MODE AND ARRANGEMENT FOR CONTROLLING OF A ROAD-CROSSING IN A NAVIGATIONAL SYSTEM Russian patent published in 2006 - IPC G01C21/34 

FIELD: refers to navigational technique.

SUBSTANCE: the mode for controlling of a road-crossing includes checking-up of the scheme of the road-crossing for forming of the prescribed road-crossing on the basis of information about the position of the carrier. Besides, forming of turning lead switch liable for image on the road-crossing is envisaged and simultaneous reflection of the road-crossing and turning lead switch generated on it. The arrangement for controlling a carrier on the road-crossing includes an arrangement for checking up the scheme on the road-crossing, an arrangement for forming of a turning lead switch and an arrangement for simultaneous reflection of the road-crossing and the turning lead switch. The navigational system has a device for storage of data necessary for forming road-crossing, a device for storage of basic switch data, a memory storage for keeping coordinates of the switch for indicating the direction and tables of trigonometry functions and also a central processor for controlling on the road-crossing with the aid of turning lead switch at using data necessary for forming road-crossing, basic switch data and tables of trigonometry functions and a device for reflection of the road-crossing with turning lead switch.

EFFECT: allows quickly and effectively to form a switch at approaching of a carrier to an access road.
