Abstract
Angular velocity in a rolling action of a vehicle is detected by an angular velocity sensor, and a difference between two angular velocities detected in a short time interval is calculated. The calculated angular velocity difference is compared with a predetermined threshold value. If the angular velocity difference is larger than the threshold value, a passenger-protecting device is activated. A rolling angle of the vehicle may be calculated by integrating the detected angular velocity, and a combination of the rolling angle and the angular velocity may be compared with a predetermined threshold. If the combination exceeds the threshold, it is determined that the vehicle is rolling over and the passenger-protecting device is activated.
