The most common wheel speed sensor system consists of a ferromagnetic toothed reluctor ring (tone wheel) and a sensor (which can be passive or active). The tone wheel is typically made of steel and may be an open-air design, or sealed (as in the case of unitized bearing assemblies). The number of teeth is chosen as a trade-off between low-speed ...
The desired vehicle state is determined based upon the steering wheel angle, its gradient, and the wheel speed. Simultaneously, the yaw sensor measures the vehicle's actual yaw rate. The controller computes the needed brake or acceleration force for each wheel and directs the valves of the hydraulic modulator.
HTV-2 (artist rendering), the fastest uncrewed aerial vehicle. North American X-15, the fastest piloted rocket-powered aircraft. SR-71 Blackbird, the fastest piloted air-breathing aircraft. Rare Bear, the fastest piston-engined aircraft. Musculair 2, the fastest human-powered aircraft.
Definitions. In the broad sense, specific "rolling resistance" (for vehicles) is the force per unit vehicle weight required to move the vehicle on level ground at a constant slow speed where aerodynamic drag (air resistance) is insignificant and also where there are no traction (motor) forces or brakes applied.
The driver must manually bring the vehicle up to speed and use a button to set the cruise control to the current speed. The cruise control takes its speed signal from a rotating driveshaft, speedometer cable, wheel speed sensor from the engine's RPM, or internal speed pulses produced electronically by the vehicle. Most systems do not allow the ...
A digital, LCD speedometer in a Honda Insight. A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards. [ 1 ]
Dynamic steering response (DSR) is a vehicle safety and advanced power steering system that can counteract unstable or difficult steering that may be caused by external forces such as strong crosswinds or uneven roads by giving proper steering assistance from the steering gear. [1] DSR assists the driver by determining the correct steering ...
The land speed record (LSR) or absolute land speed record is the highest speed achieved by a person using a vehicle on land. By a 1964 agreement between the Fédération Internationale de l'Automobile (FIA) and Fédération Internationale de Motocyclisme (FIM), respective governing bodies for racing in automobiles and motorcycles (two or three ...
