The invention discloses a method and device for preventing wrong acceleration of a vehicle, and the method comprises the steps: detecting the opening degree of an accelerator pedal, the increase change rate of the opening degree of the accelerator pedal, and the collision time of the vehicle and an obstacle in the driving direction within the first time when the vehicle is backed up or taken over or after the vehicle is taken over; if the opening degree of the accelerator pedal, the increase change rate of the opening degree of the accelerator pedal and the collision time of the vehicle and the obstacle in the driving direction all meet respective threshold values, it is judged that the accelerator pedal is mistakenly stepped on, and safety protection measures are started. According to the method, the driving scene is combined, whether the accelerator pedal is mistakenly stepped or not is judged by comprehensively utilizing the accelerator pedal opening degree, the accelerator pedal opening degree increase change rate and the collision time of the vehicle and the obstacle in the driving direction, the problem that an existing accelerator mistakenly stepping prevention technology is prone to misjudgment is solved, and the judgment accuracy of mistakenly stepping the accelerator pedal is improved; in addition, safety protection measures of two stages are adopted, and the comfort of the vehicle is improved on the premise that the safety of the vehicle is guaranteed.
本发明公开了一种防止车辆错误加速的方法及装置,该方法包括:在倒车时或接管车辆时或接管车辆后的第一时间内,检测油门踏板开度、油门踏板开度增加变化率以及车辆与行驶方向障碍物的碰撞时间;如果油门踏板开度、油门踏板开度增加变化率以及车辆与行驶方向障碍物的碰撞时间均满足其各自的阈值,则判定误踩油门踏板,启动安全保护措施。本发明结合驾驶场景,综合利用油门踏板开度、油门踏板开度增加变化率以及车辆与行驶方向障碍物的碰撞时间来判定是否误踩油门踏板,解决了现有油门防误踩技术容易发生误判的问题,提高了误踩油门踏板的判断准确率;此外,采取两个阶段的安全保护措施,在保障车辆安全性的前提下提高车辆舒适性。
