Description
Technical Field
The invention relates to the technical field of electric power assistance, in particular to an electric power-assisted bicycle system.
Background
The PAS (Power Assist System), i.e., an "electric Power assisted bicycle System", is called "Pedelec" in europe, i.e., a bicycle with a "Power Assist System" having pedals. PAS (Power Assist System) generally includes five parts, a motor, a controller, a sensor, a battery, and a human-machine interface (meter). In the true sense, an electrically assisted bicycle (Pedelec) is allowed to operate only in an assisted mode, i.e. it must be a "human + electric" hybrid output mode, and not in a purely electric mode. Because the safety and the reliability of riding have been guaranteed effectively to the helping hand drive mode, when complying with the traffic safety regulation, both increased the continuation of the journey mileage of once charging by a wide margin, also effectively avoided the increase of whole car weight, still played the dual effect of riding instead of walk and body-building, let people can ride light when keeping riding experience to it is farther to ride. "the electronic helping hand of bicycle" has been popularized in europe and japan, and electronic helping hand bicycle can let ride and become more relaxed on the basis that does not change traditional mode of riding, has solved the hard problem of riding the bicycle, has remain the enjoyment of riding the bicycle again, lets ordinary people can easily ride farther, lets the not good people of physical stamina equally can experience the happy of riding.
The most typical electric boosting technology of the current bicycle is that the force of a rider in the pedaling riding process is detected and collected based on a torque sensor, the output power of a driving motor of the electric bicycle is intelligently adjusted through a single chip microcomputer according to different road conditions (such as difference between flat road riding and climbing road) and subjective intention of the rider expecting speed, so that the output power of the driving motor of the electric bicycle is in a certain proportion to the pedaling power output by the rider, and accordingly perfect riding experience is provided. The following describes an electric power-assisted bicycle system based on a "torque sensor".
In the field of electric power-assisted bicycles (pedelc), "Torque sensors" (Torque sensors) are the most important technology, and since research and development thresholds are high, a few international companies such as BOSCH in germany and YAMAHA in japan form a significant technical barrier, which is a main reason why electric power-assisted bicycles using "Torque sensors" are expensive to sell.
The principle of the 'torque sensor' technology is as follows: the micro deformation of the metal surface invisible to human eyes is detected, so that the measuring precision of the torque sensor is very high, and the torque sensor is also very sensitive and can measure very small stress. Because the torque sensor is sensitive and high in precision, the electric power-assisted bicycle using the torque sensor can output power assistance almost instantly while pedaling, and other types can have obvious power assistance hysteresis. The measurement of the torque sensor is carried out at all times, so the torque sensor is very linear, and the output boosting force can always meet the riding requirement just.
A controller of an electric power-assisted bicycle based on a 'torque sensor' is a core electric control device of a vehicle, a controller hardware platform driven by a direct-current brushless motor is built based on a master control single chip microcomputer in the controller, system control software adopting an assembly and C language mixed programming mode is adopted, the 'torque sensor' collects the pedaling force of a rider in real time in the riding process, collected data signals are transmitted to the controller, then the controller runs the processing of high-frequency digital signals and analog signals, and the corresponding electric control software algorithm is matched to realize the current regulation and control of the direct-current brushless motor, so that the output power, the rotating speed and the torque of the motor are controlled.
With japan and europe and the united states of america advocating bicycles as personal vehicles, "torque sensors" are eventually applied to electric power-assisted bicycles. The bilateral torque sensor can measure the forces of two pedals, is mainly arranged between the crank and the chain wheel, namely the outer side of the five-way joint, and is directly arranged on the middle shaft in some cases. There is no absolute rigid body in the world, so the middle shaft will generate very fine torsion deformation when stressed, the magnitude of the current stepping moment can be obtained by measuring the fine deformation signal on the surface of the middle shaft, the precision requirement of the moment sensor is high theoretically, because the moment is measured by the torsion, the moment sensor is also called as a 'torque sensor'.
The realization principle of prior art is based on through "torque sensor" device, and the power that the person's of riding was ridden to the bipedal of in-process is pedaled in real time measurement and collection, adopts power signal data as electric power assisted bicycle controller's raw data, realizes the electronic helping hand of bicycle, can not laminate human physiology and motion function state, leads to riding the person and rides the comfort level and ride and experience lowly, also has certain potential safety hazard.

The essence of the 'deep integration' is the core of the concept and the idea of the invention, and the greatest function of the product is 'detection' when looking at various hardware devices such as intelligent bracelets, medical detection sensor instruments and the like in the market. In popular terms, most of human body function signal detection products on the market at present have data of 'being used for seeing'; the idea of the invention is to use the detected human body function data.

In one embodiment, the vital signs monitoring device may comprise: the heart rate monitoring device is used for monitoring the heart rate of a rider during riding;
controlling means specifically can be used for when riding after the rhythm of the heart when the passerby rides exceeds the safe rhythm of the heart of riding of the passerby, according to the relation that the rhythm of the heart when riding the passerby surpasss the range of the safe rhythm of the heart of riding of the passerby and the output power scope of motor, output power regulation as the matching of the passerby of riding physiological state when riding the passerby.
In particular embodiments, the heart rate monitoring device may be a heart rate monitor. Whether the heart rate of the rider is within a normal value range or not is judged, for example, whether the exercise amount is appropriate or not is judged, and vital sign monitoring devices such as a heart rate meter can give out prompts. The specific setting method of the range of the safe riding heart rate can comprise the following steps: the method for determining the lower limit of the range of the safe riding heart rate can be as follows: the amount of exercise can be measured by heart rate, such as: when aerobic exercise is effective and safe, the heart rate of a person is 170 minus the age number, or 108-144. The determination method of the upper limit of the range of the safe riding heart rate can be as follows: according to the sports medicine study, there is a very direct link between heart rate and fat consumption for aerobic exercise, a simple formula calculates your maximum heart rate: 220 minus age.

In specific implementation, the relationship between the range of the heart rate exceeding the safe riding heart rate of the rider during riding and the output power range of the motor can be a functional relation, and can also be a chart shown in the following table 1, wherein the following table 1 is a heart rate and motor output power comparison table:

| Is 50 percent higher than the normal exercise heart rate of the rider individual | 250W |
TABLE 1
In one embodiment, the vital signs monitoring device may comprise: the respiratory frequency monitoring device is used for monitoring the respiratory frequency of a rider during riding in real time;
the control device can also be used for adjusting the output power of the motor of the electric power-assisted bicycle to match the output power of the physiological state when the rider rides according to the relation between the range of the respiratory frequency of the rider exceeding the safe riding respiratory frequency of the rider and the output power range of the motor when the respiratory frequency of the rider rides exceeds the safe riding respiratory frequency of the rider.
In specific implementation, the method for determining the range of the safe riding breathing frequency of the rider can comprise the following steps: respiratory rate normal value: the two sides of the normal respiratory motion are basically symmetrical, the rhythm is uniform, the depth is moderate, and the frequency and the rhythm of the respiratory motion of a normal person are as follows: the ratio of the respiratory rate of 12 to 20 times/minute to the pulse is about 1: 4, the rhythm is uniform and regular. Adults breathe more than 24 times per minute and are called tachypnea. Adults breathe less than 10 times per minute and are called hypopneas.
When the intelligent bracelet is in a state that the breathing frequency of a rider in the riding motion process exceeds a normal value to form the state of overspeed breathing commonly called 'panting', the intelligent bracelet transmits the data to the control device, the control device provides corresponding output power for the motor, the output power of the motor is controlled to be adjusted to be matched with the output power of the real-time physiological state of the rider in real time, the amount of human body exercise is reduced, and the breathing frequency is adjusted to return to normal.
The embodiment of the invention takes the blood pressure value and the blood oxygen value of the rider as the synchronous human body function state monitoring data and can be used as an auxiliary reference application data source.
In one embodiment, the vital signs monitoring device may comprise: the blood pressure monitoring device is used for monitoring the blood pressure of a rider during riding in real time;
the control device can also be used for adjusting the output power of the motor of the electric power-assisted bicycle to match the output power of the physiological state of the rider during riding according to the relation between the range of the blood pressure of the rider during riding and the safe riding blood pressure of the rider and the output power range of the motor after the blood pressure of the rider during riding exceeds the safe riding blood pressure of the rider.
In particular implementation, the method for determining the range of the safe riding blood pressure of the rider can comprise the following steps: blood pressure normal value: when a normal person is in a quiet state, the systolic pressure is 90-140 mmHg, the diastolic pressure is 60-90 mmHg, and the pulse pressure is 30-40 mmHg. Hypertension is called when the systolic pressure reaches 160mmHg or above and the diastolic pressure is more than or equal to 95 mmHg; critical hypertension is called when the systolic pressure is 141-159 mmHg or the diastolic pressure is 91-94 mmHg; systolic pressure is lower than 90mmHg and diastolic pressure is lower than 60mmHg, called hypotension.
In one embodiment, as shown in fig. 2, the electric bicycle system may further include: the pressure-sensitive weighing sensor is arranged below the bicycle seat, is connected with the control device and is used for detecting the weight data of a rider;
the control device may be further configured to adjust the start output power of the electric power-assisted bicycle motor to a start output power matching the rider's weight based on the detected rider's weight data.
In one embodiment, the control device may be specifically configured to adjust the start output power of the motor of the electrically assisted bicycle to match the start output power of the weight of the rider based on the detected weight data of the rider and a relationship between the weight data and the start output power of the motor.
The invention aims to provide a pressure-sensitive weighing sensor in the embodiment of the invention, and mainly aims to perform sensing control on the output power of a motor in a riding starting stage. The weights of the riders are different, and different fat and lean weights are related to the strength consumption degree of the riders when starting. Popular examples show that riders with heavy weights are relatively hard to ride and start, the force consumption in the starting stage is large, and the riding comfort level is poor; the rider with light weight has relatively small riding starting load and relatively labor-saving starting. The electric power bicycle is combined with an electric power bicycle system, namely, the pressure-sensitive weighing sensor is adopted, after a rider sits on a seat cushion of the bicycle, the weight value of the rider is measured by the pressure-sensitive weighing sensor, the data is led into a software algorithm of a controller, and the algorithm of control software correspondingly controls the output power of a motor according to the weight value of the rider collected by the sensor, so that the comfortable riding experience effect of 'body custom' more conforming to the actual riding weight under different weight differences of 'fat rider' and 'thin rider' is realized.
For example: a rider A: weight 45 kg → a pressure-sensitive weighing sensor collects weight data → transmits the weight data to a controller for operation → controls a motor to output (start) 70W power;
b, the rider: 65 kg of body weight → a pressure-sensitive weighing sensor collects body weight data → transmits the body weight data to a controller for operation → controls a motor to output (start) 100W power;
rider C: the weight is 100 kg → the pressure-sensitive weighing sensor collects weight data → the weight data is transmitted to the controller for operation → the motor is controlled to output (start) 250W power.
In specific implementation, the relationship between the weight data and the motor output starting power may be a functional relation, or may be a graph illustrated in the following table 2, where the following table 2 is the relationship between the weight data and the motor output starting power:
| body weight range | Range of motor output power |
| 45-55KG | 70W |
| 56-69KG | 100W |
| 70-85KG | 150W |
| 86-100KG | 250W |
TABLE 2
In one embodiment, as shown in fig. 2, the electric bicycle system may further include: the moment sensor is connected with the control device and used for monitoring pedaling force data of a rider during riding in real time;
the control device can also be used for adjusting the output power of the motor of the electric power-assisted bicycle to be matched with the output power of the physiological state of a rider during riding according to the pedaling force data and the vital sign data.
Under general conditions, the intelligent bracelet monitors the multi-element data and the pressure weighing sensor data, and is applied to the use under the condition of no torque sensor. Meanwhile, the torque sensor can also be simultaneously used in the electric power-assisted bicycle system provided by the embodiment of the invention.
In principle, the moment sensor collects force data of two pedals of the bicycle treaded by two feet of a rider; and what intelligent bracelet (vital sign monitoring devices) monitored is human "four big vital signs" data, and it belongs to human function state data when moving, consequently:
① force data are control calculation variables of 'hard' and 'mechanical' and require relative accuracy and absolute;
② human body function state data, which belongs to the control calculation reference of 'flexibility' and 'intelligent man-machine interaction', and requires relative fuzziness and coverage;
under the condition that the torque sensor and the intelligent bracelet monitor multiple human body function data are used simultaneously, the invention sets and coordinates the work cooperation mechanism of the two sensors through a specific control software algorithm. The following describes a mode for adjusting the output power of the motor of the electric power-assisted bicycle in real time according to the pedaling force data and the vital sign data.
In one embodiment, the control device may be specifically configured to use the pedaling force data as the dominant control command data, use the vital sign data as the reference data, and adjust the output power of the motor of the electric power-assisted bicycle, and when one of the vital sign data is out of the set normal value range, adjust the output power of the motor of the electric power-assisted bicycle to match the output power of the physiological state of the rider during riding according to the vital sign data.
In the specific implementation process, the control device controls the power output of a motor in a riding starting stage under the condition that the torque and the intelligent bracelet human-computer interaction sensor are simultaneously applied, and data of the pressure sensor is used as control command data; in the riding process, the pedaling force of the torque sensor is used as the leading control command data, the multi-element data collected by the intelligent bracelet in the process is used as the detection reference data of the control system on the human body state, and once one of the data in the human body function data exceeds the set normal value range, the system algorithm is correspondingly switched to the mode using the intelligent bracelet data as the control command data.
In one embodiment, the control device can be specifically configured to calculate the output power of the motor of the electric power-assisted bicycle matching the physiological state of the rider during riding according to the vital sign data, adjust the calculated output power of the motor of the electric power-assisted bicycle matching the physiological state of the rider during riding according to the pedaling force data, and adjust the output power of the motor of the electric power-assisted bicycle to match the output power of the motor of the electric power-assisted bicycle matching the physiological state of the rider during riding according to the adjusted output power of the motor of the electric power-assisted bicycle matching the physiological state of the rider during riding.
In specific implementation, the calculation is performed according to the data of the smart band, and the secondary adjustment is performed on the output power of the motor adjusted according to the data of the torque sensor, for example, when the human body function data is judged to be in a normal state, the output power of the motor calculated according to the data of the torque sensor is 70W, and when the human body function data is judged to be in a fatigue state, the output power of the motor calculated according to the same data of the torque sensor needs to be adjusted to be 100W.
In one embodiment, as shown in fig. 2, the vital signs monitoring device may be a sports bracelet.
Compared with the prior intelligent bracelet which only plays a role in collecting and monitoring human physiological data, the intelligent bracelet is characterized in that the collected human physiological data is input into the control device, the calculation of data elements for a software algorithm based on real-time human physiological data is realized, the collected human physiological data is fused and processed, and the ' inorganic ' data which is originally only used for ' display ' is changed into ' organic ' original data ' raw materials which can be used for electrical control. The system is obviously different from a man-machine interaction system which is used for controlling the power output of the motor in a mode of only playing the roles of acquisition and observation monitoring.
The instrument and the sensor which can be realized by the prior art are used for monitoring and reading various physiological state signals of a human body. The intelligent bracelet with the functions of monitoring the physiological state of a human body and acquiring biological signals is only used for monitoring and reading the physiological state of the human body at present, and the acquired physiological signal data of the human body is only used for watching in popular terms. For example, after wearing the smart band, the human physiological state monitoring function of the smart band starts to work, the heart rate, blood pressure, blood oxygen, respiratory rate, sleep time, fatigue degree and emotion … … of the human body are monitored in real time or periodically, and then the monitored and collected human physiological state data are displayed on the smart band or are interconnected with the mobile phone to transmit the data to the mobile phone, so that a user who wears the smart band can master and know the data.
According to the technical scheme, the human physiological signal data can be applied from the existing function only used as monitoring, the human physiological signal data is fused and expanded to be used as a calculation original parameter of the control algorithm of the electric power-assisted bicycle based on the human physiological signal data, the human physiological information data is converted into a valuable data raw material which can interact with equipment, and the equipment can read, understand and respond.
The technical scheme provided by the embodiment of the invention can achieve the following beneficial technical effects:
① real-time physiological signal data such as heart rate, blood oxygen, blood pressure, respiratory rate, body temperature, emotion, fatigue degree, etc. are collected as sensors based on an intelligent bracelet with real-time monitoring function for various human physiological signals such as heart rate, blood oxygen, blood pressure, respiratory rate, body temperature, emotion, fatigue degree, etc. and transmitted to a controller of an electric power bicycle, and the output power of a driving motor of the electric power bicycle is logically controlled and adjusted according to a corresponding algorithm through a software algorithm operated by a core control singlechip in the controller, so that the real-time motor and the pedaling power output by a rider are in a certain proportion, thereby providing comfortable riding experience combining the human physiological real-time state deeply.
