Embodiment Construction
[0040] The scheme will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments,
[0041] This embodiment provides a method for estimating the cruising range of a fuel cell electric vehicle, which first uses a probabilistic neural network to identify the current operating condition type, and then calculates the average hydrogen consumption per 100 kilometers of the driving conditions and the hydrogen consumption per 100 kilometers of the current operating conditions. On this basis, the hydrogen consumption per 100 kilometers of the current operating conditions corrected by the proportion of the current operating conditions in the driving conditions is calculated, and the remaining available hydrogen mass is calculated. Finally, the available hydrogen mass is divided by the hydrogen consumption per 100 kilometers to calculate the cruising range. , and use the historical working condition data to correct the cruising range t...

The invention provides a method, device and storage medium for estimating the cruising range of a fuel cell electric vehicle. First, the probabilistic neural network is used to identify the type of the current working condition, and then the average hydrogen consumption per 100 kilometers of the driving condition and the current working condition are calculated. Hydrogen consumption per 100 kilometers. On this basis, the hydrogen consumption per 100 kilometers of the current working condition is corrected based on the ratio of the current working condition to the driving condition, and then the remaining available hydrogen quality is calculated. Finally, the available hydrogen quality is divided by the hydrogen consumption per 100 kilometers. The cruising range can be corrected by borrowing historical working condition data to improve the accuracy of calculation and provide reference for users.
Description
technical field [0001] The invention belongs to the technical field of hydrogen fuel cell vehicles, and relates to a technology for estimating the cruising range of a fuel cell electric vehicle. Background technique [0002] Fuel cell electric vehicles convert chemical energy into electrical energy through a chemical reaction between hydrogen and oxygen, thereby driving the motor to achieve the purpose of outputting power for the vehicle. Compared with traditional fuel vehicles, that is, hybrid vehicles, the reaction product of fuel cell electric vehicles is water, which can achieve zero emissions, and hydrogen is a renewable energy source that fully meets the development requirements of energy conservation and emission reduction. At present, there are already fuel cell vehicles on sale, but due to the special hydrogen energy used and the high cost of fuel cell engines, there are not many fuel cell electric vehicles at present. [0003] It is precisely because the current d...
