Integrative method and system for controlling blind spot detection system and lane keeping assist system
First Claim
Patent Images
1. An integrative control system, comprising:
- a driving system performing steering and driving of a vehicle;
a blind spot detection (BSD) module calculating a time-to-collision against another vehicle, when said another vehicle is positioned in a blind spot of the vehicle;
a lane keeping assist (LKA) moduledetermining whether or not the vehicle is deviated from a lane, andsending a steering angle control command to the driving system upon determination that the vehicle is deviated from the lane; and
an integrative control modulecalculating an estimated lateral distance when the vehicle is deviated from the lane and said another vehicle is positioned in the blind spot, by using the time-to-collision, andinstructing the BSD module to send a side brake control command to the driving system andinstructing the LKA module to send the steering angle control command to the driving system when the estimated lateral distance is equal to or greater than a predetermined value.

Abstract
An integrative control system and a method for controlling a blind spot detection system (BSDS) and a lane keeping assist system (LKAS) for stable driving of a vehicle are provided, in which, when the vehicle is deviated from its lane and another vehicle is positioned in a blind spot, an estimated lateral distance is calculated using time-to-collision, and side brake control by the ABSD system and steering angle control by the LKAS are performed based on the estimated lateral distance.

7. An integrative control method of a blind spot detection system (BSDS) and a lane keeping assist system (LKAS) mounted to a vehicle, comprising:
-
detecting, by the LKAS, a deviation from a lane; detecting, by the BSDS, positioning of another vehicle in a blind spot of the vehicle and calculating a time-to-collision against said another vehicle; calculating an estimated lateral distance using the time-to-collision; and when the estimated lateral distance is equal to or greater than a predetermined value, instructing the BSDS to send a side brake control command to a driving system and instructing the LKAS to send a steering angle control command to the driving system. - View Dependent Claims (8, 9, 10, 11, 12)
