How should an electric car be balanced?

Self-balancing electric scooter is a two-wheeled electric vehicle with a self-balancing system with a two-wheeled left and right parallel arrangement structure. The inverted pendulum control principle is used to keep the body balanced at all times. Under the control of the embedded CPU in the car body, the data of the balance sensor and the speed and acceleration sensor are collected, and the PWM signal is calculated and output through the established system mathematical model and control algorithm, and the torque of the two servo motors is automatically controlled, so that the car body is balanced and can automatically move forward, backward and turn according to the offset of the center of gravity of the human body.

Compared with traditional electric scooters, it has the following advantages:

1. The turning radius of the vehicle is zero, and it can move flexibly in a small space;

2. No braking system, the CPU automatically gives forward and reverse torque, so as to achieve fast and stable braking effect; The control is extremely convenient, and you can move forward and backward freely.

3. It can be applied to pedestrian streets, squares, playgrounds and large venues, etc., where cars cannot pass and it is very inconvenient to walk.

The weight of the whole vehicle is about 30 kg. During normal work, personnel can drive it to walk freely after about 10 minutes of training. The car automatically accelerates when the body leans forward and slows down when it leans back.

With the control handle, you can turn in place at any angle. Speeds of up to 10 km/h can be achieved. The continuous mileage is about 30 km.

When in use, turn on the power master switch, the system boots, and the CPU starts to work. When the body balance is stationary, the torque input of the left and right drive wheels is zero. When it is necessary to move forward, the driver leans forward, and the spirit sensor or angle sensor obtains the vehicle inclination angle signal and sends it to the CPU, and the CPU calculates the required torque according to this signal and integrates the signals of the left and right wheel speed sensors and acceleration sensors, controls the wheels to rotate forward and always maintains the balance of the car body.

The greater the inclination, the faster the acceleration. After the inclination angle reaches a certain value, the acceleration stops, and the vehicle moves forward at a constant speed. When it is necessary to decelerate, brake or retreat, the driver leans back, and the CPU can also calculate the size of the required reaction torque according to the signals of each sensor, and control the wheels to generate an appropriate reaction torque to slow down, brake or retreat the vehicle.

When it is necessary to turn, the driver gives a signal by pressing the steering control button, and the CPU calculates the different torque sizes required by the left and right wheels according to the signal characteristics and combines other sensor signals, and can control the rotation of the car body to the desired angle by using the speed difference between the left and right wheels. Thanks to the inverted pendulum control principle of three-dimensional dynamics, the vehicle can always maintain a balanced and stable state in various operating conditions such as forward, backward, braking and turning.

If you just learn the first is to relax and be natural, the turn of the handlebar acceleration is best slow, the two feet are best not to put on the car, you can put it on the ground to keep the car balanced, and then put the feet on the car when the drive is more stable, familiar with the natural will understand the performance of the car, take your time and don't be too nervous, the car keeps driving slowly, don't accelerate when you need to stop, just brake.

Feel which way the car is falling, twist the halter a little bit, and master the amplitude of the twist, practice more!

There are many reasons why you can't maintain your balance while riding an electric car, and the more common ones are nervousness, slow speed, poor vision, and improper sitting posture. In addition, if there is a problem of ear fluid imbalance, riding an electric car is also more affecting the balance, which is more difficult to solve, and it is not something that can be solved through practice, and it needs to be carried out in time.

Overcome psychological problems.

This is important, and this is a two-pronged issue. The first thing is that you have to be brave enough, when you first learn to ride a bike, you will definitely fall down a lot, you have to have the spirit of not being afraid of falling, and you have to get up from there if you fall down from there.

In addition, you must have the spirit of not being afraid of losing face. You may feel ashamed because you will often fall down in the process of learning, and even have the idea of giving up, so you have to learn it "cheekily".

When practicing cornering, you should master the conversion of the throttle, 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 will definitely feel less coordinated, and you may remember the movements of the right hand, and you may forget the movements of the left hand, but as long as you practice diligently, you will overcome them.

The balance trick of riding an electric car is: relax your body, don't be too nervous, don't use too much force to grab the handlebars, if you grab the handlebars too hard, your hands will be sore for a while, and the handlebars will be unstable. Keep driving at a constant speed, never screw the throttle knob to the head, slow speed in the early stage, keep it at about 10-20km, and practice slowly for a few days.

Keep a relatively safe distance between the car, and the car and pedestrians must keep a safe distance from the car and pedestrians, after all, it is the beginner stage.

Because the electric car is two-wheeled, it can't stand when it doesn't move, and it can only be balanced by inertia when driving, and if you haven't learned to ride a bicycle before, it will take a few days of contact to master the balance.

Learn the method of mastering the balance of electric vehicles, and the whole course of teaching for women is as follows:

1. Don't grab the handlebar too hard with both hands.

If you hold the handlebars too hard, your hands will be sore for a while, and the handlebars will be unstable. Hold the handlebar naturally with both hands, take it easy, and you will control the car well.

2. Drive carefully, the speed of the electric car should not be too fast.

Electric brakes are not very good, and even if you hold the brake lever with both hands in time, the car will still rush forward for several meters, so be sure to drive carefully.

3. When practicing balancing, keep the car upright and start the throttle slowly.

Turn the throttle slowly, grasp the increase or decrease of the throttle, and ensure that the car has enough power. If the throttle is too low, the car will easily stagger, and the balance will be difficult to maintain.

4. When practicing cornering, you should master the conversion of the throttle, and you can adjust the speed appropriately.

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. In case of an emergency, pinch the handle of the emergency brake.

Stupid people learn the trick of riding an electric car:

Before learning about electric vehicles, you must first understand its basic functions, aside from the light operation, the main control of the electric vehicle driving process is the accelerator and brake, as follows:

1. The left handle lever is the rear wheel brake, and the braking is mainly the rear brake during driving.

2. The right handle lever is the front wheel brake, the braking performance is not as good as the rear wheel, and it is mostly used in auxiliary braking after deceleration, and the effect of deceleration is increased.

3. The side handle is the throttle, and the more you twist it inward, the more power it will have.

First of all, you need to be bold and careful, try to correct the faucet when starting, move forward naturally after starting, slowly lift the speed, control the speed at about 15-20 yards at the beginning, keep driving at a constant speed, practice controlling the body to drive steadily, when you practice many times and feel that it has been very natural and smooth, when there is no psychological pressure, you can try to raise the speed, and when the speed is faster, you can also adapt, and then try to start continuously - speed up - deceleration or sudden braking - re-acceleration, etc., The road section selected in front is best to be smoother and less personnel and vehicles, and then try the road section with more people or vehicles after many times of practice, and slowly you can drive at will on the whole road section, and you can avoid overtaking can be handy.

Hello, happy to answer your questions.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! If you want to have a sense of balance in this electric car, you must first look ahead, not left and right. Then hold the steering wheel with both hands so that the car is in normal driving, that is, all the time walking in this state to look ahead, the direction to straighten, so that the sense of balance comes out, and then you ride, this direction is straight If you ride for a long time, you can turn, these are more proficient.

Make good use of the throttle to boost, don't blindly rely on the feet and brakes, let the car move, you can naturally get enough balance, the less power you have, the worse the balance.

If you can quickly learn to ride an electric car and master your balance, you can first practice walking on a single-plank bridge, or tie some bamboo poles to the battery car, so that you can find a sense of balance.

Start by taking a bicycle and practicing your hands.

Don't you know how to ride a bike?

Riding an electric car is the same as riding a bike.

Alone in a foreign land as a stranger, every festival is full of relatives.

The remote knowledge brothers ascended to the heights, and there was one less person in the dogwood.
