Abstract

Disclosed are a collision damage mitigation system of a vehicle and a control method thereof. The collision damage mitigation system includes a forward sensor to detect a distance and relative speed between an owner's vehicle and a vehicle in front thereof, an electronic control unit to judge a degree of collision risk based on a Time-To-Collision (TTC) value upon receiving sensor information transmitted from the forward sensor, the TTC value being obtained by dividing the distance between the owner's vehicle and the vehicle in front thereof by the relative speed therebetewen, and to control implementation of at least one of collision warning, vehicle control, and inflation of an air bag based on the judged degree of collision risk, and an air bag drive unit to inflate the air bag, immediately before vehicle collision, in response to an air bag inflation signal from the electronic control unit.

Description

technical field [0001] Embodiments of the present invention relate to a vehicle collision damage mitigation system and a control method thereof. Background technique [0002] Generally, traffic accidents frequently occur when a driver loses concentration during running of a vehicle or when a vehicle in front suddenly stops. To reduce such accidents, collision damage mitigation systems have been proposed. a collision damage mitigation system designed to detect the distance between a radar-equipped vehicle and another vehicle in front of it and the relative speed between them to determine the degree of risk of collision between said two vehicles, and Depending on the degree of this risk of collision, the driver is warned of the risk of collision or, if necessary, automatic braking is implemented. [0003] However, when a vehicle collision occurs, conventional collision damage mitigation systems may not be able to reduce damage to the vehicle. Although it can alleviate the i...
