| Abstract: | It seems that the 8-bit microprocessor or 16-bit processor has not enough performance in more and more cases,especially for the real-time requirement of the ABS ECU.So more and more engineering design the ECU of the auto's using 32-bit microprocessor which can make the best of CPU's working time.Both hardware and software of wheel speed signal acquisition system are designed.A new method which is base on the frequency and period measurement methods is proposed to process wheel speed signal,and then real-time performance is analyzed.By means of on-line simulation,the test result shows that the design of hardware and software is correct.The system has steady and real-time character. |
