Abstract:
1. A vehicle comprising an electric power assisted steering (EPAS) system wherein the EPAS system is configured to use at least an approximation of a torque contribution (Tweight) to a steering wheel torque caused by the presence of one or more weights disposed in a steering wheel of the vehicle in an off-center position to compensate for that torque contribution (Tweight) by computing at least one of a corrected value of steering wheel torque from a detected value of steering wheel torque that is then used to determine an amount of assistive motor torque to be applied by the EPAS system, or a corrected value of assistive motor torque to be applied by the EPAS system, thereby accounting for the presence of the one or more weights in the steering wheel in the determination of an assistive motor torque to be applied by the EPAS system.
