Abstract

The invention discloses a BEV driving range estimation device based on remote data transmission. The device comprises a vehicular navigator, a control unit module, a GPRS communication module, a SOC computation module, and an information center. The vehicle navigator performs GPS positioning on a vehicle to acquire location information of the vehicle. A driver enters a destination into the vehicular navigator which sets a driving line. The control unit module stores vehicle information, including vehicle type, vehicle parameters and motor parameters. The control unit module divides the driving line set by the vehicular navigator into a plurality of segments and transmits a signal of extracting reference kinematic fragments to the information center through the GPRS communication module. The control unit module receives the reference kinematic fragments, then computes power consumption delta C of driving on the segments, and outputs the data to the SOC computing module which estimates current driving range of the vehicle, and an estimated value of the driving range is displayed on a display.

Description

technical field [0001] The invention relates to a device and method for estimating the mileage of a pure electric vehicle based on remote data transmission, and belongs to the technical field of remote data transmission. Background technique [0002] With the continuous development of vehicle technology and key parts technology, various electronic systems and equipment on vehicles are becoming more and more complete and more and more humanized. [0003] The penetration rate of domestic automobiles is increasing year by year, and people's understanding of automobiles is getting deeper and deeper. Therefore, when buying a car, people not only pay attention to the mechanical properties of the car itself, but also pay attention to various electronic systems and equipment related to the car. [0004] Since the 1980s, foreign automobile manufacturers have equipped their vehicles with multifunctional control / diagnostic systems, which can warn drivers when the vehicle fails. With t...
