In this embodiment, the communication state of the digital key antenna is used to indicate whether the communication connection between the digital key antenna and the digital key controller is normal. Optionally, the digital key controller acquires the communication state of the digital key antenna according to the detection period, or acquires the communication state of the digital key antenna when detecting that the digital key is close to any one control object, wherein the digital key is close to any one control object refers to at least one digital signal sent by the digital key detected by the digital key antenna.
In an alternative embodiment, a method of acquiring a communication state of a digital key antenna includes:
And acquiring a digital pairing signal sent by the digital key antenna, and judging whether the digital communication of the digital key antenna is in a digital communication failure state or not based on the digital pairing signal. Acquiring a CAN communication signal sent by the digital key antenna, judging whether CAN communication of the digital key antenna is in a CAN communication failure state based on the CAN communication signal, and if the digital key antenna meets the following conditions: at least one of being in the CAN communication disabled state or being in the bluetooth communication disabled state, determining that the communication state of the digital key antenna is in an abnormal state.
S202, if at least one digital key antenna exists and the communication state is in an abnormal state, acquiring a new control area of the control object.
In this embodiment, the new control area of the control object overlaps with the original control area of the control object, and the new control area of the control object is larger than the original control area of the control object.
According to the technical scheme, in the control area acquisition method provided by the embodiment of the application, the digital key controller acquires the communication state of the digital key antenna, and if at least one communication state of the digital key antenna is in an abnormal state, a new control area of a control object is acquired. Because the new control area of the control object is overlapped with the original control area of the control object and the new control area of the control object is larger than the original control area of the control object, the control area of the control object is enlarged when the communication state of at least one digital key antenna is in an abnormal state, so that the control accuracy of the control object is improved and the user experience is improved.
An optional application scenario of the control region acquisition method provided by the embodiment of the application is as follows:
The digital key controller is a Bluetooth key controller, the digital key is a Bluetooth key, the digital key antenna is a Bluetooth antenna, and the control object is a vehicle door. Under this application scenario, bluetooth key controller receives the bluetooth signal that bluetooth key sent and based on bluetooth signal, discerns bluetooth key's position to confirm the control area that bluetooth key was located based on bluetooth key's position, realize the unlocking control to the door that control area corresponds. The control area is one of a plurality of original control areas, and in the prior art, the original control areas are configured for all vehicle doors in advance to realize the fine division of the surrounding areas of the vehicle, so that the unlocking control of the vehicle is realized in a targeted manner.
Taking the original control area of the vehicle door shown in fig. 1 as an example, the original control area of the vehicle door on the main driving side includes an area 1 and an area 2, the original control area of the vehicle door on the assistant driving side includes an area 2, the original control area of the back door includes an area 3, the bluetooth key controller receives a plurality of bluetooth signals sent by the bluetooth key through a plurality of bluetooth antennas (configured at a preset position of the vehicle, not shown in fig. 1), and when determining that the bluetooth key is in the area 1 based on the plurality of bluetooth signals, unlocking control of the two vehicle doors on the main driving side of the vehicle is realized. When the Bluetooth key is determined to be in the area 2, four-door unlocking control on two sides of the vehicle is realized, and when the Bluetooth key is determined to be in the area 3, back door unlocking control is realized. In this embodiment, the unlocking control means to enter a triggerable unlocking state or to enter an unlocking state. Optionally, in the triggerable unlocking state, the sensor configured at the door sends the collected door opening signal (such as a pressure signal or an image signal) to the bluetooth key controller, and in the triggerable unlocking state, the bluetooth key controller sends an unlocking instruction of the door to the door lock controller, so that the door lock controller performs unlocking operation on the door based on the unlocking instruction. Or in the unlocking state, the vehicle door is unlocked and can be directly opened.
Under some limit working conditions (for example, surrounding metal buildings are more, vehicles in a parking lot are denser, and the like), due to certain deviation of the positioning capability of Bluetooth signals, the Bluetooth key controller is inaccurate in positioning of Bluetooth keys, at this time, unlocking control on a vehicle door based on original control area division cannot be realized, and poor user experience is caused. For example, because the bluetooth signal is weaker, the actual position of the bluetooth key is in region 2, and the result of the bluetooth key controller locating the bluetooth key indicates that the position of the bluetooth key is in region 3, at this time, unlocking control of the main driving side door cannot be achieved based on the bluetooth key.
In general, the reason for inaccurate positioning of the bluetooth key by the bluetooth key controller is that bluetooth signal receiving and transmitting of the bluetooth antenna is abnormal, for example, at least one bluetooth antenna is in a failure state, and in the failure state, the bluetooth antenna cannot receive a bluetooth signal sent by the bluetooth key, or cannot send the received bluetooth signal to the digital key controller. Therefore, in the control area acquisition method provided by the embodiment of the application, when at least one antenna is in the failure state, the redundancy mode is started to control the vehicle door by the new control area, and because the fineness of the new control area is lower than that of the initial control area, the control area acquisition method is optimized, and the user experience is improved.
The control area acquisition method provided by the embodiment of the application is applied to, but not limited to, a vehicle door control system shown in fig. 3, and as shown in fig. 3, the vehicle door control system comprises a multimedia host, a Bluetooth key controller, a Bluetooth antenna and a Bluetooth key, wherein the Bluetooth key and the Bluetooth antenna pre-construct Bluetooth communication, and the Bluetooth key controller and the Bluetooth antenna pre-construct Bluetooth communication and CAN communication.
In this embodiment, the bluetooth key controller is configured in the vehicle control system, and is disposed on a central axis (below the auxiliary dashboard) inside the vehicle, the bluetooth antenna is configured at a preset position of the vehicle, for example, the number of bluetooth antennas is n=4, and the bluetooth key is a bluetooth module configured in an intelligent mobile device (for example, a smart phone, a smart watch, or a smart bracelet), and it is noted that the bluetooth key, the bluetooth antenna, and the bluetooth key controller are pre-configured through the intelligent mobile device for secure communication, that is, the bluetooth key is pre-activated, and a specific method for activating the bluetooth key can be seen in the prior art.

For any one of the Bluetooth antennas, if a Bluetooth pairing signal sent by the Bluetooth antenna is not received in a preset first time period, or the received Bluetooth pairing signal sent by the Bluetooth antenna does not meet a preset first pairing condition, determining that the Bluetooth antenna is in a Bluetooth communication failure state. The first time period refers to a time period corresponding to a Bluetooth pairing signal sending period. The first pairing condition refers to a pairing condition of the bluetooth pairing signal, for example, including a verification field for a predetermined agreement.
S402, acquiring a CAN communication signal sent by the Bluetooth antenna, and judging whether CAN communication of the Bluetooth antenna is in a CAN communication failure state or not based on the CAN communication signal.
For any one Bluetooth antenna, if the CAN communication signal sent by the Bluetooth antenna is not received within a preset second time period, or the received CAN communication signal sent by the Bluetooth antenna does not meet a preset second pairing condition, determining that the Bluetooth antenna is in a CAN communication failure state. The second time period refers to a time period corresponding to the transmission period of the CAN communication signal. The second pairing condition refers to a pairing condition of the CAN communication signal, for example, including a verification field for a predetermined agreement.
S403, if the bluetooth antenna satisfies: at least one of being in the CAN communication disabled state or being in the bluetooth communication disabled state, determining that the communication state of the bluetooth antenna is in an abnormal state.
S404, if the communication state of at least one Bluetooth antenna is in an abnormal state, acquiring a new control area of the vehicle door.
In this embodiment, the new control area of the door overlaps the original control area of the door, and the new control area of the door is larger than the original control area of the door.
Specifically, there is a bluetooth key in a pairing abnormal state, and the bluetooth key controller starts a redundancy mode. And under the redundancy mode, optimizing the control area of each vehicle door based on the original area division result to obtain an area re-division result, wherein the original area division result comprises the original control area of each vehicle door, and the area re-division result comprises the new control area of each vehicle door. As illustrated in fig. 4b, a schematic diagram of the area repartition result is illustrated, where the area 4 is a new control area of each door, that is, the new control area overlaps with the areas 1,2, and 3, respectively, and the area of the new control area is larger than the areas 1,2, and 3. For the main drive door, the original control area includes area 1 and area 2, and the new control area includes area 4, it being apparent that the new control area of the main drive door satisfies that there is overlap with area 1 and area 2 and is greater than area 2 and area 3.
The method for obtaining the new control area of any one door includes various methods, and an optional method includes:
A1, acquiring a target original control area set of the vehicle door.
In this embodiment, the set of target raw control regions includes at least one target raw control region, the target raw control region includes a plurality of raw control regions, for example, the raw control region of the first door includes a first region, a second region, a third region, and a fourth region, wherein the first region and the second region are adjacent, the third region and the fourth region are adjacent, the raw control region of the first door is divided into 2 groups of target raw control regions, the first group of target raw control regions includes the first region and the second region, and the second group of target raw control regions includes the third region and the fourth region.
A2, constructing a communication area covering each original control area in the target original control area for the target original control area.
For example, for a first set of target raw control regions, a first communication region is constructed that covers the first region and the second region. For the second set of target original control regions, a second communication region covering the third region and the fourth region is constructed, and it should be noted that specific methods for constructing the communication region covering the plurality of regions include various methods, for example, constructing a circular communication region with the farthest distance between the plurality of regions and the first door as a radius, and with the first door dot.
A3, acquiring a new control area of the vehicle door based on the communication area corresponding to the target original control area.
In this embodiment, for a plurality of groups of target original control areas, after the communication areas corresponding to the target original control areas are obtained, each communication area is used as a new control area of the vehicle door.

According to the control area acquisition method provided by the embodiment of the application, the Bluetooth key controller completes state monitoring of the Bluetooth antennas based on CAN communication and Bluetooth communication, when at least one Bluetooth antenna is in an abnormal state, new control areas of all doors are acquired, and because the new control areas are larger than the original control areas and overlap with the original control areas, the repartition of the control areas of the doors when the communication state of the Bluetooth antenna is abnormal is realized, and the accuracy of unlocking control of the Bluetooth key controller on the doors is improved by reducing the fineness of the area division, so that the user experience is improved.
Further, based on the Bluetooth pairing signals and the CAN communication signals sent by the Bluetooth antennas, whether the Bluetooth antennas are in an abnormal state or not is judged, accuracy of judging results of whether the communication states are abnormal or not is improved, and reliability of vehicle door control is further improved. Specifically, the condition that the redundancy mode is turned on is that the bluetooth key controller determines that the connection pairing state of any bluetooth antenna and bluetooth key is invalid based on the combination of the CAN communication and the bluetooth communication, that is, the bluetooth antenna and the bluetooth key are in a pairing abnormal state. The situation that CAN communication and Bluetooth communication are unstable is avoided, and the probability of entering a redundancy mode by mistake is reduced.
It should be noted that the above embodiments are only alternative specific embodiments of a control area acquisition method provided in the embodiments of the present application.
For example, S401 to S403 are an optional method for acquiring a communication state of a bluetooth antenna, and in another optional embodiment, the detection of the communication state may be performed based on a pairing signal between any one or more bluetooth antennas and a bluetooth key controller.
For another example, in another alternative embodiment, A1-A3 may be implemented by a multimedia host, that is, the bluetooth key controller enters a redundancy mode when there is an abnormal state of the bluetooth antenna, and sends a redundancy mode starting instruction to the multimedia host, and the multimedia host executes A1-A3 and feeds back a new control area of each door to the bluetooth key controller. Or the multimedia host computer configures the new control area of each car door in advance, and feeds back the pre-stored new control area of each car door to the Bluetooth key controller after receiving the redundant mode starting instruction sent by the Bluetooth key controller.
