Title: Guidance error warning method
Inventor: FUJIMOTO EISUKE
IPC: G08G1/16
Filed: 1988-01-22
Abstract: PURPOSE:To prevent an accident previously by predicting an end point error at the time of terminating a follow-up drive during the follow-up drive and issuing a warning when the end point error exceeds a maximum allowable value. CONSTITUTION:Each time a distance pulse is generated from a distance sensor 15, a processor 11 calculates a handle correcting rotation quantity which is the difference between a basic handle rotation angle stored in a memory 12 and an actual handle rotation angle read from a handle sensor 14. The handle correcting rotation quantity is accumulated in accordance with a follow-up drive traveling, by using the accumulated quantity, a weighting calculation in accordance with the present traveling position is executed and the error (end point error) at the end point is obtained. When the end point error exceeds the maximum allowable value set beforehand, a driver is warned to do the follow-up drive traveling again by a display device 19 even during the follow-up drive. Thus, since the warning is given during the follow-up drive, the accident can be prevented previously.
