Title: Method for deciding parking status
Inventor: ODA TOSHIHIKO
IPC: G05B13/02
Filed: 1989-12-28
Abstract: PURPOSE:To more surely decide parking status by adopting fuzzy inference integrating the subjective and experimental rules of a parking zone operator for the calculation processing of parking status and a change based upon the number of IN/OUT behicles per unit time obtained from vehicle sensors arranged on an inlet and an outlet. CONSTITUTION:The occupation ratio of the parking zone and the change ratio of the number of parked vehicles are calculated from IN/OUT vehicle number information per unit time obtained from the vehicle sensors arranged on the inlet and outlet of the parking zone and the parking capacity of vehicles and a parking index and a change index are calculated from the shown membership functions in respective grades. The parking index status (i) is divided into three grades, i.e. high '1', medium '2' and low '3', and the change index status (j) is divided into three grades, i.e. increment '1', no change '2' and decrement '3'. Both the status (i), (j) are used as the antecedent part of IF to THEN formats and the parking status (full, confused, available, no parking) is allocated to the consequent part. Consequently, the parking status can be more surely decided by using the membership functions mixing the subjective and experimental rules of a parking zone operator.
