Abstract:
1. An adaptive cruise control system for a host motor vehicle, comprising: a sensor system for acquiring data of a present time point regarding a target object and data regarding the host vehicle; an actuator system for controlling the longitudinal movement of the host vehicle; a controller for intervening in the operation of the actuator system within at least one predetermined intervention range in order to maintain a predetermined controlled target distance of the present time point to the target object; an output device for issuing a take-over request to a driver of the host vehicle if the predetermined controlled target distance of the present time point cannot be maintained; and a prediction system for predicting a conflict situation in which the predetermined controlled target distance cannot be maintained, the prediction system including: wherein the prediction system initiates the take-over request to be issued by the output device before the conflict situation occurs, and wherein the prediction system calculates from the predicted values an anticipated setpoint distance and an anticipated actual distance between the target object and the host vehicle at the future prediction time point, wherein the prediction system initiates the take-over request to be issued by the output device if the relationship between the anticipated setpoint distance and the anticipated actual distance satisfies a predefined initiation criterion, wherein the initiation criterion is a threshold value for the quotient of the anticipated actual distance and the anticipated setpoint distance, and wherein the adaptation module is configured to dynamically vary the future prediction time point, dependent on data provided by the sensor system.
