The invention obtains a straddle-type vehicle information processor and a straddle-type vehicle information processing method capable of recognizing that a traveling straddle-type vehicle enters a falling phase with a high degree of accuracy at appropriate timing and thereby contributes to improvement in occupant safety. A straddle-type vehicle information processor 10 includes: a posture information acquisition section 11 that at least acquires a roll rate Rr and a yaw rate Ry generated in a traveling straddle-type vehicle 1 as posture information; and a falling phase recognition section 12 that recognizes that the straddle-type vehicle 1 enters a falling phase in the case where a change in a degree of instability over time, which is derived at least on the basis of the roll rate Rr and the yaw rate Ry, shows an increasing tendency.
