handle again within the preset time period, so that the switch state of the fully locked position switch is the unlocked state, then the vehicle door lock is in the unlocked state, and then the vehicle door is opened, and the door module ECU can determine that the vehicle door is in the open state.

[0093] In this embodiment, based on the above embodiment, after monitoring the switch state change of the locking microswitch, the switch state change of the full lock position switch in the door lock within the preset time period is continued to be monitored to determine whether the user pulls the inner handle twice in a row within the preset time period, thereby reducing the risk of the door being accidentally opened due to the user pulling the inner handle by mistake, thereby ensuring the driving safety of the vehicle and the user.
