Description
Technical Field
The invention relates to the technical field of vehicle safety, in particular to a system and a method for cutting off vehicle power and a vehicle.
Background
At present, many vehicles have a remote anti-theft function, namely, a vehicle controller (such as a vehicle owner) can achieve the purposes of vehicle security and theft prevention through a remote power cut-off method. On one hand, before the vehicle engine is ignited, the key circuit can be cut off by controlling the vehicle relay, so that the vehicle can not be ignited and can not run; on the other hand, after the vehicle is ignited and runs, the key circuit can be cut off by controlling the vehicle relay, so that the vehicle loses power and stops running.
In the related art, as shown in fig. 1, a vehicle power cut-off scheme may include a data transmission module, a control module, a power supply module, and a relay. The data transmission module receives a power cut-off instruction sent by a vehicle controller and sends the power cut-off instruction to the control module, the control module receives the instruction and immediately executes the instruction to control the relay to be switched off (the power supply module supplies power), and the relay is usually installed on a vehicle key circuit, so that the vehicle key circuit is switched off when the relay is switched off, and the vehicle cannot ignite or loses power. The relay generally adopts a normally closed relay, i.e., the relay is normally closed when not powered and is opened (disconnected) when powered. The other normally open relay is normally open under the condition of no power supply and closed under the condition of power supply, and the normally open relay is more power-consuming and is not generally used in the scenes of vehicle security and theft prevention. The key line mainly refers to a line for connecting equipment such as a vehicle oil pump, a master control computer, a vehicle door window, a key hole and the like, and once the line is cut off, the vehicle cannot ignite or loses power. The power supply module mainly refers to a vehicle storage battery, and the storage battery is required to be continuously supplied with power when the relay is disconnected, so that the power consumption is increased.
The above-described prior art vehicle power cut-off scheme has the following disadvantages:
1) the vehicle controller is difficult to know whether the vehicle is subjected to unauthorized driving conditions (such as theft, child misopening and the like) in the future in advance, and the relay can only be switched off after the vehicle is parked every time, so that the vehicle cannot be ignited, but the relay is continuously switched off, so that the power consumption is high, the storage battery is influenced to supply power for other key equipment, the driving safety is influenced due to poor power supply, and the maintenance cost is increased.
2) After the vehicle controller knows that the vehicle is subjected to unauthorized driving, the relay needs to be disconnected in order to lose power of the vehicle, and before the vehicle controller finds the vehicle, the relay needs to be kept in a disconnected state to prevent the vehicle from being subjected to unauthorized driving for the second time, the continuous power supply is very power-consuming, and the vehicle is likely to be incapable of being switched back by the vehicle controller due to the fact that the electric quantity is exhausted, so that the maintenance cost is increased.

The system and method for cutting off the power of a vehicle according to the embodiment of the present invention will be described with reference to the accompanying drawings.
Fig. 2 is a block diagram of a system for cutting off power of a vehicle according to an embodiment of the present invention. As shown in fig. 2, the system 100 for cutting off power of a vehicle includes: a data transmission module 110, a control module 120, a data acquisition module 130 and a relay 140.
The control module 120 is connected to the data transmission module 110, the data acquisition module 130 and the relay 140, the relay 140 is connected to a power system circuit of the vehicle, the power system circuit is a key circuit of the vehicle, and the relay 140 controls the power system circuit to disconnect the power system circuit, thereby realizing the cut-off of the vehicle power.
Specifically, the data transmission module 110 receives a command for cutting off the power of the vehicle from a user (i.e., a vehicle controller, such as a vehicle owner), and transmits the command to the control module 120; the data acquisition module 130 is connected to an OBD interface of the vehicle, and is configured to acquire vehicle state information through the OBD interface and transmit the vehicle state information to the control module 120; the control module 120 receives a command for cutting off the power of the vehicle and the vehicle state information, and controls the relay 140 to be turned off when the vehicle state information includes the power-on data of the whole vehicle, so that a power system circuit of the vehicle is opened, and the vehicle cannot ignite or loses power to cut off the power of the vehicle. It is understood that the OBD interface has a function of acquiring vehicle status information, and the data acquisition module 130 is connected to the OBD interface, and may acquire the vehicle status information by acquiring the OBD interface information and then transmit the vehicle status information to the control module 120.
In one embodiment of the present invention, the data transmission module 110 also receives a command from a user that does not require the vehicle to be powered off and transmits the command to the control module 120; the control module 120 receives an instruction that the power of the vehicle is not required to be cut off, or when the vehicle state information does not contain the power-on data of the whole vehicle, the control relay 140 is kept closed, namely the power of the vehicle is not cut off, and the vehicle can run normally.
Specifically, when the vehicle is in the powered state, the vehicle state information data acquired by the data acquisition module 130 through the OBD interface includes powered data of the entire vehicle, otherwise, that is, when the vehicle is not powered, the vehicle state information data acquired by the data acquisition module 130 through the OBD interface does not include powered data of the entire vehicle.
In one embodiment of the present invention, the system 100 for cutting power of a vehicle further comprises a power supply module. The power supply module is connected with the relay 140 to supply power to the relay 140 when the relay 140 is turned on, so that the relay 140 is turned off; the control module 120 is connected to the power supply module and is configured to control the power supply module to be turned on or off. As described above, when the vehicle state information includes the power-on data of the entire vehicle and the command requires power cut-off, the control module 120 controls the power supply module to be turned on to supply power to the relay 140, so that the relay 140 is turned off, thereby disconnecting the key circuit of the vehicle and preventing the vehicle from being ignited or losing power; when the vehicle state information does not contain the power-on data of the whole vehicle or the command does not require power cut-off, the control module 120 controls the power supply module to be closed, the relay 140 is not supplied with power, the relay 140 is kept closed, and the vehicle can be normally driven at the moment. Wherein, the power supply module is for example the storage battery of vehicle.
In other words, after the data transmission module 110 receives the command sent by the vehicle controller and sends the command to the control module 120, the control module 120 acquires the OBD interface information (the acquisition frequency is flexibly set according to different scenes) through the data acquisition module 130, that is, acquires the vehicle status information. When the vehicle state information in the OBD interface information contains the vehicle power-on data and the command requires power cut-off, the control module 120 executes the power cut-off command, the control relay 140 is turned off (power is supplied by the power supply module at this time), and the relay 140 is connected and controls the vehicle key circuit, so that the relay 140 is turned off, that is, the vehicle key circuit is turned off, the vehicle cannot be ignited or loses power, and the vehicle power is cut off; when the vehicle state information in the OBD interface information does not include the vehicle-finished power-on data or the command does not require power cut-off, the control module 120 does not execute the power cut-off command, the relay 140 remains closed (at this time, the power supply module does not supply power), and the vehicle can be driven normally.
In one embodiment of the present invention, the system 100 for cutting off power of a vehicle further comprises a positioning module for positioning the vehicle, providing vehicle position information, and facilitating the user to find the vehicle in time.
In one embodiment of the present invention, the control module 120 may be installed in a vehicle, and the control module 120 may be integrally provided with the positioning module, thereby saving space in the vehicle.
In one embodiment of the present invention, the data transmission module 110 is further configured to transmit vehicle-related information to a user for the user to manage the vehicle. The vehicle-related information includes at least: vehicle status information and relay status information. In other words, the data transmission module 110 may receive and transmit a command (e.g., a command to cut off the power of the vehicle/a command not to cut off the power of the vehicle), and may receive and transmit vehicle-related information, e.g., vehicle state information, relay state information, etc., and transmit the data to the vehicle controller so that the vehicle controller manages the vehicle.
That is to say, the control module 120 acquires the OBD interface information through the data acquisition module 130, and when the vehicle state information in the OBD interface information includes the vehicle powered on data and the command requires power cut-off, the control module 120 executes the power cut-off command, controls the relay 140 to be turned off, and sends the received vehicle state information, relay state information and the like to the data transmission module 110, and timely informs the vehicle controller that the vehicle is being driven by unauthorized driving (such as theft, child misopening and the like), so as to facilitate the vehicle controller to manage the vehicle.
In one embodiment of the present invention, the relay 140 may be integrally disposed within the control module 120. Further, the relay 140 may be one or more.
That is, one control module 120 is connected to one OBD interface through the data acquisition module 130, and one control module 120 may control one or more relays 140.
In a specific embodiment, according to different usage scenarios and different vehicle type requirements, the embodiment of the present invention may use only one OBD interface, and one control module 120 controls one relay 140, for example, as shown in fig. 3; one OBD interface may also be used, with one control module 120 controlling multiple relays 140, such as shown in fig. 4.
Specifically, the embodiment of the invention can control the relay 140 to disconnect the critical line through the control module 120, so as to ensure the safety of the vehicle. For example, all relays 140 may be turned off at the same time, or one or more of the relays 140 may be turned off.
The scheme of the plurality of relays 140 is favorable for improving the security and theft prevention capability of the vehicle and the security and protection capability of personnel, and under the condition that one relay 140 fails, the acquisition of data such as vehicle state information and relay state information can be realized through other normally working relays 140, so that the execution of a power cut-off instruction is ensured, the safety of the vehicle is ensured, and the vehicle is prevented from being stolen or mistakenly opened.
As a specific example, the security and theft prevention operation principle of the system for cutting off the power of the vehicle according to the embodiment of the present invention will be described below.
When the ACC gear interface of the vehicle is in an ON state (such as when a driver merely inserts a key or presses an ACC gear button, and any method capable of electrifying the entire vehicle), the entire vehicle is in an electrified state, at this time, the vehicle is not ignited, but all the electrified devices in the vehicle, such as the ACC gear interface, lighting and signal lamps, alarm lamps, instruments, radios, audio auxiliary electrical devices and the like, are in an electrified state. In this state, the entire vehicle is not yet ignited. And in the whole vehicle power-on state, the vehicle state information displayed by the OBD interface information comprises the vehicle whole vehicle power-on data. The embodiment of the invention monitors the vehicle state information in the OBD interface information before the vehicle is ignited, and once the vehicle state information in the OBD interface information is found to contain the vehicle on-board power-on data, that is, it can be quickly known that an unauthorized person sets the vehicle state to the ACC step interface ON state (for example, when the driver merely inserts a key or presses an ACC step button, and the entire vehicle is powered ON by any method), at this time, when the received command is a power cut-off command, it is automatically determined that the vehicle is about to be driven by an unauthorized person (e.g., about to ignite), the control module 120 executes the power cut-off command, the control relay 140 is turned off (power is supplied to the power supply module at this time), and since the relay 140 is connected and controls a key circuit of the vehicle, the cut-off relay 140 turns off the key circuit of the vehicle, so that the vehicle cannot ignite, and the power of the vehicle is cut off, thereby preventing the unauthorized person from driving the vehicle. On the contrary, when the vehicle state information in the OBD interface information does not include the vehicle powered-on data, that is, it indicates that the vehicle is not in the vehicle powered-on state, at this time, the system will automatically determine that the vehicle is not driven by an unauthorized person (for example, ignition is about to occur), the control module 120 does not execute the power cut-off instruction, the relay 140 remains connected, the power supply module does not need to supply power, at this time, the vehicle power is not cut off, and the vehicle can run normally.
Therefore, in the system for cutting off the vehicle power, after a vehicle controller sends a vehicle power cutting-off instruction, the vehicle can keep the relay connected (without power supply) all the time, and only when a certain condition is met, the relay is disconnected, so that the power consumption is very low, namely the relay is disconnected when unauthorized driving really occurs. In addition, the relay does not need to be continuously disconnected and the continuous power supply is maintained before a vehicle controller finds the vehicle, and the relay needs to be disconnected only when the vehicle controller is actually driven twice without authorization, so that the energy consumption is greatly reduced, and the maintenance cost is reduced. Meanwhile, the system for cutting off the power of the vehicle has strong applicability and wide application range, can be applied to the fields of vehicle security and theft prevention, and can also be applied to the field of personnel security, such as the prevention of old people, children or unauthorized personnel from driving the vehicle without permission.
According to the system for cutting off the power of the vehicle, the OBD interface and the control module are connected, the vehicle state information under the condition that the whole vehicle is electrified is obtained through the OBD interface, the on-off of the relay is controlled accordingly, the relay can be cut off when the vehicle is in unauthorized driving, the relay is kept in a closed circuit in other states, namely, a vehicle controller does not need to continuously cut off the relay and maintain continuous power supply before finding the vehicle, and the relay is cut off only when the vehicle controller is in unauthorized driving for the second time, so that the power supply energy consumption of a storage battery is greatly reduced, the normal work of other key equipment of the vehicle is ensured, the driving safety is guaranteed, and the maintenance cost is reduced.
A further embodiment of the present invention also provides a vehicle. The vehicle comprises the system for cutting off the power of the vehicle according to any one of the embodiments of the invention. Therefore, the specific implementation manner of the vehicle according to the embodiment of the present invention is similar to the specific implementation manner of the system for cutting off the vehicle power according to the embodiment of the present invention, and please refer to the description of the system part specifically, and the detailed description is omitted here in order to reduce redundancy.
According to the vehicle provided by the embodiment of the invention, the OBD interface and the control module are connected, the vehicle state information under the condition that the whole vehicle is electrified is obtained through the OBD interface, and the on-off of the relay is controlled according to the information, so that the relay is disconnected when the vehicle is subjected to unauthorized driving, the relay is kept in a closed circuit in other states, namely, the relay does not need to be continuously disconnected and the continuous power supply is maintained before a vehicle controller finds the vehicle, and the relay is disconnected only when the vehicle is subjected to unauthorized driving for the second time in the true occurrence, so that the power supply energy consumption of a storage battery is greatly reduced, the normal work of other key equipment of the vehicle is ensured, the driving safety.
In addition, other configurations and functions of the vehicle according to the embodiment of the present invention are known to those skilled in the art, and are not described in detail in order to reduce redundancy.
A further embodiment of the present invention is also directed to a method of shutting off power to a vehicle.
FIG. 5 is a flow chart of a method of powering down a vehicle according to one embodiment of the present invention. As shown in fig. 5, the method for cutting off the power of the vehicle includes the following steps:
step S1: the data transmission module receives a command of cutting off the vehicle power sent by a user and transmits the command to the control module.
Step S2: the data acquisition module acquires vehicle state information through an OBD interface of the vehicle and transmits the vehicle state information to the control module.
Step S3: the control module receives an instruction for cutting off the power of the vehicle and the vehicle state information, and controls the relay to be switched off when the vehicle state information contains the electrified data of the whole vehicle, so that a power system circuit of the vehicle is switched on, and the power of the vehicle is cut off, wherein the relay is connected with the power system circuit of the vehicle.
In one embodiment of the invention, the method further comprises: the data transmission module also receives an instruction which is sent by a user and does not need to cut off the power of the vehicle, and transmits the instruction to the control module; the control module receives an instruction that the power of the vehicle is not required to be cut off, or when the vehicle state information does not contain the electrified data of the whole vehicle, the control module controls the relay to be closed, namely the power of the vehicle is not cut off, and the vehicle can normally run.
Specifically, when the vehicle is in the power-on state, the vehicle state information data acquired by the data acquisition module through the OBD interface includes the power-on data of the entire vehicle, otherwise, when the vehicle is not powered on, the vehicle state information data acquired by the data acquisition module through the OBD interface does not include the power-on data of the entire vehicle.
In other words, after the data transmission module receives the instruction sent by the vehicle controller and sends the instruction to the control module, the control module acquires the OBD interface information (the acquisition frequency is flexibly set according to different scenes) through the data acquisition module, that is, the vehicle state information is acquired. When the vehicle state information in the OBD interface information contains the vehicle power-on data and the command requires power cut-off, the control module executes the power cut-off command, controls the relay to be switched off (power is supplied by the power supply module at the moment), and switches off the relay, namely the key circuit of the vehicle because the relay is connected with and controls the key circuit of the vehicle, so that the vehicle cannot be ignited or loses power, and the power of the vehicle is cut off; when the vehicle state information in the OBD interface information does not contain the vehicle power-on data or the command does not require power cut-off, the control module does not execute the power cut-off command, the relay is kept closed (at the moment, the power supply module does not supply power), and the vehicle can be normally driven.
In one embodiment of the invention, the method further comprises: the data transmission module transmits the vehicle-related information to the user so that the user can manage the vehicle. The vehicle-related information includes at least: vehicle status information and relay status information. In other words, the data transmission module may receive and transmit a command (e.g., a command to cut off the power of the vehicle/a command not to cut off the power of the vehicle), and may receive and transmit vehicle-related information, e.g., vehicle state information, relay state information, etc., and transmit the data to the vehicle controller so that the vehicle controller manages the vehicle.
Specifically speaking, the control module obtains the OBD interface information through the data acquisition module, and when the vehicle state information in the OBD interface information contains the vehicle power-on data and the command requires power to be cut off, the control module executes the power cut-off command, controls the relay to be disconnected, and sends the received vehicle state information, the relay state information and the like to the data transmission module, and timely informs a vehicle controller that the vehicle is subjected to unauthorized driving (such as theft, child misopening and the like), so that the vehicle controller can conveniently manage the vehicle.
In one embodiment of the invention, the relay may be integrated within the control module. Further, the relay may be one or more.
That is, a control module is connected to an OBD interface through a data acquisition module, and a control module may control one or more relays.
In the specific embodiment, according to different use scenes and different vehicle type requirements, only one OBD interface can be used, and one relay is controlled by one control module; one OBD interface may also be used, with one control module controlling multiple relays.
The scheme of selecting the plurality of relays is favorable for improving the security and theft prevention capability of the vehicle and the security and protection capability of personnel, and under the condition that one relay is in fault, the acquisition of data such as vehicle state information and relay state information can be realized through other normally working relays, so that the execution of a power cut-off instruction is ensured, the safety of the vehicle is ensured, and the vehicle is prevented from being stolen or opened by mistake.
As a specific example, when the ACC gear interface of the vehicle is in an ON state (such as when the driver merely inserts a key or presses an ACC gear button, and any method that can energize the entire vehicle), the entire vehicle is in an energized state, at which time the vehicle is not ignited, but all of the energizable devices in the vehicle, such as the ACC gear interface, the auxiliary electrical devices such as lighting and signal lights, warning lights, instruments, radios, and stereos, etc., are in an energized state. In this state, the entire vehicle is not yet ignited. And in the whole vehicle power-on state, the vehicle state information displayed by the OBD interface information comprises the vehicle whole vehicle power-on data. The embodiment of the invention monitors the vehicle state information in the OBD interface information before the vehicle is ignited, and once the vehicle state information in the OBD interface information is found to contain the vehicle on-board power-on data, that is, it can be quickly known that an unauthorized person sets the vehicle state to the ACC step interface ON state (for example, when the driver merely inserts a key or presses an ACC step button, and the entire vehicle is powered ON by any method), at this time, when the received command is a power disconnection command, the vehicle is automatically judged to be about to be driven by unauthorized people (such as about to ignite), the control module executes the power disconnection command, the control relay is disconnected (power is supplied by the power supply module at the moment), and the relay is connected and controls the key circuit of the vehicle, so that the key circuit of the vehicle is disconnected by disconnecting the relay, the vehicle cannot be ignited, the power of the vehicle can be disconnected, and the unauthorized people are prevented from driving the vehicle. On the contrary, when the vehicle state information in the OBD interface information does not include the vehicle powered-on data, that is, it indicates that the vehicle is not in the vehicle powered-on state, at this time, the system will automatically determine that the vehicle is not driven by an unauthorized person (for example, ignition is about to occur), the control module does not execute the power cut-off instruction, the relay remains connected, the power supply module does not need to supply power, at this time, the vehicle power is not cut off, and the vehicle can run normally.
Therefore, in the system for cutting off the vehicle power, after a vehicle controller sends a vehicle power cutting-off instruction, the vehicle can keep the relay connected (without power supply) all the time, and only when a certain condition is met, the relay is disconnected, so that the power consumption is very low, namely the relay is disconnected when unauthorized driving really occurs. In addition, the relay does not need to be continuously disconnected and the continuous power supply is maintained before a vehicle controller finds the vehicle, and the relay needs to be disconnected only when the vehicle controller is actually driven twice without authorization, so that the energy consumption is greatly reduced, and the maintenance cost is reduced. Meanwhile, the system for cutting off the power of the vehicle has strong applicability and wide application range, can be applied to the fields of vehicle security and theft prevention, and can also be applied to the field of personnel security, such as the prevention of old people, children or unauthorized personnel from driving the vehicle without permission.
It should be noted that a specific implementation manner of the method for cutting off vehicle power according to the embodiment of the present invention is similar to a specific implementation manner of the system for cutting off vehicle power according to the embodiment of the present invention, and please refer to the description of the system part specifically, and details are not described here again in order to reduce redundancy.
According to the method for cutting off the power of the vehicle, the OBD interface and the control module are connected, the vehicle state information under the condition that the whole vehicle is electrified is obtained through the OBD interface, the on-off of the relay is controlled accordingly, the relay can be cut off when the vehicle is in unauthorized driving, the relay is kept in a closed circuit in other states, namely, the relay does not need to be continuously cut off and continuously powered before a vehicle controller finds the vehicle, and the relay is cut off only when the vehicle controller is in unauthorized driving for the second time, so that the power supply energy consumption of a storage battery is greatly reduced, the normal work of other key equipment of the vehicle is ensured, the driving safety is guaranteed, and the maintenance cost is reduced.
