The invention relates to the field of force sensors, in particular to a multi-dimensional force sensor for trailer traction control. A square column of the shear beam structure serves as an elastic sensitive element in the Y-axis direction and the Z-axis direction, and sensitive deformation of vertical force and lateral force is achieved. The cross beam structure serves as an elastic sensitive element in the X-axis direction, and sensitive deformation to axial tension and axial pressure is achieved; the X-axis sensing assembly collects the axial force in the X-axis direction. The Y-axis sensing assembly collects vertical force in the Y-axis direction; the Z-axis sensing assembly collects lateral force in the Z-axis direction; the circuit board is used for carrying out coupling calculation on component forces in the X-axis direction, the Y-axis direction and the Z-axis direction, and CAN digital signal output is achieved through a signal line. The problems that an existing trailer control system cannot accurately sense multi-dimensional stress information between a main vehicle and a trailer in real time, cooperative control lags behind, and precision is insufficient are solved.
