Abstract
A method for lane-keeping control of a lane-keeping support system provides a current command indicative of steering torque assist needed to steer a vehicle in following a target line between lane markings on a roadway during driving in lane-keeping control (LKC) mode. A map has two sets of limit data against a range of values of lateral acceleration to which the vehicle is subject, between which sets of limit data there is a range of values of the command during various phases of steering the vehicle to turn in the LKC mode. In order to compensate for undesired effect caused by any deviation of the range of values of the current command due to the presence of continuous disturbance, the two sets of limit data are corrected. To determine driver steering intervention, the instantaneous value of the current command is compared to two limit values established out of the corrected two sets of limit data.
