Abstract
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.
