When the traction control computer (often incorporated into another control unit, such as the ABS module) detects one or more driven wheels spinning significantly faster than another, it invokes the ABS electronic control unit to apply brake friction to wheels spinning with lessened traction. Braking action on slipping wheel(s) will cause power ...
It monitors individual wheel speeds through the Anti-lock Brake System (ABS) or wheel speed sensors and controls engine inputs to maintain stability and traction to the vehicles wheels. When the traction control system notices wheelspin on any of the wheels it limits the fuel provided through the onboard engine management system and controls ...
The greatest effort is required from a locomotive when starting. At this time, if the engineer applies too much power to the wheels (i.e., for a steam locomotive, the engineer opens the regulator too far) the turning force applied to the wheel will greatly exceed the opposing friction force affected by the surface of the rail, and the wheel will turn without being able to move the train forward.
Many ESC systems also incorporate a traction control system (TCS or ASR), which senses drive-wheel slip under acceleration and individually brakes the slipping wheel or wheels and/or reduces excess engine power until control is regained. However, ESC serves a different purpose from that of ABS or traction control. [31]
The early Packard Twin Traction unit is designed to function in this manner, which was promoted to provide a different benefit: if one rear drive wheel momentarily leaves the ground when it hits a bump with the differential under load, the airborne wheel will not spin freely and cause the vehicle to break traction when the spinning wheel ...
Wheel slide protection and wheel slip protection are railway terms used to describe automatic systems used to detect and prevent wheel-slide during braking or wheel-slip during acceleration. This is analogous to ABS and traction control systems used on motor vehicles. It is particularly important in slippery rail conditions.
Also, in LOCK mode the system senses when wheels on the diagonally opposite corners are in danger of spinning without traction during vehicle operation at low speeds. By activating the brake traction control function at lower speeds than the system in the Outlander, Mitsubishi improved the vehicle's all-terrain performance at low speeds. [23] [24]
A burnout (also known as a peel out, power brake, or brakestand) is the practice of keeping a vehicle stationary and spinning its wheels, the resultant friction causing the tires to heat up and smoke. While the burnout gained widespread popularity in California, it was first created by Buddy Houston, his brother Melson and David Tatum II at Ted ...
