1. History of Cruise Control in 18 Wheelers

Early developments in cruise control technology

The first attempts at developing cruise control technology date back to the early 1900s. In 1902, the French inventor Alfred Amiot patented a cruise control system that used a centrifugal governor to maintain a constant speed. However, this system was not practical for use in 18 wheelers, as it was too sensitive to changes in road conditions.

In the 1930s, several other inventors developed cruise control systems, but none of these systems were able to overcome the challenges of road conditions and engine power. It wasn’t until the 1950s that a practical cruise control system was developed for 18 wheelers.

The first cruise control systems for 18 wheelers

The first cruise control system for 18 wheelers was developed by the Bendix Corporation in 1958. This system used a vacuum servo to maintain a constant speed. The driver set the desired speed, and the system would use the vacuum servo to apply the brakes or the accelerator to keep the truck at that speed.

The Bendix cruise control system was a major improvement over previous systems, but it still had some limitations. It was only available on trucks with a manual transmission, and it could be difficult to use in hilly terrain.

The evolution of cruise control systems for 18 wheelers

In the 1960s, several other companies developed cruise control systems for 18 wheelers. These systems used a variety of technologies, including hydraulic servos, electric motors, and electronic controls.

By the 1970s, cruise control systems had become a standard feature on most new 18 wheelers. These systems were more reliable and easier to use than earlier systems, and they helped to improve fuel economy and driver comfort.

In the 1980s, electronic cruise control systems became the standard. These systems were more precise and offered a wider range of features than earlier systems. They also allowed drivers to set the desired speed in miles per hour or kilometers per hour.

Today, cruise control systems are an essential safety feature on 18 wheelers. They help to reduce driver fatigue and prevent accidents.

2. How Cruise Control Works in 18 Wheelers

The basic principles of cruise control

Cruise control systems use a variety of sensors to monitor the speed of the truck and the road conditions. These sensors include a speedometer, a throttle position sensor, and a wheel speed sensor.

The cruise control system uses the information from these sensors to calculate the desired speed. It then uses an actuator, such as a vacuum servo or an electric motor, to apply the brakes or the accelerator to keep the truck at that speed.

The different types of cruise control systems for 18 wheelers

There are two main types of cruise control systems for 18 wheelers:

  • Speed-sensitive cruise control systems maintain a constant speed regardless of the road conditions.
  • Adaptive cruise control systems adjust the speed of the truck to maintain a safe distance from the vehicle in front of it.

Speed-sensitive cruise control systems are the most common type of cruise control system for 18 wheelers. They are relatively simple and inexpensive to install.

Adaptive cruise control systems are more advanced than speed-sensitive cruise control systems. They use radar or laser sensors to monitor the distance between the truck and the vehicle in front of it. They can then adjust the speed of the truck to maintain a safe distance.

How to use cruise control in an 18 wheeler

To use cruise control in an 18 wheeler, follow these steps:

1. Set the desired speed using the cruise control control stalk.
2. Press the set button to engage the cruise control system.
3. The cruise control system will maintain the desired speed until you press the cancel button.

You can also use the cruise control system to accelerate or decelerate the truck. To accelerate, press the accelerator pedal. To decelerate, press the brake pedal.

If you need to turn off the cruise control system, press the cancel button.

Cruise control systems are an essential safety feature on 18 wheelers. They help to reduce driver fatigue and prevent accidents. By understanding how cruise control works, you can use it safely and effectively to improve your driving experience.
