摘要： The invention relates to a method for analyzing localization errors, wherein the method includes the steps of obtaining relative positions and absolute positions of an object moving within a mapped environment, which are generated sequentially over time, calculating differences between the relative positions and absolute positions to determine sequential localization errors, and decomposing the localization errors into a systematic error that is dependent on the orientation of the object and into a systematic error that is independent on the orientation of the object by analyzing the intrinsic dynamics of the localization errors.

摘要： Control commands in a system and method for autonomously driving a vehicle or partially autonomously driving a vehicle are generated on the basis of an environment representation, which is generated from sensor signal of a sensing means. The environment representation where ambiguous objects are identified is such that information obtained from the driver of the vehicle are added. The system generates an information request. Additional information is extracted and accumulated in the environment representation map. Traffic is then determined and suitable control signals for the vehicles are generated. In case no ambiguous objects are included in the environment representation but the system is not capable of deciding on traffic, the driver is asked to disambiguate the situation or to instruct on dealing with the traffic.

摘要： The invention relates to a system and method for assisting a driver in driving a vehicle. First information on an environment of the vehicle is obtained and an instruction from the vehicle driver is received. An evaluation task defining an aspect of a current traffic situation encountered by the vehicle and to be evaluated is defined from the received instruction. An evaluation of the obtained information according to the evaluation task is performed, and an evaluation result is generated. Other aspects of the traffic situation and their relation to the aspect defined in the task are then evaluated additionally. Finally an information on the basis of the evaluation result and the other determined aspects is generated and output.

摘要： A system corrects errors of a measurement system. The system comprises base measurement system BS and a correction system. BS sensor data is acquired and provided to an algorithm. The data is stored associated with a time stamp indicating time of sensing. Output values are calculated and stored with time stamps indicating time of the sensor data upon which the output values are calculated. Data having corresponding time stamps are supplied to a filter where correction values and correction increments are calculated. The correction increments reflect the change of error in a base system output value over time due to integration or summing up BS sensor data errors in the processing algorithm. The correction values are applied to the BS data and corrected base navigation output values are calculated. These output values are corrected by the correction increments. Output values of the processing algorithm are further processed in succeeding applications.

摘要： A method for improving ergonomics of a vehicle obtains a first information defining an initial cockpit configuration. Further, information on a cockpit user's shape and information of a seat and steering wheel position which the user typically uses while driving, are obtained. This information is fed into a bio-mechanical simulation which carries out the simulation based upon the information defining the initial cockpit configuration, the user's shape and the user's seat and steering wheel position. In the bio-mechanical simulation, an ergonomic quality criteria is calculated for reaching movements during driving. Based upon the simulation result which is the quality criteria, the cockpit configuration is changed. The bio-mechanical simulation and the changing of the cockpit configuration in the optimization process is then repeated until a predetermined stop condition is fulfilled. The cockpit configuration which is achieved at that point in time is output as final cockpit-configuration.

摘要： The invention regards an autonomous working machine comprising drive means, current position estimation means, control means including a driving control unit and a camera. With aid of the current position estimation means the current position of the autonomous working machine is estimated. Furthermore, the driving control unit generates driving commands for the driving means on the basis of an intended movement of the autonomous working machine and the estimated current position. The camera is configured to capture images of the environment of the working machine. For estimating the current position, the current position estimation means is formed by the control means, which is configured to apply visual odometry on the captured images for estimating the current position of the working machine.

摘要： A method and a system for improving a traffic participant's attention is such that, at first, information on the traffic scene that is encountered by the traffic participant is obtained. From the obtained information a traffic situation development is predicted. A measure for at least on future risk in the predicted traffic situation development is determined and a communication with the traffic participant is started. The communication comprises a first step of notifying the traffic participant and a second step of providing additional information in response to the traffic participants reaction to the notification which includes some information on the determined future risk.

摘要： A method for computationally predicting future movement behavior of a target object and program includes producing sensor data by at least one sensor physically sensing the environment of a host vehicle, and computing a plurality of movement behavior alternatives of the target object sensed by the sensors. The computing includes predicting movement behaviors of the target object applying context based prediction using at least one indirect indicator and/or indicator combinations derived from senor data. In the context based prediction, a probability that the target object will execute a movement behavior is estimated. A future position of the target object is estimated and a signal representing the estimated future position is outputted. At least one history indicator for a movement behavior alternative is generated for a current point in time using at least one indicator of an indirect indicator at a point in the past.
