Vehicle lighting systems are
extremely important specifically
from road safety considerations

A tire-pressure monitoring system (TPMS)
is an electronic system designed to monitor
the air pressure inside the pneumatic tires
on various types of vehicles. TPMS report
real-time tire-pressure information to the
driver of the vehicle, either via a gauge, a
pictogram display, or a simple low-pressure
warning light.

Active and passive safety systems have led
to a dramatic increase in electronic system
sophistication in applications like:
Active suspension
ABS and ESC

To display various parameter
of vehicle like odometer and
analog gauges for speed,
battery voltage, fuel level,
engine RPM,
and warning lights

This includes the engine,
transmission, the driveshaft,
differentials, axles, basically
anything from the engine
through to the rotating wheels.

The automotive central body control
module (BCM) is a processor-based
power distribution center that
supervises and controls functions
related to the car body such as lights,
windows, security, door locks
and access control, and
various comfort controls
