Abstract:
1. A rollover determination system comprising: a first roll rate sensor that detects a first roll rate of a vehicle; a second roll rate sensor that detects a second roll rate of the vehicle; a lateral acceleration sensor that detects a lateral acceleration of the vehicle in a lateral direction of the vehicle; and a controller that makes a first determination whether there is a possibility of rollover of the vehicle on the basis of at least one of the first roll rate detected by the first roll rate sensor and the second roll rate detected by the second roll rate sensor together with the lateral acceleration detected by the lateral acceleration sensor, wherein the first roll rate sensor and the second roll rate sensor are arranged to detect a rotational angular velocity about a longitudinal axis of the vehicle, and the controller makes, in parallel to the first determination, a second determination whether there is a possibility of rollover of the vehicle on the basis of one of the first roll rate and the second roll rate.
