Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a vehicle control method, device, equipment and storage medium. Background Art

[0002] When a vehicle collides while driving, the airbags and other restraint systems in the vehicle will protect the occupants from severe impacts and collisions, and avoid injuries from secondary collisions.

[0003] In the related art, it is generally determined whether a vehicle has collided through the acceleration signal during the collision process. However, the acceleration sensors are generally located on both sides of the front of the vehicle. When a side collision such as a collision with a door occurs, the acceleration generated is relatively weak compared to a frontal collision. Therefore, it takes a longer time to capture the signal, and the acceleration signal cannot be quickly transmitted to the vehicle controller, resulting in the vehicle controller often detonating the airbag too late, threatening the safety of the occupants in the vehicle.

[0057] In order to make the technical solutions and advantages of the present application clearer, the implementation methods of the present application are described in further detail below.

[0058] The terms "first", "second", "third" and "fourth" etc. in the specification and claims of the present application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0059] It should be noted that the information (including but not limited to user device information, user personal information, etc.), data (including but not limited to data used for analysis, stored data, displayed data, etc.) and signals involved in this application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions. For example, the status information and location information involved in this application are all obtained with full authorization.

[0060] Please refer to Figure 1, which shows a schematic diagram of the implementation environment of the vehicle control method shown in an exemplary embodiment of the present application; the implementation environment includes: a vehicle controller 10, a capacitive sensor 20, an acceleration sensor 30, a pressure sensor 40, an airbag controller 50, a door controller 60, a seat belt controller 70, a power supply controller 80 and a power source controller 90. The vehicle controller 10 obtains the capacitance value, the acceleration value and the pressure value through the capacitive sensor 20, the acceleration sensor 30 and the pressure sensor 40 respectively. When the vehicle controller 10 determines that the vehicle has collided and the degree of collision is relatively serious based on the capacitance value, the acceleration value and the pressure value, it sends an instruction to at least one of the above controllers to control the vehicle to perform anti-collision measures. This process is described in detail in subsequent embodiments. The vehicle in the embodiment of the present application can be a new energy vehicle or a fuel vehicle; the new energy vehicle includes a pure electric vehicle or a hybrid vehicle.

[0061] Please refer to Figure 2 , which shows a flow chart of a vehicle control method shown in an exemplary embodiment of the present application. Figure 2 , the method comprises the following steps.

[0062] Step 201, the vehicle controller obtains real-time status information of the vehicle, the status information at least includes the capacitance value of each door, the insulation arrangement between the inner door panel and the outer door panel of each door forms a capacitor, and the capacitance value is detected by a capacitance sensor electrically connected to the inner door panel and the outer door panel respectively.

[0063] In the embodiment of the present application, the state information is used to detect whether the vehicle has collided. The real-time state information of the vehicle can be the state information of the vehicle during driving, or the state information of the vehicle during non-driving, that is, the method provided in the embodiment of the present application can detect whether the vehicle has collided during driving, or detect whether the vehicle has collided during non-driving.

[0064] In the embodiment of the present application, the door inner panel and the door outer panel of each door are insulated to form a capacitor, that is, for each door, the door inner panel and the door outer panel serve as the positive electrode and the negative electrode of the capacitor respectively. For example, if the door inner panel serves as the positive electrode of the capacitor, the door outer panel serves as the negative electrode of the capacitor; or if the door inner panel serves as the negative electrode of the capacitor, the door outer panel serves as the positive electrode of the capacitor.

[0065] It should be noted that a capacitor is mainly composed of two conductors that are insulated from each other and close to each other. These two conductors are also the two electrodes of the capacitor, which can be metal plates. The material separating the two electrodes is a dielectric, which can be an insulating material such as air, paper, polyethylene, etc. The properties of the dielectric, such as the dielectric constant, will affect the capacitance value. When a voltage is applied between the two electrodes, an electric field will be formed between the plates of the two electrodes. Charges will accumulate on the plates under the action of the electric field, forming a charge storage. The capacitor can be charged by a DC power supply, at which time the charge will accumulate between the two plates to form an electric field. When the power supply is disconnected, the capacitor neutralizes the charge by discharging. The charge on the capacitor can be changed by changing the area of ​​the two plates or the distance between the two plates. For example, if the distance between the two plates is reduced, the charge will increase, resulting in an increase in the capacitance value. When the car door is hit, it will deform, resulting in a decrease in the distance between the inner door panel and the outer door panel, so the capacitance value of the car door will increase.

[0066] The capacitance value is detected by a capacitance sensor electrically connected to the inner door panel and the outer door panel respectively, and the capacitance sensor is connected to the vehicle controller so that the vehicle controller obtains the capacitance value of the door.

[0067] For example, see Figure 3 , Figure 3 is a schematic diagram showing the deformation of a vehicle door according to an exemplary embodiment. In which, before the collision, the distance between the vehicle door outer panel and the vehicle door inner panel is large; after the collision, the distance between the vehicle door outer panel and the vehicle door inner panel decreases, thereby causing the capacitance value of the vehicle door to increase.

[0068] Step 202: If the capacitance value of at least one door of the vehicle reaches a capacitance threshold, the vehicle controller controls the vehicle to perform anti-collision measures.

[0069] In the embodiment of the present application, the capacitance threshold is used to define the severity of the vehicle collision, that is, when the capacitance value reaches the capacitance threshold, it indicates that the collision is serious and anti-collision measures need to be taken. When the capacitance value does not reach the capacitance threshold, it indicates that no collision has occurred or the collision is not serious and no anti-collision measures need to be taken.

[0070] In an embodiment of the present application, when a door of a vehicle collides, the distance between the inner door panel and the outer door panel decreases, which in turn causes the capacitance value to increase, so the capacitance value of the door may reach the capacitance threshold. When the capacitance value of the door reaches the capacitance threshold, it indicates that the degree of collision of the door is serious, so anti-collision measures are performed. When the capacitance value of the door does not reach the capacitance threshold, it indicates that the degree of collision of the door is not serious, so anti-collision measures may not be performed. Since each door of the vehicle may collide, when any door collides and the degree of collision of the door is judged to be serious based on the capacitance value, the vehicle is controlled to perform anti-collision measures.

[0071] In an embodiment of the present application, a vehicle controller controls the vehicle to perform anti-collision measures, including at least one of the following implementation methods.

[0072] (1) Detonate the vehicle's airbag.

[0073] In some embodiments, airbags are arranged at multiple locations in the vehicle, and detonating the airbags in the vehicle means detonating all the airbags in the vehicle.

[0074] In other embodiments, the vehicle controller also obtains the position information of the occupant in the vehicle. Accordingly, detonating the airbag in the vehicle means detonating the airbag in the vehicle corresponding to the position information. The airbag corresponding to the position information is also the airbag around the position of the occupant. For example, if the occupant is in the main driving seat, the airbags include at least the airbag in front of the main driving seat and the airbag on the side of the door of the main driving seat.

[0075] It should be noted that if the vehicle controller fails to obtain the position information, it means that there is no occupant in the vehicle, and the airbag in the vehicle will not be deployed. Optionally, the vehicle controller obtains the position information of the occupant in the vehicle through a camera, an infrared sensor, etc.

[0076] In the embodiment of the present application, by detonating the airbag, a buffer is formed between the occupant and the vehicle to protect the occupant from direct impact. Detonating only the airbags around the occupant position can, on the one hand, avoid interference with the safety of the occupant caused by airbags in other positions in the vehicle, and on the other hand, avoid wasting the airbags in the vehicle.

[0077] In some embodiments, the vehicle controller also obtains the physical characteristics of the occupants in the vehicle, such as height and weight, and determines the inflation coefficient of the airbag based on the physical characteristics. The inflation coefficient is used to indicate the inflation degree of the airbag, thereby matching the inflation degree of the airbag with the physical characteristics of the occupants, minimizing the injuries to the occupants, and optimizing the restraint on the occupants. Among them, the inflation degree of the airbag is positively correlated with the height and weight of the occupants, that is, the greater the height and weight, the greater the inflation degree of the airbag, so as to reduce the impact force on the occupants in the event of a collision.

[0078] In some embodiments, the airbag in the vehicle is controlled by an airbag controller of the vehicle. The vehicle controller is connected to the airbag controller. The vehicle controller sends a first instruction to the airbag controller, and the first instruction is used to instruct the airbag controller to detonate the airbag in the vehicle.

[0079] (2) Unlock the vehicle doors.

[0080] Among them, unlocking the vehicle doors refers to unlocking all the vehicle doors, and unlocking the doors facilitates the escape of passengers in the vehicle.

[0081] In some embodiments, the vehicle door is controlled by a vehicle door controller. The vehicle controller sends a second instruction to the vehicle door controller, and the second instruction is used to instruct the vehicle controller to unlock the vehicle door.

[0082] (3) Tighten the vehicle's seat belts.

[0083] In some embodiments, the seat belt is controlled by a seat belt controller. The vehicle controller is connected to the seat belt controller. The vehicle controller sends a third instruction to the seat belt controller, and the third instruction is used to instruct the seat belt controller to tighten the seat belt.

[0084] In some embodiments, the vehicle controller also obtains the position information of the occupant in the vehicle. Accordingly, tightening the vehicle's seat belt means tightening the seat belt on the seat corresponding to the position information. It should be noted that if the vehicle controller fails to obtain the position information, it means that there is no occupant in the vehicle, and the vehicle's seat belt is not tightened.

[0085] In the embodiment of the present application, by tightening the seat belt, the occupant is fixed in the seat, reducing the risk of forward collision due to inertia and reducing the possibility of injury to the occupant. By only tightening the seat belt of the seat where the occupant is located, interference with the safety of the occupant caused by irrelevant seat belts is avoided, and since there is no need to tighten each seat belt, it is also conducive to improving the efficiency of tightening the seat belt.

[0086] In some embodiments, the vehicle controller also obtains physical characteristics of the occupants in the vehicle, such as height and weight, and determines the tightening factor of the occupants' seat belts based on the physical characteristics. The tightening factor is used to indicate the tightening degree of the seat belts, thereby matching the tightening degree of the seat belts with the physical characteristics of the occupants, so that the seat belts provide better personalized protection for the occupants.

[0087] (4) Cut off the power supply to the vehicle.

[0088] In some embodiments, the power supply is controlled by a power supply controller. The vehicle controller is connected to the power supply controller. The vehicle controller sends a fourth instruction to the power supply controller, and the fourth instruction is used to instruct the power supply controller to cut off the power supply.

[0089] In the embodiment of the present application, by cutting off the power supply of the vehicle, a power short circuit is avoided and the risk of fire is reduced.

[0090] (5) Cut off the vehicle’s power source.

[0091] The vehicle in the embodiment of the present application can be a new energy vehicle or a fuel vehicle, and the new energy vehicle includes a pure electric vehicle or a hybrid vehicle. Therefore, if the vehicle is a fuel vehicle, cutting off the power source means cutting off the fuel supply. If the vehicle is a pure electric vehicle, cutting off the power source means cutting off the power supply. If the vehicle is a hybrid vehicle, cutting off the power source means cutting off the supply of fuel and power.

[0092] In some embodiments, the power source is controlled by a power source controller. If the vehicle is a fuel vehicle, the power source controller is also an engine controller. If the vehicle is a pure electric vehicle, the power source controller is a power source controller. If the vehicle is a hybrid vehicle, the power source controller includes an engine controller and a power source controller.

[0093] The vehicle controller sends a fifth instruction to the power source controller, and the fifth instruction is used to instruct the power source controller to cut off the power source.

[0094] In the embodiment of the present application, by cutting off the power source, fuel leakage or power short circuit is prevented, thereby reducing the risk of fire.

[0095] (6) Control the vehicle to send out a rescue signal.

[0096] In some embodiments, the vehicle controller controls the networked host of the vehicle to send a rescue signal to the rescue platform. Optionally, the vehicle controller sends a sixth instruction to the networked host, and the sixth instruction is used to instruct the networked host to send a rescue signal to the rescue platform.

[0097] In some embodiments, the vehicle controller can also control the vehicle to emit audible and visual alarms.

[0098] In the embodiment of the present application, the vehicle is controlled to send out a rescue signal so that the occupants can be rescued in time.

[0099] In the embodiment of the present application, the process of controlling the vehicle to perform anti-collision measures if the state information meets the preset conditions is realized through the above step 202. In this embodiment, each door of the vehicle has the possibility of collision. Therefore, when the capacitance value of any door reaches the capacitance threshold, it is determined that the vehicle has collided and the capacitance value indicates that the degree of collision is large. At this time, anti-collision measures are performed to provide reliable safety protection for the occupants of the vehicle. Since the inner door panel and the outer door panel of the door form a capacitor, when the door collides, the capacitance value of the door changes immediately, and the capacitance sensor is connected to the inner door panel and the outer door panel respectively, and the changed capacitance can be obtained immediately, and then the capacitance value can be transmitted to the vehicle controller in time, so that the vehicle controller can perform anti-collision measures in time, improve timeliness, and further improve the safety protection for the occupants.

[0100] In some embodiments, when a collision occurs, the vehicle controller also adjusts the position of the seat, that is, if the capacitance value of at least one door of the vehicle reaches a capacitance threshold, the distance between the target seat and the target door is adjusted to make the target seat away from the target door. The target door is the door whose capacitance value reaches the capacitance threshold, and the target seat is the seat adjacent to the target door and where the occupant is located.

[0101] The vehicle controller also obtains the position information of the occupants in the vehicle to determine whether there are occupants in the target seat. In this embodiment, if the capacitance value of the target door reaches the capacitance threshold, it means that the target door has been hit and the collision degree is large, and then the seat adjacent to the door is adjusted away from the door to avoid collision damage to the occupants in the seat caused by excessive deformation of the door, thereby further ensuring the safety of the occupants.

[0102] In the embodiment of the present application, when the capacitance value of any door reaches the capacitance threshold, the above anti-collision measures are executed. In other embodiments, the vehicle's collision condition is also determined in combination with the acceleration value and the pressure value of the vehicle to determine whether anti-collision measures are taken. The process is shown in the following steps.

[0103] Step 203: If the capacitance value of at least one door of the vehicle reaches a capacitance threshold and at least one of the acceleration value and the pressure value included in the status information reaches a respective preset threshold, the vehicle controller controls the vehicle to perform anti-collision measures.

[0104] In an embodiment of the present application, the real-time status information of the vehicle also includes the acceleration value and pressure value of the vehicle.

[0105] Among them, the acceleration value of the vehicle is also the acceleration of the vehicle's movement. When the vehicle is hit by a front or rear collision or a side collision, the vehicle will instantly generate a large acceleration, that is, the acceleration value of the vehicle will change. The pressure value of the vehicle includes the pressure value of each door of the vehicle. The pressure value of the door refers to the pressure value between the inner door panel and the outer door panel. When the door is hit, the pressure value will change due to the deformation of the door. The acceleration value is detected by the acceleration sensor. The pressure value is detected by the pressure sensor.

[0106] The capacitance value of at least one door of the vehicle reaches the capacitance threshold and at least one of the acceleration value and the pressure value reaches the respective preset thresholds, that is, the capacitance value of at least one door reaches the capacitance threshold and the acceleration value of the vehicle reaches the acceleration threshold, or the capacitance value of at least one door reaches the capacitance threshold and the pressure value of the vehicle reaches the pressure threshold, or the capacitance of at least one door reaches the capacitance threshold, the acceleration value of the vehicle reaches the acceleration threshold, and the pressure value of the vehicle reaches the pressure threshold.

[0107] In an embodiment of the present application, since each vehicle door corresponds to a pressure value, the capacitance value of at least one vehicle door reaches the capacitance threshold and the pressure value of the vehicle reaches the pressure threshold, which means that the capacitance value of the same vehicle door reaches the capacitance threshold and the pressure value reaches the pressure threshold, so as to further improve the accuracy of collision judgment.

[0108] In some embodiments, the state information also includes a force value of the vehicle. Optionally, if the capacitance value of at least one door reaches a capacitance threshold and the force value of the vehicle reaches a force threshold, the vehicle controller controls the vehicle to perform anti-collision measures.

[0109] The force value of the vehicle may refer to the force value of the entire vehicle or the force value of each door of the vehicle. Optionally, the capacitance value of at least one door reaches the capacitance threshold and the force value of the vehicle reaches the force threshold means that the capacitance value of the same door reaches the capacitance threshold and the force value reaches the force threshold, so as to further improve the accuracy of collision judgment.

[0110] In this embodiment, since the vehicle is hit, the force value of the vehicle will increase instantaneously. Therefore, whether the vehicle is hit is also determined by the force value of the vehicle, which further ensures the accuracy of the collision judgment.

[0111] It should be noted that if the collision situation is comprehensively judged based on capacitance value, acceleration value and pressure value, the vehicle controller obtains the acceleration value and pressure value at the same time as the capacitance value, so as to improve the timeliness of data acquisition, facilitate fast and efficient collision judgment, and then quickly implement anti-collision measures.

[0112] The process of the vehicle controller controlling the vehicle to execute the anti-collision measures in step 203 is the same as the process of the vehicle controller executing the anti-collision measures in step 202, which will not be repeated here. In this embodiment, the capacitance value is combined with the acceleration value and the pressure value to jointly judge the collision situation of the vehicle. In this way, more elements are combined for judgment, which can further improve the accuracy of the judgment.

[0113] Step 204: If the capacitance value of each door of the vehicle does not reach the capacitance threshold and the acceleration value and the pressure value in the status information reach their respective preset thresholds, the vehicle controller controls the vehicle to perform collision measures.

[0114] Wherein, the acceleration value and the pressure value both reaching their respective preset thresholds means that the acceleration reaches the acceleration threshold and the pressure value reaches the pressure threshold. The vehicle as a whole has an acceleration value, and each door has a corresponding pressure value, then the acceleration value and the pressure value both reaching their respective preset thresholds further means that the acceleration value of the vehicle reaches the acceleration threshold and the pressure value of at least one door reaches the pressure threshold.

[0115] In some embodiments, when a collision occurs, the vehicle controller also adjusts the position of the seat, that is, if the pressure value of at least one door of the vehicle reaches a pressure threshold, the distance between the first seat and the first door is adjusted to make the first seat away from the first door. The first door is the door whose pressure value reaches the pressure threshold, and the first seat is the seat adjacent to the first door and where the occupant is located.

[0116] The vehicle controller also obtains the position information of the occupants in the vehicle to determine whether there is an occupant in the first seat. In this embodiment, the pressure value of the first door reaches the pressure threshold, indicating that the first door has been hit and the degree of the collision is relatively serious, and then the seat adjacent to the door is adjusted away from the door to avoid collision damage to the occupant in the seat caused by excessive deformation of the door, thereby further ensuring the safety of the occupant.

[0117] In the embodiment of the present application, the capacitance value of each door does not reach the capacitance threshold, which may be due to a failure of the capacitance sensor. In this case, the acceleration value and the pressure value are detected, and if both the acceleration value and the pressure value reach their respective preset thresholds, it can also indicate that the vehicle has collided, thereby improving the comprehensiveness and accuracy of vehicle collision detection, and then executing anti-collision measures to effectively protect the occupants in the vehicle.

[0118] In some embodiments, the acceleration value and the pressure value are obtained only when the capacitance value of each door of the vehicle has not reached the capacitance threshold value, so as to avoid data acquisition waste. In other embodiments, the acceleration value and the pressure value are obtained at the same time as the capacitance value, so that when the collision cannot be determined based on the capacitance value, an instant judgment can be made based on the acceleration value and the pressure value, thereby improving timeliness.

[0119] It should be noted that the serial numbers of the above steps 202-204 are only for convenience of explanation and are not used to limit the execution order of the three steps. The three steps are all optional implementation steps.

[0120] An embodiment of the present application provides a vehicle control method, which obtains real-time status information of the vehicle, and the status information includes at least the capacitance value of each door of the vehicle. Since a capacitor is formed due to the insulation between the inner door panel and the outer door panel of the vehicle door, when any door of the vehicle collides, the distance between the inner door panel and the outer door panel is reduced, which will cause the capacitance value to increase. The capacitance sensor is electrically connected to the inner door panel and the outer door panel, respectively, so that the capacitance value can be quickly and sensitively obtained. On this basis, the capacitance value can be quickly transmitted to the vehicle controller, thereby improving data acquisition efficiency. When the status information meets the preset conditions, the vehicle controller can promptly control the vehicle to execute anti-collision measures, thereby improving timeliness and thus improving the safety of the vehicle.
