Design of the sideslips measurement system of automobile
Abstract
The practice proves that the automobile sideslips can sharply increase the rolling resistance, make the driving stability become badly, accelerate the tire abrasion, waste much more and more oil and turn around heavily, affect handling property and economical efficiency of the automobile. So the automobile sideslips must be checked up for a fixed interval. This article introduces hardware and software system of automobile sideslips, principle of automobile sideslips and others principal factors. The sideslips system of automobile is constituted by input system, the output system and 80C51 micro controller unit. The measurement system accepts the signal of this sensor and then converts the signal to the sideslips value, which is displayed on the liquid-crystal display at last. If the value of sideslips goes beyond, the annunciator can send out warning tone automatically. The system of measurement can also send the measuring result to upper computer by serial port. This article mainly completes hardware and the software design of measure system of the automobile sideslips. In the hardware aspect, it introduces circuit of detection, circuit of liquid crystal display, warning circuit and so on. In the software aspect, it curtly introduces flow chart of main program and the programming method of all ports of circuit.
This design has such characters, it is suit for the simple, the high reliability, not easy to damage and so on. Automobiles sideslip system and satisfy the majority of autobile manufacturer the request.
