An electronic control hydraulic active limited slip differential（ELSD） and its control system were designed.Dynamics model of the driving process was conducted based on the drive system characteristics of ZL50 loader.A control algorithm of increment-PID was adopted to build imitating system that used in front and rear differential independently.Application for μ-slipt road shows that ELSD will confine tire slipping and improve whole loader driving performance.
