Many people use the words car and vehicle interchangeably, but there is a difference. A vehicle is anything that transports people or cargo, including cars, trucks, trains, boats and planes.
The first engine-powered vehicles were cars, also known as motorcars or automobiles. These vehicles dominated the transportation industry until the 19th century.
Locomotion
Locomotion is the movement t 운전연수 hat enables something to move from one place to another. The word comes from the Latin loco (place) and motio (to move). Typically, vehicles require some form of mechanical power for locomotion, although some animals use a variety of methods. The study of locomotion is important in biology, biomimetics and robotics.
Animals have evolved a wide range of different modes of locomotion, which enhance their success in obtaining food, reproducing, escaping predators and avoiding unsuitable environments. Often, the ability to adapt to environmental restraints such as gravity and drag is essential to locomotion.
The physical restraints on movement are determined by the nature of the environment and the animal’s body shape and composition. In axial locomotion, the nervous system produces rhythmic neuronal activity that drives patterned contractions of musculature. This type of movement is most common in amphibians and aquatic vertebrates, but is also observed in certain insects and some crustaceans.
The type of vehicle used for transporting goods or passengers is determined by the type of terrain to be traversed and the capacity, price and reliability requiremen 운전연수 ts of the vehicle. Most terrestrial vehicles are wheeled, although tracked, screw-propelled and walking vehicles exist. Continuous track, which consists of free-running tires or rollers connected to an endless chain or belt, is used in some vehicles such as tanks and snowmobiles.
Power
Power in vehicles is provided by the engine that creates torque. A vehicle’s engine enables it to accelerate rapidly, overtake other vehicles and transport heavy loads with relative ease. This is why it is important to consider a vehicle’s horsepower and torque specifications when shopping for the perfect car.
Torque is the turning force produced by an engine’s crankshaft and it allows a vehicle to move from a stopped position or up an incline. The energy that is transformed into work is called potential energy or energy of position, and it may be converted to kinetic energy which is the energy of motion.
The difference between horsepower and torque is that horsepower speaks to acceleration while torque addresses load-carrying capabilities. This can be illustrated by imagining that car A has less torque and more horsepower than car B. If you place heavy weights in the trunk of car B, it will be difficult to keep up with car A’s initial acceleration as the engine struggles to maintain its performance.
Horsepower is commonly used to describe a car’s performance while torque is often ignored. For instance, when considering whether or not a car will be suitable for hauling large loads, it would be helpful to take torque into consideration. It is important to understand the difference between these two specifications so that you can make an informed purchase decision based on your specific needs.
Control
The century-old automobile – the preferred mode of personal mobility in developed countries – is rapidly evolving into complex electromechanical systems. Vehicles are being equipped with a variety of modern technologies in order to increase operating safety, reduce traffic congestion and energy consumption, and minimize environmental effect [1].
The control arm is one of the most basic and important components in your car’s chassis system. It manages steering input from the driver and fluctuations from the road surface, ensuring that your car drives smoothly and safely. However, like any mechanical component, the control arm has a limited lifespan and can be damaged by harsh driving or improper maintenance.
An ECU, or Electronic Control Unit, is the heart of a vehicle’s electronics. It holds the base numbers and parameters for every system in the car, and it controls those systems via sensors around the vehicle. Some vehicles have multiple ECUs, while others have a single one that handles many different features.
Traction control (also known as stability control) is another of the most important computer-controlled driver aids. It works similarly to antilock brakes, helping your tires find traction in slippery conditions.
Safety
When the first mass-market automobiles appeared on America’s roads, people assumed that they were safe vehicles. After all, unlike a horse that could easily overturn a carriage, an automobile relied solely on its driver for directions and control. Logic dictated that an inanimate machine could not cause accidents. Instead, public safety depended on improving driver skill and reducing rampant error and recklessness.
In the 1950s, elected officials studied scientific findings from university crash tests and developed a government response to vehicle safety issues. Seat belts, padded dashboards and other features were introduced. These improvements dramatically reduced fatality rates for motorists.
Today, newer cars have more safety options than ever before. Safety technologies such as stability control, which is standard on most new models, save lives by preventing the car from going out of control when driving around a curve. Other advanced features such as forward collision warning and automatic emergency braking can help you avoid crashes.
Some systems, such as GM OnStar, BMW Assist, Kia UVO, and Hyundai Bluelink, combine cellular phone technology with Global Positioning Satellite (GPS) technology to allow you to call a live person at a central dispatch center when the car breaks down or is involved in a crash. Others monitor steering inputs, lane departures and other factors to detect inattention or drowsiness.
