CAR SAFETY
Active and Passive:
Car safety features are grouped into two categories: Active and Passive.
Active feature are designed to reduce the likelihood of a crash. Things such as tires, brakes, lights and steering are active features. The most important of all of them however is the driver.
Passive safety features aim to reduce the damage done to a car’s occupants in the event of a crash. These include things like seatbelts, airbags, and crumple zones.
For all these features any car can still crash so this report aims to make you more aware of the safety aspects of modern cars and what role they play in driving.
Active Safety Features
Brakes:
The brakes play one of the most important roles in overall safety and so it important that they are reliable and durable.
A good braking system always stops the car in the minimum distance possible while remaining stable, have a constant response which is consistent with brake pedal pressure and let you easily control the car while braking.
Disk and drum brakes are the two types used in cars. Drum brakes are very good to have on your rear axel but not as effective on the front where better balance and heat dissipation is a must.
Heat dissipation is the brakes ability to get rid of the immense amount of heat created by the friction between the brake surface and frictional pads. This is very important since it reduces the amount of friction that can be applied (brake fade) and it can boil the brake fluid rendering the brakes completely useless.
Disk brakes can dissipate heat much more effectively and therefore are much better when you brake often or at high speeds. The best disk brakes are ventilated.
ABS:
ABS (Anti-lock Braking System) is a system which stops the wheels locking up into a skid when braking on slippery surfaces. It works by using a computer which monitors wheel speeds and drives pistons which alternatively increases and decrease brake pressure several time a second on individual wheels when it senses they are about to lock up.
Preventing skidding during braking increases the drivers control of the car and greatly reduces the chance of a crash.
Stability and Handling:
A car with good handling and stability is much safer to drive than a poorly designed one. This is because it grips better and is more responsive.
Good stability and handling is achieved with a combination of suspension, steering, acceleration, brakes and weight distribution.
Due to the high demands of the consumers, there had to be changes made in order to provide a flawless driving experience. Past systems did a wonderful job at reducing the shock and swaying of vehicles, but there is always room for improvement. Premium versions of vehicle suspension are typically found on most luxury vehicles due to the time and cost that is needed to install them. Brands such as Lexus, Mercedes, Ferrari, and Audi are a few that have advanced suspension
Firstly, Virtually all current production vehicles' published road braking performance tests indicate stopping distances from 60 miles per hour that are typically 120 to 140 feet, slightly less than half of the projected safety distances. However, these figures are probably achievable, but they are not realistic and certainly not
Without a reliable and durable steering system the car could veer out of control endangering the driver, passengers and anyone around the vehicle. This means that the steering system has to be virtually perfect. There are two main types of steering systems the basic set up and then there is rack and pinion. The basic set up for steering a car involves a steering wheel, connecting rods, a gear box and the steering knuckle. This system takes the rotation of the steering wheel (and thus the steering rod) and via the gear box transforms the direction of the rotation 90 degrees so that when a rod is attached to the gear box the rotational motion is changed into a back and forth motion.
Any little jerk or a slight movement of the wheel can send the driver hurling into the wall or even another car. It takes a serious amount of focus and skill to be able to endure the conditions that drivers do for hours on
...ture a risk-taking species. In ancient times we took risks just to eat. Later we took huge risks by setting out in little wooden ships to explore the earth's surface. We continued as we sought to fly, travel faster than the speed of sound and to head off into space. We rely on increasingly more complex equipment and constantly strive to design and manufacture faster and even more elaborate devices. It goes without saying that every effort is made to ensure our "safety"; to keep us from harm or danger. Every time you slide behind the wheel of your vehicle you are taking a risk. Driving is the riskiest activity in our lives. It is an inherently "unsafe" environment. The most perfect vehicles on the best designed highways on beautiful sunny days driven by fallible human beings crash into each other. The only way to drive "safely" (as we are all admonished to do!) is to learn more about the process. Learn more about your vehicle and how to maintain it; learn how to use your eyes to look far down the road; learn to spot problems before they happen; and also learn to deal with emergency situations. In most cases it's the human element that fails. After all, safe is only as safe does.
To ensure stable handling, electric power steering works effectively with suspension system comprising MacPherson strut, coil spring in front and twist beam with coil spring in rear. With improved water wading capabilities the car is efficient enough in getting rid of flooded lanes and pit holes, the telescopic double acting hydraulic shock absorber helps in doing so. The discs brakes are further accompanied with Anti-Lock Braking System (ABS), Electronic Brake-Force Distribution System (EBD) and Brake Assist (BA) to provide effective braking in varied
Since the automobile was first created, more and more safety precautions have been taken to make an automobile ride as safe as possible. I will provide information on how to keep you and your car up to date with some precautions to ensure safety on the road.
There are many different types of suspension systems that are used in cars today, and some that were discontinued due to their uselessness. One example of an older suspension system is called the swing axle suspension. This is a very old type, used in many sports cars in the 50’s, but had disappeared for about 2 decades. This was due to the weakness of the system. The handling was awful, as the camber angle can be noticeably changed by a simple bouncing motion, and the change of the static weight and body roll as the car took a corner. The only advantage to this type of system was that it could provide independent shock absorption. (Wan)
I mentioned on the last page that we must stop the bike by turning its kinetic energy into friction. To do this, the brakes apply a force to the disk with pads. The force of this friction is equal to the total downward force (f) that the pads put on the disk(the pads are usually on each side of the disk and crush it between them) multiplied by the coefficient of friction(u).
amount of pressure needed to brake the car your driving. Also you always want to
The average driver doesn’t think about what keeps their car moving or what keeps them on the road, but that’s because they don’t have to. The average driver doesn’t have to worry about having enough downforce to keep them on the road or if they will reach the adhesive limit of their car’s tires around a turn. These are the things are the car designers, professional drivers, racing pit crews, serious sports car owners, and physicist think about. Physics are an important part of every sports and racing car design. The stylish curves and ground effects on sports cars are usually there not just for form but function as well allowing you to go speeds over 140 mph in most serious sports cars and remain on the road and in reasonable control.
Brake assist system (BAS) or emergency brake assist(EBA) is an automobile braking technique which is used to increase the braking force in emergency situation. Brake assist is an active safety system .which is developed by Daimlaer-benz and TRW/Lucas varity in 1990’s.the simulations shows that more than 90% drivers fail to sufficient amount of brake in an emergency situation.
braking system slow, so the riders don’t go into shock, but fast enough to be fully stopped before
Cars general work with the engine turning over from the driver using their key which makes the four piston strokes start. Once that happens, it starts moving getting hot and while that is happening, it moves the transmission belt which moves the alternator, and the alternator starts generating power through kinetic energy which in turns keeps the battery powered so you don’t lose power while driving. After the engine does that then power is supplied to the various computers in the car which gets it started moving. The steering wheel is attached to a steering column and the several other parts of the steering linkage so steering is possible. The brakes have two different types on the front there can usually be disc rotors which work by the rotor being mounted on the rotor hub and held in place with the mounting bracket on the mounting bracket are brake pads which squeeze the rotor which cause the car slow down or stop. The brakes on the rear are drum brakes which are similar to disc brakes, but they have brake shoes which expand to stop or slow down the car. This is not always true though some cars just have disc brakes and some older cars have drum brakes the reason for this is because disc is more reliable than drum brakes. Of course after all that you would remove the key and it would then stop the engine and the belt from turning and then the majority of the electrical stuff turns off except for the battery.
The clutch or brake characteristics are determined by the upper limits of engaging a braking torque, as described in the section on torque characteristics. Load torque beyond that causes slipping at the frictional surface. Knowing these differences in characteristics from the beginning enables you to select the clutch or brake suited for your load conditions. A clutch/brake that has a torque value that is 200 to250% of the full load torque of the motor will normally be suited to a wide range of applications, factoring in reasonable safety considerations when selecting it.
