  • Publication number: 20240157980
    Abstract: A method including: determining, based at least in part on plural data items originating in plural distinct sources, at least one estimated driving condition for each one of a plurality of road segments in a road network, each of the at least one estimated driving condition being determined for a future time interval; determining at least one route in the road network for a vehicle which includes a first road segment with a first estimated driving condition, determined for a first time interval, which satisfies a driving condition restriction for an automated system or automated feature of the vehicle, for an at least partially automated mode of the vehicle; and scheduling instructions for the vehicle including the at least one determined route such that the vehicle is capable of traversing the first road segment during the first time interval.

  • Patent number: 11797017
    Abstract: Embodiments of the invention relate to a method for controlling a fleet of at least two autonomous/remotely operated vehicles, wherein an embodiment of the method comprises: assigning to each of said at least two vehicles a predetermined route comprising a road segment which requires that a teleoperator of a remote operation station assists and/or drives the vehicle, determining a time overlap of the said road segments, and based on the determined time overlap, inserting a delay or a speedup in a preceding autonomous drive road segment of the predetermined route of at least one of said at least two autonomous/remotely operated vehicles so that said road segments no longer overlap in time.

  • Patent number: 11267479
    Abstract: A method for determining whether the driver of a vehicle is holding the steering wheel includes steps of repeatedly determining (S1) the steering wheel angle, repeatedly determining (S2) an error value based on a current determined steering wheel angle value and a previously determined steering wheel angle value; comparing (S3) a determined current error value with previously determined error values to determine a correlation between the error values; determining (S4a) that the driver is holding the steering wheel if the correlation between the error values is above a threshold value or if the driver is not holding the steering wheel if the correlation between the error values is below a threshold value. Also, a system for determining whether the driver of a vehicle is holding the steering wheel by performing the method. Also a computer program and a computer program product for practicing the method.

  • Patent number: 11056002
    Abstract: Method and control unit, for avoiding a potential collision between the vehicle and a Vulnerable Road User, VRU. The method comprises: predicting a future path of the vehicle; detecting the VRU and the position of the VRU; determining velocity of the detected VRU; predicting a future position of the detected VRU, based on the VRU position upon detection and the determined VRU velocity; and performing an action for avoiding a collision, when the predicted future position of the VRU is overlapping the predicted future path of the vehicle.

  • Publication number: 20180222475
    Abstract: Method and control unit for predicting a path of a vehicle are provided. The method comprises measuring velocity of the vehicle; measuring steering wheel angle (?sw); measuring steering wheel angle rate (??sw); calculating a future steering wheel angle (?sw), based on the measured steering wheel angle (?sw) and the measured steering wheel angle rate (??sw); calculating a future yaw rate (?) of the vehicle based on the measured velocity of the vehicle and the calculated future steering wheel angle (?sw); extrapolating a vehicle position of the vehicle in a set of future time frames, based on the calculated future yaw rate (?) and the vehicle velocity; and predicting the path of the vehicle based on the extrapolated vehicle positions in the set of future time frames.
