Description

Bicycle automatic damping adjustment method and device

The invention relates to a bicycle damping adjustment method, in particular to an automatic bicycle damping adjustment method performed by detecting information of a tire pressure or a strain gauge.

In recent years, as environmental awareness has gradually received the attention of the public, the number of people using bicycles has increased dramatically. Bicycles can not only become a means of transportation to work, reduce the amount of carbon dioxide emissions, but also achieve the effect of exercise and pressure.

Currently, bicycles that are commercially available are usually provided with shock absorbers to cushion the vibration caused by the unevenness of the road surface, and to keep the wheels in contact with the road surface when driving different road surfaces.

Currently, commercially available adjustable damping shock absorbers are manually adjusted and are usually placed at the front fork of the bicycle. The bicycle rider must stop and manually adjust the damping to the front wheel. In addition to this, there is also a damping adjustment switch that is placed at the handlebar, but the damping adjustment switch can only turn off the suspension effect, or restore the suspension effect, and the damping adjustment cannot be performed.

Generally, road-type bicycles do not have shock absorbers installed, and the tire pressure used is higher because road-type bicycles need to transmit all the knight's power to the acceleration, that is, to avoid any loss of acceleration caused by the state of power loss. For example, the compression of the shock absorber and the tire will make The loss of the power transmitted by the knight.

In general, off-road bicycles are equipped with shock absorbers, and tires with a large contact area and low tire pressure can be used to achieve complete contact between the tire and the ground, avoiding any slippage caused by road conditions. It is said that gravel road conditions or bouncing road conditions are likely to cause the bicycle to slip.

Among them, off-road bicycles are divided into many types, such as:

First, the Cross Country (XC), mainly riding on the rugged mountain road and gravel road.

Second, free ride (Freeride, FR), climb the mountain and climb through the extreme terrain mountain bike.

Third, downhill (Downhill, DH), with the most sturdy body, the thickest tires, equipped with high-performance shock absorbers, can sprint high-speed downhill on the hillside and carry out extreme sports.

Among them, Suspension is the device used to avoid (subtract) shock in most vehicles. The general design is a combination of spring, shock absorber and mechanical structure. The effect of the suspension is achieved by the flow of gas or liquid.

The suspensions commonly found in the bicycle field can be subdivided into a Suspension Fork, a Rear Shock, a Seat Post Shock, etc., in order to achieve the following objectives:

1. Carrying the static weight of the vehicle, controlling the distance between the car body and the road surface.

Second, reduce the situation of the tire jumping off the ground, keep the friction between the tire and the road surface to maximize, and increase the safety of the bicycle.

Third, provide good steering stability treatment, reduce the vibration of the body and the loss of steering, and provide the rider with the best handling.

Fourth, improve the rider's comfort, can eliminate the impact of bumpy roads on the car body and the rider.

For the mountaineering bicycle as a tool for rest, exercise and travel, the passive suspension device provided on the bicycle is sufficient to provide the basic comfort riding function. However, the damping provided by the general suspension can not meet the advanced requirements of riding rough roads when engaging in high-intensity activities such as off-road, and it is impossible to reach the extreme sports bike players in the competition. The performance necessary for ride control, safety and racing.

In order to adapt the bicycle to more different road conditions and operating conditions, in recent years manufacturers have developed a number of semi-active suspension design, the rider can manually adjust according to the comfort and handling needs. On the other hand, suspension is not entirely an advantage for bicycles. Shock absorbers can offset the vibration from the road surface, and relatively offset the rider's pedaling force.

There is no competitive road bike equipped with a suspension device. The frame is strong and the tires are full of high pressure. This non-damped design is to maximize the driving force of the rider through the transmission. The softer damping setting will disperse the more pedaling force, and the resulting bobbing will be proportional to the coefficient of damping softness. Between the comfort and performance is difficult to quantify The best adjustment of Controllability is the goal that bicycle manufacturers and enthusiasts have been pursuing.

Please refer to Taiwan Patent Application No. 106118742, which discloses a shock absorber that can be automatically adjusted. The main technical means is to use a three-axis acceleration sensor as a judgment of the road condition of the bicycle, and at the same time adjust the damping of the bicycle shock absorber so that The bicycle saves the rider's power on a smooth road, maintains a certain grip on the upside-down road, and provides the comfort of a rider on a bicycle.

It can be seen from the above description that although a technique for adjusting the shock absorber is disclosed, the following disadvantages are still encountered in actual testing:

First, too much noise:

It is easy to generate noise by detecting the road condition of the bicycle with a three-axis acceleration sensor. For example, when riding a bicycle, the vibration of the knight body itself generates a vibration signal, and the three-axis acceleration sensor cannot distinguish the vibration. The signal is from the vibration of the road or the vibration generated by the Cavaliers itself, which generates too much noise, and it is impossible to confirm which signals must be eliminated when making the circuit.

Second, it will be affected by the suspension effect:

It is conventional to place the three-axis acceleration sensor under the seat, and the detected vibration has been weakened by the shock absorber. The controller adjusts the damping of the shock absorber after receiving the detection information, and affects the three axes. The detection information of the acceleration sensor, under the control of the damping control circuit, causes the rider to feel that the bicycle is floating when riding.

Third, can not detect other conditions:

The triaxial acceleration sensor detects the change of the three axes of the three-dimensional space, but it cannot be judged for the conditions of vacating, uphill, downhill, braking, and starting.

Therefore, how to make the detected signal more correct, to correctly reflect the damping adjustment of the shock absorber, and to judge the riding condition of more kinds of bicycles is an urgent need for the technical staff.

Another technical means of the present invention is that in the device setting step, a three-axis acceleration sensor is further disposed on the bicycle, and the three-axis acceleration sensor is electrically connected to the damping controller, and the road condition classification step is performed. The classification module obtains the detection data of the three-axis acceleration sensor, and classifies the road condition according to the damping adjustment learning data to adjust the road condition classification data.

In actual implementation, the bicycle can be used without the seat. The suspension of the chair, the vibration of the bicycle is controlled by the front suspension and the rear suspension, that is, the damping of the front suspension and the rear suspension is not limited thereto.

The structure of the front shock absorber, the rear shock absorber, and the seat shock absorber is clearly disclosed in Taiwan Patent Application No. 106118742, which is not described in detail herein.

When the front wheel detector and the rear wheel detector use the tire pressure detector, the front wheel detector and the rear wheel detector are respectively disposed at the air nozzles of the front wheel frame and the rear wheel frame. In order to detect the difference between the external pressure and the tire pressure, the tire pressure of the front tire and the rear tire is further obtained. The front wheel detector and the rear wheel detector respectively have a wireless information transmission component, and the damping controller also has a wireless information transmission component for detecting tire pressure detection data of the front tire and the rear tire.

In actual implementation, the bicycle automatic damping adjustment device may not need to set the three-axis acceleration sensor, and should not be limited thereto.

The classification module provides the control module to analyze the driving condition of the bicycle, and the control module obtains the detection data of the front wheel detector and the rear wheel detector to control the front shock absorber and the rear shock absorber The classification module analyzes the detection information of the front wheel detector and the rear wheel detector to adjust the data stored in the classification module.

The rear shock absorber and the damping of the seat shock absorber. Preferably, the control module is advanced using an Advanced RISC Machine (ARM). The microcontroller, as the central controller of the suspension system, implements all the firmware in the Real-Time Operating System (RTOS) mode. In actual implementation, the control module can use other micro-controls. Devices or computer devices, such as embedded systems, should not be limited to this.

The classification module is a memory chip, which can store identification information of various road conditions, and each identification information is a data set of a band waveform change, so that the control module analyzes the detection of the front wheel detector and the rear wheel detector. data.

The judging module is a kind of self-organizing feature maps (SOM) network, which can input multi-objective parameters by using a Hiring-Organizing Map (GHSOM). And learning the different target road conditions to obtain the correct road condition information and store the correct road condition identification information in the classification module. In practice, other learning circuits can be used and should not be limited to this.

The damper controller further includes a noise canceller for canceling detection information of the front wheel detector and the rear wheel detector to eliminate high frequency or low frequency noise. Preferably, the noise canceller uses a discrete wavelet transform circuit. In actual implementation, other noise cancellers may also be used, and should not be limited thereto.

The use of the judgment module to analyze the change of the waveform to obtain the correct reaction data, and then provide the technical means for the control module to correctly analyze the data has been known to the industry and widely used in commercially available products. I will repeat the details.

Referring to FIG. 3, the bicycle automatic damping adjustment method of the preferred embodiment includes a device setting step 901, an initial setting step 902, a road condition classification step 903, a damping control step 904, and a repeating step 905.

Firstly, the device setting step is performed, and the front wheel detector is disposed on the front wheel moving structure of the bicycle, and the rear wheel detector is disposed on the rear wheel moving structure of the bicycle, the front wheel detector, and the rear wheel detector are The damping controller is electrically connected. The damping controller includes the control module, the determining module, and the classification module. The classification module stores a road condition classification data.

And then performing the initial setting step, inputting a damping adjustment learning data to the determining module, wherein the damping adjustment learning material is selected from a road condition learning parameter, an uphill learning parameter, a downhill learning parameter, a step learning parameter, and a brake. Learning parameters, a vacant learning parameter, one of them and a combination thereof.

When the inventor designs the circuit, the characteristics of different road conditions, plus the reaction of different tire pressures, plus the weight of different knights, input different learning parameters in the judgment module, so that the judgment module has learning. The goal is to further enable the classification module to provide the control module to correctly determine the road condition, and prevent the determination module from blindly modifying the data in the classification module.

The road condition learning parameter provides the judgment module to confirm the road condition of the bicycle, and the road condition includes a smooth road condition to a reverse road condition. For example, the amplitude of the detection data of the smooth road condition is smaller than the frequency. The detection data of the high and the reverse road has a relatively large amplitude and the information detected by the front wheel detector is substantially the same as that detected by the rear wheel detector.

The uphill learning parameter provides the determination module to confirm that the bicycle is traveling uphill. For example, the rear wheel detector has relatively heavy pressure detection data compared to the front wheel detector.

The downhill learning parameter provides the determining module to confirm that the bicycle is traveling downhill. For example, the front wheel detector has relatively heavy pressure detection data compared to the rear wheel detector.

The starting learning parameter provides the determining module to confirm that the bicycle is in a starting state. For example, the waveform of the data detected by the front wheel detector and the rear wheel detector is lower, because the knight is on the ground, not only The detection pressure is low, and the frequency is controlled by the knight's feet. The waveform of the detected data is not only longer, but also has a different frequency, which is completely different from the waveform when riding.

The brake learning parameter provides the determination module to confirm that the bicycle is in the brake state. For example, the detection pressure of the front wheel detector is increased when the brake is normal, and the detection pressure of the rear wheel detector is reduced, and the emergency is When the brake is applied, the detection pressure of the front wheel detector will increase instantaneously, and the detection pressure of the rear wheel detector will be instantaneously reduced.

The vacated learning parameter provides the determining module to confirm that the bicycle is in a vacated state. For example, when the bicycle is vacated, the front wheel detector and the rear wheel detector do not feel pressure.

It is worth mentioning that the road condition learning parameter, the uphill learning parameter, the downhill learning parameter, the starting learning parameter, the brake learning The parameters, and the vacancy learning can support each other. For example, when the uphill road section encounters a bumpy road condition, or when the road condition occurs in a bumpy road condition, the judgment module can learn. In addition, the determination module can further add the detection data of the three-axis acceleration sensor to assist in the determination of the road condition and the detection of the body tilt.

And then performing the road classification step. When a person (not shown) rides the bicycle, the determining module obtains the front wheel detector and the detection information of the rear wheel detector, and adjusts according to the damping. The learning data is used to classify the road conditions, and the road condition classification data is adjusted to enable the control module to judge the road condition by using the road condition classification data.

The determining module obtains the weight of the person according to the value of the front wheel detector and the rear wheel detector, and adjusts the road condition classification data according to the weight of the person.

And then performing the damping control step. When the person rides the bicycle, the control module obtains the detection information of the front wheel detector and the rear wheel detector, and controls the front wheel of the bicycle by using the road condition classification data. The moving structure and the damping of the rear wheel moving structure.

When the bicycle is running on a smooth road condition, the control module increases the damping of the front wheel moving structure and the rear wheel moving structure of the bicycle, that is, the damping of the front shock absorber and the rear shock absorber is increased. In order to make the suspension of the bicycle hard, the force of the person pedaling fully pushes the bicycle, and the person is not affected by the vibration of the road surface.

When the bicycle is driving in a bumpy road condition, the control module lowers the front wheel moving structure of the bicycle and the damping of the rear wheel moving structure. In order to soften the suspension of the bicycle and effectively offset the large amount of vibration caused by the bumpy road surface, the wrist and the spine of the person can be effectively protected.

When the bicycle is traveling uphill, the control module increases the damping of the rear wheel moving structure of the bicycle, and can also increase the damping of the front wheel moving structure, so that the pedaling force of the person is effectively transmitted to the climbing slope. When a large bounce is encountered, the suspension can be softened immediately. In actual implementation, the control module recognizes the angle of the uphill and appropriately adjusts the damping of the rear wheel moving structure.

When the bicycle is running downhill, the control module increases the damping of the front wheel moving structure of the bicycle, and can also increase the damping of the rear wheel moving structure, so that the rigidity of the bicycle body is hardened, and the suspension is avoided. When the crane is over-soft, and the rollover accident occurs, in actual implementation, the control module will recognize the angle of the downhill and appropriately adjust the damping of the moving structure of the front wheel.

When the bicycle is in a starting state, the control module increases the damping of the front wheel moving structure and the rear wheel moving structure of the bicycle. Preferably, the control module is a fully locked front shock absorber and the rear The flow of fluid in the shock absorber to completely transfer the pedaling force of the person to the start of the bicycle.

When the bicycle is in the braking state, the control module appropriately adjusts the damping of the bicycle front wheel moving structure, especially when the bicycle is in emergency braking, the control module must quickly change the front shock absorber The fluid is completely locked. For example, when the bicycle is braked urgently and the damper is actuated, the steering lever (faucet) of the bicycle will sink, there is a great chance of causing the condition of the rollover, or the stroke of the damper sinking Low, will produce a strong rebound force, the person's hand injury.

When the bicycle is in a vacated state, the control module lowers the front wheel moving structure of the bicycle and the damping of the rear wheel moving structure, that is, the front shock absorber, the rear shock absorber, and the seat The damping of the shock absorber is adjusted to the softest to cushion the reaction force generated by the ground when falling and protect the person from injury.

Referring to FIG. 4, the left side to the right side are the starting state, the upside state, the climbing state, the vacating state, and the braking state of the bicycle 31, respectively. When the bicycle 31 is in a starting state, the damping controller will increase the damping of the front and rear shock absorbers. When the bicycle 31 is in a reverse state, the damping controller will lower the damping of the front and rear shock absorbers. When the bicycle 31 is in a climbing state, the damping controller will increase the damping of the front and rear shock absorbers. When the bicycle 31 is in a vacated state, the damping controller will lower the damping of the front and rear shock absorbers. When the bicycle 31 is in a braking state, the damping controller will increase the damping of the front and rear shock absorbers.

Finally, the repeating step is performed, and the road condition classification step and the damping control step are repeatedly performed. Because the bicycle rider will change the weight of the bicycle to load, the chain will adhere to the dust and cause dirt and wear the force of the person to step on. The shock absorber will also change the damping due to dust adhesion or fluid outflow. The pressure will decrease with time, the tire pressure will become higher when the tire is inflated, and the detection data of the front wheel detector and the rear wheel detector are different. Therefore, the judging module detects the condition of the bicycle at any time, and adjusts the road condition classification data stored in the classification module to make the control mode Different sets of conditions, different personnel, different tire pressures, provide the most appropriate damping, so that the bicycle can maintain the most appropriate suspension at any time, so that the person riding the bicycle can ride comfortably.

It can be seen from the above description that the bicycle automatic damping adjustment method and device of the present invention have the following effects:

First, the road condition can be completely detected:

The front wheel detector and the rear wheel detector are mainly used as detectors for judging the types of road conditions, uphill, downhill, starting, braking, and vacating, and appropriately adjusting the damping. .

Second, accurately detect road conditions:

When the front wheel detector and the rear wheel detector use the tire pressure detector, the front wheel detector and the rear wheel detector are respectively disposed on the front wheel frame and the rear wheel frame, when the front wheel detection When the strain gauge is used by the rear wheel detector and the rear wheel detector, the front wheel detector is disposed on the front fork structure near the axis of the front wheel frame, and the rear wheel detector is disposed near the axis of the rear wheel frame After the fork structure, the influence of the front suspension and the rear suspension is avoided, and the road condition is accurately detected.

Third, you can immediately learn to adjust immediately:

The control module can learn according to different vehicle conditions, different personnel and different tire pressures to adjust the road condition classification data stored in the classification module, so that the control module adjusts the appropriate damping so that the bicycle can be used at any time. The most appropriate suspension is kept so that people riding the bicycle can ride comfortably.

In summary, the present invention uses self-organization The mapping module of the mapping image network (Growing Hierarchical. Self-Organizing Map, GHSOM), but the inventor of the present case tried to figure out the various road conditions encountered during the actual riding of the bicycle (including smooth road conditions, upside down Road conditions, uphill road conditions, downhill road conditions, starting road conditions, braking road conditions, and vacant road conditions) improve the learning parameters in the judgment module, so that the damping controller has added a variety of road conditions that can be correctly judged. The purpose of the present invention can be achieved by effectively improving the types of road conditions that the prior art cannot judge.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
