ABS,TC and ESP are called active safty (see inside)

In the automotive sector the term 'active safety' has traditionally referred to systems that help prevent accidents. For example, good visibility from the vehicle can be considered a component of active safety (the term Primary Safety is also used). This compares with passive safety (or Secondary Safety), which include features that may help mitigate the severity of accidents. However, a new generation of safety features that operate automatically, in response to sensor signals that give an understanding of the vehicle's state, are also being referred to as active safety systems. These systems, such as intelligent speed adaptation, ABS, ESC, brake assist, traction control, VSC, VDIM and seat belt pre-tensioning are active in the sense that they invoke an action in order to improve safety.
