Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically to an emergency propulsion device for a vehicle, a method for using the emergency propulsion device, and a corresponding vehicle. Background Technology

[0002] With the rapid popularization of automobiles and the booming development of the ride-hailing industry, it has become increasingly common for drivers to spend long periods of time inside their vehicles. For ride-hailing and private car drivers, most of their time is spent waiting for orders or driving, leaving them with little time or opportunity for physical exercise to maintain their health. For ordinary users, there is also a lack of effective exercise facilities inside the vehicle during long periods of waiting or charging at charging stations. Currently, with limited interior space and the absence of any exercise equipment, drivers have virtually no opportunity for effective physical exercise while driving.

[0003] On the other hand, cars, especially electric vehicles, often face the risk of running out of power or experiencing powertrain failures that render them unable to continue driving. Drivers often face difficulties when, for example, an electric vehicle's high-voltage battery runs out of power and there are no available charging facilities nearby, or when a powertrain failure causes the vehicle to break down. Especially when the driver is alone, pushing the vehicle to the nearest safe location, charging station, or repair shop is extremely difficult. Even if the destination is only tens or even a few meters away, the driver may not be able to move the heavy vehicle there alone.

[0004] Therefore, there is still a real need for improvement in providing fitness functions inside vehicles and in addressing emergency mobility in the event of vehicle power failure. Summary of the Invention

[0029] The invention will now be described in more detail with reference to the accompanying drawings, which will provide a better understanding of its principles, features, and advantages.

Detailed Implementation

[0030] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the scope of protection of the present invention. Various embodiments may share the same view or multiple views for description, but not all features appearing in the same view should be interpreted as features that must be present in an embodiment.

[0031] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] Figure 1 A schematic interior side view of the arrangement of an emergency propulsion device 1000 in a vehicle 2000 according to an embodiment of the present invention is shown.

[0033] like Figure 1 As illustrated, vehicle 2000 can be any type of vehicle and includes the emergency propulsion device 1000, which will be described in detail below. The emergency propulsion device 1000 is integrally installed inside vehicle 2000. The emergency propulsion device 1000 works in conjunction with other systems of vehicle 2000 (such as braking system, steering system, etc.), without affecting the original functions and performance of vehicle 2000 during normal driving, providing in-vehicle movement and emergency propulsion functions only when needed.

[0034] The emergency propulsion device 1000 comprises three main functional components: a rowing machine 2100, an energy storage device 2200, and an emergency power transmission system 2300. The rowing machine 2100 is installed within the vehicle 2000 and configured to allow the user to perform rowing exercises inside the vehicle. The energy storage device 2200 is connected to the rowing machine 2100 and configured to convert the mechanical energy generated by the rowing motion into elastic potential energy for storage. The emergency power transmission system 2300 is located between the energy storage device 2200 and the wheels 2001 of the vehicle 2000 and is configured to release the elastic potential energy stored in the energy storage device 2200 and transfer it to the wheels 2001 to drive the vehicle 2000 when the vehicle 2000's power system fails or is depleted. These three main functional components of the emergency propulsion device 1000 work together to meet the driver's exercise needs inside the vehicle and provide emergency propulsion power in emergency situations.

[0035] like Figure 1 As schematically shown, the rowing machine device 2100 includes a driver's seat platform 2110, a sliding rail 2120, a rail locking device 2130, a rowing machine handle 2140, and a pull rope 2150. The driver's seat platform 2110 serves as the support platform for the driver's seat 2002 of the vehicle 2000 and is slidably mounted on the sliding rail 2120. The sliding rail 2120 is located on the vehicle floor of the vehicle 2000 and extends along the longitudinal direction (i.e., the front-to-back direction) of the vehicle 2000, providing motion guidance for the driver's seat platform 2110 to slide forward and backward. The rail locking device 2130 is configured to selectively lock or unlock the position of the driver's seat platform 2110 on the sliding rail 2120. Under normal driving conditions, the rail locking device 2130 is locked, and the driver's seat platform 2110 is fixed in the appropriate driving position on the sliding rail 2120, preventing forward and backward sliding and thus ensuring driving safety. When a user needs to perform rowing exercises inside the vehicle, the user operates the slide rail locking device 2130 to unlock it, allowing the driver's seat platform 2110 to slide freely back and forth along the sliding rail 2120, thereby simulating the back-and-forth movement of the body during rowing. The slide rail locking device 2130 can employ a mechanical locking pin, a latching mechanism, or other suitable locking / unlocking mechanism to achieve the aforementioned selective locking or unlocking function.

[0036] like Figure 1 As further illustrated, the rowing machine handle 2140 is positioned below the steering column of the vehicle 2000. There is typically some open space below the steering column, allowing the rowing machine handle 2140 to be conveniently located, making it easily accessible and operable by the driver from the driver's seat. One end of the pull cord 2150 is connected to the rowing machine handle 2140, and the other end is drively connected to the input of the energy storage device 2200. Specifically, the pull cord 2150 extends from the rowing machine handle 2140 to the front engine compartment area or dashboard area of ​​the vehicle 2000, connecting to the ratchet mechanism 2210 in the energy storage device 2200. When the user pulls the rowing machine handle 2140, the pull cord 2150 transmits the user's pulling force to the ratchet mechanism 2210, causing the ratchet mechanism 2210 to rotate. The pull rope 2150 can be made of high-strength steel wire rope, braided rope or other materials with sufficient tensile strength and abrasion resistance.

[0037] The rowing machine device 2100 is used for rowing exercises as follows: The user sits on the driver's seat platform 2110, unlocks the slide rail locking device 2130, and holds the rowing machine handles 2140 with both hands, pulling them backward (towards the body). During the pulling process, the user's body slides backward along the sliding rail 2120 with the driver's seat platform 2110, while the user straightens their legs to exert force, simulating the leg pushing and rowing motions in rowing. After the user releases the rowing machine handles 2140, the user can return their body and driver's seat platform 2110 to the forward position along the sliding rail 2120 by bending their legs, ready for the next pull. Repeating this process allows for an effective full-body rowing exercise inside the vehicle.

[0038] In an optional embodiment, the rowing machine device 2100 further includes a multi-level resistance adjustment mechanism 2160. The multi-level resistance adjustment mechanism 2160 is configured to allow the user to select different resistance levels. The resistance in rowing can originate from the reaction force required to tighten the energy storage device 2200, i.e., the resistance the user needs to overcome when pulling the rope 2150, which is the tightening resistance of the spiral spring energy storage mechanism 2230 in the energy storage device 2200. The multi-level resistance adjustment mechanism 2160 achieves different resistance levels by changing the transmission ratio of the reduction gear mechanism 2220 in the energy storage device 2200. Specifically, when the transmission ratio is large, the spiral spring tightening angle corresponding to each pull of the rope 2150 is larger, and the resistance the user needs to overcome is correspondingly increased, suitable for users requiring higher exercise intensity; when the transmission ratio is small, the spiral spring tightening angle corresponding to each pull is smaller, and the resistance is correspondingly reduced, suitable for users requiring lower exercise intensity. The multi-level resistance adjustment mechanism 2160 can be set with multiple switchable levels, similar to the gear mechanism of a bicycle. Users can switch between different levels using adjustment knobs, levers, or other operating elements inside the vehicle to select a suitable resistance level for their exercise. The multi-level resistance adjustment mechanism 2160 allows the rowing machine device 2100 to meet the usage requirements of users with different fitness levels and different exercise needs, improving the applicability and user experience of the rowing machine device 2100.

[0039] Figure 2 A schematic structural diagram of an energy storage device 2200 and an emergency power transmission system 2300 according to an embodiment of the present invention is shown.

[0040] like Figure 2 As illustrated, the energy storage device 2200 comprises three main components: a ratchet spring mechanism 2210, a reduction gear mechanism 2220, and a spiral spring energy storage mechanism 2230. These three components are sequentially connected to form a complete energy conversion path from the user's pulling action to the storage of elastic potential energy.

[0041] The ratchet spring mechanism 2210 is connected to the rowing machine device 2100 and configured to convert the user's reciprocating pulling motion into unidirectional rotational motion. Specifically, the ratchet spring mechanism 2210 includes a ratchet and a cooperating pawl. When the user pulls the ratchet spring mechanism 2210 via the pull rope 2150, the ratchet rotates in a preset direction (e.g., clockwise); when the user releases the pull rope 2150, the pawl engages in the teeth of the ratchet, preventing the ratchet from rotating in the opposite direction, thus keeping the ratchet in its current rotational position without reversing. The ratchet spring mechanism 2210 is configured to rotate by a preset angle each time the user pulls. This preset angle depends on the number of teeth on the ratchet and the travel setting of the pull rope 2150; for example, each pull may cause the ratchet to rotate half a turn or a full turn. Through repeated pulling, the ratchet spring mechanism 2210 accumulates multiple rotations, gradually converting the user's reciprocating motion into a continuous unidirectional rotational output.

[0042] The ratchet spring mechanism 2210 also includes a ratchet lock-up release mechanism (not specifically shown). This mechanism is configured to selectively release the one-way lock of the ratchet, allowing the elastic potential energy stored in the energy storage device 2200 to be released. In normal energy storage mode, the pawl engages in the ratchet teeth, preventing the ratchet from reversing under the restoring force of the spiral spring energy storage mechanism 2230, thereby locking the stored elastic potential energy. When it is necessary to release the stored elastic potential energy to drive the vehicle, the pawl is disengaged from the ratchet teeth by operating the ratchet lock-up release mechanism. The ratchet is no longer subject to one-way lock constraint, and the elastic potential energy stored in the spiral spring energy storage mechanism 2230 can be released through the free rotation of the ratchet spring mechanism 2210. The ratchet lock-up release mechanism can be operated via an internal switch or handle within the vehicle 2000, allowing the driver to conveniently release the stored energy when needed.

[0043] A reduction gear mechanism 2220 is positioned between the ratchet spring mechanism 2210 and the spiral spring energy storage mechanism 2230, configured to reduce the speed and increase the torque of the input rotational motion before outputting it. Specifically, the reduction gear mechanism 2220 converts the higher speed, lower torque rotational motion input from the ratchet spring mechanism 2210 into a lower speed, higher torque rotational motion, which is then output to the spiral spring energy storage mechanism 2230. Since the force generated by the human body during rowing is relatively limited, and the spiral spring energy storage mechanism 2230 requires a large torque to be effectively wound, the reduction gear mechanism 2220 is needed to amplify the torque. For example, each time the user pulls, the ratchet spring mechanism 2210 rotates half a turn or one turn. After the transmission ratio conversion by the reduction gear mechanism 2220, the rotation reflected on the input shaft of the spiral spring energy storage mechanism 2230 may only be a few degrees, but the torque is significantly increased, sufficient to wind the spiral spring.

[0044] In optional embodiments, the reduction gear mechanism 2220 is configured as a multi-stage reduction gear mechanism or a multi-gear switchable reduction gear mechanism. A multi-stage reduction gear mechanism refers to a reduction gear system composed of multiple pairs of meshing gears connected in series, achieving a larger overall transmission ratio through multi-stage transmission, thereby obtaining a greater torque amplification factor. A multi-gear switchable reduction gear mechanism refers to a gear mechanism with multiple selectable transmission ratios, allowing the user to switch between different transmission ratios as needed. When the reduction gear mechanism 2220 is configured as a multi-gear switchable mechanism, it can cooperate with the aforementioned multi-gear resistance adjustment mechanism 2160: switching different transmission ratios changes the resistance level when the user pulls; the larger the transmission ratio, the greater the resistance. Specifically, the multi-gear switchable reduction gear mechanism may include multiple sets of gear pairs with different gear ratios and shifting mechanisms such as shift forks or synchronizers for switching between different gear pairs, its working principle being similar to the shifting principle of a car transmission. By employing a multi-stage or multi-gear reduction gear mechanism 2220, the energy storage device 2200 can adapt to the physical conditions and different exercise intensity requirements of different users, while ensuring that the spiral spring energy storage mechanism 2230 can be effectively wound up for energy storage.

[0045] The spiral spring energy storage mechanism 2230 is the core energy storage component of the energy storage device 2200. The spiral spring energy storage mechanism 2230 includes a spiral metal strip and is configured to store mechanical energy by converting it into elastic potential energy through winding. The working principle of the spiral spring energy storage mechanism 2230 is similar to the mainspring in a mechanical watch or the energy storage spring in a wind-up toy. Specifically, the spiral spring energy storage mechanism 2230 includes a long, thin metal strip made of a highly elastic metal material (such as spring steel), which is spirally wound around a central shaft to form a spiral spring. In its naturally relaxed state, the spiral spring is in an unfolded or semi-unfolded state. When a rotational torque is applied to the central shaft through the reduction gear mechanism 2220, the spiral spring is gradually wound tighter around the central shaft, causing the metal strip to elastically deform and store elastic potential energy. The tighter the spiral spring is wound, the greater the elastic potential energy stored within it. When the externally applied rotational torque is removed and the ratchet spring mechanism 2210 is locked, the spiral spring remains coiled under the constraint of the ratchet lock and does not release, thus storing elastic potential energy stably. The size and specifications of the spiral spring energy storage mechanism 2230 can be designed and optimized according to the energy storage requirements of the emergency propulsion device 1000 to ensure that it can store enough energy to drive the vehicle 2000 a certain distance.

[0046] In a preferred embodiment, the maximum energy storage limit of the energy storage device 2200 is configured to drive the vehicle 2000 at least tens to hundreds of meters. This maximum energy storage limit depends on factors such as the material properties and dimensional parameters of the spiral spring in the spiral spring energy storage mechanism 2230, and the transmission efficiency of the emergency power transmission system 2300. Through reasonable design, the energy storage device 2200 can accumulate sufficient elastic potential energy after the user engages in, for example, about half an hour of rowing, to drive the vehicle 2000 tens to hundreds of meters in an emergency, sufficient to push the vehicle 2000 to the nearest safe location.

[0047] The overall energy storage process of the energy storage device 2200 is as follows: The user pulls the rowing machine handle 2140, which, via the pull rope 2150, drives the ratchet of the ratchet spring mechanism 2210 to rotate by a preset angle. The rotation of the ratchet is then transmitted to the central shaft of the spiral spring energy storage mechanism 2230 after being reduced in speed and torque by the reduction gear mechanism 2220. The rotation of the central shaft further tightens the spiral spring, storing more elastic potential energy. After the user releases the rowing machine handle 2140, the ratchet remains in its current position under the locking action of the pawl, and the spiral spring remains in its current tightened state without releasing. When the user pulls the handle again, the ratchet continues to rotate in the same direction from the previous stopping position, further tightening the spiral spring. This process is repeated multiple times, gradually increasing the elastic potential energy accumulated in the spiral spring until the maximum energy storage limit is reached or the user stops moving.

[0048] like Figure 2 As schematically shown, an emergency power transmission system 2300 is disposed between the energy storage device 2200 and the wheels 2001 of the vehicle 2000. It is configured to release the elastic potential energy stored in the energy storage device 2200 and transfer it to the wheels 2001 to drive the vehicle 2000 when the vehicle 2000's power system fails or its power is depleted. The emergency power transmission system 2300 includes a clutch 2310, a transmission reduction gear mechanism 2320 with a differential, a drive shaft 2330, and a ball joint 2340.

[0049] The clutch 2310 is configured to be selectively engaged or disengaged via an operating mechanism within the vehicle 2000 to achieve power transmission or separation between the energy storage device 2200 and the wheels 2001. During normal driving or energy storage, the clutch 2310 is disengaged, and there is no power transmission connection between the energy storage device 2200 and the wheels 2001. The user's rowing motion is only used to store energy in the energy storage device 2200 and does not affect the normal driving of the vehicle 2000. In case of emergency propulsion, the driver operates an operating switch or handle within the vehicle 2000 to engage the clutch 2310, establishing a power transmission path between the energy storage device 2200 and the wheels 2001. The stored elastic potential energy can then be transmitted to the wheels 2001 through the emergency power transmission system 2300.

[0050] In a preferred embodiment, the clutch 2310 is disposed on both sides of the transmission path of the emergency power transmission system 2300. Specifically, as Figure 2 As schematically shown, two clutches 2310 are arranged in the transmission path from the energy storage device 2200 to the wheel 2001. When both clutches 2310 are disengaged, the energy storage device 2200 is completely separated from the wheel 2001, and there is no mechanical connection between them. This dual-clutch design ensures that under normal driving conditions, the transmission components in the emergency power transmission system 2300 are not disturbed by the rotational force from the wheel 2001, thereby protecting the components from unnecessary wear. During emergency propulsion, both clutches 2310 are engaged, forming a complete transmission path from the energy storage device 2200 to the wheel 2001.

[0051] The transmission reduction gear mechanism 2320 with differential is configured to distribute the released mechanical energy to the left and right wheels 2001 of the vehicle 2000 after reduction and torque amplification via the differential. Specifically, when the spiral spring energy storage mechanism 2230 releases elastic potential energy, the spiral spring rebounds and drives the central shaft to rotate at high speed. This high-speed rotation is transmitted to the transmission reduction gear mechanism 2320 through the transmission path and is further reduced and amplified to ensure that the torque output to the wheels 2001 is large enough and the speed is appropriately low, so as to effectively drive the vehicle 2000 to move slowly. The differential included in the transmission reduction gear mechanism 2320 distributes the output torque to the left and right wheels 2001 of the vehicle 2000, so that the vehicle 2000 can achieve differential rotation of the left and right wheels when turning or when one wheel encounters different resistance, ensuring the normal driving of the vehicle 2000.

[0052] Driveshaft 2330 and CV joint 2340 are configured to transmit power from transmission reduction gear mechanism 2320 to wheel 2001. Specifically, driveshaft 2330 extends from the differential output end of transmission reduction gear mechanism 2320 to wheel 2001. Because wheel 2001 has variations in suspension travel and steering angle relative to the vehicle body, driveshaft 2330 and wheel 2001 need to be connected via CV joint 2340 to accommodate the continuous changes in angle between driveshaft 2330 and wheel 2001. CV joint 2340 can transmit rotational power at a constant speed even with changes in transmission angle, ensuring smooth and continuous power transmission during vehicle 2000 operation.

[0053] In a preferred embodiment, wheel 2001 is the front wheel of vehicle 2000. The arrangement of outputting power from emergency power transmission system 2300 to the front wheel is suitable for front-wheel drive vehicles, and the front wheel is located at the front of vehicle 2000, which is close to the energy storage device 2200, which is usually located in the engine compartment area at the front of vehicle 2000. This helps to shorten the transmission path and simplify the transmission structure.

[0054] In a preferred embodiment, the emergency power transmission system 2300 is configured as a rigid transmission connection from the energy storage device 2200 to the wheel 2001. A rigid transmission connection means that after the clutch 2310 is engaged, the entire transmission path from the energy storage device 2200 to the wheel 2001 is composed of rigid mechanical components (gears, shafts, universal joints, etc.), without any elastic or hydraulic components that can absorb or dissipate energy. This rigid transmission connection ensures that when the vehicle 2000's braking system brakes the wheel 2001, the wheel 2001 is held in place by the brake pads and stops rotating. Due to the rigidity of the transmission path, the coiled spring in the energy storage device 2200, rigidly connected to the wheel 2001, also stops releasing and remains in its current coiled state, preventing the loss of elastic potential energy. In other words, the driver can stop the vehicle 2000 at any time by pressing the brake pedal without wasting any stored elastic potential energy. When the driver releases the brake pedal, wheel 2001 is no longer held, and the spiral spring continues to release elastic potential energy to drive wheel 2001 to rotate, allowing vehicle 2000 to continue moving. This rigid transmission connection design allows the driver to flexibly control the speed and stopping point of vehicle 2000 through the braking system, similar to controlling vehicle speed by braking while idling, while ensuring that valuable stored energy is not wasted due to braking.

[0055] The overall power transmission process of the emergency power transmission system 2300 is as follows: When the power system of the vehicle 2000 fails or the power is exhausted, the driver engages the clutches 2310 on both sides of the transmission path through the operating mechanism inside the vehicle 2000 to establish a power transmission path from the energy storage device 2200 to the wheels 2001; then, the ratchet lock release mechanism is operated to release the one-way lock of the ratchet spring mechanism 2210, and the scroll spring in the scroll spring energy storage mechanism 2230 rebounds under the action of elastic restoring force, driving the central shaft to rotate; this rotational motion passes through the reverse transmission of the reduction gear mechanism 2220 (at this time, the reduction gear mechanism 2220 works as a speed-increasing and torque-reducing mechanism), the ratchet spring mechanism 2210, the transmission reduction gear mechanism 2320 (which further reduces the speed and increases the torque of the high-speed rotation released by the scroll spring), and its differential distribution, and is then transmitted to the left and right front wheels 2001 of the vehicle 2000 through the drive shaft 2330, the clutch 2310 and the ball joint 2340, driving the vehicle 2000 to move forward slowly. During this process, the driver can stop or slow down the movement of vehicle 2000 at any time by pressing the brake pedal. The elastic potential energy is not consumed when braking. After releasing the brake, vehicle 2000 continues to move until the elastic potential energy in the spiral spring is completely released or vehicle 2000 reaches the target position.

[0056] Figure 3 A schematic flowchart illustrating a method 3000 for using an emergency propulsion device 1000 according to an embodiment of the present invention is shown. Figure 3 As shown, the method 3000 includes steps S100 and S200.

[0057] In step S100, rowing motion is performed using the rowing machine device 2100, allowing the energy storage device 2200 to store mechanical energy in the form of elastic potential energy. Specifically, the user sits on the driver's seat platform 2110, unlocks the slide rail locking device 2130, and repeatedly pulls the rowing machine handle 2140 to perform rowing motion. Each pull causes the ratchet of the ratchet spring mechanism 2210 to rotate by a preset angle via the pull rope 2150. The rotation of the ratchet is then transmitted to the spiral spring energy storage mechanism 2230 after being reduced in speed and increased in torque by the reduction gear mechanism 2220, causing the spiral spring to further tighten and converting the mechanical energy generated by the rowing motion into elastic potential energy for storage. The user can continue rowing motion according to their own fitness needs, such as rowing for about half an hour, during which the elastic potential energy gradually accumulates and increases. Step S100 satisfies the user's exercise and fitness needs while also storing mechanical energy, achieving a dual benefit.

[0058] In step S100, the user can select an appropriate resistance level based on their physical condition using the multi-level resistance adjustment mechanism 2160 to achieve a comfortable exercise experience. Simultaneously, during the execution of step S100, when the energy storage device 2200 reaches its maximum energy storage limit (i.e., the spiral spring has been wound to its limit and cannot be wound any further), the user can release some of the stored elastic potential energy by engaging the emergency power transmission system 2300, allowing the vehicle 2000 to move a certain distance. Afterward, the user can disengage the emergency power transmission system 2300 and continue rowing to re-store energy. In this way, even when the spiral spring reaches its energy storage limit, the user can continue rowing without restriction, while simultaneously releasing excess energy through vehicle movement.

[0059] In step S200, when the power system of the vehicle 2000 fails or is depleted, the emergency power transmission system 2300 is engaged and the elastic potential energy stored in the energy storage device 2200 is released to drive the wheels 2001 of the vehicle 2000 to rotate. Specifically, when the vehicle 2000 cannot drive normally due to battery depletion, power system failure, or other reasons, the driver can engage the clutches 2310 on both sides of the transmission path through the operating switch or handle inside the vehicle 2000 to establish a power transmission path from the energy storage device 2200 to the wheels 2001; then, the ratchet lock release mechanism is operated to release the one-way lock of the ratchet spring mechanism 2210, and the spiral spring rebounds under the action of elastic restoring force to release elastic potential energy, which is transmitted to the wheels 2001 through the emergency power transmission system 2300 to drive the vehicle 2000 to move.

[0060] In step S200, the driver can control the speed of vehicle 2000 through the braking system. Specifically, the driver can decelerate or stop vehicle 2000 at any time by pressing the brake pedal. Due to the rigid transmission connection of the emergency power transmission system 2300, the spiral spring stops releasing energy during braking and is not wasted; after releasing the brake, vehicle 2000 continues to move. The driver can precisely control the speed and distance of vehicle 2000 by repeatedly pressing and releasing the brake pedal, just like normal idling driving, to safely move vehicle 2000 to the nearest charging station, repair shop, or other safe location.

[0061] In another embodiment, a confirmation step may be included before step S200 to confirm that elastic potential energy is stored in the energy storage device 2200. This confirmation step ensures that the driver is aware that usable elastic potential energy is indeed present in the energy storage device 2200 before performing an emergency propulsion operation, avoiding accidental operation when there is no stored energy. Confirmation can be made, for example, by viewing the current stored energy through an energy storage status indicator on the vehicle 2000's dashboard, or by using other appropriate indicators to inform the driver of the current energy storage status.

[0062] In embodiments not specifically shown, the steps mentioned above may also be combined with each other in the same usage method 3000. For example, the operation of releasing part of the energy when the maximum energy storage limit is reached in step S100, the energy storage confirmation step before step S200, and the braking control vehicle speed step in step S200 may be used in the same usage method 3000.

[0063] Although specific embodiments of the invention have been described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of the invention. Various substitutions, alterations, and modifications can be conceived without departing from the spirit and scope of the invention.
