Like elements in the various figures are denoted by the same or similar reference numerals. For purposes of clarity, the various features in the drawings are not necessarily drawn to scale. Moreover, certain well-known elements may not be shown in the figures.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure of the present application unless the context clearly dictates otherwise. For clarity of description of particular embodiments, only an exemplary illustration of some terms is given below.

Term(s) for

The "smart terminal" includes, but is not limited to, a mobile phone, a Personal Digital Assistant (PDA), a smart watch, smart glasses, a smart band, a smart terminal, and other portable smart terminals.

The "unlock/lock area" refers to a specific area defined around the vehicle, in which the vehicle enters the area, and the vehicle is automatically locked when the vehicle leaves the area.

The "activation zone" is a specific area defined around the vehicle within which the vehicle can be activated by a single key or brought into a standby power-up state, and the user can power up the vehicle by, for example, stepping on the brakes.

Various aspects of the invention are described in detail below with reference to the figures and examples. Fig. 1 is a schematic diagram of a vehicle and a smart terminal provided according to the prior art. FIG. 2 is a flow chart of a prior art vehicle unlocking scheme.

And step S01, the intelligent terminal and the vehicle establish Bluetooth connection.

And S02, continuously acquiring the RSSI through the Bluetooth module, and calculating the distance between the intelligent terminal and the intelligent terminal according to the RSSI.

And step S03, judging the position relation between the intelligent terminal and the vehicle according to the distance.

Step S04 is that if the intelligent terminal enters the area limited by the PS, the vehicle can be started by one key or enters a state to be powered on, and if the intelligent terminal leaves the area of the PS, the vehicle cannot be started by one key without a key or enters the state to be powered on.

And step S05, if the vehicle enters the area limited by the PE, unlocking the vehicle, and if the vehicle leaves the area limited by the PE, automatically powering off the vehicle and turning off the vehicle and locking the vehicle.

According to the starting and unlocking scheme in the prior art, a bluetooth module is arranged in the intelligent terminal 101, a bluetooth module is also arranged in the vehicle 102, when a user holds the intelligent terminal 101 to approach the vehicle 102 and the distance between the intelligent terminal 101 and the vehicle 102 is equal to RKE (remote control area), the intelligent terminal 101 and the vehicle 102 are connected through the bluetooth module, usually, pairing information needs to be exchanged and stored locally when the bluetooth connection is established between the intelligent terminal 101 and the vehicle 102 for the first time, the bluetooth connection can be quickly reestablished by subsequently multiplexing the local pairing information, and the pairing information can comprise identification marks, communication keys and the like of the two parties. In the process of establishing the Bluetooth connection for the first time, the two parties can check the identity of the other party respectively, and after the check is passed, pairing information is generated locally respectively.

After the bluetooth connection is completed, the bluetooth module of the intelligent terminal 101 detects a bluetooth Signal Strength RSSI (Received Signal Strength Indication) in real time, the intelligent terminal 101 determines a distance between the vehicle 102 and the intelligent terminal 101 through the RSSI, when the distance between the intelligent terminal 101 and the vehicle 102 is shortened to PE (for example, 3 m), the bluetooth module of the intelligent terminal 101 sends an unlocking command to the vehicle 102, after the vehicle receives the command, the unlocking is completed, when the distance between the intelligent terminal 101 and the vehicle 102 is shortened to PS (for example, 1 m), the bluetooth module of the intelligent terminal 101 sends a starting command to the vehicle 102, after the vehicle receives the starting command, the vehicle can be started by one key without a key or enter a state to be powered on, and a user can power on the vehicle by stepping on a brake, for example. This process is very convenient for the user to operate. When the vehicle 102 is used, the bluetooth module on the intelligent terminal 101 detects the bluetooth signal strength RSSI in real time, and determines the distance between the vehicle 102 and the intelligent terminal 101 according to the RSSI, when the intelligent terminal 101 leaves the vehicle 102 to a certain distance PS (for example, 1 m), the vehicle cannot be started without a key or enters a state to be powered on, a user can power on the vehicle by stepping on a brake, for example, and when the intelligent terminal 101 leaves the vehicle 102 to a certain distance PE (for example, 3 m), a vehicle locking command is sent to the vehicle 102, and the vehicle is automatically locked.

Fig. 3 is a waveform diagram of RSSI over a fixed distance. The blue curve is a waveform plot of 0 meters outside the vehicle, the green curve is a waveform plot of 1 meter outside the vehicle, the orange curve is a waveform plot of 2 meters outside the vehicle, and the red curve is a waveform plot of 3 meters outside the vehicle. As can be seen from the figure, the bluetooth signal itself has a fluctuation, and even if the fixed position is not changed, a jump occurs, and when the variation of the result exceeds the critical value of the area, the area variation is affected. And the RSSI values at different positions may partially overlap due to the characteristics of hopping themselves.

In the vehicle unlocking and locking scheme, the state may be determined inaccurately due to the influence of RSSI value jump and the like, for example, it is determined that the terminal frequently jumps between entering the unlocking/locking region and leaving the unlocking/locking region, which may cause the vehicle to repeatedly unlock after being locked.

Fig. 4 is a schematic diagram of a vehicle and an intelligent terminal under a vehicle control method according to an embodiment of the invention. Fig. 5 is a flowchart of a vehicle control method provided according to the present invention. As shown in fig. 5, the following steps are included.

In step S501, a distance between the vehicle and the smart terminal is calculated.

In step S502, the positional relationship between the intelligent terminal and the vehicle is determined based on the distance. When the position relation is that the intelligent terminal is located in the starting area defined by the fourth threshold, step S506 is executed, when the position relation is that the intelligent terminal is located in the unlocking/locking area defined by the second threshold, step S503 is executed, and when the position relation is that the intelligent terminal is located outside the unlocking/locking area defined by the first threshold, step S508 is executed.

In step S503, it is determined whether the position relationship is that the smart terminal enters the activation area defined by the third threshold or leaves the unlock/lock area defined by the second threshold, if the position relationship is that the smart terminal enters the activation area defined by the third threshold, step S504 is executed, and if the position relationship is that the smart terminal leaves the unlock/lock area defined by the second threshold, step S508 is executed.

In step S504, the vehicle is allowed to start or enter a standby power-on state without key, and the start area is expanded to an area defined by a fourth threshold.

In step S505, the vehicle is locked and the unlock/lock region is narrowed to a region defined by a first threshold.

In step S506, it is determined whether the smart terminal is leaving the activation area defined by the fourth threshold, and if the smart terminal is leaving the activation area defined by the fourth threshold, step S507 is executed.

In step S507, if the smart terminal leaves the activation area defined by the fourth threshold, the vehicle cannot be activated by keyless one-touch, and the activation area is reduced to the area defined by the third threshold.

In step S508, it is determined whether the position relationship is that the smart terminal enters the unlock/lock area defined by the first threshold, and if so, step S509 is performed.

In step S509, the vehicle is unlocked, and the unlock/lock area is expanded to an area defined by the second threshold.

The second threshold is larger than the first threshold, the fourth threshold is larger than the third threshold, and the first threshold is larger than the fourth threshold.

Firstly, after the intelligent terminal and the vehicle are connected for communication, the vehicle continuously calculates the distance between the intelligent terminal and the vehicle to determine the position relation between the intelligent terminal and the vehicle. The method comprises the steps that a user carrying the intelligent terminal is located outside an unlocking/locking area defined by PEin, when the intelligent terminal is detected to enter the unlocking/locking area defined by PEin, the vehicle is unlocked, the unlocking/locking area is expanded to an area defined by PEout, when the intelligent terminal is judged to leave the unlocking/locking area defined by PEout, the vehicle is automatically powered off and is locked, the unlocking/locking area is reduced to the area defined by PEin, and therefore when a follow-up vehicle judges that the intelligent terminal swings in the middle area between the PEin and the PEout, the intelligent terminal is always located in the unlocking/locking area, and the situation that the intelligent terminal is locked after being unlocked cannot occur repeatedly. Similarly, when the user carrying the intelligent terminal approaches the vehicle, when the intelligent terminal is judged to enter the starting area defined by the PSin, the vehicle can be started or enters the state to be powered on without a key, and the starting area is expanded to the area defined by the PSout.

In the above embodiments, the distance between the vehicle and the smart terminal may be theoretically calculated using a variety of different techniques, including but not limited to bluetooth signal strength (RSSI) ranging algorithm, infrared ranging algorithm, position sensor positioning and calculating distance, acoustic ranging, and the like.

Fig. 6 is a flow chart for calculating a distance based on RSSI according to an embodiment of the present invention. The method specifically comprises the following steps.

In step S601, sample data of n RSSI signals are read at regular intervals.

In step S602, the sample data is subjected to filter algorithm processing.

In step S603, the distance is calculated from the RSSI after the filtering process.

Various filtering algorithms may be adopted in the embodiment, for example, mean filtering is adopted, that is, an arithmetic mean of n RSSI is used as the filtered RSSI; filtering by adopting a Dixon detection method, namely arranging n RSSIs according to sizes, detecting whether the maximum value and the minimum value are outliers, removing the RSSI which is judged as the outliers, and taking the rest RSSIs as the filtered RSSIs; gaussian filtering can also be adopted, namely the RSSI value of a high probability occurrence area is selected, and the RSSI value of the interval is weighted and averaged to be used as the RSSI after filtering. When the RSSI after the filtering process is acquired, the distance is then calculated by using the formula (1). The bluetooth signal strength (RSSI) is a representation of the strength of the bluetooth signal between the transceiver devices, and is in positive correlation with the distance to some extent, so that the distance between the transceiver devices is deduced back through reasonable calculation and conversion and the RSSI value. See equation (1).

d＝10 ^{((abs(RSSI)-A)/(10*n))} Formula (1)

Wherein: d-the calculated distance, RSSI-received signal strength, signal strength when the A-transmitting end and the receiving end are separated by 1 meter, and n-environment attenuation factor. Due to different environments, the corresponding parameter values of each transmitting source (Bluetooth device) are different. Each parameter in the formula (1) should be obtained experimentally (calibration), and this is not described in detail here.

In an optional embodiment, m distance samples which are continuous in time are obtained according to the RSSI, an area where the intelligent terminal is located is judged according to the m distance samples, and whether the intelligent terminal is close to a vehicle or far from the vehicle is judged according to a variation trend of the m distance samples, so that whether the intelligent terminal enters an unlocking area or leaves an unlocking/locking area and whether the intelligent terminal enters a starting area or leaves the starting area is determined.

The above-described embodiment includes the case of enlarging and reducing the unlock/lock area and the case of enlarging and reducing the start area, but the purpose of these operations is to avoid the problem of frequent unlocking and locking and frequent starting and stopping of the vehicle in a specific scene, but leaving this specific scene, it is also necessary to restore the unlock/lock area and the start area at appropriate times. The terminal device may restore or set the unlock/lock area to the area defined by the first threshold and restore or set the activation area to the area defined by the third threshold before, while, or after the bluetooth connection is established with the vehicle through bluetooth. The unlock/lock area may also be restored or set to the area defined by the first threshold value and the activation area may also be restored or set to the area defined by the third threshold value when a certain condition is satisfied, for example, when it is determined that the smart terminal leaves the area defined by the fourth threshold value, the activation area is restored to the area defined by the third threshold value, and when it is determined that the smart terminal leaves the area defined by the second threshold value, the unlock/lock area is restored or set to the area defined by the first threshold value.

In addition, the present invention also provides a vehicle control method that sets an unlock region and a start region according to a bluetooth intensity signal and then is implemented in a similar idea to the embodiment of fig. 5. A detailed flowchart of the method is shown in fig. 7.

In step S701, the RSSI between the vehicle end and the smart terminal is acquired.

In step S702, the positional relationship between the smart terminal and the vehicle is determined based on the RSSI. When the position relationship is that the intelligent terminal is located in the start area defined by the fourth threshold, step S706 is executed, when the position relationship is that the intelligent terminal is located in the unlock/lock area defined by the second threshold, step S703 is executed, and when the position relationship is that the intelligent terminal is located outside the unlock/lock area defined by the first threshold, step S708 is executed.

In step S703, it is determined whether the position relationship is that the smart terminal enters the activation region defined by the third threshold or leaves the unlock/lock region defined by the second threshold, if the position relationship is that the smart terminal enters the activation region defined by the third threshold, step S704 is performed, and if the position relationship is that the smart terminal leaves the unlock/lock region defined by the second threshold, step S708 is performed.

In step S704, the vehicle is allowed to start or enter a standby power-on state without key-on, and the start area is expanded to an area defined by a fourth threshold.

In step S705, the vehicle is locked and the unlock/lock area is narrowed to an area defined by a first threshold.

In step S706, it is determined whether the smart terminal is leaving the activation area defined by the fourth threshold, and if it is leaving the activation area defined by the fourth threshold, step S707 is executed.

In step S707, if the smart terminal leaves the activation region defined by the fourth threshold, the vehicle cannot be activated by one key without a key, and the activation region is reduced to a region defined by the third threshold.

In step S708, it is determined whether the position relationship is that the smart terminal enters the unlock/lock area defined by the first threshold, and if so, step S709 is executed.

In step S709, the vehicle is unlocked, and the unlock/lock area is expanded to an area defined by the second threshold.

The second threshold is larger than the first threshold, the fourth threshold is larger than the third threshold, and the first threshold is larger than the fourth threshold.

For example. For example, if the unlock region is defined as 3 meters outside the vehicle, the RSSI is 70dBm, the start region is defined as 1 meter, and the RSSI is 90dBm, the first threshold value is 70dBm, and the third threshold value is 90dBm, corresponding to this embodiment. In the process that a user carrying the intelligent terminal approaches a vehicle, the current RSSI value is continuously calculated, for example, N RSSI values can be continuously collected and averaged to be used as the current RSSI. When the RSSI is determined to be greater than 70dBm and the smart terminal approaches the vehicle, it may be determined that the smart terminal enters the unlock zone, thus unlocking the vehicle and expanding the unlock zone to a zone defined by, for example, 60dBm (the distance is inversely proportional to the RSSI), and when the RSSI is determined to be less than 70dBm and the smart terminal is away from the vehicle, it may be determined that the smart terminal leaves the unlock zone, thus locking the vehicle and reducing the unlock zone to a zone defined by, for example, 80dBm (the distance is inversely proportional to the RSSI). Therefore, the situation that the vehicle is locked after being unlocked can not occur repeatedly. Similarly, when the user carrying the intelligent terminal approaches the vehicle, when the RSSI is determined to be greater than 90dBm, the intelligent terminal can be determined to enter the start area, so that the vehicle can be started by one key or enter a standby power-on state, the start area is expanded to an area defined by 80dBm, when the RSSI is determined to be less than 90dBm and the intelligent terminal is far away from the vehicle, namely the intelligent terminal is determined to leave the start area, the vehicle cannot be started by one key, and the start area is reduced to an area defined by 100 dBm.

In an optional embodiment, m RSSI samples which are continuous in time are obtained, the area where the intelligent terminal is located is judged according to the m RSSI samples, and whether the intelligent terminal is gradually close to the vehicle or gradually far away from the vehicle is judged according to the variation trend of the m RSSI samples, so that whether a user carrying the intelligent terminal enters the unlocking/locking area or leaves the unlocking/locking area, and whether the user enters the starting area or leaves the starting area is determined.

It should be noted that although the above embodiments are described with respect to unlocking and locking between a vehicle and a smart terminal, the embodiments are not limited to vehicles and smart terminals, but may also be applied to other similar intelligent unlocking and locking systems, such as unlocking and locking a smart door by a smart key (generally referred to as an access system), and unlocking and locking a smart safe by a smart terminal.

It should also be noted that, in the above embodiment, the distance is calculated and the position relationship is determined by the intelligent terminal, when the unlocking (or locking) condition or the starting (or flameout) condition is met, a corresponding command is sent to the vehicle, and the vehicle executes a corresponding operation after receiving the corresponding command; however, in practice, it is also possible that the vehicle or the in-vehicle terminal calculates the distance and determines the positional relationship, and when the unlock (or lock) condition or the start (or key-off) condition is satisfied, the corresponding operation is performed.
