The invention relates to a method for calculating and processing the accelerator pedal opening degree of a pure electric vehicle. In the prior art, in calculation of the accelerator pedal opening degree without faults, processing measures are focused on consistency detection without faults or at fault state, and determination on the linearity is insufficient. The method for calculating and processing the accelerator pedal opening degree of a pure electric vehicle is provided and comprises the steps: 1, acquisition of two paths of voltage; 2, judgment on effectiveness of the two paths of voltage; 3, zero pedal opening degree identifying; 4, two paths of voltage opening degree calculating; 5, two paths of pedals linearity judging; 6, two paths of pedal synchronization degree judging; step 7,pedal opening degree output processing; and 8, virtual pedal opening degree calculating. According to the method, the opening degree of the accelerator pedal can be accurately calculated and processed, the driving requirement of a driver is met as much as possible, and safety guarantee is provided for the performance such as the dynamic property and comfort of a vehicle.

    本发明涉及一种纯电动车加速踏板开度的计算及处理方法,本发明在考虑无故障下驾驶踏板开度的计算中,对其是否发生故障及故障状态下的处理措施一方面较多集中在对其一致性的检测,而对其线性度的判断不充分,提出一种纯电动车加速踏板开度的计算及处理方法,包括步骤一:两路电压采集;步骤二:两路电压有效性判断;步骤三:0踏板开度识别;步骤四:两路电压开度计算;步骤五:两路踏板线性度判断;步骤六:两路踏板同步度判断;步骤七:踏板开度输出处理;步骤八:虚拟踏板开度计算;本发明能够较为准确的对加速踏板开度进行计算及处理,尽可能满足驾驶员的驾驶需求,为车辆的动力性及舒适性等性能提供安全保障。
