To advance active safety of distributed drive electric vehicles (DDEVs), an active forward steering (AFS) controller is constructed, which adopts sliding mode control algorithm (SMC). The errors that the real value minus the value of expectation of yaw velocity and sideslip angle were designed as the controller's sliding mode surface, which contributes to strengthening the lateral stability and yaw stability. The chattering of the system was reduced by using the saturation function, where the constant speed approach law with small computation and good robustness is selected to reduce chattering generated in the control process. The wheel drive/braking toque was distributed in equal proportions according to the axle load ratio through the set distribution rules. Carsim and Matlab/Simulink co-simulation were used to investigate the effectiveness of the controller. The results indicate that the AFS controller can improve the driving stability and steering ability of the vehicle well.
