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.
Other problems may be implicated in the case of older vehicles equipped with carburetors. Weak, disconnected, or mis-connected throttle return springs, worn shot-pump barrels, chafed cable housings, and cables which jump their tracks in the throttle-body crank can all cause similar acceleration problems.
The Dutch Connect&Drive project implemented CACC in seven Toyota Prius vehicles in 2009–2010. This project used a communication stack based on the reference architecture of the Car-2-Car Communication Consortium, using IEEE 802.11a hardware at the physical layer.
Adaptive cruise control does not provide full autonomy: the system only provides some help to the driver, but does not drive the car by itself. [3] For example, the driver is able to set the cruise control to 55mph, if the car while traveling that speed catches up to another vehicle going only 45mph, the ACC will cause the car to automatically brake and maintain a safe distance behind the ...
Some vehicles combine adaptive cruise control with lane keeping systems to provide additional safety. While the combination of these features creates a semi-autonomous vehicle [non sequitur], most require the driver to remain in control of the vehicle while it is in use. This is because of the limitations associated with the lane-keeping feature.
Cruise control buttons can adjust the speed on some vehicles. [2] Applying pressure to the accelerator or brake pedal will override the HDC system. Later implementations combine HDC with traction control and low-range gears and have reduced the set speed to slower than walking pace for extra control.
A control loop is the fundamental building block of control systems in general and industrial control systems in particular. It consists of the process sensor, the controller function, and the final control element (FCE) which controls the process necessary to automatically adjust the value of a measured process variable (PV) to equal the value of a desired set-point (SP).
