AI Technical Summary

Technical Problem

Current Full Speed Range Adaptive Cruise Control (FSRACC) systems require driver intervention after a predetermined time if a stopped vehicle is detected, limiting their ability to autonomously resume movement without user input.

Method used

The system determines the reliability of sensor detection of a target vehicle by assessing the number and type of sensors, allowing the vehicle to autonomously resume movement based on confidence levels, with different time thresholds for varying levels of sensor confidence, thereby eliminating the need for driver input.

Benefits of technology

Enables the vehicle to autonomously resume adaptive cruise control based on sensor confidence levels, enhancing user convenience and system reliability by reducing the need for manual intervention.

Abstract

Adaptive cruise control system for the entire speed range for a host vehicle (202), wherein the system comprises: a plurality of sensors in the host vehicle (202), each of the plurality of sensors generating a signal; a memory (38) configured to contain one or more executable instructions, and a processor (36) configured to execute the executable instructions, wherein the executable instructions enable the processor (36): to detect a target vehicle (204) as stopped along a route based on at least one of the signals from the multitude of sensors; to cause the host vehicle (202) to stop at a distance from the target vehicle (204); and to detect the target vehicle (204) moving again along the route after the host vehicle (202) has stopped, based on at least one of the signals from the multitude of sensors; characterized by the fact that the executable instructions further enable the processor (36): to determine whether a first predetermined time interval (304) has elapsed between the stopping and the re-movement of the host vehicle (202), in which case to determine whether one or more sensors detect the target vehicle (204), and in which case to cause the host vehicle (202) to move again; and to determine whether a second predetermined time interval (308), longer than the first predetermined time interval (304), has elapsed between the stopping and the re-moving of the host vehicle (202), in which case to determine whether two or more sensors detect the target vehicle (204), and in which case to cause the host vehicle (202) to move again.
