摘 要：提出一种基于超声波雷达的加速踏板防误踩控制系统。该系统用超声波雷达实时感知自车与障碍物的距离信息，并利用车身传感器采集和分析驾驶意图，在准确筛选出误踩加速踏板的行为后，发出声光预警信号并采取抑制整车动力输出或控制整车主动刹车的措施，以达到安全行车的目的。

Abstract: This paper proposes a control system of anti-accidental accelerator based on ultrasonic radars.The system uses ultrasonic radars to perceive the real-time distance information between self-vehicle and obstacles and uses body sensors to collect and analyze the driving intention to accurately screen out the behavior of stepping the accelerator by mistake. Then the system sends out the sound and light warning signals, and meanwhile it takes the measures of suppressing the vehicle's power output or controlling the vehicle's active braking to achieve the purpose of safe driving.
Key words: ultrasonic radar; anti-accidental accelerator; sound and light warning; power suppression; active braking
