In general, there are automobiles, bicycles, airplanes, ships, trains, etc. are used by people.

Among these, bicycles are the most easily accessible means for people.

It also saves time and minimizes physical consumption when traveling short distances, and is much more convenient than walking, and it is convenient to carry a certain amount of things.

In particular, in recent times of high oil prices, more and more people use fast bicycles rather than walking to reduce fuel costs.

Electric bicycles are invented to make these convenient bicycles move more conveniently with less power.

Electric bicycles can climb uphill slopes, which are difficult to climb by ordinary bicycles, using motor power more easily, and can run faster than ordinary bicycles on flat lands.

However, the existing bicycles and electric bicycles do not provide driving information unlike cars. That is, existing bicycles and electric bicycles can not easily check the driving information (speed, output, driving distance, etc.) and the vehicle status of the vehicle can be seen in the vehicle.

Therefore, in the case of the conventional general bicycle, there is a disadvantage in that it is not provided with appropriate driving information suitable for road conditions due to the lack of driving information.

In addition, in the case of the existing electric bicycle to adjust the amount of electric motor output by the hand of a person can enjoy a sense of speed by direct control of the person, but there is a disadvantage that acts as an inefficient factor when using the battery.

In other words, in the case of the existing electric bicycle, it is trying to climb the ramp using only the electric motor motor power by generating excessive output on the flat and uphill due to manual operation, and use it like a motorcycle to enjoy the speed without pedaling on the flat By doing so, there are many problems such as inefficient consumption in terms of power consumption.

In this case, the multi-sensor further comprises a sensor for detecting at least one of the calories burned by the driver due to the temperature, humidity, barometric pressure, direction, travel distance, driving.

In addition, an output servo motor is provided between the AVR control circuit and the BLDC motor to control the output value of the BLDC motor by changing a variable resistance value by changing the rotation angle according to the operation of the AVR control circuit.

In addition, a wire wheel is axially coupled to the shifting servo motor, and a gear shifting wire is installed to the wire wheel so as to be wound or unrolled according to the rotational direction of the wire wheel according to the driving of the shifting servo motor. It is done.

The information provided on the screen to the driver may include recommended driving information recommending a speed change and a shift in addition to the driving information related to the driving environment.

Etc.) provides the driver with the opportunity to drive selectively.In the case of electric bicycles, the motor power and gear shifts are automatically performed according to the conditions of flat, uphill and downhill roads. It is possible and is expected to enable more convenient driving.

That is, the present invention provides an effect that can improve the driving convenience and efficiency of the electric bicycle driver.

It is assumed to mean.

Referring to these drawings, the electric bicycle control apparatus of the present invention includes a multi-sensor for detecting various driving information including tilt and speed; An AVR control circuit for outputting a control signal for adjusting a motor output or performing a gear shift in accordance with the signal detected by the multiple sensors; A BLDC motor for outputting an output adjusted according to a control signal of the AVR control circuit; A shift servo motor for shifting gears in accordance with a control signal of the AVR control circuit; It is configured to include a display unit for providing a driver with various driving information detected by the multi-sensor.

In this case, the multi-sensor further includes a sensor capable of detecting at least one of the calories burned by the driver due to temperature, humidity, barometric pressure, direction, travel distance, driving.

In addition, an output servomotor is provided between the AVR control circuit and the BLDC motor to control the output value of the BLDC motor by changing a variable resistance value through a change in the rotation angle according to the operation of the AVR control circuit.

In addition, a wire wheel is axially coupled to the shifting servo motor, and a gear shifting wire is installed to the wire wheel so as to be wound or unrolled in accordance with the rotation direction of the wire wheel according to the driving of the shifting servo motor. .

The control process of the electric bicycle of the present invention configured as described above is as follows.

Hereinafter, with reference to these drawings, the output of the electric bicycle and the gear shift control process, and the posture information acquisition and driving information providing process for the electric bicycle for this process will be described for each process.

First, a process of providing driving information and recommended driving information using multiple sensors will be described.

When driving an electric bicycle, the driving information is sensed and calculated by using multiple sensors to display the screen for the driver to view and to provide recommended driving information. In addition, the driver selectively selects the manual mode or the automatic mode to control the output of the motor in the case of gear shift and electric bicycle.

Next, the gear shifting process will be described.

When the bicycle enters an uphill slope or when it enters a downhill slope, and when driving on a flat surface, the shift servomotor in charge of the gear shift is calculated by the AVR circuit according to the inclination signal value sensed by the tilt sensor. The signal is sent, and thus the gearing servo is rotated at a predetermined angle so that the gear is shifted.

That is, referring to Figure 2, when the transmission servo motor rotates at a predetermined angle, the wire wheel connected to the shaft is rotated and the wire connected to the gear transmission is wound or unrolled according to the rotation of the wire wheel gear shifting Will be done.

Next, the output control process of the electric bicycle will be described.

An output servo that adjusts the output of the BLDC motor through the calculation of the inclination signal sensed by the tilt sensor by dividing when the bicycle enters an uphill slope or a downhill slope, and when driving on a flat surface. Send a signal to the motor to rotate by a certain angle.

That is, as can be seen from the signal transmission form shown in Figure 3, it was decided to use a variable resistor as a method of adjusting the output of the BLDC motor, and directly connected to the output servo motor, according to the signal value according to the slope for the output The servomotor was rotated to adjust the resistance to adjust the final output of the BLDC motor.

On the other hand, the electric bicycle is not only to be able to run the pedal by the force of the human when running, there is also a hybrid electric bike that can be run by the motor power, the following describes the driving control process of the hybrid electric bike.

First, the control process in flat driving defined by a slope larger than -3 ° and smaller than 3 ° will be described.

While driving on a flat surface (an inclination greater than -3 ° and less than 3 °), the pedal can be driven by human force, but in general, people run at the maximum motor output to run with only the motor power without using their own power more conveniently. . If you run like this, the battery becomes faster, and it may be difficult to run the ramp by exhausting the battery when driving uphill.

Therefore, on a flat surface, the gear is shifted to a high speed gear while maintaining the motor output at about the middle of the maximum output, so that a human electric vehicle can be added to drive the hybrid electric bicycle.

That is, when the hybrid electric bicycle runs on a flat surface, the tilt sensor sends a signal to the AVR control circuit according to the inclination of the slope, and an output servo that is in charge of motor power control after calculation through a program inputted using this signal. Each signal is sent to the transmission servomotor in charge of the motor and gear shift control, and the gear is shifted at high speed, and the output of the BLDC motor is maintained at an intermediate level. Accordingly, if the user wants to travel at the desired speed, he or she must roll the pedal to add more force.

Next, a description will be given of a control process for traveling uphill at 3 ° or more.

When climbing uphill slopes, try to maximize the output of the motor, just like a normal electric bike. This is to minimize the fatigue of people when climbing uphill slopes and to climb using the minimum force. And the gear of the bike is also changed to the low gear to make climbing easier.

First, when the bicycle enters an uphill slope, the tilt sensor sends a signal to the AVR circuit according to the slope of the slope, and the servo motor and gear shift that are in charge of motor power control after calculation through the program inputted using this signal are used. Each signal is sent to the servo motor in charge to shift the gear at low speed and maximize the output of the motor.

Finally, the control process for driving downhill slopes of -3 ° or less will be described.

When you go downhill, the acceleration is applied by gravity when you go down, so the speed increases. Therefore, the output of the motor is not necessary, but rather the speed is reduced by using the brake. In case of the downhill slope which cuts off the motor output and the gear also appears after flat driving, it can be safely lowered by changing to the low gear.

First, when the bicycle enters the downhill slope, the tilt sensor sends a signal to the AVR control circuit according to the inclination of the slope, and the output servo motor which is in charge of motor power control after calculation through the input program using this signal Each signal is sent to the transmission servomotor in charge of gear shift control to shift the gear at low speed, and the downhill slope is lowered while the output of the BLDC motor is cut off.
