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 ...
An electronic speed control follows a speed reference signal (derived from a throttle lever, joystick, or other manual input) and varies the switching rate of a network of field effect transistors (FETs). [1] By adjusting the duty cycle or switching frequency of the transistors, the speed of the motor is changed. The rapid switching of the ...
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow ...
When in Engine Control Room mode the bridge handle sends a telegraph signal to the ECR and the ECR handle controls the set point of the control system. In local control, the remote control system is inactive and the bridge handle sends a telegraph signal to the local control position and the engine is operated by its manual controls in the ...
Many of the subsystems in a rail vehicle, such as a locomotive or multiple unit, depend on a reliable and precise rotary speed signal, in some cases as a measure of the speed or changes in the speed. This applies in particular to traction control, but also to wheel slide protection, registration, train control, door control and so on. These ...
One’s biological age, which measures the body’s physiological state, may help predict who is at risk for developing colon polyps, a known risk factor for colorectal cancer.
Speed control/Velocity constant - dynamometer holds the set speed regardless of force or other parameters. For example, if a vehicle tries to accelerate in this mode, dynamometer applies opposite force to maintain set constant speed. This mode is used for example in the static power measurement.
