Passenger protection apparatus
First Claim
1. A passenger protection apparatus, comprising:
- a rollover angular speed detection device, which detects a rollover angular speed during vehicle rollover;
a rollover determination device, which conducts a determination of the vehicle rollover based on the rollover angular speed detected by the rollover angular speed detection device and a rollover angle obtained from the rollover angular speed;
a passenger protector, which operates in accordance with a determination result of the rollover determination device to protect a passenger;
a vertical G sensor, which detects an acceleration of an up and down direction of the vehicle;
a horizontal G sensor, which detects an acceleration of a right and left direction of the vehicle; and
an angular speed sensor error determination device, which conducts a determination whether or not a zero-point drift of the rollover angular speed detection device occurs based on a detected signal of the vertical G sensor or the horizontal G sensor.
