Cruise control is a crucial feature in many vehicles today. It allows drivers to set and maintain a constant speed without having to continuously press the accelerator pedal. This can be especially beneficial on long road trips or in heavy traffic. Cruise control can also help improve fuel efficiency by maintaining a steady speed.
One of the most important historical developments in cruise control was the invention of the electronic cruise control system in the 1950s. This system used a feedback loop to automatically adjust the throttle position in order to maintain a set speed. Electronic cruise control systems are now standard equipment on most vehicles.
