The basic composition of the integrated control system of the automobile power transmission system
Tumblr media
The function of the control system is to automatically adjust the transmission ratio and working status of the basic transmission components according to the driver's intention and     Adani Gujarat    the changes in the vehicle driving environment, to achieve the best transmission efficiency and the best overall vehicle performance. The vehicle control system is mainly composed of three parts: the vehicle data acquisition system (sensor part), the electronic control unit, and the actuator.
The composition of the vehicle data acquisition system (sensor part). In the entire control system, part of the role of the sensor is equivalent to the driver's visual, auditory, and tactile system in the case of manually operating the shifting vehicle, collecting, and transmitting various parameter signals required for shifting to the electronic control unit.
The vehicle runs and works according to the driver's intention, and the vehicle control system must be able to correctly recognize and implement the driver's manipulation. The recognition of the driver's intention is to test the changes of the vehicle control mechanism (such as accelerator pedal, brake pedal, steering wheel angle, etc.) through sensors, and obtain through analysis.
The sensors used in automobiles mainly include the following types:
 magnetoelectric sensors, magneto resistive sensors, photoelectric sensors, Hall sensors, thermal sensors, varistor sensors, piezoelectric crystal sensors, etc. The sensors used in the transmission part of the power transmission system mainly include engine speed sensor, vehicle speed sensor, throttle opening sensor, clutch displacement sensor, etc.
 Among them, the engine speed sensor and the vehicle speed sensor use magnetoelectric sensors and Hall sensors, and other sensors that use the principle of magnetoelectric signals. The throttle opening sensor and the clutch displacement sensor both use rheostat sensors. In addition to sensors, other signals are transmitted through switches and controllers or other methods. Commonly used switches include multi-function switches and forced low-shift switches. The switch is also a very important means of signal input.
Electronic control unit. The electronic control unit (ECU) is the core of the entire control system. Its function is based on the driver's intention and the signal detected and provided by the vehicle's motion state parameters to carry out gear shifts or working state changes. The main functions of the electronic control unit are: signal acquisition and preprocessing, driver manipulation intention recognition, vehicle status recognition, shift decision (shift schedule), shift quality control, fault diagnosis function, output, and display functions.
The new generation of controllers has comprehensive functions and very good control performance. It uses high-performance 16-bit or 32-bit microprocessors, and some even use custom-made microprocessors, which contain most of the functions required for control and simplify control of the circuit and enhance the function and reliability of the circuit. As the controller's microprocessor is updated, the shift control is more complicated, and the processor's peripheral circuit expansion makes the input and output functions more powerful. In order to achieve greater improvement in control performance, not only control programs are used in these controllers, but also embedded real-time operating systems are used.
Executive agency. After the control system samples and obtains the input signal, it is sent to the controller for data processing. After the data processing is completed, control signal No. 1 of the electronic control unit will change the working state of the power transmission system through the actuator to ensure the proper performance of the vehicle. At the same time, the actuator guarantees the control of shift quality. The actuators that realize gear switching generally use solenoid valves.
The composition of the transmission system: The mechanical transmission system is mainly composed of clutch, transmission, universal transmission, and drive axle. The universal transmission device is composed of a universal joint and a drive shaft, and the drive axle is composed of the main reducer and a differential. The hydromechanical transmission system is mainly composed of a hydraulic torque converter, an automatic transmission, a universal transmission, and a drive axle.
The function of the transmission system: Deceleration and torque increase: The power output by the engine has the characteristics of high speed and low torque, which cannot meet the basic needs of car driving. Through the main reducer of the transmission system, the purpose of deceleration and torque increase can be achieved, which is transmitted to the driving wheels. The lower torque of the engine is converted to higher torque of the drivetrain.
Variable speed and torque: The optimal working speed range of the engine is very small, but the speed of the car and the resistance that needs to be overcome vary in a wide range. Through the transmission system, the working range of the engine can be expanded, thereby meeting the demands for large changes in the driving speed of the car and overcoming various driving circumstances and resistance.
Reversing: The engine cannot be reversed, but in addition to forwarding, the car needs to reverse. If the reverse gear is set in the transmission, the car can reverse. Interrupt the power transmission of the transmission system when necessary: When starting the engine, shifting gears, stopping for a short time during driving (such as waiting for a traffic light), or car sliding at low speed, it is necessary to interrupt the power transmission of the transmission system. The neutral gear can interrupt the power transmission.
Differential function: In the case of car steering, etc., the two driving wheels need to be able to rotate at different speeds, and the differential function can be realized through the differential in the drive axle.

Solar energy pros and cons in 2021
Tumblr media
If you’re looking to install solar panels on your home, you’ll find a wide range of information. This can  Adani Gujarat   make it difficult to figure out whether or not solar panels are the right fit for you.
To help you out, we’ve put together a conclusive list that weighs the pros and cons of solar.
Solar energy pros and cons Looking at the advantages and disadvantages of solar energy from a homeowner's perspective is an important step in the research process when considering installing solar panels for your home.
The argument for the average American homeowner to install solar panels for their home is now better than it has ever been, as the benefits far outweigh the drawbacks.
Let’s take a closer look at each of these solar energy pros and cons.
Advantages of solar energy 1. Reduces your electric bill One of the biggest benefits of solar panels is that they can provide you substantial savings on your electric bill. Many states require utilities to offer net metering, which allows homeowners to offset their electric costs with the energy their solar panels produce.
They can then sell that excess energy to the utility. This will usually be added onto their electric bills as a credit that can then be used to offset future electricity costs.
In many states, adding solar panels to your home can bring in electric bill savings of well over $1,000 per year. Residents of California who go solar save an average of $99,181 over the lifetime of their solar system!
2. Insurance against rising power prices One thing most homeowners know is that electricity keeps getting more expensive. The price of electricity has increased steadily over the past 10 years, with an average increase of about $0.2 per year. The cost of electricity will continue to rise into the future, meaning your electric bill will continue to go up too.
Solar panels protect you from these rising electricity costs. Because you are producing your own energy, you don’t have to buy that expensive power from your utility. So, rising electric costs are a worry of the past! In fact, rising prices might actually be a good thing when you install solar.
For example, let’s say your utility charges 12 cents per kilowatt hour of electricity. That means with net metering, your utility would pay you 12 cents for each excess kWh of electricity your solar panels produce and send to the grid.
If your utility raises its electricity price to 13 cents per kilowatt hour of electricity, that means the power you send to the grid would also be worth 13 cents.
So, net metering is saving you more money each time your utility raises their prices!
3. Solar is cheaper than ever While electricity prices continue to get more expensive, the cost of solar has continued to fall. Solar is now cheaper than ever; in fact, the cost has fallen over 70% in the past decade. These low prices make solar more accessible to more homeowners than ever before.
Installing solar can be even cheaper when you take advantage of solar incentives. For example, if you install a solar system before the end of 2022, you could be eligible for the 26% federal tax credit.
This tax credit is equal to 26% of the total cost of your solar system and is applied to your income taxes. In addition to the federal tax credit, there are many other solar incentives offered locally.
Find out how much you can save on solar with local incentives in your area 93305 4. See return on your investment Solar panels not only eliminate your electric bill, they can also be a source of extra income. As we mentioned before, net metering allows you to earn money by selling excess power your solar panels generate to your utility.
Some states have other performance-based incentives, like Solar Renewable Energy Credits (SRECs), that have the potential to earn you hundreds of dollars a year, depending on where you live.
The money you earn from net metering, combined with your electric bill savings and other incentives, goes towards paying back the cost of your system. In areas that have all of these incentives, the payback time for a solar panel system can be as little as four years.
Once your system is paid off, your solar panels will continue to generate free power for your home for the lifetime of the system!
5. Environmentally friendly Another big selling point for solar is that it is a renewable energy source. This means that as you use the resource, it doesn’t deplete the source. So, by using the sunlight that hits the earth and turning it into electricity, we don't deplete the sun’s energy.
Plus, electricity created with solar panels does not produce any greenhouse gas emissions. Nothing is being released into the atmosphere when we produce electricity with solar panels. The only thing that's created is clean energy!
