Title: Automobile
Inventor: HONEY STANLEY K
IPC: G01C21/30
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To achieve a highly accurate calibration of sensors by omitting the calibration of a bearing sensor while the direction of own car is altered to perform a calibration of a distance sensor when the charging of the direction is finished. SOLUTION: While the direction of a vehicle V is altered, decision is made by a traditionally described method and hence, the subroutine left of algorithm is bypassed to omit recalibration of sensor means 16 and 26 at this time. If the altering of the direction of the vehicle V fails, the recalibration of the bearing sensor means 26 is accomplished. Next, not at the timing when the vehicle V has just changed its direction, the subroutine left is bypassed. If the vehicle V just has changed its direction, the distance sensor means 16 is recalculated. Thus, a computer 12 accomplishes a proper correction of a bearing deviation list according to a specified output of the bearing means 26 to correct a corresponding calibration coefficient stored in a medium 14. As a result, an advancing is made accurately from the old estimated position DRPo to the current estimated position DRPc.
