Abstract

The embodiment of the present invention discloses a new energy vehicle navigation fuel-saving method, system and vehicle. The method includes: acquiring the current driving route of the vehicle and the road condition information ahead corresponding to the driving route; acquiring the current battery power of the vehicle; judging Whether the road condition information ahead and the current battery level meet a preset condition; when the road condition information ahead and the current battery level meet a preset condition, obtain a fuel-saving strategy corresponding to the preset condition and acquire the preset condition A corresponding fuel-saving strategy; controlling the engine operation of the vehicle according to the fuel-saving strategy. The vehicle using the present invention can store power in advance in the high-speed area where the vehicle is running smoothly according to the road condition information ahead of the navigation and the current battery power situation, so as to avoid the reduction of the engine operating frequency and the increase of fuel consumption in the congested road section with low speed. The vehicle NVH will be greatly improved.

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...
