Navigation oil-saving method and system of new energy vehicle and vehicle

Abstract

The embodiments of the invention disclose a navigation oil-saving method and system of a new energy vehicle and the vehicle. The navigation oil-saving method comprises the steps that a driving route of the current vehicle and front road condition information corresponding to the driving route are acquired; the current battery power of the vehicle is acquired; whether the front road condition information and the current battery power meet preset conditions or not is judged; an oil-saving strategy corresponding to the preset conditions is acquired when the front road condition information and the current battery power meet the preset conditions; and an engine of the vehicle is controlled to work according to the oil-saving strategy. By adopting the navigation oil-saving method and system ofthe new energy vehicle and the vehicle, electric quantity is stored in advance in a high-speed area with smooth vehicle driving road conditions according to the navigated front road condition information and the current battery power condition, so that the situations that the engine operation frequency is reduced and the oil consumption is increased in a congested road section with low speeds areavoided, and meanwhile, the NVH of the whole vehicle can be greatly improved in a low-speed working condition.

Description

technical field [0001] The invention relates to the technical structure field of new energy vehicles, in particular to a new energy vehicle navigation fuel-saving method, system and vehicle. Background technique [0002] Today, as the world's petroleum fuels are decreasing, the efficiency of energy use is particularly important. For new energy hybrid vehicles, the improvement of fuel consumption rate can greatly save energy and reduce the pollution of the atmospheric environment caused by vehicle emissions. At present, affected by the rapid growth of global car ownership and the explosion of information, as well as the changes in traffic facilities and road environment, the global road network is becoming more and more complex. Under this background, the fuel-saving measures of new energy vehicles in congested roads appears to be particularly important. [0003] When a hybrid vehicle operates in low-speed, low-battery traffic jam conditions, the engine works in the low-eff...
