Currently, most new car models integrate many functions to help the driver avoid potential hazards, making driving safer. One of the smart safety features that many people appreciate is the DSC.
So what is DSC in a car? How useful is it? If you still don’t know the DSC car meaning, this post is for you. Please find out more details in the article below.
What Is DSC In A Car?
What does DSC stand for in a car? It stands for Dynamic Stability Control, a system that helps to mitigate engine torque and prevent loss of steering control.
The system has anti-lock ABS braking, dynamic suspension control, roll stability control, and corner brake control.
The operation of DSC is to monitor the individual wheels’ speed, combined with the steering wheel angle sensor, to have a timely processing direction.
When loss of traction occurs, the DSC will automatically control the anti-lock brake system to return it to equilibrium.
Depending on the wheel type, the DSC will optimally control the output in the anti-slip protection system.
Coming with that is the conventional traction control system and 4-wheel anti-lock braking system operating simultaneously.
For example, when the car starts to turn away from the bend, the inner wheel brake will automatically reduce the engine to prevent wheel slip.
Conversely, when the vehicle is entering a curve or speeding, DSC will initiate the function by reducing the engine in the outer wheel. This helps to ensure the safety of the operator throughout the journey.
How Does DSC Work?
The Dynamic Stability Control system consists of 5 main components, which should include:
- Wheel speed sensor
- Cornering brake control
- Steering wheel angle sensor
- Yaw rate sensor
When input signals are transmitted to the integrated control unit, the computer will issue a stability control module after comparing it with the steering angle sensor to get the engine output.
The system can reduce power or command the brake pedal, to help the vehicle return to a safe driving state quickly following different road conditions.
Dynamic Stability Control and Traction Control are also effective in reducing pressure and controlling brake fluid if there is a harmful impact on the car’s cylinders.
In addition, when there is a difference in dynamic force at the wheels, this system will activate and increase the oil pressure in the critical area.
However, one thing to note is that the locking system does not automatically act as a steering wheel angle sensor.
This system only works when the wheel is in danger of damage and the driver doesn’t turn it off.
What Causes DSC System Problems?
As the DSC on car relies on receiving input signals to understand what is happening around, faulty sensors, including the yaw rate sensor, longitudinal acceleration sensor, or wheel speed sensor, are the main causes.
A poor battery connection can be another reason. The system needs the power to function.
And if the battery terminals are loose or your car has a dead battery, it may not receive the voltage required to power the sensors and analyze the input to vehicle response.
Double-check your battery connections and tighten battery terminals if needed.
Another issue is a bad connection between the sensors and the electronic control unit. Wires and connections can get damaged or rusted over time.
This might result in intermittent or full communication failure between the sensors and the integrated control unit.
Finally, the DSC system can be turned off completely. To do so, hit the DSC button on the center console. The DSC system will not be able to keep your car steady if it is switched off.
Should I Turn Off The Dynamic Stability Control In My Car?
The function of the DSC system is to help the driver reduce the risk of an accident while on the road by maintaining balance control when the vehicle encounters adverse conditions.
When you start your automobile, it is turned on by default. You may disable the safety function. But most of the time, you’d better keep your traction control on.
When driving in severe rain, snowy or icy weather, or even in areas where the ground seems slippery, traction control and DSC will significantly improve your safety.
When driving, it’s critical to maintain traction control 99% of the time. However, the safety function may do more harm than good in other circumstances.
For example, keeping it off is best if you get stuck on uneven and soft surfaces, such as sand or snow. Traction control, in this case, may impair your driving if you find yourself spinning your wheels.
How to Tell If DSC Is Active?
When you start your car, the “DSC” dashboard indicator light will illuminate if the system is functioning properly. This indicator light flashes for a few seconds before turning off.
If the light is not switched on at all or illuminates after the engine is started, there is an issue with the system.
What Are Some Common Vehicle Stability Control Systems?
Each vehicle will be equipped with a different life-saving Vehicle Stability Control from its manufacturer.
However, they all generally have a similar structure and operating principle. Car manufacturers develop some DSC systems with different names, such as:
- Lexus – VSC (Vehicle Skid Control)
- BMW – DSC.
- Jaguar – DSC.
- Volkswagen – ESP (Electronic Stability Program).
- Audi – ESP (Electronic Stability Program).
- Volvo – DTSC (Dynamic Stability Traction Control)
- Porsche – PSM (Porsche Stability Management).
Depending on the vehicle type and control mechanism, the vehicle dynamic control system will have a sensor corresponding in design and control techniques.
Normally, car models should come with genuine accessories to ensure compatibility, and quality, and car owners can enjoy the best warranty policy.
What is DSC in a car?
DSC is designed to reduce reckless driving and advance auto safety by avoiding loss of control in adverse road conditions.
Through this post, we have learned about the working principle of the DSC system and some common problems this system faces.
With this active safety function and driving skills, you can be more confident in your driving experience.
Hopefully, this sharing will help you better understand the DSC meaning car and the system’s function to make safe choices and have high-performance driving.
