A rear-end collision, often called rear-ending or, in the UK, a shunt, occurs when a forward-moving vehicle crashes into the back of another vehicle (often stationary) in front of it. Similarly, rear-end rail collisions occur when a train runs into the end of a preceding train on the same track . [ 1 ]
"Sudden acceleration incidents" (SAI) are defined for the purpose of this report as unintended, unexpected, high-power accelerations from a stationary position or a very low initial speed accompanied by an apparent loss of braking effectiveness. In a typical scenario, the incident begins at the moment of shifting to "Drive" or "Reverse" from ...
Forward collision warning (FCW) combined with automated emergency braking (AEB) reduced the incidence of rear-end collisions by 49 percent. It's not just low-speed crashes that are prevented—the ...
Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. [1] [2] [3]
The rear wheels are located transversely by top links and wheel carriers (green) and lower links (cyan). The top link is the driving half-shaft with a universal joint at each end. The lower link pivots adjacent to the differential casing at its inboard end and where it meets the wheel carrier at the wheel hub casting (violet) at its outboard end.
Differential unit for a rear-wheel drive car, built by ZF c. 2004 Differential gears (in yellow) in a punched tape reader, built by Tally c. 1962 A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others.
Driving etiquette refers to the unwritten or unspoken rules that drivers follow. [ 1 ] [ 2 ] [ 3 ] The term dates back to the early 1900's and the use of horse-drawn carriages . [ 4 ] Driving etiquette typically involves being courteous and staying alert, which varies by vehicle, situation and location (e.g., etiquette for driving an F-1 race ...
