Abstract

The invention discloses a hybrid electric vehicle driving range calculation method and a hybrid electric vehicle, and belongs to the technical field of automobiles, the hybrid electric vehicle driving range calculation method comprises the steps that within a first preset driving distance S, the calculation formula of the residual total driving range RTEal is described in the description; after the nth preset driving distance S, the calculation formula of the residual total driving range RTEal-n is described in the description.The average oil consumption, the average power consumption, the minimum value of available energy of a power battery pack, a battery life attenuation coefficient and a change coefficient of gradual consumption of the oil quantity of an oil tank are considered, and compared with the prior art, the method has the advantages that the driving range under the remaining oil quantity and the electric quantity can be truly and reliably calculated, and a user can visually know the driving mileage state of the hybrid electric vehicle.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for calculating the mileage of a hybrid electric vehicle and the hybrid electric vehicle. Background technique [0002] Hybrid electric vehicles have both good power and economy, and have been promoted and developed by more and more automobile manufacturers. Hybrid vehicles are mainly powered by motors and engines. In order to calculate the mileage of the whole vehicle more effectively, it is necessary to consider the two power sources of the motor and the engine comprehensively, because the calculation of the driving mileage is related to the amount of fuel and The use of power and the operating range of the engine and motor are related. If the engine and motor operation judgment and energy accumulation calculation cannot be effectively carried out, it will inevitably affect the calculation of the vehicle mileage, and then affect the user's perception of the driving...
