Detailed Description
Illustrative embodiments of the application include, but are not limited to, a vehicle anti-theft method, a motorized door controller, and a vehicle.
The terms mentioned in the present application are first described below.
(1) Vehicle body controller (Body Control Module, BCM)
BCM in an automobile refers to an electronic control unit for controlling an electrical system of a vehicle body, and common functions of BCM include controlling power windows, power rearview mirrors, air conditioners, headlights, turn signals, anti-theft systems, center locks, defrosters, and the like.
(2) Hall sensor
A hall sensor is a sensor that converts a changing magnetic field into a change in output voltage. Hall sensors can be used for measuring magnetic fields and also for measuring physical quantities which generate and influence magnetic fields, for example for position measurement, rotational speed measurement, current measurement, etc.
(3) System Base Chip (System Base Chip, SBC)
SBC is a stand-alone chip that includes features for power conversion, communications, monitoring diagnostics, security monitoring, and the like.
The technical solutions of some embodiments of the present application are described below with reference to the accompanying drawings.
It is to be understood that the door referred to in the present application may be any door of a vehicle, including a left side door, a right side door, a tail door, etc.
Next, first, the connection relation of the devices in the vehicle will be described with reference to fig. 1, and fig. 1 shows a schematic diagram of the connection relation of the devices, and as shown in fig. 1, the vehicle includes a hall sensor, a motor door controller, and a vehicle body controller. The Hall sensor is positioned in the vehicle door and used for detecting a displacement signal of the vehicle door. The electric vehicle door controller includes an interface device of a hall element, a main control chip (an example of the second processing module mentioned in the present application), and an SBC (an example of the first processing module mentioned in the present application). The SBC is communicatively coupled to the BCM via CAN or other means.
In some embodiments, when the automobile is stolen during sleep, for example, after the door lock body of the automobile is abnormally opened, for example, pried, the SBC receives a signal generated by the Hall sensor and sends a wake-up signal to the main control chip, after the main control chip is switched to a working mode, the SBC sends an anti-theft alarm signal, the SBC transmits the alarm signal to the BCM through CAN communication, and the BCM triggers the anti-theft alarm.
However, when the door is closed, there may be a situation that the door is not closed, that is, there is an initial displacement of the door, so that the hall sensor for monitoring the displacement of the door is in a critical state for generating the hall signal, that is, the hall sensor detects the displacement, but the displacement is not large enough, and the generated hall signal is unstable. If the automobile body is blown by wind or other vehicles pass by the automobile body, the automobile door of the automobile is further displaced, the Hall sensor can generate signals, and the network of the whole automobile is awakened by mistake, so that the anti-theft alarm is in a false alarm condition.
When the Hall sensor is in a critical state for generating a Hall signal, the door of the automobile is further displaced, so that the electric door controller is awakened by mistake from a sleep state, and after the awakening by mistake is released, the electric door controller enters the sleep state again. Because the automobile door has initial displacement, when the external environment changes, the electric automobile door controller can be caused to switch from a sleep state to a repeatedly circulated state of being awakened, so that the dark current of the automobile door controller is increased and the dark current of the whole automobile is increased, and the problems of power shortage of the storage battery of the whole automobile, reduction of the endurance mileage of the electric automobile and the like are caused.
In order to solve the problems, the application provides a vehicle anti-theft method which is applied to an electric vehicle door controller, wherein the electric vehicle door controller is connected with a Hall sensor; the electric vehicle door controller comprises a first processing module (such as SBC mentioned in the application) and a second processing module (such as a main control chip mentioned in the application), wherein the first processing module and the second processing module are respectively connected to a first output end of the Hall sensor through a first signal channel and a third signal channel, and are respectively connected to a second output end of the Hall sensor through a second signal channel and a fourth signal channel; the method comprises the following steps: controlling the first processing module and the second processing module to enter a low power consumption mode and a sleep mode respectively; when the first processing module receives a signal generated by the Hall sensor based on the first signal channel, a wake-up signal is sent to the second processing module; the second processing module is switched from the sleep mode to the working mode based on the wake-up signal, and when the fact that only the third signal channel has a signal and the signal does not meet the first preset standard is determined, the wake-up signal is determined to be an invalid wake-up signal, and the anti-theft alarm is controlled not to be executed; when the wake-up signal is determined to be an invalid wake-up signal, the second processing module is switched from the working mode to the sleep mode, and the first processing module is controlled to close the first signal channel, and only signals generated by the Hall sensor are received through the second signal channel.
Therefore, when the signal generated by the Hall sensor is detected to be an invalid wake-up signal, the anti-theft alarm is not executed, and the accuracy of the anti-theft alarm of the vehicle is improved; and the signal channel for generating the interference signal is closed, so that the electric quantity of a battery in the vehicle can be saved.
In some embodiments, performing the burglar alarm includes sending an alarm message, such as a voice prompt to the owner of the vehicle, to the owner of the vehicle so that the owner quickly knows that the vehicle is in a stolen state.
The vehicle anti-theft method according to the present application will be described with reference to fig. 2. Fig. 2 shows a schematic flow chart of a vehicle anti-theft method, as shown in fig. 2, comprising the steps of:
S101: and controlling the first processing module and the second processing module to enter a low power consumption mode and a sleep mode respectively.
When the automobile is in a sleep state, the first processing module and the second processing module are controlled to enter a low-power consumption mode and a sleep mode respectively.
The first processing module in the low power consumption mode may receive a signal sent by the hall sensor.
S102: and when the first processing module receives the signal generated by the Hall sensor based on the first signal channel, a wake-up signal is sent to the second processing module.
When the automobile is in a sleep state, the first processing module sends a wake-up signal to the second processing module based on the signal generated by the Hall sensor received by the first signal channel.
S103: the second processing module is switched from the sleep mode to the working mode based on the wake-up signal, and when the fact that only the third signal channel has a signal and the signal does not meet the first preset standard is determined, the wake-up signal is determined to be an invalid wake-up signal, and the anti-theft alarm is controlled not to be executed.
In some embodiments, after the second processing module switches to the working mode, if signals are detected to exist in the third signal channel and the fourth signal channel, and both the signals meet the first preset standard, the wake-up signal is determined to be a valid wake-up signal, and the anti-theft alarm is executed.
After the car door is closed, the position of the magnetic pole on the magnetic ring on the motor rotor is just above the Hall sensor, so that the Hall sensor for monitoring the displacement of the car door is in a critical state for generating or not generating a Hall signal. If the automobile body is blown by wind or other vehicles pass by the automobile body, the automobile door of the automobile is further displaced, the Hall sensor can generate Hall signals, and the network of the whole automobile is awakened by mistake, so that the anti-theft alarm is in a false alarm condition.
Therefore, in the application, the occurrence of the abnormal vehicle door is determined only when the signals of the third signal channel and the fourth signal channel are detected to exist and the pulse number reaches the preset standard in the preset time, so that the condition of false alarm of the anti-theft alarm is avoided. The preset standard may be: and determining that the vehicle door is abnormal when the pulse signals of the third signal channel and the fourth signal channel reach Y in X seconds, wherein specific data of the X seconds and the Y pulse signals can be set according to the needs, and the vehicle door control method is not limited.
In some embodiments, after the second processing module switches to the working mode, if signals of the third signal channel and the fourth signal channel are detected to exist, and the signals of the third signal channel and/or the fourth signal channel do not meet the first preset standard, the anti-theft alarm is not executed, and the second processing module switches from the working mode to the sleep mode.
S104: when the wake-up signal is determined to be an invalid wake-up signal, the second processing module is switched from the working mode to the sleep mode, and the first processing module is controlled to close the first signal channel, and only signals generated by the Hall sensor are received through the second signal channel.
Due to the spatial arrangement of the third and fourth signal paths in the motor vehicle, it may occur that only the third signal path has a signal, while the signal generated by the third signal path generally fails to meet the predetermined criterion and the fourth signal path generally has no signal. For example, when the second processing module wakes up by the signal generated by the first signal channel, the presence signal of the third signal channel is detected, and the signal generated by the third signal channel does not reach the preset standard, and the fourth signal channel does not have a signal. At this time, the first processing module is controlled to close the first signal channel, and only signals generated by the Hall sensor are received through the second signal channel.
In some embodiments, the first signal path is re-opened when the second predetermined criterion is met; wherein the second preset criteria comprises: when the second processing module is awakened by an awakening source of the non-Hall sensor; or when the second processing module is effectively awakened by the Hall sensor. For example, the second processing module is awakened by the CAN communication signal, or the first signal channel is restarted when the whole vehicle is powered on.
And when the automobile determines that the automobile door is abnormal, performing anti-theft alarm. For example, the car body gives an alarm, or the car sends an anti-theft alarm to the mobile phone end of the car owner, for example, a voice prompt of the alarm is sent, so that the car owner can quickly know that the car is in a theft state.
Therefore, when the signal generated by the Hall sensor is detected to be an invalid wake-up signal, the anti-theft alarm is not executed, and the accuracy of the anti-theft alarm of the vehicle is improved; and the signal channel for generating the interference signal is closed, so that the electric quantity of a battery in the vehicle can be saved.
A circuit diagram of the hall sensor connection to the electric vehicle door controller is described below in conjunction with fig. 3. Fig. 3 shows a schematic diagram of a hall sensor connection to a motorized door controller. When the electric vehicle door controller works normally, the main control chip detects signals of the two signal channels, namely a third signal channel and a fourth signal channel, and the signals are used for measuring the position of the vehicle door when the vehicle door is opened and closed.
As shown in fig. 3, the third signal path includes a third circuit unit, which is connected to the first output terminal of the hall sensor and the second processing module, respectively. The third circuit unit includes a capacitor C1, a resistor R11, a resistor R3, a resistor R12, and a capacitor C6. The signal in the third signal path (i.e., the HALL1 signal) may be used to measure the position of the door when it is open or closed. Specifically, the first end of the capacitor C1 is grounded, the second end is connected to the first end of the resistor R1, and the second end of the resistor R1 is grounded. The first end of the resistor R3 is connected with the first end of the R1, and the second end of the resistor R3 is connected with a main control chip of the electric vehicle door controller. The first end of the resistor R11 is connected with the first end of the resistor R3, and the second end of the resistor R11 is grounded. The first end of the resistor R12 is connected with the first end of the resistor R4, and the second end of the resistor R12 is grounded. The first end of the capacitor C6 is connected with the second end of the resistor R3, and the second end is grounded. The second end of the resistor R3 is connected with the main control chip of the electric vehicle door controller, and the signal of the Hall sensor is transmitted to the main control chip of the electric vehicle door controller through the circuit.
As shown in fig. 3, the fourth signal path includes a fourth circuit unit, and the fourth circuit unit is connected to the second output terminal of the hall sensor and the second processing module, respectively. The fourth circuit unit includes a capacitor C2, a resistor R4, and a capacitor C7. The signal in the fourth signal path (i.e., HALL2 signal) can be used to measure the position of the door when it is open or closed. Specifically, the first end of the capacitor C2 is grounded, the second end is connected to the first end of the resistor R2, and the second end of the resistor R2 is grounded. The first end of the resistor R4 is connected with the first end of the resistor R2, and the second end of the resistor R4 is connected with a main control chip of the electric vehicle door controller. The first end of the capacitor C7 is connected with the second end of the resistor R4, and the second end of the capacitor C7 is grounded. The second end of the resistor R4 is connected with the main control chip of the electric vehicle door controller, and the signal of the Hall sensor is transmitted to the main control chip of the electric vehicle door controller through the circuit.
As shown in fig. 3, the first signal path includes a first circuit unit, which is connected to the first output terminal of the hall sensor and the first processing module, respectively. The first circuit unit comprises a capacitor C1, a resistor R6 and a capacitor C4, and is used for generating a pulse signal according to vibration displacement generated by the vehicle door when the vehicle is in a sleep state. Specifically, the first end of the resistor R1 is connected to the first end of the resistor R6, the second end of the resistor R6 is connected to the first end of the capacitor C4, and the second end of the capacitor C4 is grounded. The first end of the capacitor C4 is also connected to the SBC of the electric vehicle door controller, and the signal of the Hall sensor is transmitted to the SBC of the electric vehicle door controller through the circuit. As shown, the first signal path and the third signal path are partially repeated, such as by sharing the capacitor C1 and the resistor R1.
As shown in fig. 3, the second signal path includes a second circuit unit, which is connected to the second output terminal of the hall sensor and the first processing module, respectively. The second circuit unit comprises a capacitor C2, a resistor R5 and a capacitor C3, and is used for generating another pulse signal according to vibration displacement generated by the vehicle door when the vehicle is in a sleep state. Specifically, the first end of the resistor R5 is connected to the first end of the resistor R2, the second end of the resistor R5 is connected to the first end of the capacitor C3, and the second end of the capacitor C3 is grounded. The first end of the capacitor C3 is also connected to the SBC controlled by the electric vehicle door, and the signal of the Hall sensor is transmitted to the SBC controlled by the electric vehicle door through the circuit. As shown, the second signal path and the fourth signal path are partially repeated, such as by sharing the capacitor C2 and the resistor R2.
When the automobile is in a sleep state, whether signals are input to the first signal channel and the second signal channel or not is monitored through the SBC. When SBC detects that the first signal channel or the second signal channel is input with signals, waking up the main control chip; that is, when any of the first and second signal paths has a signal, the SBC wakes up the main control chip. And when the main control chip is awakened, detecting whether signals exist in the third signal channel and the fourth signal channel. When the main control chip detects that the third signal channel and the fourth signal channel both have signals and meet the first preset standard, the main control chip determines that the wake-up signal is an effective wake-up signal, wakes up the network of the whole car through the SBC, sends a request of anti-theft alarm to the BCM, and triggers the BCM to execute the anti-theft alarm.
The anti-theft method according to the present application will be described in detail with reference to fig. 4. Fig. 4 shows a flow diagram of an anti-theft method. The method comprises the following steps:
S201: the electric vehicle door controller enters a sleep state.
When the automobile enters a sleep state, the electric door controller enters the sleep state. When the electric vehicle door controller enters a sleep state, the SBC in the electric vehicle door controller is in a low power consumption mode, and the main control chip is in a sleep mode.
S202: and judging whether a Hall signal is input.
SBC determines whether a hall signal is input, as shown in fig. 3, and determines whether signals exist in the second signal path and the first signal path when the automobile is in a sleep state.
S203: the electric vehicle door controller wakes up.
When judging that the Hall signal is input, namely when SBC receives the signal sent by the Hall sensor, a wake-up signal is sent to the main control chip, and the main control chip is waken up, so that the electric vehicle door controller wakes up. When any one of the first signal channel and the second signal channel has a signal, the main control chip is awakened.
S204: signals generated by either the first signal path or the second signal path are recorded.
The electric vehicle door controller records whether an input signal is a first signal channel or a second signal channel, and records the first signal channel when the first signal channel generates a signal; when the second signal path generates a signal, the second signal path is recorded.
S205: and judging whether the wake-up is wrong.
If the third signal channel and the fourth signal channel are provided with Hall pulse inputs and reach preset standards, for example, the pulse number reaches b in a second, the effective wake-up is judged; if the third signal channel and the fourth signal channel have Hall pulse inputs, but any signal channel does not meet the preset standard, for example, the pulse number does not reach b in a second, and the invalid wake-up signal is judged.
If only 1 signal channel has Hall pulse input and the signal does not accord with the pulse number reaching b in a second, the wake-up signal is determined to be invalid wake-up signal.
When there are signals in both the third signal path and the fourth signal path, the process goes to step S207; if only one signal channel has a hall signal, for example, only the third signal channel has a signal, and the signal does not meet the first preset standard, the signal is judged to be a false wake-up signal, and the process goes to step S206.
S206: in SBC, the signal channel that generates the signal is closed, the wake-up request is no longer accepted, while the other signal channel is maintained open, and the wake-up request is received.
For example, when it is detected that only the third signal path exists and the signal does not reach the preset standard, the first signal path is closed, the wake-up request is not accepted any more, but only the second signal path is kept open, the wake-up request is accepted, and the process goes to step S201.
In step S206, it is equivalent to that only one output end of the hall sensor has hall signal output, and the output signal is not strong enough (for example, X is not satisfied to slightly reach the requirement of Y pulses), so that it can be considered that the output end is precisely located at the critical position where the hall signal is generated or not generated when the door is closed, so that the signal channel corresponding to the output end is closed to avoid the main control chip from being repeatedly awakened. In addition, in a further embodiment, the operation of closing the signal path may be performed after a predetermined number of consecutive occurrences in a similar manner.
S207: signals in the third signal path and the fourth signal path are counted.
When signals exist in the third signal channel and the fourth signal channel, the electric vehicle door controller counts the third signal channel and the fourth signal channel. In the application, a software logic module is added in an electric vehicle door controller to count Hall pulse signals. In some embodiments, the counting of the hall signals can also be performed by adding a counter module in the electric vehicle door controller, and the application is not limited to the counting method of the signals.
S208: and judging whether an alarm condition is reached.
It is determined whether an alarm condition is reached, for example, within X seconds, the number of pulses in the third signal path and the fourth signal path reaches Y.
The electric vehicle door controller calculates the pulse number of the third signal channel and the fourth signal channel and judges whether the pulse number of the third signal channel and the fourth signal channel reaches Y in X seconds. For example, when it is determined that the pulse numbers of the third signal path and the fourth signal path both reach Y in X seconds, it is determined that the alarm condition is reached, and the process goes to step S209; and judging that the number of square waves of the third signal channel and the fourth signal channel is not Y in X seconds, judging that the alarm condition is not met, and turning to step S201.
In some embodiments, the specific data of the X seconds and Y pulse signals may be set according to the need, and the present application is not limited.
S209: and waking up the whole vehicle network and sending out an alarm request.
When the signals of the third signal channel and the fourth signal channel, namely the number of square waves, reaches Y in X seconds, the electric vehicle door controller wakes up the whole vehicle network and sends out an alarm request. For example, the electric door controller may send a request for an burglar alarm to the BCM through the CAN.
S210: the vehicle body controller gives an alarm.
When an alarm request is received, the BCM issues an alarm.
Therefore, when the signal generated by the Hall sensor is detected to be an invalid wake-up signal, the anti-theft alarm is not executed, and the accuracy of the anti-theft alarm of the vehicle is improved; and the signal channel for generating the interference signal is closed, so that the electric quantity of a battery in the vehicle can be saved.
Therefore, false wake-up of the whole vehicle network is avoided, false alarm of the anti-theft alarm is avoided, and alarm time is accurate. And when the signal generated by the output end can not reach the preset standard, the SBC closes the detection of the signal of the output end, thereby avoiding the repeated circulation of the electric vehicle door controller from the sleep state to the wrongly awakened state, and protecting the electric quantity of the storage battery of the whole vehicle and the cruising level of the electric vehicle.
