发明名称 METHOD FOR IMPROVING THE RELIABILITY OF SPEED LIMIT INFORMATION FOR ON-BOARD SYSTEMS
摘要 A method for assessing the quality of the information contained in a database of a remote server storing the speed limit values of various segments of which a road network is composed, in which the speeds in these segments of vehicles having geolocation devices and devices for communicating with the distant server are recorded in a speed database. The server management system takes into account the speed database in order to select the vehicles which, over a predetermined period of time, have travelled at least one predetermined segment; determines the average maximum speed of travel of said vehicles in the segment over the period of time; compares this average maximum speed with the limit value recorded in an authorized speed limit database; assesses the value of the difference between these two values and, if this difference exceeds a given threshold, triggers a monitoring procedure to monitor the segment concerned. Also discloses is an interface device for implementing this method.
