The invention provides an electric bus collision safety control system and a control method of the system. The electric bus collision safety control system comprises a contact type collision sensor, an acceleration sensor, a power battery system breaking controller, contactors, an alarm unit, a display unit, single-pole double-throw switches, a power battery system and a driving motor; and the power battery system is composed of a plurality of power battery sets. When a certain power battery set judges that collision happens through a breaking control algorithm, the power battery system breaking controller controls the contactor in the certain power battery set to be broken, and the voltage reduction breaking of the certain power battery set is achieved; meanwhile, the external contactor of the certain battery power set is controlled to be closed, and accordingly, reconnection of the other power battery sets can be achieved, and box division breaking is completed; and dangers of high voltage, combustion, explosion and the like of an electric bus under the collision condition are avoided, and meanwhile, brake, turning and the like of the electric bus under the collision condition can be effectively ensured.
