What does a self balancing two wheeled electric vehicle rely on to master the balance

The rider intelligent balance bike will answer for you: the operating principle of the balance bike is mainly the principle of aircraft balance, that is, the automatic balance ability of the vehicle itself (electronic self-balancing system). When a person steps on the pedal, there is a sensor under the pedal, and a precision electronic gyroscope is placed to judge the posture of the body, and the appropriate instructions are calculated through the precise and high-speed ** microprocessor, and the motor is driven to achieve the effect of balance.

Suppose we use the longitudinal axis of the driver standing on the car and the overall center of gravity of the vehicle as the reference line. When this axle is tilted forward, the built-in electric motor in the body of the balance car will produce forward force, on the one hand, it balances the torque of the person and the car to tilt forward, on the other hand, it produces the acceleration of the vehicle forward, on the contrary, when the gyroscope finds that the driver's center of gravity is leaning backwards, it will also produce backward force to achieve the balance effect. Therefore, as long as the driver changes the angle of his body to lean forward or backward, the balance car will move forward or backward according to the direction of inclination, and the speed is directly proportional to the degree of inclination of the driver's body.

In principle, as long as the balance bike has the correct power turned on and can maintain sufficient power, the occupants of the car do not have to worry about the possibility of tipping and falling, which is very different from scooters and other vehicles that generally need to be balanced by the driver himself. <>

I think I should rely on the gyroscope inside to keep it balanced.

Balance with a gyroscope.

There are two high-speed rotating discs in the car, and the centrifugal force of the inductor adjusts its tilt angle through the sensor, and also achieves the purpose of rebalancing.

1.The first prerequisite for learning electric vehicles is to have a good balance in the car. For cyclists, it is not very difficult to grasp the balance, at this time, you only need to turn the throttle slowly, master the increase and decrease of the throttle, and practice to master.

If you don't know how to ride a bike, it will naturally take longer to learn, so you have to practice your balance first.

2.When novices practice balancing, keep the car upright and start the throttle slowly, but make sure that the car has enough power, if the throttle is too low, the car is easy to crook, and the balance is difficult to maintain. It may seem difficult to grasp the speed of the car at first, but as long as you practice diligently, you will be able to master it well.

3.When practicing cornering, you should master the throttle change, and you can slow down appropriately. In case of an emergency, pinch the handle of the emergency brake.

At the beginning, the hands and feet feel less coordinated, and the movements of the right hand are memorized, and the movements of the left hand may be forgotten, which are all signs of novices, but as long as you practice a lot, you will overcome them.

It's the same with a bike.

Normal brush controller.

The controller is the brain of the electric vehicle, which can realize all the functions of the electric vehicle, such as speed regulation, brake power failure, under-voltage protection and internal control, such as over-temperature protection, over-current protection, loss of phase protection, etc.

Electric vehicle controller is divided into brush controller and brushless controller, brush controller structure is relatively simple, change the line is also relatively easy, although the controller lead out of the wire is more or less, but there are several lead wires are fixed, including: two power lines (red and black turn bar line three (red and blue black brake off wire (white and black motor line (yellow and blue line color is summarized according to the commonly used type, the specific situation is specific rolling rubber analysis. The red and black power supply is fixed (the red positive electrode and the black electrode are the negative large side electrodes), and all the black wires are common negative electrodes.

Brushed controller lead parameters.

In the case of power-on: the voltage between the red and black of the handlebar wire is 5V, usually three wires are on one plug-in, which is easier to identify. There are two brake wires on one plug-in, one of which is a black wire.

Generally, there is a lead introduction on the controller manual, and I will not repeat it below. Other auxiliary leads are: (take 36v as an example) 36v lead-out booster lead-out.

Some controller power access wires have three on a plug-in, due to the messy wire, the basic judgment method is black for the negative pole, the other diameter of the wire for the battery positive, the remaining one for the electric door lock outlet, (common positive).

Internal structure The internal structure of the controller is relatively complex, the maintenance cost is high, and the maintenance value is not large.

1. The car is in the process of riding. The center of gravity shifts to the left and right of the rear wheel, acting as a sine wave around your rut.

2. A gyroscope is implanted in the car, and the center shift of the left and right can be extracted into a sine wave signal. After the digital processing of inverted phase, the motor is driven, and the faucet of the car can be adjusted in the opposite direction in time.

3. When turning, you can adjust the offset in time, and you need to send the speed information to the CPU at the same time. This data must be drawn from the driving practice of the car. Write to the ROM.

4. If you can do self-learning, it will be the highest level.
