Study on steering control strategy for high-speed tracked vehicle with hydrostatic drive

Steering control strategy for high-speed tracked vehicle with hydrostatic drive is designed based on analyzing the fundamental steering theories of the hydrostatic drive tracked vehicle. The strategy is completed by the cooperation between integrated steering control unit and pump & motor displacement controller. The steering simulation is conducted by using Simulink of Matlab. It is indicated that this steering control strategy can reduce the average vehicle speed automatically to achieve the driver's expected steering radius exactly in the case of ensuring not exceeding the system pressure threshold and no sideslip.
