The invention discloses a control method and
system for a multi-configuration gearbox, and relates to the technical field of
intelligent control, and the method comprises the steps: calculating the total driving resistance of a vehicle, converting the total driving resistance into traction force, multiplying the traction force with the current vehicle speed, obtaining a power
estimation value, calculating the instantaneous change rate of an accelerator pedal opening
signal, and converting the instantaneous change rate into driver demand intensity. Constructing a macroscopic
feature vector; the required traction force is converted into the required torque of the gearbox input shaft, the thermodynamic entropy yield is obtained, the comprehensive cost is calculated, and a target configuration is screened; and the current gearbox configuration is judged based on the target configuration, and gearbox configuration switching is intelligently controlled. According to the method, the comprehensive performance of the gearbox is improved by utilizing the dynamic calculation of the total driving resistance of the vehicle and the intensity required by a driver, combining the real-time
road condition and the driving behavior, optimizing the
configuration selection of the gearbox, matching different driving scenes and utilizing the calculation of the thermodynamic entropy yield and the switching transient excitation potential.
