For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0035] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] The present embodiment provides an electric control architecture for a multi-wheel drive electric vehicle, which can realize human pedaling and achieve power generation effect for the electric vehicle, and can be controlled through a control algorithm. The electric bicycle can generate electricity and recover energy during driving, and can achieve the purpose of extending the range. The present invention can also perform battery replacement and multi-battery management to achieve the purpose of long-term operation.

[0037] Combination Figures 1 to 3As shown, the electric control architecture of the multi-wheel drive electric vehicle of this embodiment includes a driving unit, a power generation unit, a control unit and a data transmission unit. The driving unit drives the electric vehicle, and the power generation unit can recover energy when the electric vehicle is coasting, going downhill and braking, thereby generating electricity and storing electric energy for the driving unit. The control unit realizes the whole vehicle control of the electric vehicle, and the modules of the control unit are independently designed to facilitate maintenance and repair. The data transmission unit can transmit data so that the control unit can control the electric vehicle.

[0038] In this embodiment, the driving unit includes a plurality of driving power supplies to drive the electric vehicle. The driving power supplies of this embodiment are modularly designed. The cruising range of the electric vehicle can be changed by changing the number of driving power supplies, and adjacent driving power supplies are arranged in series.

[0039] Furthermore, the power generation unit of the present embodiment can recover energy from the electric vehicle during riding, and store the recovered energy in a driving power supply. The power generation unit includes at least one generator. The generator of the present embodiment is a chainless generator, which is installed on the frame of the electric vehicle. The generator can generate electricity during the riding of the electric vehicle. During the riding process, about 250W of energy can be added to the entire vehicle body circuit as part of the range extension. In addition, when the electric vehicle is coasting, going downhill and braking, the entire vehicle will recover energy as part of the efficiency improvement.

[0040] In this embodiment, the control unit includes a GCU module, an MCU module, an LCU module, a VCU module, and an IQT module for control and information exchange. The control unit can realize two-wheel, three-wheel, and four-wheel platformization and share a set of products to switch different modules to realize vehicle control. For example, two controllers can be used for two-wheel drive control, and the same four controllers can be used for four-wheel drive control, and the platform can share any frame drive matching mode. The software architecture is also a shared platform. For two-wheel, three-wheel, and four-wheel, multiple-wheel drive software can be used, that is, the drive software architecture of each single wheel is independent, and the software for switching multiple wheels is the same. The VCU module controls and adjusts the independent rotation of different wheels.

[0041] In this embodiment, the GCU module is a generator module, the MCU module is a motor control module, the LCU module is a discharge circuit module, the VCU module is a vehicle control module, and the IQT module is a switch quantity control module. The motor control module of this embodiment includes a left motor control module and a right motor control module, and the two motor control modules control the motors respectively.

[0042] Furthermore, the generator transmits the transmission signal to the GCU module. After receiving the signal, the GCU module transmits the signal to the VCU module, and the VCU module controls the start of the driving power supply to recover energy and perform power generation operations.

[0043] In this embodiment, the data transmission unit includes instrument Bluetooth, controller Bluetooth and IOT module to realize data transmission online or offline. The IOT module of this embodiment is an Internet of Things module, which realizes data transmission online, while the instrument Bluetooth and controller Bluetooth can realize data transmission offline.

[0044] The electric control architecture of the multi-wheel drive electric vehicle of this embodiment also includes a sensor unit, which monitors the driving data of the electric vehicle. The sensor unit includes a steering angle sensor, a pressure sensor and a ramp sensor. The steering angle sensor, the pressure sensor and the ramp sensor are all installed on the frame of the electric vehicle to monitor the driving status of the electric vehicle. The sensor unit transmits the acquired electric vehicle sensor data to the VCU module, and the VCU module performs data compensation and data repair. The steering angle sensor can identify the steering angles of different wheels to meet the synchronization and complementarity of different wheels and the status of different road conditions, such as muddy roads or suspended roads, slipping, etc., and compensation and repair are performed through software. The pressure sensor and ramp sensor are used to identify the load and ramp status of the whole vehicle to give the whole vehicle different ramp forces and powers to prevent slow starting and insufficient power when sliding or carrying a heavy load.

[0045] In summary, this embodiment is aimed at an electric vehicle that can realize human pedaling and achieve the effect of power generation. It can be controlled through a control algorithm. The electric bicycle can generate electricity and recover energy during driving, which can achieve the purpose of extending the range. It can perform battery replacement and multi-battery management to achieve the purpose of long-term operation. Through slope sensors and pressure sensors, the electric vehicle can automatically control uphill starting, riding and braking processes, and automatically control the size of the force of the generator and the drive motor to achieve automatic distribution, thereby improving the riding stability of the electric vehicle.
