Emergency brake device in case of stepping-down of accelerator pedal instead of brake pedal by mistake

Abstract

Abstract PURPOSE:To prevent an accident due to misoperation especially on an AT car by detecting that an acceleration pedal is operated with force over a fixed value, with a pressure sensor, for cutting off an ignition circuit for an engine, while making an emergency brake possible to operate. CONSTITUTION:When an accelerator pedal 1 is stepped down with force over a fixed force on mistaking the same for a brake pedal, the operation is detected with a pressure sensor 4, an engine stop circuit connected to an ignition switch 12 inner a relay box 7 is operated, cut off on an engine ignition circuit is performed and the engine is made to stop. Lock on a stop rod 9 in a brake circuit is released at the same time, and an emergency brake is made in possible to operate. An indicator lamp 8 is lighted at this time. An accident due to misoperation especially on an AT car is prevented previously.
