Device for making safe a stationary vehicle in the presence of a risk of collision from the rear

摘要

A safety device (DS) equips a first vehicle (V1) comprising analysis means (MA1-MA2) suitable for analyzing its environment. This device (DS) comprises control means (MC) designed, when the first vehicle (V1) is stationary and has its contact open, and in the presence of a risk of collision of the first vehicle (V1) by a second vehicle (V2) travelling behind it, to determine whether there exists in this analysed environment at least one empty zone (ZV1) accessible by the first vehicle (V1), and, in the affirmative, to determine for the latter (V1) a trajectory in this empty zone (ZV1) suitable at least for limiting the consequences of this collision, and then to trigger a displacement of the first vehicle (V1) according to this determined trajectory. The device considers the presence of a third vehicle (V3) travelling on another lane (VC3), in the environment of the first vehicle.
