Differential lock control strategy of off-road vehicle based on fuzzy control
In order to solve the problems of poor robustness and heavy dependence on hardware accuracy of exiting differenti-al lock control algorithms,this paper proposes a differential lock control strategy for off-road vehicles based on fuzzy control.A fuzzy control strategy for the automatic differential lock control system is designed,and transplanted to a 1∶8 simulation model of an off-road vehicle for field testing.The robustness,response speed and vehicle passability of the control strategy under field slopes,potholes,grass,sand,gravel and other working conditions are tested.Experiments show that the differential lock fuzzy control strategy has good robustness and response speed under the above field conditions,and has significantly im-proved the slip rate of the vehicle,which greatly improves the passability of the vehicle.
