You can help people complete the task in the case of some tests can not survive. This thesis is to study the SOPC (system-on-chip programmable), based on the proposed FPGA-based smart car can automatically collect information running track program. Using FPGA to achieve the desired signal for each module. Dissertation consists of three parts: in which signals the need for the smart car based on the analysis, design the corresponding software program. By QuartersⅡ preparation of the corresponding software program, the first part is to generate a signal required for driving the CCD, this part has a plurality of PWM (pulse width modulation) wave control signal, A0 (analog voltage output) signal, SI (serial input) of the input signal, CLK (clock signal); the core of the CCD（Charge-coupled device） signal processing poem, if this part of the total solved basically solved the problem of the second part is the signal required for driving the motor, this part requires a set PWM wave control signal; part III servo signal is the desired signal, this part requires a set PWM wave control signal.
