Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0010] To achieve accurate estimation of the remaining cruising range of networked electric vehicles, a networked vehicle big data acquisition and processing system is required. The system is able to collect a variety of relevant data under various architectures from numerous sources; then collate and analyze it, and combine it in the cruising range estimation. For the main structure diagram, see figure 1 .

[0011] The system mainly includes: vehicle sensors, GPS positioning system, road information perception system, cloud data receiving system, data transmission processing system and online computing system. The vehicle-mounted sensors, such as battery sensor (IBS), motor temperature and speed sensor, etc., are installed in the corresponding position of the vehicle to obtain real-time information of the vehicle; the GPS positioning system combines ...

Abstract

The invention provides a big data acquisition and processing system and an electric vehicle endurance estimation method based on the same; the system includes a vehicle-mounted sensor, a GPS positioning system, a road information perception system, a cloud data receiving system, a data transmission processing system and an online computing system. Real-time road, traffic, weather and other information are obtained from a cloud server, and then a future driving state of an electric vehicle is forecasted based on the data. According to the vehicle real-time data under an actual driving state, a vehicle dynamic model and a battery model obtained from calculation are more accurate than a traditional vehicle dynamic model obtained based on a physical equation in an electric vehicle driving process. The estimation method can improve the estimation accuracy of the remaining endurance mileage of the networking pure electric vehicle to a great extent. In addition, according to the real-time data obtained from the cloud, a vehicle use strategy is better planned, and the control strategy of the electric vehicle is optimized, so as to improve the service life of the electric vehicle.

Description

technical field [0001] The invention relates to a method for estimating the remaining cruising range of an electric vehicle in the field of automobiles, in particular to a vehicle-mounted big data acquisition and processing system and a method for estimating the cruising range of an electric vehicle based thereon. Background technique [0002] The cruising range of pure electric vehicles is only about 20% of the range of conventional internal combustion engine vehicles, which is a major factor preventing most consumers from purchasing electric vehicles. Therefore, providing a set of reasonable cruising range estimation methods can help drivers estimate the cruising range of vehicles in advance, reasonably adjust the use strategy of electric vehicles, and reduce the anxiety of electric vehicle users about cruising range. At present, major automobile manufacturers mainly conduct research on the cruising range estimation of electric vehicles from the perspective of calculating ...
