What is the purpose of using the ESP system in a passenger car?

Correct answer
C. Stabilizing the movement of the vehicle when driving along the curve.
Explanation
The ESP system stabilises the movement of the vehicle when driving around a bend - answer C. Preventing the wheels from locking when braking (B) is the job of ABS, and skidding during engine braking (A) is controlled by MSR.
ESP compares what the driver is doing (the steering wheel angle) with what the car is actually doing (rotation around its vertical axis, sideways acceleration). When the front of the car starts to slide out of the bend or the rear starts to slide sideways, the system itself brakes individual wheels and, if necessary, reduces engine power, bringing the car back onto the path chosen with the steering wheel. It is one of the most effective safety systems, but it does not change physics: it will not save you if you enter a bend too fast.
