Abstract

A vehicle behavior estimation device includes: a storage unit configured to store a restriction condition at a point of a vehicle for which behavior is estimated; vehicle state data that includes position information and speed information of the vehicle; behavior parameters that include speed information and acceleration information of the vehicle; and physical restriction conditions that include an upper limit and a lower limit of the acceleration information; and a processor configured to obtain the vehicle state data by using the restriction condition at the point; calculate behavior parameters of a vehicle model that satisfy a physical restriction condition from the vehicle state data and the restriction condition at the point; update the vehicle state data of the vehicle model based on the behavior parameters; and repeat processing to calculate behavior parameters by using the updated vehicle state data and to update the vehicle state data.

First claim

What is claimed is:

1. A vehicle behavior estimation device comprising:
a memory configured to store:
a first restriction condition at a first point, the first restriction condition including a position, a time, and a speed at the first point of a vehicle;
a second restriction condition at a second point different from the first point, the second restriction condition including a position, a time and a speed at the second point of the vehicle; and physical restriction condition…
