To provide, as a countermeasure against the growing number of accidents due to incorrect depression of an accelerator pedal and a brake pedal in a vehicle, a device capable of suppressing sudden acceleration without making any erroneous actuation in the case by any chance a driver depresses incorrectly.SOLUTION: A sudden acceleration suppression device is installed between an accelerator pedal and ECU in a vehicle in which the ECU controls an engine output with a signal according to a depressed amount output from the accelerator pedal. An accelerator signal that is output from the accelerator pedal is output to the ECU as a pseudo-accelerator signal suppressed according to a travel speed of the vehicle, or in addition to performing the output as a suppressed pseudo-accelerator signal to the ECU, the suppression control is mitigated according to elapsed time, so as to enable suppression of sudden acceleration in the case that the accelerator pedal is erroneously depressed with intent to stop the vehicle.SELECTED DRAWING: Figure 1
【課題】自動車におけるアクセルペダルとブレーキペダルとの踏み間違いによる事故が多発しているため、万が一踏み間違ったとしても急加速を抑制するとともに誤作動のない装置が必要となっている。【解決手段】 アクセルペダルから出力される踏み込み量に応じた信号で、ECUがエンジン出力を制御する車両において、アクセルペダルとECUとの間に装着される急加速抑制装置であって、アクセルペダルから出力されるアクセル信号を、車両の走行速度に応じて抑制した疑似アクセル信号としてECUへ出力、または抑制した疑似アクセル信号としてECUへ出力するとともに、経過した時間により抑制制御を緩和するようにして、自動車を停止させる際に間違ってアクセルペダルを踏み込んだとしても急加速を抑制することを可能とした。【選択図】図1
