To provide a speed suppression device capable of reducing a vehicle speed until an accelerator is released after the vehicle speed reaches a predetermined value even, when the accelerator pedal is depressed due to a mistake in stepping while traveling.SOLUTION: A speed suppression device includes: a memory 12 in which a threshold value of a speed limit is recorded; a dummy signal generation circuit 14 for outputting an idling signal; a switching circuit 16 for outputting either an operation signal or an idling signal to an ECU as a control signal; and a microcomputer circuit 18 that compares a speed based on a vehicle speed signal with the threshold value of the speed limit and outputs a switching signal to the switching circuit 16. The microcomputer circuit 18 outputs a switching signal such that if a speed based on the vehicle speed signal is less than the threshold value, the operation signal is outputted as the control signal, and if a speed based on the vehicle speed signal is equal to or higher than the threshold value, the idling signal is outputted as the control signal.SELECTED DRAWING: Figure 1

    【課題】走行中に、踏み間違いによりアクセルペダルを踏んだ場合であっても、車両速度が所定値に達した後は、車両速度をアクセルを離すまで低下させる事ができる速度抑制装置を提供する。【解決手段】制限速度の閾値が記録されたメモリ12と、アイドリング信号を出力するダミー信号発生回路14と、操作信号とアイドリング信号とのいずれか一方を制御信号としてECUに出力する切替回路16と、車速信号に基づく速度と、制限速度の閾値とを比較して、切替回路16に対して切替信号を出力するマイコン回路18と、を備え、マイコン回路18は、車速信号に基づく速度が閾値未満である場合には操作信号を制御信号とし、車速信号に基づく速度が閾値以上である場合には、アイドリング信号を制御信号として出力するように切替信号を出力することを特徴とする。【選択図】図1
