<p>A pressure trigger switch-type accelerator pedal system used to correct mistaken use of an accelerator for braking, classed as an accelerator system able directly to obtain a signal indicating that the accelerator has been pressed incorrectly. A pressure trigger switch (1) is provided on the front surface or rear surface of the accelerator pedal (16), or alternatively, a pressure trigger switch (1) is provided at the part of the car bodywork (21) corresponding to the accelerator pedal (16); when a spring element in the pressure trigger switch is deformed by pressure at the switching threshold, two conducting contact elements of the switch are brought into contact, generating a switch that is switched on so that it conducts electricity; the position in which the pressure trigger switch (1) is disposed enables the switching threshold to correspond to the threshold for incorrect accelerator-pedal use; the pressure trigger switch (1) is connected to a trigger signal converter (35). The present accelerator pedal system is able directly to obtain a signal indicating that the accelerator has been pressed incorrectly, and there is no need to use a pressure sensor with a microelectronic circuit to analyse actions of accelerator-pressing at different pressures to determine whether the accelerator has been pressed incorrectly; the system has a fast response speed, simple structure, low cost and small volume; the system is easy to install, and is a reliable system for obtaining a signal indicating incorrect pressing of an accelerator.</p> |
