ABSTRACT:
A compensated vehicle heading system wherein magnetic heading information is combined with heading information determined by sensing vehicle dynamic movement to provide augmented heading information is disclosed. The magnetic heading information is provided by a magnetic heading sensor. The heading information determined by sensing vehicle dynamic movement is provided by a vehicle dynamic system that senses vehicle direction changes. In one form, the vehicle dynamic system includes magnetic sensors mounted so as to sense the speed of rotation of the undriven wheels of a land vehicle and generate pulse chains in accordance therewith. These pulse chains are scaled and applied to an UP/DN counter. The output of the UP/DN counter is continuously compared with the magnetic heading information and the results of the comparisons control the gating of a trickle pulse addition to the scaled pulse chains applied to the UP/DN counter. The thusly controlled output of the UP/DN counter is the augmented heading information. The trickle pulses are created by dividing the pulse chain related to one of the undriven wheels by a predetermined factor. In addition, the UP/DN counter is set to the magnetic heading state when the system is initially activated. Further, errors are prevented by interconnecting the pulse chains such that no more than one pulse can be gated to the UP/DN counter from a particular wheel when the other wheel stops producing pulses.
