In order to lighten abrasion of braking system of hybrid electric tracked vehicle, electric-mechanical composite braking method was proposed according to characteristic of hybrid electric transmission. By means of analyzing performance of electric braking and mechanical braking and three-segment composite braking strategy, this paper put forward two-segment electrical-mechanical composite braking strategy. Simulation results of MATLAB/Simulink indicated that the two-segment electric-mechanical composite braking strategy might reduce the demand of mechanical braking force and be well applied.
