SENSOTRONIC BRAKING SYSTEM (SBC)

When it comes time to stop a vehicle, most drivers slowly press on the brake pedal. Even during an emergency situation, studies have shown that almost all drivers will press only partially on the brake pedal for the first few milliseconds until their brain has time to analyze the situation and then the brake pedal is pressed firmly. This slight delay in braking enables the vehicle to travel several meters further and can cause an accident. There are several other factors that delay the vehicle’s response to a braking situation.
Mercedes-Benz is trying to reduce or eliminate as much as possible these factors with their new brake systems. They call it Sensotronic Brake Control.
Mercedes-Benz first introduced the Sensotronic brake system on their SL-Class sports car.
The brake system is integrated into the car’s stability control and traction control systems to predict the amount of braking force required at each wheel of the car. Rather than simply reacting to the slip of a tire on the road, the brake controller anticipates the maximum potential braking force all the time the car is rolling down the road. This ensures optimum braking performance at each wheel when needed.
Actual brake application begins long before the driver pushes on the brake pedal. By monitoring the accelerator pedal position, the brake computer can measure the rate at which a driver releases the pedal.
 If a driver is removing their foot quickly, then it could be in response to an emergency situation.
 The brake controller reacts by applying slight hydraulic pressure to each brake caliper to move the brake pads toward the brake rotor, eliminating any delay in applying braking force.
 By now, the driver has started to step on the brake pedal but probably not firm enough for an emergency stop.


 The computer measures the rate of brake pedal application by the driver and if the response is rapid, the computer will apply the brakes fully, even before the driver realizes that maximum braking effort is required.
 The computer can vary the amount of hydraulic pressure at each wheel to provide maximum deceleration even when the vehicle is on a turn.
