AVERAGE FRICTION LEARNING AND AVERAGE FRICTION CHANGE ESTIMATION |
摘要 |
A learning function is configured to determine a plurality of piecewise linear function coefficients based on measured data for an electric power-assisted steering (EPS) system. The measured data include a vehicle speed. The learning function is further configured to model a hysteresis loop of the EPS system using a piecewise linear function based on the plurality of piecewise linear function coefficients to determine an average friction. An average friction change compensator is configured to adjust friction-based EPS system compensation based on the average friction for a plurality of vehicle speed intervals of the vehicle speed. |
