1. A rider-assistance system (1) of a straddle-type vehicle (100), the rider-assistance system comprising:
a processor (20) configured to:
acquire surrounding environment information about the straddle-type vehicle (100);
determine a necessity of assistance operation executed by the rider-assistance system (1) to assist with a rider's operation on the basis of the surrounding environment information; and
control an execution device (P) to execute the assistance operation in response to determining that the assistance operation is necessary, wherein
the surrounding environment information includes information on surrounding environment behind the straddle-type vehicle (100),
the surrounding environment information is information corresponding to output of a sensor provided to the straddle-type vehicle (100),
determining that the assistance operation is necessary in a case where at least a first condition and a second condition are simultaneously satisfied,
the first condition is a determination that, on a basis of a comparison between a collision index value (I) and a first reference value, a collision possibility of the following vehicle against the straddle-type vehicle (100) is higher than a first determination criterion,
the collision index value (I) is an index value depending on the information on the surrounding environment at the rear and is an index value of the collision possibility of a following vehicle against the traveling straddle-type vehicle (100),
the second condition is a determination that, on the basis of a comparison between a stability index value (J) and a second reference value, the following vehicle travels at a lower relative speed (Vr) than a second determination criterion to the straddle-type vehicle (100),
the stability index value (J) is an index value depending on the information on the surrounding environment at the rear and is an index value of a stability degree of a relative distance (Dr) of the following vehicle to the traveling straddle-type vehicle (100).
