Starting with our presentation day we both got on time and was ready to present our demonstration on the stage 2 which I previously mentioned was planned to show the outputs and the connectivity.

Starting with our presentation day we both got on time and was ready to present our demonstration on the stage 2 which I previously mentioned was planned to show the outputs and the connectivity.
Following were the 3 outputs mainly considered:
- Seat Belt Warning Light
- Buzzer System
- Drive By Wire Throttle
Starting from the very 1st Seat belt warning light:
As everyone knows about as it is commonly used in every car to warn the driver to wear the seat belt, it is situated in the dashboard, the main description of warning light can be as follow:
•Seat belt warning lamp must blink
for 6 seconds from IG. ON
with 0.6 sec. frequency, 50% duty, and chime bell should
ring too.
•If the
IG. is turned OFF within 6 seconds, the warning lamp and chime bell output
should be OFF.
•In case
of the seat belt switch is ON, the chime bell sound must be stopped
immediately, but seat belt warning lamp
output should be ON during 6 seconds

Second was the Buzzer system:
Alert avoid
the accidents
and for
this REMINDER with Visual Indicator is provided to
remind the driver.
Features
•If Seat Belt not fasten “After 15
second of ignition on status”. 3 times Audio massage
&
LED
•Still Seat Belt not fasten again &
again Audio & LED flash after every 20
seconds (until
seat belt fasten or mute).
DESCRIPTION:With the ignition switch turned ON and
driver seat belt unfastened, the seat belt warning chime will sound for
approximately 6 seconds.
• BCM (Body
control module) receives
seat belt buckle switch (driver seat) signal from combination meter with CAN communication
line.
• BCM detects the ignition switch turned
ON and the seat belt buckle switch (driver seat) is ON, and then
transmits buzzer
output signal (seat belt warning chime) to combination meter with CAN
communication line.
• When the combination meter receives the
buzzer output signal (seat belt warning chime), it sounds the
buzzer.
Circuit diagram:
Third and the main output for out stage two was Drive by wire throttle:
Drive
by wire which has no mechanical linkages, saves weight, is more accurate and
has better response times however the cost to make this is greater than one a
regular cable throttle.
