MOBILE BODY

摘要

This invention is related to a mobile body (5) capable of improving the a ccuracy of collision judgment. The mobile body including a fuel cell system (1) has a first sensor (101) which detects a physical quantity concerning th e moving state of the mobile body (5), a second sensor which detects a physi cal quantity concerning the operation state of the fuel cell system, and a j udgment section which receives detection signals from the first and second s ensors to judge the presence of the collision of the mobile body (5) based o n the two detection signals. The judgment section can change a threshold val ue to be compared with the detected value of the first sensor in accordance with the detected value of the second sensor, to judge the presence of the c ollision of the mobile body. The first sensor can be constituted of an accel eration sensor, and the second sensor can be constituted of a gas pressure s ensor or the like.
