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. The electronic stability program ESP 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 fitted with a steering angle sensor, yaw rate sensor and an acceleration sensor.
If the vehicle understeers (pushes over the front wheels), the Dynamic Stability Program (DSP) compensates by braking the inside rear wheel.
Oversteer (rear skid) is prevented by braking the outer front wheel.
Before reaching a critical lateral acceleration, the Roll-Over-Prevention (ROP) reduces the speed preventively by engine torque reduction or braking.
