The invention discloses an automotive heat pump system. The automotive heat pump system comprises a dehumidification route which is used for supplying part of refrigerating fluid to an evaporator after the refrigerating fluid in a refrigerating fluid circulating route flows through a first expansion device and before the refrigerating fluid is led into an external heat exchanger so as to dehumidify the interior of a vehicle in a heat pump mode; accordingly, when the interior of the vehicle is dehumidified and before the refrigerating fluid is led into the external heat exchanger with higher pressure than the evaporator, the refrigerating fluid is allowed to smoothly flow to the low-pressure evaporator through the dehumidification route and dehumidifies the interior of the vehicle stably.
