Another example of open loop control systems is a vehicle driving on a road. In this case we’ll consider that the input is the engine torque, the system is the vehicle itself and the output is the vehicle speed. The driver is adjusting the engine torque (input) by pressing the accelerator pedal. Cruise control is a system in cars that automatically controls the speed of the car.
The Real Dangers Of Texting And Driving
The 2024 Hyundai Elantra and 2024 Toyota Corolla are old rivals in affordable compact cars. While wheel alignment and balance both contribute to a smoother ride, the services are quite different. A wheel alignment makes sure your tires contact the road in the correct way... Have you ever been confused as to the sounds coming from your vehicle when you brake? From grinding and rattling to thumping and squealing, you can learn how to decode...

Adaptive cruise control improves upon conventional cruise systems by not only maintaining a preset speed, but also by automatically keeping a safe distance between your car and the vehicle in front of it. Using forward-pointed sensors, cameras, or both, adaptive cruise control maintains your preset speed while constantly monitoring the vehicle in front of you. However, the kicker is, it automatically slows and accelerates to maintain a predetermined following distance. More sophisticated adaptive cruise control systems can bring your car to a full stop If necessary.
How Does The Cruise Control System In Cars Work?
The inventor and mechanical engineer James Watt developed a version as early as the 17th century, which allowed steam engines to maintain a constant speed up and down inclines. Cruise control as we know it today was invented in the late 1940s, when the idea of using an electrically-controlled device that could manipulate road speeds and adjust the throttle accordingly was conceived. Adaptive cruise control is a more advanced technology that enables you to set a specific speed while the system automatically reads the traffic ahead and keeps your car at a safe following distance.
For example, Audi's Traffic Jam Assist technology can be activated in tandem with its adaptive cruise control, thereby supporting the driver in conditions that aren't optimal for the latter. By means of ultrasonic sensors, radar, and a windshield camera, the vehicle will maintain a consistent distance from the one ahead in traffic while staying oriented on the road. The driver takes full manual controlwhen the congestion clears or Traffic Jam Assist otherwise becomes unsuitable for the situation. Two companies are developing a more advanced cruise control that can automatically adjust a car's speed to maintain a safe following distance.
Speedometer Vs GPS: Whose Speed Reading Is More Accurate?
The car’s engine and transmission work together to maintain that speed without any input from the driver. Cruise control is a feature provided as standard on a wide range of vehicles; it's one of those functions that some drivers adore and others barely use. While the feature doesn't take over from the driver by any means, it can significantly ease their burden.
Therefore, cruise control is most beneficial at motorway/highway speeds when top gear is used virtually all the time. The driver can set the cruise control with the cruise switches, which usually consist of ON, OFF, RESUME, SET/ACCEL and COAST. These are commonly located on the steering wheel or on the windshield wiper or turn signal stalk. Tapping the knob in the opposite direction will decelerate the vehicle.
To use cruise control safely, it’s best to know when you should and shouldn’t use it. [9] Using cruise control on the highway makes your driving more predictable to other drivers. Instead of constantly changing speeds, cars know how fast you’re driving and can follow safely behind you or pass.
Depending on the year, make and model, cruise control may be available for add-on or retrofit. Professional installation is recommended, and you’ll want to talk to a professional about the specific availability of parts and integration for your vehicle. Your vehicle’s engine, transmission and other components are designed to work hand-in-hand with its cruise control system and are extensively tested and integrated with one another for trouble-free performance. That’s been the case for the last decade or so, so there are loads of used cars with cruise control, as well.
For others, driving tends to be a commuter's cacophony of traffic jams, honking horns, and slow stop-start-stop-start progress. The experience can differ greatly depending on the time of day and whether it's a weekday or the weekend. The bottom line, though, is that one of these scenarios is a far better fit for cruise control than the other. A car with ACC will commonly boast small wheel-mounted units that measure its speed, along with a front-mounted one that can determine how far away other vehicles are. The former can adjust how fast your vehicle is moving relative to any motorists ahead, thereby ensuring that you always maintain your selected distance from them. Braking capacity while the system is active differs, but typically, the driver will be alerted to brake heavily if necessary (if a driver ahead does the same for instance).
Picture it like a synchronized dance on the highway, where every car knows its place and keeps the right distance. At its core, cruise control involves a series of sensors that monitor the vehicle's speed and a control unit that regulates the throttle. When the driver sets the cruise control to a specific speed, the system adjusts the throttle to maintain that speed.
