Cruise control (also known as speed control, cruise command, autocruise, or tempomat) is a system that automatically controls the speed of an automobile. The system is a servomechanism that takes over the car's throttle to maintain a steady speed set by the driver.
In combined-function installations, the lights produce brighter red light as stop lights and dimmer red light as rear position lights. Regulations worldwide stipulate minimum intensity ratios between the bright (stop) and dim (position) modes, so that a vehicle displaying rear position lights will not be mistakenly interpreted as showing stop ...
The ECM is a type of electronic control unit (ECU), which is an embedded system that employs software to determine the required throttle position by calculations from data measured by other sensors, including the accelerator pedal position sensors, engine speed sensor, vehicle speed sensor, and cruise control switches.
Most of the GPS data would procure speed information, but additional speed limit traffic signs can also be used to extract information and display it in the dashboard of the car to alert the driver about the road sign. This is an advanced driver-assistance feature available in most high-end cars, mainly in European vehicles.
Speed appropriate to the hazard being approached, attained via explicit braking or throttle control (engine braking), always being able to stop in the distance you can see to be clear on your side of the road; Gear appropriate for maximum vehicle control through the hazard, selected in one shift; and; Acceleration for clearing the hazard safely.
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 ...

In the United Kingdom, lights that changed to red when sensing that an approaching motorist was traveling too fast were being trialled in Swindon in 2011, [8] to see if they are more effective at reducing the number of accidents on the road than the speed cameras that preceded them and which were removed following a council decision in 2008 ...
