(2) Over steering
What is oversteering?
Oversteer is a term of a condition in which the steering wheel is steered to a certain angle during
driving and the rear tires slip outward losing traction.
Compared to understeering vehicles, it is hard to control the vehicle during cornering and the
vehicle can spin due to rear wheel moment when the rear tires lose traction and the vehicle speed
increases.
ESP controls during oversteer
The ESP system recognizes the directional angle with the steering wheel angle sensor and senses
the slipping route that occurs towards the vehicle cornering direction during oversteer with the
yaw rate sensor and lateral sensor. Then the ESP system applies the braking force to the front
outer wheel to compensate the yaw moment value. In this way, the vehicle does not lose its
driving direction and the driver can steer the vehicle as intended.
