– There are the following functions in assist control
Item
Function
Calculates the assist current from the steering torque value and the
vehicle speed, and actuates the motor
Basic Control
Inertia Compensation Improves the starting movement of the motor when the driver starts to
Control
turn the steering wheel
During the short interval between the time the driver fully turns the
steering wheel and the wheels try to recover, this control assists the
recovery force
Recovery Control
Regulates the amount of assist when the driver turns the steering wheel
while driving at high speeds, thus damping the changes in the yaw rate
of the vehicle body
Damper Control
Estimates the motor temp. based on the amperage and the current
duration . If the temp. exceeds the standard, it limits the amperage to
prevent the motor from overheating
System Overheat
Protection Control
Cooperative Control
with EPS
Controls EPS system in order to facilitate the driver to operate the
steering in a direction that stabilizes the vehicle during VSC operating
