针对驾驶员需要紧急刹车时误踩油门的现象提出了一种新的处理方法,设计了一种基于MSP430单片机的智能汽车油门防误踩系统。该系统利用节气门位置传感器、测距雷达、油门压力传感器及油门加速度传感器采集汽车的行驶信息,综合这几个智能控制参数与其阈值对比并进行智能分析,最终准确判断驾驶员踩油门的意图,确认油门误踩后采取紧急制动和发动机怠速控制,最终达到安全行驶的目的。

The author proposes a new method and design of intelligent system preventing from pressing accelerator pedal mistakenly based on MSP430 when emergency braking is required. The system used the throttle position sensor,the ranging radar,the throttle pressure sensor and the throttle acceleration sensor to collect the driving information of the car,and integrated these intelligent control parameters for comparison with the threshold values and for intelligent analysis. Thus,the driver′s intention to step on the throttle is accurately determined. After the confirm of pressing accelerator pedal mistakenly,emergency braking and engine idle speed control are adopted,which finally achieve the purpose of safe driving.
