Abstract

Based on the hydrostatic and hydraulic auxiliary braking system of tracked vehicle, the hydraulic pump/motor efficiency model according to the performance analysis was set up, and the optimal working line in which the hydraulic pump/motor 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.
