Oil-saving system based on road scene and driving intention and control method

Abstract

The invention relates to the technical field of automobile control methods, in particular to an oil -saving system based on a road scene and a driving intention and a control method. The system comprises a road scene recognition module, a fuel saving condition judgment module, a speed control method acquisition module, a driving intention recognition module, a power demand recognition module and a control module. The speed control method of the vehicle is obtained according to the road condition and the front vehicle condition, the driving intention of a vehicle driver is recognized, if the driving intention belongs to the set intention, the power demand of the vehicle is obtained in combination with the speed control method and the driving intention, and the power assembly is controlled according to the power demand to enable the engine to operate in the economic area. The control method is extremely simple, the power assembly of the vehicle is controlled in combination with the road scene and the driving intention, and the oil saving effect of the power assembly of the vehicle is improved.

Description

technical field [0001] The present invention relates to the technical field of automobile control methods, in particular to a fuel-saving method and system based on road scenes and driving intentions. Background technique [0002] With the popularization of automobiles, the impact of vehicles on the environment is becoming more and more obvious, and the consumption of energy is also increasing. Therefore, reducing vehicle fuel consumption has always been an important goal of major automobile companies. In the current industry, a lot of work has been done on automobile fuel consumption, but most of them are on the optimization of vehicle structure (wind resistance, rolling resistance, etc.), engine technology and other aspects. The consideration of the vehicle driving scene and the needs of the driver is relatively weak. [0003] A common technical solution in the current industry is to adjust the engine operating parameters through the driver's active selection of the vehi...

Problems solved by technology

[0005] However, the problem considered by this scheme is relatively simple. It only considers that the accelerator opening is kept at the minimum value without violating the driving intention. In fact, the fuel economy is controlled by controlling the opening of the accelerator pedal, which affects the fuel economy. There are many factors, not only at the level of the driver, but also factors such as road scenes. Although the impact of these factors can be fed back to the level of driving intention in the end, if the control is only based on driving intention, different driving members can make a big difference

Therefore, the level considered in this plan is relatively one-sided, and it can only improve fuel economy to a certain extent, and cannot really improve the fuel-saving function of the engine.
