Description
Technical Field
[0001] The present application relates to the technical field of vehicle safety management, and in particular to a vehicle power failure emergency processing system, method, vehicle-mounted equipment and storage medium. Background Art
[0002] With the development of the automobile industry, the functions of modern automobiles are becoming increasingly intelligent. The realization of automobile functions mainly depends on various controllers distributed throughout the vehicle, which makes the electronic control system in the vehicle extremely important. When the vehicle is powered on, the generator or DCDC (Direct Current to Direct Current) DC converter supplies power to the entire vehicle to ensure that all controllers of the vehicle can maintain their working state; when the vehicle is powered off, the battery provides power to those controllers that require continuous power supply to maintain the operation of basic functions such as anti-theft system, security monitoring, information query, etc.
[0003] However, the premise for all controller functions of the vehicle to be reliably realized is that the power supply is normal. When the power supply of the controller is abnormal, such as the power supply harness is broken, short-circuited, burned, or the DCDC DC converter or battery fails, the controller will not work properly. If a collision occurs during the vehicle driving, resulting in damage to the key harness or controller, it may cause the entire vehicle to stop powering instantly. This makes many functions implemented by the electronic control system unable to be used normally, such as the emergency lights cannot be turned on, which is prone to secondary accidents; and the mechanical parts controlled by electricity or electronic signals cannot be driven, such as the door lock is in a locked state. If the user in the car is injured and fainted, the person outside the car cannot open the door, which will delay the best rescue time. In addition, during the parking of the vehicle, if the battery fails and the whole vehicle loses power, the user cannot unlock the door by NFC (Near Field Communication), Bluetooth or remote control, which not only affects the user's normal use experience, but also may cause the user to be unable to quickly start the vehicle through an external power supply device (such as a jump starter) in an emergency, further increasing safety hazards.

[0027] The following will describe the implementation methods of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.
[0028] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present application in a schematic manner, and therefore the illustrations only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the form, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.
[0029] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.
[0030] First of all, it should be noted that when the vehicle is powered on, the generator or DCDC converter supplies power to the vehicle, which can ensure that all controllers of the vehicle can maintain their working state; and when the vehicle is powered off, the battery provides power to those controllers that require continuous power supply, which can maintain the operation of basic functions such as anti-theft system, security monitoring, information query, etc. However, the inventor of this application has found that when the power supply of the controller is abnormal, such as the power supply harness is broken, short-circuited, burned, or the DCDC converter or battery fails, the controller will not work properly. If a collision occurs during the driving of the vehicle, resulting in damage to the key harness or controller, it may cause the whole vehicle to stop powering instantly. Many functions realized by the electronic control system cannot be used normally, such as the emergency lights cannot be turned on, which is prone to secondary accidents; and mechanical parts that rely on electricity or electronic signals to control cannot be driven, such as the door lock is in a locked state. If the user in the car is injured and faints, the person outside the car cannot open the door, which will delay the best rescue time. In addition, while the vehicle is parked, if the battery fails and the entire vehicle loses power, the user will not be able to unlock the door using NFC, Bluetooth or remote control. This not only affects the user's normal usage experience, but also may cause the user to be unable to quickly start the vehicle through an external power supply in an emergency, further increasing safety hazards.
[0031] Therefore, the present application proposes a vehicle power failure emergency processing system to provide convenience for users after an emergency power failure of the vehicle, and effectively protect the safety of users' lives and property in critical situations.
[0032] See also Figure 1 , Figure 1 FIG. 1 is a block diagram of a vehicle power failure emergency processing system shown in an exemplary embodiment of the present application. Figure 1 As shown, in an exemplary embodiment, the vehicle power failure emergency processing system at least includes a voltage detection module 110, a battery module 120 and a mechanical unlocking module 130, and the voltage detection module 110 is connected to the battery module 120 and the mechanical unlocking module 130, respectively, as described in detail as follows:
[0033] The voltage detection module 110 is connected to the power supply circuit of the vehicle and is used to monitor the working state of the power supply circuit and send a power supply abnormality signal to the battery module and the mechanical unlocking module when the working state is abnormal.
[0034] It should be noted that the vehicle's power supply circuit includes the battery of the vehicle and the DCDC converter, and the battery and the DCDC converter are connected in parallel; the power supply is divided into normal power and K15 power. Normal power refers to the circuit that supplies power normally in the ON gear and continues to supply power in the OFF gear; K15 power refers to the circuit that supplies power normally in the ON gear and stops supplying power in the OFF gear.
[0035] See also Figure 2 , Figure 2 FIG. 1 is a schematic diagram of a vehicle power distribution system according to an exemplary embodiment of the present application. Figure 2 As shown in the figure, it mainly includes DCDC converter, battery and various power loads. The DCDC converter is responsible for converting the output voltage of the high-voltage battery into low-voltage electricity to supply the cockpit controller, air conditioning compressor, laser radar and other equipment. These equipment usually require a lower operating voltage and consume a large current; the battery directly supplies power to the door controller, emergency module, airbag and some other equipment. These equipment usually require a stable operating voltage and can start quickly in some special cases (such as a vehicle collision) to protect the safety of the driver and passengers.
[0036] In this embodiment, the vehicle power failure emergency processing system is connected to the normal power supply as an emergency module. When the power supply of the entire vehicle stops abnormally, the system detects the power failure and starts to enter the working state.
[0037] The battery module 120 is used to supply power to the electrical loads in the vehicle in response to the power supply abnormality signal, so as to maintain the normal operation of the electrical loads after the vehicle loses power.
[0038] In this embodiment, the vehicle power failure emergency handling system is connected to the normal power supply as an emergency module, and the battery module 120 is used to power the power loads in the vehicle, which need normal power supply when in the ON position and need continuous power supply in the OFF position, such as door controllers, airbags, and emergency lights.
[0039] The mechanical unlocking module 130 is used to open the locking device of the mechanical components in the vehicle in response to the power supply abnormality signal, so as to realize normal unlocking of the mechanical components after the vehicle loses power.
[0040] It should be noted that the use of the mechanical unlocking module 130 is independent of the battery module 120 , that is, after the vehicle loses power, the battery module 120 is not needed for power supply.
[0041] It should also be noted that, in a possible embodiment, the mechanical unlocking module 130 is used to open the locking devices of mechanical components in the vehicle by means of a mechanical unlocking method. When the vehicle is powered normally, these locking devices can be automatically opened by means of power supply. Therefore, when the battery module 120 starts to supply power, it can also supply power to the controllers of these locking devices so that these locking devices can be automatically unlocked.
[0042] For example, when the vehicle is powered normally, the door control can control the door to open automatically. After the vehicle loses power, the locking device of the door can be mechanically unlocked through the mechanical unlocking module 130, or it can be automatically unlocked through the power supply of the battery module 120, such as by NFC, Bluetooth or remote control.
[0043] In this way, through the design of the vehicle power failure emergency handling system, when the vehicle power supply is normal, the system function is in failure mode, and when the vehicle power supply is abnormal, the system function starts to work, that is, when the vehicle power supply is abnormal, the power supply function and unlocking function are activated and start working. After the vehicle power failure in an emergency, it can meet the needs of power supply to power loads and emergency unlocking, provides convenience for users, and can effectively protect the safety of users' lives and property in critical situations.
[0044] In this embodiment, the vehicle power failure emergency handling system is mainly divided into two parts. One part is the battery module 120. When an abnormal power supply to the vehicle is detected, the battery module 120 enters a normal working state. The other part is the mechanical unlocking module 130. When an abnormal power supply to the vehicle is detected, the mechanical unlocking device 130 enters a usable state.
[0045] Specifically, the battery module 120 includes at least a backup battery circuit, which includes at least: a backup battery for powering the voltage detection module 110 and the backup battery circuit; a drive circuit connected to the voltage detection module 110, for receiving and responding to power supply abnormality signals, switching the backup battery circuit to an on state, so that the power load set on the backup battery circuit is in a connected state with the backup battery.
[0046] In this embodiment, the battery module 120 adopts a backup battery circuit, which is powered by the backup battery therein, and the backup battery can also power the voltage detection module 110, so that the voltage detection module 110 can detect the power supply status of the vehicle after the vehicle loses power and determine whether the power supply of the main circuit of the vehicle is normal.
[0047] See also Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a backup battery circuit shown in an exemplary embodiment of the present application. Figure 3 As shown, in this embodiment, the drive circuit is connected to the voltage detection module 110. When the voltage detection module 110 detects that the power supply circuit is normal, the drive circuit is in a disconnected state and does not work. When the voltage detection module 110 detects that the power supply circuit is abnormal and stops supplying power, the drive circuit is in a connected state and works, so that the power loads set on the backup battery circuit are connected to the backup battery, and the normal power supply of these power loads is achieved after the vehicle is powered off in an emergency. In addition, the ground wire runs through the entire circuit to ensure the safety and reliability of the battery module 110 in a grounding manner.
[0048] As a possible embodiment, the backup battery adopts a solar cell and is designed to be located in a position of the vehicle that is easy to replace.
[0049] In one embodiment, the battery module also includes a backup battery detection unit, which includes at least: a voltage sensor for monitoring the voltage of the backup battery and feeding back the voltage to the alarm subunit; a temperature sensor for monitoring the temperature of the backup battery and feeding back the voltage to the alarm subunit; an alarm subunit for evaluating the battery status of the backup battery based on the voltage and temperature, and triggering an alarm when the battery status is abnormal.
[0050] In this embodiment, a backup battery detection unit is added, such as a backup battery status detection circuit, to promptly give an alarm when the backup battery fails, so as to enhance the reliability of the backup battery after the vehicle loses power.
[0051] In one embodiment, the electrical load includes an emergency lighting device, which is arranged on a backup battery circuit and is powered by the backup battery when the vehicle loses power.
[0052] In this embodiment, after the vehicle loses power in an emergency, the battery module 120 can power the emergency lighting device. Especially in the event of a vehicle collision, failure, etc., after the vehicle loses power, the emergency lighting device can still realize a temporary lighting function to provide necessary lighting for the occupants of the vehicle, or alert other road users to dangerous situations, thereby effectively improving the safety of the vehicle.
[0053] Specifically, the mechanical unlocking module 130 includes at least a mechanical handle, a mechanical pull wire and a lock for limiting the sliding of the mechanical pull wire; the mechanical pull wire is connected to the locking device and is connected to the mechanical handle through the lock; the lock is used to receive and respond to power supply abnormality signals, switch from a locked state to an unlocked state, so that the locking device can be opened by pulling the mechanical pull wire through the mechanical handle.
[0054] In this embodiment, the mechanical unlocking module 130 includes a mechanical handle, a mechanical pull wire and a lock that limits the sliding of the mechanical pull wire, wherein the mechanical pull wire is connected to the locking device and is connected to the mechanical handle through the lock. After the vehicle loses power in an emergency, the lock switches from a locked state to an unlocked state. At this time, the locking device can be opened by pulling the mechanical pull wire through the mechanical handle, thereby unlocking the mechanical components.
[0055] In one embodiment, the locker is an electromagnetic locker, which includes an electromagnetic coil, an iron core and a rebound mechanism. The mechanical pull wire passes through the iron core, and the electromagnetic coil is connected to the power supply circuit. When the working state of the power supply circuit is normal, a magnetic field is generated, and the iron core is sucked into the coil slot based on the magnetic field to limit the sliding of the mechanical pull wire. When the power supply circuit is in an abnormal state, the magnetic field disappears, and the iron core is ejected from the coil slot based on the rebound mechanism, restored to its original position, and the mechanical pull wire is released.
[0056] In this embodiment, by utilizing the characteristics that the electromagnetic coil generates a magnetic field when energized and the magnetic field disappears when the power is cut off, an electromagnetic lock is used in combination with a mechanical handle and a mechanical pull wire to achieve the purpose of the mechanical unlocking module 130 being able to unlock the locking device of the mechanical device after an emergency power outage of the vehicle.
[0057] In one embodiment, the mechanical device includes a vehicle door, the locking device includes a door lock locking device, the mechanical unlocking module includes a door mechanical unlocking sub-module, the mechanical lock sub-module includes an outside vehicle mechanical handle, a door mechanical pull wire and a door lock that limits the sliding of the door mechanical pull wire; the door mechanical pull wire is connected to the door lock locking device and is connected to the outside vehicle mechanical handle through the door lock; the door lock is used to receive and respond to a power supply abnormality signal, switching from a locked state to an unlocked state, so as to open the door lock locking device by pulling the door mechanical pull wire through the outside vehicle mechanical handle.
[0058] In this embodiment, the mechanical device includes a vehicle door, the locking device includes a door lock locking device, and the mechanical unlocking module includes a vehicle door mechanical unlocking sub-module. The vehicle door mechanical unlocking sub-module is integrated with an outside mechanical handle, a door mechanical pull wire, and a door lock that limits the sliding of the door mechanical pull wire. The door lock can be an electromagnetic lock. After the vehicle loses power in an emergency, the door can be opened outside the vehicle through the door mechanical handle through the design of the door mechanical unlocking sub-module, thereby ensuring the safety of people in the vehicle in an emergency.
[0059] See also Figure 4 , Figure 4 FIG. 1 is a schematic diagram of a vehicle door mechanical unlocking mechanism according to an exemplary embodiment of the present application. Figure 4As shown, the vehicle door mechanical unlocking mechanism (i.e., the vehicle door mechanical unlocking submodule) includes an external mechanical handle, a vehicle door mechanical pull wire and a vehicle door locker for limiting the sliding of the vehicle door mechanical pull wire. The vehicle door mechanical pull wire is connected to the door lock locking device and is connected to the vehicle external mechanical handle through the vehicle door locker. The vehicle door locker includes an electromagnetic locker, including an electromagnetic coil, an iron core and a rebound mechanism. The vehicle door mechanical pull wire passes through the iron core. The electromagnetic coil is connected to the power supply circuit. When the working state of the power supply circuit is normal, a magnetic field is generated. Based on the magnetic field, the iron core is sucked into the coil card slot to limit the sliding of the vehicle door mechanical pull wire. At this time, the vehicle door cannot be opened by the external mechanical handle, thereby avoiding the anti-theft problem of the vehicle. When the power supply circuit is in an abnormal state, the magnetic field disappears, and based on the rebound mechanism, the iron core is ejected from the coil card slot to return to its original position, thereby releasing the vehicle door mechanical pull wire. At this time, the vehicle door can be opened by the external mechanical handle, thereby solving the problem that the vehicle door cannot be opened in case of emergency power failure.
[0060] The vehicle door mechanical unlocking mechanism does not use a backup battery for power supply, but adopts a mechanical device and an electromagnetic coil to realize the external mechanical unlocking of the vehicle door when the vehicle power fails and the door cannot be opened.
[0061] It should also be noted that in addition to the door locks, other mechanical components in the vehicle that rely on electricity or electronic signals to control the opening and closing, such as the electric tailgate, electric windows and electric sunroof, can be designed with corresponding mechanical unlocking modules so that they can be opened normally after an emergency power outage in the vehicle, thereby ensuring the safety or operability of these devices in the event of a power failure.
[0062] The above-mentioned vehicle power failure emergency processing system integrates a voltage detection module, a battery module and a mechanical unlocking module, wherein the voltage detection module is connected to the vehicle's power supply circuit to monitor the working state of the power supply circuit, and sends a power supply abnormality signal to the battery module and the mechanical unlocking module when the working state is abnormal. The battery module is used to respond to the power supply abnormality signal to supply power to the electrical load in the vehicle so that the electrical load can be used normally. The mechanical unlocking module is used to respond to the power supply abnormality signal to open the locking device of the mechanical device in the vehicle so that the mechanical device can be opened normally when the power failure cannot be opened. Contrary to the logic of the vehicle controller supplying power and stopping work when the power is cut off, the power supply function and the unlocking function are activated and start working when the vehicle power supply is abnormal, so as to meet the scene requirements of power supply to the electrical load and emergency unlocking after the vehicle loses power in an emergency, providing convenience for users and effectively protecting the safety of users' lives and property in critical situations.
[0063] See also Figure 5 , Figure 5 FIG. 1 is a flow chart of a method for emergency handling of a vehicle power failure, shown in an exemplary embodiment of the present application. Figure 5As shown, in an exemplary embodiment, the method uses the vehicle power failure emergency handling system as described above, and at least includes steps S510 to S530, which are described in detail as follows:
[0064] Step S510, monitoring the working state of the power supply circuit in the vehicle through a voltage detection module, where the working state includes a normal state and an abnormal state;
[0065] Step S520, when the working state is an abnormal state, activating the power supply function of the battery module and the unlocking function of the mechanical unlocking module;
[0066] Step S530: supplying power to electrical loads in the vehicle based on the power supply function, and unlocking a locking device of a mechanical component in the vehicle based on the unlocking function.
[0067] It should be noted that the vehicle power failure emergency processing method provided in the above embodiment and the vehicle power failure emergency processing system provided in the above embodiment belong to the same concept, and the content of each step has been described in detail in the system embodiment and will not be repeated here.
[0068] See also Figure 6 , Figure 6 FIG. 1 is a flowchart of a specific method for emergency handling of vehicle power failure, shown in an exemplary embodiment of the present application. Figure 6 As shown, the specific vehicle power failure emergency handling method is aimed at emergency lights and door unlocking, including: first checking the vehicle power supply status to determine whether the vehicle is in a normal power supply state; if the power supply is normal and all controllers are working normally, the emergency lights will turn on normally and the doors will unlock normally. If the power supply is stopped, it will be determined whether the system supports the emergency design; if the emergency design is not supported, all controllers will stop working, the emergency lights cannot be used, and the door cannot be unlocked from the outside. If the emergency design is supported, after the emergency mode is activated, the backup battery starts to supply power, so that the emergency lights can be turned on and the backup mechanical device is activated, so that the door can be unlocked from the outside.
