What is Cruise Control?
Cruise control is a smart driving device which allows your vehicle to operate at a constant rate without the need to press your accelerator. It is automatic and adjusts the throttle based on the speed you set. It is especially useful when you’re on a highway or on an open road that has no traffic issues.
The primary goals of cruise control are to make the long-distance travel experience less tiring and to increase fuel efficiency. The systems are available with various levels of automation and precision, and different models are available depending on the model of car.
Furthermore, these cruise controls in use today aren’t just cables and are reliant on sophisticated sensors connected with an Electronic Control Unit (ECU). If drivers make an option regarding the speed, the ECU will detect the input, then electronically adjust the throttle to make the vehicle operate at the appropriate speed.
If the road conditions are different, it adjusts the throttle to keep the same speed, resulting in an easier and more relaxing cruise.
How to Use Cruise Control?
Cruise control is an extremely useful feature to include in your car as it helps keep a steady pace without using your accelerator. When you press an appropriate velocity, the throttle will be auto-controlled by the program to keep the vehicle’s speed at the same pace. In simplest terms, it will take over the function of your accelerator pedal and adjust the engine’s power in order to maintain the speed you have set.
This makes long drives more comfortable and helps improve fuel efficiency. The steps to use cruise control are as follows:
Step 1: Set Your Cruise Speed
Start driving and accelerate to the desired speed. Click on “SET” in your car’s cruise control system, and the current speed will be locked in.
Step 2: Relax Your Foot
Once the speed is adjusted, take your foot off the accelerator. The throttle will be automatically controlled so that the car maintains the same speed, and you can have a more comfortable ride.
Step 3: Pause or Resume While Cruising
If you need to slow down suddenly or stop, simply press the brake pedal. The cruise control will temporarily disengage. To resume the previous speed, press the “RES” or “Resume” button.
Step 4: Manual Override
You can resume full manual control of your car by either the accelerator or the clutch. Cruise control may also be switched off by the “CAN” or “Cancel” button. Lastly, use the “OFF” button to switch off the system.
Step 5: Adjust Speed
Want to modify your cruising speed? Use the “+” button to accelerate or the “-” button to decelerate while in cruise mode. In some vehicles, you can adjust your speed manually and then press “SET” again to save the new speed.
By following these tips, you can optimise the use of your car’s cruise control technology in order to have a more relaxed, safer and enjoyable ride.
Advantages of Cruise Control in a Car
Cruise control in cars transforms long trips on highways by enhancing comfort, safety and efficiency. Here’s how:
- Reduced Driver Fatigue
When travelling long distances, driver fatigue can be a major issue. After activating cruise control, the driver does not have to keep pressing the accelerator pedal, which enables them to rest and focus fully on the road ahead.
- Improved Fuel Efficiency
Cruise control maintains a consistent speed, and thus it prevents unwarranted acceleration and deceleration. This helps provide maximum fuel efficiency because cars use more fuel when they frequently change speed.
In the case of long-distance travel, this feature could result in a reduction in fuel costs, making your trip more efficient and environmentally friendly.
- Increased Safety
An adaptive cruise control system found in modern cars is a security improvement, as it regulates the speed, ensuring an adequate distance between the vehicle and the other car. The system reduces the risk of rear-end collisions as well as accidents resulting from abrupt braking or improper driving control, thereby making the driving experience secure and enjoyable.
- Better Speed Regulation
By using cruise control, drivers have a lower chance of accidentally overspeeding. The system ensures that the vehicle is at a pre-set, constant speed. This will not only help avoid speeding but also encourage safer and more prudent driving habits.
- Enhanced Comfort
If you are on a long road trip or highway, cruise control helps you rest by ensuring a certain speed. This allows for better comfort for passengers.
Disadvantages of Cruise Control in a Car
Although cruise control is a convenient option, its use in India is limited by different driving conditions. These include:
- Limitations in India
Cruise control is most efficient when used on straight highways having disciplined drivers and regular traffic patterns. Yet, Indian roads often present the reverse scenario. Despite being well-constructed, expressways’ irregular lane control, sudden lane changes and unpredictable driving habits make it difficult to trust cruise control.
Moreover, stray animals like dogs and cows or unexpected pedestrians may suddenly appear, forcing drivers to shut off the system. This makes it difficult to operate cruise control for a prolonged time in India’s highly rapidly changing driving surroundings.
- Increased Reaction Time
On Indian roads, accidents can be avoided by braking quickly, particularly in emergencies. When driving in manual mode, the driver’s feet are in the middle of the brake and accelerator pedals, allowing an immediate reaction.
When cruise control is turned on, the driver’s right leg generally rests on the ground, and it takes longer to transfer it to the brake lever. Just a tiny fraction of a second delay in these scenarios could be the difference between avoiding a collision and causing an accident.
- Induces Drowsiness
Drivers are less alert due to prolonged driving hours with cruise control. The car is at a speed that reduces the driver’s involvement, which can cause drowsiness at times. This can result in major accidents, particularly on crowded roads. To prevent this, drivers should shift to manual control every 15 to 20 minutes to ensure they are fully alert to the road conditions.
- Limited Usefulness at Night
Cruise control isn’t feasible during nighttime driving due to low visibility. This is because the capability of drivers to recognise dangers at an extended distance is reduced at night, as compared to daytime. It can also lead to the fear of handing over the control of the vehicle’s speed to an automated system.
- Less Enjoyable with Manual Transmission
For vehicles that have a manual transmission, it is possible to experience cruise control in a restricted manner. While the system can control both acceleration and deceleration, drivers have to manually shift gears to ensure optimal engine performance.
A constant change of gears with different speeds could make the process tedious and interfere with the smooth operation of cruise control. While this isn’t a major issue, it could affect the overall user experience and comfort.
What is Adaptive Cruise Control?
Adaptive Cruise Control (ACC) is an efficient and advanced method of controlling cruise systems. This differs from the conventional cruise control systems that don’t alter the speed of the car. On the contrary, ACC will automatically alter the speed of a moving car, based on the speed and distance of the car ahead.
It continuously scans the surroundings using sensors and radar to ensure a secure and comfortable following distance so that drivers don’t need to constantly apply their accelerators or brakes. This is especially beneficial for those who often travel for long distances because it reduces fatigue for drivers and provides a more comfortable, relaxed, stress-free driving experience.
Besides, the adaptive cruise control works truly well even in a traffic jam in the city. When there is heavy traffic or when the vehicle is moving slowly because of stop-and-go conditions, it automatically decelerates or accelerates accordingly, and the driver can remain calm and concentrated. Adaptive cruise control is one of the key features for a modern driver, as it can help make every journey much more comfortable and easy, with an increase in safety and comfort as well.
