Anti-collision auxiliary device capable of changing intervention control reference and method thereof

Abstract

PURPOSE: A collision avoidance auxiliary device and a method for changing a control intervening reference are provided to change a reference threshold depending on reflected vehicular driving conditions in order to determine driver's will for collision avoidance steering, thereby avoiding vehicle collisions based on the changed reference threshold. CONSTITUTION: A collision avoidance auxiliary method for changing a control intervening reference includes: a step of recognizing the states and the driving conditions of a vehicle based on the detected information transmitted from sensors mounted on the vehicle; a step of determining whether or not a predetermined reference torque value is reset depending on the recognized information, and then resetting the reference torque value in which the recognized information is reflected if the predetermined reference torque value is determined to be reset; and a step of determining driver's will for the direction of collision avoidance steering based on the reset reference torque value, and then outputting a control demand for driving the vehicle in the determined direction.

Description

technical field [0001] The present invention relates to an anti-collision auxiliary device capable of changing the intervention control standard and its method, and more particularly relates to a device and method capable of changing the intervention control standard for collision prevention. Background technique [0002] In the past, the anti-collision assistance device judged the possibility of a vehicle collision inside the controller, first controlled the sudden braking, and during the sudden braking, if the side lane was judged to be empty, the steering angle was used to avoid the collision of the vehicle. [0003] For example, anti-collision auxiliary devices that avoid and prevent collisions with obstacles through steering and braking of vehicles, such as figure 1 shown, is the use of cameras, radar or fusion systems of these sensors, such as figure 2 As shown, when a collision is predicted, an appropriate target evasion trajectory is generated, and based on this, a...

[0005] However, because the steering column torque is changed according to the driving situation, in order to judge such a situation, it is necessary to judge the steering column torque reference setting value (threshold) of the steering will, which is variable, but the steering torque that is not variable When the reference setting value (threshold) is changed as a reference, there may be a problem that the driver's will will be misrecognized, which will cause the anti-collision control system to operate incorrectly, and the vehicle control will be performed regardless of the driver's will.
