What Is Adaptive Cruise Control? Feature Explained

What Is Adaptive Cruise Control?

Adaptive Cruise Control (ACC) automates speed adjustments to maintain a safe following distance from the car ahead. Here’s how it works:

• Set Your Speed: Choose your desired cruising speed using cruise control buttons.
• Sensor Detection: Radar or camera sensors monitor the distance to the vehicle ahead.
• Automatic Speed Adjustment: ACC reduces your speed if the car ahead slows down and resumes your set speed once a safe distance is re-established.

How Does Adaptive Cruise Control Work?

ACC uses sensors positioned at the front of your car:

• Radar: Emits radio waves to calculate the distance to the vehicle ahead, effective in most weather conditions.
• Camera: Captures real-time footage to identify the leading vehicle, though less effective in low-light or dusty conditions.

The data is processed by the car’s ECU, which takes the following actions:

• Maintain Speed: If the road is clear, ACC keeps your set cruising speed.
• Slow Down: Reduces power or applies brakes to maintain a safe distance.
• Resume Speed: Increases power or disengages brakes once a safe distance is restored.

What Are the Pros & Cons of Adaptive Cruise Control?

The pos or advantages of adaptive cruise control in a car are:

• Reduced Driver Fatigue: Long highway drives can be exhausting. ACC manages your cruising speed, reducing the need for constant pedal adjustments and promoting relaxation.
• Improved Safety: By maintaining a safe distance, ACC helps prevent rear-end collisions, particularly in stop-and-go traffic.
• Enhanced Comfort: ACC provides a smoother driving experience, ideal for long journeys.

The cons or disadvantages of adaptive cruise control are:

• Challenges on Indian Roads: ACC might struggle with sudden lane changes, erratic driving, and large vehicles like trucks or tractors. Drivers must stay alert and ready to take manual control.
• System Dependence: Overreliance on ACC can lead to complacency. Always remain attentive to road conditions.
• Cost Factor: Vehicles equipped with ACC are generally more expensive.

Is Aftermarket Installation Of Adaptive Cruise Control Possible?

Aftermarket installation of ACC is technically possible, but it comes with challenges:

• Compatibility: Not all vehicles are designed to support aftermarket ACC systems, requiring significant modifications.
• Cost: Installing ACC can be expensive, often costing as much as factory-installed systems.
• Reliability: Aftermarket systems may lack the precision and integration of factory-installed systems, impacting performance.
• Warranty Issues: Modifications may void your vehicle’s warranty, so consult your manufacturer before proceeding.

Cars With Adaptive Cruise Control in India

ACC is increasingly available in India, featured in models like the Honda City, Honda Elevate Hyundai Verna, MG Astor, Mahindra XUV700, and Tata Safari. 

Cost Of Repairing Adaptive Cruise Control

ACC systems are complex and require delicate calibration. Repair costs can be high, depending on the level of damage. Hence, we recommend you consult your authorised service centers for a repair estimate.
