KR960024378A - Hazard automatic generator and method using acceleration sensor - Google Patents

Abstract

The present invention relates to a method for automatically generating a hazard using an acceleration sensor and a method for generating a hazard when a deceleration value is equal to or higher than a predetermined deceleration value by measuring a deceleration of a host vehicle using an acceleration sensor. In the case of emergency, the driver operates the hazard directly by hand, so in the case of emergency, the time to give warning to the following car may be delayed, and this signal is not generated by some drivers, causing a collision with the following car. The present invention reduces the risk of collision with a following vehicle by automatically generating a hazard when a deceleration is below a certain deceleration by using an acceleration sensor, and by removing this signal at a predetermined time or when the deceleration is above a certain deceleration. It is to be.
