Disclosed are a vehicle heat pump system that optimizes the configuration of the coolant line to secure an additional heat source for electronic component waste heat in heat pump mode, and a control method thereof. The vehicle heat pump system, in a refrigerant line, is provided with: a compressor which compresses and discharges a refrigerant; at least one heat exchanger provided inside an air conditioning case to exchange heat between the refrigerant and air within the air conditioning case; an outdoor heat exchanger provided outside the air conditioning case to heat exchange the refrigerant with the outdoor air; and an expansion means to expand the refrigerant. In the vehicle heat pump system, a chiller is provided upstream of the compressor in the direction of refrigerant flow, and the chiller is configured to simultaneously secure a heat source for electronic component and a heat source for air.
