The present invention provides an electric automobile low-temperature driving thermal management control method, a system, and an automobile. The method comprises: measuring an actual temperature of coolant on an air conditioner side; generating a corresponding passenger compartment heating priority signal according to the actual temperature and a target temperature of an air conditioner; determining an initial value according to the passenger compartment heating priority signal, a battery thermal management demand signal, and a current vehicle state; controlling heating of a passenger compartment and battery heating according to the determined initial value, to obtain a battery heating result; looking up a preset proportional valve adjustment table according to the battery heating result, to obtain an adjustment amount, and adding the adjustment amount and the initial value, to obtain a current adjustment value of an opening of a three-way proportional valve; acquiring the current adjustment value of the opening of the three-way proportional valve, and controlling the three-way proportional valve according to the current adjustment value. In the present invention, proper configuration of the overall thermal management of the vehicle is achieved by means of controlling the opening of the three-way proportional valve, so that a heating effect and discharge capacity of the battery are improved, while the heating of the passenger compartment is satisfied.
