New energy trackless rubber-tyred vehicle long downhill sliding control algorithm

Abstract

The application provides a new energy trackless rubber-tyred vehicle long downhill sliding control algorithm and belongs to the vehicle control field; the problem of unstable speed of the vehicle during long downhill sliding is solved; the specific method is as follows: step S1: obtaining mechanical parameters; step S2: obtaining wheel radius and slope, and constructing a load-torque equation of the vehicle according to the mechanical parameters; obtaining power generation data of the vehicle and fitting a power generation-torque equation of the vehicle; step S3: obtaining working data and index data; adjusting the speed of the vehicle according to the slope, the working data and the load-torque equation and the power generation-torque equation; step S4: continuously obtaining the working data of the vehicle and adjusting the speed of the vehicle; the mechanical performance data and the working data of the vehicle are obtained, analyzed and processed, the speed of the vehicle during long downhill sliding is adjusted, and the stability of the vehicle is improved.
