PROBLEM TO BE SOLVED: To prevent a rollover determinig device from being operated, even when switching-off of an ignition and removal of a signal wire are forgotten. SOLUTION: An ECU judges the presence or absence of traveling signal and collision detection signal (S2) when a power source is turned on (S1). When the ECU judges that both of the traveling signal and the collision detection signal are not inputted (S2 "absence"), the ECU inhibits the decision of rollover (S3) and repeats the processing of S2. The ECU judges the presence or absence of a roll rate signal (S4) when the ECU judges the input of at least one of the traveling signal and the collision detection signal (S2 "presence"). In the case of the presence of the roll rate signal (S4 "presence"), an occupant crash protection device is deployed (S5). When the roll rate signal is not inputted (S4 "absence"), processing of S2 to S4 is repeated. COPYRIGHT: (C)2006,JPO&NCIPI
