When making a model, a car manufacturer often mention a word——“Driving mode. The main handling must be moved in motion, promoting the provincial oil, the ECO mode, the four-wheel drive mode of SUV, the mode of mixing models, the pure electric mode, the hypothesis, the pure oil mode also has a side oil Mode, etc. About traditional power cars, these modes are very good.
If you want to drive, you will naturally move mode, pursuing economic non-ECO or even Eco +, outdoor cross-country, four-wheel drive custom; then, so much about mixing cars, how to choose how to choose? How can I maximize oil and use electrical energy? You will definitely dismissive, this is also a problem, Xiaobai understands well. Running high speed, use the engine, affirm that pure electric cost on the Second Ring Road of the Emperor, as for what is still power generation while working, isn't it the system software preset to a certain extent? But you have to understand that there is always three madmen in the engineer's team, they always hope that the numbers can be more beautiful, even if they only increase 1%. In the Charms University of Technology in Gothenburg, Gothenburg, there is an electrical engineering professional freshly released Ph.
D. Viktorlarsson, in his own doctoral thesis, I talked about this topic. Of course, as a research topic of doctoral thesis, it is not possible“High-speed road engine, peak period is the rhythm of the battery, but it is more high.
Larsson uses a series of mathematical algorithms such as hierarchical algorithms, convex planning, and Hamilton functions. Mathematical modeling for mixing vehicles, to draw low power distribution. Then, Dr.
Larsson compiled these algorithms into a program. We all understand that the fuel consumption of plug-in hybrid is much lower than traditional power vehicles, and Toyota Puri is only 2.6L, while Larsson said that after using this procedure, the mixing vehicle can be on this basis.
Reduce 10%. The program starts to count daily driving data, and calculate the daily travel route of the vehicle. When the vehicle is driving on the established route, it is possible to determine that the vehicle is in a detailed location of the route, and then balance the battery and the power output of the battery according to statistics.
Larsson wants the software to determine which driving mode is lower and automatically switched to the corresponding mode, so software not only knows how long this distance is, and it is necessary to understand the corresponding road, such as that is always uphill, then clear The use of the engine can obtain greater traction, also more economical, and use the battery, it will cost too fast. It can be inferred that the software extraction is not only the driving data of the vehicle, and the navigation data is also included. The software will upload driving data and route data on the vehicle to the service and preset power allocation for the route.
This way, the work to be done is quite simple, as long as reading time data is good. On Monday morning, you can call up the bus. LARSSON established an algorithm model to detect in Volvo's V60.
The V60 is inserted. The motor drives the rear wheel, the engine drives the front wheel, when necessary, the engine can also drive the generator to charge the battery, the battery can be added, and thus, in this model, there are two degrees of freedom. .
