These wheels run on the road 480 and support the small turbine treadle pedal 488, which in turn rides the rider. A steering shaft 484 connects the handlebar 24 to the front shaft 526 via a support bearing 494, a folding bearing 498, and a tilt bearing 50.2. The front rolling bearing 5 06 and the rear rolling bearing 5 14 determine how the rider pedal 488 is tilted. A support 492 is folded and adjusted by means of one or more support bearings 494, a support adjustment bearing 522, and a lower support bearing 510. Each bearing makes the movement mainly around X, Y, and some combination of the Z-axis represented by coordinates 501, where the X direction refers to the direction in which the small treadmill moves forward. An optional flexible bearing 485 allows the handlebar to be folded towards the seated rider at a comfortable fixed angle or rigidly held in a straight position.

V. Description of Invention (26) Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs The axis is free to rotate. Tough and highly elastic tire surface 562 provides low rolling resistance on hard roads. The fork carriage 542 is slidable within the steering shaft 546 and is separated by a spring and a shock absorber assembly 550, which separates the steering shaft from the front wheel road vibrations. Front wheel road vibrations are separated from the rider by the flexibility of the lever arm formed by the front pedals 1 54 and any of the shock absorbers at the joint 1 59 (see Figure 16). Figures 28A and 28B show two states of a mechanism that makes it easier for small wheels that facilitate close folding to pass obstacles such as curbs or potholes. Figure 28 shows an appliance on the front wheel of a small turbine treadmill, although any wheel can be modified in this way. A wheel 564 is supported on a shaft 568 by a wheel fork 576, which is rotatable backward on a suspension shaft 580 supported by a steering shaft 584. The pedal 586 of the small turbine treadmill is connected to the steering shaft by a spherical bearing 590 (usually concealed). When the wheel 564 sinks along the road 572—an obstacle 598 that normally stops the car, a spring 598 or a bending spring 602 is forced to bend, allowing the wheel fork 576 to rotate backward about the suspension shaft 580, forcing The small wheel 606 leans down on the upper surface 620 of the obstacle 594. In some cases, pressing the height of the obstacle 594 also raises the pedal 586. After the front suspension device is in the folded state shown in FIG. 28B, the rider moves the handlebar back to restore the device to its original state. At this time, the downward force on the shaft 580 is greatly reduced so that these springs 602 and 598 with stress Turn the fork 576 to its normal position. The bending spring 602 is supported at its upper end by a steering shaft 584, and its lower end is fixed to a wheel fork 576.

Economy. Printed by the Consumers' Cooperative of the Central Bureau of Standards and Assistance. 5. Description of the invention (27) The horizontally curved wheel allows the fork 576 to turn normally. In the normal position, the static force exerted by the springs 602 and 5 98 (FIG. 28A) can be reduced by placing the wheel shaft 586 in front of the suspension shaft 580, as shown by lines 614 and 618. After this configuration, the weight of the rider and the car itself will be downwards.... It will help to keep the wheel in its normal position when it is added to the suspension shaft 580. When necessary, additional forward force is provided to the fork 576. The backward force acting on the wheels 564 and fork 576 by the road 572 is generally harmless and can be overcome by the springs 602 and 598. As far as the shaft 568 is behind the suspension shaft 580 (closer to the rear of the small motorcycle treadmill), the springs 602 and 598 act like a conventional trailing arm suspension, thereby reducing the effect of road vibration on the pedal 586. In this state, an additional force must be applied by either or both of the springs 602 and 598 to compensate the weight of the rider or the vehicle. The shaft 610 of the small wheel 606 may be fixed to the steering shaft 584 or the pedal 586 instead of the wheel fork 576. For the front and rear of small electric motorized treadmills, in order to reduce rolling friction, it is best to use non-inflatable (low-energy, wear-resistant, elastic material) wheels. Fig. 29 is a side view of an adjustable suspension and braking device for the rear wheel 688 of a small-turbine treadmill (shown in a schematic view). The rear wheel 688 rotates on a shaft 680 and is supported by a drag arm 640, which pivots on one end of a torsion bar 636, and the other end is rigidly mounted on a suspension arm 644. The gear box 448 and the motor 432 of FIG. 23 may be optionally incorporated in the trailing arm 640. The maximum extension of the trailing arm is limited by an optional adjustable stop 698, which is mounted on the bracket 668, which in turn is fixed on the pedal 624. The minimum extension of the trailing arm is limited by a shock-absorbing impact stop 698. -30- This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling in this (Page) ®, Book a bed.

The preload pressure of the adjustable spring 684 is changed by rotating it around its threaded core. The adjustable springs 684 may be alternately gradual, and their elastic constants will increase appropriately with pressure, which will allow a heavier rider to a lighter rider to experience a stronger average spring constant, although its average spring compression is larger. Moreover, in some embodiments, the spring 684 is equipped with energy dissipating elements to reduce spring resonance effects. Either the torsion spring 636 and the adjustable spring 684, or both, with or without other known suspension mechanisms, can optionally be used to provide the required suspension performance. The illustrated adjustable spring 684 is provided in series with a pressure sensor 687 that measures the weight of the rider. The taillight 689 provides rider safety at night and also functions as a brake light. -Pedal load sensors (such as pressure sensors 653 or 687) enable the motor controller to prevent the use of the small turbine treadmill when the rider's weight is too large for the product or rider's safety; for example, when the perceived load has exceeded- 31- This paper size is applicable to the national standard (CNS) A4 specification (210X297 mm) A7 B7 _ V.

This reasonable minimum weight should be set fairly low (and / or fairly long as defined above) so that the rider can partially move his or her weight onto the road and start the car with one foot Without triggering the function of automatic braking.

When a rider steps on a brake pedal 620, the brake mechanism presses the brake pads onto the rear wheel 688. The brake pedal is generally provided on the rear edge of the rider pedal 624. A brake arm 660 is A brake shaft 664 fixed on the bracket 668 is supported. When the brake pedal 620 is depressed, the brake arm 660 rotates backward and forces a brake pad 696 to press Wheel 688. As shown in the figure, the brake pad 672 is also pressed against the wheel 688 by a rotating arm 694 that rotates around the shaft 692. The load is formed by a pin 656 on the brake arm 660, and the pin is tight at this time. Press and slide the swivel arm 694. The two braking devices shown can be used independently or in combination. The mechanical benefits between the relative displacement of the brake pedal 620 and the brake pads 696 and 672 are dictated by their participation The size is determined. The mechanical benefit is around 0.5 to 4 which is suitable for most riders who can apply most of their weight to the gj brake pedal. Seated riders generally prefer higher mechanical benefits because they require less "In general, the brake pad 672 is best approached from the side at the level of the axle 680. -32- This paper size applies to the Chinese National Standard (CNS) A4 specification (210X297 mm) ) B7 V. Invention description (30) Wheel 688, so that the rail pads will not significantly interfere with the normal vertical movement of the wheels allowed by the suspension system. Power brakes (not shown) are used for weak rides A hand with an electromechanical transmission. Figures 30 and 31 show an improved skateboard that is placed in front of any wheel to help lift the wheel over obstacles such as curbs or potholes on the road. The The skateboard includes a rotatable transmission belt 704 that reduces the chance of vehicle damage due to sliding contact with obstacles. The presence of a transmission belt also reduces the amount of maximum load transferred to the frame because a portion of the contact energy is converted into elastic deformation And drive system kinetic energy. The transmission belt 704 is extremely easy to replace compared to the more expensive structural chassis components. When an obstacle hits the bottom surface of the slidable transmission belt 704, it is transmitted to the transmission belt bracket 702 through the transmission belt 704 and thus to the vehicle The load of structure 700 pushes the wheels upwards. A drive belt 704 surrounds a front roller 706 and a drive belt bracket 702, and leaves some sag on the drive belt to form a curve 708 behind the slide. The transmission belt 704 is free to rotate through the transmission belt bracket 702, which provides a slippery surface to the inner surface of the sliding belt 704. The roller 706 also reduces the friction that often prevents the belt 704 from rotating, and it can be rigidly fixed.

More than two rollers (or the belt support between the rollers) can be used, and even if the bottom surface of the skateboard is not too inclined with respect to the horizontal, even the sliding belt 716 can be omitted.

Description of the invention (35)-The adaptive controller 784 provides an integrator (not shown) in the external motion pi controller 788, its constant KjQKi, and an anti-distortion limit 値. The anti-distortion limit 値 is a threshold 而且, and if% exceeds this threshold, the integrator will no longer perform integration operations (ie, the integrator is boxed). The output of the external motion PI controller 788 passes a torque limiter 790, which is cut off when the torque signal exceeds a (reasonable) setting by the adaptive controller 784. The adaptive controller 784 derives this from the temperature and speed of the motor and the state and charging of the battery pack 746. The output of the torque limiter 790 is linearized by a linearizer 796 (in other words, the linearizer 796 eliminates any non-linear relationship between motor torque and current). The specific function is matched to the motor by the specific function used by the linearizer 796 and adjusted by the adaptation controller 784 in response to the motor variable. The adaptation controller 784 periodically adjusts the linearizer 796 according to the motor temperature. The output of the linearizer 796 is the required horizontal current (It) required to generate the required torque (Tt) by the motor 750. The actual current obtained by the battery pack 746, the DC-DC converter 801, and the motor driver subsystem 802 is 813b, A subtractor 813 compares this with the required current 値 813a and sends its difference to a current PI controller 798.

The output of the current PI controller 798 is sent to and controls the DC-to-DC converter 801, controls the current of the motor driver subsystem 802, and therefore also controls the torque of the motor 750.

Description of the Invention (36) The low-pass filter library 806 and a sign function 804 receive the signal. The sign function supplies the conversion logic 808 with information on the required torque (Tt) sign, and the shaft encoder 810 supplies the conversion logic 808 with the actual condition of the motor 750. The low-pass filter bank 806 supplies the conversion logic 808 at the actual speed of the motor 750. This information enables the conversion logic to properly use the motor driver subsystem 802 to drive the three phases of the motor 750. The shaft encoder 810 also supplies the adaptation controller 784 and the low-pass filter bank 806 with the condition information of the motor 750. The low-pass filter library 806 uses the condition of the motor 750 to estimate the speed of the motor 750, and estimates the condition of the motor rotor and the actual torque, to estimate the speed of the motor 750 to produce a smooth condition of the motor 750, and estimates the condition of the motor rotor and the actual Torque to produce a smooth motor 750 condition, speed, acceleration, and torque estimates (and therefore the speed of the small turbine treadmill). These actual performance estimates are subtracted by the subtractor 794 from the newly required performance characteristics (in other words, torque, angular velocity, acceleration) in the next clock cycle. The adaptive controller 784 controls the functions of the entire low-level control mechanism 772 by relying on the rider sensor 742 and the temperature sensor 814, and appropriately controls the torque limiter 790, the linearizer 796, the low-pass filter bank 806, and the PI controller. 788 and 798 estimate actual motor torque, condition, acceleration, battery charge, and output estimates. Proper control of these system adjustment mechanisms indicates that motor and battery changes are caused by changes in temperature, mechanical load, and manufacturing errors. The adaptive controller 784 implements speed limitation and conversion of small turbine treadmill operating conditions, and adjusts other application controllers, such as gradually increasing scheduling for a given set of estimated motor, battery, and load parameters. In addition, the adaptive controller 784 passes the actual motor torque, acceleration, and speed data through the line -39- This paper size applies the Chinese National Standard (CNS) A4 specification (2i × 297mm) (Please read the precautions on the back before filling in this page)

The invention description (37) 786 was sent to the senior control agency 764. The temperature sensor 814 includes a motor temperature sensor, a power electronics temperature sensor, a battery pack temperature sensor, and an external (i.e., ambient) temperature sensor. If the motor, power electronics, or battery pack becomes too hot, it could be damaged or rendered useless. Similarly, a permanent magnet motor will be invalidated if the permanent magnet is too cold. The adaptation controller 784 notifies the advanced control mechanism 764 of an impending fault condition, such as that the temperature is increasing or decreasing, and the advanced control mechanism 764 notifies the rider via the rider indicator 736. Referring to FIG. 36, the battery pack 746 supplies power to the drive motor 750 through a DC-to-DC converter 801 (e.g., a voltage-to-current converter). By adapting the appropriate control of the current conversion ratio by the controller 784, the DC-to-DC converter 801 controls the amount of current in the motor drive subsystem 802 through the motor drive circuits of the A-phase 824, B-phase 825, and C-phase 826. The current sensor 828 is supplied to the low-level control mechanism 772 to estimate the torque of the motor at this time because it provides an estimate of the current through the motor. Because T = (Κτ) * (Ι) where 1 = the current delivered to the motor by a current sensor, and κτ = a known constant, which generally depends on the motor temperature. This measurement provides an accurate estimate of the motor torque (T) . Moreover, since the conversion ratio used by the DC-to-DC converter 801 at any period is known, the data measured by the current sensor 828 is supplied to the adaptive controller 784 to obtain an accurate estimate of the current from the battery pack 746. The voltage sensor 820 is supplied to the adaptation controller 784 on the direct measurement side of the battery pack 746 voltage. • 40- This paper size is in accordance with Chinese National Standard (CNS) A4 specification (210X297 mm) (Please read the notes on the back before filling this page) j β * 1Τ Printed by the Consumers' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs A7 B7 V. Description of the Invention (38) Referring to FIG. 35, in order to operate the brushless motor 750, the motor driving circuits 824, 825, and 826 send electric pulses to the motor 750 synchronized with its state (in other words, timing). As mentioned before, the status is determined by the shaft encoder 8-10. Using this information, the conversion logic 808 drives the motor drive circuits 824, 825, and 826 to supply the motor 750 with accurate timed electrical pulses. An in-depth discussion of proper motor operation can be found in W, Leonhard, Control of Electrical Drives (Springer, 1985, Berlin, Germany) and B.K_Bose. Power Electronics and AC Drives (Prentice Hall, 1 986, Englewood Cliffs, New Trans. West). Referring to FIG. 37, in order to express the characteristics of a specific working condition theorem (for example, the mathematical form of the theorem is a polynomial, a piecewise linear equation, or a lookup table compiled by the controller 730 in FIG. 33), a graph is used to Indicates that the required acceleration (oct) is sent from the high-level control mechanism 764 (Figure 34) to the low-level control mechanism 772, which is related to the actual estimated pedaling speed (V) of the small turbine, and is related to a selected acceleration measurement parameter Q, Q When it is positive, it means acceleration, and when it is negative, it means braking. For example, Q is located between +1 値 and -1 ，, which corresponds to the stress state of the sensor located in FIG. 21 corresponding to the acceleration lever 3 1 8 and the brake lever 314. As shown in the figure, for any particular Q 最高, the maximum allowable acceleration slowly decreases to allowable negative acceleration as the speed V increases. Safety often requires that the acceleration be reduced when the treadmill speed of the small turbine is increased, while equipment considerations generally require that the motor be powered with the motor and that the allowed acceleration and motor current be reduced when the temperature of the electronic device increases. When the rider presses the accelerometer to the maximum forward (Q = 1) position, if the speed of the small turbine treadmill is negative, the maximum safe forward acceleration is -41-This paper standard applies to Chinese National Standard (CNS) A4 Specifications (210X297 mm) (Please read the notes on the back before filling out this page)-° Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs A7 __'_ ^ _ B7__ V. Description of the invention (39) Possible. As the speed increases to the limit speed (¥ „_), the allowable acceleration is reduced to zero. This is because when the speed exceeds this limit speed, the high-level control mechanism 764 sends to the low-level control mechanism 772—a negative acceleration command, which causes the motor The 750 provides reverse torque to the rear axle of the small turbine treadmill to slow down or brake the rear wheels or double rear wheels. The control theorem can be modified to reflect the rider's skill or road conditions (vmajaamax is variable). For example, if the torque of the motor The change is continuous beer instability, you can temporarily reduce Vmax, which indicates that the road is bad or the rider is unskilled. If the speed or torque change of the motor becomes very unstable after a large acceleration, you can temporarily change% ^ In addition, according to the skill or preference of the rider, when the small turbine treadmill is at a standstill or the speed of movement is slow, a greater accelerator pressure is required to achieve a given acceleration in order to avoid the sudden or unnoticed Accidents caused by forward motion. This requirement can be achieved by the non-linear relationship between Q and α, such as by setting A quiet zone, where at is close to zero. The more unstable small turbine treadmill operation can be solved by adding to the low sensitive quiet zone. The maximum allowable speed Vmax can also be set so that it depends on the rider's The total weight, in addition Vmax is equal to zero is lower than some of the lowest min equivalents — unloaded scooter treadmills, or equivalent to underweight toddlers to use the device safely. Similarly, if the rider ’s weight exceeds a maximum min値 For example, 275 pounds, 乂 ^ can be set to zero to prevent the motor from overloading.

If the program passes a test step 842, the weight sensor 653 or 687 (Figure 29) is checked in test step 844. To determine if the rider weight on the small-wheeled bike exceeds some minimum 値 (for example, 30 pounds). If so, the controller 730 will read these sensors and control the state parameters 値 according to the current set in step 870 in advance, Or, according to the missing parameter 値, control the motor 750 and the rider indicator 736. If the small turbine treadmill has not been loaded in test step 844 for more than T seconds, a test step 848 will determine whether the accelerator 77 or brake 76 is Operated by the rider; if not, the rider may not be on the car, so the controller 730 controls the braking torque in the motor 750.

Furthermore, the three-section steering column shown in FIG. 16 has been replaced by one or two section steering columns 902 in FIG. 39. The steering column 902 is composed of an upper column 904 and a lower column 906. In this embodiment, the upper pillar 904 includes two parallel pillars 903a and 903b, but it may be a single member as shown in FIG. The upper post 904 is slidably disposed relative to the lower post 906, and sliding is controlled by a separate latch 916. Separate control of the latch 91 6 allows the chassis of the small turbine treadmill to be folded around the hinge 914 without the handlebars being fully retracted (for example, for ease of dragging). For carrying, the chassis can be folded around the hinge 914 while the steering column is fully retracted. In addition, a separate latch 916 allows riders to adjust the height of the handlebars for comfort. In this embodiment, the spherical bearing 220 of FIG. 16 is replaced by three separate bearings, similar to the configuration shown in FIG. 1 ^ The handlebar 24 of FIG. 39 is mounted on the upper steering column 904 via a handle attachment 908 on. The handle attachment 908 staggers the handlebar 24 and the steering column 902. In order to turn the steering column to a certain amount, the rider must make a large amount of movement on the handlebar, thereby increasing stability. Fig. 40 shows the embodiment of Fig. 39 in a half-folded configuration. Note that the sliding support 900 is all configured in the channel 910 as shown. The handlebar 24 has a steering handle 918 and a handlebar 920. Steering handles 91 8 are used to drive small turbines-45- This paper size applies to China National Standard (CNS) A4 (210X25 »7 mm) (Please read the precautions on the back before filling this page) " installation .

Description of the invention (43) When steering the bicycle, it is set away from the steering column so as to easily apply steering torque to the steering column. The handle 920 is used when towing or carrying a small turbine treadmill 'and is disposed closer to the steering column so as not to cause a large torque around the steering column. The handles 918 and 920 are composed of a U-shaped handle attachment 908 and a handlebar 24 (FIG. 39). For more comfort, the handle 918 and the handle 920 can also be made into separate shapes or added with a handle cover. Fig. 41 shows the fully folded shape of the embodiment of Figs. In this illustration, the distance between the handle 920 and the rider ’s force on the folding small bike treadmill can be reduced to a minimum, making it more comfortable to carry, which helps prevent unintentional twisting (for example, this can lead to small folding The turbine treadmill is deflected into the rider's legs when carried). In addition, staggering the handlebar 24 with the steering column 920 helps to provide comfortable carrying, by placing the handle 920 above the center of gravity 922 of the folding envelope. This method of placing the handle on the center of gravity provides good control of the folding envelope being carried, and allows the component to be vertically downward when held, thereby allowing the rider to get closer when holding the component.

Description of the invention (44) Drive one front wheel 12 and one rear wheel 8, or drive front axle 224 and / or rear axle (or Double rear axle) 452. Various transmissions 448 (Figure 23) can be used, including direct drive, drive belt, hydraulic transmission, or a differential (similar to those used in automobiles). These can have a single gear ratio or multiple gear ratios, and these gear ratios can be converted manually or by a command from the controller. In addition to the external computer input / output port 726 (Figure 33) and recharging port 744, the power output can be provided with an additional external output port 748, in order to use the energy of the small turbine treadmill to generate various power signals to drive external devices that may not be connected For example, a lamp 401 (Figure 22). Temperature Although various temperature sensors 814 shown in Fig. 35 are replaceable, the temperature can also be derived from the operating conditions of the motor. Using the voltage applied to the motor 750 measured by the voltage sensor 820 (Figure 36) and applying knowledge about the relationship between the feedback electromotive force, the motor speed, and the current through the motor measured by the current sensor 828, the motor windings can be determined The resistance. Generally, the motor winding is made of copper, and the relationship between temperature and resistance is preset. In this way, when the resistance of the copper winding is known, the temperature of the winding can be estimated. The temperature of the critical electronic component can also be estimated by measuring the ambient temperature and supplementing the thermal calculation model. The model calculates the time-weighted effect of heat dissipation by I2 * R, where I is the current through the heated component, and R is Its resistance. Similarly, the battery temperature can be estimated as a function of the duration of the current. -47- ^ Zhang scale is applicable to China National Standard (CNS) A4 specification (210 '乂 297mm)': (Please read the precautions on the back before filling this page)

Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the invention (45) Sensor configuration and replacement of the weight sensor 653 shown in Figure 29 can be set in various positions, including, for example, on the pedal 4 (Figure 10). Another alternative to the weight sensor is a pressure sensor 687, which withstands the force applied by an adjustable spring 684 (Figure 29). In addition, the small bicycle tread position sensor 23 9 (FIG. 18) allows the rider to change its shape when the small bicycle treadmill is folded or carried with the handlebar 24 or the hinge 166 (FIG. 18). This eliminates the need for an on-off switch, and the rider can send the required working status signal to activate the position sensor or pressure sensor 653 by a series of preset small turbine treadmill movements. Because different riders have different amounts of impulse to the sensor, and because sensor readings may change, in some embodiments, the controller 774 (FIG. 34) includes an automatic sensor recalibration mechanism. Recalibration is based on the range of sensors observed during normal use, or on the basis of a rider's plan to carefully limit the number of critical sensors beyond their required power range. Motorized wheels are locked in a “wheel locked” state, the controller 774 is optionally set to make the motor 750, in order to prevent the wheel from moving, apply reverse or forward torque to one or more wheels as required . Mechanical locking, of course, the advantage is that it does not consume electricity. One of the ways to limit the rider's consumption of battery for stability is to limit the stable torque greatly.

These start signals may include: pressure on the accelerator 77 or the brake 76; jumping, this action reduces the weight on the small turbine treadmill to a predetermined value値 Stomp one or two times on the treadmill treadmill pedal; keep the treadmill treadmill toward a special orientation for a preset period of time; push backward; speed is greater than a preset threshold 値: start an approved braking effect; on the ground Slam the small turbine treadmill while using an accelerometer to verify the action (for example, two slams at the correct interval can cause movement); tap in the prescribed manner as sensed by sensor 653 or 687 (Figure 29) Scooter treadmill. Rider indicator Rider indicator 736 (Figure 34) can include many devices, including simple indicator lights, acoustic signals, and LCD display. Useful indicators issued by the controller 774 include battery voltage and charging status, Approximate driving range of small turbine treadmills under effective power, low power warning signals, morphological status, small turbine treadmill speeds, and multi-function indicators, etc. One or more lights can be used at night (for example, headlight 401) to illuminate the road in front of the small motorcycle treadmill and • 49 · This paper size applies to China National Standard (CNS) Α4 specification (210 × 297 mm) ~ (read First read the precautions on the back before filling in this 萸) clothing. -111 Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 V. Invention Description (47) As a warning to motorcyclists in front or behind and others (such as Combined with the tail light 689). One or more light sources can be connected to the power electronic board, and the light guide can be used to direct the desired direction and the liquid crystal or other optical switch can be used to modulate and eliminate the wires, so that one light can do several tasks. Observation Rider Technology Book Fapon's embodiment control system allows the speed limit to be set on the drive motor, and depends on the rider's observation braking technology, that is, the higher technology approved higher speed limit. For example, braking technology can be determined by observing the stopping distance of the rider at various speeds, that is, the shorter stopping distance and the smoother deceleration operation grant the rider a higher allowable speed. Cooling power dissipation is generally the largest among battery packs and motors. This high power dissipation requires cooling, including conduction, injection, and liquid convection, depending on the vehicle's construction and usage conditions. When the temperature sensor indicates that the temperature has reached a critical level, the controller can also forcefully reduce the load. Rechargeable batteries The life and performance of rechargeable batteries can be maximized by the correct charging scheme. These solutions can be implemented quickly by the controller. The battery charging status can be estimated by measuring the impedance of the battery controlled by the computer using the power electronics circuit. According to the number of days of use of the scooter treadmill and the usage pattern experienced, a more appropriate compromise can also be found between the speed of charging -50-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ) (Read the precautions on the back before filling in this page) ------------------- Order ------- ^-Consumption by Employees of Central Bureau of Standards, Ministry of Economic Affairs Cooperative Du printed A7 ______B7______ V.
