The method for distributing loads between the cars of a family car comprises the following steps:

step S101, the control host 17 detects a car speed signal, and respectively senses load conditions on the driving car 1 and the auxiliary car 2 through the first pressure sensor 14 and the second pressure sensor 15;

step S103, when the speed of the car is greater than a preset limit value, the control host 17 controls the protection device 16 to respectively perform load distribution regulation on the first load regulator 12 and the second load regulator 13 through the load regulators;

wherein the load distribution adjustment specifically comprises: the first load regulator 12 reduces the load on the drive axle 1 to a preset value, and the second load regulator 13 increases the load on the auxiliary axle 2 to a corresponding preset value;
