Abstract
A payload estimation system and a method for estimating payload estimation using electric power steering (EPS) signals are provided. In certain embodiments, the aspects of the invention may include: receiving, by a payload detection module, multiple EPS signals to generate an additional axle load factor, determining, by a blend factor table, a load blend factor according to the additional axle load factor, generating, by a first multiplier, a blended nominal base assist signal by combining the load blend factor and a handwheel torque signal processed by a nominal base assist module, generating, by a second multiplier, a blended highload base assist signal by combining the load blend factor and the handwheel torque signal processed by a highload base assist module, and combining, by a merge module, the blended nominal base assist and the blended highload base assist to generate a motor torque command for the EPS system.
