I can't believe how people get mixed up in this game make believe assists and real life electronic assists ...
SRF, AYC, ASM, TCS, ESP, DSC, EBD and so on ... they are all have one purpose, makes the driver less prone to mistakes, less burden, less skill needed, for more grip in every situation possible. In game, they do not resemble anything in real life, they never will, SRF is one of the major offender. Real life electronic assists works within limit of real life law of physics, game is "only" limited by the programmer and their preset limits of calculations via game engine ( really no comparison )
The term and unique implementation of AYC was designed and invented by Mitsubishi. Any similarity of name like yaw control is the general term of controlling yaw movement using electronic system, the method is unique to almost every car manufacturer as each is usually patented by respective company who implement it.
BMW uses individual brake force distribution to aid in yaw movement control to provide stability in cornering among other things - they call it DSC, while Mitsubishi uses electronic + electrohydraulic controlled differential to distribute/provide specific torque vectoring to each driven wheel in order to maximize traction to achieve minimum loss of cornering speed & greater stability. They are nothing alike, AYC is a specific design for AWD only system, BWM uses brake, traction control, a myriad of sensors which can be used on any type of drivetrain.
BMW's official DSC summary taken from their site :
Information comes a range of sensors monitoring wheel rotation, steering angle, lateral forces, pressure and yaw (degree of rotation around the vertical axis). A simulation model stored in the DSC control unit to ensure stability ("one-/two-track model") and can be compared information coming from the steering wheel and accelerator: if there is too great a difference between the model and how the vehicle is currently travelling, DSC acts to increase stability or traction.
The engine and brake management systems are targeted specifically; xDrive is also included in all-wheel drive vehicles. Reducing or increasing the engine torque or braking individual wheels can improve stability and traction. Active Steering’s integrated yaw regulation system can even help significantly reduce steering effort and the extent of DSC’s contribution to stability.
