摘要： A computer-implemented method and a device for controlling a lane support system of a vehicle are disclosed. The method comprises obtaining data indicative of a driver of the vehicle being in an inattentive state, and determining an intended path of the driver at a point in time when the driver enters the inattentive state. The method further comprise determining an unintended lateral deviation from the intended path by computing a function representative of a lateral deviation from the intended path of the driver. Moreover, the function is dependent upon at least one of a change in steering wheel angle while the driver is in the inattentive state, and a change in road geometry along the vehicle's traveling direction while the driver is in the inattentive state. The method further comprises activating the lane support system when the determined unintended lateral deviation violates a threshold value, wherein the lane support system is configured to output a warning to the driver and/or to execute an intervention so to control a steering of the vehicle upon detection of a lane departure of the vehicle.

The path-adapting system determines (1001) conditions of a liquid and/or solid loose material in the air and/or on the road surface in vicinity of the host vehicle based on collected input data. The path-adapting system further determines (1002) movement attributes in relation to the host vehicle, of at least a first object (3) in host vehicle surroundings captured with support from one or more surrounding detecting sensors (23) onboard the host vehicle. Moreover, the path-adapting system determines (1003) based on said conditions and said movement attributes, at least a first estimated upcoming host vehicle position (4) occurring at an estimated upcoming at least first time instance (Te) at which the at least first detected object is estimated to direct said material onto the host vehicle and/or the host vehicle is estimated to direct said material onto the at least first detected object. Furthermore, the path-adapting system determines (1005) a driving path (6) intended for the host vehicle, altering for the at least first time instance the at least first estimated upcoming host vehicle position to a modified host vehicle position (7) mitigating said estimated directing of the material.
