\section{Description}
\begin{itemize}
\item The BSPD has the role of turning off the engine in the event of sudden braking and
acceleration of more than 10\% at the same time.
\item It compliants the 2019 rules of FSG.
The circuit works with active low logic 5V.
\item The BRAKE COMPARATOR checks that the pressure in the brake circuit is within an interval
(0 = error).
\item The THROTTLE COMPARATOR checks that the throttle is open beyond a minimum
threshold but less than 10\% (0 = error).
\item The output signals of the two comparators are in NOR (1 = error).
The resistor R = 39 k\si{\ohm} and the capacitor C = 10 uF operate a time constant of 390 ms.
\item The TIME 1 COMPARATOR determines a delay of about 500ms (496ms) in the activation of the system (0 = error).
The resistance R = 560 k\si{\ohm} and the capacitor C = 10uF operate a time constant of 5600ms.
\item The TIME 2 COMPARATOR determines a delay of about 9900ms after which the BSPD is
deactivated (RESET CONDITION) and the engine can be restarted (0 = error).
The NO RELAY performs the coupling with the car's powerline.
\item Both the brake signal and the accelerator signal are compared with two
thresholds, one upper and one lower.
\item Lower threshold: 0.45V set via resistors R102 / R116 (100 \si{\ohm}, pull-up) and R112 / R121 (10 k\si{\ohm}, pull-down).
\item Upper threshold: adjustable from 0.02 V to 5 V Set by a potentiometer M64X203KB40 R101 / R115 (10 \si{\ohm} to 2.2 M\si{\ohm}, pull-up) and a resistor (10 k\si{\ohm}, pull-down).
\item Diodes inversely polarized operate a protection against peaks on all the signals.
\item Although in the board is written "BSPD v0.2", don't worry, the version produced is v0.3 avalaible on the official site of FSG.
