Abstract: Disclosed are a follow-up steering control system for a multi-axle automobile crane and the multi-axle automobile crane, wherein in a steering state of the multi-axle automobile crane, an output oil pressure of a first oil pressure output port is greater or less than that of a second oil pressure output port; a piston rod of a left-turning hydraulic cylinder (8) is lengthened and a piston rod of a right-turning hydraulic cylinder (13) is shortened, or the piston rod of the left-turning hydraulic cylinder (8) is shortened and the piston rod of the right-turning hydraulic cylinder (13) is lengthened; and a first knuckle arm (17) and a second knuckle arm (18) are driven to make a rear left steering wheel (11) and a rear right steering wheel (15) turn left or right. The follow-up steering control system of the multi-axle automobile crane provides a hydraulic control follow-up steering control method for a vehicle with an active steering rear axle, so that the low-speed steering maneuverability and cornering behaviour of the multi-axle automobile crane are improved, and the drifting which may occur during high-speed driving is avoided.
