摘要
本文基于随车式汽车制动性能检测器介绍了三轴加速度传感器MMA7260Q的工作原理,设计了以ARM内核单片机LPC2132为核心的制动性能检测器硬件电路,对制动性能检测中的加速度进行建模、补偿和标定,完成了汽车制动性能检测器的系统设计。
Based on the in-vehicle brake performance tester, the principle of the triaxial acceleration sensor MMA7260Q is introduced, and the hardware circuit of the tester which relies on ARM-core microcontroller LPC2132 is designed. The acceleration of vehicle in process of testing is modeled, compensated and calibrated, and the design of vehicle braking performance test system is finished.
