The invention discloses an automotive heat pump air-conditioning system and a control method thereof. The automotive heat pump air-conditioning system comprises a compressor, a four-way reversing valve, an in-vehicle fan, an in-vehicle heat exchanger, an out-vehicle fan and an out-vehicle heat exchanger, and further comprises an economizer assembly, a main expansion valve assembly and a compressor with an auxiliary air inlet. The economizer assembly is connected with the main expansion valve assembly, the cut-off electromagnetic valve and the in-vehicle heat exchanger. The cut-off electromagnetic valve is connected with an auxiliary air inlet of the compressor. The economizer assembly comprises a subcooler and a middle injection expansion valve, the subcooler and the middle injection expansion valve have a common end, and the tail end of the middle injection expansion valve is connected with the subcooler; a main expansion valve of the main expansion valve assembly is connected with two one-way valve branches in parallel, and each one-way valve branch is provided with two one-way valves which are arranged in series in the same flow direction. The air conditioning system not only meets the requirements of drivers and passengers in different areas for cooling and heating, but also can ensure that the system can operate efficiently and reliably in an energy-saving manner under any working condition.
