The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A vehicle unlocking system and method of an embodiment of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a block schematic diagram of a vehicle unlocking system according to an embodiment of the present invention.
As shown in fig. 1, a vehicle unlocking system of an embodiment of the present invention may include: a virtual key 10 and a key controller 20.
Wherein the virtual key 10 and the key controller 20 perform information interaction. The virtual key 10 is used to transmit a control signal of a user, wherein the virtual key 10 transmits the control signal through a mobile device. The key controller 20 is configured to obtain a signal strength of a control signal sent by the virtual key, determine a location area of the mobile device according to the signal strength, obtain a running direction of the mobile device relative to the vehicle body, and control the vehicle according to the location area and the running direction of the mobile device.
Specifically, the key controller 20 interacts with the virtual key 10 through BLE (Bluetooth Low Energy) Bluetooth communication, and the interaction mainly includes: identification, door unlocking command of the virtual key, window lifting command, car lamp control command, key position information and the like. The key controller 20 is connected to a Controller Area Network (CAN) Network of the entire vehicle, and together with a Passive Entry Passive Start (PEPS) and a Body Control Module (BCM) complete functions of keyless Entry, keyless Start, welcome lamp Control, vehicle information display, and the like of the vehicle.
The driver may send a control signal through an APP (Application) on the mobile device (e.g., a mobile phone, a tablet computer, etc.), wherein the virtual key may be an APP on the mobile device, and the virtual key 10 may send the control signal to the key controller 20 through a bluetooth communication technology. The key controller 20 determines the area where the mobile device is located (i.e. the current position of the driver) according to the signal strength of the control signal, and then acquires the running direction of the mobile device relative to the vehicle body, i.e. determines whether the driver is gradually approaching the vehicle or is far away from the vehicle, so that the key controller 20 controls the vehicle according to the area where the mobile device is located and the running direction. For example, when the driver is in the welcome area and gradually approaches the vehicle, the key controller 20 controls the lamps to be turned on; when the driver is in the lock area and is gradually away from the vehicle, the key controller 20 controls the doors to be automatically closed.
According to an embodiment of the present invention, the key controller 20 is specifically configured to obtain a distance between the vehicle body and the mobile device, and determine a current location area of the mobile device according to the distance between the vehicle body and the mobile device; and tracking the distance between the vehicle body and the mobile equipment in real time so as to obtain the running direction of the mobile equipment relative to the vehicle according to the change rule of the distance between the vehicle body and the mobile equipment.
According to one embodiment of the invention, the region comprises: the first region, the second region, the third region, and the fourth region are gradually decreased in distance from the vehicle body from the first region to the fourth region.
According to an embodiment of the present invention, the key controller 20 is further configured to compare a distance between the mobile device and the vehicle body with a preset interval, determine a target interval where the mobile device is located, and determine a target area where the mobile device is located according to the target interval; wherein the target area is one of the first area to the fourth area.
If the distance between the mobile equipment and the vehicle is smaller than or equal to a first preset value and larger than a second preset value, the mobile equipment belongs to a first area; when the distance between the mobile equipment and the vehicle is smaller than or equal to a second preset value and larger than a third preset value, the mobile equipment belongs to a second area; when the distance between the mobile equipment and the vehicle is smaller than or equal to a third preset value and larger than a fourth preset value, the mobile equipment belongs to a third area; and when the distance between the mobile equipment and the vehicle is smaller than or equal to a fourth preset value, the mobile equipment is in a fourth area. The first preset value, the second preset value, the third preset value and the fourth preset value can be calibrated according to actual conditions.
Specifically, as shown in fig. 2, the first region may be a welcome region, the distance from the vehicle body is generally 4-5m, the second region may be a lock region, the distance from the vehicle body is generally 2-3m, the third region may be an unlock region, the distance from the vehicle body is generally 1m, and the fourth region may be a start region. The distance between the mobile device and the vehicle body may be obtained according to the signal strength of the mobile device, for example, the distance between the mobile device and the vehicle body may be obtained based on the RSSI positioning. And judging whether the driver is close to the vehicle or far from the vehicle according to the position change between the mobile device and the vehicle body, wherein when the distance between the mobile device and the vehicle body is gradually reduced, the driver is close to the vehicle, and when the distance between the mobile device and the vehicle body is gradually increased, the driver is far from the vehicle, so that the running direction of the mobile device relative to the vehicle can be determined.
According to an embodiment of the present invention, when the mobile device enters the fourth area and the moving direction of the mobile device is close to the vehicle, the key controller 20 is further configured to: sending an adjusting instruction to the mobile equipment so that the mobile equipment can adjust the signal intensity of the sent control signal; and detecting the adjusted signal intensity, and if the signal intensity is smaller than a preset threshold value, determining that the mobile equipment enters the vehicle.
According to one embodiment of the present invention, upon determining that the mobile device enters the vehicle, the key controller 20 starts the vehicle.
Specifically, when the mobile device enters the fourth area from the third area (enters the start area from the unlock area), after the vehicle is powered on, the key controller 20 sends a signal intensity instruction for reducing a control signal sent by the mobile device, so that the start area is a low field intensity area, the adjusted signal intensity is detected, when the signal intensity is smaller than a preset threshold value, it is determined that the mobile device enters the vehicle, and at this time, it indicates that the driver is in the vehicle, and the vehicle is controlled to start.
According to an embodiment of the present invention, the key controller 20 controls the vehicle according to the area of the mobile device, and is specifically configured to control the lights of the vehicle to be in an on state when the mobile device is in the first area and the operation direction is close to the vehicle body; when the mobile equipment is in the second area and the running direction is far away from the vehicle body, controlling the vehicle door of the vehicle to be automatically closed; and when the mobile equipment is in the third area and the running direction is close to the vehicle body, controlling the vehicle door to be automatically opened.
That is, when the driver walks close to the vehicle and enters a first area (welcome area), the welcome lamp on the vehicle is controlled to be automatically turned on; when a driver walks close to the vehicle and enters a third area (an unlocking area), controlling the door of the vehicle to be automatically opened; when the driver walks away from the vehicle and enters the second area from the third area, the door of the vehicle is controlled to be automatically closed, and therefore user experience is improved.
According to another embodiment of the present invention, the key controller 20 may include: the key controller 20 obtains the signal strength of the control signal through the master node to obtain the distance between the key controller and the mobile device, and determines the current location area of the mobile device according to the distance between the key controller and the mobile device; the key controller 20 calculates the position information of the mobile device through a three-terminal positioning algorithm according to the position information of the master node, the position information of the slave node and the distance between the key controller and the mobile device; the key controller 20 tracks the position information of the mobile device to obtain the traveling direction of the mobile device relative to the vehicle according to the change rule of the position information of the mobile device.
Specifically, as shown in fig. 3, the key controller 20 obtains the signal strength of the virtual key through the master node, and performs calculation and positioning, and since the bluetooth wireless signal is propagated in the air, the length of the bluetooth signal decreases with the increase of the transmission distance, and the attenuation value is RSSI (d) ═ a-10nlg (d), where RSSI represents the signal strength received by the receiving end when the distance from the transmitter is d, n is a path Loss (Pass Loss) index, and a is the wireless signal strength RSSI value received by the receiving node when the distance from the wireless transceiver node is 1 m. The distance value between the key controller and the mobile device can be obtained through the formula. Then, the centroid location algorithm calculates the centroid location coordinate, i.e. the location of the mobile device, by using the centroid formula, with the coordinates of the three beacon points, i.e. the master node and the two slave nodes, being known and a certain distance difference being generated at the same time.
Because the method has certain errors, the method of collecting RSSI values for multiple times within a certain time and simultaneously performing a mean value algorithm is adopted, so that the accuracy of distance calculation is improved. It can be understood that the controller can adapt adaptively on the calibration algorithm due to the different attenuation rates of the Andriod smart device and the IOS mobile device. By the method, the position (inside and outside the vehicle) of the mobile equipment can be effectively distinguished.
It should be noted that, in the above formula, n is a path Loss (Pass Loss) index, which is generally obtained by actual measurement, and the more obstacles, the larger n is, so that the speed of the drop of the received average energy becomes faster and faster with the increase of the distance; a and n are empirical values and are closely related to the specifically used hardware nodes and the wireless signal propagation environment, so that the A and n parameters are different under different actual environments, and the ranging models are different.
In addition, the master node is responsible for communicating with the mobile device, the distance range between the master node and the outside of the vehicle is judged through the Bluetooth field intensity, an unlocking area, a locking area and a welcoming area are determined, the safety certification work is completed, and the slave node is responsible for completing connection with a virtual key, identity certification and receiving of a control command.
When the mobile equipment is in a starting area (a low field intensity mode, when the mobile equipment enters the starting area, the slave node is adjusted to enable the mobile equipment to be in the low field intensity mode at present), the slave node judges whether the mobile equipment is in a vehicle, and when the mobile equipment is in other areas (a high field intensity mode), the master node and the slave node judge whether the mobile equipment is in the vehicle in a three-terminal positioning mode.
In conclusion, the hardware encryption authentication communication level between the key controller and the mobile device (mobile phone, watch) and the PEPS at the vehicle end reaches the financial security level, and the privacy protection and the theft prevention of the vehicle information and the vehicle control are ensured.
In addition, the vehicle unlocking system can realize the following functions: the system comprises functions of user login, virtual key input, virtual key system Bluetooth connection, virtual key system disconnection Bluetooth connection, user authorized vehicle borrowing, APP user setting, virtual key intelligent entry function, welcome early lighting function, virtual key remote control unlocking function, virtual key remote control locking function, virtual key remote control trunk opening function, virtual key remote control vehicle finding function, virtual key starting, vehicle window remote control ascending, vehicle window remote control descending, skylight remote control, vehicle information display and the like.
In summary, according to the vehicle unlocking system in the embodiment of the present invention, the virtual key sends the control signal of the user through the mobile device, and the key controller obtains the signal intensity of the control signal sent by the virtual key, determines the area where the mobile device is located according to the signal intensity, obtains the running direction of the mobile device relative to the vehicle body, and controls the vehicle according to the area where the mobile device is located and the running direction. Therefore, the system communicates with the mobile equipment carried by the user through the key controller at the vehicle end to interact vehicle information, issue a control instruction, and meanwhile, realize the positioning inside and outside the vehicle of the mobile equipment, so that the judgment that the driver can start the vehicle when the driver is inside the vehicle can be realized.
