A front and rear wheel load distribution control unit which provides excellent driving operability of a coupled vehicle and improves durability of a driving unit. To this end, the control unit is a front and rear wheel load distribution control unit for a coupled vehicle with a front vehicle (1) and a rear vehicle (3) being coupled, including an inter-axle differential lock (71) between a front axle (91) and a rear axle (92) for eliminating a rotational differential between the front axle (91) and the rear axle (92), and includes a crossing angle detecting sensor (33) for detecting a crossing angle of the front vehicle (1) and the rear vehicle (3), a front axle rotation sensor (31) for detecting rotation of the front axle (91), a rear axle rotation sensor (32) for detecting rotation of the rear axle (92), and control means (20, 20a, 20b, 36) for operating the inter-axle differential lock (71) in response to a crossing angle signal from the crossing angle detecting sensor (33), a rotation signal from the front axle rotation sensor (31), and a rotation signal from the rear axle rotation sensor (32).
