The invention discloses an electric car electronic accelerator pedal signal processing method. The electric car electronic accelerator pedal signal processing method comprises the following steps thattwo ways of different simulation signals are collected, the simulation signals are converted into corresponding voltage signals, and two ways of accelerator signals are obtained; whether the two waysof accelerator signals have faults or not is judged, and whether the two ways of accelerator signals are synchronous or not is judged; a certain way of voltage signal is obtained through fault signals according to fault detection output signal state; the accelerator signals obtained after fault processing are subject to anti-jumping and deburring processing; and the accelerator signals obtained after filtering processing are subject to normalization processing. Under the conditions that the signals have abnormities, are unreasonable and have faults, non-anticipant vehicle acceleration and reduction behaviors are preve
