[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0044] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0045] Figure 3 FIG. 1 is a flow chart of a vehicle locking method 300 according to an embodiment of the present disclosure. The execution subject of the method 300 may be a BCM controller, and the method may include:

[0046] Step 310, detecting that the door handle is triggered;

[0047] The door handle may be triggered when the door handle is touched or held. The door may be a driver's door or a co-driver's door.

[0048] When the door handle is triggered, the current, voltage or capacitance of the door will change, thereby ensuring that the triggering of the door handle can be detected in time.

[0049] Step 320, in response to the door handle being triggered, driving the IMMO antenna to work so as to locate the current key position; wherein the scanning range of the IMMO antenna covers the preset keyless entry sensing range of the vehicle, and the preset keyless entry sensing range is the scanning range of the original keyless entry antenna;

[0050] The IMMO antenna is located below the Automobile console (vehicle controller) of the car;

[0051] Since the BCM controller is connected to the driving ends of all antennas in the car, the way to drive the IMMO antenna can be as follows:

[0052] A driving current is provided to the IMMO antenna to enable the IMMO antenna to enter a working state. After the IMMO antenna enters the working state, it will emit a low-frequency signal (such as a 125KHZ low-frequency signal) to the surrounding area with itself as the center, so that the vehicle key will receive the low-frequency signal, and the vehicle's smart key can locate the current position. Therefore, it can give feedback to the BCM based on the low-frequency signal, so that the BCM can confirm the current key position in a timely and accurate manner. In this way, it is convenient to use the current key position to timely drive the door to unlock or lock.

[0053] Secondly, the smart key feeds back a high-frequency signal to the BCM, which carries the current key location. Specifically, the smart key sends a 433.92MHZ high-frequency signal to the corresponding ECU receiving module, and the ECU receiving module then communicates via the CAN bus and sends the corresponding high-frequency signal to the BCM, so that the BCM can extract the current key position from the high-frequency signal.

[0054] In addition, it should be noted that if Figure 2 As shown in the figure, the scanning range of the original IMMO antenna does not include the preset keyless entry sensing range. In order to ensure that the scanning range of the IMMO antenna can cover the preset keyless entry sensing range and avoid canceling the sensing blind area of ​​the vehicle created by the keyless entry antennas on the driver's and co-driver's sides, the driving current of the IMMO antenna can be increased through the BCM, thereby increasing the scanning range of the IMMO antenna by increasing the driving current of the IMMO antenna to ensure that its scanning range can cover the preset keyless entry sensing range. Specifically, the driving current of the IMMO antenna can be increased in the following ways:

[0055] Acquiring a current size of the vehicle and a preset corresponding relationship between the size of the vehicle and a driving current;

[0056] The current size of the vehicle is matched with the preset corresponding relationship to determine the driving current.

[0057] In this way, it can be ensured that the increase in driving current of vehicles of different sizes is different and is best adapted to the vehicle itself.

[0058] Finally, it should be noted that: in order to ensure that the antenna has a scanning blind area / sensing blind area after the original keyless entry antenna is cancelled, and to make the antenna scanning sequence search mechanism more perfect, after driving the IMMO antenna to work, the antenna under the instrument panel can be driven (such as Figure 1 , Figure 2 and Figure 4 The antenna represented by the square on the left side of the IMMO antenna in the figure, where 2UID2 refers to the vehicle key and does not represent the specific location of the vehicle key) and the antenna under the trunk (such as Figure 1 , Figure 2and Figure 4 The antenna represented by the square on the right side of the IMMO antenna, of course, the antenna under the trunk is generally installed under the trunk cover, but sometimes it happens to be the antenna under the second row of seats or the antenna under the third row of seats), and the driving order of the antenna under the instrument panel and the antenna under the trunk is not limited in this disclosure, so as to ensure timely and accurate keyless entry function, and avoid the keyless entry function being mistakenly started due to the presence of a scanning blind spot, such as avoiding the keyless entry function being started when the vehicle is in the vehicle. Among them, the trunk of the vehicle is sometimes called a luggage compartment.

[0059] Step 330, determining whether the current key position is within a preset keyless entry sensing range;

[0060] When determining whether the current key position is within the preset keyless entry sensing range, it is also necessary to determine whether the current key position is within the vehicle to avoid the keyless entry function being mistakenly activated when the key is within the vehicle.

[0061] Step 340, if the current key position is within the preset keyless entry sensing range, obtain the current door lock state;

[0062] Step 350: driving the vehicle door to unlock or lock according to the current door lock state.

[0063] Optionally, in one embodiment, if the current door lock state is that the vehicle doors are unlocked, driving the vehicle doors to lock means driving the four doors to lock; if the current door lock state is that the vehicle doors are locked, driving the vehicle doors to unlock means driving the four doors to unlock, thereby ensuring that the vehicle can be flexibly and accurately controlled to lock or unlock according to the current door lock state.

[0064] After detecting that the vehicle door handle is triggered, the IMMO antenna can be driven immediately to locate the current key position using the IMMO antenna, and after confirming that the current key position is within the preset keyless entry sensing range of the original keyless entry antenna, the current door lock state is obtained, and then the vehicle door is driven to unlock or lock according to the current door lock state. In this way, the keyless entry function can be realized by using the existing IMMO antenna in the vehicle on the basis of eliminating the keyless entry antenna on the driver / passenger side door handle or the door handle side, thereby reducing the complexity of antenna layout and antenna cost in the vehicle. Specifically, the design cost of the keyless entry antenna on the driver / passenger side door handle or the door handle side is saved, and there is no need to glue the wiring harness connecting the keyless entry antenna and fix the fixing bracket / bolt for fixing the keyless entry antenna.

[0065] In some embodiments, in response to the door handle being triggered, driving the IMMO antenna to work so as to locate the current key position includes:

[0066] In response to the door handle being triggered, providing a driving current to the IMMO antenna so that the IMMO antenna enters a working state, wherein after the IMMO antenna enters the working state, a low-frequency signal is transmitted to the vehicle key to locate the current key position;

[0067] A high-frequency signal is received which is sent by the vehicle key via a CAN bus, wherein the high-frequency signal carries the current key position.

[0068] The IMMO antenna is located below the Automobile console in the vehicle;

[0069] Since the BCM controller is connected to the driving ends of all antennas in the car, the way to drive the IMMO antenna is as follows:

[0070] A driving current is provided to the IMMO antenna to put the IMMO antenna into working state. After the IMMO antenna enters the working state, it will emit a low-frequency signal (such as a 125KHZ low-frequency signal) to the surrounding area with itself as the center, so that the vehicle key will receive the low-frequency signal, and the vehicle's smart key can locate the current position. Therefore, it can give feedback to the BCM based on the low-frequency signal, so that the BCM control can timely and accurately confirm the current key position. In this way, it is convenient to use the current key position to timely drive the door to unlock or lock.

[0071] The high-frequency signal that the smart key feeds back to the BCM is sent through the CAN bus. The high-frequency signal carries the current key location. Specifically, the smart key will send a 433.92MHZ high-frequency signal to the corresponding ECU receiving module, and the ECU receiving module will then communicate through the CAN bus and send the corresponding high-frequency signal to the BCM, so that the BCM can extract the current key position from the high-frequency signal, which is convenient for accurately judging whether the current key position is within the preset keyless entry sensing range.

[0072] In some embodiments, before providing a driving current to the IMMO antenna in response to the door handle being triggered, the method further includes:

[0073] Acquiring a current size of the vehicle and a preset corresponding relationship between the size of the vehicle and a driving current;

[0074] The size of a vehicle refers to the size of the vehicle model, which may be the size of the wheelbase.

[0075] The current size of the vehicle is matched with the preset corresponding relationship to determine the driving current.

[0076] Through this embodiment, the driving current can be adaptively increased according to the current size of the vehicle to ensure that the driving current is best matched to the vehicle itself and to ensure that the driving current of the increased IMMO antenna can cover the preset keyless entry sensing range.

[0077] Since antennas influence each other, when adjusting the driving current of the IMMO antenna, other antennas in the car can be adjusted at the same time, such as the antenna under the trunk and the driving current of the antenna under the dashboard, so as to ensure that there are no blind spots in the scanning range of the antenna in the car and achieve accurate positioning of the key.

[0078] The method of adjusting other antennas can be the same as the method of adjusting the driving current of the IMMO antenna, that is, the current size of the vehicle can be matched with the preset correspondence to determine the driving current of the other antennas. In this case, the preset correspondence includes not only the correspondence between the current size of the vehicle and the driving current of the IMMO antenna, but also the current size of the vehicle and the driving current of the other antennas, as shown in Table 1. The antenna under the center storage box in Table 1 is the IMMO antenna, and the current value corresponding to the Step field in Table 1 is the driving current value. It can be seen from Table 1 that there is a corresponding relationship between the driving currents of the antenna under the center storage box, the antenna under the dashboard, and the antenna at the trunk. The Step values ​​of the three antennas can be adjusted together according to the current size, thereby adjusting the driving currents of the three antennas.

[0079] Table 1

[0080]

[0081] In some embodiments, the driving of the IMMO antenna to locate the current key position includes:

[0082] After driving the IMMO antenna to work, the antenna under the instrument panel and the antenna under the trunk are driven in sequence to work, so as to locate the current key position;

[0083] After driving the IMMO antenna to work, the antenna under the trunk and the antenna under the instrument panel are driven to work in turn to locate the current key position, wherein the scanning range of the antenna under the trunk is a first area in the car, the scanning range of the antenna under the instrument panel is a second area in the car, and the scanning range of the IMMO antenna is a third area in the car and the preset keyless entry sensing range, and the first area, the second area and the third area intersect with each other.

[0084] The scanning ranges of the IMMO antenna, the antenna under the driver's instrument panel and the antenna under the trunk intersect with each other, and the scanning range of the IMMO antenna not only covers part of the area inside the vehicle but also covers the preset keyless entry sensing range. Therefore, it can be ensured that there are no blind spots in the scanning range and the key can be accurately positioned.

[0085] In some embodiments,

[0086] If the current key position is within the preset keyless entry sensing range, obtaining the current door lock state includes:

[0087] If the current key position is not in the vehicle and is located within the preset keyless entry sensing range, the current door lock state is obtained.

[0088] Since the smart key is in the car or has not entered the preset keyless entry sensing range, it is not suitable to realize the keyless entry function. Therefore, when judging whether the current key position is in the preset keyless entry sensing range, it is also necessary to judge whether the current key position is in the car. Only when the current key position is not in the car and is in the preset keyless entry sensing range, the current door lock status is obtained to avoid the keyless entry function being mistakenly activated when the key is in the car or not in the preset keyless entry sensing range.

[0089] In some embodiments, the driving the vehicle door to unlock or lock according to the current door lock state includes:

[0090] If the current door lock state is that the door is unlocked, driving the door to lock;

[0091] If the current door lock state is that the vehicle door is locked, the vehicle door is driven to be unlocked.

[0092] If the current door lock state is that the vehicle doors are unlocked, driving the vehicle doors to lock means driving the four doors to lock; if the current door lock state is that the vehicle doors are locked, driving the vehicle doors to unlock means driving the four doors to unlock, thereby ensuring that the vehicle can be flexibly and accurately controlled to lock or unlock according to the current door lock state.

[0093] It should be noted that, for the aforementioned method embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should be aware that the present disclosure is not limited by the order of the actions described, because according to the present disclosure, certain steps can be performed in other orders or simultaneously.
