Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. 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 control system, a method, and a vehicle of an electronic lock of an embodiment of the invention are described below with reference to the drawings.
It should be noted that, considering that there may be a need for manual unlocking in an actual charging process of a user, if the controller continuously drives the electronic lock at the forward level, when the user needs to manually unlock, because the controller continuously outputs the forward level drive, a situation that the controller directly drives to lock just after the user completes manual unlocking occurs, which seriously affects user experience.
In addition, according to the control strategy of the electronic lock in the prior art, the controller only applies pulses to the electronic lock when executing the BMS command to drive the electronic lock to be locked or unlocked, and in other cases, if there is a manual unlocking demand in the charging process, the entire vehicle controller may not detect the real state of the electronic lock due to the fact that the driving of the electronic lock does not supply power, which is not beneficial to the realization of the entire vehicle anti-theft function.
Therefore, the embodiment of the invention provides a control system 100 of an electronic lock, which can realize real-time monitoring of the state of the electronic lock, accurately feed back the state of the electronic lock and perfect the anti-theft function of the whole vehicle.
Fig. 1 is a block diagram illustrating a control system of an electronic lock according to an embodiment of the present invention.
As shown in fig. 1, a control system 100 of an electronic lock includes: electronic lock 1, controller 2 and detecting element 3.
The controller 2 is configured to input a first forward driving pulse voltage signal with a pulse width of a first time to the electronic lock 1 after receiving an electronic lock locking instruction, so as to control the electronic lock 1 to automatically lock, and input a second forward driving pulse voltage signal with a pulse width of a third time to the electronic lock 1 every second time after the electronic lock 1 is automatically locked; the detection unit 3 is configured to determine whether the electronic lock 1 is manually unlocked after the electronic lock 1 is automatically locked according to whether the state voltage signal output by the electronic lock 1 is detected.
It should be noted that the second time is longer than the first time, and the first time is longer than the third time.
Optionally, the first time may have a value in a range of 450 ms to 550 ms, the second time may have a value in a range of 900 ms to 1100 ms, and the third time may have a value in a range of 15 ms to 25 ms, for example, in an embodiment of the present invention, the first time may be preferably 500 ms, the second time may be preferably 1000 ms (1 second), and the third time may be preferably 20 ms.
For example, after the controller 2 receives the electronic lock locking instruction, a first forward driving pulse voltage signal with a pulse width of 500 milliseconds is input to the electronic lock 1 to control the electronic lock 1 to be automatically locked, and after the electronic lock 1 is automatically locked, a second forward driving pulse voltage signal with a pulse width of 20 milliseconds is input to the electronic lock 1 every 1000 milliseconds, that is, the controller 2 periodically sends a short pulse to the electronic lock 1, and further, the detection unit 3 determines whether the electronic lock 1 is manually unlocked after the electronic lock 1 is automatically locked according to whether the state voltage signal output by the electronic lock 1 is detected.
It should be understood that, since the pulse width (the third time) of the second forward driving pulse voltage signal is smaller than the pulse width (the first time) of the first forward driving pulse voltage signal, the electronic lock 1 is not locked, and meanwhile, a corresponding driving pulse can be provided for the state monitoring of the electronic lock 1, so that the real-time monitoring of the state of the electronic lock 1 is realized, and the state of the electronic lock 1 is accurately fed back.
Further, in the embodiment of the present invention, the controller 2 is further configured to: after receiving an unlocking instruction of the electronic lock, inputting a negative driving pulse voltage signal with the pulse width of the first time to the electronic lock 1 so as to control the electronic lock 1 to automatically unlock.
That is, after the controller 2 receives an unlocking instruction of the electronic lock, a negative driving pulse voltage signal with a pulse width of a first time is input to the electronic lock 1 to control the electronic lock 1 to automatically unlock.
Alternatively, after the electronic lock 1 completes the automatic unlocking, a second forward driving pulse voltage signal with a pulse width of 20 milliseconds may be input to the electronic lock 1 every 1000 milliseconds, that is, the controller 2 periodically sends a short pulse to the electronic lock 1, and then, the detecting unit 3 determines whether the electronic lock 1 is manually locked after the electronic lock 1 completes the automatic unlocking according to whether the state voltage signal output by the electronic lock 1 is detected.
Further, in the embodiment of the present invention, the detecting unit 3 is specifically configured to: detecting a state voltage signal output by the electronic lock 1, and judging that the electronic lock 1 is manually unlocked after the electronic lock 1 is automatically locked; if the state voltage signal output by the electronic lock 1 is not detected, it is determined that the electronic lock 1 is not manually unlocked after the electronic lock 1 is automatically locked.
Specifically, in the embodiment of the present invention, when the detection unit 3 detects the state voltage signal output by the electronic lock 1, it may be considered that the electronic lock 1 is manually unlocked after the electronic lock 1 is automatically locked, and when the detection unit 3 does not detect the state voltage signal output by the electronic lock 1, it may be considered that the electronic lock 1 is not manually unlocked after the electronic lock 1 is automatically locked, so that, if there is a manual unlocking requirement during the charging process, the situation that the vehicle controller cannot detect the real state of the electronic lock due to the fact that the power is not supplied to the electronic lock is avoided, and the vehicle anti-theft function is improved.
The structure of the electronic lock 1 and the detecting unit 3 will be described with reference to fig. 2 and the embodiment of the present invention.
Specifically, in the embodiment of the present invention, as shown in fig. 2, the electronic lock 1 includes: an input positive terminal 11, an input negative terminal 12, a first switch 13, a first diode 14, a motor 15, a second diode 16, a third diode 17, a second switch 18, a fourth diode 19, a fifth diode 20, and a sixth diode 21.
Wherein, the first end of the first switch 13 is connected with the input positive end 11; the cathode of the first diode 14 is connected to the positive input terminal 11; a first terminal of the motor 15 is connected to an anode of the first diode 14; the cathode of the second diode 16 is connected with the first end of the motor 15, and the anode of the second diode 16 is connected with the second end of the first switch 13; the anode of the third diode 17 is connected with the second end of the motor 15, and the cathode of the third diode 17 is connected with the input negative end 12; a first end of the second switch 18 is connected with the input negative terminal 12; the cathode of the fourth diode 19 is connected to the second end of the motor 15, and the anode of the fourth diode 19 is connected to the second end of the second switch 18; the anode of the fifth diode 20 is connected to the second end of the first switch 13, and the cathode of the fifth diode 20 is connected to the detection unit 3; an anode of the sixth diode 21 is connected to the second terminal of the second switch 18, and a cathode of the sixth diode 21 is connected to the detection unit 3.
Specifically, after the controller 2 receives the electronic lock locking instruction, and outputs a first forward driving pulse voltage signal with a pulse width of 500 milliseconds through the input positive terminal 11, since the first switch 13 is in a normally closed state, the first diode 14, the second diode 16 and the fifth diode 20 are turned on, and the electronic lock 1 is automatically locked, at this time, the detection unit 3 is connected to the electronic lock 1 through the sixth diode 20 to detect the state of the electronic lock 1.
And after the electronic lock 1 finishes the automatic locking, the first switch 13 is changed from the normally closed state to the normally open state, at this time, if the user carries out the manual unlocking operation, the first switch 13 is changed from the normally open state to the normally closed state again, therefore, a second forward driving pulse voltage signal with the pulse width of 20 milliseconds is input to the electronic lock 1 every 1000 milliseconds through the controller 2, and further, whether the electronic lock 1 is manually unlocked after the electronic lock 1 finishes the automatic locking is judged through the detection unit 3 according to whether the state voltage signal output by the electronic lock 1 is detected.
Similarly, when the controller 2 receives an unlocking instruction of the electronic lock and outputs a first forward driving pulse voltage signal with a pulse width of 500 milliseconds through the input negative terminal 12, the electronic lock 1 is automatically unlocked because the second switch 18 is in a normally closed state and the third diode 17, the fourth diode 19 and the sixth diode 21 are conducted, and at this time, the detection unit 3 is connected to the electronic lock 1 through the sixth diode 21 to detect the state of the electronic lock 1.
And after the electronic lock 1 finishes the automatic unlocking, the second switch 18 is changed from the normally closed state to the normally open state, at this time, if a user carries out the manual unlocking operation, the second switch 18 is changed from the normally open state to the normally closed state again, therefore, a second forward driving pulse voltage signal with the pulse width of 20 milliseconds is input to the electronic lock 1 every 1000 milliseconds through the controller 2, and further, whether the electronic lock 1 is manually locked after the electronic lock 1 finishes the automatic unlocking is judged through the detection unit 3 according to whether the state voltage signal output by the electronic lock 1 is detected.
It should be understood that, when the electronic lock 1 is automatically locked, the first switch 13 is turned from the normally closed state to the normally open state, and the second switch 18 is in the inactive state (i.e. in the normally open state), and, when the electronic lock 1 is automatically unlocked, the second switch 18 is turned from the normally closed state to the normally open state, and the first switch 13 is in the inactive state (i.e. in the normally open state).
Further, in the embodiment of the present invention, as shown in fig. 2, the detection unit 3 includes: a pull-down resistor 31 and a detection circuit 32.
A first end of the pull-down resistor 31 is connected with the electronic lock 1, and a second end of the pull-down resistor 31 is grounded; the detection circuit 32 is connected to a first terminal of the pull-down resistor 31.
That is, the detection unit 3 may determine whether the electronic lock 1 is manually unlocked or locked after the electronic lock 1 is automatically locked or unlocked by the detection circuit 32 according to whether the state voltage signal output by the electronic lock 1 on the pull-down resistor 31 is detected.
Specifically, in order to realize real-time monitoring of the state of the electronic lock 1 of the whole vehicle, the embodiment of the invention provides a method for monitoring the state of the electronic lock 1 in real time by periodically sending short pulses through the controller 2. Taking the control strategy of the electronic lock 1 for locking as an example, when the electronic lock 1 is normally locked, the controller 2 outputs a first forward driving pulse voltage signal with a pulse width of 500 milliseconds to control the electronic lock 1 to be automatically locked, and after the electronic lock 1 is automatically locked, the controller 2 sends a second forward driving pulse voltage signal with a pulse width of 20 milliseconds to the electronic lock 1 every 1000 milliseconds, so as to realize real-time monitoring of the state of the electronic lock. At this time, if the manual unlocking by the user is completed, the state of the first switch 13 is normally closed, and the controller 2 sends a second forward driving pulse voltage signal with a pulse width of 20 milliseconds, the control unit 4 may detect the voltage through the detection circuit 32, and may know that the electronic lock 1 has performed the manual unlocking operation, and at the same time, the second forward driving pulse voltage signal with a pulse width of 20 milliseconds may not cause the locking of the electronic lock 1, that is, the electronic lock 1 according to the embodiment of the present invention may detect the user behavior of reporting the manual unlocking in real time, and at the same time, the user may perform the gun pulling (charging) operation.
Furthermore, it should be understood that, in the case where the electronic lock 1 is not manually unlocked, the state of the first switch 13 is normally open, and the controller 2 does not form a closed loop for the driving circuit of the electronic lock 1, and the power consumption of the controller 2 is not increased.
That is to say, the control system of the electronic lock of the embodiment of the invention can realize real-time monitoring of the state of the electronic lock 1 at the charging port of the whole vehicle, accurately feed back the state of the electronic lock 1, better serve the anti-theft function of the whole vehicle, improve the user experience, and simultaneously, cannot increase the additional power consumption of the controller 2 or the whole vehicle.
In addition, the control strategy for unlocking the electronic lock 1 is opposite to the control strategy, and is not described herein again.
In summary, according to the control system of the electronic lock of the embodiment of the invention, after the controller receives the electronic lock locking instruction, the controller inputs a first forward driving pulse voltage signal with a pulse width of a first time to the electronic lock to control the electronic lock to be automatically locked, and after the electronic lock is automatically locked, the controller inputs a second forward driving pulse voltage signal with a pulse width of a third time to the electronic lock at intervals of a second time, and the detection unit determines whether the electronic lock is manually unlocked after the electronic lock is automatically locked according to whether the detection unit detects the status voltage signal output by the electronic lock. Therefore, after the electronic lock is automatically locked, the state of the electronic lock is monitored in real time, the state of the electronic lock is accurately fed back, and the anti-theft function of the whole vehicle is perfected in a mode that the controller periodically sends a second forward driving pulse voltage signal.
Fig. 3 is a flowchart illustrating a control method of an electronic lock according to an embodiment of the invention.
As shown in the figure, the control method of the electronic lock comprises the following steps:
s101, after receiving an electronic lock locking instruction, inputting a first forward driving pulse voltage signal with a pulse width of a first time to the electronic lock to control the electronic lock to be automatically locked, and after the electronic lock is automatically locked, inputting a second forward driving pulse voltage signal with a pulse width of a third time to the electronic lock at intervals of a second time.
That is, after receiving the locking instruction of the electronic lock, a first forward driving pulse voltage signal with a pulse width of a first time is input into the electronic lock to control the electronic lock to be automatically locked, and after the electronic lock is automatically locked, a second forward driving pulse voltage signal with a pulse width of a third time is input into the electronic lock every second time, wherein the second time is longer than the first time, and the first time is longer than the third time.
And S102, judging whether the electronic lock is manually unlocked after the electronic lock is automatically locked according to whether the state voltage signal output by the electronic lock is detected.
After a second forward driving pulse voltage signal with a pulse width of a third time is input to the electronic lock every second time, whether the electronic lock is manually unlocked after the electronic lock is automatically locked is judged according to whether a state voltage signal output by the electronic lock is detected.
Further, in an embodiment of the present invention, as shown in fig. 4, the method for controlling an electronic lock further includes:
and S103, after receiving an unlocking instruction of the electronic lock, inputting a negative driving pulse voltage signal with the pulse width of the first time to the electronic lock so as to control the electronic lock to automatically unlock.
That is, after receiving an unlocking instruction of the electronic lock, a negative driving pulse voltage signal with a pulse width of a first time is input into the electronic lock to control the electronic lock to automatically unlock.
Further, in an embodiment of the present invention, as shown in fig. 5, the method for controlling an electronic lock further includes:
s201, detecting a state voltage signal output by the electronic lock, and judging that the electronic lock is manually unlocked after the electronic lock is automatically locked.
That is, when the state voltage signal output by the electronic lock is detected, it is determined that the electronic lock is manually unlocked after the electronic lock is automatically locked.
S202, if the state voltage signal output by the electronic lock is not detected, it is judged that the electronic lock is not manually unlocked after the electronic lock is automatically locked.
That is, when the state voltage signal output by the electronic lock is not detected, it is determined that the electronic lock is not manually unlocked after the electronic lock is automatically locked.
It should be noted that the control method of the electronic lock according to the embodiment of the present invention corresponds to the specific implementation of the control system of the electronic lock according to the embodiment of the present invention, and details are not described herein again.
In summary, according to the control method of the electronic lock of the embodiment of the invention, after receiving the electronic lock locking instruction, the controller inputs a first forward driving pulse voltage signal with a pulse width of a first time to the electronic lock to control the electronic lock to be automatically locked, and after the electronic lock is automatically locked, a second forward driving pulse voltage signal with a pulse width of a third time is input to the electronic lock every second time, where the second time is greater than the first time, and the first time is greater than the third time, and the detection unit determines whether the electronic lock is manually unlocked after the electronic lock is automatically locked according to whether the status voltage signal output by the electronic lock is detected. Therefore, after the electronic lock is automatically locked, the state of the electronic lock is monitored in real time, the state of the electronic lock is accurately fed back, and the anti-theft function of the whole vehicle is perfected in a mode that the controller periodically sends a second forward driving pulse voltage signal.
Based on the same inventive concept, as shown in fig. 6, an embodiment of the present invention further provides a vehicle 1000 corresponding to the control system 100 of the electronic lock.
Specifically, according to the vehicle 1000 provided by the embodiment of the present invention, the control system 100 of the electronic lock is adopted, wherein the vehicle 1000 of the embodiment of the present invention may implement a specific implementation manner corresponding to the control system 100 of the electronic lock one to one.
