It used to be easy to make your car go faster -- just step on the accelerator, and the throttle would manually open. Today, many cars use electronic throttle control. What does it take for sensors and computers to control a car's speed?
Today, the average new car has between 30 and 80 electronic control systems under the hood. With technology-based recalls making headlines, it's easy to wonder: Is all this technology making cars more dangerous?
German auto supplier Bosch developed the first electronic stability control system in the mid-1990s. Decades later, most cars and SUVs are equipped with electronic stability control as standard equipment.
An electronic brake force distribution system determines the exact amount of brake force required at each wheel during any braking situation. But how does the system precisely modulate the brake force?
Airbags are everywhere. You can find them in the front and on both sides of your car. Vehicles now have tubular airbags, knee airbags and even outside airbags to protect pedestrians. How much safety is too much?
Airbags have saved more than 27,000 lives since 1990, yet they still have detractors because of their danger to children. Occupant Classification Systems detect exactly who -- or what -- is sitting in your passenger seat.
There's always going to be some risk involved with automobile travel. Crash testing helps remove some of that risk. However, given the availability of modern computer modeling, is it still necessary to destroy actual vehicles?
A lot of engineering goes into crash test dummies. But as advanced as crash test dummies are, they can't tell researchers everything that happens in a crash. That's where human crash test dummies come in.
Did you know that parts of your car are built with special structures designed to be damaged, crumpled, crushed and broken? These components redistribute the force of an impact before it reaches the vehicle's passengers.
