New Description: [New Technology Field] This creation provides an electric hub motor drive system that is related to the electric equipment or power unit of an electric vehicle. [Prior Art] With the increasing population of the world, the energy shortage problem that comes with it has gradually surfaced. From the perspective of the industry, almost all of the fuel engines have been used as the main driving force in the past. There is a combination of power or electric power driven by electric power. In the case of electric vehicles, the conventional electric vehicle driving method is shown in Figure 2-1, and the electric vehicle driving system 1 shown in Figure 1 The two microprocessors 12 are respectively connected by a host controller, and each of the microprocessors 12 is further connected to a driver 13^, and each driver 13 drives a hub motor 14 disposed on the wheel, respectively. 14 respectively controlling two front wheels or two rear wheels; and the electric vehicle drive system 20 as shown in FIG. 2 is connected to a single drive & by a single microprocessor 21, and the drive 22 drives four settings separately. The wheel hub motor is strong, so as to synchronously control the four wheels; t 曰 The electric vehicle drive system described above can be driven, but the drive is mainly driven by the upper controller U or the microprocessor 21 The main control drive, when the electric bicycle encounters a turn or the road condition changes, causing the load of each wheel to change, the upper control n and the microprocessor 21 cannot be controlled for driving conditions or road conditions. It is not only possible that the electric vehicle's traveling process M437007 is not smooth, but it is more likely to cause power loss. In view of this, the author has conceived and studied more deeply, and finally created an electric hub motor drive system. [New Content] This product provides a kind of electric recording object. Its main purpose is to solve the problem that the electric vehicle driving system cannot separately sense and separately adjust and adjust each wheel. In order to achieve the above objective, the present invention provides an electric hub motor drive system, which is controlled by a top (four) n electrical connection to control the four motor unit units, and each of the hub motor drive units is capable of separately controlling each wheel to control each wheel. In this way, when the single-wheel is in a driving situation or encounters different road conditions, it can immediately sense and control, so as to ensure the smoothness of driving. [Embodiment] In order to make the Beck Review Committee further understand and compile the purpose, characteristics and efficacy of this creation, the following riding cooperation [Figure Lai Lai Lai] is detailed as follows: The creation of the electric wheel valley motor drive system includes - The upper controller A is electrically connected to the four-wheel valley motor driving unit as shown in FIG. 3, and the respective valley motor driving units are as shown in FIG. 4, and include: a battery, and 30, a package of 3 multiple batteries in series The sub-battery of the battery pack 30 of the present embodiment is a DC clock iron battery; the voltage sensor 40' is electrically connected to the battery pack 3〇 and can sense the voltage change of the battery pack 30; the driver 50' electrical property Connecting the voltage sensor 4〇, the driver is connected to the battery pack 3〇 through the 4 M437007 voltage sensor 40, and the driver 5〇 can convert the DC power of the battery pack 30 into an AC output, and the driver 5〇 can change the power of the wheel; a driving controller 60 is electrically connected to the voltage sensor 4〇 and the driver 5〇, the driving controller 60 can sense the battery pack at the voltage sensor 4〇 3〇The battery is electro-voltage, When the divided battery voltages are not uniform, the drive controller 60 controls the equalization charging so that the voltages of the respective battery cells are equal, and the drive controller 6〇 can control the drive 5〇Φ to change the output power; and a hub motor 70 'Electrically connected to the drive controller 60 and the driver 50, the drive H 50 outputs alternating current to drive the hub motor 7 〇, the gang motor 7 〇 is disposed in the rim of the wheel (9), and the miscellaneous (four) reaches 7 Three Hall sensors 71 are respectively embedded in different positions, and each of the Hall sensors 71 is electrically connected to the driver 60. Each of the Hall sensors 71 can be operated when the wheel 8 is running. The position of the sensing wheel motor is transmitted to the driving controller by the signal of the position of the motor 7〇, and the driving controller 6〇 calculates the position signal of the wheel motor 4 (four) and converts it into the speed 'at the same time' The drive controller 6〇 can control the output of the driver 5〇 to the disassembly wheel according to the rotational speed of each wheel and can (4) the average speed of each wheel. The above is the structural relationship of the electric roller motor drive system of the present invention. When in use, the battery pack 30 outputs direct current, and the driver 5 converts the direct current outputted from the battery pack 3 into alternating current and drives each wheel to the motor 7〇. Drive the wheel 8 〇, · And when it is closed, when there is driving condition or road condition change, the speed of each wheel 80 may change separately, and each wheel is compared with the Hall sensor on the motor 7? ! 5 will sense the position of the hub motor 70' and the drive controller 60 converts the signal sensed by the Hall sensor 71 into a speed message and transmits the message to the driver 5, and the upper controller A can The speed of the wheel motor of each hub motor driving unit is sensed. When the speed of each wheel 80 is different, each driver 50 can be controlled by the drive controller 6 , and each driver 50 controls the output power and changes the output power. The rotation speed of each wheel 80 is the same as the smoothness of the lifting travel; and when the voltage of each battery of the battery pack 30 may be changed separately after using for a period of time, the sensing through the voltage sensor 4〇 may be Immediately know the situation, and the drive controller 6 电 electrically connected to the voltage sensor 40 can uniformly charge the battery pack 3, so that the power of each battery of the battery pack 30 is equal, and the electric vehicle is ensured. Further, when the electric vehicle is in a state in which the traveling speed is low, for example, when braking, the drive controller 60 senses the rotation speed and controls the driver 50 to return the output alternating current portion to the battery pack 30. The battery pack 30 can be charged using surplus electric power, improve the utilization of energy sources.
