• Inadequate visibility on the roads is one of main
reasons that creates dangerous situations. Safe
speed for driving with low visibility, in rain or fog,
or dusk is the speed when the driver can stop the
car and prevent collision of cars or hitting a
pedestrian who unexpectedly appeared on the
road or when the traffic-light turned to red.
Project Goal: In case of low visibility on the road a
driver should be timely warned about change of
signal of the 'invisible' traffic-light, in order the
driver could stop the car when the light turns to
red.
Project Description:
• Traffic-light signal transmission
METHOD 1.
• At a certain distance from the traffic-light
TRAMSMITTER is installed that transmits
signals from the traffic-light. The automobile
is equipped with RECIVER that receives
signals sent by the TRANSMITTER. The
simplest transmitter — Wi-Fi transmitter.
• Maximum distance from the traffic-light to
the TRANSMITTER can be found in the Table
«Vehicle braking distance»:
• In cities for maximum permitted speed which
is 60 km/h distance from the traffic-light to
the transmitter is 35 meters.
• In town V= 60 km/h L = 35 m
• On highway V= 90 km/h L = 80 m

• Method 2.
• Traffic-light (transmitter) is connected to GSMR and transmits signal to a server. A vehicle
with GPS (receiver) transmits its geo-location
data and receives information about the
closest traffic-light.
Vehicle security system operation
• Warning of the driver
• If the RECEIVER receives a message about red
signal then windscreen «Chameleon»,
steering wheel and brake pedal receive
command «red».
• The windscreen and the steering wheel
change colour into red for 10 seconds.
• AUTOMATIC BRAKE If in 3 seconds the driver
does not push the brake pedal the vehicle
starts to slow-down automatically.
Project 2
«Smart steering wheel»
One cause of car accidents is paracenesthesia (a
deterioration in driver's sense of bodily wellbeing). The driver should be alert and not tired.
Any sickness just worsens situation.
• The most common causes of the traffic accidents:
• cardiovascular disease;
• neuralgic disease;
Project Goal: to control driver's health condition
and to prevent car accident
Project description:
• Event: frequent pulse of the driver.
• Causes:
– Stress, unrest, anger
– heart problems
– physical load
Driver's health condition monitoring:
• The steering wheel is equipped with a sensor
to control driver's pulse all the time during
driving.
Vehicle Security System Operation
• If the pulse is frequent the driver is warned to
• take a brake for 5 minutes and relax:
– relaxing music turned on
– aroma inhalation is on
Vehicle Security System Operation
•
•
•
•
«constant speed» mode is on
The vehicle controls its speed
throttle pedal is blocked
speed is limited to maximal 60 km/h
Case: dangerous bend
Case: dangerous bend
• A sensor that reads traffic sings is installed on
the car
Case: dangerous bend
• If «Dangerous bend» sign appears, cross-road
with circular movement, then:
Case: dangerous bend
• The driver is warned by SLOW-DOWN
indicator
Case: dangerous bend
• And an option to slow-down automatically
appears
Case: dangerous bend
• In case of slowing-down automatically the
onboard computer will calculate decreasing
speed
