Claim:
1. A rollover predictor judgment device for a combination vehicle comprising a front vehicle body and a rear vehicle body swingably connected to the front vehicle body, the rollover predictor judgment device comprising: a lateral acceleration sensor that is configured to detect an acceleration of the rear vehicle body in a right-left direction; a yaw rate sensor that is configured to detect a yaw rate of the rear vehicle body; an articulate angle sensor that is configured to detect an articulate angle of the front vehicle body with respect to the rear vehicle body; and a judgment device that is configured to judge whether or not the combination vehicle is in a rollover predictor status based on a detection data detected by the lateral acceleration sensor, the yaw rate sensor and the articulate angle sensor; and a notifying device that is configured to notify that the combination vehicle is in a rollover predictor status when the rollover predictor judgment device judges that the combination vehicle is in the rollover predictor status, wherein the judgment device is configured to judge that the combination vehicle is in the rollover predictor status when a first lateral acceleration calculated based on a detection value of the lateral acceleration sensor is a first threshold or more, or when a second lateral acceleration calculated based on a detection value of the yaw rate sensor and a detection value of the articulate angle sensor is a second threshold or more, and the judgment device is configured to output a notification signal to the notifying device to notify that the combination vehicle is in the rollover predictor status and, subsequently, configured to stop outputting the notification signal when a status judged not to be in the rollover predictor status continued for a predetermined period.
