What is DSC? DSC, short for Dynamic Stability Control is a suspension control system which goes beyond the single components of ABS, Cornering Brake Control (CBC) and Automatic Stability Control. It works by monitoring each wheel speed individually along with yaw rate and longitudinal and lateral acceleration through various sensor.
Dynamic Stability Control (DSC) is BMW’s version of this safety net on your car. It’s automatically activated each time you start your BMW.
The Dynamic Stability Control module also receives information from vehicle speed and engine speed, throttle position, brake pedal position/force and the steering angle sensor. All of this information collected is fed to the DSC control module and process.
The DSC computer constantly calculates an ideal driving condition that is compared with the current status. If the vehicle oversteers or understeers, the calculated ideal deviates from the measured status, and DSC will intervene within a few milliseconds via the engine management system by either applying brakes at different wheels, cutting fuel, and a few other methods that are too detailed for this short presentation
Dynamic Stability Control is a setting that has the ability to keep your BMW in line within the laws of physics. It’s a controlled, keep the car on the in intended path kind of setting which is what you want the majority of the time. The DSC system will use the brakes, individually, if needed, to keep a wheel from slipping if power is over coming grip.
Dynamic Stability Control can even decrease the power to the wheel if it detects wheel slip. Add the all-wheel drive system and it gets even more complex. Essentially what DSC means is no tail out drifting and no donuts in the snow. It has the ability to sense if you are about to spin the car and intervene again by monitoring the yaw of the car, the input of the steering wheel and the gas pedal.
DSC is a great safety feature in any car and it has and will save many cars and their passengers.
