Adaptive cruise control system for automotive vehicle
First Claim
1. An adaptive cruise control system for an automotive vehicle, comprising:
- a trajectory determination section to collect trajectory information used to determine a future trajectory of the vehicle;
a driving state determination section to collect vehicle information used to determine a driving state of the vehicle;
an output section to change an operating condition of the vehicle; and
a control unit in operative communication with the trajectory determination section, the driving state determination section, and the output section, the control unit being configured to perform the following;
determining the vehicle future trajectory;
determining the vehicle driving state;
estimating in accordance with the vehicle future trajectory and the vehicle driving state a future driver load imposed on a driver of the vehicle during the vehicle traveling through a target section of the vehicle future trajectory; and
changing the vehicle operating condition in accordance with the estimated future driver load, so that the future driver load decreases.

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.
