The operating principle of technical principles is mainly based on a basic principle called "Dynamic Stability", which is the automatic balancing ability of the vehicle itself. The built-in precision solid-state gyroscopes are used to determine the posture status of the vehicle body. After calculating appropriate instructions through a precise and high-speed central microprocessor, the motor is driven to achieve balance&Nbsp; The electric balance vehicle system often uses a brush DC motor or a brushless DC motor. The brush motor is characterized by fast starting, sensitive braking, smooth speed regulation over a large range, simple control circuit, and is suitable for general power equipment. It can work continuously for 5000 hours, with a normal lifespan of two to three years. However, if it works continuously for 1000 hours, the carbon brush needs to be replaced; Brushless motor is an integral part of the motor and driver, without the need to replace the brush. It is an electromechanical integrated device that can operate continuously for 20000 hours with a conventional lifespan of seven to ten years. Digital frequency control speed regulation is easier, and the power consumption is one-third of that of a brush motor. However, high cost requires high control accuracy, making it suitable for equipment with high speed control requirements&Nbsp; In the electric balance vehicle system, to obtain acceleration and angular velocity information, the acceleration sensor can convert the acceleration generated during human motion into a signal for effective processing, thereby determining the actions made by the human body; The gyroscope can convert the rotational angular velocity of the electric balance vehicle into a signal, and the integral processing of the rotational angular velocity corresponds to the tilt angle of the balance vehicle, thereby controlling the balance of the electric balance vehicle&Nbsp The design of a two wheel self balancing electric vehicle mainly has the following characteristics:; Green and environmentally friendly. Electric vehicles are powered by batteries, completely pollution-free to the environment, absolutely green and environmentally friendly, and can be recharged and used repeatedly. Moreover, the operating efficiency of the electric motor is high, and the noise efficiency is low, which not only reduces noise pollution but also saves energy&Nbsp; The turning radius is very small, basically close to 0. This is very suitable for use in small spaces. For example: large shopping malls, small paths, talent markets, workshops, etc&Nbsp; No brake system, where the gyroscope detects the angular velocity signal, the accelerometer detects the angular signal, and then fuses to obtain the precise angle signal of the two wheel electric balance vehicle. Finally, it is transmitted to the microcontroller, where the PWM module of the microcontroller controls the forward and reverse rotation of the motors of the two wheel electric balance vehicle. This not only avoids energy waste, but also avoids wear on the brake pads. Traditional cars may also experience poor braking, which is not a concern on two wheel electric balance vehicles&Nbsp; The control is extremely convenient, and the forward, backward, and running speed of a two wheel electric balance vehicle can be changed simply by tilting the body forward and backward, which is much more convenient and flexible than traditional cars. In real life, two wheel electric balance vehicles have been adopted in some special industries, such as the "Segway" driving on the streets of Beijing during the 2008 Olympics. When police officers encounter suspicious situations, they can react very quickly, thereby effectively improving work efficiency
