1. A thermal management system for a vehicle, the system comprising:
a controller;
a first coolant circuit with a first coolant pump;
a second coolant circuit with a second coolant pump; and
a multiway valve that completes both the first and the second coolant circuits,
wherein the first coolant pump, the second coolant pump, and the multiway valve are adapted to be automatically actuated via the controller,
wherein the first coolant circuit and the second coolant circuit are adapted to be fluidically connected to one another via the multiway valve as a function of the actuation of the multiway valve,
wherein the first coolant pump, the second coolant pump, and the multiway valve are matched to one another and adapted to be operated such that a coolant circulates essentially in the first coolant circuit when the first coolant pump is switched on and when the second coolant pump is switched off,
wherein, when the first coolant pump is switched on and when the second coolant pump is switched on, the coolant circulates in the first coolant circuit and in the second coolant circuit that is fluidically connected to the first coolant circuit via the multiway valve, and
wherein the first coolant circuit has a first flow section and a second flow section arranged parallel to the first flow section in fluid dynamic terms, wherein the first flow section and the second flow section are fluidically connected to one another in every operating state of the thermal management system, and wherein the first flow section is adapted to be fluidically connected directly to the second coolant circuit via the multiway valve, and wherein the second flow section is adapted to be fluidically connected directly to the first coolant pump via the multiway valve.
