The invention discloses a vehicle-mounted natural gas system without pressure relief emission and a control method thereof.The vehicle-mounted natural gas system comprises an LNG energy storage tank and a corrugated energy storage device communicating with the LNG energy storage tank, and the LNG energy storage tank comprises a plurality of pressure relief openings communicating with the corrugated energy storage device; the corrugated energy storage device comprises a corrugated pipe energy storage chamber communicating with the pressure relief opening and an energy storage vaporizing chamber communicating with the corrugated pipe energy storage chamber, and gas in the corrugated pipe energy storage chamber can flow to the energy storage vaporizing chamber so that the pressure of the corrugated pipe energy storage chamber and the pressure of the energy storage vaporizing chamber can be kept balanced. The corrugated energy storage device comprises a corrugated pipe energy storage chamber communicated with the
