A vehicle driver assist system includes an expert evaluation system to fuse information acquired from various data sources. The data sources can correspond to conditions associated with the vehicle as a unit as well as external elements. The expert evaluation system monitors and evaluates the information from the data sources according to a set of rules by converting each data value into a metric value, determining a weight for each metric, assigning the determined weight to the metric, and generating a weighted metric corresponding to each data value. The expert evaluation system compares each weighted metric (or a linear combination of metrics) against one or more thresholds. The results from the comparison provide an estimation of a likelihood of one or more traffic features occurring.

The present invention relates to a method for providing a route stipulation for a route system of a vehicle, comprising the following steps: providing a plurality of detected trajectories of further vehicles in a route section to be used, ascertaining a trajectory stipulation from the detected trajectories, ascertaining a deviation zone from the detected trajectories, wherein the deviation zone is determined on the basis of a deviation of at least individual detected trajectories from the trajectory stipulation, determining the route stipulation at least on the basis of the trajectory stipulation and the deviation zone.

A memory embodies instructions, and a processor is coupled to the memory and is operative by the instructions to facilitate: accessing a source of information regarding farm cultivation techniques; constructing a cultivation knowledge graph by parsing the source of information regarding farm cultivation techniques, using natural language processing; identifying cultivation quality assessment factors by applying machine learning to the cultivation knowledge graph; estimating quality of a farm cultivation task by comparing a stream of real-time data to the cultivation quality assessment factors, wherein the stream of real-time data is related to performance of the farm cultivation task; identifying from the stream of real-time data, using the cultivation knowledge graph, a controllable variable that affects the quality of the farm cultivation task; and improving the quality of the farm cultivation task by facilitating a change in the controllable variable. The controllable variable may be the identity of a tractor operator.

Dynamic throttle pedal filtering of a vehicle is provided. An automated throttle filtering system may be included in the vehicle that may operate to filter throttle pedal input based on detection of a rough driving surface. The rough driving surface detection may be based on an evaluation of wheel speed signals or an indication of traction loss. The throttle pedal input may be filtered corresponding to rough driving surface magnitude values determined based on the wheel speed signals. For example, filtered torque demand values may be determined based on the rough driving surface magnitude values and included in a torque demand request communicated to the vehicle's powertrain system. The resulting torque output may modulate an undesirable oscillating torque demand that may be generated in relation to operation of the vehicle on a rough driving surface.

An apparatus and a method for controlling an engine operating point of a hybrid electric vehicle are provided to determine charging and discharging tendency based on a moving average of an engine torque and a demand torque as well as a dynamical event capture. The method includes detecting a demand torque of a driver and determining a charging and discharging tendency by calculating a moving average based on the demand torque. System efficiency is then reflected using a dynamical event capture and the charging and discharging tendency is leveled. A compensation amount of the operating point is also determined based on the leveling of the charging and discharging tendency and the operating point of the hybrid electric vehicle is adjusted based on the compensation amount of the operating point.

A device for determining a tachometer characteristic curve of a motor vehicle includes a detection apparatus and a determining apparatus. The determining apparatus is configured to form a tachometer characteristic curve on the basis of one or more mean value pairs, which are formed by means of one locomotion signal mean value and one speed mean value, by means of which tachometer characteristic curve locomotion signals and speed values are converted into one another, and/or to change a tachometer characteristic curve which is already present.

A travel information acquisition section acquires travel information including at least a position, speed, and deceleration of the vehicle. An information generation section generates congestion location information indicating a position of a congestion tail based on the travel information. A transmission section transmits the congestion location information generated by the information generation section to another vehicle. The information generation section determines whether or not congestion is occurring at the current position of the vehicle based on an amount of reduction in speed from the maximum speed and the deceleration in a first time period of a specific length, and when determined that congestion is occurring, generates the congestion location information including position information containing the current position of the vehicle itself as information indicating the congestion tail position.

A method for characterizing the curvature of a road section, including: selecting, from among the points of the section, the points marking a curvature of the section; computing, for each selected point of the section contained between the second and the penultimate one, an indicator of curvature of the section at this point; identifying each bend contained in the road section, each bend including a set of successive selected points of the section; and for each bend contained in the road section, comparing the indicator of curvature of at least one of the points of the bend with a predetermined threshold. If the indicator of curvature computed for at least one of the selected points of the bend exceeds the predetermined threshold, recording, in a database, a data record including at least the set of points of the bend, and an item of data characterizing the curvature of the bend.
