Travel trace generation method and travel trace generation device
First Claim
1. A running locus generating method comprising:
- deriving, by an electronic control unit, a running locus by a convergent computation according to an optimizing technique to achieve a first constraint condition based on a predetermined target passing time and a road boundary; and
deriving, by the electronic control unit, a running locus from derived running loci that run within a street boundary and pass within the predetermined target passing time for reaching a destination by a convergent computation of an evaluation function according to the optimizing technique that gives preference to a predetermined driving condition,wherein the evaluation function evaluates predetermined driving conditions other than target passing time.

Abstract
A first convergent computation section 25 for deriving a running locus by a convergent computation such as to achieve a first constraint condition based on a target passing time ts and a road boundary of a road D and a running locus deriving section 26 for deriving a running locus by a convergent computation of an evaluation function J3 for preferring a predetermined driving condition in a state achieving the first constraint condition are provided, a running locus is convergently computed such as to satisfy the first constraint condition set according to the target passing time ts and the road boundary of the road D, and a running locus is derived by convergently computing an evaluation function J3 for preferring a predetermined driving condition in a state satisfying the first constraint condition.
