Embodiment Construction

[0035] In order to enable those skilled in the art to further understand the features and technical content of the present invention, the following describes the embodiments of the present invention in detail with reference to the accompanying drawings and embodiments.

[0036] Aiming at the current manual transmission hybrid electric vehicle model, the vehicle does not have a gear shift prompt function, and the vehicle cannot work in the optimal fuel consumption range, an embodiment of the present invention provides a hybrid electric vehicle gear shift prompt method to recommend the best economical gear position , So as to help the driver achieve the goal of improving fuel economy.

[0037] figure 1 It is a flow chart of the shift prompt method of a hybrid electric vehicle according to an embodiment of the present invention. When all shift activation conditions are met, the following steps are included:

[0038] Step 101: Obtain operating parameters of the hybrid electric vehicle, w...

Abstract

The invention relates to the technical field of hybrid electric vehicles, in particular to a gear shifting reminding method of a hybrid electric vehicle. The method comprises the steps that under the condition of meeting a gear shifting activation condition, the running parameters of the hybrid electric vehicle are obtained, and comprise the current vehicle speed, the current engine rotating speed, the current engine output torque and the current motor output torque; the current gear value is calculated according to the proportional relation between the current vehicle speed and the current engine rotating speed; upshift target vehicle speed and down-shift target vehicle speed corresponding to the current gear value are determined through the sum of the current engine output torque and the current motor output torque; if the current vehicle speed is larger than the upshift target vehicle speed, a user is reminded of upshift information; and if the current vehicle speed is smaller than the down-shift target vehicle speed, the user is reminded of down-shift information. By means of the method, optimal fuel economy gear recommendation is carried out, and a driver is helped to achieve the aim of improving the fuel economy of the hybrid electric vehicle.

Description

Technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a shift prompt method for hybrid electric vehicles. Background technique [0002] In today's society, 25% of carbon dioxide emissions come from automobile emissions. Therefore, with the increasing popularity of automobiles, automobile energy saving and emission reduction are of great significance to the energy conservation and emission reduction of the entire society. [0003] As the environmental protection measures of countries around the world become more and more stringent, and more and more hybrid vehicles are used, how to better reduce the fuel consumption of hybrid vehicles will be a major problem. When driving a manual transmission hybrid vehicle, because the driver has less energy-saving technology, and beginners cannot grasp the appropriate shift timing, this will cause the vehicle to fail to work in the optimal fuel consumption range, which means more Fuel c...
