【摘要】 设计了一种基于MEMS加速度传感器的汽车侧翻预警系统,通过对汽车侧翻数学模型分析,以汽车发生侧翻的最大倾侧角度作为阈值门限进行预警。由MSP430F149单片机对ADXL203型加速度传感器采集的数据进行分析处理。计算出汽车当前倾侧角度和继续维持当前状态行驶至出现侧翻的时间并做出提前预警。使驾驶员能够有充足的反应时间,防止汽车产生侧翻。更多还原

【Abstract】 The pre-warning system of vehicle rollover is designed which based on dual axis MEMS accelerometer.Through analyzing the force model of vehicle rollover,it takes the maximum inclination angle when the vehicle is rolloved as the warning threshold.The data which are collected by the ADXL203 accelerometer are analysised and processed by MSP430F149 Single Chip Microcomputer,the current inclination angle and the time when the vehicle is rolloved which keep present state are calculated and advance warning is given.So that the driver can have a suffcient reaction time to avoid the vehicle rolloving.更多还原
