VEHICLE BEHAVIOR ESTIMATION METHOD, VEHICLE CONTROL METHOD, AND VEHICLE BEHAVIOR ESTIMATION DEVICE

A vehicle behavior estimation method including: detecting a speed of a first preceding vehicle (3) traveling in front of a host vehicle (1) in a first lane (2a) where the host vehicle (1) is traveling; detecting a speed of an adjacent vehicle (4) traveling in a second lane (2b) adjacent to the first...

Beschreibung
Zusammenfassung:	A vehicle behavior estimation method including: detecting a speed of a first preceding vehicle (3) traveling in front of a host vehicle (1) in a first lane (2a) where the host vehicle (1) is traveling; detecting a speed of an adjacent vehicle (4) traveling in a second lane (2b) adjacent to the first lane (2a); calculating a relative speed between the first preceding vehicle (3) and the adjacent vehicle (4); predicting whether or not an absolute value (vr1) of the relative speed will be at or below a speed threshold value (Tv) within a predetermined time (T0) from a point time when a decrease in the absolute value (vr1) of the relative speed starts to be detected; and estimating that the adjacent vehicle (4) is likely to change lanes into the first lane (2a) when the absolute value (vr1) of the relative speed is predicted to be at or below the speed threshold value (Tv) within the predetermined time (T0) .
