The invention discloses a method for preventing an automobile accelerator from being mistakenly stepped. The method comprises the following steps of judging whether the opening degree of an accelerator pedal reaches or exceeds an opening degree threshold value or not, and then judging whether the automobile speed reaches or exceeds a first automobile speed threshold value and a second automobile speed threshold value or not; whether the distance between a vehicle head and a front obstacle does not exceed a first distance threshold value, a second distance threshold value and a third distance threshold value or not being judged through a front camera and a front radar, and whether a driver mistakenly steps on an accelerator or not being finally judged by comprehensively analyzing accelerator pedal opening information and detection information of the front camera and the front radar; when it is determined that the accelerator is pressed by mistake, a vehicle control unit relieves an accelerator signal, and the actual accelerator opening is zeroed so that the vehicle is prevented from continuously accelerating. According to the prevention method, whether the driver steps on the accelerator by mistake or not is judged on the basis of comprehensive analysis of the accelerator pedal opening degree information and the front camera and front radar detection information, accuracy of the judgment result is higher, the influence on normal driving is small, and accidents can be more effectively prevented.
本发明公开了一种汽车油门被误踩时的防范方法,包括判断油门踏板开度是否达到或超过开度阈值,然后判断车速是否达到或超过第一车速阈值、第二车速阈值,通过前摄像头和前雷达判断车头与前方障碍物的距离是否不超过第一距离阈值、第二距离阈值以及第三距离阈值,通过综合分析油门踏板开度信息以及前摄像头和前雷达探测信息,最终判断驾车人员是否误踩油门,当判定误踩油门后,车辆控制单元解除油门信号,油门实际开度归零,从而阻止车辆继续加速。本发明的防范方法基于对油门踏板开度信息以及前摄像头和前雷达探测信息的综合分析来判断驾车人员是否误踩油门,其判断结果的准确性更高,对正常行车的影响较小,能更有效地防止事故发生。
