The Need for Smart Vehicle Management System:
In a world where mobility is at the forefront of our daily lives, the demand for efficient and intelligent vehicle
management systems along with life saving tech has never been more crucial.
Challenges such as traffic congestion, fuel efficiency, and environmental concerns compel us to seek innovative
solutions that can address these issues head-on.
To implement this project, we have used the LPC1768 ARM microcontroller.
Known for its:
• robust performance,
• low power consumption
• and versatility,
This microcontroller serves as the brain behind our project, enabling seamless integration of smart features into
vehicles.

7. ABS (Anti-lock Braking System)
• It is a safety feature designed to prevent
wheel lockup during braking.
• The system is commonly used in vehicles to
enhance control and steering ability during
emergency braking situations.
• Real working :
• In ABS, as you apply the brakes, the speed
sensors track the decreasing rotation of
the wheels.
• When the brakes are about to stop rotation,
they send a signal to the electric control
unit (ECU).
• The ECU partially releases the brake pads
from the wheels through valves and pumps,
allowing the wheel to continue rotating.
• With ABS, the wheels can continue rotating,
allowing you to maintain control over the
car in a heavy braking situation.

8. Implementation
using PWM
•Apply PWM signals in increments (20%, 40%, 60%,
80%, 100%) for controlled slowing.
•Upon reaching 100% PWM, wheel halts.
•Return to normal state for wheel to resume regular
operation.

Charge Level
Indication
using ADC
• It is a critical feature that provides users with
real-time information about the remaining energy in
the vehicle's battery pack.
• Often presented graphically, with bars or a
numerical display, giving users a quick
understanding of the remaining battery capacity.
• Issues warnings or alerts when the battery level
falls below a predefined threshold, prompting
the driver to find a charging station.

15. • Implementation using ADC
• Utilize an ADC to measure the voltage,
representing the battery charge level.
• Map ADC voltage values to corresponding
battery charge levels for real-time
indication

Turn Light
Indicators

18. Implementation
using
Potentiometer
• Utilize a potentiometer for precise detection of steering
wheel rotation.
• Establish reference points: minimum, mid, and maximum
values of the potentiometer.
• Securely mount the potentiometer on the steering wheel at
the mid-value position.
• Implement automatic activation of left turn indicator
when the potentiometer value decreases (steering left).
• Implement automatic activation of right turn indicator
when the potentiometer value increases (steering right).
