Embodiment Construction

[0036] Hereinafter, embodiments of the driving assistance system according to the present invention will be described in detail with reference to the accompanying drawings.

[0037] figure 1 is an overall configuration diagram showing one embodiment of the driving assistance system according to the present invention. exist figure 1 Among them, the driving assistance system 1 of the embodiment of the present invention is to generate a driving plan (trajectory) for a vehicle in an arbitrary section (in this case, a turn) of a road on which the vehicle travels and provides support for the driving of the vehicle.

[0038] The driving assistance system 1 has a road information acquisition unit 2 , a condition setting unit 3 , a driving plan generation unit 4 , and a storage unit 5 . The road information acquisition section 2 acquires information on the shape and the like of a road on which the vehicle will travel. The road information acquiring section 2 acquires information on ...

Abstract

A drive assist system includes: an acceleration change pattern setting portion that sets an acceleration change pattern of a vehicle that is a pattern of change in acceleration of the vehicle that occurs while the vehicle travels on a road; and a drive plan generating portion that generates a drive plan for the vehicle based on the acceleration change pattern set by the acceleration change pattern setting portion. The drive assist system generates a drive plan satisfying three conditions, namely, a kinetic model of the vehicle, a passing point of each corner, and an acceleration change pattern, using a solution to two-point boundary-value problems.

Description

technical field [0001] The invention relates to a driving assistance system and a driving assistance method for helping a driver to drive a vehicle. Background technique [0002] There are existing driver assistance systems available that generate a driving plan for making the vehicle turn the fastest by using an optimization method, for example in Theoretical Studies on Minimum-time Cornering Method, Transactions of Society of Automotive Engineers of Japan , Vol.23No.2, described in April1992. [0003] However, in the related art described above, some drivers feel that the comfort is low or it is difficult to drive. Also, it is understood that drivers with poor driving skills may have difficulty responding. As a result, there is a possibility that appropriate driving assistance will not be provided. Contents of the invention [0004] The present invention provides a driving assistance system and a driving assistance method, which can generate an appropriate driving pla...
