Electronic Stability Program (ESP)*

The ESP electronic stability program supports the driver in critical driving situations such as skidding or imminent tipping over when driving too fast in curves. A vehicle with ESP is also fitted with a steering angle sensor, yawing rate sensor and an acceleration sensor. An ESP control unit with the following two functions is integrated in the electronics architecture:

Dynamic stability program (DSP)

The dynamic stability program prevents understeer (front wheel slide) by braking the inner rear wheel. Oversteer (rear skid) is prevented by braking the outer front wheel.

Roll-over prevention (ROP)

Before critical lateral accelerations are reached, the speed is preventively reduced by torque reduction or braking.


  • Preventive speed reduction in critical lateral acceleration avoids dangerous driving situations.
  • Strong braking of the entire vehicle with lifting an inner wheel prevents tipping over with frequently serious repercussions for people and materials.
  • Compensatory braking supports the driver in critical driving conditions.
  • Accident avoidance always means reducing downtimes, safely bringing passengers to their destination and not endangering the health of the driver, passengers and other road users.

* Within the limits of the system.
