An adaptive control system for an automotive vehicle, which warns of a
driver and/or reduces the vehicle speed in consideration of a future
trajectory. Receiving from a navigation system node information about
nodes within a preview section, a control unit calculates a path radius
at each of the nodes within the preview section, and identifies curve
sections in accordance with the path radius of the preview section.
Subsequently, the control unit estimates a lateral acceleration based on
the current vehicle speed and the path radius. Subsequently, the control
unit determines an estimated total driver load in accordance with the
estimated lateral acceleration. Subsequently, the control unit determines
a reference total driver load which is applied to the driver during the
host vehicle traveling at an allowable cornering speed. Subsequently, the
control unit calculates a driver load deviation between the estimated
total driver load and the reference total driver load.
