Cruise control is an electronic device within your vehicle that controls the speed of your vehicle. It allows the driver to maintain a constant speed of 25 mph without holding their foot on the accelerator. Although the feature has been around for 70 years, automotive manufacturers continue to improve upon the technology to provide drivers with increased comfort, luxury, and convenience whenever they’re behind the wheel.
Adaptive cruise control
This time it was using all the modern techniques like various sensors and electronic actuators. It began as the first safety operating system using only stereo cameras. In the last twenty years, EyeSight has evolved to include adaptive cruise control, lane keep assist and sway warning, pre-collision braking, and pre-collision throttle management.

These systems are being enhanced to include collision warning capabilities that will warn drivers through visual and/or audio signals that a collision is imminent and that braking or evasive steering is needed. In 1958, Chrysler was first to offer Speedostat as a luxury model option. A year later, its popularity influenced Chrysler to offer Speedostat on all car models.

His solution would count the rotations of the vehicle’s drive shaft to calculate its speed, then use a bi-directional screw-drive electric motor to adjust the throttle and maintain an even pace. With a reputation for safety in a world of rapidly growing technology, safety tech on cars is part of the natural progression. When EyeSight was introduced that year it set a new precedent in vehicle technology geared toward safety. It began a wave of innovation that made similar safety systems show up in vehicles across the board. Laser-based systems do not detect and track vehicles in adverse weather conditions nor do they reliably track dirty (and therefore non-reflective) vehicles. Laser-based sensors must be exposed, the sensor (a fairly large black box) is typically found in the lower grille, offset to one side.
What we’d consider modern cruise control came about in the late 1940s, invented by a man named Ralph Teetor. Teetor, who was completely blind, was one of the foremost automotive engineers of his generation. His invention, first called ‘Speedostat’, was introduced in a Chrysler car as a luxury option. Its surge in popularity led the brand to install a ‘Speedostat’ it in all its vehicles.

A good cruise control system accelerates aggressively to the desired speed without overshooting, and then maintains that speed with little deviation no matter how much weight is in the car, or how steep the hill you drive up. Controlling the speed of a car is a classic application of control system theory. The cruise control system controls the speed of the car by adjusting the throttle position, so it needs sensors to tell it the speed and throttle position. It also needs to monitor the controls so it can tell what the desired speed is and when to disengage. The cruise control system actually has a lot of functions other than controlling the speed of your car.

Modern systems are electronic, utilizing sensors, actuators, and computer control to maintain a set speed. But the real impact of cruise control might be that it surfaced the tip of the iceberg for Advanced Driver Assistance Systems and, eventually, autonomous driving. In some cars, the system will cruise at the current speed, in others it might need to be set. To deactivate the system, the driver must simply press the brake or clutch pedal or cancel it using a button that usually found on the steering wheel. Modern cruise control systems began to emerge in the 1990s, with manufacturers incorporating more advanced digital technology into the design. Other systems such as LiDAR, radar, sonar and camera-based solutions were soon added, increasing the car’s ability to sense oncoming traffic, which in turn helped the vehicle to determine speed and avoid potential accidents.

Then, when the road is clear, the system will re-accelerate the vehicle back to the set speed. Cruise control takes over the throttle of a vehicle to maintain a steady speed that the driver sets. Cruise control adjusts a car’s speed by adjusting the throttle position. But it does this by actuating the throttle valve by a cable connected to an actuator rather than pressing a pedal. Drivers can set the cruise control with switches typically marked as ON, OFF, RESUME, SET, ACCEL, and COAST.

Starting with automatic transmission to cruise control everything is making the driving experience lethargic but super easy. In the abundance of convenience features, today let’s have a look at the ‘cruise control’ and where it all started. While cruise control dates to 1788 when an early version was used in steam ships, modern cruise control was invented in 1948. In 1965, the first car with cruise control was introduced to the market by American Motors. Eight years later, during the 1973 oil crisis, cruise control gained popularity because it was advertised as a way to save gas.
When it comes to safety surely the automotive sector is now safer than ever. But talking about driving, in the 21st century automated everything is the new cool. The specified fuel consumption and emission data have been determined according to the Worldwide Harmonized Light Vehicles Test Procedure (WLTP). When figures are specified as value ranges, these do not refer to a particular individual vehicle, but to different trims. A governor was used by James Watt and Matthew Boulton in 1788 to control steam engines, but the use of governors dates at least back to the 17th century.
Cruise controls is usually packaged as part of the vehicle’s advanced driver-assistance system (ADAS). ADAS, while not autonomous, is constantly evolving to bring drivers new and more powerful safety features. However, Level 2 ADAS systems are viewed by some as the next step towards autonomous vehicles, with technology such as adaptive cruise control playing a core role in their argument. The problem with this though, is that partial automation (AKA cruise control) in cars has led some drivers to grow confused as to how far their vehicle’s autonomy extends, which is a dangerous combination. Recently, Tesla ran into trouble with its customers regarding complaints over cruise control deteriorating over time. The ‘phantom-breaking’ drivers experienced, where the EV would break suddenly and without warning, would almost cause the cars to be rear-ended.
As you’re learning how to operate a vehicle, understanding cruise control will help increase your comfort behind the wheel and knowledge of driving. Cruise control is most effective on highways with consistent traffic flow. It may not be suitable for congested city driving or on winding roads where frequent speed adjustments are required. Modern cruise control began to emerge in the 1990s, with advanced digital technology incorporated into the design. Here in India, most of the cars come with a conventional cruise control system. Well, we are talking about cars excluding the high-end ones (Audis, BMWs, Mercedes-Benz and more).
The throttle valve controls the power and speed of the engine by limiting how much air the engine takes in (see How Fuel Injection Systems Work for more details). While cruise control can enhance comfort and fuel efficiency, drivers should remain attentive and be ready to take control at all times. It’s not recommended for use in heavy traffic or adverse weather conditions. Mapping data has further enhanced cruise control by allowing cars to make smarter decisions on the road. For instance, HERE’s own mapping data allows adaptive cruise control to anticipate the speed, curvature, and slope of the road ahead, and improves fuel efficiency in vehicles with predictive cruise control. Already experienced with vehicle mechanisms, having been a pioneer of automatic transmission, Teetor set about designing a solution to his lawyer’s pesky driving habits.
However, they will not apply the brakes in the event of overspeeding downhill, nor stop the car from going faster than the selected speed even with the engine just idling. In addition, it had an upgraded all-speed range adaptive cruise control system. EyeSight was now able to stop the car if the vehicle in front slowed down or stopped unexpectedly. These new features would not only add to the list of existing safety assistance, but also lower the risks usually considered in context with certain driving circumstances such as slow or high-volume traffic situations. As for adaptive cruise control, the first company to bring it to market was Mercedes-Benz. Both systems allow a driver to set a speed and distance they want between their vehicle and the one in front of it.
A shop accident at the age of five took Teetor’s sight away, but he quickly learned how to develop his other senses and tap into his passion for mechanics. In fact, his increased abilities to hear and sensitivity to touch made him better able to diagnose and fix mechanical problems. 1900, the time when the automotive industry was in hot books and saw a new invention or implementation almost every day. Hyundai is announcing that the Insurance Institute of Highway Safety has honored a total of 16 models from Hyundai Motor Company, Kia Corporation, and Genesis.
