The invention relates to a vehicle thermal management system, a control method and device thereof, a storage medium and a vehicle, and aims to solve the problems that cooling liquid cannot be reasonably distributed when a main driving bridge and an auxiliary driving bridge are cooled in the prior art; the technical problems of energy waste of cooling liquid and insufficient cooling of a main driving bridge and an auxiliary driving bridge are solved. The method comprises the following steps: obtaining a main driving branch cooling demand and an auxiliary driving branch cooling demand; the opening degree of a port A and a port B of the first three-way proportional valve (5) is adjusted according to the cooling requirement of the main drive branch so as to adjust the flow of cooling liquid flowing through the main drive cooling branch, and the opening degree of the port A and the opening degree of the port B are in direct proportion to the cooling requirement of the main drive branch; the opening degrees of a port A and a port C of the first three-way proportional valve (5) are adjusted according to the cooling requirement of the auxiliary driving branch so as to adjust the flow of cooling liquid flowing through the auxiliary driving cooling branch, and the opening degrees of the port A and the port C are in direct proportion to the cooling requirement of the auxiliary driving branch.
