Vakionopeudensäätimet, or cruise control systems, are devices that automatically maintain a vehicle's speed set by the driver. These systems are designed to reduce driver fatigue during long journeys by eliminating the need to constantly adjust the accelerator pedal. A typical cruise control system utilizes a sensor to monitor the vehicle's speed. When the driver sets a desired speed, the system engages a controller that adjusts the engine's throttle to maintain that speed, even when encountering inclines or declines. The system can be disengaged by the driver through braking, accelerating, or a dedicated cancel button.

Modern vehicles often feature adaptive cruise control (ACC). ACC systems go beyond simply maintaining a set speed. They use radar or lidar sensors to detect the distance and relative speed of vehicles ahead. If the ACC system detects a slower vehicle, it will automatically reduce the vehicle's speed to maintain a safe following distance. Once the obstruction is cleared, the ACC system will accelerate the vehicle back to the preset speed. This advanced functionality further enhances driver comfort and safety. The development of cruise control has significantly impacted long-distance driving experience, contributing to fuel efficiency and driver well-being.
