[0045] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0047] In a first aspect, an embodiment of the present application provides a vehicle safety control method.

[0048] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the vehicle safety control method of this application. Figure 1 As shown, the vehicle safety control method includes:

[0049] Step S10: When a target battery fire is detected, the vehicle door is unlocked to keep the target person away.

[0050] For example, in this embodiment, the target individuals are the vehicle's passengers and driver. When a battery fire is detected, the system promptly identifies the fire source and triggers an alarm. This automatically activates the door unlocking mechanism, ensuring the doors are unlocked, allowing the vehicle's passengers and driver to quickly evacuate the target vehicle. Once the doors are unlocked, the target individuals are safely guided away from the vehicle to avoid being trapped. This automated response minimizes the risk of injury to the target individuals from a battery fire and provides an effective escape route.

[0051] Step S20: Determine the destination location based on a preset path planning algorithm, where the destination location is an open area, an uninhabited area, or an area where fire can be extinguished.

[0052] For example, in an embodiment of the present application, the destination location is an open area, an uninhabited area or a fire-extinguishable area, wherein an open area refers to an open space without obstacles or personnel, which can effectively prevent the spread of fire; an uninhabited area refers to an area without personnel, which can ensure that the risk of personal injury is reduced in an emergency; a fire-extinguishable area is an area with fire-fighting facilities or capable of effective fire extinguishing; the preset path planning algorithm can be determined according to actual needs and is not limited here. For example, the path planning algorithm in the embodiment of the present application is to determine the destination location with small traffic volume and closest to the target vehicle. It should be understood that the principle of the path planning algorithm is common knowledge in this field and will not be repeated here for the sake of brevity of description.

[0053] Specifically, the path planning algorithm comprehensively considers factors such as road conditions, environmental safety (such as traffic volume), and distance to calculate the optimal escape route and the best destination location. This destination location is usually an open area, an unoccupied area, or a fire-extinguishable area. The goal is to maximize the safety of surrounding personnel and ensure that the target vehicle can quickly reach the destination location. In this way, the path planning algorithm can achieve automated and effective escape in fire or other emergency situations, ensuring that the target vehicle avoids dangerous areas in a timely and safe manner.

[0054] Step S30: Control the target vehicle to leave the target battery after reaching the destination position.

[0055] For example, in an embodiment of the present application, after determining the destination location, the target vehicle is controlled to travel from the location where the battery fire occurred to the destination location along the optimal escape route, avoiding possible obstacles and dangerous areas to ensure safety; after the vehicle arrives at the destination, the system can activate the target battery's ejection mechanism to separate the target battery from the target vehicle to quickly isolate the burning battery, prevent the fire from spreading, ensure the safety of other vehicles or the surrounding environment, and facilitate subsequent emergency response.

[0056] Step S40: Determine the target initial kinetic energy of the target vehicle based on the mass of the target vehicle and the speed of the target vehicle when it leaves the target battery.

[0057] For example, in the embodiment of the present application, the target vehicle mass and the speed of the target vehicle when leaving the target battery are substituted into the following calculation formula to obtain the target initial kinetic energy of the target vehicle. The calculation formula is as follows:

[0058]

[0059] Where, m is the target vehicle mass; v is the speed of the target vehicle when it leaves the target battery; E is the target initial kinetic energy of the target vehicle.

[0060] Step S50: Controlling the target vehicle to travel from the destination location to another location based on the target initial kinetic energy.

[0061] For example, in the embodiment of the present application, the other locations are safe locations away from the target battery, and their specific settings can be determined according to actual needs and are not limited here; after the target battery is thrown away, the initial kinetic energy of the target vehicle becomes a key factor for it to continue moving and reach other locations; specifically, the initial kinetic energy of the target vehicle determines its starting speed and provides a basis for subsequent inertial motion. Based on the target initial kinetic energy and inertial motion, the target vehicle can travel from the destination location to other locations without the support of additional power, thereby reducing further damage to the battery after fire and explosion, and thus buying time for taking safety measures.

[0062] This application controls the unlocking of the vehicle door to quickly release the target person when a target battery fire is detected, thereby avoiding harm to the person caused by the fire; determines a destination location of an open area, an uninhabited area or a fire-extinguishable area based on a preset path planning algorithm, thereby reducing the risk of fire spread and reducing the threat to the surrounding environment; after arriving at the destination location, the system controls the target vehicle to throw the burning battery away from the vehicle body, thereby reducing the possibility of the fire spreading to other components; determines the target initial kinetic energy of the target vehicle based on the mass of the target vehicle and the corresponding speed of the target vehicle when it throws away the target battery; further controls the target vehicle to travel from the destination location to other locations through the target initial kinetic energy, ensuring that the target vehicle is away from the fire source or dangerous area, thereby effectively reducing the hazards caused by the battery fire and ensuring the safety of the target vehicle and the surrounding environment.

[0063] Furthermore, in one embodiment, referring to Figure 2 As shown, before the step of detecting that the target battery is on fire, the method further includes:

[0064] Step P10: If any one of the following conditions is detected: the smoke concentration is greater than a preset concentration threshold, the temperature is greater than a preset temperature threshold, or the infrared radiation intensity is greater than a preset intensity threshold, it is determined that the target battery is on fire;

[0065] Step P20: If the smoke concentration is greater than the preset concentration threshold, the temperature is greater than the preset temperature threshold, and the infrared radiation intensity is greater than the preset intensity threshold, it is determined that the target battery is not on fire.

[0066] For example, in the embodiments of the present application, the specific values ​​of the preset concentration threshold, preset temperature threshold, and preset intensity threshold can be determined based on actual needs and are not limited here. Real-time monitoring can be performed using multiple sensors to detect smoke concentration, temperature, and infrared radiation intensity. If, during the monitoring process, any indicator (smoke concentration, temperature, or infrared radiation intensity) exceeds the preset threshold, it indicates that the battery may be overheating or experiencing other dangerous reactions, and the target battery is immediately determined to be on fire. If none of the three indicators exceeds the preset threshold, it indicates that the target battery is not abnormal, and the target battery is determined to be not on fire. This judgment process is based on the principle of correlation between environmental changes detected by different sensors and the physical phenomenon of battery fire, thereby providing timely and accurate judgment basis for battery safety management.

[0067] Furthermore, in one embodiment, before the step of controlling the target vehicle to travel from the destination position to another position based on the target initial kinetic energy, the method further includes:

[0068] Determining a target remaining mileage range corresponding to the target initial kinetic energy based on a preset mapping relationship between the initial kinetic energy range and the remaining mileage range;

[0069] For each target position within the target remaining mileage range, determining a target remaining mileage based on a target initial kinetic energy and a road surface friction coefficient and a slope corresponding to the target position;

[0070] The target position corresponding to the maximum value of all target remaining distances is used as the other position.

[0071] Exemplarily, in an embodiment of the present application, the mapping relationship between the preset initial kinetic energy range and the remaining mileage range can be obtained through experimental calibration, which is not limited here; after calculating the target initial kinetic energy corresponding to the target vehicle, the initial kinetic energy range where the target initial kinetic energy is located can be found in combination with the mapping relationship, and then the remaining mileage range corresponding to the initial kinetic energy range where the target initial kinetic energy is located can be used as the target remaining mileage range; multiple target positions are obtained from the target remaining mileage range, and for each target position within the target remaining mileage range, the target initial kinetic energy and the road friction coefficient and slope of the target position are combined to calculate, so as to determine the target remaining mileage of the target position; the target position corresponding to the maximum value among all the calculated target remaining mileages is selected as the other position.

[0072] Specifically, assuming that the target initial kinetic energy corresponding to the target vehicle is 30 kWh, according to the mapping relationship between the preset initial kinetic energy range and the remaining mileage range, the target initial kinetic energy of 30 kWh corresponds to a target remaining mileage range of 15 to 30 kilometers; several target locations are selected within this target remaining mileage range, such as location A (10 kilometers from the destination location, a road friction coefficient of 0.6, and a slope of 2%), location B (15 kilometers from the destination location, a road friction coefficient of 0.5, and a slope of 0.5%), and location C (20 kilometers from the destination location, a road friction coefficient of 0.7, and a slope of 3%); based on the target initial kinetic energy of 30 kWh and the road friction coefficient and slope of each target location, the target remaining mileage for the target vehicle to reach each target location is calculated, wherein the target initial kinetic energy, road friction coefficient, and slope can be substituted into the following calculation formula to obtain the target remaining mileage, which is as follows:

[0073] d=f(E,μ,θ)

[0074] Where E is the initial kinetic energy of the target; μ is the slope; θ is the road friction coefficient; and d is the remaining mileage of the target.

[0075] It should be noted that the target remaining mileage can also be calculated through experimental calibration. For example, through experiments, when the target initial kinetic energy is a1, the road friction coefficient is b1, and the slope is c1, the corresponding target remaining mileage is d1; when the target initial kinetic energy is a2, the road friction coefficient is b2, and the slope is c2, the corresponding target remaining mileage is d2; when the target initial kinetic energy is a3, the road friction coefficient is b3, and the slope is c3, the corresponding target remaining mileage is d3; assuming that the target initial kinetic energy corresponding to the target vehicle is a2, the road friction coefficient of the current road is b2, and the slope of the current road is c2, then the corresponding target remaining mileage can be determined as d2 based on the above mapping relationship.

[0076] It is understandable that, assuming the following results are obtained through calculation: the target remaining mileage to reach position A is 12 kilometers, the target remaining mileage to reach position B is 16 kilometers, and the target remaining mileage to reach position C is only 15 kilometers; by comparing all the calculated target remaining mileages, it is found that the target remaining mileage corresponding to position B is the largest (16 kilometers), so position B can be used as the other positions, that is, the farthest distance point that the target vehicle can reach under the target initial kinetic energy conditions.

[0077] Furthermore, in one embodiment, after the step of controlling the door to unlock, the method further includes:

[0078] The safety belt is controlled to be released and at least one of the reclining angle, front and rear position or height of the seat is adjusted to help the target person evacuate.

[0079] For example, in an embodiment of the present application, in an emergency, to facilitate the smooth evacuation of a target individual, the seatbelt must first be released. After the release of the seatbelt, at least one of the seat's tilt angle, fore-aft position, or height can be adjusted to optimize the target individual's evacuation path and maneuverability. Real-time monitoring and rapid response ensure that, after the seatbelt is released, the seat is quickly adjusted to the most optimal position for evacuation, thereby providing the target individual with the most efficient and safe evacuation conditions possible.

[0080] Furthermore, in one embodiment, adjusting at least one of the tilt angle, fore-aft position, or height of the seat includes:

[0081] Control the seat's tilt angle to tilt forward to reduce the time the target person is restrained in the seat;

[0082] Or adjust the front and rear position of the seat according to the target person's sitting posture to provide the target person with escape space;

[0083] Alternatively, the seat may be controlled to reach a target height based on the height of the target person to increase the target person's freedom of movement.

[0084] Exemplarily, in the embodiment of the present application, the target height can be set according to the specific height of different target objects, which is not limited here; the comfort and freedom of movement of the target person can be improved by adjusting at least one parameter of the seat's tilt angle, fore-and-aft position or height. Specifically, the seat's tilt angle can be controlled to tilt it forward, thereby reducing the time the target person is restrained in the seat, reducing discomfort, and enhancing their mobility; or the fore-and-aft position of the seat can be adjusted according to the target person's sitting posture to provide them with more escape space, thereby improving their ability to respond in emergency situations. For example, if the target person sits upright with his back close to the seat back, it indicates that he is ready to quickly In order to increase the leg room for quick reaction, the seat can be adjusted back a certain distance based on the target person's height to achieve a suitable escape posture, thereby improving the target person's physical comfort and maximizing their freedom of movement. It should be noted that the key to adjusting the seat height according to height is to ensure that the target person's feet can touch the ground smoothly, the knees form a comfortable angle, and they can stand up and escape quickly in an emergency. For shorter target persons, the seat can be lowered appropriately to ensure flexible movement when standing; for taller target persons, the seat can be raised appropriately to ensure the knee angle is appropriate, thereby facilitating quick reaction and escape. The above adjustment plan aims to help target persons maintain high mobility and freedom of movement in specific environments by optimizing various parameters of the seat.

[0085] In a second aspect, an embodiment of the present application also provides a vehicle safety control system.

[0094] If the smoke concentration is greater than the preset concentration threshold, the temperature is greater than the preset temperature threshold, and the infrared radiation intensity is greater than the preset intensity threshold, it is determined that the target battery is not on fire.

[0098] The target position corresponding to the maximum value of all target remaining distances is used as the other position.
