Abstract :
The presented electric power steering system (EPS) based on embedded microprocessor DSP LF2407 applies to vehicle steering driving. The hardware of the system includes data acquisition module, data storage, calculating module and embedded microprocessor DSP LF2407. The data acquisition module is responsible for gathering, filtering and transformation for the torque, vehicle and motor speed signal; The data storage and the calculating module complete data memory and calculation; The output module fulfills the PWM signal transmission; DSP LF2407 controls the entire system and communication among various modules; The software of the system includes EPS controlled system software developed by the embedded microcomputer system. The system has realized the compound control joined the forward feed, enhanced the EPS control systems rapidity and the accuracy, obtained the better control effect
