The All-Wheel-Independent-Driving (AWID) electric vehicle has complex stress situation on off-road environment. To observe the load of each wheel, a dynamic model with 18 degrees of freedom (DOF) for 6WID electric vehicle is established in this thesis. The kinetic equation to solve wheel loads is created by Newton-Euler method. The load of each wheel is calculated according to their geometrical relationship with the whole vehicle. A wheel load observer is brought forward. The dynamic system model of the vehicle is co-simulated with Adams and Matlab/Simulink. The comparative results shows that this kind of observer can improve the wheel load observation accuracy effectively.
