Abstract: The invention obtains a processing unit and a processing method capable of improving a rider's safety. The invention also obtains a collision warning system that includes the processing unit. The invention further obtains a motorcycle that includes the collision warning system. A processing unit (20) includes: an acquisition section (21) that acquires environment information corresponding to output of an environment detector (11); a determination section (22) that determines presence or absence of a possibility of a collision on the basis of the environment information; and a control section (23) that makes a warning device (30) output a warning in the case where the determination section (22) determines that there is the possibility of the collision. During travel of the motorcycle, the acquisition section (21) acquires posture information related to a bank angle of the motorcycle, and the control section (23) changes the warning output by the warning device (30) in accordance with the posture information.

Abstract: The present invention obtains an assistance system capable of assisting with function setting of a straddle-type vehicle by a rider, a portable wireless terminal used for such an assistance system, a control method for such an assistance system, a control method for such a portable wireless terminal, and a program run on such a portable wireless terminal. In an assistance system (1), an acquisition section (51) of a portable wireless terminal (50) wirelessly acquires information on the function setting operated on an input device (11) of a straddle-type vehicle (10), and an input section (52) of the portable wireless terminal (50) provides a guidance corresponding to the information on the function setting operated on the input device (11) of the straddle-type vehicle (10) when accepting the operation of the function setting by the rider.

Abstract: A processing unit includes: an acquisition section that acquires forward environment information corresponding to output of a forward environment detector; a recognition section that recognizes the target on the basis of the forward environment information; and a control section that controls the forward environment detector. During travel of the motorcycle, the acquisition section acquires posture information related to a bank angle of the motorcycle, and the control section changes a detection angle range for forward detection of the motorcycle by the forward environment detector in accordance with the posture information.
