Problems solved by technology

In addition, the vehicle is inevitably affected by environmental information such as road conditions and weather during driving, which makes the mileage of the vehicle change greatly.
However, the existing technology only estimates the cruising range at the current moment based on the remaining hydrogen in the hydrogen bottle and the hydrogen consumption rate at the current moment, without considering the impact of the driving environment of the vehicle or the driving mileage of the power battery, so it is impossible to accurately predict the fuel consumption. battery driving range

Abstract

The invention discloses a driving range prediction method, device and equipment and a storage medium. The method comprises the following steps: obtaining the available hydrogen amount, the residual electric quantity of a power battery and environment information of a vehicle; determining the average energy consumption of the vehicle according to the environment information; determining the total energy of the vehicle according to the available hydrogen quantity and the residual electric quantity of the power battery; and predicting the driving range of the vehicle according to the total energyand the average energy consumption. By means of the technical scheme, the endurance capacity of the fuel cell and the endurance capacity of the power cell can be integrated, influences of environmental factors such as weather conditions and road traffic conditions are considered, the driving range of the vehicle is accurately predicted, and the problem of range anxiety of a driver is relieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicles, and in particular to a method, device, device and storage medium for predicting driving range. Background technique [0002] With the increasingly prominent environmental and energy issues, new energy vehicles have become a research hotspot for major automobile manufacturers and R&D institutions in the world. Among them, fuel cell vehicles are generally considered to have broad development prospects due to their high efficiency and near-zero emissions. prospect. However, due to the influence of driving conditions, weather conditions, geographical location and other factors, the driving range of fuel cells varies greatly. Accurately predicting and informing the driver of the driving range will greatly alleviate the range anxiety problem. [0003] At present, most fuel cell vehicles use hybrid drive. On the basis of fuel cells, power batteries are added as another power ...
