Description

Technical Field

[0001] The present invention relates to the technical field of vehicle control, and particularly to a control method, device, equipment and storage medium for an automotive electric door lock. Background Art

[0002] With the development of the automotive industry, the intelligentization, electrification and convenience of vehicles have become the mainstream of development. The forms of unlocking / locking request signals for vehicle doors have become increasingly diverse. At the same time, from the initial manual pulling to the recent driving methods through electric hinges or electric struts to achieve electric opening and closing of vehicle doors, the opening and closing actions of vehicle doors have become increasingly convenient. For electrically opened / closed vehicle doors, the coordination between the unlocking / locking of the door lock and the electric drive for opening / closing the door is very crucial.

[0003] In the related art, when the door lock is unlocked, the door will cause the lock tongue to disengage from the lock catch under the action of the sealing reaction force. When the lock tongue is completely disengaged from the lock catch, that is, when the door lock is unlocked to the fully open state, the electric drive for opening the door will execute the door opening action.

[0004] However, when the vehicle body is tilted, the component force of the vehicle door weight in the direction of opening and closing the door will increase sharply. When the vehicle body tilt angle reaches a certain angle, the unlocking action of the door lock will not be able to make the door lock reach the fully open state. At this time, the electric drive for opening the door cannot execute the door opening action. Without the manual pushing action of the door, the door lock will quickly enter the semi-closed or fully closed state, and the occupant needs to execute the unlocking and opening actions again, which brings inconvenience to the occupant. If the sealing reaction force is further increased, the closing force will be increased, which will increase the difficulty for the electric drive for closing the door and also increase the cost.

[0051] Hereinafter, the exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

[0052] Various schematic diagrams according to the embodiments of the present disclosure are shown in the drawings. These figures are not drawn to scale, where for the purpose of clear expression, some details are enlarged and some details may be omitted.

[0053] In the context of the present disclosure, when a layer / element is referred to as being "on" another layer / element, the layer / element can be directly on the other layer / element, or there can be an intermediate layer / element between them. Additionally, if a layer / element is "on" another layer / element in one orientation, then when the orientation is reversed, the layer / element can be "under" the other layer / element. In the context of the present disclosure, similar or identical components may be denoted by the same or similar reference numerals.

[0054] To better understand the above technical solutions, the above technical solutions will be described in detail below in combination with specific implementation manners. It should be understood that the embodiments of the present disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0055] Vehicle manufacturers consider the situation during normal flat-road parking during the design process, ensuring that when the door is unlocked, the lock tongue of the door lock can disengage from the lock catch under the action of the sealing reaction force, so that the door lock is in the fully open state (i.e., the unlocked state) before the door-opening electric drive device operates. However, when the vehicle body is tilted and parked, the component force of the door weight in the door-opening and closing directions will increase sharply. For example, when the vehicle door is tilted by 10°, with a conventional door weight of 30 kg and the center of gravity of the door 500 mm away from the hinge axis, the load torque will increase by 30 * 9.8 * 0.5 * sin(10) = 25.5 Nm. The sealing reaction force provided by the sealing strip is 25 - 30 Nm under normal conditions. At this time, the vehicle door may not be able to be opened under the action of the sealing reaction force. The lock tongue and the lock catch cannot be completely disengaged to reach the fully open state. Without manual door-pushing action, the door lock will quickly enter the semi-closed or fully-closed state. And if the sealing reaction force is further increased, the cost will increase.

[0056] To solve the above technical problems, an embodiment of the present invention provides a control method for an automotive electric door lock: during the unlocking and door-opening process, a determination process of the vehicle body inclination angle is added. According to different determination results of the vehicle body inclination angle, two different control logics are adopted to realize the coordination of the door-opening unlocking action and the door-opening electric drive action, so that the vehicle door can be successfully opened whether the vehicle is parked on a horizontal road surface or a sloped road surface. Without increasing the cost, the portability of the customer using the electric door-opening function is improved.

[0057] Figure 1 is a flowchart of a control method for an automotive electric door lock provided by an embodiment of the present invention. As Figure 1 shown, this control method is used for the in-vehicle controller to control the door unlocking, and this control method includes:

[0058] Step S101, when receiving the unlocking and door-opening signal, obtain the relevant parameters for unlocking and door-opening.

[0059] Among them, the unlocking and door-opening signal may include a remote unlocking and door-opening signal from a mobile phone app, a remote control key unlocking button signal, a door external unlocking switch signal, a door internal unlocking switch signal, a central control virtual unlocking signal, etc.

[0060] In this embodiment, the relevant parameters for unlocking and door-opening may include a vehicle speed parameter and an external obstacle distance parameter. It should be noted that in other embodiments of the present invention, in addition to the above two parameters, the relevant parameters for unlocking and door-opening may also include other parameters related to door-opening, and the present invention does not limit this.

[0061] Step S102, according to the relevant parameters for unlocking and door-opening, determine whether the preset door-opening condition is satisfied.

[0062] Optionally, when the vehicle speed parameter is less than the set vehicle speed threshold and the off-vehicle obstacle distance parameter indicates that there is no obstacle in the door opening area, it is determined that the preset door opening condition is satisfied.

[0063] Exemplarily, the set vehicle speed threshold can be 5 km / h.

[0064] In this embodiment, when one of the vehicle speed parameter is greater than the set threshold or the off-vehicle obstacle distance parameter indicates that there is an obstacle in the door opening area is established, it is determined that the preset door opening condition is not satisfied. When it is determined that the preset door opening condition is not satisfied, the door opening action is stopped and an alarm is given.

[0065] Step S103: When it is determined that the preset door opening condition is satisfied, determine the current vehicle body inclination angle.

[0066] Among them, the vehicle body inclination angle includes the left-right inclination angle and the front-rear pitch angle of the vehicle body. In this embodiment, it can be detected by a sensor.

[0067] Figure 2 and Figure 3 are schematic diagrams of two types of inclined parking of vehicles provided by the embodiments of the present invention. As Figure 2 shown, if the road surface where the vehicle is parked is uneven or has a slope, the vehicle body will generate a left-right inclination angle α. As Figure 3 shown, the vehicle body will generate a front-rear pitch angle β, and the gravity of the door will also generate a component force in the direction of opening and closing the door.

[0068] Optionally, after executing step S103 and before executing step S104, the control method may further include: determining whether the current vehicle body inclination angle meets the preset inclination angle condition. Specifically:

[0069] The first step: Set the left-right inclination angle threshold and the front-rear pitch angle threshold of the vehicle body.

[0070] In this embodiment, the threshold of the left-right inclination angle of the vehicle body can be set to 15°, and the threshold of the front-rear pitch angle of the vehicle body can be set to 30°.

[0071] The second step: Establish an inclination angle condition judgment matrix according to the left-right inclination angle threshold and the front-rear pitch angle threshold of the vehicle body.

[0072] Among them, the inclination angle condition judgment matrix is used to indicate whether the corresponding vehicle body inclination angle meets the preset inclination angle condition under different left-right inclination angles and different front-rear pitch angles. As shown in Table 1 below:

[0073] Table 1

[0074]

[0075]

[0076] In this embodiment, the resolution of the vehicle body inclination sensor is 0.2°. To simplify the step size and thus reduce the computational load of the controller, the step size of the left and right tilt angles α can be set to 3°, and the step size of the front and rear pitch angles β can be set to 6°.

[0077] Among them, the first row in the inclination angle condition judgment matrix is the left and right tilt angles α of different magnitudes. For example, [0, 3) corresponds to 0° ≤ α < 3°, and [3, 6) corresponds to 3° ≤ α < 6°. The first column in the inclination angle condition judgment matrix is the front and rear pitch angles β of different magnitudes. For example, [0, 6) corresponds to 0° ≤ β < 6°, and [6, 12) corresponds to 6° ≤ β < 12°. 0 in the inclination angle condition judgment matrix indicates that the vehicle body inclination angle does not meet the preset inclination angle condition; 1 indicates that the vehicle body inclination angle meets the preset inclination angle condition.

[0078] The third step: According to the pre-established inclination angle condition judgment matrix, determine whether the current vehicle body inclination angle meets the preset inclination angle condition.

[0079] Exemplarily, when the collected left and right tilt angles of the vehicle body are 5° and the front and rear pitch angles are 10°, the corresponding inclination angle condition in the condition judgment matrix is 0, indicating that the inclination angle of the vehicle body does not meet the preset inclination angle condition at this time. When the collected left and right tilt angles of the vehicle body are 10° and the front and rear pitch angles are 20°, the corresponding inclination angle condition in the condition judgment matrix is 1, indicating that the inclination angle of the vehicle body meets the preset inclination angle condition at this time.

[0080] Step S104: When the vehicle body inclination angle does not meet the preset inclination angle condition, control the execution of the electric unlocking action of the door lock, and according to the door lock status signal, execute the electric drive action of opening the door according to the first control logic.

[0081] In this embodiment, the door lock status signal is used to indicate that the door lock is in the fully open state, the half-closed state or the fully closed state. Among them, when the door lock is in three different states, it represents that the door lock tongue and the lock catch are in three different relative positions.

[0082] Figure 4 It is a schematic diagram of the door lock in the fully open state provided by an embodiment of the present invention. As Figure 4 shown, at this time, the door lock is in the fully open state, and the door lock tongue 1 and the lock catch 2 are completely separated. Figure 5 It is a schematic diagram of the door lock in the half-closed state provided by an embodiment of the present invention. As Figure 5 shown, at this time, the door lock is in the half-closed state, the lock catch 2 has initially entered the lock groove of the lock tongue 1, and the upper part 1a of the lock tongue 1 abuts against the pawl 3. Figure 6 It is a schematic diagram of the door lock in the fully closed state provided by an embodiment of the present invention. As Figure 6 shown, at this time, the door lock is in the fully closed state, the lock catch 2 has completely entered the lock groove of the lock tongue 1, and the lower part 1b of the lock tongue 1 abuts against the pawl 3.

[0083] In this embodiment, performing the door-opening electric drive action according to the door lock state signal in step S104 includes:

[0084] When the door lock state signal indicates that the door lock is in the fully open state, perform the door-opening electric drive action.

[0085] Specifically, when the vehicle body inclination angle does not meet the preset inclination angle condition, perform the electric unlocking action of the door lock. At this time, the door lock will release the motor-driven unlocking, and the relative position of the lock tongue and the lock buckle will change from the fully closed state to the fully open state. The door will open under the action of the sealing reaction force and drive the door lock to disengage from the lock buckle synchronously. At this time, execute the first control logic: that is, when it is detected that the door lock state signal indicates that the door lock is in the fully open state, the controller then controls the door-opening electric drive device to perform the door-opening action and drive the door to open completely.

[0086] It should be noted that when the door lock state has not reached the fully open state, the door-opening electric drive does not perform the door-opening action.

[0087] Step S105, when the vehicle body inclination angle meets the preset inclination angle condition, control the execution of the electric unlocking action of the door lock, and perform the door-opening electric drive action according to the door lock state signal according to the second control logic.

[0088] Optionally, performing the door-opening electric drive action according to the door lock state signal in step S105 includes:

[0089] When the door lock state signal indicates that the door lock state changes from the fully closed state to other states, perform the door-opening electric drive action. It can also be understood that the door lock signal is divided into a first door lock signal, a second door lock signal, and a third door lock signal. Among them, the first door lock signal is used to indicate that the door lock is in the fully closed state, the second door lock signal is used to indicate that the door lock is in the fully closed state, and the third door lock signal is used to indicate that the door lock is in the half-closed state. When it is detected that the first door lock signal generates a jump, that is, perform the door-opening electric drive action.

[0090] Specifically, when the vehicle body inclination angle meets the preset inclination angle condition, perform the electric unlocking action of the door lock. At this time, the door lock will release the motor-driven unlocking, and the relative position of the lock tongue and the lock buckle will change from the fully closed state to the fully open state. Due to the excessive vehicle body inclination angle, the door may not be able to open under the action of the sealing reaction force. At this time, execute the second control logic: that is, when the door lock state signal indicates that the door lock changes from the fully closed state to other states, the controller then controls the door-opening electric drive device to perform the door-opening electric drive action and drive the door to open completely.

[0091] Optionally, the control method further includes:

[0092] During the execution of the door-opening electric drive operation, if the preset door-opening condition changes from being satisfied to not being satisfied, the execution of the door-opening electric drive operation is stopped and an alarm is issued.

[0093] It can be understood that during the execution of the door-opening electric drive, the relevant parameters for unlocking and opening the door will be obtained again in real time. If it is determined based on the relevant parameters for unlocking and opening the door obtained again that the current preset door-opening condition is not satisfied, it is necessary to immediately stop the execution of the door-opening electric drive operation and issue an alarm.

[0094] Figure 7 It is a flowchart of another control method for an automotive electric door lock provided by an embodiment of the present invention. As Figure 7 shown, this part of the control method is used for the in-vehicle controller to control the door locking. This control method includes:

[0095] Step S701: When a locking and closing door signal is received, execute the door-closing electric drive operation.

[0096] Among them, the locking and closing door signal can be any one of a mobile phone app remote locking and closing door signal, a remote control key locking button signal, a door external locking switch signal, a door internal locking switch signal, or a central control virtual locking signal.

[0097] Step S702: When the door lock status signal indicates that the door lock is in the half-closed state, stop executing the door-closing electric drive operation and execute the door lock electric suction operation.

[0098] Step S703: When the door lock status signal indicates that the door lock is in the fully-closed state, stop executing the door lock electric suction operation.

[0099] Among them, when the door lock status signal indicates that the door lock is in the fully-closed state, it means that the door has been closed, and the door lock electric suction operation is stopped.

[0100] Based on the same inventive concept, an embodiment of the present invention provides a device corresponding to the control method described in the embodiments of the present application. Figure 8 It is a schematic structural diagram of a control device for an automotive electric door lock provided by an embodiment of the present invention.

[0125] The technical solutions in the embodiments of the present application above have at least the following technical effects or advantages:

[0126] A control method, device, equipment and storage medium for an automotive electric door lock provided by an embodiment of the present invention, when receiving an unlock and open door signal, determines whether the vehicle meets a preset door opening condition by obtaining relevant parameters for unlocking and opening the door. When the preset door opening condition is met, the current body inclination angle is determined, including the left-right inclination angle and the front-back pitching angle of the body, to judge the inclination state of the body. When the body inclination angle does not meet the preset inclination angle condition, the control executes the electric unlocking action of the door lock. At this time, the door lock will move from fully closed to fully open, and then according to the status signal of the door lock, the opening electric drive action is executed according to the first control logic. When the body inclination angle meets the preset inclination angle condition, the control executes the electric unlocking action of the door lock. At this time, the door lock will move from fully closed to fully open, and then according to the status signal of the door lock, the opening electric drive action is executed according to the second control logic. The above control method adopts two different control logics to control the opening electric drive to act, so that whether the vehicle is parked on a horizontal road surface or a sloped road surface, it can ensure the close cooperation between the door lock unlocking action and the opening electric drive, and successfully open the door. It avoids that during the door opening process, the door lock enters the semi-closed state or the fully locked state again, making the door unable to be opened. Without increasing the cost, the portability of the customer using the electric door opening is improved.
