    Abstract: A mobile body capable of improving the accuracy of collision judgment. The mobile body including a fuel cell system has a first sensor which detects a physical quantity concerning the moving state of the mobile body, a second sensor which detects a physical quantity concerning the operation state of the fuel cell system, and a judgment section which receives detection signals from the first and second sensors to judge the presence of the collision of the mobile body based on the two detection signals. The judgment section can change a threshold value 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 collision of the mobile body. The first sensor can be constituted of an acceleration sensor, and the second sensor can be constituted of a gas pressure sensor or the like.

    Abstract: PROBLEM TO BE SOLVED: To provide a startup device for an occupant protecting device, preventing erroneous startup of the occupant protecting device with simplification in structure, and an acceleration sensor module used for such a device. SOLUTION: The acceleration sensor module 10 includes chips 11a and 11b, a first determining section 12, a second determining section 13 and an OR-circuit 14 for enabling the detection of accelerations of different detecting shafts. This allows the startup device 1 to use the chips 11a and 11b of the acceleration sensor module 10 as redundancy sensors. Thus, no need arises for the startup device 1 to have an acceleration sensor and a microcomputer for ensuring redundancy, resulting in simplification of the startup device 1 in structure. Further, controlling a first switching portion 50 based on an output of the acceleration sensor module 10 and an output of the microcomputer 40 prevents the occupant protection device from erroneous startup merely with the output of the microcomputer 40.
