Crumple zone. A crash test illustrates how a crumple zone absorbs energy from an impact. The crumple zone on the front of these cars absorbed the impact of an offset head-on collision. Crumple zones, crush zones, [1] or crash zones are a structural safety feature used in vehicles, mainly in automobiles, to increase the time over which a change ...
The terms "active" and "passive" are simple but important terms in the world of automotive safety. "Active safety" is used to refer to technology assisting in the prevention of a crash and "passive safety" to components of the vehicle (primarily airbags, seatbelts and the physical structure of the vehicle) that help to protect occupants during a crash.
Vehicle safety technology (VST) in the automotive industry refers to the special technology developed to ensure the safety and security of automobiles and their passengers. The term encompasses a broad umbrella of projects and devices within the automotive world. Notable examples of VST include geo-fencing capabilities, remote speed sensing ...
Electronic stability control (ESC), also referred to as electronic stability program (ESP) or dynamic stability control (DSC), is a computerized technology [1][2] that improves a vehicle's stability by detecting and reducing loss of traction (skidding). [3] When ESC detects loss of steering control, it automatically applies the brakes to help ...
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics. It may be applied for motorized vehicles (such as ...
Seat belt. Buckling a three-point seat belt. A seat belt, also known as a safety belt or spelled seatbelt, is a vehicle safety device designed to secure the driver or a passenger of a vehicle against harmful movement that may result during a collision or a sudden stop. A seat belt reduces the likelihood of death or serious injury in a traffic ...
The Euro NCAP vehicle safety rating encourages manufacturers to take a comprehensive approach to occupant safety; a good rating can only be achieved by combining airbags with other safety features. [122] Almost every new car sold in Europe is equipped with front and side airbags, but in the European Union in 2020 [123] and in the United Kingdom ...
An anti-lock braking system (ABS) is a safety anti- skid braking system used on aircraft and on land vehicles, such as cars, motorcycles, trucks, and buses. [1] ABS operates by preventing the wheels from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over ...
