Problems solved by technology

However, a limitation of conventional active seat belt controls is that the active seat belts are not activated when there is a danger of a rollover accident, such as when the Forward Collision Avoidance Assist (FCA) is not performing emergency braking or when the vehicle is going downhill or climbing a hill. normal operation
Also, when the FCA fails and a bump / collision occurs in a non-braking state, it is difficult for conventional active seat belt controls to actively control the seat belt

Abstract

A method of controlling an active seat belt includes: checking whether a seat belt is fastened; collecting driving information from sensors or driving assistance / safety systems installed in a vehicle; determining a safety state of the vehicle based on the driving information; checking whether an airbag is deployed ; and, in response to a safe state when the airbag is not deployed, outputting a motor control signal for restraint control of the seatbelt.

Description

[0001] This application is based on and claims priority to Korean Patent Application No. 10-2017-0175912 filed on December 20, 2017, which is hereby incorporated by reference as if fully set forth herein. technical field [0002] The present disclosure relates to devices and methods for controlling active seat belts in vehicles, and more particularly, to devices and methods for actively controlling active seat belts located in vehicle seats based on state information collected or detected during vehicle travel . Background technique [0003] Generally, a seat belt is an example of a safety device for elastically restraining a passenger's body to prevent serious injury in the event of a sudden impact due to a collision or impact during driving. The vehicle seat belt is operably connected to a seat belt indicator which, due to the importance of wearing the seat belt, informs the driver whether or not the seat belt is fastened. The seat belt indicator is configured in such a w...
