[0047] The following will describe the embodiments of the present application with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand the 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 embodiments, 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 the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

[0048] The first embodiment of the present application provides a flying car parachute system, such as Figure 1 The flying car parachute system includes: a vehicle body 100, a propeller 101, a parachute 102, an air suspension unit 103 and a control unit 104.

[0049] The propeller 101 is arranged on the top of the vehicle body 100. The propeller 101 includes a receiving cavity, and the deceleration parachute 102 is arranged in the receiving cavity. The air suspension unit 103 is used to drive the deceleration parachute 102 to pop out of the receiving cavity through compressed air under the control signal of the control unit 104.

[0050] The vehicle body 100 refers to the main body of the flying car. The number of propellers 101 is not limited and can be one or more. For example, the number can be determined based on the propeller power and the vehicle weight. It should be understood that each propeller 101 corresponds to a parachute 102. When there are multiple propellers 101, each propeller 101 includes a cavity for accommodating the parachute 102. The air suspension unit 103 can be the flying car's own air suspension system, thereby fully utilizing existing vehicle components and reducing costs. The parachute is powered by compressed air, eliminating concerns about fuel moisture or damage to the parachute due to fuel combustion. Because the flying car parachute system uses compressed air from the flying car's own air suspension unit to power the parachute, it greatly improves the reliability of the parachute and the safety of the flying car.

[0051] In a specific embodiment, the structural diagram of the flying car parachute system is as follows: Figure 2 , wherein the propeller 101 includes blades 203 and a rotating center portion 202. The bottom of the rotating center portion 202 is fixed to the top of the vehicle body 100, the blades 203 are fixed to the side of the rotating center portion 202, and the accommodating cavity 201 is arranged at the top of the rotating center portion 202. The rotating center portion 202 can be a cylindrical structure, and the accommodating cavity 201 is a concave structure at the top center of the rotating center portion 202, or the accommodating cavity 201 can also be a cylindrical structure arranged at the concave structure at the top of the rotating center portion 202, without limitation. The number of blades 203 can be set as needed, and the embodiment of the present application does not limit the number of blades 203.

[0052] In one embodiment, the accommodating chamber 201 further includes a cover plate, which is disposed at the opening of the accommodating chamber 201. The cover plate may be a flip-top structure, and the connection between the cover plate and the accommodating chamber opening may be a rotatable connection. For example, when the control unit 104 outputs a control signal, the cover plate is first controlled to open, and then the parachute is driven by compressed air to eject from the accommodating chamber.

[0053] In one embodiment, the air suspension unit 103 includes an air compressor 204 , an air tank 205 , and an air distribution valve 206 .

[0054] The air path distribution valve 206 is connected to the air compressor 204, the air tank 205 and the accommodating chamber 201 through air paths respectively. The air compressor 204 is used to generate compressed air and store the compressed air in the air tank 205. The air path distribution valve 206 is used to transmit the compressed air in the air tank 205 to the accommodating chamber 201 through the air path under the control signal of the control unit, so as to eject the deceleration parachute 102 from the accommodating chamber 201.

[0055] In this embodiment, the air compressor 204, air tank 205, and air distribution valve 206 can be components of the flying car's built-in air suspension system, thereby fully utilizing existing vehicle components and significantly reducing costs. The air compressor 204, air tank 205, and accommodating chamber 201 are each connected to the air distribution valve 206 via air circuits. The flow of compressed air is controlled by opening and closing various valves in the air distribution valve 206.

[0056] In one embodiment, the air suspension unit 103 further includes a pressure sensor for detecting the tank pressure of the compressed air in the air tank 205 .

[0057] The control unit 104 is also used to control the air compressor 204 to start working when the air tank pressure is less than a first pressure threshold, and to control the air compressor 204 to stop working when the air tank pressure is greater than or equal to a second pressure threshold; the second pressure threshold is greater than the first pressure threshold.

[0058] In this embodiment, in order to ensure that the pressure of the compressed air in the air tank is sufficient to support the normal function of the air suspension unit and the pressure requirement when the parachute needs to be deployed, the air tank pressure of the compressed air in the air tank can be detected in real time by a pressure sensor. When the air tank pressure is less than a first pressure threshold, the air compressor 204 is controlled to start working, and when the air tank pressure is greater than or equal to a second pressure threshold, the air compressor 204 is controlled to stop working. Since the second pressure threshold is greater than the first pressure threshold, frequent starting of the air compressor is avoided, thereby improving the life of the air compressor.

[0059] In one embodiment, the deceleration parachute 102 includes a parachute body and a towing rope, wherein the towing rope is connected to the parachute body and the receiving cavity respectively.

[0060] In this embodiment, the deceleration parachute is fixed to the accommodating cavity by a traction rope. The number of traction ropes is not limited, for example, there can be 4, 6, 8 or more traction ropes. One end of the traction rope is connected to the parachute body, and the other end is connected to the accommodating cavity.

[0061] In one embodiment, the accommodating cavity is detachably connected to the rotation center portion.

[0062] After the parachute is deployed in an emergency, restoring the parachute is time-consuming and requires specialized skills. Therefore, a removable connection between the housing chamber and the rotating center can be provided. For example, the connection can be rotationally connected via a threaded structure, with a male threaded head provided at the outer bottom of the housing chamber and a matching female threaded head provided at the rotating center, allowing the housing chamber and the rotating center to be connected and removable via the threaded structure. Alternatively, a female threaded head can be provided at the outer bottom of the housing chamber and a matching male threaded head can be provided at the rotating center, without limitation. Alternatively, the housing chamber and the rotating center can be provided with other removable connections, such as a snap-on connection, without limitation. After the parachute is used once, the driver can remove the used housing chamber and replace it with a spare one, ensuring the vehicle's stability and safety. Since the parachute is located within the housing chamber, only the compressed air path connecting the housing chamber to the compressed air path needs to be replaced. The air path can be integrated into the removable connection structure, and the air path is connected after the housing chamber is replaced and secured, thereby improving the recovery speed of the parachute after use.

[0063] In one embodiment, the flying car parachute system further includes: a brake controller, an inertial measurement unit, a vehicle controller, and an intelligent driving controller.

[0064] The brake controller is used to measure the flying car's speed; the inertial measurement unit is used to collect the flying car's vertical and longitudinal accelerations; the vehicle controller is used to obtain the flying car's driving mode and active parachute deployment signals (driving modes include flight mode and land mode); and the intelligent driving controller is used to collect obstacle information. Vertical acceleration refers to the flying car's acceleration perpendicular to the ground, and longitudinal acceleration refers to the flying car's acceleration in the horizontal forward direction.

[0065] The control unit is used to output a control signal when the parachute opening conditions are met, so as to drive the deceleration parachute to pop out of the accommodation chamber and open through compressed air.

[0066] Among them, the parachute opening conditions include at least one of the following conditions:

[0067] Obtain active parachute opening signal;

[0068] In flight mode, the vertical acceleration exceeds the preset acceleration threshold and the flight system fails;

[0069] In land mode, the risk of collision is determined based on vehicle speed, longitudinal acceleration and obstacle information.

[0070] In this embodiment, the control unit interacts with the brake controller, inertial measurement unit, vehicle controller, and intelligent driving controller via an onboard bus. The brake controller can detect the current speed of the flying car, the inertial measurement unit (IMU) can detect the vertical and longitudinal accelerations of the flying car, the vehicle controller can obtain the flying car's driving mode and the driver's input for active parachute deployment, and the intelligent driving controller can collect information about obstacles ahead, such as obstacle size, type, and distance. The type of onboard bus is not limited and can be, for example, a CAN bus, Ethernet, or other bus. When an active parachute deployment signal is received, indicating that the driver wishes to deploy the parachute, the control unit directly outputs a control signal to eject the parachute from the containment chamber using compressed air. In flight mode, if the vertical acceleration exceeds a preset acceleration threshold and the flight system malfunctions, indicating that the flying car is in a critical state, the control unit outputs a control signal to eject the parachute from the containment chamber using compressed air to ensure a smooth landing of the flying car. In land mode, if it is determined based on vehicle speed, longitudinal acceleration, and obstacle information that the current braking system cannot avoid the risk of collision even at full power, the braking performance needs to be further improved. At this time, the parachute can be deployed to stop the flying car as quickly as possible to avoid a collision.

[0071] Figure 3 A schematic diagram of a flying car parachute control method provided in one embodiment of the present application includes:

[0072] Step S101, parachute opening intention judgment: The control unit receives the driver's parachute opening intention judgment signal sent by the vehicle controller. If the driver has the intention, the process jumps to step S105, otherwise it goes to step S102.

[0073] Step S102: Driving mode determination. The control unit receives the driving mode signal sent by the vehicle controller and determines the type of driving mode. If it is flight mode, the process proceeds to step S103; if it is land mode, the process proceeds to step S104.

[0074] In step S103, the longitudinal acceleration is greater than the threshold and the flight system is faulty. The control unit continuously detects and determines the longitudinal acceleration provided by the inertial measurement unit (IMU) and the flight system fault. If the longitudinal acceleration is greater than the threshold and the flight system is faulty, the control unit proceeds to step S105. Otherwise, the control unit remains in step S103 and repeats the determination.

[0075] Step S104: Collision risk assessment. The control unit performs a real-time, cyclic assessment of the longitudinal acceleration provided by the IMU, the obstacle distance provided by the intelligent driving controller, and the vehicle speed provided by the brake controller. If a collision risk exists, the process proceeds to step S105; otherwise, the process remains at step S104. The specific method for risk assessment is as follows:

[0076] ① Call the Autonomous Emergency Braking (AEB) control algorithm to confirm whether the vehicle has a potential collision risk based on the vehicle's speed, acceleration, and distance to the vehicle in front in real time.

[0077] ② In the event of a potential collision risk, AEB determines whether the collision can be avoided based on the maximum braking capacity of the hydraulic brake.

[0078] ③ If it cannot be avoided, it is considered that there is a collision risk; otherwise, there is no collision risk.

[0079] Step S105, system operation, mainly refers to the control unit opening the air distribution valve connecting the air compressor, the air tank and the parachute, and driving the air compressor to work.

[0080] Step S106: Open the parachute. After the system starts working, high-pressure gas immediately enters the parachute installation area, and the parachute is compressed by the high-pressure gas and opens quickly. Figure 4 , is a schematic diagram of parachute opening in flight mode, such as Figure 5 , which is a schematic diagram of parachute opening in land mode.

[0081] In this embodiment, the flying car parachute system utilizes the vehicle's existing air suspension unit components, such as an air tank, an air compressor, and a distribution valve, which can reduce costs. The parachute is deployed using high-pressure compressed air, which is more reliable than existing technologies. For example, there is no need to worry about the fuel getting wet or damaging the parachute when the fuel burns. Furthermore, it can provide both protection during flight and deceleration on land, and can actively deploy the parachute according to the pilot's wishes. Compared with existing technologies, it has a wider range of applications. Furthermore, the control logic used in the parachute deployment process is rigorous, which can avoid false triggering and improve reliability.

[0083] The control unit outputs a control signal when the parachute opening conditions are met;

[0084] Under the action of the control signal, the air suspension unit drives the deceleration parachute to pop out from the accommodation cavity through compressed air.

[0085] In this method, since the flying car deceleration parachute system drives the deceleration parachute through the compressed air of the air suspension unit of the flying car itself, the reliability of the deceleration parachute and the safety of the flying car can be greatly improved.
