Embodiment Construction
[0094] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0095] Such as figure 1 As shown, an intelligent prediction method for power supply of unmanned vehicles in an extreme rainstorm environment includes the following steps:
[0096] Step 1: Obtain the historical driving data of unmanned vehicles in the rainstorm environment;
[0097] The historical driving data includes rainfall resistance at each moment, road water resistance, slope power loss, vehicle battery temperature, power consumption rate, and remaining power;
[0098] Step 2: Construct a battery power consumption rate fitting model for unmanned vehicles based on wavelet neural network;
[0099] Taking the rainfall resistance, road water resistance, slope power loss, and vehicle battery temperature in each specified time interval T in the historical driving data as input data, the specified time interval T is 30s in this example, and the rainfal...
