Fig. 1 is a schematic flow chart of a vehicle unlocking method according to an embodiment of the present application. The embodiment of the application provides a vehicle unlocking method, which further comprises an intelligent terminal (such as a mobile phone) and a vehicle, wherein the vehicle performs unlocking action on the vehicle by acquiring signals sent by the intelligent terminal. The implementation steps of the specific vehicle unlocking method comprise:
s1, acquiring an intensity signal between the intelligent terminal and the vehicle.
S2, performing first filtering and second filtering on the intensity signals to obtain first filtering data and second filtering data.
And S3, determining the area information of the intelligent terminal according to the first filtering data, and determining the trend information of the vehicle and the intelligent terminal according to the second filtering data.
S4, the region information and the trend information are combined, an unlocking signal of the vehicle is determined, unlocking action is carried out on the vehicle according to the vehicle unlocking signal, or a locking signal of the vehicle is determined, and locking action is carried out on the vehicle according to the vehicle locking signal.
According to the vehicle unlocking and locking method, the intensity signal is obtained, the first filtering and the second filtering are carried out on the intensity signal to obtain and determine the area information and the trend information, and then the area information and the trend information are combined, so that shaking of the vehicle unlocking and locking signal in the transmission process is relieved, delay of the vehicle when a vehicle unlocking and locking operation instruction is received is reduced, and accordingly response sensitivity of the vehicle is improved.
Optionally, a plurality of antennas are disposed on the vehicle, where the plurality of antennas are disposed on a left door, a right door, a rear tail and a center console of the vehicle, respectively, and the intelligent terminal sends an intensity signal to the vehicle, and receives the intensity signal by the antennas disposed on the left door, the right door, the rear tail and the center console of the vehicle, where in this embodiment, the intensity signal may refer to signals obtained by antennas disposed at different positions of the left, right, rear and center.
Optionally, the trend of the intelligent terminal in the area or approaching or separating from the vehicle can be judged by acquiring a certain time length and acquiring intensity signals received by the left door, the right door, the rear tail and the center console 4 directions of the vehicle.
Optionally, the first filtering is SG filtering, and the second filtering is Kalman filtering.
In this embodiment, two kinds of filtering data can be obtained by Kalman filtering and SG filtering, and the trend change of signal stability can be obtained by using Kalman filtering, so that the anti-jitter performance of the signal is better, but the delay is larger, the signal intensity information is more lost, and the better signal intensity information and sensitivity can be kept by using SG filtering, but the anti-jitter performance is not good. Therefore, the data complementation is carried out by combining Kalman filtering and SG filtering, so that the data signals with high stability and high sensitivity are obtained, shake of the vehicle unlocking signal in the transmission process is relieved, and delay of the vehicle when receiving the vehicle unlocking operation instruction is reduced.
Optionally, the first filtering and the second filtering may be performed simultaneously or separately, and when the area determination is performed, processing means such as time buffering and space buffering may be further performed, so as to quickly identify that the intelligent terminal is in the area.
Optionally, the area information includes an in-vehicle area and an out-vehicle area, wherein the out-vehicle area further includes a vehicle unlocking area, a vehicle unlocking buffer area and a vehicle locking area.
Optionally, when the intelligent terminal is judged to be slowly approaching the vehicle, the signal filtered by Kalman is very stable and changes very slowly, trend information can be judged according to the time interval signal difference, if no change exists between the vehicle and the intelligent terminal, the trend information indicates no trend, if the change exists between the vehicle and the intelligent terminal, the trend information indicates approaching trend, and when the signal filtered by SG generates clear change (the signal becomes stronger in fluctuation), the area information can be judged to be an unlocking area when the strength of the signal exceeds a preset boundary value. For example: the user holds the intelligent terminal close to the left door, and then the finally executed action is unlocking of the left door of the vehicle.
Alternatively, the joint region information and trend information may be processed using an or relationship.
Optionally, a vehicle unlocking method provided in an embodiment of the present application includes:
s31, judging whether the first filtering data meets preset intensity;
and S32, if the information is satisfied, determining that the intelligent terminal is in the out-of-vehicle area.
Optionally, when the intelligent terminal is in an off-vehicle area, as shown in fig. 2, a schematic flow chart of steps S33 to S36 in the vehicle unlocking method provided in the embodiment of the application is shown. The method comprises the following steps:
s33, judging whether the first filtering data meets the preset intensity of the unlocking zone of the vehicle.
And S34, if the vehicle unlocking area is met, determining that the intelligent terminal is in the vehicle unlocking area.
And S35, if not, judging whether the first filtering data meets the preset strength of the vehicle locking area.

Optionally, when the first filtering data cannot meet the preset intensity of the vehicle unlocking zone and the preset intensity of the vehicle locking zone, acquiring at least 2 times of the first filtering data in the preset time, judging whether the at least 2 times of the first filtering data meet the preset intensity of the vehicle unlocking buffer zone, and if so, determining that the intelligent terminal is in the vehicle unlocking buffer zone.
In this embodiment, the first filtering data includes: the central control signal, the left signal, the right signal and the tail signal determine that the intelligent terminal is in an off-vehicle area, and whether the central control signal or the left signal, the right signal and the tail signal are smaller than preset intensity can be judged.
For example: the central control signal > -50db or the left signal and the right signal > -70db is judged that the intelligent terminal is in the in-vehicle area; otherwise, the central control signal < -55db or the left signal and the right signal < -75db are judged to be the vehicle exterior region. In this embodiment, the preset intensity or boundary value may be-50 db, -70db, -75db.
Also for example: when the rear tail signal > max (left handle signal, right door handle signal) +5db is judged as the rear region; otherwise, when the tail signal < max (left handle signal, right handle signal) +0db is determined as the left area or the right area, in this embodiment, the preset intensities are not the same value, there is a difference between the preset intensities, and the difference information is mapped onto the physical space so as to correspond to the unlock area or the lock area in the area information.
Or, when the left signal > -75db is judged as the left unlock region; otherwise, when the left signal < -80db is judged to be a locking area, at the moment, the-75 db and the-80 db are preset intensities, and a difference of 5db exists between the two signals, the two signals are mapped to a physical space, and the two signals correspond to the unlocking buffer area.
In this embodiment, by setting different preset intensities or boundary values, a difference exists between the preset intensities, and a buffer area is established by using difference information, so as to ease interference caused by signal jitter.
Fig. 3 is a schematic flow chart of steps S37 to S312 in a vehicle unlocking method according to an embodiment of the present application. The embodiment of the application provides a vehicle unlocking method, which comprises the following steps:
s37, at least two second filtering data of preset time are acquired.
And S38, summing the second filtering data to obtain current summation data.
S39, obtaining summation data of the last preset time, and calculating a difference value between the current summation data and the summation data of the last preset time to obtain trend data.
S310, judging whether the trend data is larger than preset trend data.
And S311, when the trend data is larger than the preset trend data, determining the trend information as a trend approaching the vehicle.
And S312, when the trend data is smaller than the preset trend data, determining the trend information as far away from the trend of the vehicle.
In this embodiment, after the second filtering data is obtained, data acquisition can be performed on the left signal, the right signal, the tail signal and the central control signal every 10s, statistical summation is performed, then the current 10s data and the 10s previous data are used for making a difference, and when the difference value is greater than 5db, the approaching trend is determined; when the difference is smaller than-5 db, the trend is judged to be far away from the trend, and the difference is between-5 db and 5db, the trend is judged to be a buffer zone, and no judgment is made.
Optionally, when the area information includes a vehicle unlocking area and a vehicle locking area, and the trend information includes a trend approaching the vehicle and a trend separating from the vehicle, the area information and the trend information are combined to determine an unlocking signal of the vehicle, and perform an unlocking action on the vehicle according to the vehicle unlocking signal, or determine a locking signal of the vehicle, and perform a locking action on the vehicle according to the vehicle locking signal, including:
when the area information is a vehicle unlocking area or the trend information is a trend of approaching the vehicle, acquiring a vehicle unlocking signal, and executing unlocking action on the vehicle according to the vehicle unlocking signal;
when the regional information is a vehicle locking region or the trend information is a trend away from the vehicle, acquiring a vehicle locking signal, and executing locking action on the vehicle according to the vehicle locking signal.
Optionally, before the intensity signal between the intelligent terminal and the vehicle is obtained, setting the collection time of the intensity signal and the collection range of the intensity signal are further included.
In this embodiment, the vehicle unlocking method is executed, and the intelligent terminal is required to be matched with the vehicle, or the collection time of the intensity signal and the collection range of the intensity signal are set, which specifically may be that the collection distance and the collection time of the collection point are calibrated by using the intelligent terminal. For example, the acquisition point may be that antennas are arranged at the left door, the right door, the rear tail and the center console of the vehicle to acquire signals, the acquisition time is set to 30 seconds per point, and the signal acquisition is sequentially or synchronously performed, wherein the acquisition distance may be set to be 1 meter or 7 meters in the vertical direction of the outer handle of the left door, and 1 meter or 7 meters in the vertical direction of the outer tail door.
According to the vehicle unlocking and locking method, the intensity signal is obtained, the first filtering and the second filtering are carried out on the intensity signal to obtain and determine the area information and the trend information, and then the area information and the trend information are combined, so that the vehicle unlocking and locking signal is easy to shake in the transmission process, delay of a vehicle when receiving a vehicle unlocking and locking operation instruction is reduced, and the response sensitivity of the vehicle is improved.
In this embodiment, the vehicle unlocking method is implemented, and the required device includes: the vehicle comprises a vehicle and an intelligent terminal (mobile phone), wherein the left door, the right door, the rear tail and the center console of the vehicle are respectively provided with an antenna for collecting intensity signals sent by the intelligent terminal, the antennas transmit the corresponding intensity signals to the vehicle control terminal after collecting the intensity signals, and the vehicle unlocking method is implemented by the vehicle control terminal.
When the intelligent terminal slowly approaches the vehicle from outside the vehicle, an antenna on the vehicle receives an intensity signal sent by the intelligent terminal and sends the intensity signal to a vehicle control terminal, the vehicle control terminal receives the intensity signal, the intensity signal performs SG filtering and Kalman filtering, the signal obtained by the Kalman filtering is very stable under the condition, the signal change is very slow, trend information can be judged by using the Kalman filtering and time interval signal difference, the trend information is no trend at this moment, on the contrary, the signal obtained by the SG filtering can generate clear change (the signal becomes strong in fluctuation), when the intensity exceeds a preset boundary value in a corresponding area, and an area judgment flow can obtain an unlocking area, for example: the intelligent terminal approaches from the left door, and outputs a left unlocking zone after the intensity signal is filtered by the SG. The results are completely different by processing the same intensity signals using SG filtering and Kalman filtering, which considers that there is no trend between the vehicle and the intelligent terminal at this time, while SG filtering considers that the intelligent terminal is within the left unlock region of the vehicle, thus outputting a "left unlock region". In order to achieve the advantages of 2 kinds of filtering, in this embodiment, the SG filtering and the Kalman filtering are combined, and the or relationship is adopted to process the unlocking result of the vehicle. Namely, the unlocking judgment is output after OR logic processing is carried out on the 'no trend' and the 'left unlocking zone'. In this case, the SG filtered region judgment works better than the Kalman filtered trend judgment.
When the intelligent terminal rapidly approaches the vehicle from outside the vehicle, an antenna on the vehicle receives an intensity signal sent by the intelligent terminal and sends the intensity signal to a vehicle control terminal, the vehicle control terminal receives the intensity signal, and the intensity signal performs SG filtering and Kalman filtering. In the conventional deblocking method, in the SG filtered regional information judgment, a buffer is present in a blocking area and a deblocking area due to the upper and lower bounds of a preset boundary value, and when the intelligent terminal is in the buffer, the regional judgment flow cannot judge the result, so that the reason is that: in the judgment logic, the unlocking area or the locking area is distinguished only according to the same value comparison, and the repeated transverse jump of the unlocking area can occur only because the spatial distribution of the intensity signals in the actual environment is very unstable, so that the user experience is reduced. In order to solve the above problem, the repeated cross jump of the unlocking area is solved by adding the space buffer, which may cause the delay of the area decision process (i.e. a section of signal area is wasted and cannot be used), in addition, in this case, in order to better solve the unstable distribution of the signal in the time dimension, a buffer in the time dimension is further provided, for example: and determining effective judgment only when the area judgment results of the continuous preset frame signals are consistent. Another example is: in order to cope with the buffer area introduced by jitter in signal space-time, delay of decision tree judgment flow is obviously increased, when a person approaches the car from a distance quickly, due to the delay, the person needs to wait when the person walks to a position close to the car and even walks to the car side, the waiting algorithm is needed to judge to finish giving an unlocking area, the car can be unlocked, and the user experience is also poor.
In this embodiment, since the trend determination after Kalman filtering is very stable, no buffer in space or time is needed at this time, when a person approaches from a distant place and is still in the buffer in the middle of unlocking, the trend determination flow is likely to be able to make a determination of the approach trend, and at this time, the flow of region information determination is also able to give a prompt that cannot be determined, so in this embodiment, the unlocking result of the vehicle is processed by adopting an or relationship. Namely, after OR logic processing is carried out on the 'unable judgment' and the 'approaching trend', an unlocking judgment unlocking result is output. In this case, the region judgment of the Kalman filter functions better than the trend judgment of the SG filter.
By analyzing the scene of approaching the vehicle through the intelligent terminal, it can be known that when the region judgment under the SG filtering is still in the condition that the judgment can not be performed by using the method provided by the embodiment, the trend judgment under the Kalman filtering can be performed in advance, and when the trend judgment under the Kalman filtering is in the condition that the trend judgment under the SG filtering is not in the condition that the trend judgment under the SG filtering is performed in advance. And meanwhile, two types of filtering are used for complementation, so that the vehicle unlocking method is more sensitive and stable, and the user experience is further enhanced.
