Description of the invention: [Technical field to which the invention pertains] In particular, there is a method of assisting compensation for an electric assist bicycle of the present invention and an electric assist bicycle. r [Prior Art] The electric power-assisted bicycle is different from the electric scooter. The electric power is not intended to replace the rider's power. The purpose is to supplement the power in a timely and stable county environment, for example: Look for exercise _ to assist compensation, in order to increase the rider in the Bi::it sense 'and also retain the rider to ride with his own strength (four) Γ electric power bicycle operating principle through the majority of sensing for the riding period Related information, 15 20 provided, 1 to achieve the purpose of power compensation, 'correction motor 4 read the ninth map' f know the power assist bicycle compensation method = compensation: the user has the pedal force to generate 'the motor according to a constant K Provide power generation] p assist = user's pedaling force x constant κ; when the user does not step on the user's wealth to provide assistance; among them, the setting of the solid-value = κ varies according to individual needs' is not determined; Furthermore, since the load will change with the road surface condition, '=.= needs to be touched; if the material U is not properly set, the constant κ is set too low, and the power compensation cannot be effectively provided. 1. Although the constant Κ setting is too high, the material gj assists excessive compensation and the 4 201002571 makes the sense of resistance felt by the human body too low; in other words, the rider loses the feeling of riding the bicycle by himself = quantity, thereby reducing The fun of riding; In addition, although the compensation is too much, it will cause unnecessary power consumption and has the disadvantage of energy consumption. 5 Therefore, in the case that the user does not know the load size, the user reports difficulty in directly adjusting the constant κ to obtain appropriate power compensation; if considering factors such as road surface change and personal demand, the constant κ has to be adjusted. In other words, the conventional electric assist bicycle has the disadvantages of being inconvenient to use. 1〇, In summary, the assist compensation method for the electric assist bicycle has the above-mentioned deficiency and needs to be improved. The main purpose of the present invention is to provide an electric assist bicycle, which is characterized in that it is easy to use and has the advantage of being convenient to use. The help = compensation method, which can provide appropriate power immediately and effectively, and reduce the waste of electric energy, has the advantages of better compensation effect and energy saving. 20 To achieve the above object, the present invention provides a power assist compensation for an electric assist bicycle. The method comprises the steps of: a) utilizing a torsion sensor Detecting the torque output of the pedal of the electric assist bicycle; using a motor speed sensor to detect the rotation speed of the motor of the electric assist bicycle, and using a wheel speed sensor to detect the electric assist bicycle The speed of the wheel 5 201002571; b) using the processor to calculate according to the above information: supplement ^ (4) (four) 贞 __ 'material defeat: up to 5 5 by this 'the assistive step of the electric assist bicycle of the invention' can actively push the Load value _ (4) The size of the force compensation; compared with the === suitable power = color. In addition, 'this hair · enough (four) and effectively boost the power 'while reducing the waste of electrical energy, · compared to the practitioner, Dan: The effect of assisting compensation is better and the characteristics of energy saving. 1 [Embodiment] Soil and in order to elaborate on the advantages and functions of the Japanese invention, the following preferred embodiments are described with reference to the following: The flow chart of the steps of a preferred embodiment of the present invention.

A) use - torque sensor (10), with To detect a power-assisted white (not shown), the pedaling mountain ΑΑ α 罨 罨 助 助 助 ( ( 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以 用以====: 助助力自料=轮^τι速感湘(10), use (4) to measure the electricity The controller (4〇) is based on the above information to estimate the speed sensing _, the motor speed sensing _, and ί (10) is the continuous system 'to make the load value _ should ride the rider 2 multiplication status and the road surface condition change The continuous update is provided; the load value provided in this embodiment is merely an example, and is not a limitation. C) The processor (4〇) uses the load value as a reference value, and then actively controls the power assist compensation; in this embodiment, the processor _, drives the motor (1) via the drive module (5〇) This is for illustrative purposes only and is not intended to be limiting; the processor (40) has a first mode _ and a second mode for the 'seater selection; the processor (4 〇) is in the first mode (10) The selected one of the second modes (62) performs power assist compensation: wherein the second mode (60) and the second mode (62) are as follows: Please refer to the fourth and fifth figures, when riding The occupant selects the first mode (60) 'The processing procedure of the processor (40) is as follows: 20 201002571 5 10 15 • i'. Then, the motor (1) loads the motor (1) and does not output boost. The treading force is less than this. The §t constant (four) responds to the _ person's == lose = by r help? Compensation == The sense of resistance that the human body can feel forms the feeling of riding the bicycle 2's compared to the second Enough = The case gives two fun to ride. This is only referred to ♦ sixth figure and seventh figure 'When the rider selects the mode of the brother (62), the processing procedure of the processor (40) is as follows: c3) using the torque sensor (1〇) - Torque value; c4) The increase in the pedaling force of the rider is regarded as an increase in the torque value. Although the torque value is greater than zero, the motor (丨) output assist increases as the torque value increases; in this embodiment, the motor (1) The output assist is linear with the torque value, which is merely an example and is not a limitation; when the torque value is equal to zero, the motor (1) does not output boost. Thereby, the embodiment can directly use the torque value to reflect the use state of the rider, which is more instant than the first mode (60) using the load value inferer' the second mode (62) Compensation is made in response to the rider's use status; as shown in the seventh figure, the second mode 8 20 201002571 (62) is sufficient to provide greater assistance at the start to facilitate the electric assist/brake parking. έ之, § 苐 苐 模式 模式 62 62 62 = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Furthermore, the 5th second mode (62) is less prone to generate more power than the first mode (6〇), so that the sense of resistance that the human body can feel is more resistant to actual resistance; in other words, riding The rider can also have the feeling of riding a bicycle with his own amount and retaining the ride. The first mode (6G) of the embodiment of the present invention can improve the problem of helping the excessive _, thereby reducing the wave of electric energy; the acquaintance of the present invention has the characteristics of better compensation effect and energy saving. Then: ° 15 3 =, equation (62) 'Because the electric assisted bicycle is in the heart, 7* has acceleration, the electric assist bicycle has a drop in the assist h, and the second mode (62) can respond to this situation. And ^ sample has the characteristics of better compensation and energy saving. ? In the same way, this implementation touches the above steps, and adjusts the output state of the motor (1) according to the load value, and the size of the compensation is obtained; compared with the conventional user, the mobilizer assists the present Appropriate and effective to provide appropriate assistance, n = special color, compared to the user's help to supplement d 9 20 201002571 [schematic description] The first figure is a step flow of a preferred embodiment of the present invention Figure.
