Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be understood for the present application that the vehicle is directed to a vehicle having a motorized door, the handle of the vehicle being a hidden handle or semi-hidden handle.
The whole system is shown in fig. 1 and 2, and comprises a power door controller 1, a power door driving mechanism 2, a hidden outward opening handle 3 and a power door electronic lock 4.
Conventionally, there are two modes of opening a door from outside the vehicle through an outside-open handle:
First, in a normal case, by pressing the micro switch 301 outside the hidden outward opening handle 3, the electric door controller 1 receives an electric signal from the micro switch 301 at this time, and the electric door controller 1 drives the electric door electronic lock 4 to unlock and supplies power to the electric door driving mechanism 2, so that the electric door driving mechanism 2 realizes automatic opening of the vehicle door.
Second, can pull open hidden outward and open handle 302 too, in the handle rotation process, can trigger a micro-gap switch signal, micro-gap switch signal gives electric door controller 1, and electric door controller 1 can drive electric door electronic lock 4 unblock to the power supply gives electric door actuating mechanism 2, and electric door actuating mechanism 2 realizes the automatic opening of door.
Therefore, the electric vehicle door can be mistakenly touched to generate a micro-switch electric signal in the collision process, that is, the micro-switch electric signal can be sent in a first mode or a second mode in the collision process, for example, the vehicle rolls over, the vehicle is scraped with obstacles on two sides, so that the micro-switch 301 is pressed and stressed, or the micro-switch electric signal is caused by vibration in the collision process, the vehicle door can be opened, and secondary injury is caused to passengers.
In addition, because the hidden handle can not pop out or be blocked due to collision, the micro-switch is crashed, and the door is inconvenient to open from outside the car during rescue, so that rescue is influenced.
In addition, after the collision event of the vehicle is finished, if the vehicle is in an ascending stage and the vehicle is in a left-right side turning condition; if the door is automatically opened at this time, a certain risk is also caused to personnel in the vehicle, for example, passengers may slide out of the vehicle more easily and then roll off a steep slope to cause secondary injury.
Therefore, the application provides a control method of an automobile electric door lock, which comprises the following steps:
Step 100, after receiving a collision signal, operating an electric vehicle door collision mode, and recording the acceleration of the whole vehicle in real time;
Operating the electric vehicle door crash mode includes: and step 101, if the acceleration of the whole vehicle is continuously preset to be zero, indicating that a collision event is finished, enabling the electric vehicle door controller 1 to shield the micro switch electric signal, directly controlling the electric vehicle door electronic lock 4 to be unlocked, and then controlling the electric vehicle door driving mechanism 2 to be electrified so as to open the vehicle door. Wherein the preset time can be designed to be 5-10s, and the preset time is only given as an example in the text, and comprises but is not limited to 5-10s; the reason for the existence of the preset time is that when the vehicle arrives at a certain position in the process of rollover after collision, the vehicle door can be stopped briefly, and if the collision event is considered to be ended and the vehicle door is opened, a certain hidden danger exists, so that calibration design is needed. And (3) counting from the time when the acceleration of the whole vehicle starts to be zero to the time when the acceleration of the whole vehicle does not start to be zero, and if the counted time does not exceed the preset time, the collision event is considered to be not ended, and if the counted time exceeds the preset time, the collision event is considered to be ended.
The acquisition of the collision signal is a common technical means in the field, and the judgment or acquisition of the collision signal, that is, how to judge the start of a collision event is not focused in the application; for example, a collision sensor may be provided for determination; or the airbag triggering signal of the vehicle airbag control system, and six accelerations, six-directional roll angles and the like of the vehicle sent by the vehicle body electronic stability control system or the intelligent driving control system can be used as collision signals.
Through the arrangement, the door can be closed and opened by designing a set of control logic without inputting micro switch signals according to the closing and opening of the set electric door, the micro switch signals are not considered after collision, the electric door electronic lock 4 is directly controlled to unlock through a program, then the electric door driving mechanism 2 is controlled to be electrified so as to open the door, the process is not affected under the condition that the hidden door handle is intact or damaged, that is, the situation that the outward opening handle is blocked or the micro switch is damaged due to collision is not worry, the door is not opened again during rescue, and the rescue time can be saved.
Therefore, the problem that the hidden handle cannot be ejected or jammed due to collision, the car door is inconvenient to open from outside the car, and rescue time is influenced is solved.
In some preferred embodiments, since the electric door is opened by a micro switch mode, when a collision occurs, if the vehicle rolls due to abnormal extrusion, the micro switch may trigger the electric door to open, so that the door is not opened during the collision, and secondary injury caused by personnel is avoided, the control method of the electric door lock of the automobile further includes:
Step 102, if the acceleration of the whole vehicle is not zero, indicating that the collision event is not finished, enabling the electric vehicle door controller 1 to shield the micro switch electric signal, keeping the electric vehicle door electronic lock 4 locked, keeping the electric vehicle door driving mechanism 2 powered off, and keeping the electric vehicle door closed.
In some preferred embodiments, the following operations are also required prior to entering the run electric door crash mode:
The electric door electronic lock 4 of the control vehicle releases the central control lock mode and the child lock mode; this is because the center lock mode and the child lock mode are other modes of the vehicle with respect to the door, and if these two modes are not released, a disorder control occurs.
That is, the above describes:
When collision occurs
When collision occurs, the collision acceleration sensor collects the acceleration of the whole vehicle and sends the acceleration to the whole vehicle BCM, and when the acceleration value reaches a set collision event threshold value, the BCM recognizes that the vehicle has a collision accident. At the moment, the BCM controls the door lock to release the central control state and the child lock state on 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 opening and closing functions of the electric vehicle door, namely the micro switch signal, through software according to the collision signal, so that the electric vehicle door is prevented from being opened due to abnormal extrusion in the collision process, passengers are ensured to be effectively protected in the passenger cabin, and the passengers can be protected by restraining pieces such as safety belts, air bags and seats.
The collision event is completed
When the collision event occurs, the sensing value of the collision acceleration sensor reaches 0m/s 2, after the sensing value lasts for a certain time, the BCM judges that the collision event occurs, the BCM sends the collision event ending information to the electric door controller POD, the POD releases the shielding of the electric door function, the electric door function is recovered to be normal, but the electric door electronic lock 4 is directly controlled to be unlocked, and then the electric door driving mechanism 2 is controlled to be electrified. Essentially shielding the microswitch signal is also performed so that the door is in an open state.
In some preferred embodiments, in step 101, after the collision event occurs, if the vehicle is in an uphill stage and the vehicle is in a side-to-side rollover condition; if the door is automatically opened at this time, a certain risk is also caused to personnel in the vehicle, for example, passengers may slide out of the vehicle more easily and then roll off a steep slope to cause secondary injury. The following settings are made for this case:
scheme one:
after the collision event, the steps of operating the electric door controller 1 to shield the micro switch electric signal, directly controlling the electric door electronic lock 4 to unlock and then controlling the electric door driving mechanism 2 to be electrified to open the door further comprise the following steps:
Acquiring the gradient of the vehicle;
Judging whether the gradient is within a preset range;
If yes, executing the steps of enabling the electric door controller 1 to shield the micro switch electric signal, directly controlling the electric door electronic lock 4 to unlock, and then controlling the electric door driving mechanism 2 to electrify so as to open the door;
if not, the step of shielding the electric signal of the micro switch by the electric door controller 1, keeping the electric door electronic lock 4 locked, keeping the electric door driving mechanism 2 powered off, and keeping the electric door closed is performed.
Meanwhile, the whole vehicle gradient sensor can collect the state of the vehicle and send gradient information to the electric door controller POD, if the detected gradient is in a preset range or the like, the electric door controller door lock is unlocked, and the electric door mechanism is driven to enable the vehicle door to be opened to a preset angle. If external rescue workers exist, the external rescue workers can conveniently open the vehicle door, the time for opening the vehicle door is saved, and therefore precious rescue actions are achieved.
The situation that the personnel slide out after the vehicle door is opened can be reduced to a certain extent, but the situation can not be accurately ensured, and the situation that the personnel slide out does not exist when the vehicle is turned on one's back and forth.
Therefore, in order to further improve the accuracy of the control, there is the following second scheme.
Scheme II:
after the collision event, the steps of operating the electric door controller 1 to shield the micro switch electric signal, directly controlling the electric door electronic lock 4 to unlock and then controlling the electric door driving mechanism 2 to be electrified to open the door further comprise the following steps:
Acquiring the gradient of the vehicle;
Judging whether the gradient is within a preset range;
If yes, executing the steps of enabling the electric door controller 1 to shield the micro switch electric signal, directly controlling the electric door electronic lock 4 to unlock, and then controlling the electric door driving mechanism 2 to electrify so as to open the door;
if not, judging the side turning state of the vehicle;
When the side-turning state is front-back side-turning, executing the steps of enabling the electric vehicle door controller 1 to shield the micro switch electric signal, directly controlling the electric vehicle door electronic lock 4 to unlock, and then controlling the electric vehicle door driving mechanism 2 to electrify so as to open the vehicle door;
When the side-turning state is left-right side-turning, the step of making the electric door controller 1 shield the micro switch electric signal, keeping the electric door electronic lock 4 locked, keeping the electric door driving mechanism 2 powered off to keep the electric door closed is performed.
Wherein, judge the vehicle side turning state and include the following steps:
The height of the four wheels of the vehicle is obtained, and the height is judged according to the following rule;
when the height difference of the two front wheels is in an error range and the heights of the two front wheels are inconsistent with the heights of the two rear wheels, the vehicle is in a side-turning state of front-back side turning;
When the height difference of the two front wheels is not in the error range and the heights of the front wheels and the rear wheels on the same side are approximately the same, the side turning state of the vehicle is left side turning and right side turning.
Through the control steps, different rollover states of the vehicle can be identified, so that corresponding control is performed, and the dangerous condition that a person slips out after opening the door is avoided.
Scheme III:
However, the second scheme has a certain defect, when the left and right side turning situation is special, namely, two doors close to one side of the ground are blocked by the ground, if all the doors execute the closing step, the situation is obviously not in line with the actual situation, and the doors can be opened from two doors far away from one side of the ground to rescue.
Therefore, further, to adapt to the actual situation, the following settings are provided:
When the side-turning state is front-back side-turning, the electric door controller 1 is enabled to shield micro switch electric signals, all electric door electronic locks 4 are directly controlled to be unlocked, and then all electric door driving mechanisms 2 are controlled to be electrified so as to open all doors;
when the side-turning state is left-right side-turning, the shielding condition of all the vehicle doors is obtained, then the vehicle doors which are not shielded are controlled according to the shielding condition to execute the steps of enabling the electric vehicle door controller 1 to shield the micro switch electric signals, directly controlling the electric vehicle door electronic lock 4 to unlock, and then controlling the electric vehicle door driving mechanism 2 to electrify so as to open the vehicle doors.
That is, two doors on the side close to the ground are blocked by the ground, and perform the closing step, and two doors on the side far from the ground perform the opening step.
The shielding condition of all the vehicle doors is obtained, and the method comprises the following steps:
Acquiring whether an obstacle is detected in a set detection range of a radar sensor on a vehicle door, if so, indicating that the vehicle door where the radar is located is shielded, otherwise, not shielding;
Repeating the steps to obtain the shielding condition of all the vehicle doors. The known function of the obstacle can be detected by the radar sensor, and the range of the detection interval of the radar sensor is only required to be correspondingly adjusted.
The front-back rollover refers to: if a road with a gradient is used as a standard, after the vehicle is turned over, a connecting line between the vehicle head and the vehicle tail is parallel to the central line of the road, the vehicle is considered to be turned over forwards and backwards, at the moment, after the vehicle door is opened, the connecting line of an outlet formed after the vehicle doors on two sides are opened is vertical to the central line, and personnel cannot slide out;
If a road with a gradient is used as a standard, after the vehicle is turned over, a connecting line between the vehicle head and the vehicle tail is perpendicular to the central line of the road, the vehicle is considered to be turned over left and right, at the moment, after the vehicle door is opened, the connecting line of an outlet formed after the vehicle doors at two sides are opened is parallel to the central line, and people can slide out. In addition, the left side and the right side are turned over, the roof is in contact with the road ground, and the door is not in contact; and a case in which one side door is in contact with the ground and the other side is not in contact.
Through the steps, a, the risk that the electric door is opened in collision due to the triggering of the inner/outer opening handle switch caused by possible abnormal collision of the electric door when the collision accident happens is prevented; the electric vehicle door is automatically opened after collision, so that the risk that the vehicle door cannot be opened due to the fact that an outward opening handle is blocked and the like is avoided; after the electric car door is in collision, the electric car door is automatically opened, rescue workers can directly rescue the electric car, the user does not need to go to think to open the electric car door, and valuable time is gained for rescue.
