Safety device operation timing control method and device

Abstract

In a safety device operation timing control device, if a collision avoidance operation in the longitudinal direction is determined to have been carried out, a configuration unit configures a first timing, which is a timing slower than a reference timing, which is a timing for operating the safety device, and meanwhile, if a collision avoidance operation in the horizontal direction is determined to have been carried out, the configuration unit configures a second timing, which is a timing later than the aforementioned reference timing. Further, in the case that a collision avoidance operation in the longitudinal direction and / or a collision avoidance operation in the horizontal direction is determined to have been carried out, then an operation determination unit makes a determination about whether or not to operate the safety device on the basis of the corresponding first timing and / or second timing.

Description

technical field [0001] The present invention relates to a safety device operation timing control method and device for controlling the operation timing of a safety device included in a self-vehicle based on the possibility of a collision between the self-vehicle and an object located in the traveling direction of the self-vehicle. Background technique [0002] Conventionally, there is known a pre-crash safety (PCS) system that reduces or prevents collision damage between an own vehicle and obstacles (objects) such as other vehicles, pedestrians, or road structures located in front of the own vehicle in the traveling direction. This PCS system calculates a time to collision (TTC) which is a margin time until the own vehicle collides with the obstacle based on the relative distance between the own vehicle and the obstacle and the relative speed or relative acceleration. Then, based on the calculated predicted collision time, the PCS system notifies the driver of the own vehicl...

AI Technical Summary

Problems solved by technology

[0005] The conventional PCS system may activate the safety device despite the driver's intention to avoid a collision. In this case, the driver may be troubled by the operation of the safety device.
