How Electronic Stability Control Works

ESP has various options for stabilising the vehicle:

Via specific brake intervention

•

• Via intervention in the engine management system and additionally

• Via intervention in the gearbox management system (in vehicles with automatic gearboxes) and into the four-wheel drive control system

By evaluating the input signals and comparing the vehicle's actual/nominal behaviour, the ABS/ESP control unit recognises an unstable driving situation. In certain situations, it is necessary for ESP to intervene in the engine management system. If, for example, a driver wishes to accelerate in an unstable driving situation, this is prevented via ESP's intervention in the engine management system.
