Electronic Stability Program (ESP) *
ESP can effectively reduce the risk of vehicle
sliding.
Operating Principle of ESP
ESP confirms the driver's driving intention
according to steering wheel angle and vehicle
speed, and constantly compares the information
with actual driving condition. If the vehicle deviates
from the normal running route (e.g., side skidding),
the ESP will correct it by applying a brakeforce to
the appropriate wheels.
The ESP can be used to recover the stable
driving state through the twisting force generated
by braking. If the vehicle tends to oversteer (i.e.
drift), the system will mainly exert the brakeforce on
the front wheel at the outer bending. If the vehicle
tends to understeer (i.e. excessive turning radius),
the system will mainly exert the brakeforce on the
rear wheel at the inner bending.
Vehicle not equipped with ESP sideslips and
deviates from the normal route during driving.
Vehicle equipped with ESP can correct the
brakeforce according to the sideslip amount to
prevent deviating from the route.
