The invention belongs to the field of electronic accelerator opening degree judgment, and particularly discloses an electronic accelerator pedal opening degree judgment method which comprises the steps that S1, a vehicle control unit collects two paths of feedback voltage; s2, the vehicle control unit judges whether the collected feedback voltage is in a normal value range or not according to the collected feedback voltage; s3, when the two paths of feedback voltages are in a normal range, the vehicle control unit calculates the opening degree of the accelerator pedal according to the voltage value fed back by the first path of accelerator pedal; when one path of feedback voltage is not in the normal range, the other path of feedback voltage is used for calculating the opening degree of the accelerator pedal; when the two paths of feedback voltages are not in the normal range, the opening degree of an accelerator pedal is set to be 0; and S4, comprehensively calculating the opening degree of the accelerator pedal according to the two paths of feedback voltages. When the electronic accelerator pedal has the electrical appliance fault, the vehicle control unit can accurately judge the opening degree of the accelerator pedal, and the life and property safety of a vehicle driver is effectively protected on the premise that the hardware cost is not increased.
本发明属于电子油门开度判断领域,具体公开了一种电子油门踏板开度判断方法,包括:S1:整车控制器采集两路反馈电压;S2:整车控制器根据采集的反馈电压判断其是否在正常值范围内;S3:当两路反馈电压都在正常的范围内时,整车控制器根据第一路油门踏板反馈的电压值计算油门踏板开度;当其中一路反馈电压不在正常范围内时,使用另外一路反馈电压计算油门踏板开度;当两路反馈电压都不在正常范围内时,将油门踏板的开度设置为0;S4:根据两路反馈电压综合计算油门踏板开度。本发明当电子油门踏板出现电器故障时,整车控制器能够准确判断油门踏板开度的特点,在不增加硬件成本的前提下,有效保护了车辆驾驶员的生命财产安全。
