▶Understeering
Understeering is when the steering wheel is steered to a certain angle during driving and the
front tires slip toward the reverse direction of the desired direction. Generally, vehicles are
designed to have under steering. The vehicle can return back to inside of cornering line when
the steering wheel is steered toward the inside even when the vehicle front is slipped outward.
As the centrifugal force increases, the tires can easily lose the traction and the vehicle tends to
slip outward when the curve angle gets bigger and the speed increases.
▶ESP controls during under steering
The ESP system recognizes the directional angle with the steering wheel angle sensor and
senses the slipping route that occurs reversely against the vehicle cornering direction during
understeering with the yaw rate sensor and the lateral sensor. Then the ESP system applies
the brake at the rear inner 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 driver intends.
