  • Patent number: 11778941
    Abstract: A system comprising an autonomous mobile device and a base station connected to a boundary wire is configured to transmit information from the base station to the autonomous mobile device. The base station is configured to generate a radio signal to be emitted by the boundary wire, wherein the autonomous mobile device is configured to autonomously drive within a working area based on the signal emitted by the boundary wire. The base station on the other hand is configured to encode data and/or commands into the radio signal which is then emitted by the boundary wire. The autonomous mobile device receive the emitted radio signal and is configured to decode the encoded data and/or commands in order to retrieve the original information.

  • Publication number: 20210043012
    Abstract: A vehicle transmits vehicle data to an observer entity when the vehicle and the observer entity are in proximity. The vehicle data includes unique vehicle identification information; proximity is defined by an upper threshold for a distance between the vehicle and the observer entity. The observer entity adds data to the vehicle data, the added data including an indication of a position of the observer entity and a time stamp indicating a time of reception of the vehicle data to generate joint data. The joint data is transmitted to an external database and the aforementioned steps are repeated. From the added data a usage estimation value is calculated which is a measure for usage of the vehicle and which is compared with the vehicle usage data retrieved from the vehicle. Information on validity of the vehicle usage data based on the comparison result is generated and output.

  • Patent number: 10824163
    Abstract: A method and a system can generate a representation of a working area of an autonomous lawn mower. The system can include an autonomous lawn mower and a base station, and a boundary wire forming a closed loop which can be connected with the base station. The lawn mower and the base station interact such that the lawn mower can determine whether it is in its home position, a predetermined position that is taken when the mower returns to the base station. The lawn mower further includes a memory, for storing values from a movement sensor. A trajectory is generated based on the values, wherein a processor is configured to calculate an error between the position and orientation according to the trajectory and the home position. This total position error and total orientation error is then used to correct the position and corresponding orientations of the trajectory.

  • Publication number: 20190377352
    Abstract: A method and vehicle for assisting in controlling an ego-vehicle determines a situation currently encountered by the ego-vehicle comprising the ego-vehicle and another vehicle. Probabilities of future behaviors of the other vehicle are computed based on the current situation. Potential future behaviors of the ego-vehicle are determined and probabilities of a various possible future situations are computed based on combinations of the predicted future behaviors of the other vehicle and the potential future behaviors of the ego-vehicle. Trajectories for associated behaviors are optimized for the ego-vehicle for some of these possible future situations and a trajectory is selected based a future situation probability. Since each trajectory is associated with one potential future behavior of the ego-vehicle, selection of a trajectory means a selection of a particular behavior.

  • Patent number: 9878710
    Abstract: The invention regards a method for improving performance of a method for computationally predicting a future state of a target object, a driver assistance system and a vehicle with such driver assistance system. First data describing a traffic environment including a target object is acquired. On the basis of the acquired data at least one prediction step for estimating a future state of an object in the traffic environment is performed and a signal indicative of a prediction result describing an estimated future state of the target object and/or an ego vehicle is generated. An actual state of the target object and/or the ego vehicle is observed and quality of the prediction by comparing the observed actual state and the prediction result is estimated. Finally the prediction result and/or parameters of the prediction algorithm is adapted.

  • Patent number: 9669872
    Abstract: A system and method assists a driver of a host vehicle in potential lane change situations. The method includes producing sensor data by a sensor physically sensing the environment of the host vehicle, predicting future movement behavior of at least one sensed vehicle, and determining whether a gap on a neighboring lane of the host vehicle exists. If the neighboring lane of the host vehicle would fit better for the predicted future movement behavior, a recommendation information signal is generated. Feasibility is determined by combining the determination result of the existence of a gap and the predicted future behavior. A notification for the host vehicle is output or, if lane change is feasible, signals for performing autonomous lane change based upon the recommendation information signal by the host vehicle are output.

  • Patent number: 9566981
    Abstract: A method predicts trajectories of traffic objects to avoid collisions. The method estimates the probability for at least two traffic objects to collide, and predicts a potential movement of the traffic objects presumably involved in the collision after the collision. This information about a potential movement of the traffic objects can be used to plan a suitable trajectory path of an evasion maneuver for a host-vehicle employing the method. A system detects the collision situation and applies crash situation models to predict the future dynamic properties of other traffic objects that collide or are about to collide with each other. The method and system applies specific crash models like collision models, models derived from crash simulations and tests or models of human reactions in emergency situations.

  • Patent number: 9501935
    Abstract: In an intelligent forward collision warning system that takes into account not only a first preceding vehicle traveling immediately ahead of the ego vehicle but also a second preceding vehicle traveling immediately ahead of the first preceding vehicle, a warning signal is produced upon detecting a critical state of the first or second preceding vehicle or an external condition that is predicted to cause the first preceding vehicle and the ego vehicle to be in a same lane with the first time to collision (TTC) below a prescribed value.

  • Patent number: 9313462
    Abstract: A method for detecting the position of a target object in the environment of a host vehicle. The method may include receiving a first position of the target object as detected by an object position sensor which emits waves and receives the waves that are reflected back by the target object, and receiving an image containing the target object as detected by an image sensor. The method may also include projecting the first position on the image, and refining the first position by computing a second refined position of the target object on the basis of a symmetry search within the image.
