With such a configuration, it is possible for the rider to be prepared for sudden activation of the protection device P in the state where no collision has occurred, and the safety of the rider is further improved.

Although the embodiments have been described above, the present invention is not limited to the description of the embodiments. That is, the present invention includes a modified form of the embodiment described above. For example, only a part of the embodiment may be implemented, or a part of the embodiment may be modified.

For example, in the above, the vehicle running behind the saddle riding type vehicle 100 is recognized using the surrounding environment detecting device 11 that detects the surrounding environment behind the saddle riding type vehicle 100, and the possibility of collision by the vehicle is determined. Although the case has been described, a vehicle and a saddle riding type vehicle that travel behind the saddle riding type vehicle 100 by using the ambient environment detecting device 11 that detects the surrounding environment on the side in addition to the rear side of the saddle riding type vehicle 100. Vehicles traveling on the side of the vehicle 100 may be recognized, and the possibility of collision by these vehicles may be determined. In that case, in addition to the backward index value I, the lateral index value I may be derived. The side index value I is an index value that depends on the information on the surrounding environment on the side, and is an index value of the possibility of collision of the vehicle traveling on the side of the saddle riding type vehicle 100 with the saddle riding type vehicle 100. Is defined as The lateral index value I may be the reciprocal of the relative distance Dr of the vehicle to the saddle riding type vehicle 100, or may be the relative speed Vr of the vehicle to the saddle riding type vehicle 100, and the saddle.

For example, the lateral index value I is defined by the same formula as the backward index value I. The larger the lateral index value I, the higher the possibility of collision.

Further, for example, the case where the surrounding environment detection device 11 is provided in the saddle riding type vehicle 100 has been described above, but the surrounding environment detection device 11 is provided in a vehicle different from the saddle riding type vehicle 100. Good. That is, the acquisition unit 21 may acquire the surrounding environment information through the inter-vehicle communication. In particular, it is preferable that the surrounding environment detection device 11 is provided in a vehicle that is determined to have a high possibility of collision.

Further, for example, at least one of the determination standard for determining the rearward index value I and the determination standard for determining the lateral index value I may be settable by the rider.
