Embodiment Construction

[0067] see figure 2 , the invention provides an electric bicycle intelligent control system, including a motor unit, a control unit and a power unit;

[0068] Motor unit: It is composed of brushless DC motor, current sensor and rotor position sensor. In the simulation or hardware experiment, the detection position of the current sensor can be adjusted at any time to adapt to the application of different control strategies.

[0069] Control unit: It belongs to the weak current part; it adopts the "DSP+ARM" architecture, which is used to realize fault isolation, fault-tolerant control strategy and other functions, and complete the communication between processors and between processors and host computers.

[0070] The division of labor between the two processors is: DSP is responsible for the conventional double closed-loop control of the motor, coordinated control and fault-tolerant control strategy, and controls the power circuit unit, and sends the running status data to th...

Abstract

The invention discloses an electric bicycle intelligent control system and a control method thereof. The system comprises a motor unit, a control unit and a power unit. DSP+ARM architecture is employed for the control unit. The control unit is used for realizing fault isolation and fault-tolerant control policy functions and finishing communication between processors, and between the processors and an upper computer. An IGBT three-phase full-bridge inverter is employed for the power unit. The motor unit comprises a brushless direct current motor, a current sensor and a rotor position sensor. The control unit is connected with the brushless direct current motor through utilization of the IGBT three-phase full-bridge inverter. The current sensor and the rotor position sensor are used for collecting signals of the brushless direct current motor and are connected with the control unit through utilization of signal and communication interfaces. According to the system and the method, an electric bicycle is enabled to be driven stably, adapt to various road conditions and have very high safety and anti-theft coefficients.

Description

technical field [0001] The invention belongs to the technical field of electric bicycle control, and in particular relates to an electric bicycle intelligent control system and a control method thereof. Background technique [0002] An electric bicycle refers to a mechatronic personal vehicle that uses a battery as an auxiliary energy source on the basis of an ordinary bicycle, and is equipped with operating components such as a motor, a controller, a battery, a handlebar, and a display instrument system. [0003] The development of China's electric bicycles has three stages of development: the primary stage of electric bicycles, the initial stage of large-scale production, and the stage of overspeed development. From 1995 to 1999, the initial stage is also known as the early experimental production stage. This stage is mainly to explore and study the key technologies of the four major parts of electric bicycles, motor, battery, charger and controller. In the early days of...
