Abstract:
The present invention relates to a method for controlling the driving of a vehicle, which vehicle can be run in at least one mode focused on operability and at least one mode focused on economical operation and can be switched between said modes, comprising the steps of determining (S1 ) a torque offtake pattern continuously over a given period of time (t 1 - t 2 ), of determining (S2) the proportion (Q) of said period during which the vehicle runs with a torque offtake which is either above a predetermined value (M max ) or below a predetermined value (M min ), and of using said proportion as a basis for deciding (S3) whether the current mode is the most appropriate. The present invention also relates to a system for controlling the driving of a vehicle. The present invention relates also to a motor vehicle. The present invention also relates to a computer programme and a computer programme product.
Abstract:
A context-based driver scoring system evaluates various aspects of driving and parking behavior while taking into account context-related conditions. The inputs to the system may include driving data, the conditions specifying the current context, and the configuration parameters data. The outputs of the system may be driving scores that characterize the performance of the driver according to the given context. In particular, first the context module is used to calculate a context factor that enables applying the effect of the context conditions to the driving scores.
Abstract:
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.

Abstract:
The present invention relates to a method and a system for estimating a weight m v for a vehicle on the basis of - at least two forces which act upon the vehicle, comprising a motive force F T and at least one further force, and - topographical information for a relevant section of road. According to the present invention, estimation is performed when said at least two forces are dominated by said motive force F T.

Ferner betrifft die Erfindung ein Computerprogrammprodukt, welches ausgebildet ist ein erfindungsgemäßes Verfahren durchzuführen; eine Recheneinheit oder eine Verarbeitungseinrichtung, bevorzugt ein Steuergerät oder eine Steuereinrichtung für ein Fahrzeug; und eine Sicherheitseinrichtung oder ein Sicherheitssystem für ein Fahrzeug, insbesondere ein Fahrerassistenzsystem für ein Kraftfahrzeug.
Abstract:
A tilt sensor (11) and method comprises a first accelerometer (10) for measuring a first acceleration level associated with a first axis of the vehicle, A second accelerometer (12) measures a second acceleration level associated with a second axis of the vehicle that is generally perpendicular to the first axis. A data processor (30) is capable of determining an arcsine-derived tilt based on an arcsine equation and the determined first acceleration level The data processor (30) is capable of determining an arc-cosine-derived tilt based on an arccosine equation and the determined second acceleration level. The data processor (30) comprises a selector (e.g., 24) for selecting the arcsine-derived tilt as the final tilt of the vehicle if the determined arcsine-derived tilt is lesser than the determined arccosine derived tilt such that the final tilt compensates for vertical acceleration associated with changes in the terrain In the direction of travel of the vehicle.
Abstract:
The invention relates to an assessment method for assessing acceleration behaviour of a driver of a vehicle. The method comprises determining the vehicles acceleration a, calculating one or more threshold values for its acceleration which depend on at least one situation-specific parameter, comparing its acceleration a with said one or more threshold values, and generating on the basis of the comparison a grading signal related to said calculated one or more threshold values. The invention relates also to an assessment system for assessing acceleration behaviour of a driver of a vehicle.
