[0043] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0044] It should be understood that the present application is directed to a vehicle with power operated doors, the handle of the vehicle is a hidden handle or a semi-hidden handle.

[0045] The whole system, as shown in Figure 1 and Figure 2 includes a power door controller 1, a power door drive mechanism 2, a hidden outer handle 3 and a power operated door lock 4.

[0046] There are two ways to open the door from the outside by the outer handle:

[0047] The first way is that, in general, by pressing the micro switch 301 on the outside of the hidden outer handle 3, at this time the power door controller 1 receives the micro switch 301 electrical signal, the power door controller 1 will drive the power operated door lock 4 to unlock, and power supply to the power door drive mechanism 2, the power door drive mechanism 2 realizes the automatic opening of the door.

[0048] The second way is also to pull the hidden outer handle handle 302, the handle rotating process will trigger a micro switch electrical signal, the micro switch electrical signal to the power door controller 1, the power door controller 1 will drive the power operated door lock 4 to unlock, and power supply to the power door drive mechanism 2, the power door drive mechanism 2 realizes the automatic opening of the door.

[0049] Therefore, the power operated door will generate a micro switch electrical signal by mistake during the collision process, that is, the micro switch electrical signal will be sent in the first way or the second way during the collision process, such as vehicle rollover, vehicle scraping with obstacles on both sides, so that the micro switch 301 is pressed under stress, or the vibration during the collision process causes the micro switch electrical signal, which will cause the door to open and cause secondary injury to the passengers.

[0050] In addition, the collision will cause the hidden handle to be unable to pop out or be stuck, the micro switch will be damaged, resulting in the door being difficult to open from the outside during rescue, affecting the rescue.

[0051] In addition, after the collision event of the vehicle, if it is in the uphill stage, the vehicle is in the left and right side turning condition; if the door is automatically opened at this time, it will also cause certain danger to the people in the vehicle, for example, the passengers may be more likely to slide out of the vehicle, and then roll down from the steep slope to cause secondary injury.

[0052] Therefore, the present application proposes a control method for a power operated door lock of a vehicle, which comprises:

[0053] Step 100, after receiving the collision signal, running the power operated door collision mode, and recording the vehicle acceleration in real time;

[0054] The running electric vehicle door collision mode includes: step 101, if the vehicle acceleration is zero for a preset time, it indicates that the collision event is over, the electric vehicle door controller 1 shields the micro switch electrical signal, directly controls the electric vehicle door electronic lock 4 to unlock, and then controls the electric door driving mechanism 2 to be powered on to open the door. The preset time can be designed as 5-10s, and the preset time is only an example in the present application, including but not limited to 5-10s; the reason for the preset time is that the vehicle may be temporarily stationary when it reaches a certain position during the rollover process after the collision, and at this time, if the door is opened considering that the collision event is over, there is a certain risk, so calibration design is needed. The above is timed from when the vehicle acceleration is zero to when it is not zero, if the timing time does not exceed the preset time, it is considered that the collision event has not ended, and if it exceeds, it is considered that the collision event has ended.

[0055] Among them, the acquisition of the collision signal is a common technical means in the art, and the judgment or acquisition of the collision signal, that is, how to judge the start of the collision event, is not discussed in the present application. For example, a collision sensor can be set to judge; or the airbag trigger signal of the vehicle airbag control system, the six accelerations and six lateral angles of the vehicle body electronic stability control system or the intelligent driving control system can all be used as the collision signal.

[0056] Through the above setting, a control logic can be designed, and the micro switch signal input is not needed for the closing and opening of the electric vehicle door according to the already set closing and opening of the electric vehicle door. The electric vehicle door can be opened without considering the micro switch signal after the collision, and the electric vehicle door electronic lock 4 is directly unlocked by the program, and then the electric door driving mechanism 2 is powered on to open the door. This process is not affected whether the hidden door handle is intact or damaged, that is, at this time, there is no need to worry that the outer opening handle may be stuck or the micro switch may be damaged due to the collision, and the door does not need to be opened during rescue, which can save rescue time.

[0057] Thus, the problem of hidden handle unable to pop out or stuck due to collision, the door difficult to open from the outside, and the rescue time affected is solved.

[0058] In some preferred embodiments, since the outer opening of the electric vehicle door is mostly in the micro switch mode, when the collision occurs, if the vehicle rolls due to abnormal extrusion, etc., it may cause the micro switch to trigger the electric vehicle door to open, so it is necessary to ensure that the door cannot be opened during the collision process to avoid secondary injury to personnel. Therefore, the automobile electric door lock control method further includes:

[0059] Step 102, if the vehicle acceleration is not zero, it indicates that the collision event has not ended, the electric vehicle door controller 1 shields the micro switch electrical signal, keeps the electric vehicle door electronic lock 4 locked, and keeps the electric door driving mechanism 2 powered off to keep the electric vehicle door closed.

[0060] In some preferred embodiments, before entering the running electric vehicle door collision mode, the following operations are also required:

[0061] The electric vehicle door electronic lock 4 of the vehicle is controlled to release the central locking mode and the child lock mode; this is because the central locking mode and the child lock mode are other modes of the vehicle related to the door, and if these two modes are not released, confusion control will occur.

[0062] That is, the above introduces:

[0063] When a collision occurs

[0064] When a collision occurs, the collision acceleration sensor collects the acceleration of the vehicle and sends it to the vehicle BCM, and when the acceleration value reaches the set collision event threshold, the BCM identifies that the vehicle has a collision accident. At this time, the BCM controls the door lock to release the central state and the child lock state on the one hand; on the other hand, the BCM sends a collision signal to the electric vehicle door controller POD, and the electric vehicle door controller POD shields the electric door opening and closing function, i.e. the micro switch signal, according to the collision signal, to prevent abnormal extrusion during the collision process from causing the electric vehicle door to open, ensuring that passengers can be effectively protected in the passenger compartment and can be protected by seat belts, airbags, seats and other restraint devices.

[0065] When the collision event is complete

[0066] When the collision event is complete, the collision acceleration sensor sensing value will be 0 m / s2, and after a certain period of time, the BCM receives this value and determines that the collision event is complete, and the BCM sends the collision event end information to the electric vehicle door controller POD, which releases the shielding of the electric door function, restores the electric vehicle door function to normal, but directly controls the electric vehicle door electronic lock 4 to unlock, and then controls the electric door driving mechanism 2 to be powered on. In essence, the micro switch signal is also shielded, so that the door is in an open state.

[0067] In some preferred embodiments, in step 101, after the collision event is complete, if the vehicle is in an uphill stage or the vehicle is in a left and right rollover situation; if the door is automatically opened at this time, it will also cause certain danger to the passengers inside the vehicle, for example, the passengers may be more likely to slide out of the vehicle and then roll down from the steep slope, causing secondary injury. In view of this situation, the following settings are made:

[0068] Scheme one:

[0069] Before the step of running the electric vehicle door controller 1 to shield the micro switch electrical signal, directly control the electric vehicle door electronic lock 4 to unlock, and then control the electric door driving mechanism 2 to be powered on to open the door after the collision event, the following steps are further included:

[0070] Obtaining the slope of the vehicle;

[0071] Determining whether the slope is within a predetermined range;

[0072] If yes, the step of running the electric vehicle door controller 1 to shield the micro switch electrical signal, directly control the electric vehicle door electronic lock 4 to unlock, and then control the electric door driving mechanism 2 to be powered on to open the door is executed;

[0073] If no, the step of running the electric vehicle door controller 1 to shield the micro switch electrical signal, keeping the electric vehicle door electronic lock 4 locked, and keeping the electric door driving mechanism 2 powered off to keep the electric vehicle door closed is executed.

[0074] Meanwhile, the whole vehicle slope sensor collects the state of the vehicle and sends the slope information to the electric door controller POD. If the detected slope is within a predetermined range, the electric door controller door lock is unlocked, and the electric door mechanism is driven to open the door to a predetermined angle. At this time, if there is an external rescuer, the external rescuer will be very convenient to open the door, saving the time of opening the door, thereby realizing the valuable rescue action.

[0075] The above can reduce the situation of personnel sliding out after opening the door to a certain extent, but cannot accurately guarantee, because there is no personnel sliding out situation during the current rollover.

[0076] Therefore, in order to further improve the accuracy of control, the following scheme two is provided.

[0077] Scheme two:

[0078] Before the step of running the electric vehicle door controller 1 to shield the micro switch electrical signal, directly control the electric vehicle door electronic lock 4 to unlock, and then control the electric door driving mechanism 2 to be powered on to open the door after the collision event, the following steps are further included:

[0079] Obtaining the slope of the vehicle;

[0080] Determining whether the slope is within a predetermined range;

[0081] If yes, the step of running the electric vehicle door controller 1 to shield the micro switch electrical signal, directly control the electric vehicle door electronic lock 4 to unlock, and then control the electric door driving mechanism 2 to be powered on to open the door is executed;

[0082] If no, the rollover state of the vehicle is first determined;

[0083] When the side turning state is front-back side turning, the step of making the electric vehicle door controller 1 shield the micro switch electric signal, directly controlling the electric vehicle door electronic lock 4 to be unlocked, and then controlling the electric door driving mechanism 2 to be powered on to open the door is executed.

[0084] When the side turning state is left-right side turning, the step of making the electric vehicle door controller 1 shield the micro switch electric signal, keeping the electric vehicle door electronic lock 4 locked, and keeping the electric door driving mechanism 2 powered off to keep the electric vehicle door closed is executed.

[0085] The step of judging the side turning state of the vehicle includes the following steps:

[0086] The heights of the four vehicle wheels are obtained, and the following rules are used for judgment.

[0087] When the height difference of the two front wheels is within the error range, and the heights of the two front wheels are inconsistent with the heights of the two rear wheels, the side turning state of the vehicle is front-back side turning.

[0088] When the height difference of the two front wheels is not within the error range, and the heights of the front and rear wheels on the same side are substantially the same, the side turning state of the vehicle is left-right side turning.

[0089] Through the above control steps, the different side turning states of the vehicle can be recognized, so that corresponding control is performed to avoid the risk of people slipping out after the door is opened.

[0090] Scheme three:

[0091] However, the above scheme two still has certain defects. When the left-right side turning condition is special, i.e. the two doors near the ground are blocked by the ground, if all the doors are executed to be closed, it is obviously not in line with the actual situation, because the doors far from the ground can be opened for rescue.

[0092] Therefore, further, to adapt to the actual situation, the following settings are made:

[0093] When the side turning state is front-back side turning, the electric vehicle door controller 1 is shielded from the micro switch electric signal, all electric vehicle door electronic locks 4 are directly controlled to be unlocked, and then all electric door driving mechanisms 2 are controlled to be powered on to open all doors.

[0094] When the side turning state is left-right side turning, the blocking conditions of all doors are obtained, and then according to the blocking conditions, the step of making the electric vehicle door controller 1 shield the micro switch electric signal, directly controlling the electric vehicle door electronic lock 4 to be unlocked, and then controlling the electric door driving mechanism 2 to be powered on to open the door is executed for the door that is not blocked.

[0095] That is, the two doors on the side close to the ground are blocked by the ground, and the two doors on the side away from the ground perform the opening step.

[0096] The above obtains the blocking situation of all doors, including the following steps:

[0097] Obtain whether an obstacle is detected in the set detection range of the radar sensor on the door, if detected, it indicates that the door where the radar is located is blocked, otherwise it is not blocked;

[0098] Repeat the above steps to obtain the blocking situation of all doors. With the known effect of the radar sensor that can detect obstacles, only the inspection range of the radar sensor needs to be adjusted accordingly.

[0099] The above front and rear side flips refer to: if a road with a slope is taken as a standard, after the side flip, the connecting line between the front and rear of the vehicle is parallel to the center line of the road, it is considered to be a front and rear side flip, at this time the connecting line of the exit formed after the opening of the two side doors is perpendicular to the center line, and the personnel will not slide out;

[0100] If a road with a slope is taken as a standard, after the side flip, the connecting line between the front and rear of the vehicle is perpendicular to the center line of the road, it is considered to be a left and right side flip, at this time the connecting line of the exit formed after the opening of the two side doors is parallel to the center line, and the personnel will slide out. In addition, in the left and right side flips, there are cases where the roof is in contact with the ground and the door is not in contact; and one side of the door is in contact with the ground and the other side is not in contact.

[0101] Through the above steps, a. The risk of opening the electric door during the collision accident is prevented, which may be caused by the abnormal impact of the electric door opening handle switch, the electric door is opened automatically after the collision, which avoids the risk that the outer opening handle is stuck and the door cannot be opened; The electric door is opened automatically after the collision, the rescue personnel can directly implement rescue without thinking about opening the door, which saves valuable time for rescue.
