Understanding Aftermarket Cruise Control Systems: How They Work, Benefits, and Considerations

Aftermarket cruise control systems provide a convenient and comfortable driving experience, allowing drivers to maintain a set speed without needing to keep their foot on the accelerator. This article delves into how these systems work, their components, and the benefits they offer. Additionally, it will discuss considerations for installation and compatibility.

Components of Aftermarket Cruise Control

Aftermarket cruise control systems are composed of several key components that work together to provide a seamless driving experience. Understanding the roles of each component is essential for anyone considering installing a cruise control system.

1. Control Module

The control module serves as the brain of the system. Its primary function is to process inputs and control the throttle. It receives data from sensors and adjusts the throttle accordingly to maintain the desired speed.

2. Throttle Actuator

The throttle actuator is a device that adjusts the throttle position to maintain the desired speed. It is often linked to the throttle cable or electronic throttle body, ensuring precise control over the engine's power output.

3. Speed Sensor

The speed sensor plays a vital role in monitoring the vehicle's speed. It continuously sends information to the control module, which then adjusts the throttle actuator based on the speed data.

4. User Controls

User controls are typically mounted on the steering wheel or a stalk, allowing the driver to set, adjust, and cancel the cruise control. These controls provide easy access for the driver to manage the system while driving.

How It Works

The functionality of an aftermarket cruise control system can be divided into several key steps:

Installation

Installation involves connecting the control module to the vehicle’s throttle and electrical systems. This often requires wiring the control module to the vehicle’s power supply and connecting the throttle actuator to the throttle cable or electronic throttle body. Professional installation is often recommended to ensure safe and reliable operation.

Activation

To activate the system, the driver simply accelerates to the desired speed and sets the cruise control using the user controls. Once set, the cruise control maintains the selected speed.

Speed Maintenance

The speed sensor continuously monitors the vehicle's speed. When the vehicle speed drops below the set speed, such as when going uphill, the control module signals the throttle actuator to open the throttle more to increase speed. Conversely, if the speed exceeds the set speed, the actuator reduces throttle input to maintain the desired speed.

Adjustment and Cancellation

Drivers can adjust the set speed using the user controls or cancel the cruise control at any time by pressing the brake pedal or using a designated cancel button.

Types of Aftermarket Cruise Control

Aftermarket cruise control systems can be categorized into two main types: mechanical systems and electronic systems.

1. Mechanical Systems

These systems use cables and levers to control the throttle. While they can be effective, they may require more maintenance due to wear and tear on the mechanical components.

2. Electronic Systems

Electronic systems interface directly with the vehicle’s electronic throttle control, providing more precise speed management. They are generally more reliable and easier to install, though the system’s compatibility with the vehicle is still a critical factor.

Considerations for Aftermarket Cruise Control Installation

Before installing an aftermarket cruise control system, there are several important considerations:

Compatibility

Compatibility is crucial. Not all vehicles are suitable for aftermarket cruise control systems. It is essential to check the compatibility of the chosen system with your vehicle before installation.

Installation

Proper installation is critical for safety and functionality. It often requires professional installation to ensure the system is set up correctly and safely.

Legal and Safety Regulations

Some jurisdictions may have regulations regarding aftermarket modifications. It is important to research local laws to ensure compliance.

Benefits of Aftermarket Cruise Control

Aftermarket cruise control systems offer several benefits, including:

1. Increased Comfort during Long Drives

By maintaining a steady speed, cruise control helps reduce driver fatigue, making long drives more comfortable.

2. Improved Fuel Efficiency

Maintaining a steady speed can improve fuel efficiency, as abrupt changes in speed can lead to increased fuel consumption.

Conclusion: Aftermarket cruise control systems enhance the driving experience and provide numerous benefits. Understanding the components and how they work, along with considering installation and compatibility, can help drivers make informed decisions when choosing a system.
