INTRODUCTION
This design focuses on the placement of the sleeping sensors in a vehicle for maximum detection
of the driver’s eye contact, where if the driver closes his/her eyes for three seconds, the sensors
give a signal to the sleeping system which in turn uses the radar, LIDAR, cameras and parking
lights to direct the car auto drive therefore maintaining the car in the road, reducing the speed
while safely directing the vehicle for parking(Gao et al 2018). This structure attempts to
diminish, relieve or avert mishaps just as lessen the quantity of passings and wounds that happen
when the driver of an engine vehicle nods off or sleeps prompting the vehicle straying far from
the street. The design shows the sleeping sensors fitted at the on top of the rear-view mirror, right
centre windscreen board of the driver's seat and at the speedometer on the dashboard.
The sleeping system can also be fitted with an alert system for safety during driving by providing
high quality audible of surrounding areas and obstacles in the vicinity of the vehicle (Eyobu et al
2018). The sleeping system unit also includes the radar system which uses radio waves for
navigation and also to prevent accidents with respect to distance and proximity. Radio waves are
sent out and are reflected back/ bounces off upon contact with objects which makes it feasible
since they can work in all-weathers but cannot precisely differentiate objects.
PROBLEM DEFINITION
For many years, road accidents have increased due to drivers falling asleep while driving either
due to fatigue or lack of time to sleep and many other reasons. This design works to reduce,
mitigate or prevent accidents as well as reduce the number of deaths and injuries that occur when
the driver of a motor vehicle falls asleep or slumbers. The sleeping system unit also includes the
radar system which uses radio waves for navigation and also to prevent accidents with respect to
distance and proximity. Radio waves are sent out and are reflected back/ bounces off upon
contact with objects which makes it feasible since they can work in all-weathers but cannot
precisely differentiate objects.

EVALUATION
The design shows three projections of
the sleeping sensors fitted in the
vehicle giving a clear detection angle
of the driver’s eye contact. the first
sensor is fitted in the top rear-view
mirror which provides a 600 of the eye
contact.in addition, the rear view will
always be adjusted by the driver to
give him/her the rear view when
reversing, overtaking or during driving
(Kikhia et al 2018). the second sleeping
sensor is fitted at the speedometer at
the dashboard giving the upward 600
projection view of the driver's eye
contact. the third one is fitted at the
right centre board of the driver's seat
which is connected to the dashboard.
The three positions give 3600
projection view of the driver’s eye
contact hence the sensors will never
miss the eye contact.

DESIGN DESCRIPTION
SLEEPING SYSTEM - CONTROLLER
This will be a system that will manage all the inputs from the camera, the sensors, radar and
LIDAR as well as the GPS with mapping and navigation data, and will do computations upon the
driver closing eyes for 3 seconds (Miyashita, Ohmae & Tizai Keieisha 2018). The sleeping
system unit also includes the radar system which uses radio waves for navigation and also to
prevent accidents with respect to distance and proximity. Radio waves are sent out and are
reflected back/ bounces off upon contact with objects which makes it feasible since they can
work in all-weathers but cannot precisely differentiate objects.
It will confirm decisions with the aid of:
Camera
The camera is very important as it works for hand in hand with the sleeping sensors whereby it
takes images of the road which are then interpreted by the sleeping system, using the captures to
navigate the vehicle upon auto-drive mode. This structure attempts to diminish, relieve or avert
mishaps just as lessen the quantity of passings and wounds that happen when the driver of an
engine vehicle nods off or sleeps prompting the vehicle straying far from the street. The design
shows the sleeping sensors fitted at the on top of the rear-view mirror, right centre windscreen
board of the driver's seat and at the speedometer on the dashboard.
Radar

Sleeping sensors5
The sleeping system unit also includes the radar system which uses radio waves for navigation
and also to prevent accidents with respect to distance and proximity. Radio waves are sent out
and are reflected back/ bounces off upon contact with objects which makes it feasible since they
can work in all-weathers but cannot precisely differentiate objects.
The radar system will be in every side of the car so when the system will send a notification from
the radar and auto drive will turn on.
LIDAR
The sleeping system unit also includes the LIDAR system which uses light pulses for navigation.
Light pulses are sent out and reflected off upon contact with objects hence can appropriately
define lines on the road and gradually works in the dark.
The LIDAR is also very useful when the driver is navigating or parking in poor weather
conditions.
PARKING ASSIST SYSTEM
Parking assist system is a distance monitoring system that uses ultrasonic wave sensors whereby
it electronically detects the area or obstacle/object in front of your vehicle while parking and
alerts the driver with audible tones if the system detects an obstacle. However, False detection
may occur due to Heavy rain, dirty or damaged sensors may result in a false alarm.
When either the front or rear unit detects an obstruction the display will illuminate and beeping
will be heard. This beeping can be switched off by briefly pressing the button on the display of
the sleeping system integrated with the vehicles display system which will have made the driver
awake. As the obstruction gets closer the frequency of the beeps will increase and more segments
will be illuminated on the display (Tserne et al 2018). The display will also show which side the
object is (left or right).
The parking assist system will work simultaneously with the sleeping system as it will aid in
navigation of the vehicle after the sleeping system has detected the driver sleeping to maintain
the vehicle on the road, reducing the speed while moving away from other vehicles and object as
it manoeuvres away from the road so as not to cause accidents. Therefore, it will show the

accurate distance in meters or feet for computation by the sleeping system. This can also be
combined with functions such as automatic audio to alert the driver or other vehicles on the road.
This structure attempts to diminish, relieve or avert mishaps just as lessen the quantity of
passings and wounds that happen when the driver of an engine vehicle nods off or sleeps
prompting the vehicle straying far from the street. The design shows the sleeping sensors fitted at
the on top of the rear-view mirror, right centre windscreen board of the driver's seat and at the
speedometer on the dashboard.
The design can also be modified such that the system will automatically mute the car audio. thus
aids the driver to be more alert to the audible tones whenever the sleeping system has detected
closing of eyes. The sleeping system’s parking assist gives lane departure warning which helps
maintain the vehicle on the road raising a lane departure prevention notification making the
vehicle go to auto drive. The system has also a traffic sign assist under auto drive hence
preventing accidents and also obeying the laws – traffic laws.
CONCLUSION.
Therefore, this design describes the best placement of the sleeping sensors in a vehicle for
maximum detection of the driver's eye contact, where if the driver closes his/her eyes for three
seconds, the sensors give a signal to the sleeping system which in turn uses the radar, LIDAR,
cameras and parking lights to direct the car auto drive, therefore, maintaining the car in the road,
reducing the speed while safely directing the vehicle for parking. Making this positions hidden,
satisfactory to the driver and providing the best aerial view and projections so as to spot or detect
the driver's closing of eyes hence ultimately reducing the number of deaths and injuries that
occur when the driver of a motor vehicle falls asleep.
