Does cruise control keep a speed?
Cruise control (sometimes known as speed control or autocruise, or tempomat in some countries) is a system that automatically controls the speed of a motor vehicle. The system is a servomechanism that takes over the throttle of the car to maintain a steady speed as set by the driver.
What’s the best speed to drive with cruise control?
According to the Department for Transport, driving at a steady speed of 50 mph instead of 70 mph can improve fuel economy by 25%. Additionally, setting your cruise control to the speed limit can help you avoid speeding fines. It can be especially helpful in today’s driving climate as average-speed cameras are becoming increasingly common.
What happens when your cruise control goes to 70?
The kids in the back seat have stopped threatening to throw up, too. Then you look in your mirror 20 miles later and see the lights. Red and blue flashing lights. You’re doing over 85 mph and, odds are, Smokey isn’t going to believe you have the cruise set to 70. Time to find out why your cruise control has a mind of its own.
How does cruise control work in a car?
The cruise control feature works to maintain the vehicle at a constant speed without the need to step on the accelerator pedal. Once activated, the cruise control system will keep the vehicle at a constant speed or rate of acceleration until it is switched off manually or the brake pedal is stepped on.
How do you cruise at a higher speed?
To cruise at a higher speed after cruise control has been engaged, the driver accelerates to the higher speed and then fully depresses and slowly releases the control switch button. To cruise at a lower speed, fully depress the control switch button and hold it until the vehicle has decelerated to the desired lower speed.

How does a cruise control system work on a truck?
Some older systems, used on cars or trucks that don’t have throttle-position sensors, may have a rod that moves in and out of a magnetic coil to tell the controller the throttle position. There are also two electrically operated solenoid valves. One valve admits vacuum to the diaphragm chamber to add more throttle.
Is it dangerous to use cruise control in rain?
Dear Bob: Cruise control can be dangerous. I have experienced, when driving in heavy rain or slush conditions with the cruise control set at a speed of around 70 mph, that one front wheel will hydroplane while the other wheel suddenly gets traction. Result: The car spins out and into the ditch or into traffic.
Is it too late to disengage cruise control?
An activated cruise control system applies continuous power, keeping the wheels spinning. By the time you disengage the cruise control it may be too late – you may have already lost control. An example from the weekly “Drive It Forever” automotive column by New York Times Syndicate writer Bob Sikorsky provided a description of one such occurrence:
