ROLLOVER PREDICTOR JUDGMENT DEVICE OF COMBINATION VEHICLE AND COMBINATION VEHICLE

摘要

A rollover predictor judgment device (30) for a combination vehicle (1) includes a lateral acceleration sensor (26), a yaw rate sensor (27), an articulate angle sensor (23), and a judgment device in a form of a retarder controller (32). The judgment device judges that the combination vehicle is in a rollover predictor status when a first lateral acceleration calculated based on a detection value of the lateral acceleration sensor (26) is a first threshold or more or when a second lateral acceleration calculated based on a detection value of the yaw rate sensor (27) and a detection value of the articulate angle sensor (23) is a second threshold or more.

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; a steering-angle sensor that is configured to detect a steering 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 steering-angle sensor, wherein the judgment device is configured to judge that the combination vehicle is in the rollover predictor status when the 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 steering-angle sensor is a second threshold or more.
