When it turned into twentieth-century various kinds of vehicles have been introduced to provide convenience in our daily life, thanks to the advanced technology and intelligent software developments, it now allows a car to drive faster and safer without many interventions of human. It, on the contrary, brings in some problems such as the happenings of accidents due to driver’s fatigue after a long journey of travel, the shortage of parking lots, difficult weather conditions or dark-time driving. With a large number of car accidents annually and so many dangers and financial problems along with it, so many auto-makers have been trying to develop and improve the quality of driving in order to improve safety when driving. The development of models to monitor driver’s behaviors have been proposed and brought in many promising results. From a study conducted by Mercedes Benz, it reports that if it can get an extra 0.5 seconds in the warning period it will avoid 60% of the overrun accidents and it will reach 90% if 1.5 seconds is added into the warning period.
Intelligent Night Vision System (INVS)
The driver’s visible range will be restricted when driving at night or bad weather, also the lighting range will be limited to restrain the driver from clearly noticing people moving along the roadside or the person is in repairing his out of condition car. The INVS will display the front road condition on the LCD screen of the car audio system by using infrared camera to control and determine the road condition to present to the driver a complete knowledge of the front road condition to greatly reduce the possible occurrences of accidents.
Lane Keeping Assist System (LKA)
The LKA camera will monitor the other vehicle directions and give a warning signal when the driver suddenly crosses the passing lane/ dividing lane or enters from opposite site, therefore giving timely attention for the driver to manage the driving directions in order to avoid collisions.
Adaptive Front-Lighting System (AFS)
With the use of high intensity discharge (HID), the AFS catches the moving direction of the car via the sensor that internally installed in control system. Therefore, enable drivers to determine obstructions and pedestrians along the way. The Xenon light helps to optimize the lighting range and extend the vision for drivers to clearly see the road when driving.
Low-Speed Following Mode (LSM) System
Whenever driver accelerates, decelerate or stop when driving, the LSM system will calculate the distance to the front car by the mini-meter wave radar, from there to keep the car driving in a safety distance. Also, it helps in maintain a safety speed by controlling the brake and from there help in reduce the waste fuels. If there is any problems from the front car or any obstacle on the street, the alarm system will exclaim to warn the driver.
Video Parking Assist System
With the rhythmic coordination among camera systems and collision avoidance radar, the images from front to backside will be shown clearly to help the driver to adjust the rotation and crab angles, the support linear system, therefore, assist the driver to complete the actions in stopping and parking. The wheel rotating mechanism now coordinate with the VPA system to automatically support the driver in reversing the car into the garage quicker and smarter. Also, It has other systems such as Adaptive Cruise Control (ACC), Electronic Stability Control (ESC), Emergency Brake Assist (EBA), Blind Spot Warning etc… each system has its own specific functions and will not discuss them further. In the design of the safety vehicle driving system, it needs to consider and include the following four processes:
- Normal condition – Provide the best visual guidance and reduce the burden in driving.
- Prior to accidence: provide warning actions and prevent accidents by diminishing the appearance of collisions.
- During the accidence – to reduce the damage and the collection of accident data and information.
- After accidence – provide emergency treatment and record the faulty errors.
Intelligent speed assist (ISA)
This system has developed for purpose of preventing exceed the speed limit when driving. This system can determine the car location via GPS, then access to the data source to determine the speed limit for each road and limit zone which the car is traveling in. The driver will be notified and announced directly about appropriate speed which can be used in the area they are driving. Also, when the driver wants to accelerate instantly, the system will pull up the pressure on the accelerator for making it difficult to increase the speed. This is not only help to remind the driver about their speed limit but also prevent the risks of excessive speeding. It expected to reduce the fatal crashes and accident rate up to 35% in the next few years.
Noise
The Kumho Ecsta PA31 is both comfortable and relatively quiet on the highway. I heard a bit more tire roar when the speedometer was approaching higher-than-average speeds, but it wasn’t enough to upset the calm nature of the car.
Treadwear
Perhaps the biggest selling point of the Kumho Road Venture AT51 is the price. You can buy a more expensive set of all-terrain tires from Bridgestone or Michelin and expect the tires to perform better than other cheaper alternatives. However, the Kumho Road Venture AT51 offers almost the same level of wet, dry, and snow performance while costing almost half as much. You also get an aggressive go-anywhere style, which will perfectly match the rugged nature of your truck or SUV. I am aware that style should take a backseat when choosing a brand new set of tires, but there’s nothing wrong with choosing a tire that looks the part as well.
Conclusion
This Kumho Ecsta PA31 review allowed me to spend some time driving a car that I would have previously overlooked. This tire should be included in your shopping list if you are the proud owner of a mid-level sedan or sports coupe.
