Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The carrier unlocking method provided by the embodiment can be applied to a carrier. The vehicle is provided with an ECU module (Electronic Control Unit, abbreviated as ECU, electronic control unit), and a first communication terminal and a second communication terminal connected to the ECU module. The first communication terminal and the second communication terminal may be bluetooth modules or communication modules having a medium-to-long range communication function (e.g., 5m to 300 m). Here, the vehicle may be a vehicle that the car obtains other vehicles that need to be unlocked.
In an embodiment, as shown in fig. 1, a method for unlocking a carrier is provided, which includes the following steps S10-S50.
S10, acquiring a first communication signal of the unlocking terminal.
An unlock terminal is understood to mean a terminal with an unlock carrier function. Unlocking terminals include, but are not limited to, smart car keys, smart phones, smart watches. Here, the unlocking terminal may establish a first communication connection with a first communication terminal of the carrier. The unlocking terminal may transmit the first communication signal to the first communication terminal. In an example, the first communication signal may be a bluetooth signal. The radius of the first signal coverage of the first communication terminal may be 80m-300m.
S20, determining the physical distance between the unlocking terminal and the carrier according to the strength of the first communication signal.
As can be appreciated, the first communication terminal, after receiving the first communication signal transmitted by the unlocking terminal, may calculate the physical distance between the unlocking terminal and the carrier according to the signal strength (RSSI, received Signal Strength Indication) of the first communication signal. In general, the farther the distance, the smaller the signal strength (absolute value); the closer the distance, the greater the signal strength (absolute value).
S30, when the physical distance is smaller than a preset distance threshold, sending out a second communication signal.
It is understood that the preset distance threshold may be set according to actual needs, for example, may be 10m-30m. When the physical distance between the unlocking terminal and the carrier is smaller than a preset distance threshold, a second communication signal can be sent out by the second communication terminal. In an example, the radius of the second signal coverage of the second communication terminal may be 5m. Here, the second communication terminal transmits only the second communication signal and does not receive the communication signal in a wireless manner.
When the physical distance is greater than or equal to the preset distance threshold, the second communication terminal does not send out a second communication signal.
S40, receiving an unlocking signal which is sent by the unlocking terminal and responds to the second communication signal.
Understandably, when the distance between the unlocking terminal and the carrier is smaller than the radius of the second signal coverage of the second communication terminal, the unlocking terminal detects the second communication signal and triggers the unlocking instruction. Executing the unlocking instruction, the unlocking terminal may send an unlocking signal to the first communication terminal. Here, the unlocking signal may be used to unlock a door of the vehicle, such as a vehicle door.
S50, unlocking the carrier according to the unlocking signal.
It is understood that after the first communication terminal receives the unlocking signal, the unlocking signal may be transmitted to the ECU module, and then the ECU module unlocks the vehicle.
In step S10-S50, a first communication signal of the unlocking terminal is obtained, so as to determine a physical distance between the unlocking terminal and the carrier according to the intensity of the first communication signal. And determining the physical distance between the unlocking terminal and the carrier according to the strength of the first communication signal so as to judge whether to send out the second communication signal or not through the physical distance between the unlocking terminal and the carrier. And when the physical distance is smaller than a preset distance threshold, sending out a second communication signal so that the second communication signal can be detected when the unlocking terminal approaches to the carrier. And receiving an unlocking signal which is sent by the unlocking terminal and responds to the second communication signal, wherein when the unlocking terminal detects the second communication signal, the distance between the unlocking terminal and the carrier is close enough, and the unlocking terminal can request unlocking to the carrier at the moment. And unlocking the carrier according to the unlocking signal to finish the operation of unlocking the carrier. According to the embodiment, through monitoring of two different communication signals, the carrier can be prevented from being attacked by broadcast relay, the risk of the carrier being stolen is reduced, and the safety of a carrier unlocking system is further improved.
Optionally, before step S40, that is, before receiving the unlocking signal sent by the unlocking terminal and responding to the second communication signal, the method includes:
s41, acquiring a displacement state of the unlocking terminal after the unlocking terminal detects the second communication signal;
and S42, if the displacement state is a motion state, the unlocking terminal sends the unlocking signal to the carrier.
Understandably, the unlocking terminal may detect the second communication signal when the distance of the unlocking terminal from the carrier is smaller than the radius of the second signal coverage of the second communication terminal. Then, the unlocking terminal acquires the displacement state of the unlocking terminal. Here, the displacement state includes two kinds, one is a stationary state and the other is a moving state. The displacement state can be judged through the sensing data collected by the unlocking terminal. In some examples, the unlock terminal may collect the above-described sensed data via a displacement sensor.
And when the displacement state is a motion state, the unlocking terminal sends an unlocking signal to the carrier. When the displacement state is a static state, the unlocking terminal does not send an unlocking signal.
And detecting the displacement state of the unlocking terminal, and if the displacement state is a motion state, sending the unlocking signal to the carrier by the unlocking terminal. The method can avoid sending out signals in the static state of the unlocking terminal, and reduces the risk of relay attack.
Optionally, before step S10, that is, before the acquiring the first communication signal of the unlock terminal, the method further includes:
s12, receiving a connection request of the unlocking terminal;
s13, authenticating the connection request;
and S14, if the connection request passes the authentication, establishing a first communication connection between the carrier and the unlocking terminal.
Understandably, the ECU module needs to authenticate the identity of the unlock terminal before the first communication connection is established. Specifically, the connection request of the unlocking terminal may be received through the first communication terminal. The connection request may contain authentication information to unlock the terminal. The ECU module may authenticate the connection request of the unlocking terminal. If the authentication is passed, a first communication connection between the carrier and the unlock terminal (first communication terminal) can be established. Here, the first communication connection may enable a bi-directional data transfer, i.e. the unlocking terminal may send data to the first communication terminal, which may also send data to the unlocking terminal.
Optionally, before step S12, that is, before the receiving the connection request of the unlocking terminal, the method further includes:
and S11, when the unlocking terminal is in the first signal coverage range of the first communication terminal of the carrier, the unlocking terminal sends the connection request to the first communication terminal, and the first communication terminal is arranged on the carrier.
The first communication terminal may be a bluetooth module. The first signal coverage area may be a circular area with a radius of 80m-300m. The first signal coverage relates to the signal processing capabilities of the first communication terminal (including the transmitting signal capabilities and the receiving signal capabilities), to the signal processing capabilities of the unlocking terminal, and to the building structure of the field environment.
When the unlocking terminal is in the first signal coverage range of the first communication terminal and the signal transmitted by the first communication terminal is monitored, the unlocking terminal sends a connection request to the first communication terminal.
Optionally, step S30, that is, when the physical distance is smaller than the preset distance threshold, sends out a second communication signal, includes:
s301, when the physical distance is smaller than a preset distance threshold, sending an activation instruction to a second communication terminal of the carrier, so that the second communication terminal enters a working state through the activation instruction;
s302, sending out the second communication signal through the second communication terminal.
The second communication terminal may be a bluetooth module, as will be appreciated. The second communication signal may be a bluetooth signal. When the physical distance is smaller than the preset distance threshold, the ECU can send an activation instruction to the second communication terminal, and the second communication terminal is activated through the activation instruction, so that the second communication terminal enters a working state.
After the second communication terminal enters the working state, a second communication signal is sent out according to a certain frequency. Therefore, the second communication terminal enters the working state only when the unlocking terminal is close, and the energy consumption of the second communication terminal can be greatly saved.
And after the second communication terminal is activated by the activation instruction, carrying out communication operation, and if the second communication terminal is not activated, the second communication terminal is in a standby state, so that the second communication terminal can be prevented from being directly attacked, and the carrier is unlocked.
It should be noted that, here, the second communication terminal only transmits the second communication signal, and does not receive the communication signal in a wireless manner.
Optionally, the first communication signal is received through a first communication terminal of the carrier; sending out the second communication signal through a second communication terminal of the carrier;
the radius of the first signal coverage of the first communication terminal is larger than the radius of the second signal coverage of the second communication terminal.
It is understood that two different communication terminals, a first communication terminal and a second communication terminal, respectively, may be used. The radius of the first signal coverage of the first communication terminal is typically 80m to 300m. The radius of the second signal coverage of the second communication terminal is typically around 5m. Thus, the radius of the first signal coverage of the first communication terminal is smaller than the radius of the second signal coverage of the second communication terminal.
Optionally, step S50, after unlocking the carrier according to the unlocking signal, further includes:
and S60, sending a standby instruction to a second communication terminal of the carrier so as to enable the second communication terminal to enter a standby state through the standby instruction, wherein the second communication terminal is used for sending out the second communication signal.
It is understood that after unlocking the carrier, the second communication terminal may be turned off, and put in a standby state, so as to reduce the power consumption of the second communication terminal.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
In an embodiment, as shown in fig. 2, a method for unlocking a carrier is provided, which includes the following steps S100-S200.
S100, a first communication signal is sent to a first communication terminal of a carrier, so that the carrier determines the physical distance between an unlocking terminal and the carrier according to the strength of the first communication signal;
s200, when a second communication signal is detected, an unlocking signal is sent to the first communication terminal so as to unlock the carrier through the unlocking signal; the second communication signal is a communication signal sent by the second communication terminal of the carrier when the physical distance is smaller than a preset distance threshold.
Understandably, the carrier unlocking method provided in the embodiment is applied to an unlocking terminal. Here, the unlocking terminal may be a smart phone, a smart watch, a smart car key, or the like.
