In addition, the processor is also used for receiving a locking instruction sent by the mobile terminal of the vehicle owner and controlling the vehicle locking unit to lock the vehicle according to the locking instruction. Of course, the processor may also directly output a locking instruction to control the lock unit to lock the vehicle when it is determined that the vehicle is in the abnormal state of theft of the vehicle.
In one embodiment of the invention, the device further comprises a built-in battery unit for charging by the vehicle body power supply, the built-in battery unit serving as a backup power supply for supplying power to all the modules when the vehicle body power supply is abnormally disconnected.
Specifically, the vibration sensor is a sensor for detecting vibration force, and the main working principle is that the vibration sensor is communicated with the power management unit through an IIC (integrated circuit bus), wakes up when vibration is detected, and sends vibration information to the power management unit, and the power management unit judges an abnormal state of the vehicle. The sensor may be a three-axis vibration sensor or a six-axis vibration sensor.

In this embodiment, the positioning unit is in simultaneous communication with the power management unit and the processor, and is configured to send positioning information to the power management unit and the processor at the same time. In addition, it is controlled by the power management unit to turn on and off the power. For example, after the vehicle vibrates, the power management unit may control the power supply of the positioning unit to be turned on, and then acquire positioning information of the positioning unit, and confirm whether the vehicle position moves. The positioning unit sends the positioning information to the processor, the processor can process and determine the moving track of the vehicle, and then the positioning information is sent to the mobile terminal through the wireless communication unit, so that a user can find the position of the stolen vehicle in time conveniently.
In this embodiment, the processor is mainly used for driving the display unit, and displaying the vehicle theft identifier, the vehicle speed, the rotation speed, the gear information, the user binding information and the mobile terminal information according to a preset interface display mode. The processor can also drive the positioning unit to run and record the position change and the movement track in the vibration duration time of the vehicle, and drive the WIFI to open and the Bluetooth to open, and the processor can respectively carry out the WIFI communication of big data and the Bluetooth communication of small data in a short distance with the mobile terminal. The processor may also drive the wireless communication unit to operate and upload the positioning information to a mobile terminal, such as a mobile phone, through a 4G (fourth generation mobile network) network.
In this embodiment, the wireless communication unit is mainly used to facilitate the vehicle instrument to realize 4G network communication, and send the status information and the alarm information of the vehicle to the mobile terminal. Meanwhile, after receiving the status information and the warning information, the user can confirm with the mobile terminal and then perform a locking operation on the vehicle and the vehicle meter through the wireless communication unit. The wireless communication unit in the embodiment controls the power supply to be turned on and off by the power supply management unit, and controls the operation by the processor.
In this embodiment, the lock unit belongs to the whole vehicle part and is powered by the vehicle body power supply. The power management unit in the vehicle instrument can control the power switch of the lock unit, and the power supply of the lock unit is always turned on under normal conditions. When a key is inserted, the locking of the vehicle can be released, so that the vehicle can be used normally. When the processor determines that the vehicle is in the abnormal state of vehicle theft, the processor can control the lock unit to lock the vehicle according to the locking instruction sent by the mobile terminal after the user confirms the vehicle in the mobile terminal manually, or control and close the power supply of the lock unit to enable the vehicle to enter the vehicle locking state, so that other users cannot normally use the vehicle.
In this embodiment, the vehicle body controller belongs to a main control unit of the vehicle, is powered by a vehicle body power supply, is connected and communicated with a processor in a vehicle instrument, and is responsible for controlling functions such as a vehicle gear, a vehicle speed, a rotating speed and the like.
In this embodiment, the first function of the power management unit is to control the on and off of the power of the processor, the positioning unit, the display unit, the wireless communication unit and other modules under specific conditions, so that the device meets the low power consumption requirement, and the second function is to accurately determine the abnormal state of the vehicle according to the vibration information provided by the vibration sensor, the movement track information provided by the positioning unit and the vehicle body power supply state information detected by the power management unit when the vehicle is determined to enter the sleep state according to the key state information.
It should be noted that, the built-in battery unit in this embodiment mainly includes a built-in lithium battery and a charging management chip, and its function is mainly used to charge the built-in battery unit through a vehicle body power supply. When the power supply of the vehicle body is disconnected abnormally, power supply driving for state recording and information reporting can be provided for the vehicle instrument.
The specific working principle of the vehicle function limiting and locking device of the embodiment of the invention is as follows:
when a user first purchases the vehicle, the vehicle needs to scan the code through the mobile terminal, realize WIFI and Bluetooth interconnection with the vehicle instrument, register in the mobile terminal, generate a product unique code and realize one-to-one authority binding. The vehicle instrument can realize binding with other mobile terminal users and obtain rights only after the user is unbound.
The vehicle instrument is driven to run through a vehicle body power supply and the built-in battery unit, when the power supply management unit detects that the key state of the vehicle is an insertion state, the power supply of the processor, the display unit, the positioning unit, the WIFI, the Bluetooth and the wireless communication unit of the vehicle instrument is started, so that the vehicle normally works, and the vibration state detected by the vibration sensor is defined as a normal state. And after the power management unit detects that the key state of the vehicle is unplugged, turning off the power supply of the processor, the display unit, the positioning unit, the WIFI, the Bluetooth and the wireless communication unit of the vehicle instrument, and entering a low-power consumption mode.
The power management unit can judge whether the vehicle is in an abnormal state or not through four factors of vibration force, vibration duration time, vehicle key state, positioning information and vehicle body power supply state detected by the vibration sensor. When abnormal vibration occurs, a power management unit in the vehicle instrument is awakened, and the power of the vehicle instrument positioning unit is started to work. When judging that the abnormal state is the stolen state of the vehicle according to the vibration force and the vibration duration sensed by the vibration sensor and the position information acquired by the positioning unit, the power supply management unit sequentially controls the power supply of the processor and the wireless communication unit to be started, sends the result of the stolen abnormal state of the vehicle to the mobile terminal through the wireless communication unit, gives an alarm message to a user, and simultaneously executes the following two possible schemes: the method comprises the steps that firstly, when a processor sends out alarm information through a wireless communication unit, a vehicle theft display identifier is directly preset in advance, the ID names of WIFI and Bluetooth are changed, the vehicle theft identifier is increased, when a vehicle instrument works normally, the corresponding vehicle theft display identifier is displayed on a display unit, and meanwhile, a vehicle body controller is controlled to limit the highest gear to be hung in and limit the vehicle speed to be smaller than a set value; and secondly, after receiving the alarm information or the state information and confirming the alarm information or the state information through the mobile terminal, the user can control the vehicle instrument to execute the limiting action. It should be noted that these two possible operations are customer-personalized selection operations.
Of course, the user can also lock the vehicle into a stolen state directly through the mobile terminal after receiving the state information or the alarm information. In an expandable manner, when a user finds that a stolen vehicle is parked nearby from the mobile terminal or in a special place such as the vicinity of a police department, the mobile terminal can be used for confirming and sending a locking instruction, and the vehicle instrument processor controls the vehicle lock unit to lock the vehicle or performs the following operations under the condition that the user safety is confirmed after receiving the locking instruction: and controlling the vehicle body controller to forcedly reduce the speed, when the vehicle speed is 0, turning off the power supply of the vehicle lock, controlling the vehicle body controller to turn off the power equipment, enabling the vehicle to be incapable of riding, informing the binding user to inform law enforcement personnel or go in person, and recovering the vehicle.
In one embodiment of the present invention, the abnormal state of the vehicle may further include a light vibration state, an abnormal vehicle moving state, a malicious vehicle moving state, and a battery stolen state.
The abnormal state in this embodiment refers to a state after the vehicle meter enters the low power consumption sleep mode when the power management unit of the vehicle meter detects that the key state is the unplugged state, that is, when the unplugged state information is detected.
In this embodiment, the power management unit may specifically determine the corresponding abnormal states according to the following information, respectively. For example, the power management unit may determine whether the vehicle is in a slightly vibrating state according to the vibration information. The power management unit can determine whether the vehicle is in an abnormal vibration state, an abnormal vehicle moving state, a malicious vehicle moving state and a vehicle stolen state according to the vibration information and the positioning information. The power management unit determines whether the vehicle is in a battery stolen state according to the vibration information and the vehicle body power supply state information.
Specifically, when the vibration sensor detects that the vibration force is small and the time is short, for example, |the vibration force|is less than or equal to 0.08g (g is gravitational acceleration), and the vibration duration is less than or equal to 1 minute, the power management unit detects and determines that the vibration is slight.
When the power management unit is awakened by the vibration detection unit, if the vibration force is detected to be larger, the time is shorter, or the vibration force is smaller, the time is longer, if the vibration force is larger than 0.08g, the vibration duration is less than or equal to 1 minute, or the vibration force is less than 0.08g, when the vibration duration is more than or equal to 1 minute, the power of the positioning unit is turned on, the positioning unit starts to position and judges whether the position is changed, and if the position is not changed, the power management unit determines that the position is in an abnormal vibration state. For example, in severe environments such as rainy and snowy weather, vibration force is small, and vibration duration is long, and at this time, an abnormal vibration state is determined.
Since there is generally a large vibration force when the vehicle is moving, there is a small vibration force and there is less possibility of a vibration state in which the position information is changed. When the power management unit detects vibration awakening, if the vibration force is detected to be larger and the time is longer, for example, the vibration force is more than 0.08g and less than or equal to 0.2g, the vibration duration is more than 1 minute and less than or equal to 10 minutes, the power management unit turns on the power supply of the positioning unit, starts positioning and judges the vibration state of the vehicle when the position has a range variation of 10 meters, and if the vehicle meets the condition of the vibration information within the range of the distance, the vehicle is determined to be in an abnormal vehicle moving state.
When the power management unit detects vibration wake-up, if the vibration force is detected to be large and the time is long, for example, 0.2g < |vibration force|, the vibration duration is less than 1 minute and less than or equal to 10 minutes, the power management unit turns on the power of the positioning unit, starts positioning and judges the vibration state of the vehicle when the position has 100 meters range variation, and if the vehicle meets the condition of the vibration information within the distance range, the vehicle is determined to be in a malicious vehicle moving state.
When the power management unit detects vibration awakening, if the vibration force is detected to be large, the vibration duration time is long and is not stopped, for example, 0.2g < |vibration force|, 10 minutes < vibration duration time, the power supply of the positioning unit is turned on, the positioning unit starts to position and judges the vibration state when the position continuously changes, and if the vehicle position continuously changes and vibration information meets the condition, the vehicle is determined to be in a vehicle stolen state.
Of course, when the processor determines that the vehicle is in the vehicle stolen state according to the abnormal state information, the processor can also control the display unit to display the vehicle stolen identifier and the user binding information and control the vehicle body controller to limit the highest gear to be hung in and the vehicle speed to be less than the set value. In addition, the processor can also receive a locking instruction sent by the mobile terminal of the vehicle owner and control the vehicle locking unit to lock the vehicle according to the locking instruction. Or when the user feedback is not received, directly outputting a locking instruction to control the vehicle lock unit to lock the vehicle.
When the power management unit detects vibration force, the power supply port of the vehicle body power supply is detected, and the voltage of the power supply port of the vehicle body power supply is detected to be zero in the preset time, the power management unit can determine that the vehicle is in a battery stolen state, namely, the vehicle is in a vehicle body power loss state. The preset time is very short, namely, the power management unit suddenly detects that the voltage of the power supply port of the power supply of the vehicle body is zero, and the vehicle can be determined to be in a battery stolen state. It is understood that the power management unit detects whether the vehicle body power supply is abnormally powered off or not at the same time when detecting that the vehicle is in a vibrating state.
Further, as shown in fig. 2, the invention also provides a vehicle function limiting and locking system, which comprises a mobile terminal and the vehicle function limiting and locking device, wherein the mobile terminal is used for remotely receiving the alarm information sent by the vehicle function limiting and locking device and giving an alarm to a user.
It should be noted that, mobile terminal application service software matched with vehicle instrument information service can be loaded in the mobile terminal of the embodiment, and the remote alarm function can be realized through the application service software.
In summary, the present invention provides a vehicle function restriction and locking device, which can accurately determine an abnormal state of a vehicle according to vibration force and vibration time, and position information, movement track information and power supply state information of a vehicle body power supply of the vehicle if vibration is detected after the vehicle is determined to enter a sleep state by key state information, and can timely send alarm information to a user when the vehicle is abnormal, so that the user can timely view and accurately understand the current state of the vehicle; when the vehicle is determined to be in the abnormal state of vehicle theft according to the abnormal state information, the controllable display unit can display the vehicle theft identification and the user binding information, so that after the purchaser identifies the identification and the information, loss caused by cheating is prevented, in addition, the vehicle body controller can be controlled to limit the highest gear to be hung in and the vehicle speed to be less than a set value, so that the vehicle function limitation is realized, and the vehicle is more intelligently assisted by a user to find the vehicle; the vehicle lock unit can lock the vehicle when the processor determines that the vehicle is in a vehicle stolen state or after receiving a locking instruction sent by a user through the mobile terminal, thereby being further convenient for assisting the user to search the vehicle and preventing the vehicle owner from losing; according to the method, when the vehicle is determined to be in the abnormal state of vehicle theft according to the abnormal state information, the names of the vehicle instrument WIFI and the Bluetooth are changed through the processor, and the vehicle theft identification is increased, so that when other mobile terminals are connected with the vehicle instrument WIFI and the Bluetooth, the vehicle is identified as the stolen vehicle. In addition, the invention also provides a vehicle function limiting and locking system which comprises the vehicle function limiting and locking device and the mobile terminal, wherein a user can know the current state of the vehicle through the mobile terminal and implement function limiting and locking on the vehicle, so that the user can be assisted in retrieving the vehicle conveniently.
