FIELD: machine building.SUBSTANCE: disclosed group of invention relates to device and method of providing assistance during driving. Driving aid device more appropriate controls need in assistance during driving, associated with avoidance of collision, and efficiently inhibits activation of optional aid during driving. Driving aid device performs assistance in avoiding of collision for vehicle relative to moving ahead vehicle, based on time to collision. Transverse speed variation calculation unit determines relative transverse speed. Storage unit saves steering time, which is time required for vehicle, to avoid moving ahead vehicle by means of steering. Storage unit stores activation threshold value, which is a threshold value to, determine aid activation during driving based on relative transverse speed. Aid control unit inhibits driving aid activation process in situation, when time to collision is equal to or larger than steering time.EFFECT: enabling higher safety during vehicle driving.11 cl, 19 dwg |
