| Abstract: | The structure and mechanism of an electric power steering system(EPS) were introduced.A whole design project of MC9S12P64-based electronic control unit(ECU) was presented.And particularly the hardware on controller,current sampling and driving circuit were designed.The control strategies and system programs were proposed.Test-bed experiment and full-car experiment were completed.Based on experimental results,the ECU has been proven effective and can achieve the best power steering function in a variety of driving. |
