A transmission ratio control device at the inflection section utilizing map information and its method of operation

摘要

The present invention relates to one kind to utilize cartographic information and operating method in inflection portions for controlling variator ratio. More specifically, the present invention relates to one kind to utilize cartographic information and its operating method in inflection portions for controlling variator ratio, it, which can most effectively drive a vehicle, passes through inflection point, inflection point is before identifying vehicle, the inflection point is used before changing Vehicular shift ratio using the navigation routine Boot Server of high-precision map, the inflection point of inflection point information identification, vehicle, and vehicle balance information. The device includes: that Inflexion extracting portion generates inflection point, and the corresponding information of the inflection point sends the route guidance server that auto-navigation device uses map datum by establishing road; Vehicle balance measurement part is to determine vehicle balance vehicle at least one number of passengers or amount of load goods vehicle by measure according to the weight; Speed Control portion converts the inflection point of gear, according to car speed. ;The 2015 of copyright KIPO submissions
