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.
Claims12
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) module
- determining whether or not the vehicle is deviated from a lane, and
- sending a steering angle control command to the driving system upon determination that the vehicle is deviated from the lane;
- and
- an integrative control module
- calculating 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, and
- instructing the BSD module to send a side brake control command to the driving system and
- instructing 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.
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.
