Abstract

The invention relates to the technical field of vehicles, and specifically discloses a method for switching working modes of a hybrid vehicle. The method for switching working modes of a hybrid vehicle measures the power of the engine in the series working mode and the parallel working mode based on the vehicle power, and then measures the power of the engine in the The power test series minimum specific fuel consumption and parallel specific fuel consumption, and then according to the test results of different vehicle power draw series vehicle fuel consumption characteristic map and parallel vehicle fuel consumption characteristic map, when the vehicle is actually running, according to the series vehicle fuel consumption characteristic map From the perspective of specific fuel consumption of the engine, this method can maximize the efficiency by selecting the working mode with lower fuel consumption in the parallel working mode and the series working mode. Use the high-efficiency zone of the engine to reduce the fuel consumption of the vehicle and improve the economic level of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a hybrid vehicle working mode switching method and the hybrid vehicle. Background technique [0002] Energy and environmental issues are becoming more and more prominent, and the lack of storage battery technology and charging technology facilities makes the research and application of hybrid electric vehicles more and more extensive. Hybrid vehicles have multiple working modes, and the energy transmission chains and torque transmission paths of different working modes are different, and their power performance, economic performance, and driving performance are all different. Give full play to the advantages of each working mode, and carry out at the right time. Hybrid working mode switching can give full play to the biggest advantages of hybrid vehicles, therefore, the control of hybrid working mode switching conditions is particularly important. [0003] In the prior art, the...
