Technical solutions are described for a payload detection module that detects payload using one or more steering system control signals and generates an axle load factor. An example payload detection module includes a rack torque module to determine a rack torque, a reference model module to determine a reference rack torque for the steering system based on a load scale factor, and a load factor calculation module to compute the axle load factor based on a difference between the rack torque and the reference rack torque. Further, a blend factor module determines a load blend factor according to the axle load factor. Further yet, a signal combiner combines a blended nominal base assist and a blended highload base assist according to the load blend factor, the combination modifying a motor torque command, the motor torque command being sent to a motor to generate assist torque.
