Vehicle overturn preventing device

摘要

A vehicle overturn prevention device includes a first flywheel disposed in a front portion of a trailer of a combination vehicle, and a second flywheel disposed in a rear portion of the trailer. Each of the first and second flywheels is mounted on the vehicle through a double-gimbal support mechanism. When the combination vehicle makes a left turn (YES in step S3), a second gimbal shaft of the first flywheel that is orthogonal to the front-back direction of the combination vehicle is restrained, but a fourth gimbal shaft of the second flywheel that is orthogonal to the front-back direction of the combination vehicle is released (step S4). When the combination vehicle makes a right turn (NO in step S3), the fourth gimbal shaft of the second flywheel is restrained, but the second gimbal shaft of the first flywheel is released (step S7).
