Definition and Mechanism of VDC in a Car – The letters VDC seem confusing to most people who are probably driving their first car. However, it actually makes sense in the world of motorized vehicles and is familiar with these letters.
Definition and Mechanism of VDC in a Car
What does VDC stand for? Well, the meaning of VDC is Vehicle Dynamic Control. VDC is a unique system for correcting steering problems in cars originating from several car manufacturer brands. Because it has the potential to save the lives of drivers and passengers of course, this stability control system is part of the vehicle’s dynamic control. Then, what does VDC in the car mean?
What exactly is VDC?
We will try to explore more about what these letters actually mean. VDC is another name for the electronic stability control (ESC) system on the Nissan, Subaru, and Infiniti models. VDC will work when there is understeer and oversteer and prevent these steering problems by lowering the speed and applying brakes to the wheels that are causing the problem. Since 2012, vehicles sold in the United States must have an ESC or VDC.
The VDC system monitors the wheel movement throughout the vehicle’s travel time. Therefore, the system can detect wheel slip marks before the driver detects any symptoms. VDC instantly applies countermeasures to combat loss of steering and traction control. This work system is an ongoing process and the driver does not know all the actions that are taking place.
This system helps keep the car on the road. However, this is not an alternative to the correct way of driving. This system might help in certain situations but if you are not careful it is still possible to lose control while driving. Even if the system remains active, VDC may be ineffective in cases of sudden throttle and steering applications.
You should always activate the system to ensure better driving safety. However, it needs to be disabled in some situations, such as freeing a car stuck in mud or snow.
What Does VDC in Car Mean?
The dynamic control system of Nissan cars means that your vehicle can fix steering errors and oversteering problems in most car conditions. This is similar to the traction control system used on vehicles of other car manufacturers. So, what does Vdc off mean? When the VDC OFF indicator light on the dashboard lights up, it indicates that the VDC system is not in use.
With the VDC system active, driving in bad weather conditions becomes more challenging. You can lose control while driving in the rain or on snowy roads if the VDC system is off. It is very common for car wheels to slip when the road is slippery due to water or ice. To avoid such accidents, you need to hit the brakes and slow down in a matter of seconds and this is difficult for humans in general. VDC systems truly save lives by stepping into the situation and taking the necessary action in seconds.
What does VDC in the car mean?
This means that the driver can have more control over the handling of the vehicle. The system assists in this by supplying the necessary power to the wheels to keep them on their proper course.
You should leave this system ON at all times, except for situations when the car is stuck due to snow or mud. In such cases, turning off the system will help you move the car to a safe place.
Nissan VDC is turned on when you start the car. If you cannot turn on the system or the VDC OFF indicator light is on, you need to press the VDC button manually to turn on the system. Shutting down the engine and then turning it back on can also serve to restore the VDC system.
System Mechanism VDC
Learning the VDC mechanism will help you understand the system better.
To understand the VDC mechanism, keep in mind that it is always active when you are driving a vehicle. This system continuously checks the direction and steering of the vehicle. By analyzing the steering wheel angle, VDC predicts the possible direction of the driver and compares it to the direction of the actual vehicle.
Under normal conditions, the two directions will be the same. However, the two will differ in the case of traction loss or wheel slip. It calculates the gap between the actual and desired direction and takes the necessary action to fix this problem.
When the system applies the brakes, it does this to each wheel to correct oversteer or understeer of the other wheels. For example, when the car experiences understeer, it does not respond to steering wheel rotation. If so, it forces the vehicle to turn by applying the brakes to the outside front wheels.
