AI Technical Summary

Technical Problem

Conventional vehicle emergency stop systems risk prematurely ending emergency stop control due to minor collisions or changes in steering and braking inputs caused by driver posture changes during collisions, potentially compromising safety.

Method used

The system continuously monitors driving operation devices and collision detection, ensuring emergency stop control continues if operation is detected within specific time thresholds after collision detection, and adjusts braking force levels based on collision severity.

Benefits of technology

Enhances vehicle safety by preventing premature termination of emergency stop control during minor collisions, maintaining safety even when driver input is unintentional.

Abstract

To provide an emergency stop system that can further improve safety of an own vehicle.SOLUTION: A vehicle emergency stop system 1 includes a control device configured to start execution of emergency stop control of bringing an own vehicle to an emergency stop by performing braking control of the own vehicle when an operation of a driving operation device of the own vehicle is not detected continuously for a predetermined period of time, and to end the execution of the emergency stop control when the operation is detected during the execution of the emergency stop control. The control device continues the emergency stop control when a collision of the own vehicle with a target object is detected during the execution of the emergency stop control and the operation is detected within a first predetermined period of time from a first time point at which the collision is detected and when the operation is detected during the execution of the emergency stop control and the collision is detected within a second predetermined period of time from a second time point at which the operation is detected.SELECTED DRAWING: Figure 2A
