▶ 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.
▶ Oversteering
Oversteering is when the steering wheel is
steered to a certain angle during driving and
the rear tires slip outward losing traction.
When compared with
vehicles, the controlling of the vehicle is
difficult 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 oversteering
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 oversteering with the yaw rate sensor
and the lateral sensor.
Then the ESP system applies the brake at
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 he or she
intends.
