The anti-lock braking system (ABS) is an important device to improve the vehicle's active safety. ABS can greatly improve the steering control capability during braking operation and shorten the braking distance. Today, with the increase in vehicle speed, ABS has been widely used. <br>     Taking the automobile as the research object, the ABS was studied. And completed a series of work: <br>     analyzed the dynamic situation of the wheel. Then, a hydraulic ABS model was established and ensured that major complications affected Wheeler's particle coefficient. <br>By comparing the performance of the electromagnetic speed sensor and the Hall speed sensor, we chose the latter and designed this sensor. <br>By analyzing the structure of the control system, we designed a real-time system, which uses a single-chip microcomputer 80c196kc produced by Intel Corporation, including signal input, single-chip system, output, drive circuit and other hardware parts. <br>After comparing the different schemes of the controller, the logic rate method is determined, and the combination of acceleration and slip rate is selected as the control parameter. Use the time gate method to calculate the wheel speed. <br>This article designs an ABS system based on the knowledge that I have mastered, and realizes the control function in theory, accomplishes my task. I have a deep understanding of car triggering theory and equipment. It expands my knowledge and improves my ability to solve problems.
