Abstract:
1. A safety device for a vehicle comprising: a distance information detecting element for detecting a distance to a crash object and a relative speed relative to the crash object; a passenger protection element for lightening crash damage by completing a transition to a passenger protecting state after a predetermined actuation rise time elapses from an actuation start time; a calculation and control element for ordering a start of actuation of the passenger protection element, wherein actuation is started when an available time before a crash, which is the time to an estimated crash time calculated on the basis of the detected distance and relative speed, has fallen to a predetermined first threshold time, and wherein the predetermined first threshold time is set to be equal to or longer than said actuation rise time; and a deceleration rate information detecting element for detecting deceleration rate information relating to a deceleration rate that is a rate of change of said relative speed, said calculation and control element corrects said actuation start time on the basis of said deceleration rate information.
