<P>PROBLEM TO BE SOLVED: To provide a recommended driving operation presentation device for a vehicle which can reduce an operation amount for future action prediction and flexibly adapt itself to increasing or decreasing traffic participants in the prediction, and presents recommended driving operation to a driver of an own vehicle based on an action predicted result. <P>SOLUTION: A symbolizing part 40 symbolizes respective pieces of information constituting a driving scene to describe the whole driving scene in which an own vehicle is placed. Consequently, even when, for example, traffic participants increase or decrease in number, the pieces of information which are symbolized merely increase or decrease, so the increasing or decreasing traffic participants can be flexibly dealt with. Further, a symbol transition prediction part 60 predicts how a symbolized driving scene changes using Influence of actions of the own vehicle on actions of the traffic participants which is estimated based upon change in state of the respective traffic participants including the own vehicle. Therefore, when change in driving scene is predicted, prediction precision can be improved while the operation amount is greatly reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
