The system is a servomechanism that takes over the throttle of the car to maintain a steady speed as set by the driver. HistoryeditSpeed control was used in automobiles as early as 1. Wilson Pilcher and also in the 1. Peerless. Peerless advertised that their system would maintain speed whether up hill or down. The technology was adopted by James Watt and Matthew Boulton in 1. On an engine the governor adjusts the throttle position as the speed of the engine changes with different loads, so as to maintain a near constant speed. Modern cruise control also known as a speedostat or tempomat was invented in 1. Ralph Teetor. 1 His idea was born out of the frustration of riding in a car driven by his lawyer, who kept speeding up and slowing down as he talked. The first car with Teetors system was the 1. Agricultural Exchange Programs : Free Programs, Utilities And Apps. Imperial called Auto pilot using a speed dial on the dashboard. This system calculated ground speed based on driveshaft rotations off the rotating speedometer cable, and used a bi directional screw drive electric motor to vary throttle position as needed. A 1. 95. 5 U. S. Patent for a Constant Speed Regulator was filed in 1. M Sgt Frank J. Riley. He installed his invention, which he conceived while driving on the Pennsylvania Turnpike, on his own car in 1. Despite this patent, the inventor, Riley, and the subsequent patent holders were not able to collect royalties for any of the inventions using cruise control. In 1. 96. 5, American Motors AMC introduced a low priced automatic speed control for its large sized cars with automatic transmissions. The AMC Cruise Command unit was engaged by a push button once the desired speed was reached and then the throttle position was adjusted by a vacuum control directly from the speedometer cable rather than a separate dial on the dashboard. Daniel Aaron Wisner invented Automotive Electronic Cruise Control in 1. RCAs Industrial and Automation Systems Division in Plymouth, Michigan. His invention described in two patents filed that year US 3. US 3. 51. 13. 29, with the second modifying his original design by debuting digital memory, was the first electronic device in controlling a car.

This Speed Sensor was designed in the USA specifically for the WarP series of motors with a tailshaft diameter of. Zolox. The advantage of electronic speed control over its mechanical predecessor was that it could be integrated with electronic accident avoidance and engine management systems. Following the 1. 97. U. S. 8 Cruise control can save gas by avoiding surges that expel fuel while driving at steady speeds. In 1. AMC, GM, and Chrysler priced the option at 6. Ford charged 1. 03. OperationeditThe driver must bring the vehicle up to speed manually 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 engines RPM, or from internal speed pulses produced electronically by the vehicle. Most systems do not allow the use of the cruise control below a certain speed typically around 2. The vehicle will maintain the desired speed by pulling the throttle cable with a solenoid, a vacuum driven servomechanism, or by using the electronic systems built into the vehicle fully electronic if it uses a drive by wire system. All cruise control systems must be capable of being turned off both explicitly and automatically when the driver depresses the brake, and often also the clutch. Cruise control often includes a memory feature to resume the set speed after braking, and a coast feature to reduce the set speed without braking. When the cruise control is engaged, the throttle can still be used to accelerate the car, but once the pedal is released the car will then slow down until it reaches the previously set speed. On the latest vehicles fitted with electronic throttle control, cruise control can be easily integrated into the vehicles engine management system. Modern adaptive systems see below include the ability to automatically reduce speed when the distance to a car in front, or the speed limit, decreases. This is an advantage for those driving in unfamiliar areas. The cruise control systems of some vehicles incorporate a speed limiter function, which will not allow the vehicle to accelerate beyond a pre set maximum this can usually be overridden by fully depressing the accelerator pedal. Most systems will prevent the vehicle accelerating beyond the chosen speed, but will not apply the brakes in the event of overspeeding downhill. On vehicles with a manual transmission, cruise control is less flexible because the act of depressing the clutch pedal and shifting gears usually disengages the cruise control. The resume feature has to be used each time after selecting the new gear and releasing the clutch. Therefore, cruise control is of most benefit at motorwayhighway speeds when top gear is used virtually all the time. Advantages and disadvantageseditSome advantages of cruise control include Its usefulness for long drives reducing driver fatigue, improving comfort by allowing positioning changes more safely across highways and sparsely populated roads. Some drivers use it to avoid subconsciously violating speed limits. A driver who otherwise tends to subconsciously increase speed over the course of a highway journey may avoid speeding. However, when used incorrectly cruise control can lead to accidents due to several factors, such as speeding around curves that require slowing downrough or loose terrain that could negatively affect the cruise control controlsrainy or wet weather could lose traction. Adaptive cruise controleditSome modern vehicles have systems for adaptive cruise control ACC, which is a general term meaning improved cruise control. These improvements can be automatic braking or dynamic set speed type controls. Automatic Braking Type the automatic braking type use either a single or combination of sensors radar, lidar,and camera to allow the vehicle to keep pace with the car it is following, slow when closing in on the vehicle in front and accelerating again to the preset speed when traffic allows. Some systems also feature forward collision warning systems, which warn the driver if a vehicle in frontgiven the speed of both vehiclesgets too close within the preset headway or braking distance. Dynamic Set Speed Type The dynamic set speed uses the GPS position of speed limit signs, from a database. Some are modifiable by the driver. At least one, Wikispeedia, incorporates crowdsourcing, so driver input is shared, improving the database for all users. Non Braking Type The speed can be adjusted to allow traffic calming. One visual method uses Open. CV1. 0Vehicles with adaptive cruise control are considered a Level 1autonomous car, as defined by SAE International.
