Description

technical field [0001] The invention relates to a distributed four-wheel electric drive new energy vehicle experimental system based on hardware in the loop. Background technique [0002] Distributed electric drive new energy vehicles distribute the power sources near or within the driving wheels to minimize losses during power transmission and improve transmission efficiency. At the same time, the dispersion of the driving force makes it easier for the car to independently control each driving wheel according to the road surface conditions, which maximizes the controllability of the car's drive, improves the adhesion rate between the wheels and the road, and improves the handling stability. In addition, due to the decentralized arrangement of the drive system, it is beneficial to improve the seating space in the car and improve the ride comfort. Based on the above advantages, domestic and foreign experts, scholars and automobile manufacturers have actively carried out rese...
