ACTIVE STEERING SYSTEM FOR ARTICULATED BUS

摘要

The active steering system for an articulated articulated bus is provided. In the auxiliary hydraulic turntable steering mode, the steering assist function of the joints articulated buses. When the joint is articulated buses will travel in a straight line at high speed lane changes or perform work, the auxiliary steering mode can provide a stable driving performance. In the secondary steering mode, the better the steering locus is formed when the cornering action of the joint-connecting bus to perform. Gathering information about the location of the transmission word, the position of the steering wheel, a running speed the steering load given to the front frame and the trailer frame is calculated. Further, if judged to be the control unit the optimum angle of the hydraulic turntable, the restraining load is generated in order to ensure an optimum angle of the joint-connecting bus. The auxiliary steering mode also supports a reverse operation of the joint-connecting bus. When the joint-connecting joint is adjusted to the optimum orbit the joint-connecting bus is backward to the target position.
