description	The invention provides a fault-tolerant control method of a high-voltage power distribution system for a distributed driving vehicle. The method comprises the steps of collecting magnitudes of currents of all branches in the high-voltage power distribution system in real time; separately judging whether the currents of all the branches are larger than a preset safety current threshold value or not, and if yes, switching off contactors; if the currents of all the branches at the current moment are all within the safety current threshold value, utilizing a third-order exponential smoothing algorithm in combination with current and historical current values of all the branches at the current moment, calculating current values after a certain period of time in the future, judging whether the current values after a certain period of time in the future are larger than the safety current threshold value or not, and if yes, switching off contactors of the corresponding branches, and conductinglimp processing on the v
