The invention relates to a passenger car hand brake emergency releasing system and a releasing method for the same. The system comprise a hand brake air storage cylinder, a spare air storage cylinder, an emergency switch, an air pump, a hand brake, a quick releasing valve and a hand brake air chamber, wherein an air outlet of the air pumping is connected with a first air inlet of the hand brake air storage cylinder via a first single-way valve; a first air outlet of the hand brake air storage cylinder is respectively connected with an air inlet of the hand brake and an air inlet of the quick releasing valve; an air outlet of the hand brake is connected with a control port of the quick releasing valve; an air outlet of the quick releasing valve is connected with the air inlet of the hand brake air chamber; a second outlet of the hand brake air storage cylinder is connected with an air inlet of the spare air storage cylinder via a second single-way valve; and an air outlet of the spare air storage cylinder is connected with a second air inlet of the hand brake air storage cylinder. When brake air pressure cannot be provided to the hand brake air chamber due to faults of the passenger car, compression air can be temporarily provided to the hand brake system, so hand brake can normally work; and inconvenience due to incapability of the hand brake to operation and maintenance of the passenger car can be avoided.
