A VEHICLE DYNAMIC CONTROL . IT IS A DRIVER / VEHICLE AID TO CONTROL AND ASSIST THE DRIVER TO SAFELY CONTROL THE VEHICLE IN A STABLE AND OPTIMISED CONDITION. IT MONITORS DRIVER INPUT AND CONDITIONS EFFECTING THE VEHICLE BY MEANS OF ELECTRICAL CIRCUITS AND SENSORS, MAKING ADJUSTMENTS AND APPLYING THE BRAKES DURING MANOEUVRES THAT ENDANGER THE SAFETY OF THE DRIVER AND VEHICLE. IT MANAGES STABILITY BY CONTROLLING BRAKE PRESSURE AND TORQUES FROM ITS POWER SOURCE BY DETECTING YAW RATE ACCELERATION, STEERING ANGLE AND WHEEL SPEED.THE CONTROL UNIT DETERMINES THE VEHICLES CONDITION BY SENSING THE OUTPUT FROM THE SENSOR SIGNAL. AN AMOUNT OF CAREFULLY CALCULATED BRAKE PRESSURE IS AUTOMATICALLY APPLIED TO INDIVIDUAL WHEELS TO CORRECT THE VEHICLES BEHAVOIUR FROM AN OVERSTEER OR UNDERSTEER SITUATION AND ALSO MODERATES THE BRAKE PRESSURE TO PREVENT WHEEL SKIDDING AND THE TORQUE FROM THE POWER SOURCE TO RECOVER THE LOSS OF TRACTION. COMPRISES OF VALVES, CIRCUIT BOARD, AND PART OF THE VEHICLES BRAKE FLUID.IT IS MADE FROM STEELS AND ALUMINIUM AND ELECTRICAL COMPONENTS. IT HAS THREE BASIC FUNCTIONS, ABS PREVENTING THE WHEEL LOCK AND UNCONTROLLED SKIDDING, TCS OPTIMISE GRIP AND STABILITY DURING ACCELERATION, VDC PREVENTING UNSTABLE BEHAVIOUR AND LOSS OF STEERING CONTROL. ADDITIONAL FUNCTIONS, HSA PREVENTING ROLL BACK IN THE CASE OF HILL STARTS., HDC PREVENTING UNSTABLE BEHAVIOUR BY WHEEL LOCK OR INSUFFICIENT ENGINE - DRAG IN CASE OF DOWN HILL.
