Vakionopeus, also known as cruise control, is a system in vehicles that automatically controls the engine speed to maintain a constant speed set by the driver. This allows the driver to relax their foot from the accelerator pedal for extended periods, particularly on long highway journeys. The system typically functions by monitoring the vehicle's actual speed and adjusting the throttle position accordingly to counteract any deviations from the set speed, such as those caused by inclines or declines.

Engaging vakionopeus is usually done via buttons on the steering wheel or dashboard. The driver sets the desired speed, and once engaged, the vehicle will attempt to maintain it. Most systems allow for adjustments to the set speed by simply pressing a "resume" or "accelerate" button, or by temporarily disengaging the system with a "cancel" button or by pressing the brake or clutch pedal.

While vakionopeus can enhance driving comfort and potentially improve fuel efficiency by maintaining a steady speed, it is important to use it judiciously. It is generally not recommended for use in heavy traffic, slippery conditions, or on winding roads where frequent speed adjustments are necessary. Modern vehicles may also feature adaptive cruise control, which goes a step further by automatically adjusting the vehicle's speed to maintain a safe distance from the vehicle ahead.
