컴퓨터를 내장한 제어 유닛이, 구동륜의 회전 속도에 비례하는 펄스 신호에 따라 차속을 산출하는 동시에, 종동륜의 회전 속도에 비례하는 펄스 신호에 따라 의사 차속을 산출한다. 그리고, 제어 유닛은, 차속과 의사 차속 간의 비교에 근거하여, 차속 신호의 개찬 여부를 판정한다. 또한, 제어 유닛은, 차속 신호가 개찬되어 있다고 판정하는 경우, 엔진 출력을 억제하기 위하여 또 다른 제어 유닛에 개찬 검출 신호를 출력한다.

    A vehicle speed signal falsification detection apparatus has a control unit incorporating a computer. The control unit calculates a vehicle speed according to a pulse signal proportional to the rotational speed of a drive wheel and also calculates a simulated vehicle speed according to a pulse signal proportional to the rotational speed of a driven wheel. Then, the control unit determines, on the basis of the comparison between the vehicle speed and the simulated vehicle speed, whether a vehicle speed signal has been falsified. When the control unit determines that the vehicle speed signal has been falsified, then the control unit outputs a falsification detection signal to another control unit so as to suppress the output of an engine.
