Abstract: A method of updating navigational map data with missed attributes via polyline geometry matching includes obtaining first and second navigational map data sets. Chains are built of original road elements of the first navigational map data and chains are built of original road elements of the second navigational map data set. A spatial index of the chains is created. A set of chain candidates that are within a predetermined distance of each other is created according to the spatial index. The size of the set of chain candidates is reduced utilizing an angle filter. Each remaining chain candidate of the reduced set of chain candidates is ranked and the chain candidate having a best ranking is selected as the best candidate chain. The first navigational map data set is updated utilizing attributes from the best candidate chain.

Abstract: A navigation apparatus and a method for updating map data thereof are provided. A map database of the navigation apparatus stores data of a plurality of existed roads. When coordinates of the navigation apparatus are not located on any one of the existed roads, a comparison module of the navigation apparatus determines whether the shortest distance between the coordinates and the existed roads exceeds a predetermined threshold. If the shortest distance exceeds the predetermined threshold, a map data adding module updates a traveling path according to a plurality of succeeding coordinates of the navigation apparatus until the navigation apparatus is determined to return on one of the existed roads. When the map data adding module finishes updating the traveling path, the map data adding module stores data of the traveling path in the map database of the navigation apparatus.

Abstract: A voltage at an output end of a switch of an electric vehicle supply equipment is detected before charging an electric vehicle. An earth leakage circuit breaker is tripped for cutting off power inputted to the switch and preventing the output end from outputting the power when the voltage is higher than a first predetermined value. The switch is turned on for outputting the power from the output end to charge the electric vehicle when the voltage is lower than the first predetermined value. A current is detected at the output end. Power inputted to the switch is cut off for preventing the output end from outputting the power when the current is higher than a second predetermined value.
