Abstract
A vehicle having a driving assist system and an electric power assist steering system coupled to the driving assist system. The driving assist system transmits an assist torque request for reception by the electric power assist steering system for enabling the electric power assist steering system to adjust its outputted assist torque to accommodate requirements of the driving assist system. The assist torque request specifies a requested additional assist torque required by the driving assist system from the electric power assist steering system. In response to receiving the assist torque request, the electric power assist steering system performs an operation for determining a column torque offset as a function of both a force being applied by a driver of the vehicle on a steering column of the vehicle and the requested additional assist torque required by the driving assist system.
