Research on Economic Torque Distribution Control of Distributed Drive
Four-Axle Pure Electric Commercial Vehicles 2024-01-5040
Compared to passenger cars, commercial vehicles have relatively high fuel and
energy consumption, relatively high average annual driving mileage, and a wide
range of use. Therefore, energy-saving management of commercial vehicles is
crucial. For multi-axle distributed pure electric drive commercial vehicles, a
dynamic allocation control strategy for driving torque based on energy
consumption optimization is proposed. First, the basic idea of the driving
torque distribution control strategy was analyzed and a relevant mathematical
model was established. Then, the offline optimization of the distribution
coefficients of the driving torque for each axle was carried out through a
genetic algorithm, and the entire vehicle driving force distribution strategy
using the distribution coefficients as an online lookup table was determined.
Finally, through the joint simulation platform of TruckSim and MATLAB/Simulink,
simulation analysis was conducted for different driving conditions, and the
results showed that the designed driving torque distribution control strategy
can achieve the expected effect.
