Patent ID: 8847786

Claim:
A driving scene transition prediction device comprising: means for obtaining information regarding lane environment of a lane on which an own motor vehicle drives; means for detecting traffic participants around the own motor vehicle; means for symbolizing information regarding a drive environment or a lane environment, information regarding own motor vehicle and information regarding the traffic participants which form a driving scene of the own motor vehicle, and for describing the driving scene of the own motor vehicle by using the symbolized information; means for estimating interaction, as influence, between the traffic participants on the basis of a state change of each of the traffic participants including the own motor vehicle; means for predicting a transition of the symbolized driving scene symbolized by the symbolizing means for each of a plurality of candidates selectable by the own motor vehicle on the basis of the influence estimated by the estimating means; wherein a recommended driving operation display device; and means for determining a recommended driving operation on the basis of the prediction results obtained by the predicting means in the driving scene transition prediction device, and for displaying the recommended driving operation to a driver of the own motor vehicle on the recommended driving operation device; wherein the determining means generates a plurality of typical driving scenes and an evaluation value of each of the typical driving scenes, calculates an evaluation value of a transition result of a predicted driving scene on the basis of a degree of similarity between the transition result of the predicted driving scene and the typical driving scenes, and determines the recommended driving operation on the basis of the calculated evaluation result of the transition result of the predicted driving scene; and the predicting means repeatedly executes a series of steps including: determining a plurality of operations as operation candidates of the own motor vehicle selectable by the driver of the own motor vehicle; predicting a transition result of the driving scene when each of the determined operations as the operation candidates is executed; and predicting a transition result of the driving scene when a plurality of operations selectable by the own motor vehicle is executed within the transition result of the predicted driving scene, wherein when the predicting means predicts the transition of the driving scene in each of the above series, the determining means calculates an evaluation value of the predicted driving scene finally obtained, calculates a mean value of the evaluation values of the predicted driving scenes after the execution of the operations of the series, and determines the recommended driving operation according to the operations having the maximum mean value.
