Embodiment 1

[0054] see figure 1 , which shows the hybrid drive mode adjustment method in the first embodiment of the present invention, including steps S11-S15.

[0055] S11. Acquire the current operating conditions of the vehicle, and calculate thermal efficiency values ​​in different driving modes based on the vehicle hybrid architecture and the current operating conditions.

[0056] The current working condition of the vehicle is obtained. The current working condition includes the vehicle speed demand and the torque demand. The vehicle speed and torque correspond to the generated wheel end demand power, that is, the wheel end demand power = torque * vehicle speed.

[0057] Calculate the thermal efficiency value in parallel direct drive mode, EV pure electric mode, series mode, charge load point transfer power generation mode, and boost load point transfer mode according to the required power at the wheel end. The higher the thermal efficiency value, the lower the vehicle power consum...

Abstract

The invention provides a hybrid driving mode adjusting method, system and equipment, and the method comprises the steps: obtaining the current working condition of a vehicle, and calculating thermal efficiency values in different driving modes based on a vehicle hybrid architecture and the current working condition; comparing the thermal efficiency values under different driving modes, and determining an optimal driving mode under the current working condition; judging whether the setting time of the optimal driving mode reaches preset time or not; if yes, the vehicle driving mode is adjusted to the optimal driving mode; and if not, maintaining the current driving mode. According to the hybrid driving mode adjusting method, system and equipment, the current working condition of the vehicle is obtained, the heat efficiency values of the vehicle in different driving modes are correspondingly calculated, then the optimal driving mode is determined through comparison, the vehicle is adjusted to the optimal driving mode, the vehicle can work in a driving mode in the optimal driving mode, and the driving efficiency of the vehicle is improved. And the vehicle efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, and in particular, to a method, system and device for adjusting a hybrid drive mode. Background technique [0002] With the implementation of the policy of average fuel consumption points and new energy points, the fuel consumption status of traditional vehicles produced by OEMs can no longer meet the requirements of national standards, and hybrid vehicles with low power consumption have become the mainstream trend. [0003] A hybrid vehicle, also known as a hybrid vehicle (Hybrid Power Automobile in English), refers to a vehicle equipped with more than two power sources: a battery, a fuel cell, a solar cell, and a generator set of a diesel locomotive. Currently, a hybrid vehicle generally refers to a diesel locomotive. A car with an alternator plus a battery. [0004] In the prior art, most of them reduce the fuel consumption by modifying the shift line, improving the thermal efficiency of ...
