Description

Technical Field

[0001] This invention relates to the field of flying car technology, and in particular to a multimodal energy recovery method, apparatus, equipment and program product for flying cars. Background Technology

[0002] As a new type of transportation that combines ground driving and low-altitude flight, the energy consumption of flying cars is one of the core bottlenecks restricting their industrialization. Unlike traditional cars, which only need to cope with ground resistance, flying cars must overcome multiple loads such as gravity and air resistance during takeoff, hovering, flight, and landing, resulting in a much higher energy consumption rate than traditional vehicles. At the same time, the braking energy during ground driving, the gravitational potential energy during deceleration and landing, and the wind energy generated by interaction with the air during flight are not effectively recovered and utilized, leading to low energy efficiency and limited driving range.

[0003] In existing technologies, energy recovery solutions are mostly designed for a single driving state. For example, braking energy recovery technology for ground vehicles is only applicable to rolling wheel scenarios and cannot be adapted to flight. Some drone energy recovery solutions only focus on kinetic energy recovery during propeller deceleration, ignoring energy losses in multiple scenarios such as ground driving and landing impact. This "single-scenario adaptation" recovery mode cannot meet the energy recovery needs of flying cars operating in multiple modes from "ground to air," resulting in problems such as incomplete coverage of recovery scenarios, low energy recovery efficiency, and poor system compatibility.

[0004] The above problems urgently need to be addressed. Summary of the Invention

[0005] The purpose of this invention is to at least partially solve one of the technical problems existing in the prior art.

[0006] Therefore, one objective of this invention is to provide a multimodal energy recovery method for flying cars. This method can achieve efficient recovery and utilization of various types of energy, such as kinetic energy, potential energy, and wind energy, in multiple scenarios including ground driving, air flight, take-off and landing of flying cars, thereby improving the energy utilization rate of flying cars and extending their driving range.

[0007] Another objective of this invention is to provide a multimodal energy recovery device for flying cars.

According to the target energy recovery mode, the corresponding energy recovery actuator is controlled to perform energy recovery conversion, and the converted electrical energy is stored in the energy storage system.

[0009] Furthermore, in one embodiment of the present invention, the dynamic parameters include speed, altitude, vertical acceleration, propeller speed, and brake pedal travel. The step of identifying the current operating state of the target flying car based on the dynamic parameters specifically includes: When the propeller rotation speed is 0 and the speed is greater than 0, the current operating state is determined to be ground driving state; When the propeller speed is greater than or equal to a preset first threshold and the vertical acceleration is greater than 0, the current operating state is determined to be the takeoff state; When the propeller speed is greater than or equal to a preset second threshold, the altitude fluctuation is less than or equal to a preset third threshold, and the speed is greater than or equal to a preset fourth threshold, the current operating state is determined to be an aerial cruise state. When the speed continues to decrease and the propeller speed is less than a preset fifth threshold, the current operating state is determined to be an in-flight deceleration state.

When the current operating state is in-flight deceleration state, the flight deceleration recovery mode is determined to be the target energy recovery mode; When the current operating state is the landing state, the landing potential energy recovery mode is determined to be the target energy recovery mode.

[0011] Furthermore, in one embodiment of the present invention, when in ground braking recovery mode, the corresponding braking power generation is determined according to the braking intensity, and the braking power generation is used to drive the brake motor to reverse and generate electricity through the wheels of the target flying car, thereby converting the kinetic energy of ground travel into electrical energy.

[0012] Furthermore, in one embodiment of the present invention, when in wind-assisted recovery mode, the pitch angle and direction of the propeller of the flight propulsion system are adjusted according to the wind direction collected by the wind speed sensor, so that the propeller is in the windward state, thereby using wind energy to drive the propeller to rotate and drive the motor to generate electricity.

[0013] Furthermore, in one embodiment of the present invention, when in flight deceleration and recovery mode, the propeller of the flight propulsion system is controlled to reduce its rotation speed, the propeller drive motor is switched to generator mode, and the drag coefficient of the propeller drive motor is adjusted according to the deceleration requirements, thereby using the inertia of the target flying car to drive the propeller to rotate and generate electricity, converting the kinetic energy of flight into electrical energy.

[0014] Furthermore, in one embodiment of the present invention, when in the landing potential energy recovery mode, the real-time potential energy change rate is determined according to the altitude change, and the power generation speed of the propeller drive motor is adjusted according to the real-time potential energy change rate, thereby converting the gravitational potential energy of the target flying car into electrical energy.

[0018] On the other hand, embodiments of the present invention also provide a computer program product, including a computer program that, when executed by a processor, implements the above-described multimodal energy recovery method for flying cars.

[0027] Reference Figure 1 This invention provides a multimodal energy recovery method for flying cars, specifically including the following steps: S101. Obtain the dynamic parameters and environmental parameters of the target flying car; S102. Identify the current operating status of the target flying car based on the dynamic parameters, and obtain several corresponding target energy recovery modes based on the current operating status and environmental parameters. S103. Control the corresponding energy recovery actuator to perform energy recovery conversion according to the target energy recovery mode, and store the converted electrical energy into an energy storage system.

[0028] Specifically, the flying car in this embodiment of the invention includes a ground driving system, a flight propulsion system, an energy storage system, and an energy recovery control unit. The multimodal energy recovery method includes the following steps: 1. Operational Status Identification: The energy recovery control unit collects the flying car's speed, acceleration, altitude, attitude angle, power system operating mode, and environmental parameters in real time through onboard sensors to identify the current operational status; the operational status includes ground driving status, takeoff status, air cruise status, air deceleration status, and landing status.

[0029] 2. Energy recovery mode matching: Based on the identified operating status, the corresponding energy recovery mode is matched. The energy recovery modes include ground braking recovery mode, flight deceleration recovery mode, landing potential energy recovery mode, and wind energy-assisted recovery mode. Different operating statuses can trigger the operation of a single or multiple recovery modes in combination.

[0030] 3. Energy recovery execution: Energy is converted into electrical energy and stored in the energy storage system through the actuator corresponding to the recovery mode; 4. Dynamic adjustment and feedback: Real-time monitoring of the SOC status of the energy storage system and the working parameters of the recovery mechanism, dynamically adjusting the energy distribution ratio of each recovery mode to avoid overload or energy waste.

[0031] The embodiments of the present invention can achieve efficient recovery and utilization of various types of energy, such as kinetic energy, potential energy, and wind energy, in multiple scenarios such as ground driving, air flight, take-off and landing of flying cars, thereby improving the energy utilization rate of flying cars and extending their driving range.

[0032] As a further optional implementation, the dynamic parameters include speed, altitude, vertical acceleration, propeller speed, and brake pedal travel. The current operating state of the target flying car is identified based on these dynamic parameters, specifically including: S201. When the propeller speed is 0 and the speed is greater than 0, the current operating state is determined to be ground driving state. S202. When the propeller speed is greater than or equal to the preset first threshold and the vertical acceleration is greater than 0, the current operating state is determined to be the takeoff state. S203. When the propeller speed is greater than or equal to the preset second threshold, the altitude fluctuation is less than or equal to the preset third threshold, and the speed is greater than or equal to the preset fourth threshold, the current operating state is determined to be the aerial cruise state. S204. When the speed continues to decrease and the propeller speed is less than the preset fifth threshold, the current operating state is determined to be an in-flight deceleration state. S205. When the vertical acceleration is less than 0 and the speed is less than the preset sixth threshold, the current running state is determined to be the landing state.

[0033] Specifically, the vehicle-mounted sensors include speed sensors, acceleration sensors, altitude sensors, gyroscopes, powertrain status sensors, and wind speed sensors; environmental parameters include wind speed and wind direction.

[0034] Specifically, the energy recovery control unit uses speed sensors, acceleration sensors, GPS altitude sensors, three-axis gyroscopes, power system status sensors, and ultrasonic wind speed sensors to collect real-time data on the flying car's speed v and vertical acceleration. Altitude h, attitude angle θ (pitch angle), propeller speed n, brake pedal travel s, and ambient wind speed α is the wind direction, and the operating status is identified according to the following rules: 1) When the propeller speed n=0 and the travel speed v>0, it is determined to be in ground travel state; 2) When the propeller speed n ≥ 1500 r / min and the height h continues to increase, the vertical acceleration... When the value is greater than 0, it is determined to be in takeoff condition; 3) When the propeller speed n≥1200r / min, the altitude h fluctuation≤5m and the travel speed v>50km / h, it is determined to be in the air cruise state; 4) When the travel speed v continues to decrease and the propeller speed n < 1000 r / min, it is determined to be in mid-air deceleration state; 5) When the height h continues to decrease and the vertical acceleration When the speed v is less than 0 and the driving speed v is less than 30 km / h, it is determined to be a landing state.

[0035] As an optional implementation, environmental parameters include wind speed. Based on the current operating status and environmental parameters, several target energy recovery modes are obtained, specifically including: S301. When the current operating state is ground driving state and the brake pedal travel is greater than or equal to the preset seventh threshold, the ground braking recovery mode is determined to be the target energy recovery mode. S302. When the current operating state is takeoff state and the vertical acceleration is less than or equal to the preset eighth threshold, the wind energy assisted recovery mode is determined as the target energy recovery mode. S303. When the current operating state is space cruise state or air deceleration state, and the wind speed is greater than or equal to the preset ninth threshold, the wind energy assisted recovery mode is determined as the target energy recovery mode. S304. When the current operating state is in-flight deceleration state, determine the flight deceleration recovery mode as the target energy recovery mode; S305. When the current operating state is landing, determine the landing potential energy recovery mode as the target energy recovery mode.

[0036] Specifically, based on the above state identification results, the recycling mode is matched according to the following rules: 1) When the operating state is ground driving state and a braking signal is detected, the ground braking recovery mode is triggered; 2) When the operating state is in the air deceleration state, the flight deceleration recovery mode is triggered; 3) When the running status is in the landing state and the altitude continues to decrease, the landing potential energy recovery mode is triggered; 4) When the operating status is aerial cruise and the ambient wind speed is... When the wind speed is ≥3m / s, the wind energy-assisted recovery mode is triggered; 5) When the operating state is takeoff and the vertical acceleration is... When the amount is ≤0.5g, the wind energy recovery mode can be triggered.

[0037] The ground braking recovery unit of this invention includes a braking motor, a braking intensity sensor, and a power adjustment module; the flight deceleration recovery unit and the landing potential energy recovery unit share a propeller drive motor, and the driving and power generation modes are switched through a motor mode switching switch; the wind energy assisted recovery unit includes a pitch adjustment mechanism, a wind direction tracking sensor, and a speed control module.

[0038] As a further optional implementation, when in ground braking recovery mode, the corresponding braking power generation is determined according to the braking intensity, and the braking power generation is used to drive the brake motor to reverse and generate electricity through the wheels of the target flying car, thereby converting the kinetic energy of ground travel into electrical energy.

[0039] Specifically, the execution process of the ground braking regeneration mode is as follows: The energy recovery control unit controls the wheel braking mechanism of the ground driving system to switch to power generation mode. The wheels drive the brake motors in reverse to generate electricity, converting the kinetic energy of ground travel into electrical energy. Simultaneously, the power generation is adjusted according to the braking intensity signal; the greater the braking intensity, the higher the proportion of power generation, ensuring braking safety. Controlling the wheel brake motors to switch to power generation mode causes the wheels to drive the motors in reverse to generate electricity. The power generation P1 is proportional to the brake pedal travel s; for example, when s=5mm, P1=5kW, and when s=20mm, P1=20kW, ensuring the braking distance meets safety standards.

[0040] As a further optional implementation, when in wind-assisted recovery mode, the pitch angle and direction of the propeller of the flight propulsion system are adjusted according to the wind direction collected by the wind speed sensor, so that the propeller is in the windward state, thereby using wind energy to drive the propeller to rotate and drive the motor to generate electricity.

[0041] Specifically, the wind-assisted energy recovery mode operates as follows: based on wind speed and direction data collected by a wind speed sensor, the propeller pitch angle and direction are adjusted to position the propeller facing the wind, utilizing wind energy to drive the propeller's rotation and power the generator. When the flight direction is opposite to the wind direction, the pitch angle is increased to improve wind energy capture efficiency. For example, by adjusting the propeller pitch angle to 30° using a wind direction tracking sensor, the propeller rotates facing the wind, generating power P2 and... Proportional When the speed is 5m / s, P2 = 8kW. When the speed is 10 m / s, P2 = 64 kW.

[0042] As a further optional implementation, when in flight deceleration and recovery mode, the propeller of the flight propulsion system is controlled to reduce its rotation speed, the propeller drive motor is switched to generator mode, and the drag coefficient of the propeller drive motor is adjusted according to the deceleration requirements, thereby using the inertia of the target flying car to drive the propeller to rotate and generate electricity, converting the kinetic energy of flight into electrical energy.

[0043] Specifically, the execution process of the flight deceleration and recovery mode is as follows: The propeller of the flight propulsion system is controlled to reduce its rotational speed, while the propeller drive motor is switched to generator mode. The inertia of the flying car drives the propeller to rotate and generate electricity, converting the kinetic energy of flight into electrical energy. The drag coefficient of the propeller is adjusted according to the deceleration requirements to achieve a balance between deceleration effect and recovery efficiency. When the propeller drive motor is switched to generator mode, the propeller continues to rotate under inertia. The power generation P3 is adjusted according to the deceleration requirements. When rapid deceleration is required, the propeller drag coefficient is increased, and P3 can reach 30kW.

[0044] As a further optional implementation, when in the landing potential energy recovery mode, the real-time potential energy change rate is determined according to the altitude change, and the power generation speed of the propeller drive motor is adjusted according to the real-time potential energy change rate, thereby converting the gravitational potential energy of the target flying car into electrical energy.

[0045] Specifically, the execution process of the landing potential energy recovery mode is as follows: combining data from the altitude sensor and the speed sensor, the real-time potential energy change rate is calculated, and the propeller drive motor is controlled to generate electricity at a preset speed, converting gravitational potential energy into electrical energy; at the same time, the attitude angle is monitored by the gyroscope, and when the attitude angle deviation exceeds ±5°, the recovery power is reduced to prioritize ensuring landing stability.

[0046] Calculate the potential energy power based on the rate of change of height h, and control the propeller drive motor to generate electricity at the corresponding speed. The generated power is... (m is the mass of the flying car, g is the acceleration due to gravity). When the attitude angle θ exceeds ±5°, P4 decreases to 50%.

[0047] In some optional embodiments, the specific method of dynamic adjustment is as follows: when the SOC of the energy storage system is ≥90%, the power generation of each recovery mode is reduced to less than 30% of the rated power; when the SOC is ≤30%, priority is given to ensuring the energy distribution of the flight deceleration recovery mode and the landing potential energy recovery mode, and their energy proportion is not less than 60% of the total recovered energy; 16. when the temperature of any recovery unit exceeds 85°C, the cooling fan is triggered, and the power generation of the corresponding unit is reduced to 50% until the temperature drops below 60°C.

[0048] The method steps of the embodiments of the present invention have been described above. It can be understood that the embodiments of the present invention can achieve efficient recovery and utilization of various types of energy, such as kinetic energy, potential energy, and wind energy, in multiple scenarios such as ground driving, air flight, take-off and landing of flying cars, thereby improving the energy utilization rate of flying cars and extending their driving range.

[0049] Compared with the prior art, the embodiments of the present invention have the following advantages: 1. Multi-scenario full coverage: By identifying the full operating cycle status of the flying car and matching the corresponding energy recovery mode, this invention realizes energy recovery in multiple scenarios such as ground braking, in-flight deceleration, landing potential energy and wind energy assistance, solving the problem of single recovery scenario in traditional solutions and significantly improving the coverage of energy recovery.

[0050] 2. High-efficiency energy utilization: Through the coordinated operation of multiple recovery modes and dynamic energy distribution, the flying car can convert various forms of energy, such as kinetic energy, potential energy, and wind energy, into electrical energy storage in different scenarios, which can improve the overall energy utilization rate of the flying car and extend its driving range.

[0051] 3. Safety and efficiency balance: During the energy recovery process, parameters such as braking intensity, attitude angle, and energy storage status are monitored in real time to dynamically adjust the recovery power and mode priority, ensuring that the driving stability, braking safety, and take-off and landing reliability of the flying car are not affected while recovering energy.

[0052] 4. Strong system compatibility: The recovery system of this invention can be seamlessly integrated with the ground driving system and flight propulsion system of existing flying cars. Functional expansion can be achieved through motor mode switching and control logic optimization, without the need for large-scale modification of the original power system, thus reducing the cost of industrial application.
