Abstract:
A passenger restraint system comprising:a roll angular velocity detecting device configured to detect a roll angular velocity about a longitudinal axis of a vehicle; a roll angle calculating device configured to calculate a roll angle of the vehicle based on the roll angular velocity detected by the roll angular velocity detecting device; a steering angle detecting device configured to detect a steering angle; a passenger restraint device configured to restrain a passenger; and a control unit configured to actuate the passenger restraint device when the roll angular velocity detected by the roll angular velocity detecting device exceeds a prescribed angular velocity and the roll angle calculated by the roll angle calculating device exceeds a first prescribed angle, the control unit being further configured to subtract a prescribed value from the roll angle successively, when the roll angular velocity detected by the roll angular velocity detecting device exceeds the prescribed angular velocity and the steering angle detecting device detects the steering angle to be oriented toward a side of the vehicle in which the vehicle is rolling before calculation of the roll angle by the roll angle calculating device exceeds the first prescribed angle, and the control unit being further configured to reset a determination of whether or not the roll angular velocity is greater than or equal to the prescribed angular velocity and a determination of whether or not the roll angle is greater than or equal to the first prescribed angle, when the roll angle obtained after subtracting falls below a second prescribed angle.
