Abstract
A method of generating a horizon for use by an ADAS of a vehicle involves using historical vehicle probe data to determine the likelihood that different outgoing paths are taken at a decision point along a currently traversed road segment, and deriving a probability that each path may be taken. The probability is based on historical paths taken by vehicles at the decision point as indicated by the vehicle probe data.
Claims15
A computer implemented method of generating a horizon for use in an ADAS of a vehicle, comprising:
- generating the horizon using positional data relating to the movement of devices associated with vehicles with respect to time.
An apparatus for generating a horizon for use in an ADAS of a vehicle, comprising:
- a memory storing a probability matrix having, in respect of each of one or more decision points of a road network, data indicative of the relative probability that each of a plurality of possible outgoing paths at the decision point will be taken by a vehicle for each of one or more possible incoming paths, wherein the data indicative of the relative probability that a given possible outgoing path will be taken is based upon positional data relating to the movements of a plurality of devices associated with vehicles with respect to time;
- and
- at least one processor arranged to use the probability matrix to determine data indicative of the relative probability that each of a plurality of possible outgoing paths associated with a decision point will be taken by the vehicle in the immediate future, and to generate the horizon from the determined data.
