Investigation of Control Strategy for Hydraulic Auxiliary Braking of Tracked Vehicle Based on Pump Efficiency Analysis

Abstract:

On the basis of hydrostatic and hydraulic auxiliary braking system for tracked vehicle, the hydraulic pump efficiency was analyzed and discussed. And the model according to the performance analysis was set up, and the optimal working line in which the hydraulic pump working at the highest efficiency level was obtained. And an energy regenerative braking control strategy was proposed which can lead to the optimal matching of hydraulic coupler, hydraulic pump/motor. The computing results show that the hydraulic pump/motor can achieve efficient operation, and the energy regeneration efficiency of braking was improved obviously with the regenerative braking control strategy under the safe braking condition.
