Abstract
A lane keeping assist system (LKAS) is equipped with a compensator capable of solving the problem in which video data, which is measured by a video sensor, the processing speed of which is lower than the data processing speed of the LKAS, is repeatedly used, thereby improving the kinematic characteristics of a vehicle and lane-keeping control performance.
Claims6
A lane-keeping assist system (LKAS) for a vehicle, comprising:
- a video sensor unit for capturing video image or images outside of the vehicle and measuring location information of the vehicle and a curvature (ρp) of a lane with respect to a measuring point;
- a sensor unit for measuring a variable value or values related to one or more kinematic characteristics of the vehicle;
- a control unit for performing lane keeping control based on the location information, the lane curvature and the variable value or values related to the kinematic characteristics;
- and
- a compensation unit for estimating a deviation angle (θp) and a deviation distance (yp) based on data from the video sensor unit, the sensor unit and the control unit in a period that is a control data processing period of the control unit but is not a measurement period of the video sensor unit, and transmitting the estimated values to the control unit.
