摘 要:汽车侧滑位移是指汽车直线行驶时转向轮产生的横向位移量,是车辆安全的主要性能指标。它反映了在动态条件下汽车转向轮定位参数匹配的结果。能够精确高效地测量出汽车的侧滑位移量并判断其是否在国家规定的允许范围内,对汽车的安全问题来说越来越重要。本设计主要讨论了测量系统的软、硬件组成。通过C语言来完成程序编程和数据处理。整个系统调试与运行的核心是AT89S51单片机。该系统可完成自动检测、判别、报警与数字显示,并且成本低,性能好,稳定度高,能够精确高效地检测出汽车的侧滑量。38197 毕业论文关键词:侧滑量;单片机;位移传感器;动态检测
Design of Vehicle Sideslip Displacement Measuring System
Abstract:Vehicle sideslip displacement refers to the horizontal displacement of the steering wheel when the car is on a straight road, is the main performance indexes of vehicle safety. It reflects the dynamic conditions of steering wheel positioning parameters matching results. To accurately determine the displacement of the vehicle sideslip and determine whether the permit within the prescribed scope of the state, for the safety of the car is more and more important. Mainly discussed the design of hardware and software, the measurement system. Through the C language to complete the programming and data processing. The core of the whole system commissioning and operation of the AT89S51 microcontroller. The system can accomplish the automatic detection, identification, alarm and digital display, and low cost, good performance, high stability, can accurately and efficiently detect vehicle sideslip.
