Abstract: An anti-jackknife steering system for an articulated bus is provided. A hydraulic turntable is used for actively generating a calculated force to balance the inertia of a front frame and a trailer frame.

Consequently, while the articulated bus is driven on a slippery road, the possibility of causing collision is minimized.

Abstract: An active steering system for an articulated bus is provided. In an assisted steering mode, a hydraulic turntable assists in the steering action of the articulated bus. While the articulated bus is linearly driven at a high speed or the lane-changing action is performed, the assisted steering mode can provide stable driving performance. In the assisted steering mode, a better steering trajectory is achieved while a cornering action of the articulated bus is performed. By collecting the information about the driving velocity, the position of the transmission gear and the position of the steering wheel, a steering force applied to the front frame and the trailer frame is calculated. Moreover, if the control unit judges that the angle of the hydraulic turntable is optimal, a locking force is generated to assure the optimal angle of the articulated bus. The assisted steering mode also supports the action of reversing the articulated bus.

Consequently, the problem of losing power or generating electric arc in the battery box will be avoided.
